The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is carried out detailed description.

As shown in Figure 1, be the structural representation of the utility model wolf's fang theftproof lock, it comprises: lock body 1 and lock core 2; Said lock core 2 is located in the lock body 1; Double many springs 11 are arranged at said lock body 1 top, are provided with double shell hole below the spring 11, are provided with the double pellet shot from a slingshot 12 of lock body in the shell hole; Said lock core 2 is divided into row through keyhole slots and arranges down; Last row and following row also are provided with double shell hole; The double pellet shot from a slingshot 21 of the row of being provided with and the double pellet shot from a slingshot of arranging down 22 in the double shell hole; Row's double shell hole is corresponding with the double shell hole on lock body 1 top on the said lock core 2, and the double pellet shot from a slingshot of arranging on the double pellet shot from a slingshot on while lock body 1 top and the lock core 21 is corresponding.

Like Fig. 3 and shown in Figure 4; Key structure sketch map for the utility model wolf's fang theftproof lock; Said key 3 is provided with a plurality of trapezoidal holes 31; The back side is respectively equipped with a plurality of deep mixed tubaeform grooves 32, and the double pellet shot from a slingshot 21 with last row is corresponding with two pellets shot from a slingshot 22 positions of arranging down respectively with groove 32 for through hole 31.

The double pellet shot from a slingshot 21 of the said row of going up is provided with a plurality of long marbles 221; When key inserted keyhole slots, long marble 221 passed trapezoidal hole 31 on the key under 11 effects of lock body upper springs; Insert the keyhole slots bottom always, prevent that unlocking tool from inserting keyhole slots and having the suburb to open.

As shown in Figure 2, the shape of said row's double pellet shot from a slingshot 22 down is corresponding with groove 32, different in size, and an end is cylinder and cone, and overhead is in lock core 2 bottoms, and the other end is a cone, is located on the keyhole slots.

The double pellet shot from a slingshot hole of said lock body 1 bottom is less than 2 times rows' of lock core double pellet shot from a slingshot; Because row's double pellet shot from a slingshot 22 is different in size down; Long pellet shot from a slingshot is that cone is cylinder with short pellet shot from a slingshot towards next end towards next end, and cone portion branch inserts the shell hole of lock body 1 bottom, because the shell hole of lock body bottom is not provided with spring; Cone is made arcuate movement in the lock body shell hole, lock core just can rotate.

The double pellet shot from a slingshot 21 of the row of going up of the utility model wolf's fang anti-theft lock core 2 is not when unblanking; Last row's double pellet shot from a slingshot 21 is to drop on the keyhole slots bottom; And 22 of the double pellets shot from a slingshot that lock core is arranged down expose conical part bottom keyhole slots, do not prop up keyhole slots top, help the key plug; Pellet shot from a slingshot forms S shape, favourable antitheft in keyhole slots so up and down; Lock core 2 upper and lower rows' double shell hole is staggered.When key inserted keyhole slots, if the key back side does not have deep mixed tubaeform groove 32, key 3 will be oppressed down the shell hole that row's one end is pellet shot from a slingshot 22 entering lock bodies 1 bottom of taper; At this moment key can not rotate, if the double tubaeform groove 32 at the key back side is than the tubaeform groove of normal key dark (when coincideing with following row's pellet shot from a slingshot 22), because the shell hole of lock body bottom is not provided with spring; The active force that does not have spring, key Rotate 180 degree, the double pellet shot from a slingshot hole of lock body 1 is just aimed in lock core 2 times row's double pellet shot from a slingshot hole; At this moment under the spring action; The double pellet shot from a slingshot on lock body top will insert in row's under the lock core the double shell hole, and key can not rotate, and pins automatically.

The utility model only carries out illustrative with the foregoing description; The structure of each parts, the position is set and connects and all can change to some extent; On the basis of the utility model technical scheme; All improvement and equivalents of individual component being carried out according to the utility model principle all should not got rid of outside the protection domain of the utility model.
