Abstract

The utility model relates to a propulsion apparatus for non-power driven vehicle, solving the laboursome problem of the non-power driven vehicle in climbing or going to a bridge. An outer sleeve is sheathed on a flywheel, and a steel ball is arranged in a groove between the flywheel and the outer sleeve. A notch is arranged on the outer sleeve, and a spring tongue is arranged on the notch through a male pin. A convex key is arranged on the excircle of the flywheel and matched with the notch of the outer sleeve, and the outer part of the outer sleeve is provided with a cover shell whose inner part is provided with a spring. The hook part of one end of the spring is matched with the spring tongue, and the other end is arranged on the cover shell through a fixing clip. The cover shell is arranged on a transverse and a can not frame of the non-power driven vehicle through two support frames. The utility model can enhance the vehicle speed and lighten human power through the reserve and releasing power of the spring.

Description

The unpowered vehicle pusher

The utility model relates to a kind of parts on the unpowered vehicle, particularly a kind of unpowered vehicle pusher.

Current, unpowered vehicle particularly bicycle has entered huge numbers of families, and it is the walking-replacing tool of ordinary people when going out.But bicycle climbing or on during bridge, it is more painstaking that the pedaling of people stepped on, and both required great effort, and influences the speed of a motor vehicle again.

The purpose of this utility model is to provide a kind of simple in structure, easy to operate, power that can increase car, improves the speed of a motor vehicle, alleviates people's the non-locomotive pusher of pedaling the power of stepping on.

The purpose of this utility model is achieved in that and is nested with a Case of fly-wheel 2 on its flywheel 1, is provided with steel ball in the groove between the two.Have a notch on the overcoat 2, by pin 8 a clockwork spring tongue 5 is set on it.Being equipped with a protruding key 9 on the cylindrical of flywheel 1 matches with the notch of overcoat 2.The outer setting of overcoat 2 has a case 4, is provided with clockwork spring 3 in it, and an end hook portion of clockwork spring matches with clockwork spring tongue 5, and the other end is arranged on the case 4 by fixed card 7.Case 4 is arranged on the horizontal stroke of unpowered vehicle, the oblique frame by two supports 6.

Advantage of the present utility model is simple in structure, and is easy to operate, can increase power to unpowered vehicle, improves the speed of a motor vehicle, alleviates people's the power of stepping on of pedaling, and is specially adapted to non-maneuverable climbing and last bridge.Through repeatedly experiment, its result of use reaches designing requirement fully.

Below in conjunction with accompanying drawing the utility model is done more step description.

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

Fig. 2 is the birds-eye view of flywheel 1 among Fig. 1.

Fig. 3 is the structural representation of Case of fly-wheel 2 among Fig. 1.

Fig. 4 is the longitudinal sectional view of Fig. 3.

Fig. 5 is the transverse sectional view of Fig. 3.

More than structure shown in the drawings be an embodiment of the present utility model.Among the figure, 1 is flywheel, basic identical with flywheel of the prior art, just is shaped on a protruding key 9 on cylindrical, and the gear on the flywheel cylindrical has moved on on the cylindrical of overcoat 2; 2 for being nested with the Case of fly-wheel in the flywheel outside; 3 for being arranged on the clockwork spring in the case 4; 4 for being arranged on overcoat 2 exterior cases; 5 is the clockwork spring tongue that matches with clockwork spring; 6 are the horizontal stroke that case is arranged on unpowered vehicle, two supports on the oblique frame; 7 for being arranged on clockwork spring 3 fixed card in the case 4; 8 are the pin on the notch that clockwork spring tongue 5 is arranged on overcoat 2; 9 is the protruding key on flywheel 1 cylindrical; 10 are the gear (matching with the unpowered vehicle chain) on the Case of fly-wheel 2.

Unpowered vehicle is in service, and the clockwork spring tongue on the notch in the protruding key 9 on flywheel 1 cylindrical and the Case of fly-wheel 2 matches.When Case of fly-wheel 2 ahead runnings, the protruding key 9 on the flywheel is flat with 5 tops of the clockwork spring tongue on the notch in the Case of fly-wheel 2, and unpowered vehicle is normally moved.In the time will climbing or go up bridge, Case of fly-wheel 2 is moved backward, but the protruding key 9 on the flywheel is jack-up clockwork spring tongue 5 just, catch on clockwork spring 3, treat just to have produced power after clockwork spring tightens energy reserve, can promote flywheel 1 ahead running, at this moment adding normally pedaling of cyclist steps on, car power has forward just increased a lot, like this, and climbing or go up bridge just easily how.

Claims (1)
