Beneficial effect is: by the utility model is arranged in the brake disc, can effectively motor bike be pinned, prevent that motor bike is pushed away owing to moving, and also simple in structure.

Four, description of drawings:

Fig. 1 is the utility model running condition figure;

Fig. 2 is the utility model lock opening cutaway view;

Fig. 3 opens the state cutaway view for the utility model locking;

Scheme drawing when Fig. 4 does not insert brake steel ring circular hole for lock pin of the present utility model;

Scheme drawing when Fig. 5 inserts brake steel ring circular hole for the utility model lock pin.

Five, the specific embodiment:

With reference to accompanying drawing, the utility model will be further described:

Comprise the lock body 9 that is fixed on brake disc 5 inboards, described lock body 9 is established a groove, and lock pin 10, core 4 and spring 11 are housed in the groove, and brake disc 5 is established a keyhole 8; Establish on the brake facing 6 and lock pin 10 corresponding circular holes 7; Wherein, to establish a breach corresponding with core 4 in described lock pin 10 bottoms.

Principle of work is as described below: when lock was opened, core 4 blocked lock pin 10, and lock pin 10 contracts in lock body 9, and spring 11 is in tension; When will be during locking with lock, with key 1 Rotate 180 ℃, key 1 drives core 4 Rotate 180s ℃, core 4 becomes top by the bottom in the position of blocking mutually with lock pin 10, spring 11 ejects lock body 9 (as shown in Figure 3) with lock pin 10, lock pin 10 passes the circular hole 7 of brake facing 6 among Fig. 3, extend into the circular hole 3 interior (as shown in Figure 5) of brake steel ring 2, with wheel locking, even at this moment lock pin 10 does not have and circular hole 3 alignment just, enter less than in the circular hole 3, as long as wheel rotates forward or backward slightly, lock pin 10 is under the effect of spring 11, in case align with circular hole 3, will spring in the circular hole 3 (as shown in Figure 4), guarantee the safe reliability of locking.
