Preferred as technique scheme, described fixed frame is fixed by self reserving between the unmoving axle that adds long nut and brake wheel and main body frame the realization crab-bolt, makes the automatic brake arrangement overall fixed in the inner space of unmoving axle one side of brake wheel.

The beneficial effects of the utility model are: because the brake wheel of band automatic brake arrangement has been installed on main body frame, for closing the state of stopping, need be pressed brake operation mechanism during the personnel operation go-cart under its normality, and the brake equipment state is gone to the pine state of stopping; When go-cart disengaging personnel controlled, brake operation mechanism upspring automatically, and automatic brake arrangement reverts to braking state automatically, thereby can effectively avoid slipping the generation of dangerous situations such as car, and safety is very good.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is an integral structure scheme drawing of the present utility model;

Fig. 2 is an automatic brake arrangement structural representation of the present utility model;

Fig. 3 is a brake wheel structural representation of the present utility model.

The specific embodiment:

See shown in Figure 1: a kind of autobrake rail pedestrian of the present utility model tries hard to recommend car, include main body frame 10, hutching handrail 20, main body frame 10 is equipped with a pair of common wheel 30 and a pair of brake wheel 40, hutching handrail 20 is fixed near on the main body frame 10 of brake wheel 40 1 sides, the top of hutching handrail 20 is provided with two brake operation mechanisms 50, and brake operation mechanism 50 links to each other with automatic brake arrangement in the brake wheel 40 by brake drive link 60.

See shown in Figure 2: the automatic brake arrangement in the brake wheel 40 includes brake facing 71, braking plectrum 72, plectrum status adjustment bar 73, permanent retarding spring 74, and retracing spring 75, wherein, one end of brake facing 71 links to each other with fixed frame 70, the other end is close to braking plectrum 72, an end that applies to the braking plectrum 72 of the permanent thrust of wheel direction to brake facing 71 under the normality links to each other with fixed frame 70, the other end links to each other with an end of plectrum status adjustment bar 73, the other end of plectrum status adjustment bar 73 links to each other with an end of brake drive link 60 and permanent retarding spring 74 simultaneously, the other end of permanent retarding spring 74 links to each other with fixed frame 70, one end of retracing spring 75 links to each other with fixed frame 70, and the other end links to each other with brake facing 71.
