Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, and more specifically, the utility model relates to a new type of anti-theft bolt for vehicle wheels.

Background Art

[0002] A bolt is a part used to fasten two components. The bolt can be used in combination with a nut to complete the fastening work, and at the same time, the bolt can complete the fastening work alone. For example, one component is provided with a through hole, and the other component is provided with a threaded hole corresponding to the through hole. The bolt passes through the through hole and is screwed into the threaded hole to complete the fastening of the two components.

[0003] There is a prior art titanium alloy anti-theft bolt for automobile wheels, with the publication number CN 217029604 U. The bolt has a threaded portion and a bolt head for cooperating with a tool to fasten or disassemble the bolt. The bolt head is a polygonal structure with an odd number of sides greater than two, and an auxiliary portion for assisting the operation of the tool cooperating with the bolt head is provided on the bolt head. This kind of utility model adopts a bolt head with an odd-polygon structure to achieve the anti-theft effect. However, since the odd-polygon bolt head requires a matching auxiliary block for installation and disassembly, due to the eccentric moment during use, it is easy to shift and misalign during installation and disassembly, resulting in inconvenient use and personal injury, affecting the use of the bolt.

[0004] In order to overcome the above-mentioned defects of the prior art, the purpose of the present utility model is to provide a new type of anti-theft bolt for vehicle wheels, which has the characteristics of stable earthquake resistance, good sealing performance, and is not easily disassembled by humans.

[0005] To achieve the above purpose, the present utility model provides the following technical solution: A new type of anti-theft bolt for vehicle wheels includes a bolt head, a screw rod portion, a fixing piece, and a rotating insertion block. The rotating insertion block is inserted into the top of the bolt head, and a fixing piece is provided below the bolt head. The fixing piece is fixedly connected to the screw rod portion downward.

[0006] Preferably, the bolt head includes a bolt head, a top block, rotating teeth, and a rotating insertion hole. The bolt head is circular, a top block is provided above the bolt head, the cross-section of the top block is circular, rotating teeth are evenly provided on the outside of the top block, and the rotating insertion hole is vertically arranged inside the top block and the bolt head.

[0007] Preferably, the bolt head is integrally formed.

[0008] Preferably, the screw rod portion includes a threaded section and a screw neck section. The screw neck section is welded to the fixing piece above, the screw neck section is connected to the threaded section downward, and external threads are evenly provided on the outside of the threaded section.

[0009] Preferably, a limiting block is provided on the screw neck section.

[0010] Preferably, locking teeth are provided below the fixing piece. The fixing piece is fixedly connected to the bottom of the screw head upward through a connecting section. The diameter of the connecting section is smaller than that of the fixing piece, and a sealing ring is provided outside the connecting section.

[0011] Preferably, the sealing ring is made of rubber material.

[0012] Preferably, the rotary insert block includes an insert block body, a connecting groove, and an inner convex block.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. A new type of vehicle wheel anti-theft bolt of the present utility model uses a circular screw head and a top block to prevent manual disassembly and replacement. During installation and disassembly, a rotary insert block is used, and a wrench is used for disassembly and assembly. The connection between the insert block and the screw head is increased through the rotary teeth and the insertion hole, which can better perform operations and improve the use efficiency.

[0016] 2. A new type of vehicle wheel anti-theft bolt of the present utility model improves the overall sealing degree of the bolt through the sealing ring provided above the fixing piece, prevents the inside of the bolt from being eroded, and extends the service life of the bolt.

Specific Embodiment

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Refer to Figures 1-3 , in the embodiment of the present invention, a new type of vehicle wheel anti-theft bolt is characterized by including a screw head part 1, a screw rod part 2, a fixing piece 3, and a rotating insertion block 4. The screw head part 1 is integrally formed. The screw head part 1 includes a screw head 11, a top block 12, a rotating tooth 13, and a rotating socket 14. The screw head 11 is circular, and a top block 12 is provided above the screw head 11. The cross-section of the top block 12 is circular, and rotating teeth 13 are evenly provided on the outside of the top block 12. The rotating socket 14 is vertically arranged inside the top block 12 and the screw head 11. The top of the screw head part 1 is inserted with the rotating insertion block 4. The rotating insertion block 4 includes an insertion block body 41, a connecting groove 42, and an inner convex block 43. The insertion block body 41 is hexagonal, and a connecting groove 42 is provided inside the insertion block body 41. A plurality of downwardly protruding inner convex blocks 43 are provided in the connecting groove 42. The connecting groove 42 is adapted to the top block 12 at the top of the screw head part 1. The inner convex blocks 43 are inserted into the rotating socket 14. A fixing piece 3 is provided below the screw head part 1. Locking teeth 31 are provided below the fixing piece 3. The fixing piece 3 is fixedly connected to the bottom of the screw head part 1 upward through a connecting section 32. The diameter of the connecting section 32 is smaller than the diameter of the fixing piece 3. A rubber sealing ring 33 is provided outside the connecting section 32. The fixing piece 3 is fixedly connected to the screw rod part 2 downward. The screw rod part 2 includes a threaded section 21 and a screw neck section 22. The screw neck section 22 is welded and connected to the fixing piece 3 above. A limiting block is provided on the screw neck section 22. The screw neck section 22 is connected to the threaded section 21 downward. External threads are evenly provided on the outside of the threaded section 21.

[0024] Working principle:

[0025] When the novel vehicle wheel anti-theft bolt of the utility model is in use, first insert the convex block 43 of the rotary insert block 4 into the rotary jack 14 so that the top block 12 is inside the connecting groove 42. At this time, the rotary teeth 13 outside the top block 12 are clamped in the connecting groove 42 for fixed connection. Then install the bolt into the wheel hub bolt hole with a wrench. Since there is a limiting block at the neck section 22, the connection and sealing performance of the connection can be strengthened. After installation, the bottom of the fixing piece 3 is closely attached to the connection surface, and the locking teeth 31 at the bottom of the fixing piece 3 provide friction to prevent the bolt from falling off during vibration. The provided sealing ring 33 prevents the bolt connection from being eroded, improving the overall safety of the bolt in use. After installation, remove the rotary insert block 4. In the absence of the rotary insert block 4, it is difficult for the circular top block 12 and the bolt head 11 to be manually disassembled, improving its anti-theft performance.

[0026] The above embodiments are illustrative of the present utility model and not restrictive thereof. Any simple transformation of the present utility model falls within the protection scope of the present utility model.
