Abstract
The invention discloses an anti-loose safety device for a bicycle folding joint. The device is arranged on a main beam tube of a frame or a riser of a handle, and consists of two connecting plates, a handle, a poking block, a bolt, a spring, and a small shaft. One side of one connecting plate is hinged with one side of the other connecting plate, and the other side of one connecting plate is hinged with the handle through the small shaft; and a group of elastic bolt which mainly comprises the poking block, the bolt and the spring is arranged on the other side of the other connecting plate. A guiding slope is formed on an end face of an inserting end of the bolt close to one side of the handle; and when the handle rotates to fold and lock the two connecting plates in place, the bolt can be automatically inserted into a positioning hole on the side surface of the handle under the action of the spring so as to prevent the handle from swinging outward. Therefore, the disconnection between the two connecting plates can be avoided. Compared with the conventional products and the prior art, the anti-loose safety device has the advantages of simple structure, easy manufacture, simple and convenient operation, safety, reliability, and attractive appearance, and can be widely applied to various folding bicycles.
Description
One, technical field
The present invention relates to the folding back of folding bicycle frame and handlebar safe locking technology, particularly be 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, summary of the invention
The objective of the invention is to provide a kind of anti-loose safety device of bicycle folding joint of simple in structure, esy to use, safe and reliable, appearance looks elegant, thereby 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 bicycle folding joint of the present invention adopts is: the present invention is installed on vehicle frame main beam pipe or the stem, is made up of two connecting panels, handle, shifting block, latch, spring and little axle.One side of described two connecting panels is mutually hinged, and wherein a plate opposite side and handle are hinged by little axle, and the opposite side of another 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 two connecting panels close up locking after the folding joint locking, corresponding position with latch, the side of handle is provided with knock hole, rotate will described two connecting panels to close up at handle and lock when putting in place, latch can insert this hole automatically, preventing that handle from outwards swinging, thereby avoid described two connecting panels to unclamp.Described latch has a guiding surface near the insertion end end face of handle one side, when operating handle closes up described two connecting panels in the locking way, latch retreats in guiding surface effect lower slider, when described two connecting panels are 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 two connecting panels firmly can not got loose after the locking.
The anti-loose safety device of bicycle folding joint of the present invention 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.
