Description

A kind of trailer

Technical field

The utility model relates to the hand barrow that can fold, and exactly is a kind of trailer that makes things convenient for transport of folded formula chair.

Background technology

The trailer of joint-stool is by the artificial trailer differentiation that is used to haul goods, original trailer is a tabular, its below is fixed with four cardan wheels, fixedly be extended with the trailer handle on one side direction, this trailer haul small article or a spot of object are very useful, and the haul chair needs special the change, the planker that is about to trailer changes bracket into, it is just enough to support chair, and there is guardrail at the edge of bracket, to prevent chair landing in the haul process.This trailer can not fold, and after a plurality of hand barrows transport article, takies too many space, be difficult to settle, though certain benefit is arranged when using, placement has but become problem, to production, dealer, to such an extent as to the end user, how to transport is the thing of a difficulty.

Some can be folded together wheel is folding, and minimizing takes up room, and can with handle and wheel is folding when trailer does not use be folded together.Though this trailer can fold, but handle can not fold trailer inside, and for easy to use, the handle design of trailer becomes to have necessarily the shape of bending forward, and handle folds back one end and still is upturned, can not avoid the shortcoming that takes up room, simultaneously, the trailer after folding for single be to have reduced shared space, but the trailer that folds after folding still needs independent placement, this is to being in the not trailer of running condition, few of practical value; For wheel, the part of the supporting construction when its retracting mechanism is the transportation object, fold the set active connection place of wheel and can destroy the steadiness and the intensity of wheel support structure, often the supporting construction of use wheel just becomes and damages easily, reduce the service life of trailer, influence the use of trailer, the mass transportation problem of same trailer does not still solve.A plurality of hand barrows transport article, can't place after using up, and take up room.

Summary of the invention

The utility model improves at the problems referred to above, makes its handle can be folded in vehicle frame inside, and minimizing takes up room, and simultaneously, can make the trailer mutual superposition together again, has solved the problem of mass transportation, can take up room as far as possible less.

The utility model is made of handle, vehicle frame, wheel and guardrail, handle upwards is fixed on the vehicle frame, wheel has four, is fixed on the bottom of vehicle frame, is characterized in that handle is movably connected on the edge of vehicle frame inboard, it can be rolled over is placed in the vehicle frame, wheel is fixed on four jiaos of the inboards of bottom of frame, and there is certain spacing on the base of each wheel and vehicle frame bottom surface, is installed with guardrail on the vehicle frame, guardrail is a framed structure, and its framework is greater than the underframe of vehicle frame.

Vehicle frame is the framed structure that supporting plate is arranged, and supporting plate is distributed in four limits of vehicle frame, and the supporting plate width that is provided with along the frame width limit is greater than the supporting plate of other position, and the support of wheel is fixed on the frame of supporting plate and vehicle frame.

Described handle, the junction of it and vehicle frame is provided with fixed link, and handle is set on the fixed link, one side of fixed link also is fixed with sliding bolt cover, the bottom of handle is fixed with the hitching post that stretches out to an example, and hitching post passes sliding bolt cover, and can handle be fixed by objects such as bolts.

Described fixed link is the taper type structure, promptly its from the top down, the diameter of fixed link is increasing.

Described guardrail, its top frame is L shaped outer rim, and the bottom surface of outer rim is fixed on the strut bar, and the strut bar rectangular distribution also is fixed on the edge of vehicle frame.

Above-mentioned guardrail, the height of its outer rim bottom surface and vehicle frame is equal to, or greater than the distance of vehicle frame bottom surface and wheel nadir.

Described wheel, the wheel that two front portions are wherein arranged is a cardan wheel, two wheel directions at rear portion are fixed.

The utility model has adopted above-mentioned frame mode, make the handle of trailer can roll over the inner space that is placed on trailer like a cork, placement wheel simultaneously also has living space, the setting of guard bar structure, make the trailer that piles up mutually stably to be fixed together, can prevent the vehicle slip each other that stacks, after finishing using in the time of to a plurality of trailer, can pile up and transport, reduce the shared space of trailer effectively, transportation can be superimposed trailer, also solved the transportation problem of a large amount of trailers, convenient and practical, and need not fold wheel, can not reduce the problem of the trailer steadiness reduction that brings thus.
