Abstract

The utility model provides a folding bicycle, which is provided with a folding mechanism of a bicycle frame and a folding mechanism of a handlebar. The folding mechanism of the bicycle frame is that a vertical tube of the bicycle frame is cut into three sections; tooth pressing sleeves which are mutually engaged and are in a sliding fit with each other are arranged on a spindle in the vertical tube of the connecting parts among the sections; a spring is respectively arranged in the tooth pressing sleeves and a pressing handle is hinged on the spindle at the upper end of the vertical tube; the other end of the pressing handle is provided with an elastic hook corresponding to a suspension loop which is fixedly installed on an inclined fork tube; the folding mechanism of the handlebar is that a center nail in an inclined weight of a middle tube of the handlebar is arranged inversely; the thread part of the center nail passes through the middle tube of the handlebar and is connected with the handlebar on the upper end. The utility model has the advantages of folding portability, small occupation space and safety.

Description

Folding bicycle

The utility model belongs to running vehicle, particularly a kind of folding bicycle.

At present, though the folding bicycle of invention is of a great variety, adopt the wedge type or the vehicle frame folding mechanism of profile of tooth entad mostly, this mechanism structure complexity, processing charges height, binding site intensity difference, fragile, before vehicle frame folding, do not insure latching device in addition, hidden danger easily appears in riding.

The purpose of this utility model is intended to overcome above-mentioned deficiency, provides a kind of folding light, takes up an area of little, the safe and reliable folding bicycle in space.

The technical solution of the utility model realizes as follows: a kind of folding bicycle, it has vehicle frame, handlebar and folding pedals mechanism form, its unique distinction is: it is provided with vehicle frame folding mechanism, the standpipe of vehicle frame is truncated into three sections, the forked standard pipe of vehicle frame, tiltedly breeches pipe and transverse tube are welded respectively on standpipe, in, on following three sections, and sliding fit is equipped with the pressure tooth cover of mutual interlock respectively on the axle in section and the section joining place standpipe, press in the tooth cover spring is housed, be hinged with pressure handle on the axle of standpipe upper end, the other end of pressure handle is provided with and is packed in the corresponding elasticity hook of link on the oblique breeches pipe; Also be provided with the fold mechanism of handlebar, with the interior center nail upside-down mounting that tiltedly sticks together of pipe in the handlebar, its threaded portion passes to manage in the handlebar and is connected with the handle of upper end.

The utlity model has simple in structurely, folding light, take up an area of little, the durable in use advantage in space.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1, outside drawing of the present utility model;

Fig. 2, the folding back of the utility model scheme drawing;

Fig. 3, vehicle frame folding structural scheme of mechanism of the present utility model;

Fig. 4, handlebar folding mechanism scheme drawing of the present utility model.

1 vehicle frame folding mechanism among the figure, 2 handlebar folding mechanisms, 3 pedal fold mechanisms, 4 standpipes, 5 forked standard pipes, 6 oblique breeches pipes, 7 transverse tubes, 8 axles, 9 press the tooth cover, 10 springs, 11 pressure handles, 12 elasticity hooks, 13 links are managed in 14 handlebars, 15 tiltedly stick together, 16 center nails, 17 handles, 18 locknuts, 19 bearing pins, 20 handlebars.

As shown in Figure 3: will be truncated into the axle 8 of packing in three sections the standpipe 4, sliding fit is equipped with the pressure tooth cover 9 of the mutual interlock of serration on the axle 8 of 4 sections of standpipes and section joining place, spring 10 is housed pressing tooth to overlap in 9 endoporus, the locknut 18 that axle 8 lower ends are provided with is with standpipe 4 lockings and location, axle 8 upper ends are hinged by bearing pin 19 and pressure handle 11, the other end of pressure handle 11 be fixed with oblique breeches pipe 6 on link 13 corresponding elasticity hooks 12, its handlebar 20 fold mechanisms 2 are connected with handle 17 by center nail 16 upper end threaded portions after upside-down mounting that pipe 14 in the former handlebar tiltedly sticks together in 15.

If need folding bicycle, links 13 are thrown off in the hook on the pressure handle 12, after pressing springs 10 in the tooth cover 9 that the pressure tooth cover 9 of mutual interlock is thrown off, rotate on the oblique breeches pipe 6 and connect part, forward and backward wheel is closed up.By the loosening handlebar of the handle on the handlebar it is rotated again and be and the same direction of wheel promptly folding finishing.

Claims

1, a kind of folding bicycle, form by vehicle frame, handlebar and pedal mechanism etc., it is characterized in that: it is provided with vehicle frame folding mechanism, the standpipe of vehicle frame is truncated into three sections, the forked standard pipe of vehicle frame, tiltedly breeches pipe and transverse tube are welded respectively in the upper, middle and lower of standpipe on three sections, and on the axle in section and the section joining place standpipe respectively sliding fit the pressure tooth cover of mutual interlock is installed, press in the tooth cover spring is housed, hinge dress pressure handle on the axle of standpipe upper end; Also be provided with the fold mechanism of handlebar, with the interior center nail upside-down mounting that tiltedly sticks together of pipe in the handlebar, its threaded portion passes to manage in the handlebar and is connected with the handle of upper end.

2, according to right 1 described folding bicycle, it is characterized in that: the described pressure handle other end also is provided with and is packed in the corresponding elasticity hook of link on the oblique breeches pipe.
