When the moving plate 8 leaves the lifting block 502, the first spring 505 will be removed. When an external force is applied, the first spring 505 will return to its original state, causing the lifting block 502 to automatically reset, thereby achieving the function of the lifting block 502 automatically clamping the moving plate 8 .

Example 2

As shown in Figures 4 to 7, based on Embodiment 1, in this embodiment, the self-locking mechanism 6 includes a spur gear 601, the upper surface of the spur gear 601 is fixedly connected with a bearing rod 602, and the surface of the bearing rod 602 Rotally connected to the interior of the moving plate 8, the top end of the bearing rod 602 is fixedly connected with a first bevel gear 603, the surface of the first bevel gear 603 is meshed with a second bevel gear 604, and the axis center of the second bevel gear 604 is fixedly connected with Threaded Rod 605.

The first bevel gear 603 and the second bevel gear 604 have large loads, high centering accuracy requirements, and very high technical requirements. They inevitably have to bear huge friction during the working process. The best way is to carry out inspection on the bevel gears. Quenching heat treatment can improve its hardness, wear resistance and service life.

In this embodiment, a support block 606 is threadedly connected to the surface of the threaded rod 605, a first connection block 607 is fixedly connected to the rear of the support block 606, and a third connection bar 608 is rotatably connected to the inside of the first connection block 607 through a rotation axis. , a second connecting block 609 is rotatably connected to the inside of the third connecting bar 608 through a rotating shaft, a sliding plate 610 is fixedly connected to the rear of the second connecting block 609, and the left side of the sliding plate 610 and the right side of the second fixed baffle 9 Side sliding connection, the lower surface of the sliding plate 610 and the upper surface of the moving plate 8 are in contact with each other.

By setting the threaded rod 605 to rotate, the sliding plate 610 can move closer to the third fixed baffle 10. The third fixed baffle 10 and the sliding plate 610 will clamp the wheels of the transfer vehicle, and the transfer bed will self-lock and will not cause the patient to The pain caused the transfer bed to rock back and forth, causing the medical staff to be unable to treat the patient well.

Further, the turning mechanism 7 includes a pedal 701, the lower surface of the pedal 701 is in contact with the upper surface of the moving plate 8, the lower surface of the pedal 701 is fixedly connected with the first fixing bar 702, and the lower surface of the first fixing bar 702 is fixed. A rotating rod 703 is connected, and both ends of the rotating rod 703 are rotationally connected to the interior of the moving plate 8 .

By setting the flip mechanism 7 when the moving plate 8 is in contact with the ground, the pedal 701 will rotate ninety degrees and contact the ground. At this time, the transfer vehicle does not need to be manually lifted to the moving plate 8 by the medical staff, but only needs to be pushed to the moving plate 8 by hand. On top, the resistance will become smaller during the pushing process, reducing the physical strength of medical staff.

A second fixed bar 704 is fixedly connected to the surface of the rotating rod 703, and a sliding bar 705 is fixedly connected to the left side of the second fixed bar 704. The surface of the sliding bar 705 is slidingly connected to the inside of the moving plate 8, and the upper surface of the sliding bar 705 is fixed. A second spring 706 is connected, and the top end of the second spring 706 is fixedly connected to the inside of the moving plate 8 .

By providing the second spring 706, during the rising process of the moving plate 8, the sliding bar 705 will leave the ground. At this time, under the force of the second spring 706, the pedal 701 will rotate ninety degrees counterclockwise to the upper surface of the base 1. This ensures that the transfer vehicle will not slip during the lifting process and ensures the safety of the patient.

Working principle, when the moving plate 8 is about to contact the ground, the sliding bar 705 will slide into the inside of the moving plate 8 through the pressure of the moving plate 8 and the ground. When the sliding bar 705 slides, it will drive the second fixed bar. 704 upward, the second fixed bar 704 will drive the rotating rod 703 to rotate, the rotation of the rotating rod 703 will drive the first fixed bar 702 to rotate, the first fixed bar 702 will drive the pedal 701 to rotate, so that the pedal 701 is in contact with the ground, and the transfer vehicle moves The resistance to the moving plate 8 will become smaller, making it easier for the transfer vehicle to push onto the moving plate 8.

When the transfer vehicle is pushed onto the moving plate 8, the extension of the output end of the cylinder 403 will simultaneously drive the first connecting bar 404 and the second connecting bar 405 to rotate clockwise, and the first connecting bar 404 and the second connecting bar 405 will It will drive the second support frame 406 to rise upward and move to the left. When the moving plate 8 rises and leaves the ground, without the pressure of the ground, the sliding bar 705 will move the sliding bar 705 through the force of the second spring 706. 705 leaves the inside of the moving plate 8, the sliding bar 705 will drive the second fixed bar 704 downward, the second fixed bar 704 will drive the rotating rod 703 to rotate, the rotation of the rotating rod 703 will drive the first fixed bar 702 to rotate, and the first fixed bar 702 will rotate. 702 will drive the pedal 701 to rotate, so that the pedal 701 is in contact with the upper surface of the moving plate 8, which solves the problem of the transfer vehicle slipping during the lifting process and further ensures the safety of the patient.

When the moving plate 8 is in contact with the base 1, the spur gear 601 will mesh with the rack 3. The transfer vehicle is manually pushed to move the moving plate 8 to the left side of the base 1. During the movement, the rack 3 will drive the moving plate 8 to the left side of the base 1. The spur gear 601 rotates, the spur gear 601 drives the bearing rod 602 to rotate, the bearing rod 602 drives the first bevel gear 603 to rotate, the first bevel gear 603 drives the second bevel gear 604 to rotate, the second bevel gear 604 drives the threaded rod 605 to rotate, and the thread The rod 605 drives the support block 606 to move to the right. The support block 606 drives the third connecting bar 608 to expand through the first connecting block 607. The third connecting bar 608 moves the sliding plate 610 closer to the third fixed baffle 10 through the second connecting block 609. .

The wheels of the transfer vehicle are sandwiched between the third fixed baffle 10 and the sliding plate 610, which ensures that the transfer vehicle will not shake on the moving plate 8, and prevents medical staff from being unfavorable to the patient due to the shaking of the transfer bed. Treatment is performed because when the moving plate 8 contacts the base 1, the lifting block 502 will be pressed down. When the moving plate 8 contacts the first fixed baffle 2, the lower surface of the moving plate 8 will leave the upper surface of the lifting block 502. , the lifting block 502 will rise under the force of the first spring 505, so that the moving plate 8 is stuck between the first fixed baffle 2 and the lifting block 502, thus preventing the ambulance from moving. During the process, the moving plate 8 may shake, causing the patient to feel uncomfortable. When the transfer vehicle needs to get out of the ambulance, the moving plate 8 can be pushed out simply by pressing down on the pressing plate 501.
