Description

Technical Field

[0001] This utility model relates to the field of bolt technology, specifically high-strength and durable automotive bolts. Background Technology

[0002] Bolts are tools that use the physical and mathematical principles of inclined planes, circular rotation, and friction to gradually fasten objects and machine parts. In the automotive industry, bolts are often exposed to the outside and frequently come into contact with water, which can lead to rust and make them difficult to remove, hindering subsequent disassembly and maintenance work.

[0003] A search revealed that patent application CN118757496A discloses a high-strength and durable automotive bolt structure, including a bolt nut. The top of the bolt nut has an oil filling connection hole, and a top connecting bolt is located at the center of the top of the oil filling connection hole. A nut cap is connected to the top connecting bolt. A waterproof washer is located below the bolt nut, and an anti-loosening ring is connected to the outer side of the waterproof washer. An oil filling and tightening connecting block is connected below the waterproof washer, and a fixing bolt is connected to the bottom of the oil filling and tightening connecting block. This allows for oil lubrication and prevents rust from forming on the automotive threads.

[0004] However, due to the setting of the fixing bolt and fastening block, after the nut is installed, rainwater from the outside can easily flow onto the contact point between the nut and the fixing bolt, resulting in low waterproof performance and easy rusting and stripping. This leads to poor performance. At the same time, when the fixing bolt strips or rusts, the nut cannot be disassembled, making it inconvenient to remove the bolt and hindering later maintenance.

[0005] Therefore, we propose high-strength, durable automotive bolts. Utility Model Content

[0006] In response to the shortcomings of existing technologies, this utility model provides a high-strength and durable automotive bolt, which solves the problems of low waterproof performance and inconvenient bolt disassembly in existing devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-strength and durable automotive bolt, including a nut, wherein the bottom surface of the nut is fitted with a threaded rod of a matching specification;

[0008] The outer wall of the screw is fitted with a nut of a matching specification. The top surface of the nut is fitted with a fastening washer A of a matching specification. The top surface of the fastening washer A is fitted with a waterproof washer A. The bottom surface of the nut is fitted with a fastening washer B of a matching specification. The bottom surface of the fastening washer B is fitted with a waterproof washer B. The fastening washers A and B are made of metal, and the waterproof washers A and B are made of rubber.

[0009] The top surface of the nut has a through groove, and the top end of the screw is fixedly installed with a fixing rod that is slidably connected to the through groove. The top end of the fixing rod is fixedly installed with a connecting block of the same specification. The top surface of the connecting block has a cross groove, and the inner wall of the nut is fixedly installed with a cross block of the same specification. The cross block and the cross groove are connected by welding.

[0010] Preferably, the bottom surface of the fastening washer B has a groove that matches the specifications of the waterproof washer B, and the waterproof washer B protrudes from the bottom surface of the fastening washer B, which can improve the connection and sealing between the fastening washer B and the waterproof washer B.

[0011] Preferably, the diameter of the connecting block is smaller than the diameter of the through slot, which makes it easier to cut the cross-shaped retaining block shorter, thereby facilitating the disassembly of the screw.

[0012] Preferably, a threaded groove is formed on the inner wall of the top of the through groove, a sealing cap of the same specification is fitted on the top surface of the nut, and a sealing screw of the same specification is fixedly installed on the bottom surface of the sealing cap. This can seal the top surface of the through groove, prevent rainwater from entering the through groove, and improve its service life.

[0013] Preferably, the bottom surface of the sealing cap is fitted with a rubber pad layer of matching specifications, which can improve the sealing performance of the sealing cap.

[0014] Preferably, the horizontal cross-section of the nut and the sealing cap is hexagonal, which facilitates installation and removal using a hex wrench.

[0015] 1. This high-strength and durable automotive bolt, through the setting of fastening washer A and waterproof washer B, after the nut is installed, the fastening washer A and fastening washer B can improve the firmness and stability of the nut and bolt installation, and the waterproof washer A and waterproof washer B can waterproof the top surface of the nut and the bottom surface of the nut, preventing rainwater from entering the inner wall of the nut and causing rust, thus improving waterproof performance and service effectiveness.

[0016] 2. Simultaneously, through the setting of the fixing rod, cross slot and cross block, the screw and fixing rod are inserted into the through groove, the cross slot and cross block are combined, and then the cross slot and cross block are fixedly connected by welding. When the nut cannot be removed due to rust, the screw and bolt can be removed by cutting the cross block, thereby improving the convenience of disassembly. Attached Figure Description
