Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a rust-proof threaded sliding sleeve for automobiles. Background Art

[0002] The car's generator is fixed to the engine by bolts passing through the fixing bracket and the generator hanging angle; however, a threaded sleeve is required in the mounting hole of the generator hanging angle to ensure that the generator hanging angle and the mounting surface of the bracket fit tightly after tightening the fixing bolts, thereby preventing fatigue fracture of the generator and the bracket due to relative movement.

[0003] The connection of many parts of a car requires the use of threaded sleeves, and most of the threaded sleeves are inside the car. Due to changes in temperature and humidity inside the car, the threaded sleeves are prone to rust over time. Rust will cause the threaded sleeves to stick and become difficult to unscrew. Therefore, the utility model proposes a new solution. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a rust-proof threaded sleeve for automobiles, which can solve the problem that the connection of many parts of an automobile depends on threaded sleeves, and most threaded sleeves are inside the automobile. Due to changes in temperature and humidity inside the automobile, the threaded sleeves are prone to rust over time, and rust can cause the threaded sleeves to stick together and be difficult to unscrew.

[0005] To achieve the above object, the utility model provides the following technical solution: an anti-rust threaded sleeve for automobiles, comprising a threaded sleeve body, a guide block fixedly connected to the upper end of the threaded sleeve body, an inner wall of the threaded sleeve body having an internal thread, and an outer wall of the threaded sleeve body having an external thread;

[0006] The inner wall of the guide block is provided with a first groove, the inner wall of the threaded sleeve body is provided with a second groove, and the surface of the threaded sleeve body is provided with a first through groove and a second through groove;

[0007] The surfaces of the guide block and the threaded sleeve body are provided with a molybdenum disulfide coating, and the inner and outer surfaces of the guide block and the threaded sleeve body are subjected to heat treatments such as quenching and normalizing.

[0008] Preferably, the inner wall of the first groove is slidably connected to a first limiting ring, the inner wall of the first through groove is slidably connected to a first limiting strip, the inner wall of the second groove is slidably connected to a second limiting ring, and the inner wall of the second through groove is slidably connected to a second limiting strip.

[0009] Preferably, the first limiting ring and the first limiting strip are fixedly connected, and the second limiting ring and the second limiting strip are fixedly connected.

[0010] Preferably, the inner walls of the first limiting ring and the first limiting strip are provided with a first thread, and the inner walls of the second limiting ring and the second limiting strip are provided with a second thread.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. This rust-proof threaded sleeve for automobiles uses a guide block, which makes it easy to install and remove the guide block and the threaded sleeve body using tools such as wrenches. Heat treatment of the guide block and the threaded sleeve body can enhance the hardness and strength of the guide block and the threaded sleeve body, making them more resistant to external forces and wear during use. A molybdenum disulfide coating is provided on the surface of the guide block and the threaded sleeve body, and the molybdenum disulfide is cured by a high-temperature curing process or a room-temperature curing process. Molybdenum disulfide has good corrosion resistance and rust protection capabilities, and can effectively protect metal parts from external erosion. The rust-proof treatment can significantly enhance the rust resistance of the guide block and the threaded sleeve body, preventing them from rusting in harsh environments such as moisture and corrosion, thereby extending their service life and avoiding the loss of expensive substrate replacement due to the inability to disassemble the threaded hole due to rust.

[0013] 2. The rust-proof threaded sleeve for automobiles is convenient for installing the guide block and the threaded sleeve body by means of the arrangement of the first through groove and the second through groove, so that they can be installed according to the size of the mounting hole with slight deformation during the installation process. The first through groove and the second through groove are symmetrically arranged on the surface of the threaded sleeve body up and down, which can prevent the guide block and the threaded sleeve body from being deformed too much and causing the guide block and the threaded sleeve body to tear, and ensure that the sleeve can fit tightly with the mounting surface of the bracket when the bolt is tightened, so as to ensure the stability of the guide block and the threaded sleeve body during installation. The design of the first through groove and the second through groove makes it possible to use specific tools or fingers to directly act on the through grooves during installation or disassembly, thereby making it easier to tighten or loosen the guide block and the threaded sleeve body, thereby improving the convenience of operation and improving the connection strength between the threaded sleeve and the connecting component.
