Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to automobile bolts. Background Art

[0002] A bolt is a mechanical part, a cylindrical, threaded fastener that fits a nut. This type of fastener consists of a head and a shank (a cylindrical body with external threads). It mates with a nut to securely connect two parts with through-holes. This type of connection is called a bolted connection. Removing the nut from the bolt allows the two parts to separate, making bolted connections removable. Bolts are indispensable in daily life and industrial manufacturing, earning them the nickname "the rice of industry." This demonstrates their widespread application. Bolts are used in electronics, mechanical products, digital products, electrical equipment, and electromechanical products. They are also found in ships, vehicles, hydraulic engineering projects, and even chemical experiments. Bolts are used in a wide variety of applications, including precision bolts for digital products, miniature bolts for DVDs, cameras, eyeglasses, clocks, and electronics, and standard bolts for televisions, electrical appliances, musical instruments, and furniture. Large bolts and nuts are used in engineering, construction, and bridges, while a combination of large and small bolts are used in transportation, aircraft, trams, and automobiles. Bolts play an important role in industry. As long as there is industry on earth, the function of bolts will always be important.

[0003] The application number is CN202022291985.1, which discloses an automobile bolt for automobile accessories, including a screw, a nut is provided on the left side of the screw, the screw and the nut are made of the same material, the surface of the screw is provided with threads from left to right, the outer surface of the screw is provided with a reinforcement layer, the outer surface of the reinforcement layer is provided with a rust-proof layer, the outer surface of the rust-proof layer is provided with a high-temperature resistant layer, the outer surface of the high-temperature resistant layer is provided with a wear-resistant layer, and the wear-resistant layer includes a carbon steel layer, an iron alloy layer and a steel alloy layer. In the utility model, the screw, the nut, the thread, the reinforcement layer, the rust-proof layer, the high-temperature resistant layer and the wear-resistant layer cooperate with each other to achieve the advantage of good wear resistance, solve the problem of poor wear resistance of existing automobile bolts, have high use strength, and repeated use of automobile bolts will not cause damage to the automobile bolts, thereby extending the service life of the bolts, and will not cause the automobile bolts to loosen, and there will be no safety hazards.

[0004] Although the above-mentioned utility model achieves the advantage of good wear resistance through the mutual cooperation of the screw, nut, thread, reinforcement layer, rust-proof layer, high-temperature resistant layer and wear-resistant layer, and solves the problem of poor wear resistance of existing automobile bolts, it has high use strength and can use the automobile bolts repeatedly without causing damage to the automobile bolts, thereby extending the service life of the bolts, preventing the automobile bolts from loosening, and posing no safety hazards. However, there is a disadvantage that the device may loosen and fall off during use, which will affect the overall device in the later stage.

[0005] Therefore, it is necessary to install a splicing screw assembly and a lubricating screw assembly on the device, so that when the device is used, its components can provide a lubricating effect. In this way, rust and other problems can be avoided during long-term use, thereby extending the durability of the device. Utility Model Content
