Description

Anti-prying cylinder lock for bicycle

The utility model is a kind of pick-proof pellet shot from a slingshot bicycle lock that is used for locking bicycle front fork (or back vent), belongs to the haberdashery and hardware class.

At present general bicycle lock has two classes haply, and a class is to be fixed in the crab claw type bicycle lock that uses on the car, though that this lock uses is more convenient, because its lock body often is made up of two chip architectures, so be easy to be pried open by the people.The another kind of chain lock that cannot not be fixing onboard, or long beam padlock, this be locked on safety, the pick-proof performance more superior than preceding a kind of lock, but because it is fixing onboard, so normal on use is carried have inconvenience more.

The purpose of this utility model is to design a kind of both safety pick-proofs, need not again to carry, novel pellet shot from a slingshot bicycle lock easy to use.

The utility model bicycle lock, lock bridge (4), dead bolt (5), dead bolt spring (6) fixed mount (7) by lock body (2), lock core (3), band draw-in groove are formed, it is characterized in that lock bridge (4) separates with lock body (2), on the upper surface of lock body (2), be shaped on two lock beam holes (10), and all correspondingly stretching in each hole has a dead bolt (5), can make two ends locking after insertion of lock bridge (4).On lock body (2) front, leave two lock beam holes (11) that pass top two axially bored lines equally, positive two hole centre distances equate with top two hole centre distances, and have only a Kong Zhongshen that dead bolt is arranged in positive two holes, so both can be after opening lock that lock bridge patchhole (11) is fixing, guaranteed that again lock is under the locking states, by hole (11) two dead bolts have not been pushed aside by the people.For realizing above-mentioned functions, can pass through different ways.Mainly by positive two holes (11) are opened on the varying level line position in lock body front, one of them and two dead bolts are in same horizon to Fig. 1 as a kind of embodiment, pick-proof in the time of so just can realizing locking, the fixing function of lock bridge during unlatching.

Secondly, have an above square groove accordingly in inboard, lock bridge both ends right, to the front and rear fork of different in width, can realize that level regulates a lock bridge length, and it is internal to make lock bridge be locked in the locational different square grooves of par.

In addition, two holes of the upper surface of above-mentioned bicycle lock (10) can distribute along the diagonal on the upper surface of lock body and be provided with, two fixed mount screws (9) are provided with along another diagonal, be fixed on car front fork (or back vent) side by fixed mount (7), thereby lock can be fixed on the car fork more firmly.

Embodiment below in conjunction with among Fig. 1 is described further the utility model, and 1 is key among the figure, and the 2nd, lock body, the 3rd, fuse, the 4th, lock bridge, the 5th, dead bolt, the 6th, dead bolt spring, the 7th, fixed mount, the 8th, bicycle front fork (or back vent), the 9th, screw, the 10th, upper surface lock beam hole, the 11st, front lock beam hole.And two screws (9) and upper surface two lock beam holes (10) are to distribute along two diagonal of the upper surface of lock body respectively, and positive two lock beam holes of lock body (11) are not on same horizon, and wherein having only to stretch in the hole has dead bolt.During use, with lock body (2) fixed mount (7), be fixed on front fork (or back vent) side pipe by two diagonal angle hold-down screws, during the locking bicycle, front fork (or back vent) opposite side pipe is inserted between " U " shape lock bridge (4), then the lock bridge two ends are inserted in two holes (10) on the lock body upper surface, inclined-plane by two dead bolts (5), compression dead bolt spring (6), make the dead bolt indentation, lock bridge continues to insert inward, and at this moment dead bolt (5) snaps in the lock bridge square groove under the elastic force effect of dead bolt spring, and can not extract.Many owing to being shaped on the lock bridge (4) to square groove, thus can be according to the width of car fork, and it is right to make dead bolt snap in different square grooves.During unlatching, use key rotation lock core, lock core upper end two cylinders are stirred two dead bolts (5) respectively, and compression dead bolt spring (6) makes the dead bolt indentation, and lock bridge both can be pulled out.After the unlatching, lock bridge can be inserted in positive two holes of lock body (11), lock bridge one end be blocked by the dead bolt in one of them hole, thereby lock bridge (4) is fixed on the lock body, need not to carry,, and do not have the overslaugh effect because lock bridge is parallel to front fork (or back vent) side pipe.

The utility model has overcome the shortcoming that existing crab claw type bicycle lock is easily pried open, and can overcome again to carry inconvenient shortcoming after chain lock and long beam padlock are opened, and is a kind of firm, insurance, bicycle lock easy to use.
