[0002] Automotive parts are the various units that make up a car and the products that serve the car. There are many types of automotive parts. With the improvement of people's living standards, people's consumption of cars is also increasing, and the market for automotive parts is becoming larger and larger. In recent years, automotive parts manufacturers have also developed rapidly. Welding nuts are commonly used in automotive parts for fixing operations. Welding nuts are nuts that are suitable for welding. They are generally made of weldable materials and are relatively thick to be suitable for welding. Welding is equivalent to turning two separate parts into a whole. The metals are melted at high temperature, mixed together, and then cooled. Alloys are added in the middle. The internal molecular forces are the driving force, and the strength is generally greater than that of the base material. The welding parameters are tested according to the fusion size of the weld. The welding parameters are adjusted according to the fusion size until defects are eliminated. Of course, the quality of welding is related to the pre-welding treatment, such as cleaning dust and oil stains. In order to ensure the firmness of the welding nut during use, a four-corner welding nut with anti-slip grooves is particularly needed.

[0003] However, existing four-corner welded nuts often have insufficient welding strength, which can easily lead to the nuts loosening or falling off during use, affecting the performance and even posing a safety hazard to the stability of automotive parts. Utility Model Content

[0016] 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.

[0017] Please see Figure 1-4This utility model provides a technical solution: a four-corner welded nut with an anti-slip groove, comprising a nut body 1, a washer 2 fixedly connected to the inner surface of the nut body 1, a fixing ring 3 fixedly connected to the upper surface of the nut body 1, a fixing pin 4 engaged with the inner surface of the fixing ring 3, a support block 5 rotatably connected to the inner surface of the nut body 1, a fixing block 6 fixedly connected to the inner surface of the nut body 1, a rotating shaft 7 rotatably connected to one side surface of the fixing block 6, and a first spring 8 fixedly connected to one side surface of the support block 5. A limiting block 9 is fixedly fitted onto the inner surface of spring 8. A first push block 10 is fixedly connected to one side surface of the limiting block 9. A second spring 11 is fixedly connected to one end surface of the first push block 10. A second push block 12 is fixedly connected to one end surface of the second spring 11. A locking block 13 is fixedly connected to the outer surface of the second push block 12. A locking bolt 14 is fixedly connected to one end surface of the second push block 12. The system is connected via a nut body 1, washer 2, fixing ring 3, fixing pin 4, support block 5, fixing block 6, rotating shaft 7, first spring 8, limiting block 9, and first push block 1. The arrangement of the second spring 11, second push block 12, locking block 13, and locking bolt 14 is as follows: During use, when the welded part is fixed, the welded part is in contact with the nut body 1. First, the locking bolt 14 is pressed, which squeezes the second push block 12. The second push block 12 compresses the second spring 11. The second spring 11 rebounds, and the compressive force pushes the first push block 10, causing the first spring 8 to compress and push the fixing block 6. The fixing block 6 clamps the welded part, increasing the stability between the welded part and the nut body 1 and preventing problems during the welding process. The device allows for movement of the welded parts, increasing welding efficiency and reducing production costs. Furthermore, the use of shims 2 prevents the nut body 1 from directly contacting the welded parts, extending its service life. The fixing ring 3 and fixing pin 4 limit and fix the nut body 1, preventing it from falling off. The support block 5, fixing block 6, and rotating shaft 7 allow the support block 5 to drive the first push block 10 to rotate, enabling the device to engage and fix welded parts of different sizes, thus improving its practicality.

[0018] Furthermore, two sets of gaskets 2 are provided. The inner surface of the gasket 2 is fixedly connected to the outer surface of the nut body 1. Through the provision of gaskets 2, the gaskets 2 are interlocked and connected during use, and fixed in the welded part and the nut body 1, thereby increasing the stability of the nut body 1.

[0019] Furthermore, the inner wall size of the retaining ring 3 matches the outer wall size of the retaining pin 4. The retaining ring 3 and the retaining pin 4 are engaged and connected. By setting the retaining ring 3, it is ensured that when fixing the nut body 1, the retaining pin 4 can be firmly inserted into the retaining ring 3 to form a stable fixing structure, which avoids the nut body 1 from moving or falling off during the welding process, and improves the stability and reliability of the welding.

[0020] Furthermore, the outer surface of the support block 5 is rotatably connected to the inner surface of the nut body 1, and the inner surface of the support block 5 is rotatably connected to the outer surface of the rotating shaft 7. By setting the support block 5, it is possible to make adaptive adjustments according to welded parts of different sizes and shapes, thereby ensuring the best locking and fixing effect.

[0021] Furthermore, one end surface of the second spring 11 is fixedly connected to one end surface of the first push block 10, and the other end surface of the second spring 11 is fixedly connected to one end surface of the second push block 12. By setting the second spring 11, when the latch 14 is pressed, the compression and rebound of the second spring 11 can realize the quick locking and release between the latch block 13 and the latch 14, ensuring the convenience and reliability of operation.

[0022] Working principle: First, during use, place the welded part above the nut body 1 so that the welded part contacts the washer 2. Then, by pressing the bolt 14, the bolt 14 moves the second push block 12, thereby compressing the second spring 11. As the second push block 12 moves, the locking block 13 also moves. At this time, the first spring 8, under the action of compression force, pushes the fixing block 6 outward, causing the fixing block 6 to rotate on the support block 5 via the pivot 7, thereby clamping the welded part. After the welded part is firmly clamped, release the bolt 14, and the second spring 11 will rebound, pushing the locking block 13 and the bolt 14. Returning to its original position and locking, this device design not only ensures the stability between the welded part and the nut body 1, preventing the welded part from moving during the welding process, thereby improving welding efficiency and reducing production costs, but also prevents the nut body 1 from directly contacting the welded part by setting the gasket 2, extending the service life of the nut body 1. The cooperation of the fixing ring 3 and the fixing pin 4 provides a stable support for the nut body 1, preventing it from falling off during the welding process. In addition, the rotation design of the support block 5, the fixing block 6 and the rotating shaft 7 allows the device to adapt to welded parts of different sizes, improving its practicality.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
