Description

A kind of Foldable pushcart

Technical field

The utility model relates to a kind of People-Powered Vehicle, relates in particular to a kind of Foldable pushcart.

Background technology

Existing hand barrow all is made up of handrail, vehicle frame and wheel, and wheel is contained in below the vehicle frame, and handrail is contained in above the vehicle frame and is high together with people's waist, and structure is all fairly simple, and general volume is bigger, carries and deposit all inconvenient.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of Foldable pushcart.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of Foldable pushcart, be made up of handrail, vehicle frame and wheel, described handrail is hinged on by jointed shaft on the journal stirrup of vehicle frame, and handrail bottom cross-under has the pin axle, described journal stirrup is provided with the U type groove that rotates for the pin axle, is provided with extension spring between described pin axle and the jointed shaft;

As further improvement in the technical proposal, two pores of described handrail are provided with and the corresponding real core plastic plug of pore.

The beneficial effects of the utility model are: when needs fold handrail, at first jam on the pin axle, make pin axle stretching extension spring, rotating handrail simultaneously makes handrail rotate around jointed shaft, and the pin axle turns to the other end from an end of U type groove, because under the tension and compression of extension spring, the assurance handrail is stable to be folded on the vehicle frame; When needs move on to normal use location with handrail, directly rotate handrail and make the pin axle be fixed on the another location of U type groove, and under the tension and compression of extension spring, fix, can normally use.Because the handrail of this product has folder function, thereby be easy to carry and deposit.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a folded state scheme drawing of the present utility model;

Fig. 3 is an A of the present utility model place cut-away view.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, a kind of Foldable pushcart, formed by handrail 1, vehicle frame 2 and wheel 8, described handrail 1 is hinged on the journal stirrup 21 of vehicle frame 2 by jointed shaft 7, handrail 1 bottom cross-under has pin axle 3, described journal stirrup 21 is provided with the U type groove 4 that rotates for pin axle 3, is provided with extension spring 5 between described pin axle 3 and the jointed shaft 7.

This product be in order to make handrail 1 easily folding, when the handrail pull-up is normally used, because of handrail 1 push away or when drawing 2 stressed, be difficult for distortion in order to make handrail 1 bottom tube wall, ad hoc be equipped with two with the corresponding real core plastic plug 6 of pore.

The principle of work of this product is: when needs fold handrail 1, at first jam on pin axle 3, make the 3 stretching extension springs 5 of pin axle, rotating handrail 1 simultaneously makes handrail 1 rotate around jointed shaft 7, and pin axle 3 turns to the other end from an end of U type groove 4, owing under the tension and compression of extension spring 5, guarantee handrail 1 stable being folded on the vehicle frame 2; When needs move on to normal use location with handrail 1, directly rotate handrail 1 and make pin axle 3 be fixed on the another location of U type groove, and under the tension and compression of extension spring 5, fix, can normally use.Because the handrail 1 of this product has folder function, thereby be easy to carry and deposit.
