Support leg gear locking device in getting-on stretcher

Abstract

The invention discloses a support leg gear locking device in a getting-on stretcher. According to the support leg gear locking device, a locking pipe with a guide channel is arranged on a framework of the stretcher, and a gear rod is inserted into the guide channel, is hinged with the upper end of a support leg, and drives the support leg to shrink inwards or stretch outwards while sliding forwards or backwards in the guide channel; at least two gear holes are arranged on the gear rod, and when the gear rod slides relative to the guide channel through guide pieces, the gear holes sequentially pass through the guide channel; a spring bolt is arranged in a pipe locking pipeline through a pushing mechanism, and when the gear rod slides in the guide channel till any gear hole is positioned in the guide channel, the spring bolt extends into the gear hole under the pushing of the pushing mechanism; a control mechanism is arranged between the lock rod and the spring bolt, and can pull out the spring bolt extending into any gear hole or prevent the spring bolt from extending into any gear hole in the guide channel. The support leg gear locking device can reliably lock the support leg in the needed position.

Description

technical field [0001] The invention relates to a boarding stretcher, in particular to a gear position locking device for the supporting legs in the boarding stretcher, which can reliably lock the supporting legs in the boarding stretcher at a desired position. Background technique [0002] Ambulances and stretchers are important equipment for medical emergency. They provide convenience for medical rescue and save precious rescue time. With the rapid development of the economy, the requirements for medical first aid equipment are also increasing, especially for emergency management and first aid equipment, such as the stretcher in the first aid equipment, when the wounded is injured, he needs to be transported on a stretcher Go to the ambulance so that the wounded can be treated in time. In the past, medical staff used hand-carried stretchers to carry the wounded to the ambulance. The hand-carried stretcher carrying the wounded was heavy, and it was very laborious to carry ...

AI Technical Summary

Problems solved by technology

Since the two supporting legs of the boarding stretcher need to be folded, the requirements for the stability of the support before the supporting legs are not folded and the flexibility of folding when folding are very high. However, the folding process of the two supporting legs of the boarding stretcher commonly used in the market It is very inflexible, which makes the process of getting on the car not easy and inconvenient to use; in addition, when transporting the wounded on flat ground, that is, when the supporting legs are extended outward to support the stretcher frame, it is also prone to supporting leg accidents due to the unstable support of the second supporting leg Folding phenomenon or shaking of supporting legs, there are potential safety hazards
