Summary of the invention

The purpose of this utility model is to provide a kind of can implement horizontal sliding or stair climbing easily, and simple in structure, simple to operation, the stair climbing horizontal sliding Two-purpose stretcher car that cost is low.

Technical solution:

This utility model comprises horizontal sliding handle, stretcher lathe body; The horizontal sliding handle is connected through rotating shaft with the stretcher lathe body, and stretcher lathe end of body is provided with the SANYE wheels, and stretcher lathe body bottom is provided with front-wheel and can decides rotating shaft; Front-wheel can be decided rotating shaft and be connected with universal wheel through changeing support arm; Can change to be provided with between support arm and the stretcher lathe body bottom and can receive arm, can receive arm and adopt linkage, linkage is provided with catch.

Said stretcher lathe body one end is provided with to fix and tiltedly pulls handle, and the other end is provided with pedal.

Said linkage is made up of last connecting rod and following side rod, and last connecting rod is connected through axle with following side rod, and the axle link of side rod is provided with catch in last connecting rod up and down.

Said stretcher lathe body both sides are separately installed with guardrail.

The stretcher lathe body is provided with seat belt.

This utility model is provided with the SANYE wheels at stretcher lathe end of body, and stretcher lathe body bottom is provided with universal wheel, and the vehicle body of stretcher and seat belt all have phosphor strip, and rescue is implemented in convenient place in dark.Can be securely fixed in relieved people or thing on the car through seat belt during rescue; During level walking; The front and rear part wheels land simultaneously, can horizontal sliding walk, and anterior wheels are regained when running into going upstairs or step; The people tiltedly draws stretcher, utilizes three wheels of the SANYE wheels at rear portion alternately to contact stair and realizes stair climbing reposefully.This utility model not only can be carried out on the level land, easily stair activity with cross over little barrier, and only need a people just can implement to rescue, adaptable across various rescue occasions.

The specific embodiment

With specific embodiment this utility model is done into description below in conjunction with accompanying drawing:

Embodiment 1

This utility model comprises horizontal sliding handle 2, stretcher lathe body 6, and horizontal sliding handle 2 is provided with grip 1, and stretcher lathe body 6 both sides are separately installed with guardrail 5; On stretcher lathe body 6, be respectively equipped with chest seat belt 7, crotch's seat belt 12 and shank seat belt 15 by the human body bed flat position, but horizontal sliding handle 2 is connected through positioning rotating shaft 4 with stretcher lathe body 6; Stretcher lathe body 6 ends are connected with SANYE wheels 13 through trilobed wheel axletree 14; Horizontal sliding handle 2 is provided with to fix with stretcher lathe body 6 junctions one end and tiltedly pulls handle 3, and stretcher lathe body 6 other ends are provided with pedal 16, but stretcher lathe body 6 bottoms are provided with front-wheel positioning rotating shaft 11; But front-wheel positioning rotating shaft 11 is connected with universal wheel 9 through changeing support arm 10; Can change to be provided with between support arm 10 and stretcher lathe body 6 bottoms and can receive arm 8, can receive arm 8 and adopt linkage, said linkage is made up of last connecting rod and following side rod; Last connecting rod is connected through axle with following side rod, and the axle link of side rod is provided with catch in last connecting rod up and down.

When using this utility model horizontal sliding rescue, but but the positioning rotating shaft 4 horizontal sliding handles 2 of pressing horizontal sliding handle 2 bottoms and stretcher lathe body 6 shapes at an angle of 90, can receive arm 8 and launch but pin front-wheel positioning rotating shaft 11, universal wheel 9 lands with the SANYE wheels simultaneously.Relieved object is placed on the stretcher lathe body 6, and foot steps down in pedal 16, prevents landing, and reuse chest seat belt 7, crotch's seat belt 12 and shank seat belt 15 are fixed, and just can the stretcher horizontal sliding be moved ahead.

When using this utility model tiltedly to pull on down the stair climbing rescue; But pin handle positioning rotating shaft 4; Horizontal sliding handle 2 rotations of stretcher lathe body 6 front ends are gone back to the both sides of a body 6; Can receive arm 8 and turn back but pin front-wheel positioning rotating shaft 11, the changeed support arm 10 of universal wheel 9 rotated to and was close to the lathe bed bottom this moment, had only the SANYE wheels 13 at rear portion to land.Relieved object is placed on the stretcher lathe body 6; Foot steps down in pedal 16; Prevent landing, reuse chest seat belt 7, crotch's seat belt 12 and shank seat belt 15 are fixed, and the people uses fixing tiltedly pulling handle 3 tiltedly to draw stretcher; Utilize fixing tiltedly pulling handle 3 tiltedly to draw stretcher, utilize three wheels of the SANYE wheels 13 at rear portion alternately to contact stair and realize stair climbing reposefully.
