Description

Anti-prize lock for bicycle

The utility model provides a kind of Antipicking bicycle lock, has the lock bridge that moves in lock box, the lock core of buckle lock bridge, and lock bridge inserts box.The device that belongs to the bicycle that avoids theft.

The horizontal lock that inserts on another crotch in the box of inserting of commercially available a kind of lock bridge, this lock rotates after taking to advance lock bridge, makes the insertion end of lock bridge hook the insertion box, and then realizes locking.After unblanking, the then easy hook rider of the lock bridge anyhow clothing because of returning, and insertion box is easily knocked out separately and is not widely used.Chinese patent 90210248.6 disclose a kind of have dispose the lock box bonnet of lock bridge anyhow, be hinged with axis of rotation with the hub disk of fixing fastening car crotch Guan Suohou folder, hub disk is arranged in when lock bridge is sagging and can exposes with the corresponding tightening screw of lock back folder, box is inserted then at the Antipicking bicycle lock that fastening bolt installation gap is set away from car crotch pipe side in the flat position that is covered by lock box again when stretching of lock bridge, lock bridge.

During use, clip behind the lock of lock box is rotated with after closing the car breeches pipe.Lock bridge inserts box and is anchored on another sidecar breeches pipe corresponding position.Lock is during car, with the lock box half-twist, make lock bridge corresponding with the receiver hole of lock bridge insertion box.Promotion exposes the lock bridge at lock box position, and it is moved in inserting the box hole.Flashboard imbeds the lock bridge groove to the lock box, and fixedly lock car purpose is realized in the lock bridge position.During unlatching, as long as with key turn-knob lock core, withdraw from the flashboard that imbeds groove, the lock bridge that inserts in the box is advanced lock box by the return spring bullet.90 ° of lock boxes of reverse rotation keep the lock bridge of lock box to be in vertical state again.At this moment, wheel traveling just can not be blocked.

This bicycle lock possesses tangible pick-proof performance.But, owing to use common lock core, and open back lock box rotation, both influenced outer now, also clumsy, lock bridge inserts problems such as tightening state stability that box sticks at car is not good enough, and overall performance is not very good.

At the above-mentioned deficiency of existing Antipicking bicycle lock, it is better that the utility model provides a kind of lockset to stick the tightening state at car, whole pick-proof, group higher Antipicking bicycle lock of performance.

The purpose of this utility model takes following technical measures to realize.

Configuration has how row is the lock core that radiation-like arrangement pellet shot from a slingshot stretches into blind hole in the lock box; By return spring pulling, connected the lock shelves of dialling the blocked lock bridge chase that plate stirs by lock core; Have the jacking block of the extrapolation lock bridge of return spring; The lock box that contains lock core is by having the box plate that connects car fork fastening crab bolt through hole and having box plate avris inserted block embedded groove on one side, the locking closure fastening that another side has the lock bridge patchhole forms, another side of bottom-locking plate has the b female cap plate that lid covers the lock box lock beam hole, and the corresponding locking closure lock bridge of cover plate patchhole place also is provided with lock bridge and passes through the hole; Lock bridge inserts the return spring that is provided with the pushing tow lock bridge shaft shoulder in the box, lock bridge inserts box and is connected with hinge with swivel base, configuration is reversed hinge and is made torsion spring or the elastic plate that inserts interior lock bridge trend of box and car fork shaft line parallel position in the two tray-shaped base chambeies of swivel base, be located at when lock bridge stretches into lock box and fastened by flashboard with the bolt hole of car fork tightening plate bolt on the swivel base, can be inserted on the position that lid covers.

This lock is taked following mounting method, promptly at first pull down bottom-locking plate, bolt is outwards passed the tightening plate that connects car fork opposite side from the bottom-locking plate through hole, fasten the lock box cover that contains lock core then, make the lock bridge of bottom-locking plate side b female cap plate concentric by lock bridge patchhole on hole and the lock box cover.Tight fixed bolt is connected with the tightening plate that is positioned at rear vehicle fork from positive insertion of swivel base through hole.So far full lock installs.

Using method is identical with existing Antipicking bicycle lock.

This Antipicking bicycle lock, lock core marble are radiation-like to be arranged, the anti-performance height of dialling.The concentric lock bridge that lock box cover and bottom-locking plate side are set passes through the hole, when guaranteeing that lock bridge inserts lock box, and the fastness that lock box cover and lock box base plate fasten.Anyhow insertion box cover to connect the bolt of tightening plate after the rotation, can effectively prevent to be pried open the pick-proof performance that loses because of inserting box.This lock is easy to use, and whole pick-proof performance is fabulous.
