[0001] This utility model belongs to the technical field of countersunk head bolts, specifically a 100° countersunk head titanium alloy bolt with anti-slip gear groove. Background Technology

[0002] In the field of mechanical connections, facing the shortcomings of both traditional bolts and countersunk bolts, as well as the stringent requirements for components in specific fields such as aerospace and high-end electronic equipment manufacturing, and leveraging the opportunities brought by the rise of titanium alloy materials, coupled with the continuous exploration and development of anti-slip structures, an innovative anti-slip gear groove 100° small countersunk titanium alloy bolt has emerged. It aims to comprehensively overcome the limitations of traditional bolts and meet the high-precision, high-reliability connection requirements under complex working conditions and special scenarios.

[0003] Meanwhile, the patent specification with application number CN215673076U discloses a countersunk bolt that prevents loosening and expands quickly, "including a countersunk bolt and a metal sleeve, a hexagonal nut is rotatably connected to the threaded section of the countersunk bolt, and a force-bearing plate is welded to the end of the threaded section, a connecting post is welded to the end of the countersunk bolt away from the force-bearing plate, a screw is welded to the end of the connecting post away from the countersunk bolt, and a spreading end is coaxially installed on the screw and the connecting post";

[0004] In the use of conventional bolts, the tightening grooves of traditional bolt heads are simple and easily worn. Once stripping occurs, disassembly is extremely difficult, often requiring special tools or even damage to the bolt to complete the disassembly, which greatly increases maintenance and time costs. Secondly, conventional bolts are mostly made of materials such as carbon steel, which are prone to rust and corrosion in some complex and harsh environments, such as high temperature, high humidity or corrosive media, leading to a decrease in strength and affecting the stability and reliability of the connection.

[0005] Therefore, a non-slip gear groove 100° countersunk titanium alloy bolt is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a non-slip gear groove 100° countersunk titanium alloy bolt, which greatly improves the convenience of bolt maintenance, avoids the situation where the entire bolt is scrapped due to damage to the bolt head structure, and can reduce the overall weight and improve equipment performance.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a non-slip gear groove 100° countersunk titanium alloy bolt, comprising a bolt head, a screw fixedly connected to the bottom end of the bolt head, the bolt head having a 100° countersunk head structure, and the inclined surface of the bolt head having several tooth grooves, the top end of the bolt head having a circular groove, the inner surface of the circular groove having a disassembly block, the top end of the disassembly block having a tightening groove, the upper inner wall of the circular groove having an iron sheet embedded therein, and the end of the disassembly block that is in contact with the iron sheet being coated with a magnetic coating.

[0008] Preferably, four positioning blocks arranged in a circular array are fixedly connected to the outer surface of the disassembly block, and the inner surface of the circular groove is provided with positioning grooves that cooperate with the four positioning blocks.

[0009] Preferably, a plurality of the tooth grooves are arranged in a ring array.

[0010] Preferably, both the bolt head and the screw are made of titanium alloy.

[0011] Preferably, the outer surfaces of the bolt head and the screw are coated with an anti-corrosion coating, and a sealing washer is provided at the connection between the bolt head and the screw.

[0012] Preferably, a guide head is fixedly connected to the bottom end of the screw. The guide head is hemispherical, and its outer surface is treated to reduce the coefficient of friction.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a bolt head and a disassembly block, achieves convenient installation and disassembly of the disassembly block under the precise cooperation of the positioning block and the positioning groove and the adsorption force of the magnetic coating and the iron sheet. When the tightening groove is worn, the disassembly block can be easily replaced, which greatly improves the convenience of bolt maintenance and avoids the situation where the entire bolt is scrapped due to damage to the bolt head structure.

[0015] 2. This utility model uses titanium alloy for both the bolt head and the screw. In high-temperature environments, the excellent heat resistance of titanium alloy can ensure that the bolt will not soften or deform due to excessive temperature. In high-humidity or corrosive environments, its excellent corrosion resistance can effectively prevent the bolt from rusting and corroding, ensuring connection strength. At the same time, its lightweight feature can reduce the overall weight and improve the performance of some equipment or structures with strict weight requirements. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4 As shown, this utility model provides a non-slip gear groove 100° countersunk titanium alloy bolt, including a bolt head 1, a screw 2 fixedly connected to the bottom end of the bolt head 1, the bolt head 1 has a 100° countersunk head structure, and the inclined surface of the bolt head 1 is engraved with several tooth grooves 6, the top end of the bolt head 1 has a circular groove 53, the inner surface of the circular groove 53 has a disassembly block 5, the top end of the disassembly block 5 has a tightening groove 51, the upper inner wall of the circular groove 53 is embedded with an iron sheet 54, and the end of the disassembly block 5 that is in contact with the iron sheet 54 is coated with magnetic coating 56. This design allows the bolt head 1 to not only have a 100° countersunk head structure to adapt to special installation requirements, but also the tooth grooves 6 on the inclined surface can increase friction to play a non-slip role, and the disassembly block 5 is attached to the iron sheet 54 through the magnetic coating 56, which is convenient to replace when the tightening groove 51 is worn, thus extending the service life of the bolt.

[0025] Specifically, four positioning blocks 52 arranged in a ring array are fixedly connected to the outer surface of the disassembly block 5. The inner surface of the circular groove 53 is provided with positioning grooves 55 that cooperate with the four positioning blocks 52, which ensures the accuracy and stability of the installation position of the disassembly block 5, avoids the disassembly block 5 from shifting or rotating during use, and ensures the reliability of the tightening operation.

[0026] like Figures 1 to 4As shown, several grooves 6 are arranged in a ring array. The ring array of grooves 6 makes the friction force in all directions more uniform when the bolt contacts the connector, which enhances the anti-slip effect of the bolt and improves the stability of the connection.

[0027] Furthermore, both the bolt head 1 and the screw 2 are made of titanium alloy. Titanium alloy has advantages such as high strength, good corrosion resistance and light weight, which allows the bolt to withstand large loads and be used in harsh environments without easily rusting or corroding. At the same time, it reduces the overall weight and is suitable for occasions where weight is a requirement.

[0028] like Figures 1 to 4 As shown, the outer surfaces of the bolt head 1 and the screw 2 are coated with an anti-corrosion coating, and a sealing washer 4 is provided at the connection between the bolt head 1 and the screw 2. The anti-corrosion coating further enhances the bolt's corrosion resistance, while the sealing washer 4 can prevent external moisture, dust and other impurities from entering the bolt, protecting the connection part of the bolt and extending the bolt's service life.

[0029] It is worth noting that a guide head 3 is fixedly connected to the bottom end of the screw 2. The guide head 3 is hemispherical, and the outer surface of the guide head 3 is treated to reduce the coefficient of friction. The hemispherical guide head 3, together with the treatment to reduce the coefficient of friction, can more easily guide the screw 2 into the mounting hole when installing the bolt, reducing the installation resistance, improving the installation efficiency, and also avoiding collision damage between the end of the screw 2 and the mounting hole.

[0030] Working principle and process: When installing the anti-slip gear groove 100° countersunk titanium alloy bolt, firstly, the hemispherical structure and low friction coefficient of the guide head 3 are used to smoothly insert the screw 2 into the installation hole. Then, the tool is inserted into the tightening groove 51 at the top of the disassembly block 5, and the bolt is tightened by rotating the tool. The annular array tooth groove 6 on the inclined surface of the bolt head 1 is in close contact with the surface of the connecting part, increasing the friction and preventing the bolt from loosening. The cooperation between the positioning block 52 and the positioning groove 55 ensures the stability of the disassembly block 5. The magnetic coating 56 and the adsorption of the iron sheet 54 facilitate the installation and replacement of the disassembly block 5. The titanium alloy material of the bolt head 1 and the screw 2, as well as the anti-corrosion coating and sealing gasket 4 on the outer surface, together ensure the long-term stable use of the bolt in various environments.
