Problems solved by technology

[0002] With the rapid development of the automobile industry, a large number of automobiles have increased. Many automobiles are often parked in the open air because of no garages, and accidents of car tires being stolen occur from time to time; Nut", announcement number: CN2265916Y, it is to set a round hole at the end of the hexagonal bolt or nut, there are multiple ring grooves on the inner wall of the hole, the leaf lock cylinder is installed in the round hole, and the multiple leaves and rings of the lock cylinder The grooves correspond to fit, and the hexagonal bolt or nut is equipped with a barrel-shaped and slidingly fitted cover, and the concave platform at the outer end of the cover is matched with the convex platform at the upper end of the lock cylinder; although this structure can also prevent the bolt from opening when it is installed on the screw, It is not feasible to drill a hole on the nut, and the strength of the nut will be damaged, and it is very troublesome to install the lock cylinder and prepare the key

Embodiment 1

[0018] Shown in Fig. 1-Fig. 4, a kind of automobile tire anti-theft bolt of the present invention comprises screw 1 and nut 2, is characterized in that connects growth segment 3 on the original screw, is about to increase the screw front end, and the diameter of growth segment is littler than screw, A code lock is set on the growth section; said code lock is provided with two protrusions 301 on the periphery of the growth section; in addition, there is a buckle 4 matching the number of the protrusions, and the outer circumference of the buckle 4 The diameter is larger than the diameter of the screw, and numbers or letters are marked on the outer circumference. The numbers and letters form a password. The inner hole 401 matches the diameter of the growth section, and can rotate and move relative to the growth section, and is connected to the inner hole 401. The slot 402 of the slot 402 is matched with the protrusion 301 of the growth section; there is a casing 5 on the periphery...

Embodiment 2

[0020] As shown in Figures 5-8, a ring 7 is placed between the two buckles 4 in Example 1, the radius of the inner hole of the ring is greater than the distance from the axis of the growth section to the raised end face; its outer diameter is the same as that of the buckle Ring 4 has the same outer diameter; the rest repeat Example 1.

[0021] In the above-mentioned embodiment, the slot 6 on the casing 5 can extend to one side of the casing to the end face of the casing, so as to facilitate the insertion of the clasp;

[0022] The slot 6 on the casing 5 may not extend to the end surface of the casing. When assembling, put the buckle ring 4 and the circular ring 7 into the casing barrel, and then weld the end surface at the seam 501 to fix it;

[0023] The hole through the growth section provided on one end face of the casing includes an inner hole 502 matching the diameter of the growth section and a slot 503 connected with the inner hole 502 and matching with the protrusion 3...
