Abstract
The utility model discloses an anti-loosing safety device for folding joint of bicycle which is installed on a frame girder tube or a handlebar vertical tube, comprising a first connecting board, a second connecting board, a handle, a dial block, a plug, a spring and a small shaft. One side of the first connecting board and the second connecting board are mutually hinged, wherein the other side of the first connecting board is hinged with the handle by the small shaft. The other side of the second connecting board is provided with a set of elastic plug formed by the dial block, the plug and the spring. A guiding slope is disposed on an end face of an inserting end of the plug inserted into the handle close to one side of the handle. When the handle rotates to tightly lock the first connecting board and the second connecting board, the plug can automatically insert into a locating hole on the side of the handle under the action of spring, in order to prevent the handle from swaying outward and prevent the two connecting boards from loosening. Compared with the current products and the prior art, the utility model has the advantages of simple structure, easy operation, safety, reliability and beautiful outline. The utility model is applied to various foldable bicycles.
Description
One, technical field
The utility model relates to folding bicycle frame and the folding back of handlebar safe locking technology, particularly is applied to the anti-loose safety device in bicycle folding joint locking back.
Two, background technology
The folding joint that uses in the existing folding bicycle generally all is provided with anti-loose safe deduction structure closing up the locking back, and this mechanism mainly takes to retrain the mode of the handle that is used to operate the folding joint folding.The principle of work of this anti-loosing mechanism is, when folding joint close up put in place after latch fitting buckle into the location, then, the spin safe button is connected across the outside of handle, to prevent handle from outwards rotating folding joint is unclamped.
Yet, being used for the anti-loose safety button of bicycle folding joint at present and generally being arranged on vehicle frame main beam pipe or stem, vehicle frame main beam pipe or stem all are welded with folding joint two connecting panels respectively usually.Because various folding bicycle vehicle differences, the pipe sizing that adopted size and cross sectional shape with and the degree of dip of joining with folding joint all inequality, for example, the shape of vehicle frame main beam tube section has circle, ellipse, oblong or octagon etc., the size of pipe has large and small branch, and existing being obliquely installed in addition of pipe is horizontally disposed with, and is that the degree of dip that pipe is obliquely installed is distinguished also very big equally.Therefore, the difficulty that the anti-loose safety of this class of assembling is detained on vehicle frame main beam pipe or stem is just bigger, and the required frock clamp of different folding bicycle vehicles just can not be unified making and use.In addition, the anti-loose safety of this class is buckled in folding joint two connecting panels and closes up that the safety button can not buckle into automatically when putting in place, still needs stir with hand, so inconvenience during operating cost, add that this safety be located in the handle side and is connected across the handle outside, outward appearance is also attractive in appearance inadequately.
Three, utility model content
The purpose of this utility model is the anti-loose safety device that a kind of bicycle folding joint of simple in structure, esy to use, safe and reliable, appearance looks elegant will be provided, thereby has overcome the existing drawback that the anti-loose safe button of bicycle folding joint can not be applicable to all types of bicycles and trivial operations and safe reliability difference preferably that is used for.
The technical scheme that the anti-loose safety device of the utility model bicycle folding joint adopts is: the utility model is installed on vehicle frame main beam pipe or the stem, is made up of first and second connecting panel, handle, shifting block, latch, spring and little axle.One side of described first and second connecting panel is mutually hinged, and wherein the first connecting panel opposite side and handle are hinged by little axle, and the opposite side of second connecting panel is provided with one group of resilient pin, and described resilient pin mainly is made of shifting block, latch and spring; When just described first and second connecting panel closes up locking after the folding joint locking, corresponding position with latch, the side of handle is provided with knock hole, rotate will described first and second connecting panel to close up at handle and lock when putting in place, latch can insert this knock hole automatically, preventing that handle from outwards swinging, thereby avoid described first and second connecting panel to unclamp.The insertion end end face that described latch inserts handle near handle one side has a guiding surface, when operating handle closes up described first and second connecting panel in the locking way, latch retreats in guiding surface effect lower slider, when described first and second connecting panel is locked when putting in place mutually, latch then inserts the knock hole of handle side automatically and need not to stir latch with hand again, thereby by latch operating handle is seated described first and second connecting panel firmly can not got loose after the locking.
The anti-loose safety device of the utility model bicycle folding joint compare with existing product, technology have simple in structure, make advantage easy, easy and simple to handle, safe and reliable, appearance looks elegant, can be widely used in all kinds of Foldable cycles.
