Abstract
The anti-theft lock for motorcycle, tricycle and bicycle consists of key, lock casing, lock body, lock core, lock bolt seat, lock bolt rod and eccentric lock bolt driving rod. The lock is welded on the front tube of the frame, the bolt rod of the lock can pass through a bolt jack arranged on the front tube of the frame and a bolt hole arranged on the vertical tube of the front fork of the vehicle and matched with the bolt hole of the front tube of the frame, and the bolt hole can enable the front fork of the vehicle to deviate from the right by an angle of 45 degrees. When in use, the lock bolt rod of the anti-theft lock can be directly inserted into the lock bolt jack of the front fork vertical pipe, and the front fork of the bicycle can not rotate after deflecting by 45 degrees, thereby achieving the purpose of locking the bicycle. The lock has simple structure, convenient processing, and can prevent prying, smashing and dismounting.
Description
The utility model relates to a kind of theftproof lock, particularly a kind of theftproof lock for motorcycle, tricycle, bicycle three usefulness.
Existing theftproof lock all is to be exclusively used on one type the car, can not be general.These lock constructions are comparatively numerous and diverse, and procedure of processing is many, and are also more numerous by dress.
Task of the present utility model be to provide a kind of can be to the general theftproof lock of polytype car.And structure, processing, by all better simply theftproof lock of dress.
The utility model is finished like this: open a lock bolt jack before the vehicle frame of motorcycle, tricycle, bicycle on the pipe, on the vertical tube of front fork of car, open again one with vehicle frame before the keyhole that is involutory of the keyhole position of pipe, this keyhole requires to make the front fork of car can be fixing on the position of right avertence 45.Before lock housing is welded in vehicle frame on the pipe before, the lock bolt rod that must make theftproof lock by vehicle frame before lock bolt jack on the pipe touch mutually with the vertical tube of front fork of car, if the front fork of car is turned right 45 °, then the lock bolt rod of theftproof lock also can directly insert among the lock bolt jack of vertical tube of front fork.This moment, the front fork of car again can not rotate, thereby reached purpose that lock is lived.Because theftproof lock is welded on the preceding pipe of vehicle frame, is difficult so will pound it.
This theftproof lock is made of key, lock housing, lock body, lock core, locking bolt seat, lock bolt rod, the eccentric driving lever of lock core.Promptly in a steel lock housing, be inserted in a lock core, this lock core be welded with an eccentric driving lever foremost, when key rotation lock core, this eccentric driving lever is rotation thereupon also; Be screwed the locking bolt seat of a kidney shape at the front end of lock body, the center of its concave surface has a circular hole that shoulder is arranged that can insert the lock bolt rod of tool semicircle head, cover one spring on lock bolt rod, make the lock bolt rod that inserts in the locking bolt seat centre bore have elasticity, and can make spring and semicircle head be stuck in the shoulder of centre bore, lock bolt rod is stretched out outside the hole; When the eccentric driving lever of lock core rotates, collide with the cup head of lock bolt rod, this lock bolt rod promptly can stretch because of the driving of eccentric driving lever, and stretching then, lock bolt rod can insert in the keyhole of preceding pipe of vehicle frame and vertical tube of front fork, make the inclined to one side 45 ° of lockings of front fork of car, or else the car front fork can freely rotate.Contracting then to make lock bolt rod withdraw from the keyhole of pipe and vertical tube of front fork before the vehicle frame, makes the rotation that affranchises of the front fork of car.
Use this theftproof lock, can be in the car manufacture process, before vehicle frame, open the keyhole identical on pipe and the vertical tube of front fork with the lock bolt rod diameter, again the lock bolt rod of theftproof lock is aimed at the keyhole place of pipe before the vehicle frame, manage and weld before lock housing is adjacent to.If fix on the position of opening with lock key at this moment, then lock bolt rod is indentation.The car front fork can freely rotate, and that is to say the car non-locking.When needs locks car, as long as lock key gone to lock bolt rod is stretched in the keyhole of pipe before the vehicle frame, car vertical tube of front fork, extract lock key, then this car is locked, and the front-wheel of this car is to be fixed on to take over to change the locational of 45.This sample car can not promote forward, and can only turn-take.If lift front-wheel, it is just very difficult to push away away this car; It also is impossible pounding this lock, tear lock open and also have no way of doing it.
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing 1 be this theftproof lock by dress back schematic diagram;
Accompanying drawing 2 is theftproof lock profile schematic diagrames;
Accompanying drawing 3 is the structural representations after theftproof lock is thrown off lock housing;
Accompanying drawing 4 is theftproof lock assembly structure decomposing schematic representations.
In conjunction with the accompanying drawings, a kind of motorcycle, tricycle, the general theftproof lock of bicycle are made up of lock key (1), lock housing (2), lock core fixed screw (3), lock body (4), lock core (5), lock bolt rod (6), locking bolt seat (7), locking bolt seat fixed screw (8), the eccentric driving lever (9) of lock core, lock core end face (10), lock core retainer ring (11).On its lock core end face (10) eccentric driving lever (9) is housed, the eccentric driving lever of lock core (9) is collided with the cup head of lock bolt rod (6), because of being with spring (12) on the lock bolt rod (6), inserts it in locking bolt seat (7) centre bore.This Kong Youyi step (shoulder) can be given spring and cup head location.When the eccentric driving lever of lock core (9) rotated, lock bolt rod (6) promptly can stretch.Its locking bolt seat (7) is a kidney shape, and two ends have screw (8 '), and available screw (8) matches fixing with lock body.
The lock housing (2) of this theftproof lock is made arc, the preceding pipe of its arc-shaped concave and vehicle frame is adjacent to mutually, make lock bolt rod (6) aim at the keyhole of being opened on the preceding pipe of vehicle frame, can weld fixing.And manage the circular hole that the 45 that takes on the same horizon of keyhole is opened a same diameter before making car front fork and vehicle frame, can supply lock bolt rod (6) to insert.The theftproof lock that assembles can use, simple, easy to process, the anti-pick-proof of pounding of this anti-theft lock structure.
Claims (3)
1, a kind of motorcycle, tricycle, bicycle three are used theftproof lock, form by lock housing, lock core, lock bolt rod, it is characterized in that on the lock core end face (10) of lock core (5) front end of this lock the eccentric driving lever (9) of a lock core being housed, at lock body (4) front end locking bolt seat (7) is housed, and fixing with screw (8); Have a circular hole that step (shoulder) arranged in the centre of locking bolt seat (7), establish a lock bolt rod (6) that is with spring (12) in this hole, the head of this lock bolt rod (6) is semicircular, and collides with the eccentric driving lever of lock core (9); The jack of this lock bolt rod (6) is opened before vehicle frame on pipe and the car vertical tube of front fork; Must make lock bolt rod (6) and two jack contrapositions with managing before theftproof lock and the vehicle frame when welding.
