[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, when the patient lies on the main body of the stretcher, the protective net is pulled out from inside the retractor box and wraps around the patient on the main body of the stretcher. The insert at one end of the protective net is inserted into the inside of the connecting frame. When the insert is inserted into the inside of the connecting frame, the locking strip is squeezed into the inside of the groove and compresses the locking spring. When the insert passes through the connecting frame, the locking strip pops out under the action of the locking spring, so that the locking strip fits against the lower end of the connecting frame, thereby facilitating the fixation of one end of the protective net, thus facilitating the protection of the patient and preventing the patient from falling during the transfer.

[0016] 2. In this utility model, when the main body of the stretcher moves, the vibration caused by the up-and-down swaying is reduced by the action of the spring damping component. At the same time, the vibration caused by the back-and-forth swaying of the stretcher main body is reduced by the action of the buffer spring, rubber strip and rubber ring, so that the overall structure has a good buffering effect and avoids secondary injury to the patient due to swaying.

The insert 9 at one end of the protective net 8 is inserted into the interior of the connecting frame 18. When the insert 9 is inserted into the interior of the connecting frame 18, the locking strip 20 is squeezed into the interior of the groove, compressing the locking spring 19. After the insert 9 passes through the connecting frame 18, the locking strip 20 pops out under the action of the locking spring 19, so that the locking strip 20 fits against the lower end of the connecting frame 18, thereby facilitating the fixation of one end of the protective net 8, thus facilitating the protection of the patient and preventing the patient from falling during transportation.

[0027] like Figure 6 As shown, the anti-fall protection structure for emergency transport provided by this utility model has a buffer structure evenly arranged at the lower end of the mounting groove. The buffer structure includes a spring damping element 10, which is fixedly installed at the lower end of the mounting groove. An assembly frame 21 is fixedly installed at the upper end of the spring damping element 10. Slide rods 22 are fixedly installed on both sides inside the assembly frame 21.
