An electric manned stair stretcher with easy wheel base adjustment

Abstract

The invention is applicable to the technical field of electric stretchers, and provides an electric manned stair stretcher which is convenient for adjusting the wheel base. Two ends of the board along its length direction; moving parts, two sets of moving parts are respectively arranged on the two sets of said height-adjusting support parts. In the electric manned stair stretcher provided by the embodiment of the present invention, the moving wheel of the moving part is driven to rotate by the drive motor connected to the power supply and activated, which helps the stair stretcher to avoid obstacles such as steps and the like. It can be easily crossed; the position of the adjustment block on the extension seat can be adjusted by the adjustment assembly, so the distance between the moving wheels can be adjusted, which has wide applicability, and during the adjustment process, the moving adjustment block makes the hinged Under the connection action of the connecting rod, the linkage sprocket is pushed to move in the guide rail seat, so as to ensure the continuity of the rotation of the moving wheel driven by the driving motor.

Description

technical field [0001] The embodiments of the present invention belong to the technical field of electric stretchers, and in particular, relate to an electric manned stair stretcher that is easy to adjust the wheel base. Background technique [0002] At present, for users who do not have the ability to move autonomously in emergency situations, there are often cases where there is no elevator in the building or the elevator on the upper floor cannot quickly reach the floor where the patient is located. Back, double lift and other methods, the above methods are easy to make the patient feel uncomfortable or cause secondary damage to the user, and the efficiency of manual transfer of the user during the process of going up and down the stairs is low, and it also causes a lot of physical consumption of medical staff. [0003] Electric stretcher is a machine that uses electric drive to carry, saving material and manpower. At present, the climbing methods of the stretcher can be...
