[detailed description of the invention]
Below in conjunction with the accompanying drawings the technology of the present invention feature is described in further detail so that described skilled person manages
Solve.
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
Being equipped with one group of three grades of hole 2, described three grades of holes 2 include aperture 201, mesopore 202 and macropore 203 from bottom to up, and its aperture is successively
Become big, in described three grades of holes 2, be provided with mobilizable movable pellet 8.Additionally, the application goes back 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 grades of holes 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 grades of holes 2, thus playing the effect unblanked, this antitheft key
The principle that spoon is unblanked refers to the patent of invention applied for before.
Anti-theft key as above, is provided with annular groove 804, at described annular groove at described movable pellet 8 outer wall
The snap ring 3 that can prevent described movable pellet 8 from completely disengaging from described movable marble hole 2 it is cased with on 804, intrinsic pressure at described macropore 203
Tightly having back-up ring 4, that end that described back-up ring 4 is pressed into macropore 203 is provided with for described snap ring 3 is locked at described mesopore 202
Wedge-shaped part, it is interior or concordant with macropore 203 end face that the other end is pressed into macropore 203.
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 movable pellet 8 is less than or equal to the thickness of described key body 1,
Make movable pellet 8 coordinate alterable with the pellet height that links in lock core, increase secret key amount, increase anti-dial, prevent technical opening
The difficulty opened.
Anti-theft key as above, described movable pellet 8 includes the taper marble head 801 being located at two ends and connects two
The connection post 802 of individual described taper marble head 801, the external diameter of described taper marble head 801 is more than the external diameter of described connection post 802
To form described annular groove 804.The two ends of this activity pellet 8 are processed to oblique angle plane.
