Please refer to FIGS. 1 to 8 . In one embodiment of the present invention, the breast screening device 10 includes a device body 100 , a treatment bed 200 , a locking mechanism 300 and a limiting mechanism 400 . The device body 100 includes a sliding platform 110; the treatment bed 200 is movably mounted on the sliding platform 110, and the treatment bed 200 has a first position where it is accommodated in the sliding platform 110, and a second position where it slides out of the sliding platform 110; the treatment bed 200 includes a bed frame 210 and a caster telescopic mechanism 220, the caster telescopic mechanism 220 can move up and down relative to the bed frame 210, and has a storage state where it is accommodated in the mounting portion 211 and a supporting state where it moves to contact the ground; the locking mechanism 300 is used to lock and fix the caster telescopic mechanism 220 to the bed frame 210 when the caster telescopic mechanism 220 is in the supporting state; the limiting mechanism 400 is used to prevent the caster telescopic mechanism 220 from moving from the supporting state to the storage state when the treatment bed 200 is in the second position.

Specifically, a sliding platform 110 is provided on the device body 100, and the sliding platform 110 is roughly rectangular. The treatment bed 200 is installed on the sliding platform 110 and can slide along the length direction of the sliding platform 110. The treatment bed 200 has a use state when it is fully pulled out, and an initial state when it is retracted into the device body 100. When the treatment bed 200 is in the first position, the treatment bed 200 is in the initial state when it is retracted into the device body 100; when the treatment bed 200 is in the second position, the treatment bed 200 is in the use state when it is fully pulled out. When the breast screening device 10 needs to be used, the caster retractable mechanism 220 is generally stepped on first to make the caster retractable mechanism 220 in a supporting state in contact with the ground, and then the treatment bed 200 is pulled out along the length direction of the sliding platform 110 for use, and the treatment bed 200 is in the second position. When the breast screening device 10 is not needed, the treatment bed 200 is generally retracted from the second position to the first position, and then the caster retractable mechanism 220 is retracted so that the caster retractable mechanism 220 is in a storage state accommodated in the bed frame 210.

The treatment bed 200 includes a bed frame 210 and a caster retractable mechanism 220. The bed frame 210 is roughly in the shape of a rectangular parallelepiped frame. The caster retractable mechanism 220 is arranged at one end of the bed frame 210. The caster retractable mechanism 220 can move up and down relative to the bed frame 210 so that the casters 222 of the treatment bed 200 can be retracted or lowered to the ground. When the caster retractable mechanism 220 is in the storage state, the casters 222 of the treatment bed 200 are retracted, and when the caster retractable mechanism 220 is in the support state, the casters 222 of the treatment bed 200 are lowered to contact the ground to support the treatment bed 200.

When the caster telescopic mechanism 220 is in the supporting state, the caster telescopic mechanism 220 needs to be fixed so that the caster telescopic mechanism 220 can always be in the supporting state for the user to use. Therefore, a locking mechanism 300 is also provided, and the locking mechanism 300 can lock and fix the caster telescopic mechanism 220 so that the caster telescopic mechanism 220 can always be in the supporting state for the user to use. As for the form of the locking mechanism 300, it can be a limit by the combination of a pin and a slot, or a limit by the combination of a buckle and a slot 2211, or it can be limited by adsorption of a strong magnet. There are many ways to limit, which are not listed here one by one. In the process of short-distance transportation of the breast screening device 10, the caster telescopic mechanism 220 can be retracted to the storage state to facilitate transportation. When the breast screening device 10 needs to be used for treatment, the caster telescopic mechanism 220 is stepped down to the supporting state for use.

When the treatment bed 200 is located at the second position, the treatment bed 200 should be in use, and the caster telescopic mechanism 220 is in the supporting state, supporting the treatment bed 200. In order to prevent the user from accidentally touching the caster telescopic mechanism 220 to move from the supporting state to the storage state during the use of the breast screening device 10, a limiting mechanism 400 is further provided. The limiting mechanism 400 can limit and fix the caster telescopic mechanism 220 when the treatment bed 200 is located at the second position and the caster telescopic mechanism 220 is in the supporting state, so as to prevent the caster telescopic mechanism 220 from moving from the supporting state to the storage state.

The technical solution of the present invention is to set a caster telescopic mechanism 220 and a limiting mechanism 400 on the treatment bed 200 of the breast screening device 10, and install the caster telescopic mechanism 220 on the bed frame 210 of the treatment bed 200 so that it can move up and down. In addition, the treatment bed 200 has a first position where it is accommodated in the sliding platform 110 and a second position where it slides out of the sliding platform 110. The caster telescopic mechanism 220 has a storage state where it is accommodated in the bed frame 210 and a support state where it moves to contact the ground. The limiting mechanism 400 can prevent the caster telescopic mechanism 220 from moving from the support state to the storage state when the treatment bed 200 is in the second position. In this way, the casters 222 of the treatment bed 200 can be prevented from being easily retracted due to accidental touch by the user, which is convenient for the user to use.

Please refer to Figures 1 to 8. In one embodiment, a mounting portion 211 is provided at one end of the bed frame 210. The caster retractable mechanism 220 includes a mounting frame 221 and a caster 222. The mounting frame 221 is slidably connected to the mounting portion 211. The caster 222 is arranged at the bottom of the mounting frame 221. The limiting mechanism 400 is used to limit and fix the caster retractable mechanism 220 and the mounting portion 211 when the treatment bed 200 is located in the second position.

Specifically, the mounting frame 221 is mounted on the mounting portion 211 and can be moved in the up-down direction so that the caster telescopic mechanism 220 can be switched between the storage state and the support state. The caster 222 is arranged at the bottom of the mounting frame 221. When the caster telescopic mechanism 220 is in the support state, the caster 222 contacts the ground, and the caster 222 supports the treatment bed 200. When the treatment bed 200 is located at the second position and the caster telescopic mechanism 220 is in the support state, the mounting frame 221 and the mounting portion 211 can be locked and fixed by the locking mechanism 300 to fix the caster telescopic mechanism 220 in the support state. At the same time, the limiting mechanism 400 cooperates with the mounting frame 221 to prevent the caster telescopic mechanism 220 from moving from the support state to the storage state.

Please refer to Figures 2 to 6. In one embodiment, the limiting mechanism 400 includes a connecting member 410 and a limiting rod 420. The connecting member 410 is rotatably mounted on the mounting portion 211. The limiting rod 420 is fixedly connected to the connecting member 410. The mounting frame 221 is provided with a slot 2211. When the caster telescopic mechanism 220 is in the supporting state, the limiting rod 420 is located in the slot 2211. Specifically, the connecting piece 410 is rotatably mounted on the mounting portion 211, and the limiting rod 420 is fixedly mounted on one end of the connecting piece 410 close to the card slot 2211. When the caster telescopic mechanism 220 is in the storage state, the limiting rod 420 is located outside the card slot 2211, and the caster telescopic mechanism 220 is not limited and fixed. When the caster telescopic mechanism 220 is in the supporting state, the limiting rod 420 is inserted into the card slot 2211, so that the mounting frame 221 cannot move in the up and down directions, thereby preventing the caster telescopic mechanism 220 from being easily retracted from the supporting state to the storage state due to accidental touch by the user.

Please refer to Figures 2 to 6. In one embodiment, the limiting mechanism 400 further includes a bracket 430 and a rotating shaft 440. The bracket 430 is fixedly connected to the mounting portion 211. The connecting member 410 is rotatably connected to the bracket 430 via the rotating shaft 440, so that the connecting member 410 can rotate. Specifically, the bracket 430 is arranged in a C shape. The bracket 430 is fixedly mounted on the mounting portion 211. The connecting member 410 is connected to the bracket 430 via the rotating shaft 440. The connecting member 410 can rotate with the rotating shaft 440 as the rotation center. When the caster telescopic mechanism 220 is in the supporting state, the connecting member 410 rotates, driving the limiting rod 420 to rotate into the card slot 2211, thereby limiting the caster telescopic mechanism 220.

Referring to FIGS. 2 to 6 , in one embodiment, a mounting groove 4111 is provided on one side of the connecting member 410 away from the limiting rod 420, and connecting plates 4112 are protrudingly provided on both sides of the mounting groove 4111. The rotating shaft 440 passes through the two connecting plates 4112 to rotatably connect the connecting member 410 to the mounting bracket 221. Specifically, one end of the limiting rod 420 extends out of the connecting member 410 to extend into the clamping groove 2211 to play a limiting role, and the other end is fixedly installed in the mounting groove 4111. Connecting plates 4112 are respectively protruded on the upper and lower sides of the mounting groove 4111, and connecting holes are opened on the two connecting plates 4112. The connecting member 410 is located in the mounting groove 4111, and the rotating shaft 440 is inserted into the connecting hole on the upper side of the mounting groove 4111, and passes through the connecting plate 4112 and comes out from the connecting hole on the lower side of the mounting groove 4111 and is fixed, so that the connecting plate 4112 can rotate with the rotating shaft 440 as the rotation center.

Please refer to Figures 2 to 6. In one embodiment, the limiting mechanism 400 also includes an elastic member 450, one end of the elastic member 450 is connected to the bed frame 210, and the other end of the elastic member 450 is connected to the connecting member 410. The elastic member 450 is used to push the connecting plate 4112 to rotate around the rotating shaft 440 so that the limiting rod 420 is inserted into the slot 2211.

Specifically, one end of the elastic member 450 is fixedly connected to the mounting portion 211 of the bed frame 210. The elastic member 450 is located between the connecting member 410 and the connecting plate 4112, and can add elastic force to the limiting mechanism 400 to ensure that the limiting rod 420 of the limiting mechanism 400 can be rotated and inserted into the slot 2211 for limiting. The elastic member 450 can be set as a spring or other elastic material, and no specific limitation is made here. When the caster telescopic mechanism 220 is in the storage position, the limiting rod 420 is located outside the slot 2211 and below the slot 2211. Since the card slot 2211 is set on the mounting frame 221, when the caster telescopic mechanism 220 moves from the storage state to the supporting state, the card slot 2211 moves together with the downward movement of the mounting frame 221. When the caster telescopic mechanism 220 is in the supporting state, the limit rod 420 can be rotated and inserted into the card slot 2211 under the action of the elastic force of the elastic member 450 to limit the mounting frame 221, thereby preventing the caster telescopic mechanism 220 from moving from the supporting state to the storage state due to accidental touch or misoperation by the user, thereby affecting the use.

Please refer to Figures 2 to 6. In one embodiment, the connecting plate 4112 is further provided with a reset rod 460 at one end of the rotating shaft 440 away from the limiting rod 420. When the treatment bed 200 is located at the first position, the reset rod 460 abuts against the sliding platform 110, and the limiting rod 420 disengages from the slot 2211.

Specifically, the reset rod 460 is used to disengage the limit rod 420 from the slot 2211, so that the caster telescopic mechanism 220 can be moved from the supporting state to the storage state. The reset rod 460 and the limit rod 420 are in opposite directions, and the reset rod 460 and the limit rod 420 are respectively located at two ends of the connecting member 410, and the rotating shaft 440 is located between the reset rod 460 and the limit rod 420. When the treatment bed 200 moves from the second position to the first position, the reset rod 460 will abut against the sliding platform 110. Since the sliding platform 110 is fixed, when the reset rod 460 abuts against the sliding platform 110, the reset rod 460 will be subjected to a reverse force, so that the reset rod 460 will move in the direction opposite to the moving direction of the treatment bed 200. At this time, the connecting plate 4112 fixedly connected with the reset rod 460 will also rotate with the rotating shaft 440 as the rotation center, so that the limiting rod 420 can be disengaged from the slot 2211. At this time, the caster telescopic mechanism 220 can be moved from the supporting state to the storage state to retract the casters 222 of the treatment bed 200.

Please refer to Figures 3 to 6. In one embodiment, the breast screening device 10 further includes a first slider 500 and a first slide rail 600 that slide with each other, one of the first slider 500 and the first slide rail 600 is installed on the bed frame 210, and the other is installed on the sliding platform 110, so that the treatment bed 200 slides between the first position and the second position.

Specifically, in this embodiment, the first slider 500 is installed on the sliding platform 110, the first slide rail 600 is installed on the bed frame 210, and the treatment bed 200 can slide along the length direction of the sliding platform 110. The sliding form of the treatment bed 200 adopts the form of a slide rail and a slider, and the first slider 500 and the first slide rail 600 are slidably matched, so that the treatment bed 200 can slide on the sliding platform 110. At the same time, the first slider 500 and the first slide rail 600 also play a role in limiting the sliding direction of the treatment bed 200.

Please refer to Figures 7 and 8. In one embodiment, the treatment bed 200 further includes a second slider 230 and a second slide rail 240 that slide with each other. One of the second slider 230 and the second slide rail 240 is installed on the mounting portion 211, and the other is installed on the mounting frame 221, so that the caster telescopic mechanism 220 can move up and down relative to the bed frame 210.

Specifically, in this embodiment, the second slider 230 is fixedly connected to the mounting frame 221, the second slide rail 240 is fixedly mounted on the mounting portion 211, the mounting portion 211 extends in the up-down direction, and the caster telescopic mechanism 220 can slide in the up-down direction. The sliding form of the caster telescopic mechanism 220 adopts the form of a slider and a slide rail, the second slider 230 and the second slide rail 240 are slidably matched, so that the mounting frame 221 can slide in the up-down direction relative to the mounting portion 211, and at the same time, the second slider 230 and the second slide rail 240 also play a role in limiting the sliding direction of the mounting frame 221.

Please refer to Figures 2 and 4. In one embodiment, the locking mechanism 300 includes a locking portion 310, a limiting portion 320, a fixed shaft 330 and a foot pedal 340. The locking portion 310 is installed on the mounting portion 211 and is provided with a locking groove 311. The limiting portion 320 is provided on the mounting frame 221 and is provided with a locking head 321 adapted to the locking groove 311. The locking head 321 is located at the upper end of the limiting portion 320. The lower end of the limiting portion 320 is connected to the foot pedal 340. The limiting portion 320 and the foot pedal 340 are connected to the mounting frame 221 through the fixed shaft 330. When the caster telescopic mechanism 220 is in the supporting state, the locking head 321 is located in the locking groove 311.

Specifically, the locking portion 310 is plate-shaped and is arranged on the mounting portion 211. When the caster telescopic mechanism 220 is in the supporting state, the locking head 321 is inserted into the locking groove 311, and the mounting frame 221 no longer moves in the up-down direction, thereby limiting and fixing the caster telescopic mechanism 220, so that the caster telescopic mechanism 220 can maintain the supporting state. When the caster telescopic mechanism 220 needs to be moved from the storage state to the supporting state, it is only necessary to step on the foot pedal 340 downward with the foot, so that the mounting frame 221 can move downward, and until the locking head 321 is inserted into the locking groove 311, the caster telescopic mechanism 220 is in the supporting state. Conversely, when the caster telescopic mechanism 220 needs to be moved from the supporting state to the storage state, it is only necessary to lift the foot pedal 340 upward slightly, so that the locking head 321 can be disengaged from the locking groove 311, and then the mounting frame 221 moves upward until the caster telescopic mechanism 220 is in the storage position. It should be noted that when the caster telescopic mechanism 220 is moved from the supporting state to the storage state, it is necessary to ensure that the limiting rod 420 of the limiting mechanism 400 is disengaged from the clamping slot 2211 on the mounting frame 221 .

Please refer to FIG. 5 . In one embodiment, the treatment bed 200 further includes a bed body 250 . The bed body 250 includes a first bed body 251 and a second bed body 252 . One end of the first bed body 251 is hinged to one end of the second bed body 252 . The first bed body 251 is connected to the bed frame 210 .

Specifically, in order to reduce the lateral space of the breast screening device 10 occupied by the treatment bed 200, the treatment bed 200 can be set as a foldable treatment bed 200. The bed body 250 of the treatment bed 200 includes a first bed body 251 and a second bed body 252. The first bed body 251 can be fixedly connected to the bed frame 210 by screw connection or the like. One end of the first bed body 251 is hinged to one end of the second bed body 252 so that the second bed body 252 can be folded relative to the first bed body 251, so that the treatment bed 200 can be folded.
