Abstract

The utility model relates to an anti-theft lock for a bicycle. The structure of the anti-theft lock for a bicycle is a fully closed mechanism which is composed of a lock body, a groove plate, a lock body support plate, and a lock core component. The anti-theft lock for a bicycle has the performance that the anti-theft lock for a bicycle is not easy to prize, tamp, and drive to be unlocked, wherein, a novel circular key is adopted to make the teeth number of the novel circular key achieved 16384 kinds. In addition, the novel circular key is not easily matched, and therefore, the secrecy degree of the anti-theft lock for a bicycle is enhanced. The anti-theft lock for a bicycle widely adopts the essences of various locks. The anti-theft lock for a bicycle has compact structure, beautiful shape, and high firmness. The anti-theft lock for a bicycle is an ideal anti-theft lock.

Description

Bicycle lock

A kind of bicycle lock, have anti-dial, anti-sledge, anti-ly pound, security performance such as secrecy height.

The utility model is in order to satisfy above-mentioned performance demands, and it adopts rotatable 90 degree frids and lock body and a chain of sealing of base plate and lock core component controls mechanism composition, and adopts a kind of novel key, and its different tooth numbers are up to 16384 kinds.

Structure of the present utility model is described in detail as follows in conjunction with the accompanying drawings:

Fig. 1 is the utility model elevation;

Fig. 2 is the utility model left view;

Fig. 3 is the utility model lock core parts elevations;

Fig. 4 is the utility model key elevation;

Fig. 5 is the utility model key A-A sectional view.

As shown in Figure 1, 2, the utility model bicycle lock is made up of lock body (4), lock body base plate (6) (8) torsion spring I (3), sheathing (2), frid (1), lock core parts (7), fastening devices (9), label (10) etc.Lock body (4) is riveted together by 4 countersunk not chipped rivets (5) and lock body base plate (6) (8); Label (10) is by 2 snap rivets (11) and lock body base plate (6) (8) riveted joint.

As shown in Figure 3, the utility model lock core parts (7) by lock core shaft (16), lock core cover (15), key (17), stop (12), sheave (13), torsion spring II (24), spring (23), up and down tack pellet shot from a slingshot (21) (22), decorate core (20) etc. and form.By lock core shaft (16) other parts are installed, block by back-up ring (25) and prevent that part from falling.Then, by alignment pin (14) lock core parts (7) are fixed in the lock body (4).

As shown in Figure 4, key of the present utility model is made up of key bit (19), the shank of the key (18), forms by riveted joint.

As shown in Figure 5, be the utility model key A-A sectional view, be to process the little circular arc in 7 places at its cylindrical place by special purpose machine tool.

When this lock cuts out,, locking is closed to the right with the direct inverted draw cut plate (1) of hand.When lock is opened, key (17) is inserted in lock body (4) hole, participate to turning clockwise, at this moment key (17) drives lock core shaft (16), stop (12) rotates, make stop (12) break away from frid (1) and go up square groove, under the effect of torque spring, sheave (13) rotates, at this moment frid is moving linearly left, locks into opening.

This lock has compact conformation with similar phase-locked ratio, production technology advanced person, and the modern design uniqueness is difficult for hindering hand when opening lock.Because this lock is to design according to client's psychology requirement at present, therefore, the bicycle lock that it has solved present use is easily by sledge, the problem dialled, so this bicycle lock is the elite of widely collecting various locks, having higher use value, is the desirable anti-lock of usurping of client.
