Detailed description of the invention
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's statement.
Embodiment
As shown in Fig. 1,2,3,4,5,6,7,8, a kind of automobile spare tire Anti-theft-dismounting device, comprise key joint 1, lock tube 2 and lock core shaft 4, described key joint 1 is provided with special-section key disc 11, locating disk 12 and drive link 13 vertically in turn, described lock tube 2 is provided with vertically in turn same shape the first profiled holes 21 and between the second profiled holes 22, first profiled holes 21 and the second profiled holes 22 along the dislocation that axis rotary is angled; Described lock core shaft 4 is provided with claw 41, described special-section key disc 11 is provided with locating notch 14, described locating notch 14 matches with claw 41, and the shape of described special-section key disc 11 matches with the first profiled holes 21 and the second profiled holes 22; When special-section key disc 11 engages with lock core shaft 4 through the second profiled holes 22, described locating disk 12 passes the first profiled holes 21 and is blocked on the front end face of the second profiled holes 22.
In the present invention, in order to realize the support to lock core shaft 4, described key joint 1 is sleeved in support sleeve 3, has the degree of freedom be rotated about axis between key joint 1 and support sleeve 3, and described lock tube 2 is fixedly mounted on support sleeve 3.
Stability stressed during in order to ensure that lock core shaft 4 rotates, avoids lock core shaft 4 and key joint 1 to thread off or stuck, and described claw 41 has two, and two claw 41 Central Symmetries are arranged on the outer wall of lock core shaft 4.
Key joint 1 can be driven in the present invention in several ways to rotate, such as described drive link 13 is hexagon bar, utilizing hex spanner to rotate key joint 1 drives lock core shaft 4 to rotate, again such as, described drive link 13 is provided with inner hexagonal hole, rotates key joint 1 by the hexagonal bar of L shape and drive lock core shaft 4 to rotate; No matter use which kind of rotating manner, all can not exceed the claimed scope of the claims in the present invention.
In the present embodiment, described special-section key disc 11 is combined by two fanning strips and a circular piece, two described fanning strip Central Symmetries are arranged on the outer rim of circular piece, gap between two fanning strips forms a pair locating notch 14, locating notch 14 is stuck on claw 41, when key joint 1 rotates, drive lock core shaft 4 to rotate by claw 41 with engaging of locating notch 14, realize unblanking.
In addition, in the present invention, because the rotating torque required for lock core shaft 4 is larger, and need to rotate the operation that tens of circle could realize unblanking, in order to the stability of rotating can be ensured, dislocation angle between described first profiled holes 21 and the second profiled holes 22 is 90 °, described special-section key disc 11 is identical with the shape of locating disk 12, both rotate about the axis shape error angle in 90 °, like this when special-section key disc 11 is by the first profiled holes 21, half-twist is by the second profiled holes 22 again, now locating disk 12 can pass the first profiled holes 21 just, when special-section key disc 11 moves on and locating notch 14 is engaged on claw 41, locating disk 12 is fitted on the front end face of the second profiled holes 22 by the second profiled holes 22 stop, realize the location to special-section key disc 11 axial location.
