Description
Technical field
The present invention relates to a kind of boarding stretcher, more particularly to a kind of supporting leg in boarding stretcher can be positively locked in institute
Need supporting leg gear locking device in the boarding stretcher of position.
Background technology
Ambulance, stretcher are the important equipments of medical first aid, and they provide convenience for medical rescue, have saved preciousness
Rescue time.With economic fast development, the requirement to medical first aid equipment is also improved constantly, especially for first aid pipe
Reason, first-aid equipment propose requirement higher, such as stretcher in first-aid equipment, when the wounded are injured, it is necessary to be transported him with stretcher
It is sent on ambulance, to give treatment to the wounded in time.Past medical personnel are to be carried on the wounded using hand lift formula stretcher
Ambulance, is loaded with the hand lift formula stretcher heavier-weight of the wounded, and very laborious during carrying, travelling speed is also relatively slow, medical personnel's
Physical demands is very big, the phenomenon for easily occurring wounded's aggravation caused by repeatedly moving in use in addition, uses
It is dangerous.
A kind of boarding stretcher is occurred in that in the market, and the boarding stretcher includes carrying the stretcher of patient, supports stretcher
The supporting leg of stretcher framework and support stretcher framework, two supporting legs are separately positioned on the front and rear both sides of stretcher lower frame,
Two supporting leg bottoms are provided with wheel, and boarding stretcher is quick on the ground by being arranged at the wheel of two supporting leg bottoms
It is mobile, so as to quickly transport the wounded.Two supporting legs of the boarding stretcher can be folded, so, in upper ambulance, medical care people
The wounded can be pushed to ambulance by member together with boarding stretcher.Because two supporting legs of boarding stretcher need to fold, this is right
The requirement on flexibility folded when the steadiness of the unfolded front support of supporting leg and folding is very high, but common in the market
Boarding stretcher two supporting leg folding processes it is very inflexible, this causes that the process of getting on the bus is not light, in-convenience in use；Separately
When the wounded are transported on external level land, i.e., when supporting leg flexes outward support stretcher framework, also easily occur because of the support of two supporting legs not
Consolidate and supporting leg accident Fold or supporting leg shaking phenomenon occur, there is potential safety hazard.
The content of the invention
