Abstract
The utility model relates to a wheel buckling theft-proof lock for a bicycle. A movable arm is arranged between a lock body and a lock rod; one end of the movable arm is hinged with a lock body, and the movable arm is provided with a spring; the other end of the movable arm and one end of the lock rod form a deflector rod mechanism; the locking and the unlocking are flexible. The utility model solves the problem that in the prior art, the wheel buckling theft-proof lock has the disadvantages of inconvenient use, complicated structure, etc. The utility model has the advantages of convenient use, simple structure, firmness and prying resistance.
Description
The utility model relates to a kind of bicycle sprocket wheel formula theftproof lock.
Existing bicycle sprocket wheel formula theftproof lock, when unblanking, locking bar is difficult for ejecting automatically return; When sealed, often an action can not be finished, and has brought many inconvenience to the user in use, automatic function is perhaps arranged but complex structure.
The purpose of this utility model provides a kind of unblanking and sealed all very convenient and firm bicycle sprocket wheel formula theftproof lock simple in structure.
The purpose of this utility model is achieved in that the utility model mainly is made up of lock body, locking bar, lock-opening mechanism and lever arm.Be provided with a lever arm between lock body and locking bar, an end of lever arm is connected with lock body with hinge axis, forms a hinge, is provided with a spring on hinge, and it can be a torsion spring, also can be leaf spring etc.; One end of the other end of lever arm and locking bar forms a lever body, the lever arm swing can make locking bar parallel moving in pilot hole, this lever body as: can on lever arm, have a chute, locking bar is provided with a sliding axle, and sliding axle slides in chute and realizes locking bar parallel moving under the swing of lever arm; Also can be connected with an end of lever arm with the end of a little axle with locking bar, the length of lever arm is stretched with the swing of lever arm and is realized the translation of locking bar in pilot hole.When sealed, promote lever arm, locking bar pilot hole on lock body under the drive of lever arm pushes lock body, and dead bolt snaps in the locking bar draw-in groove, forms closed hoop, and at this moment spring is compacted; When unblanking, lock-opening mechanism withdraws from dead bolt from the locking bar draw-in groove, and on lever arm, lever arm drives locking bar and is ejected into the enable possition automatically spring with the elastic force release action.Lock body preferably adopts casting, and lock-opening mechanism preferably is fabricated directly on the lock body, and its closed hoop and lock-opening mechanism all are difficult for being pried open, and unblanks to have realized the purpose of this utility model with sealed all very convenient.
Owing to adopted such scheme, the utility model uses very convenient, firm again pick-proof simple in structure.
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is Figure 1A-A sectional view;
Fig. 3 is that Fig. 1 F is to partial view;
Embodiment of the present utility model such as Fig. 1, Fig. 2, shown in Figure 3.Mainly form by lock body 1, locking bar 3, lock-opening mechanism 9 and lever arm 2.Be provided with a lever arm 2 between lock body 1 and locking bar 3, an end of lever arm 2 is connected with lock body 1 with hinge axis 6, forms a hinge, is provided with a torsion spring 4 on hinge; The other end of lever arm 2 has a chute 7, and the sliding axle 5 on the locking bar 3 can slide in chute 7.When sealed, promote lever arm 2, locking bar 3 pushes lock body 1 along pilot hole 11 under the drive of lever arm 2, and dead bolt 8 snaps in the draw-in groove 10 of locking bar 3, forms closed hoop, and at this moment torsion spring 4 is compacted; When unblanking, lock-opening mechanism 9 withdraws from dead bolt 8 from draw-in groove 10, and on lever arm 2, lever arm 2 drives locking bar 3 and ejects automatically torsion spring 4, because the length of chute 7 is certain, stops automatically when locking bar 3 is bound to the enable possition with the elastic force release action.Lock body 1 adopts casting, and lock-opening mechanism 9 is fabricated directly on the lock body 1, and closed hoop and lock-opening mechanism 9 all are difficult for being pried open, and unblank with sealed all very convenient.
