detailed description

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Fig. 1 to Fig. 8 schematically show a human body pick-and-place transport device according to an embodiment of the present invention.

As shown in FIG. 1 , the human body pick-and-place transport device includes a bracket 1 , a lifting device 2 , and clamping parts.

As shown in Figure 1, the bracket 1 includes three supports 11 and push rods 12, the support 11 in Figure 1 is X-shaped, and it can be seen from Figure 1 that there are two push rods 12, and each push rod 12 passes through the Through the upper end of the support member 11 and fixed, the push rod 12 can be used for subsequent manual pushing operations. The two sides of the X-shaped support 11 can rotate mutually (the upper right corner and the lower left corner move as one, and the upper left corner and the lower right corner move as a whole), which is similar to the "scissors" movement structure. The concrete structure of support member 11 is as follows:

As shown in Figures 3 and 4, the X-shaped support 11 includes four rotating rods 111 and an adjusting device, the adjusting device can make the four rotating rods 111 rotate mutually, and the adjusting device includes an adjusting knob 112, an inner sleeve 113, two outer sleeves 114, a shaft 115, a cam 116 sleeved on the shaft 115, a limiting member 117, a baffle plate 119 and a first rigid resisting part (not shown), the outer sleeve 114 is sleeved inside On the sleeve 113, the inner sleeve 113 is sleeved on the shaft 115, and the inner sleeve 113 is provided with a through hole 118 for the stopper 117 to protrude. The stopper 117 is connected to the blocking piece 119 through an elastic member. Always in a compressed state, both the limiting component 117 and the blocking piece 119 are provided with a first rigid resisting portion (not shown in the figure), and the two first rigid resisting portions are both located between the limiting component 117 and the blocking piece 119 . The blocking piece 119 always abuts against the cam 116 . A ring of sawtooths (not shown) is provided on the inner cavity of the outer sleeve 114 , and the elastic member pushes the limiting member 117 so that the limiting member 117 is always locked in the sawtooth.

Wherein two rotating rods 111 are arranged on one of the outer sleeves 114, and the other two transmissions are arranged on the other outer sleeve 114 (the rotating rods 111 in the upper right corner and the lower left corner in Fig. 1 are arranged on one of the outer sleeves 114 On, the turning lever 111 of upper left corner and lower right corner is located on another outer sleeve 114). The adjusting device can play the role of clamping the four rotating rods 111 .

Specifically as follows: turn the adjustment knob 112 so that the small radius of the cam 116 bears against the catch 119, and at the same time, because the elastic part connecting the stopper 117 catch 119 is in a compressed state, one end of the stopper 117 stretches out from the through hole 118, And stuck in the serrations of the outer sleeve 114, but the first rigid resisting portion of the limiting member 117 and the first rigid resisting portion of the blocking piece 119 are not in contact. Therefore, the outer sleeve 114 is in elastic contact with the limiting member 117, and the outer sleeve 114 can still rotate around the inner sleeve 113 when a certain external force is applied, and the four rotating rods 111 can rotate in pairs.

Rotate the adjustment knob 112 to rotate the shaft 115 at a certain angle, so that the large radius part of the cam 116 bears against the blocking plate 119, and the first rigid resisting portion on the blocking plate 119 contacts with the first rigid resisting portion of the blocking plate 119. Therefore, the outer sleeve 114 is in rigid contact with the limiting component 117 , and the outer sleeve 114 will not be displaced from the limiting component 117 , that is, the outer sleeve 114 cannot rotate. The four rotating rods 111 cannot rotate mutually in pairs.

When the four rotating rods 111 in the above-mentioned supporting member 11 rotate mutually in pairs, they can drive the connecting member 4 to rotate accordingly. As shown in Figure 1, there are three support members 11, and the rotating rod 111 below each support member 11 is rotatably connected with the connector 4, the connector 4 on the left is rotatably connected with the holding device 2 on the left, and the connector on the right 4 is rotatably connected with the right holding device 2, therefore, each holding device 2 is rotatably connected with three connecting parts 4, and the connecting parts 4 on both sides are preferably symmetrically distributed, and of course, can also be asymmetrically distributed. On the holding device 2, straps can also be added, the number of straps is two, one is set on each holding device, one end of the strap is arranged on the front end of the holding device 2, and the other end is arranged on the backend.

The above-mentioned rotational connection (the rotational connection between the connecting part 4 and the holding device 2, and the rotating connection between the connecting part 4 and the supporting part 11) can be clamped or loosened by the clamping part, and the specific method is as follows:

As shown in Figures 1 and 5, a first clamping member 31 is installed on the middle connector 4, and the first clamping member 31 includes a button 311, a first elastic component, a second elastic component 312, a housing 313 and a stopper 314, wherein there are two buttons 311. The button 311 at the upper end is connected to one end of the first elastic member (not shown), and the other end of the first elastic member is fixed on the shell 313 (the first elastic member here only plays the role of reset, when the button 311 is pressed When pressing down, the first elastic component is compressed, and when the button 311 is released, the first elastic component drives the button 311 to reset automatically). A sawtooth part 15 is provided at the joint between the bracket 1 and the connecting piece 4 . In Fig. 1, the sawtooth part 15 can be a part of the rotating rod 111 of the support 1 (or can also be a part of the connecting piece 4), and one end of the block 314 is matched with the sawtooth part 15, and the other end is connected with an end of the second elastic part 312. The other end of the second elastic part 312 is fixed on the shell 313, the second elastic part 312 is in a compressed state, one end of the button 311 is provided with a protrusion 3131, and the protrusion 3131 withstands the stopper 314, and makes the stopper 314 top Hold the sawtooth part 15, or the protrusion 3131 is away from the stopper 314.

As can be seen from Figure 5, when the button 311 is pressed, the button 311 will move to the left, and the projection 3131 on the button 311 will also move to the left correspondingly, so that the projection 3131 cannot resist the stopper 314, and the stopper 314 Under the action of the driving force of the second elastic part 312, the stopper 314 is still stuck in the sawtooth part 15, and at this time it is elastically snapped in, that is, the connecting part 4 can push the rotating rod 111 by applying an external force, and the sawtooth part of the rotating rod 111 15 can make the connecting piece 4 move downward, that is, the connecting piece 4 can still rotate around the lower end of the bracket. When the button 311 is released, the above-mentioned stopper 314 resets and snaps into the serrations of the sawtooth component 15 , which is rigidly snapped in. At this time, the connecting member 4 and the bracket 1 cannot rotate.

The button 311 at the lower end links to each other with one end of the first elastic component, and the other end of the first elastic component is fixed on the shell 313. On the holding device 2, a sawtooth component 15 is also provided at the junction with the connector 4, and the stopper 314 One end is matched with the sawtooth part 15, the other end is connected with one end of the second elastic part 312, the other end of the second elastic part 312 is arranged on the shell 313, and one end of the button 311 is provided with a protrusion 3131, and the protrusion 3131 withstands the blocking block 314, and make the block 314 bear against the sawtooth part 15, or the protrusion 3131 is away from the block 314. The above-mentioned block 314 blocks the sawtooth component 15 as described above, and will not be repeated here.

As shown in Figure 6, the connection relationship between the rotating rod 111 and the connecting piece 4 is now described. When the knob 321 is rotated, the elliptical rotating part 322 axially connected with the knob 321 also rotates at a certain angle (such as 90 °), the small radius part of the rotating part 322 is against the blocking plate, and because the elastic part 324 is in a compressed state, the elastic part 324 can still push the push rod 323, and the upper end of the push rod 323 is snapped into the sawtooth of the sawtooth part 15, but In order to snap in elastically, since the push rod 323 is only elastically snapped into the serrations, the connecting member 4 can still rotate around the rotating rod 111 .

Rotate a certain angle (such as 90 °), so that the large radius part of the rotating part 322 moves upward against the blocking plate, and the second rigid blocking portion 324 on the blocking plate and the second rigid blocking portion 324 on the push rod 323 contact each other, so that the pushing The rod 323 is rigidly inserted into the saw teeth, and the connecting piece 4 cannot rotate around the rotating rod 111 .

Of course, the above-mentioned second clamping member 32 can also only control the rotation of one part, such as only controlling the rotation of the holding device 2 and the connecting member 4, or the rotation of the bracket 1 and the connecting member 4, and only needs to add a second clamp. The fastening part 32 is sufficient, and at the same time, each second fastening part 32 only needs to include one push rod 323 .

As shown in Figure 1, the holding device 2 is rectangular, and there are two holding devices 2, and they are distributed symmetrically (also asymmetrically). The first roller 22, meanwhile, the third roller 25 is also installed on the upper end surface of the holding device 2, both the first roller 22 and the third roller 25 can play the role of reducing friction.
