Abstract

The utility model relates to a bicycle handlebar stem quick folding device. The device is characterized in that a cardinal axis type folding device is fixed between an upper folding connecting pipe and a lower folding connecting pipe of the handlebar stem; the cardinal axis type folding device comprises an upper folding body and a lower folding body which are fastened by a quick release locking component and are connected with each other by a connecting gland; the upper folding body consists of a body connecting axis and a connecting through hole fixed with the upper folding connecting pipe; the body connecting axis is perpendicular to the connecting through hole; the lower folding body is goose head-shaped; the gooseneck end of the lower folding body is provided with a connecting hole fixed with the lower folding connecting pipe, while the goose head end is provided with a combining hole inserted with the body connecting axis of the upper folding body; the combining hole is provided with a fastening opening; and the upper part of the fastening opening is provided with a quick release locking component hole, and runs through and is connected with the quick release locking component. The bicycle handlebar stem quick folding device has the advantages that the handlebar stem can be quickly folded and restored along the axial line by means of the directional rotation of the folding device, thereby reducing the positional space of the handlebar and ensuring the stability and flexible and quick folding of the folding handlebar stem during riding.

Description

The cycle arm quick folding device

Technical field

The utility model belongs to attachments of a bicycle, relates in particular to a kind of cycle arm quick folding device that is applicable to that various vehicles are used.

Background technology

At present, the bicycle handle bar of selling on the market all is an one with a horizontal stroke, and its width is between 480-600mm.Bicycle handlebar when depositing maximum that takes up room.When bicycle storing during at public building door, park several bicycles simultaneously after, will influence people and come in and go out.Because handlebar is wide, cause waste for the space of storage park.The bicycle of releasing in the market that has the upright device of folding grip, because folding grip is upright is to be divided into up and down two folding adapters to form, and the apparatus structure of the similar hinge of connected fixedly upset folding device causes that folding grip is upright built on the sand, to amount to action dumb not quick yet.

The utility model content

The purpose of this utility model is to overcome the defective that above-mentioned technology exists, and provide a kind of cycle arm quick folding device, adopt hinge formula folding device that upright the rotation by the orientation of folding device along its axis rapidly of the handle of handlebar finished folding and reposition, both can reduce the locational space of handlebar, when having guaranteed again that folding grip is upright and having ridden firmly, operation simultaneously amounts to flexible movements, quick.

The utility model for achieving the above object, by the following technical solutions: a kind of cycle arm quick folding device, comprise that the handles that are divided into two folding adapters up and down are upright, it is characterized in that: the captive joint hinge formula folding device between two folding adapters the up and down that described handle is upright, described hinge formula folding device comprises the folding body, under roll over body and fastening and with connecting the gland connection by the quick detach latch assembly, the described folding body of going up is made up of the connecting through hole that the body connecting shaft reaches and last folding adapter is affixed, described body connecting shaft is vertical with connecting through hole to be provided with, the described body profile of folding down is gooseneck boom shape, its gooseneck ends is provided with and folds the affixed connecting bore of adapter down, the gooseneck boom end is provided with the body connecting shaft grafting combined hole with last folding body, described combined hole is provided with secured opening, and secured opening top is provided with quick detach locking component holes and runs through and connects the quick detach latch assembly.

The described interior both sides of combined hole of rolling over body down are provided with positioning groove relatively, and the described body connecting shaft of going up the folding body is provided with elongated slot, and elongated slot is built-in to be equipped with the folding navigation button of spring and to roll over body up and down by connecting the gland connection.

The beneficial effects of the utility model: adopt hinge formula folding device that upright the rotation by the orientation of folding device along its axis rapidly of the handle of handlebar finished folding and reposition, both can reduce the locational space of handlebar, when having guaranteed again that folding grip is upright and having ridden firmly, operation simultaneously amounts to flexible movements, quick.
