Abstract

The utility model discloses a foldaway bicycle which comprises a front wheel, a rear wheel, a joystick, a cushion rod, a chain plate and a pedal, wherein, a base is fixed at the lower end of the cushion bar; the pedal is installed on the base, the front end of which is hinged with the back ends of a pair of parallel connecting rods; the front ends of the connecting rods are hinged with a fixed block which is arranged on the middle part of the joystick; meanwhile, the connecting rods are hinged with a slide block which is spanned above the back of the base by a middle lever; the rear end of the base is hinged with the chain plate and a rear fork rod which connects the rear wheel part. The front wheel, the rear wheel, the joystick, the connecting rod which connects the front wheel part, and the rear fork rod which connects the rear wheel part of the utility model can rotate oppositely to the base and enable the whole body to be folded completely, thereby obtaining the effect of smallest volume; the folding type bicycle has simple and compact structure and is very convenient to operate.

Description

Folding Bicycle

Technical field:

The utility model relates to the athletic sports appliance technical field, especially relates to a kind of folding bicycle.

Background technology:

Bicycle is a kind of common vehicle, and its pattern is varied, and traditional bicycle major part can't fold, and carries and transport comparatively inconvenience; Also can see some Foldable bicycles in the market, but the fold mechanism complexity of these bicycles, operate very inconveniently, in addition, folding effect is also undesirable, and the volume after folding is still bigger, can't satisfy user's needs.

The utility model content:

The purpose of this utility model is the weak point that exists at prior art and a kind of simple in structure, easy to operate, minimized Folding Bicycle of volume after folding is provided.

For achieving the above object, the utility model includes front-wheel, trailing wheel, joystick, seat cushion bar, chain dish, foot-operated, wherein, the lower end of seat cushion bar is fixed with pedestal, foot-operated being installed on the pedestal, and the rear end of the front end of pedestal and the connecting rod of pair of parallel is hinged, the front end of connecting rod is then hinged with the fixed block that is located at the joystick middle part, simultaneously, connecting rod via intermediate bar with to be crossed on the crotch of pedestal back upper place hinged, the rear end of pedestal and chain dish and to be connected the rear fork of trailing wheel hinged.

The connecting rod inboard of described pair of parallel is respectively equipped with a slide block, and two slide blocks are hinged with the two ends of a trace respectively.

Also be hinged with a radius stay on the described seat cushion bar, offer the through hole that passes for radius stay on the pedestal.

After adopting technique scheme, the beneficial effects of the utility model are: the connecting rod of its front-wheel, trailing wheel, joystick and connection front-wheel part all can rotate relative to pedestal with the rear fork that is connected the trailing wheel part, make whole locomotive body can fold gathering fully, reach the minimized effect of volume, it is simple and compact for structure, and operation is very easy.

Description of drawings:

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

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

The specific embodiment:

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See shown in the accompanying drawing 1: include front-wheel 10, trailing wheel 20, joystick 30, seat cushion bar 40, chain dish 50, foot-operated 60; Wherein, the lower end of seat cushion bar 40 is fixed with pedestal 70, and foot-operated 60 are installed on the pedestal 70.The rear end of the front end of pedestal 70 and the connecting rod of pair of parallel 81,82 is hinged, and the front end of connecting

rod

81,82 is then hinged with the fixed block 31 that is located at joystick 30 middle parts, and simultaneously, connecting rod 82 is hinged with the crotch 84 that is crossed on pedestal 70 back upper places via intermediate bar 83; , connecting

rod

81,82 inboards are respectively equipped with a slide block in addition, and two slide blocks are hinged with the two ends of a trace 86 respectively.The rear end of pedestal 70 and chain dish 50 and to be connected the rear fork 85 of trailing wheel 20 hinged.

When needs get up bicycle folding, can be with pedestal 70 front ends and the upwards pulling of connecting

rod

81,82 hinged portion, the connecting

rod

81,82 that links to each other with joystick 30 is under the effect of slide block and trace 86, drive front-wheel 10 and joystick 30 anticlockwise motions, simultaneously, chain dish 50 and trailing wheel 20 clockwise direction under the effect of rear fork 85 rotates, and makes folding gathering the in seat cushion bar 40 both sides of front and back two parts of bicycle.

In addition, also be hinged with a radius stay 41 on the seat cushion bar 40, when bicycle was in open mode, the lower end of radius stay 41 withstood on the pedestal 70; And after the folding gathering of the front and back of bicycle two parts, rotatable radius stay 41 makes its front end insert the through hole that is opened in pedestal 70 middle parts, removes the constraint to seat cushion bar 40, make seat cushion bar 40 also can be passed down through pedestal 70 and contraction, thereby reduce the bicycle height after folding gathering the in.
