When pushing the patient onto the ambulance, the medical staff can kick the pressing frame 511 to move the pressing frame 511 along the cavity on the positioning plate 402 and the slide bar 401, and the groove of the pressing frame 511 moves along the inclined surface of the pressing block 510, so that the pressing block 510 pushes the slide frame 507 on the mounting column 509 to move downward, and the insert block 506 is inserted into the groove on the collar 505, so that the four moving wheels 10 can be braked synchronously, which facilitates multi-directional transportation and braking and stopping. The vehicle body 1 can be fixed on the ambulance to prevent the ambulance from being displaced while driving.

[0038] The working principle of the vehicle body 1 for quick installation and quick braking of medical equipment is as follows: first, the medical staff holds the turntable 2 406 to drive the threaded rod 2 404 to rotate, and the threaded rod 2 404 drives the slide bar 401 to move along the outer sides of the two slide bars 2 405, so that the slide bar 401 pushes the vertical angle of the two folding frames 9 to reduce, and the folding frames 9 push the storage board 2 to move upward, and adjust the stretcher 6 and the storage board 2 to a suitable height. Then, the medical staff puts multiple medical equipment and first aid medicines between two adjacent placement boards 307 in turn, and then holds the turntable 1 303 to rotate the threaded rod 1 302, so that the threaded rod 1 302 drives the push block 304 to move along the inner side of the slide box 301, and the push block 304 can push the leftmost installation board 305 to move, so that the rubber strip 306 on the installation board 305 can press the outer side of the medical equipment, and use the medical equipment to push and contact with another rubber strip 306, thereby simultaneously pushing multiple installation boards 3 The sliding sleeve 309 on 05 moves along the outer side of the sliding rod 308 to synchronously clamp and fix multiple medical devices, and the medical staff can store the lines of the medical equipment on the inner side of the bottom of the rubber strip 306 to facilitate the arrangement of the lines. The medical staff can remove the stretcher 6, move the patient to the stretcher 6, and then install the stretcher 6 on the mounting frame 7 again, and push the vehicle body 1 to push the patient onto the ambulance. Finally, the medical staff kicks the pressing frame 511 to move along the cavity on the positioning plate 402 and the sliding bar 401, so that the groove of the pressing frame 511 moves along the inclined surface of the pressing block 510, and the pressing block 510 can push the sliding frame 507 on the mounting column 509 to move downward, and insert the insert block 506 into the groove on the ring 505, thereby synchronously braking the four moving wheels 10 to prevent the vehicle body 1 from being displaced when the ambulance is driving, thereby achieving the effect of facilitating the rapid installation and synchronous braking of multiple medical devices or first aid supplies.

Four sliding rods 13 with equal distances are fixedly connected between the top inner wall of the shell 503 and the protrusion. The sliding rods 13 slide through the outer side of the sliding frame 507. The sliding rods 13 are located on the inner side of the spring 2 508 to improve the stability of the movement of the sliding frame 507 and prevent it from tilting. Kick plates 14 are fixedly connected to both sides of the pressing frame 511 to facilitate the user to kick the pressing frame 511 to move.

[0044] In this embodiment: when the plug block 506 moves downward, it can enter the slot along the arc surface on the ring 505, thereby improving the efficiency of the plug block 506 docking with the groove, and medical personnel can push the pressure frame 511 through the kick plate 14, which is convenient for rapid adjustment of the pressure frame 511 and improves the braking efficiency of the moving wheel 10.
