Description

Technical Field

[0001] This utility model belongs to the field of bolt technology, specifically relating to an anti-theft bolt for wheel hubs. Background Technology

[0002] Bolt: A mechanical part, a cylindrical threaded fastener used with a nut. It consists of a head and a shank (a cylinder with external threads), and is used to fasten two parts with through holes. This type of connection is called a bolted connection. Since the two parts can be separated by unscrewing the nut, a bolted connection is a detachable connection.

[0003] Bolts are very common in daily life, from small household appliances to large spacecraft and airplanes. There are also many types of bolts. According to the head shape, they can be divided into hexagonal head bolts, square head bolts, round head bolts, and countersunk head bolts; according to the use, they can be divided into anchor bolts, U-bolts, and double-ended bolts; and according to the performance grade, they can be divided into high-strength bolts and ordinary bolts, etc.

[0004] Wheel bolts are essential components that fasten car wheels and tires to a vehicle, ensuring its safe and proper operation. They possess advantages such as high strength, high torque resistance, corrosion resistance, and light weight. However, in reality, some unscrupulous individuals remove wheel bolts and then dismantle the wheels and tires to sell for illicit profit. This poses a significant safety hazard and causes substantial property damage to car owners, and such incidents are not uncommon. Utility Model Content

[0025] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0026] like Figure 1 , 2 The diagram shows the structure of the anti-theft bolt for wheel hubs according to this utility model. The anti-theft bolt includes a bolt head 1, a bolt middle portion 2, and a bolt tail portion 3. The bolt head 1 is integrally connected to one side of the bolt middle portion 2, and the diameter of the bolt head 1 is smaller than the diameter of the bolt middle portion 2. When using a socket wrench for corresponding operations (such as tightening or loosening the bolt), the socket wrench is inserted into the bolt head 1 and abuts against the side of the bolt middle portion 2, thereby limiting the position of the socket wrench and making operation more convenient.

[0027] The bolt tail 3 is integrally connected to the other side of the bolt middle part 2 (i.e., the bolt head 1 and the bolt tail 3 are located on both sides of the bolt middle part 2), and the diameter of the bolt tail 3 is smaller than the diameter of the bolt middle part 2. When the operator screws the bolt into the car's wheel hub, it should be done until the side wall of the wheel hub abuts against the bolt middle part 2. The bolt tail 3 is limited in the part screwed into the wheel hub to prevent over-tightening and excessive tightening, which would make subsequent disassembly and maintenance inconvenient.

[0028] like Figure 1 As shown, the inner guide portion 4 is inclinedly disposed on the side of the bolt tail portion 3 away from the bolt middle portion 2. When screwed into the threaded hole of the hub, it guides the screwed-in bolt tail portion 3, facilitating bolt installation. The external thread 5 is disposed on the outer circumferential surface of the thread tail portion and mates with the threaded hole on the hub.

[0029] The first adapter 6 is inclinedly disposed on the side of the middle part 2 of the bolt near the head 1 of the bolt. The first adapter 6 cooperates with the inner wall of the socket wrench. When the socket wrench is inserted into the head 1 of the bolt, the inner wall of the socket wrench abuts against the first adapter 6, thereby limiting the position of the socket wrench and making it more convenient to operate.

[0030] The second adapter 7 is located on the side of the bolt middle portion 2 near the bolt tail portion 3. The second adapter 7 is arc-shaped with its center facing the bolt middle portion 2. An arc-shaped portion that mates with the second adapter 7 is provided on the outer side of the threaded hole on the hub. When the bolt is tightened to the correct position, the second adapter 7 abuts against the arc-shaped portion on the outer side of the threaded hole on the hub. By providing the arc-shaped second adapter 7, the contact area with the hub surface is increased, friction is improved, and bolt loosening is prevented.

[0031] The first outer guide portion 8 is inclinedly disposed on the side of the bolt head 1 away from the bolt middle portion 2. The first outer guide portion 8 is used to guide the inserted socket wrench, facilitating the insertion of the socket wrench into the bolt head 1. There are multiple retaining strips, integrally ring-shaped on the outer circumference of the bolt head 1, and the number of retaining strips is odd. Because the number of inner slots of the socket wrench corresponding to an odd number of retaining strips is also odd, the price of an odd-numbered socket wrench is higher than that of an even-numbered socket wrench. This is due to the higher production difficulty and cost of odd-numbered socket wrenches, thus providing stronger anti-theft protection.

[0032] The angles between two adjacent buckles are not exactly the same, so the bolt head 1 uses an irregular plum blossom drive groove, which requires the use of customized matching tools for disassembly and assembly. This is used to fix the wheel hub while preventing the wheel hub from being stolen.

[0033] like Figure 2 As shown, the abutment portion 17 is inclinedly arranged on both sides of the retaining strip, and the width of the retaining strip gradually decreases from the center of the bolt head 1 outwards, that is, the width of the retaining strip on the side closer to the bolt head 1 is greater than the width of the retaining strip on the side farther away from the bolt head 1. When the operator uses a special socket wrench to disassemble, the wider width at the base of the retaining strip results in higher structural strength, preventing the retaining strip from breaking under force.

[0034] An inclined second outer guide portion 16 is provided on the side of the retaining strip away from the middle part 2 of the bolt. The second outer guide portion 16 is used to guide the inserted socket wrench, so as to facilitate the insertion of the socket wrench into the retaining strip of the bolt head 1.

[0035] like Figure 2 As shown, in this embodiment, there are seven fasteners, arranged clockwise as follows: first fastener 9, second fastener 10, third fastener 11, fourth fastener 12, fifth fastener 13, sixth fastener 14, and seventh fastener 15. The angle between the first fastener 9 and the second fastener 10 is 50°, the angle between the second fastener 10 and the third fastener 11 is 50°, the angle between the third fastener 11 and the fourth fastener 12 is 39°, the angle between the fourth fastener 12 and the fifth fastener 13 is 66°, the angle between the fifth fastener 13 and the sixth fastener 14 is 50°, the angle between the sixth fastener 14 and the seventh fastener 15 is 39°, and the angle between the seventh fastener 15 and the first fastener 9 is 66°.

[0036] Bolt head 1 features an irregular perforated drive groove, requiring custom-made tools for disassembly and assembly. This serves to secure the wheel hub while preventing its theft.

[0037] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
