[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-3 , the utility model provides an embodiment: an improved triangular nut for automobiles, including a fixing plate 1, a fixing ring 2 is fixedly connected to the lower surface of the fixing plate 1, a fixing ring 2 is arranged at the bottom of the fixing ring 2, a fixing column 4 is arranged between the fixing ring 2 and the fixing ring 3, a ring groove 5 is provided inside the fixing ring 23, the fixing column 4 is fixedly connected inside the ring groove 5, a spring 6 is sleeved on the outer wall of the fixing column 4, one end of the spring 6 is fixedly connected inside the ring groove 5, and the other end of the spring 6 is fixedly connected to the lower surface of the fixing ring 2, a connecting hole 7 is provided inside the fixing ring 2, the outer wall of the fixing column 4 is slidably connected inside the connecting hole 7, a wiring assembly is provided on the upper surface of the fixing plate 1, and a threaded groove 10 is provided inside the fixing plate 1;

[0026] Specifically, when we connect the bolts with the equipment only at the position corresponding to the automobile parts, the fixing ring 2 3 begins to play its role. It is acted upon by force, so that the spring 6 is squeezed. The squeezing force pushes the fixing column 4 to slide into the connecting hole 7, thereby achieving engagement. At this time, the squeezed spring 6 and the remaining fixing column 4 not inserted into the connecting hole 7 will remain in the position of the ring groove 5. This design cleverly enables the fixing ring 2 3 and the fixing ring 1 2 to fit completely together, and the restorability of the spring 6 will produce a reaction force, continuing to squeeze the fixing ring 2 3. This makes it possible for the fixing plate 1 to be connected with the bolt, in addition to the force generated by the thread corresponding to the thread groove 10, tension will also be generated inside it. This tension applies a continuous axial force to the bolt, thereby effectively preventing the bolt from loosening, thereby ensuring the firmness of the bolt and enhancing the durability and safety of the equipment.

[0027] Reference Figure 1-2 and 4, the wiring assembly includes a threading plate 8 and a threading hole 9, the threading plate 8 is fixedly connected to the upper surface of the fixed plate 1, the threading hole 9 is opened inside the threading plate 8, a groove 11 is opened inside the fixed plate 1, a film ball 12 is arranged at the bottom of the threading hole 9, the film ball 12 is arranged inside the groove 11, and an adhesive is arranged inside the film ball 12;

[0028] Specifically, when the bolt is rotated and connected at the position of the thread groove 10, a corresponding portion of the film ball 12 is left in the groove 11, while the other portion is left outside and is not wrapped by the groove 11. These film balls 12 left outside are easily scratched during the rotation of the bolt. Once the film ball 12 is scratched, the adhesive inside will leak out. The adhesive plays a vital role in this process. It not only fills the gap between the bolt and the thread groove 10, but also increases the torque required to remove the bolt. This means that the fixing strength between the bolt and the fixing plate 1 is significantly improved. In order to meet different needs, there are a variety of options for the adhesive in the film ball 12, including removable type: Loctite 242, medium strength: Loctite 243 and permanent fixing type: Loctite 263. These different types of adhesives have their own characteristics and application scenarios. For example, removable adhesives are suitable for occasions that require disassembly, while permanent fixing types are suitable for occasions that require long-term fixation. Choosing a suitable adhesive model is crucial to ensuring a stable connection between the bolt and the fixing plate 1.

[0029] Working principle: When the equipment is used to fix the bolt position, the corresponding bolt is rotated between the fixing plates 1 and connected with the thread groove 10. When the bolt is connected to the corresponding required fixing part in cooperation with the equipment, the corresponding fixing ring 2 3 will be acted upon by force, so that the spring 6 is squeezed, so that the corresponding fixing column 4 will slide into the connecting hole 7 to achieve engagement, and the squeezed spring 6 and the remaining fixing column 4 not inserted into the connecting hole 7 will remain in the position of the ring groove 5, so that the fixing ring 2 3 and the fixing ring 1 2 can be completely fitted together. At this time, the corresponding spring 6 will squeeze the fixing ring 2 3 through the reaction force generated by its own reduction, so that when the fixing plate 1 is connected with the bolt, except for the corresponding thread groove 10 Some thread forces will also generate tension inside, thereby applying continuous axial force to the bolt to prevent the bolt from loosening, and when the corresponding bolt is rotated and connected at the position of the thread groove 10, part of the corresponding film ball 12 remains in the groove 11, and part of it is left outside and not wrapped by the groove 11. The corresponding film ball 12 remaining outside will be scratched by the rotation of the bolt, and the adhesive filled inside it will leak out, thereby tightening the gap between the bolt and the thread groove 10, thereby increasing the torque required for unscrewing, thereby making the fixing strength between the bolt and the fixing plate 1 higher, and the adhesive in the corresponding film ball 12 can be selected according to whether the required installation position needs to be disassembled later, such as detachable type: Loctite 242, medium strength: Loctite 243 and permanent fixed type: Loctite 263. The wires of the corresponding automotive parts can pass through the threading holes 9 in the threading plate 8 to achieve line binding.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
