[0020] Please refer to Figures 1-4 As shown in FIG. 1, a stainless steel conical washer for sheet metal assembly, comprising a conical washer body 1, a anti-loose structure 2 is installed on the conical washer body 1, the anti-loose structure 2 comprises a mounting groove 201, the mounting groove 201 is arranged on the conical washer body 1, a spring washer 202 is installed in the mounting groove 201, a pressure ring 203 is slidably connected to the conical washer body 1, one end of the spring washer 202 abuts against the conical washer body 1, the other end of the spring washer 202 abuts against the pressure ring 203, a bolt 3 penetrates through the middle of the conical washer body 1, and the bolt 3 abuts against the pressure ring 203.

[0021] As a technical optimization scheme of the present application, the cross section of the pressure ring 203 is in a "T" shape structure, the head of the bolt 3 is in a trapezoidal structure, the inner wall of the pressure ring 203 is provided with a first inclined surface 204, and the head of the bolt 3 abuts against the first inclined surface 204; the rectangular end face of the conical washer body 1 is downward, and is aligned with the mounting hole of the sheet metal part, then the bolt 3 is sequentially penetrated through the mounting hole of the sheet metal part, the center through hole of the conical washer body 1 and the pressure ring 203, the bolt 3 is moved into the mounting hole of the sheet metal part by turning the bolt 3 with a wrench, because the cross section of the head of the bolt 3 is in a trapezoidal structure, the bolt 3 moves downward by abutting against the first inclined surface 204 to move the pressure ring 203 downward, so as to drive the pressure ring 203 to compress the spring washer 202, and then the spring washer 202 is elastically deformed to store pre-tightening force and compensate possible loosening of the bolt 3 in the future, the spring washer 202 and the conical washer body 1 form a double anti-loose effect, and the anti-vibration ability of the bolt 3 connection is significantly improved.

[0022] As a technical optimization scheme of the present application, the outer wall of the conical washer body 1 is provided with a second inclined surface 4, and the cross section of one end of the conical washer body 1 away from the pressure ring 203 is in a rectangular structure; the second inclined surface 4 on the conical washer body 1 can reduce the problem of stress concentration of the washer, thereby reducing the damage to the sheet metal part.

[0023] As a technical optimization of this utility model, the conical washer body 1 is provided with a groove 5, a rubber ring 6 is engaged in the groove 5, and a rubber pad 9 is installed on the conical washer body 1. The cross-section of the rubber pad 9 is rectangular. The rubber ring 6 can concentrate the pressure of the tip of the conical washer body 1, and the rubber pad 9 can disperse the edge stress. Through the cooperation of the rubber ring 6 and the rubber pad 9, a composite functional layer of central rigid support and edge elastic sealing is formed under the pre-tightening force of the bolt 3.

[0024] As a technical optimization of this utility model, the outer thread of the conical washer body 1 is connected to a protective cover 7, and the outer wall of the protective cover 7 is provided with multiple slots 8; the protective cover 7 is sleeved on the outside of the conical washer body 1, so that the protective cover 7 is threadedly connected to the threaded section of the conical washer body 1. The slots 8 on the protective cover 7 can increase the friction between the protective cover 7 and the wrench, ensuring that after the protective cover 7 is tightened, it covers the head of the bolt 3 and the pressure ring 203, forming a dustproof and waterproof barrier.

[0025] In use, the rectangular end face of the conical washer body 1 is first aligned with the mounting hole of the sheet metal part, facing downwards. Then, the bolt 3 is passed sequentially through the mounting hole of the sheet metal part, the central through hole of the conical washer body 1, and the pressure ring 203. The bolt 3 is then tightened with a wrench, causing it to move into the mounting hole of the sheet metal part. Due to the trapezoidal cross-section of the bolt 3 head, the bolt 3 moves downwards by engaging with the first inclined surface 204, which in turn causes the pressure ring 203 to compress the spring washer 202. This causes the spring washer 202 to undergo elastic deformation and store preload, compensating for any subsequent loosening of the bolt 3. The spring washer 202 and the conical washer body 1 create a dual anti-loosening effect, significantly improving the vibration resistance of the bolt 3 connection. Continuing to tighten the bolt 3 causes it to drive the lower end face of the conical washer body 1... The tapered washer body 1 is tightened against the sheet metal parts, thereby enhancing the stability of the sheet metal assembly. The second inclined surface 4 on the tapered washer body 1 can reduce the stress concentration of the washer, thereby reducing damage to the sheet metal parts. The rubber ring 6 can concentrate the pressure of the tip of the tapered washer body 1, and the rubber pad 9 can disperse the edge stress. Through the cooperation of the rubber ring 6 and the rubber pad 9, a composite functional layer of central rigid support and edge elastic sealing is formed under the pre-tightening force of the bolt 3. After the tapered washer body 1 and the bolt 3 are fixed on the sheet metal parts, the protective cover 7 is then put on the outside of the tapered washer body 1, so that the protective cover 7 is threadedly connected to the threaded section of the tapered washer body 1. The groove 8 on the protective cover 7 can increase the friction between the protective cover 7 and the wrench, ensuring that the protective cover 7 covers the head of the bolt 3 and the pressure ring 203 after being tightened, forming a dustproof and waterproof barrier.

[0026] The above merely is the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited to this, any skilled person in the technical field according to the technical scheme and the utility model concept of the present utility model within the technical range disclosed by the present utility model makes equivalent replacement or change, should be covered in the protection scope of the present utility model.
