Preferably, the damping assembly comprises a damping spring and a telescopic rod; the support leg comprises an upper support leg section and a lower support leg section; the top end of the upper supporting leg section is connected with the fixed support, the bottom end of the upper supporting leg section is connected with the top end of the lower supporting leg section through the telescopic rod, and the universal wheel is mounted at the bottom end of the lower supporting leg section; the shock-absorbing spring is sleeved outside the telescopic rod and connected between the upper support section and the lower support section.

Preferably, the upper leg section employs a second electrically powered rod.

Preferably, the bed further comprises a connecting plate, the end part of the telescopic rod of the first electric rod is pivoted with the connecting plate, and the connecting plate is connected with the bed board.

Due to the adoption of the technical scheme, the invention has the following beneficial effects:

through simple manual operation to and the cooperation of first electric pole, motor and revolute pair, can realize adjusting the high gradient of bed board, easy operation need not complicated maintenance, adjusts stably, realizes that the slope lets patient use the stretcher more laborsavingly.

The damping component is used for damping, so that the possibility of secondary injury of the damping force in the transportation process can be reduced; the telescopic rod arranged in the middle of the damping spring can ensure that the damping spring cannot deflect left and right in the damping process, and the damping effect is stable.

The adoption of the universal wheel can realize that more treatment time can be won by multi-angle movement.

Detailed Description

The following description of the preferred embodiment of the present invention, in accordance with the accompanying drawings of which 1 is presented to enable a better understanding of the invention as to its functions and features.

Referring to fig. 1, a self-stabilizing rescue stretcher according to an embodiment of the present invention includes a fixed bracket 1, a bed plate 2, a plurality of support legs 3, a motor 4, a plurality of revolute pairs 5, a fixed member 6, a first electric rod (not shown), a plurality of shock absorbing assemblies 7, and a plurality of universal wheels 8; two sides of the bed plate 2 are respectively connected with the fixed bracket 1 through revolute pairs 5; the motor 4 is fixedly connected with the fixed bracket 1 through a fixing piece 6; the first electric rod is in transmission connection with the motor 4, and the end part of a telescopic rod of the first electric rod is connected with the bottom of one end of the bed board 2; the supporting legs 3 are fixed at the bottom of the fixed support 1, a damping component 7 is arranged on each supporting leg 3, and a universal wheel 8 is arranged at the bottom of each supporting leg 3.

In this embodiment, the damping assembly 7 includes a damping spring 71 and a telescopic rod (not shown); the foot 3 comprises an upper foot section 31 and a lower foot section 32; the top end of the upper leg section 31 is connected with the fixed support 1, the bottom end of the upper leg section 31 is connected with the top end of the lower leg section 32 through a telescopic rod, and the bottom end of the lower leg section 32 is provided with a universal wheel 8; the shock absorbing spring is sleeved outside the telescopic rod and connected between the upper support section and the lower support section 32.

In this embodiment, the upper leg section 31 is a second electric rod.
