Ambulance stretcher combination capable of getting on and off automatically

Abstract

The invention discloses an ambulance stretcher combination capable of getting on and off automatically. The ambulance stretcher combination capable of getting on and off automatically comprises a stretcher and an ambulance. The stretcher comprises a vehicle frame and four sets of supporting leg wheel set arranged on the lower part of the vehicle frame. Each supporting leg wheel set comprises a fixed supporting leg, a rotating supporting leg, a first tension spring and a second tension spring, the upper ends of the fixed supporting legs are fixed to the bottom of the vehicle frame, and horizontal supporting members are arranged on the front side and the back side of the lower part of the fixed supporting legs. The rotating supporting legs comprise vertically arranged main supporting legs and side supporting legs vertically connected to the front sides of the upper ends of the main supporting legs. A connecting part of the main supporting legs and the side supporting legs is connected tothe lower ends of the fixed supporting legs through a rotating shaft. First casters are arranged at the lower ends of the main supporting legs, second casters are installed at the front ends of the side supporting legs, the first tension springs are fixed between the fixed supporting legs and the main supporting legs, the second tension springs are connected between the fixed supporting legs andthe side supporting legs, and a blocking member is arranged on the side, close to a vehicle door, of a bottom plate of a carriage of the ambulance. The ambulance stretcher combination capable of getting on and off automatically can enable the stretcher to get on and off more conveniently and reliably.

Description

Problems solved by technology

[0005] Although the above-mentioned stretcher car can meet the needs of getting on and off directly, its folding locking mechanism is relatively complicated. Not only the manufacturing cost is high, but also the folding locking mechanism is prone to failure. The folding of the main bracket wheel is not only inconvenient to operate, but also if the medical staff forget to unlock it, it may cause the main bracket and the ambulance to be crashed
