The utility model content

The technical problem that this utility model solved is to provide portable folding chair form rescue stretcher, to solve the shortcoming in the above-mentioned background technology.

The technical problem that this utility model solved realizes by the following technical solutions:

Portable folding chair form rescue stretcher, comprise cross bar, upper bar, handle, the supporting leg pin, cradling piece, ejector pin, quarter butt, sleeve, the support bottom bar, slide block, lower pole, connecting rod, interior regulating shaft, the middle part bar, the draw ring of band self-lock pin, outer regulating shaft, bracket pins, the self-locking knob, described upper bar rear end and middle part bar front end pass through rod hinge connection, bar lower end, described middle part and lower pole front end pass through rod hinge connection, described outer regulating shaft is hinged on the bar of middle part, regulating shaft is with hinged with upper bar in described, described inside and outside regulating shaft is by the connection of the draw ring of band self-lock pin, described cradling piece upper end is hinged on connecting rod and bar junction, middle part, described cradling piece lower end and support bottom bar are hinged, and described support bottom bar is arranged in the slide block that is fixed on lower pole.

In this utility model, there is the self-locking knob described upper bar rear end.

In this utility model, two bars are fixed by cross bar about described upper bar.

In this utility model, described support bottom bar has sleeve outward.

In this utility model, U type groove and different location holes are arranged on the described sleeve.

During operation, the draw ring of pulling band self-lock pin, regulating shaft can slide relatively with outer regulating shaft in making, and then make self-lock pin enter the diverse location hole, spring in the draw ring of band self-lock pin springs into self-lock pin in the hole automatically, realize the location, thereby reach the purpose of adjustable angle, by regulating the interior regulating shaft on the stretcher, outer regulating shaft, according to sliding sleeve on the U type groove regulating shaft, and by pin and folding of spring realization stretcher and stablizing of lying status, the design of the inside and outside regulating shaft of stretcher lower part simultaneously can realize the fixing of Triangulum chair form, connecting rod and middle part bar, between the upper bar relatively rotate and lower pole and middle part bar between relatively rotate, can realize the stretcher lying status, the variation of seat state and portable folding state.

Beneficial effect

This utility model may be adjusted to folding portable stretcher, single Knapsack stretcher, double lifting type stretcher and the formula stretcher that lies low, and this utility model can be regulated chair parallactic angle degree to a certain extent when the chair type state.
