The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1-6, the present invention provides an embodiment: a disc brake lock comprises a lock body 2, wherein a lock core 5 and a main pin 3 are arranged on the lock body 2, and a locking piece 16 is arranged between the main pin 3 and the lock core 5; the lock core 5 drives the locking piece 16 to slide, so that the main pin 3 can be inserted into the lock block 18 or pulled out of the lock block 18; through the above manner, the normal opening and closing, and the specific opening and closing actions of the lock body 2 are realized, which are consistent with the prior art scheme, and therefore, the excessive description is not repeated here.

The pressure-bearing container 17 is fixed at the bottom of the lock body 2 through the base 4; a pressing plate 15 is abutted against the locking sheet 16 through the pressure-bearing container 17, and the pressing plate 15 is connected with a sliding block 13 arranged on the locking sheet 16; through the mode, the pressing plate 15 is arranged at the bottom of the locking sheet 16, and when the pressure-bearing container 2 is normally opened and closed, the pressing plate 15 is abutted to the lower side of the locking sheet 16 under the pressure of the pressure-bearing container 17, so that the pressing plate 15 and the locking sheet 16 synchronously slide, and the device is normally opened and closed.

However, when the pressure-bearing container 17 loses pressure, the pressure plate 15 moves toward the base 4 under the action of the first elastic member 14, so as to drive the sliding block 13 to slide toward the lock cylinder 5, so that the lock pin 10 arranged inside the lock block 18 is pushed out under the action of the second elastic member 11, so as to limit the separation of the locking piece 16 from the main pin 3, at this time, the locking piece 16 is clamped by the lock pin 10, so that the locking piece 16 is difficult to slide, the main pin 3 is firmly pressed against the lock block 18, and the lock body 2 is difficult to open, thereby realizing the anti-theft function.

In addition, the first elastic member 14 and the second elastic member 11 may be made of elastic material, such as a spring. Wherein, one end of the first elastic member 14 is connected with the base 4, the other end can contact with the lock body 2, and one end of the second elastic member 11 far away from the lock pin 10 is fixed on the base 4.

In order to further improve the anti-theft performance of the device, the pressure-bearing container 17 is completely wrapped on the outer side of the lock body 2, so that the pressure plate 15 can slide on the locking sheet 16 when any place of the pressure-bearing container 17 is damaged, the main pin 3 is locked, and the device has the advantages of rapidness, comprehensiveness and reliability when the anti-theft function is started.

Preferably, the pressure container 17 is made of a flexible material, such as an air bag, so that the installation and layout of the pressure container 17 are facilitated.

Furthermore, the pressure-bearing container 17 is filled with gas or liquid, so that the internal pressure of the pressure-bearing container 17 can be easily and conveniently obtained, and the pressure inside the pressure-bearing container can be conveniently filled.

In conclusion, the outer layer of the lock body 2 is wrapped by the pressure-bearing container 17, and any place of the lock is damaged, so that the pressure-bearing container 17 leaks air, the air pressure is reduced, the pressure plate 15 is driven to slide, the lock pin 10 is ejected out, the main pin 3 is locked, and the main pin 3 is firmly riveted on a brake disc like a rivet, so that the anti-theft performance of the device is further improved.

In addition, compared with other locks which only insert the main pin into the disc hole, the device uses the locking piece 16 to rivet the main pin 3 on the brake disc after the main pin 3 passes through the disc hole; therefore, the device has better anti-theft performance than other locks of the same type.

Because the pressure plate 15 is provided with the guide piece 19 to guide the sliding block 13 to slide on the locking piece 16, when the pressure plate 15 moves downwards, the guide piece 19 drives the sliding block 13 to move towards the direction of the lock cylinder 5, and therefore, the sliding block 13 is further ensured to slide stably.

Furthermore, the locking piece 16 is further provided with a sliding groove 20 for the sliding of the sliding block 13, when the sliding block 13 slides, the sliding groove 20 can guide the sliding block 13 to slide stably, and the sliding groove 20 is free from being blocked, so that the locking piece 16 is positioned by the locking pin 10 passing through the sliding groove 20.

In order to ensure that the locking sheet 16 can not slide when being attached to the main pin 3, the locking sheet 16 abuts against the arc groove 9 formed in the main pin 3 through the toothed plate 12, so as to limit the main pin 3 from being drawn out of the locking block 18, and after the toothed plate 12 is easily adapted to the arc groove 9, the main pin 3 can be further prevented from sliding upwards, so that the main pin 3 is further limited in the locking block 18; at this time, the problem that the kingpin 3 is difficult to be positioned because the kingpin 3 is easy to slide upwards without the arc groove 9 can be solved.

Because the lock body 2 is arranged in the shell 1 and the lock body 2 is fixed in the shell 1 through the base 4, the lock body 2 is protected on one hand, and the pressure-bearing container 17 is protected on the other hand.

Further, the pressure-bearing container 17 is filled in the space enclosed by the base 4, the shell 1 and the lock body 2;

in addition, as shown in fig. 6, in order to keep the pressure inside the pressure-bearing container 17 constant all the time, a cavity 23 is provided on the lock body 2, a push plate 22 is provided in the cavity 23, the push plate 22 is connected to the cavity 23 through a third elastic member 21 provided, and the pressure-bearing container 17 inside the cavity 23 is pressed by the push plate 22 under the action of the third elastic member 21, so that the pressure inside the pressure-bearing container 17 is constant.

As described above, since the entire lock body 2 is protected by the pressure container 17 and the housing 1, other parts than the main pin 3 and the like can be processed from a plastic material. Thus reducing the production cost of the lock and the overall weight of the lock.

In order to solve the problem that the anti-theft performance of the device is reduced due to the fact that the reserved space of the lock hole 7 is too large, the shell 1 is further provided with the lock hole 7; the lock hole 7 is used for guiding a key 8 arranged in the lock hole to be connected with the lock cylinder 5, the shell 1 is further provided with a guide groove 6 linked with the lock hole 7, and the key 8 is guided to enter the lock hole 7 through the guide groove 6.

Through the scheme, firstly, the key 8 is transversely cut into along the guide groove 6 and then is translated to the lock hole 7, and the key 8 is pushed into the lock hole 7, so that the structure of the guide groove 6 limits that an unlocking tool cannot directly enter the lock hole 7, the operation space and the contact range of the unlocking tool are also limited, the unlocking tool cannot be used, and the anti-theft performance of the device is further improved.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
