Abstract

The utility model relates to a bicycle folding handlebar, wherein a qufu is arranged in front of a front fork central tube; the upper part of the front fork central tube is provided with a connecting base; the lower end of the handlebar is provided with a joint, the rod part is provided with a fastener; the installation method of the front fork and the handlebar vertical tube is that the joint at the lower end of the vertical tube is connected with the qufu in front of the front fork central tube through a hinge pin; the fastener at the rod part of the vertical tube is mutually locked with the connecting base at the upper part of the front fork vertical tube through a quick release bolt; in the process of folding, the quick release bolt is firstly loosened to enable the fastener and the connecting base to be separated, then the handlebar rotates forwards around the hinge pin on the qufu, and finally the handlebar rotates backwards around the axis of the front fork vertical tube, therefore, folding can be finished without a folder.

Description

A kind of bicycle folding fork handle

Technical field

The utility model relates to the handgrip of a kind of bicycle or battery-driven car, three-wheel vehicle.

Background technology

Folding bicycle is easy to carry with it and saves the characteristics of parking space and be subjected to extensively liking of people.

Common folding bicycle is a folder to be installed car beam front and back are folded for two sections on the car beam, to reduce the length of bicycle; And a folder is installed on handle riser to reduce the height of bicycle.

Folder mounting means such as Fig. 1 of handle riser as Fig. 1 (A) state, are folded into Fig. 1 (B) state by folder with it when not using when riding; This mode is being used commonplacely on the folding bicycle at present; But this folding mode is had relatively high expectations to folder, and the folder that working accuracy is low has shaking phenomenon, and the working accuracy height can increase the manufacture difficulty and the tooling cost of folder greatly; Influence outward appearance because the folder volume of installing on the handle riser is crossed conference simultaneously, too small its rigidity that can cause again is not enough, allows industry feel unsatisfactory.

Summary of the invention

The folding fork that the utility model is released is being that a kind of front fork and handle riser add the structure that several accessories combine, and it is folding not need folder just can finish.Not only simple in structure, and good rigidly, folding quick, and the height of folding rear profile tube is lower than the structure that existing great majority adopt folder.

The technical solution of the utility model is, the pipe anterior position has a fetching 02 among the front fork 01, a connecting seat 04 is arranged at the top of standpipe of front fork 03, and this Connection Block is locked on the standpipe of front fork 03 with double team or bolt, or is fixed on the pipe in the endoporus that is installed on standpipe of front fork; The place ahead of Connection Block have two stretch out forward in flakes, quick detach bolt 05 runs through two (as Fig. 2) in flakes.There is a fastener 07 in the bar portion of handle riser 06, and this fastener has a groove that Open Side Down; There is an outstanding downwards pin block 08 handle riser 06 lower end, and handle riser lower end endoporus and joint 09 be with bearing fit, can rotate each other or stretches; (as Fig. 3) is fixed in the hole of handle riser 06 upper end in the tube bank of handlebar 10 usefulness.

Front fork and handle riser installation form such as Fig. 4, the bottom of joint 09 is connected with fetching 02 usefulness bearing pin 11 on the front fork and can rotates around bearing pin 11, and the epimere of joint 09 places handle riser 06 lower end endoporus.When handle riser 06 is done anticlockwise motion when the opening of the groove of fastener 07 is positioned at the screw rod top position of quick detach bolt 05 around bearing pin 11, with car 10 to pressing down, quick detach bolt 05 is entered in the groove, the pin block 08 of handle riser 06 lower end also inserts in the groove of fetching 02 simultaneously, can pull quick detach bolt 05 fastener 07 and Connection Block 04 are locked mutually; Because the pin block 08 on the handle riser 06 is arranged in the degree of freedom that the groove of fetching 02 is limited its rotation, play the booster action that can not rotate mutually between control handle riser 06 and the front fork 01.

One-tenth car folding process such as Fig. 5 of the folding fork handle of the utility model, unclamp quick detach bolt 05 earlier, then handlebar 10 is upwards lifted together with handle riser 06, make the groove of fastener 07 and the screw rod of quick detach 05 leave (as Fig. 5 A) mutually, then handlebar 10 and handle riser 06 are forwards rotated (as Fig. 5 B) around bearing pin 11, reverse handlebar 10 again, the transverse tube axis that makes handgrip 10 is by going to and the parallel plane position of front-wheel (as Fig. 5 C) with upright position, front-wheel plane.At last with the axis back track of handgrip 10 around standpipe of front fork 03, the shaped position after finishing such as Fig. 6.

Quick detach bolt 05 is that nut 12 inboards have a boss with common quick detach bolt difference, and there is a depression sliding sleeve 13 inboards, and a spring 14 is arranged in the depression; One of fastener 07 side has a depression (as Fig. 7 A) near root of notch, when the screw rod of quick detach bolt 05 is arranged in open slot, under the effect of spring 14, nut 12 moves inward, boss is absorbed in blocking in the depression of fastener 07 side and makes screw rod can not skid off groove, even the handle accident of quick detach bolt 05 is opened like this, Connection Block 04 can not break away from fastener 07 (as Fig. 7 B) yet, and the effect of failure-free safety guard-safeguard is arranged; If in the time of will folding, must the boss of nut 12 outwards be moved with hand from the afterburning P compression spring 14 of handle one side of quick detach bolt 05, leave the depression (as Fig. 7 C) of fastener 07, fastener 07 upwards can be extracted out, begin to fold.

The specific embodiment

The connection mode of handle riser 06 and handlebar 10 is handlebar to be inserted in the hole of handle riser clamp with tube bank then, or the two makes same one.

Quick detach bolt 05 can be with style is common but stroke can satisfy the quick detach bolt of structural requirement, also can adopt the hand-screw bolt of band handle, or plain bolt, or hasp.

Connection Block 04 can be to be fixed on the standpipe of front fork 03 with the tube bank or the mode of bolted, also can install or be welded on the other pipe, then this pipe is fixed in the endoporus of vertical tube 03 (as Fig. 8).

The mounting means of fastener and Connection Block also can be with fastener and Connection Block location swap, and fastener is installed and standpipe of front fork, and on Connection Block installation and the handle riser, but the opening direction of the open slot of the fastener of this mounting means is (as Fig. 9) upwards.

Scheme shown in Figure 10 is the groove that the block 15 on the vertical tube has opening to make progress, and the quick detach bolt is by in the groove, directly with the Connection Block pressing on fastener and the handle riser.
