Description

Technical Field

[0001] This utility model relates to the field of bolt technology, and in particular to a hexagonal head bolt assembly. Background Technology

[0002] A bolt is a mechanical part, a cylindrical threaded fastener that is fitted with a nut. It consists of a head and a shank (a cylinder with external threads). It is used to fasten two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated. Therefore, a bolted connection is a detachable connection. Hexagonal head bolts are one type. To give bolts a certain degree of wear resistance, they are often made of stainless steel.

[0003] In existing high wear-resistant hexagonal head bolts, the cross groove at the top is often directly exposed. As a result, the cross groove is prone to rusting during long-term use, which can cause slippage during disassembly and make it difficult for users to remove the bolt.

[0004] Therefore, it is necessary to provide a hexagonal head bolt assembly to solve the above-mentioned technical problems. Utility Model Content

[0023] Furthermore, the terms used below are defined based on the functions of this utility model and may vary depending on the user's or operator's intent or convention. Therefore, these terms are defined based on the entire contents of this specification.

[0024] like Figures 1 to 5As shown, a hexagonal head bolt assembly includes a bolt body 1 and a cap 2. The cap 2 is threaded into the side wall of the bolt body 1. The bolt body 1 includes a bolt head 101 and a screw 102. The bolt head 101 has a regular hexagonal structure. The screw 102 is located in the middle of the side wall of the bolt head 101. A first threaded portion 103 is formed on the outer circumference of the screw 102. The first threaded portion 103 passes through the component and engages with a nut to lock the component onto the vehicle. A truncated cone 104 is provided on the side wall of the bolt head 101. A threaded hole 105 is formed in the middle of the side wall of the truncated cone 104. A groove 106 is provided at the bottom center of the threaded hole 105. The groove 106 has a cross-shaped structure and is used to engage a screwdriver to rotate and tighten the bolt to the corresponding position of the automotive part for locking and fixing. A slot 107 is provided at the bottom of the threaded hole 105. The slot 107 has an annular structure and a sealing ring 3 is provided in the slot 107. A second threaded part 201 is provided on the side wall of the cover 2. The second threaded part 201 is threadedly connected to the threaded hole 105, and the side wall of the cover 2 abuts against the surface of the sealing ring 3, thereby sealing the connection between the cover 2 and the bolt body 1.

[0025] like Figure 2 and Figure 5 As shown, a boss 202 is provided on the side wall of the cover 2 away from the second threaded portion 201. The boss 202 has a square structure. A first groove 203 is formed on the side wall of the boss 202. A through hole 204 is formed at the middle of the bottom of the first groove 203. The through hole 204 penetrates the cover 2. A second groove 205 is formed on the inner wall of the through hole 204. A rubber sheet 4 is engaged in the second groove 205, and the rubber sheet 4 closes the through hole 204. Four grooves 401 are formed in the center of the rubber sheet 4, which divide the center of the rubber sheet 4 into four fan-shaped pieces. The centers of the four fan-shaped pieces are in contact with each other and spliced ​​together. A third groove 207 is formed on one side of the bottom of the first groove 203. Mounting holes 2 are formed on the side wall of the third groove 207 at the opposite positions. 08. A rotating shaft 6 is provided in the mounting hole 208, and a waterproof cover 5 is rotatably provided in the third groove 207. The waterproof cover 5 is made of soft material and has a circular structure. The lower end of the waterproof cover 5 is engaged in the through hole 204, thereby sealing the upper end of the through hole 204. A protrusion 501 is provided on the outer circumference of the waterproof cover 5. The side wall of the protrusion 501 has a hole for the rotating shaft 6 to pass through. An operating ear 502 is also provided on the outer circumference of the waterproof cover 5. The operating ear 502 is positioned opposite the protrusion 501. When it is necessary to insert a tool into the groove 106 to rotate the bolt body 1, the waterproof cover 5 is pulled out from the through hole 204 through the operating ear 502. Then, the tool is inserted into the through hole 204, and the tool head pushes open the center of the rubber sheet 4 and penetrates into the groove 106 for operation.

[0026] A rotating hole 206 is provided at the position opposite to the side wall of the protrusion 202 of the cover 2, and a wristband 7 is rotatably installed in the rotating hole 206.

[0027] Specifically, the first threaded portion 103 passes through the component and engages with the nut to lock the component onto the vehicle. The second threaded portion 201 of the cover 2 is screwed into the threaded hole 105, causing the side wall of the cover 2 to abut against the sealing ring 3. This firmly presses and fixes the sealing ring 3 in the slot 107, sealing the connection between the cover 2 and the bolt body 1. This prevents external liquid from flowing into the groove 106 through the threaded hole 105 and causing corrosion, resulting in a good waterproof sealing effect. Furthermore, the waterproof cap 5 is secured in the first groove 203 and through hole 204 of the cover 2. To further prevent external liquids from entering the groove 106 and causing corrosion, thus avoiding affecting the tool's fit with the groove 106 to adjust the bolt body 1, and thus extending the service life of the bolt body 1, a rubber sheet 4 is set in the second groove 205 of the cover 2. This can prevent external liquids from flowing into the groove 106 due to the waterproof cover 5 not being closed tightly, and will not affect the tool's ability to penetrate into the groove 106 to adjust the bolt body 1. A hand ring 7 is rotated on the side wall of the boss 202, which can easily install and remove the cover 2. The installation and removal are convenient and quick.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
