Abstract

The utility model relates to a theft-proof lock for a motorcycle, which comprises a lock sleeve and a U-shaped lock bolt. The lock sleeve is made of a metal round pipe, and a pipe body of the lock sleeve is provided with two holes which are in the same direction; both ends of the U-shaped lock bolt can be simultaneously inserted into the holes on the pipe body of the lock sleeve; both ends of the U-shaped lock bolt are respectively provided with a latch hole, and the directions of the two latch holes are mutually perpendicular; one end near a lock head can be inserted and fixed by a latch of the lock head, and the other end is fixed by a horizontal latch. The U-shaped lock bolt of the utility model can be fastened in the holes on the pipe body of the lock sleeve; as a latch structure is used, the U-shaped lock bolt and the lock sleeve can not be separated through a knocking method outside a pipe; the lock head uses a special structure that the lock head and a guide sleeve are combined, and accordingly, the design has strong theft-proof effect.

Description

Anti-theft lock for motorcycle

The utility model belongs to a kind of anti-theft lock for motorcycle.

Anti-theft lock for motorcycle great majority on the market are spring lock structure at present, wherein the U-shaped locking bolt with mostly be bayonet socket being connected of lock tube and connect, the car thief knocks and shape locking bolt and lock tube can be separated with iron hammer, and the tapered end on the common in addition lock body also is easy to by iron hammer shake pine, knocks out; That is to say that present anti-theft lock for motorcycle on the market is not because on the self structure, great majority all possess good anti-theft effect, as patent 95205576.7 multifunctional motorcycle theftproof locks.

The purpose of this utility model is to provide one and the novel structure uniqueness, and theftproof performance is good, can't destroy the anti-theft lock for motorcycle of its structure with iron hammer.

The purpose of this utility model is to realize like this, construct a kind of anti-theft lock for motorcycle, comprise lock tube and U-shaped locking bolt, lock tube is made by metal circular tube, one end blind plate sealing, the other end has tapered end, it is characterized in that: the pipe shaft of lock tube has two equidirectional holes, its diameter is than the slightly larger in diameter at the two ends of U-shaped locking bolt, and the two ends of U-shaped locking bolt can be inserted on the lock tube pipe shaft in the hole simultaneously; U-shaped locking bolt two ends all have pin hole, and two pin hole directions are orthogonal, can be fixing near an end of tapered end by the insertion of tapered end lock bolt, and the other end is fixed by a horizontal latch; The U-shaped locking bolt can be that fulcrum is done 360 degree rotations with the other end near after extracting the hole of an end from the lock tube pipe shaft of tapered end; Lock bolt and lead all are fastened on the internal lock stamen, connect spring advance and retreat and rotation with internal lock stamen, external lock stamen, pellet shot from a slingshot cover, have L shaped groove on the fairlead, and lead is by the track advance and retreat of L shaped groove; Pellet shot from a slingshot and little spring check key are used.

U-shaped locking bolt of the present utility model can be fastened in the pipe shaft hole of lock tube, owing to adopted the latch structure of structure uniqueness, can't separate U-shaped locking bolt and lock tube with the method for knocking outside pipe; And tapered end has adopted special tapered end and fairlead structure combining, thereby makes the design have extremely strong anti-theft effect.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model structure sectional view;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is user mode figure of the present utility model;

Fig. 4 is that of the present utility model another just used state diagram.

As shown in Figure 1, lock tube 2 is made by metal circular tube, and an end is with blind plate 3 sealings, and the other end has tapered end, and the pipe shaft of lock tube has two equidirectional holes, and its diameter is than the slightly larger in diameter at the two ends of U-shaped locking bolt 4, and the two ends of U-shaped locking bolt 4 can be inserted on the lock tube pipe shaft in the hole; U-shaped locking bolt 4 two ends all have pin hole, and two pin hole directions are orthogonal, can be fixing near an end of tapered end by 5 insertions of tapered end lock bolt, and the other end is fixed by a horizontal latch 1; U-shaped locking bolt 4 can be 360 rotations of fulcrum degree of work with the other end near after extracting the hole of an end from lock tube 2 pipe shafts of tapered end; Lock bolt 5 and lead 9 all are fastened on the internal lock stamen 11, connect springs 7 with internal lock stamen 11, external lock stamen 8, pellet shot from a slingshot cover 10 and advance and retreat and rotate.As shown in Figure 2, have L shaped groove on the fairlead 6, lead 9 is by the track advance and retreat of L shaped groove.

As shown in Figure 3 and Figure 4, the state diagram when Fig. 3 locks for the utility model, at this moment horizontal latch 1 direction is parallel with blind plate 3 directions, also horizontal latch can't be taken out from pin hole even destroy blind plate.State diagram when Fig. 4 opens for the utility model, the at this moment horizontal 1 pin direction of inserting is vertical with blind plate 3 directions, when concrete the use, key is inserted in the lockhole, touch forward, pull about 30 degree more clockwise, lock bolt 5 withdraws under the active force of spring with internal lock stamen 11, external lock stamen 8, pellet shot from a slingshot cover 10, lock is opened, the movable end of U-shaped locking bolt 4 is passed wheel, insert in the hole of lock tube, push away key toward in hand, another mistake hour hands key can be locked firm motorcycle approximately.
