Description

Motorcycle anti-theft lock

The utility model relates to a kind of vehicle lock, particularly anti-theft lock for motorcycle.

At present, establishing by cable that motorcycle uses shuts and the direction lock, has the shortcoming of anti-theft capability difference.On September 23rd, 1992 Chinese patent disclosure a kind of application number be the lock bridge rolling transposition formula anti-theft lock for motorcycle of " 912118830 ", it has improved this lock theftproof performance widely, but structure is comparatively complicated, this lock locking and inconvenient operation when opening.

The utility model provides a kind of structure comparatively simple, and it is light, flexible that lock bridge is shifted one's position, and is easy to operate when locking and unlatching, the anti-theft lock for motorcycle that theftproof performance is strong.

The technical scheme of the utility model anti-theft lock for motorcycle is as follows: this lock is made up of latch plate, lock bridge, lock body, rotating shaft, tapered end buckle, locking buckle etc.Lock bridge becomes the U-shaped shape, and the lock body below is provided with mutually perpendicular two base plate a, b, and two base plates and lock body longitudinal axis angle at 45 are respectively equipped with two through holes that lock bridge is passed through on a, the b base plate.Two rotating shafts symmetrically, be movably connected in the lock body both sides.In corresponding lock body of two locked grooves and rotating shaft on the lock bridge, be provided with two locking devices.Also offer a stopper slot in the lock bridge on the lock rod head, in a rotating shaft, be provided with a spacer pin accordingly.When lock bridge passes two rotating shafts, just can be between a, b two base plates half-twist.Lock body and tapered end buckle utilize buckle and hidden being bolted on motorcycle one pillar.When lock bridge passes through hole on the base plate a again, and when inserting latch plate on another pillar of motorcycle, the lock bolt in the lock body heads into two steel balls in the locked groove immediately, and at this moment, this locks into lock-out state.When key turns an angle lock core, lock bolt is return, and lock bridge can outwards be twitched, and when being evacuated to stopper slot and spacer pin in the rotating shaft contacts, lock bridge is stuck immediately, can not twitch outward again.Simultaneously, lock bridge inserts two through hole on the b base plate with two rotating shaft half-twists, presses lock bridge and pins, and at this moment, lock bridge and motorcycle pillar keeping parallelism state are extracted key out, cover the waterproof cover on the lock core, and it is very convenient to drive a vehicle.

Now be described in detail as follows to the utility model anti-theft lock for motorcycle embodiment in conjunction with the accompanying drawings:

The utility model anti-theft lock for motorcycle, it is by latch plate 1, lock bridge 2, lock body 3, rotating shaft 4,5, tapered end buckle 6, rubber cushion plate 7, lock core 10, locking buckle 15 are formed.Lock core 10 is installed in lock body 3 center, lock bridge 2 shape that takes the shape of the letter U.When this is locked in locking or opening, the longitudinal axis angle at 45 of lock bridge 2 and lock body 3.The following orientation of lock body 3 is provided with mutually perpendicular two base plate a, b, they all with lock body 3 longitudinal axis angle at 45, be respectively equipped with two groups of through holes 20,21 and 22,23 that lock bridge 2 is passed on a, b two base plates.Two rotating shafts 4,5 symmetrically, be movably connected in the both sides of lock body 3, the center line of rotating shaft 4,5 and lock body 3 axiss of pitch are same axis.The U-shaped end of lock bridge 2 is provided with the locked groove 27 of two symmetries, and a lock rod head place of the other end is provided with a stopper slot 13.Lock bridge 2 when breaking away from a, b two base plates, it and rotating shaft 4,5 can be between two vertical base plate a, b half-twist.Be provided with the hidden bolt that can not arbitrarily dismantle 16 at a base plate one end.If the user need change this lock, must at first be evacuated to the lock bridge termination in the rotating shaft 4,5, turn an angle with rotating shaft 4,5 again, make long arc groove 28 parallel with bolt 16 axis, this moment, bolt 16 just was presented on the external world, and can only could dismantle with bottle opener, otherwise was to dismantle.Moreover in a single day this lock is installed, and when this was locked in locking or unlatching, bolt 16 was in hidden state all the time, and it can't be taken apart.This just should the strong place of lock theftproof performance.

Lock body 3 and rotating shaft 4,5 and locked groove 27 corresponding sections are provided with two lock bolts, 12 devices.Rotating shaft 5 is provided with a spacer pin 11.One globular arc groove 26 is arranged at the bottom of lock body 3, and its below one end has a button platform 25, and when button platform 25 passes irregularly-shaped hole 32 in the tapered end buckle 6, and during fastening tapered end buckle 6, other end bolt 16 tightens together lock body 3 and tapered end buckle 6.The other end of lock bridge 2 is connecting latch plate 1, and just latch plate 1 is connected on another pillar of motorcycle with locking buckle 15.Key 19 turns an angle lock core 10, and lock is opening, and lock bridge 2 can outwards be twitched, and when being evacuated to stopper slot 13 and contacting with spacer pin 11, lock bridge 2 is stuck immediately, again takes out motionless.Then, again lock bridge 2 is rotated 90 ° with rotating shaft 4,5, lock bridge 2 and another pillar keeping parallelism state of motorcycle, driving is convenient.The right trough rim of stopper slot 13 is a vertical plane, and left trough rim becomes 30 ° of inclined-planes with the lock bridge rod axis.In addition, be provided with rubber cushion plate 7 in the tapered end buckle 6 of this lock and the locking buckle 15, it had both played fixing and protection motorcycle support function, simultaneously, also played antihunt action.Lock body 3 tops are provided with a waterproof cover 18, and after key was extracted out, promptly available its protection lock core 10 prevented that mud, water or other foreign matter from bringing in the lock core 10.

The utility model anti-theft lock for motorcycle, structure are comparatively simple, and be easy to use, and rolling transposition is flexible, and theftproof performance is strong.This lock core is provided with waterproof cover, prevents that effectively mud, sand, water from bringing lock core into, is a safety, reliable, practical anti-theft lock for motorcycle.Simultaneously, this lock also can be used to locking bicycle.
