【Specific embodiment】
Below in conjunction with the accompanying drawings this utility model technical characteristic is described in further detail in order to described art people
Member understands.
A kind of anti-theft key, as shown in Figures 1 to 5, includes key body 1, at least sets on described key body 1
It is equipped with one group of three-level hole 2, described three-level hole 2 includes aperture 201, mesopore 202 and macropore 203 from bottom to up, and its aperture is successively
Become big, be provided with mobilizable activity pellet 8 in described three-level hole 2.Additionally, the application goes back in the two-sided of described key body 1
It is provided with tartar hole 5, primary and secondary tartar hole 6, straight-line groove 7 and curved groove 9.Under normal circumstances, due to action of gravity, movable pellet 8
Bottom is exposed outside three-level hole 2, and when key is inserted into lock core, the bottom of movable pellet 8 is by the lower pellet top in lock core
Rise and expose the linkage pellet further jack-up lock core from the upper end in three-level hole 2, thus playing the effect of unlocking, this antitheft key
The principle that spoon is unlocked refers to the patent of invention applied for before.
Anti-theft key as above, is provided with annular groove 804 in described activity pellet 8 outer wall, in described annular groove
It is cased with the snap ring 3 that can prevent described activity pellet 8 from completely disengaging from described three-level hole 2, compressing in described macropore 203 has on 804
Back-up ring 4, that end that described back-up ring 4 is pressed into macropore 203 is provided with the wedge shape for described snap ring 3 is locked at described mesopore 202
Portion, the other end is pressed in macropore 203 or concordant with macropore 203 end face.
Anti-theft key as above, step that the two sides of described snap ring 3 is formed with mesopore 202 by aperture 201 respectively, institute
State wedge-shaped part 401 and withstand locking.
Anti-theft key as above, described annular groove 804 be respectively provided on two sides with ring-shaped step 803, described in two
The distance of ring-shaped step 803 is more than described snap ring 3 thickness.
Anti-theft key as above, the height of described activity pellet 8 is less than or equal to the thickness of described key body 1,
So that movable pellet 8 highly coordinates alterable with linkage pellet in lock core, increase secret key amount, increase is anti-dial, prevent technical opening
The difficulty opening.
