Description

Technical Field

[0001] The utility model relates to the technical field of high-rotation spring washers, in particular to a high-rotation spring washer. Background Art

[0002] Spring washers are widely used in the load-bearing and non-load-bearing structures of general mechanical products. They are characterized by low cost and easy installation, and are suitable for areas that are frequently assembled and disassembled.

[0003] For example, a high-rotation spring washer with the authorization announcement number "CN214533979U" is provided with a rubber pad. When the bottom surface of the nut presses the top surface of the washer, the bottom surface of the washer presses the rubber pad. The soft rubber pad can prevent the surface of the workpiece from being scratched by the bottom surface of the washer, and can protect the surface of the workpiece. By providing a protrusion, when the bottom surface of the nut presses the top surface of the washer, the inner wall of the washer squeezes the protrusion, and the through hole is close to the screw, thereby increasing the friction between the rubber pad and the screw, preventing the screw from radially slipping, and further reinforcing the screw. However, When high-rotation spring washers are in use, the protective gasket and the high-rotation spring washers are a separate structure. When the high-rotation spring washers are pressed downward, the high-rotation spring washers will move on the protective gasket because the ends of the high-rotation spring washers are separated, and the ends of the high-rotation spring washers will be inserted into the protective gasket. In addition, the spring washers are made of steel and are light and high in weight, so the ends of the spring washers are easy to penetrate the protective gasket. Although the pad protection is achieved, local scratches are prone to occur, which reduces the protective performance of the high-rotation spring washers and leads to limitations in the use of high-rotation spring washers. Utility Model Content

[0004] The utility model aims to solve the problem that the protective performance of the high-rotation spring washer is reduced, resulting in the use limitation of the high-rotation spring washer, and proposes a high-rotation spring washer.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high-rotation spring washer is designed, including a spring washer and a second grinding pattern, the front side of the spring washer is processed with the second grinding pattern, the outer wall of the spring washer is connected with a pad protection structure, the left and right sides of the front side of the spring washer are respectively processed with through openings, the inner wall of the through opening is plugged with a straight rod, and the front of the outer wall of the straight rod is located outside the through opening.

[0007] Preferably, the pad protection structure includes an arc plate and a first grinding pattern, the inner wall of the arc plate is fixedly connected to the outer wall of the spring washer, the outer wall of the arc plate is processed with the first grinding pattern, and a bottom plate is fixedly connected to the rear of the inner wall of the arc plate.

[0008] Preferably, the front surface of the base plate is fixedly connected to the rear end surface of the spring washer.

[0009] Preferably, an inner ring is fixedly connected to the inner wall of the spring washer.

[0010] Preferably, the front surfaces of the inner ring, the spring washer and the arc plate are flush with each other.

[0011] Preferably, the rear end face of the inner ring is fixedly connected to the inner side of the front face of the base plate.

[0012] The utility model proposes a high-rotation spring washer, which has the beneficial effect of: applying glue to the inner sides of the arc plate and the bottom plate in the pad protection structure, and then inserting the spring washer into the arc plate, while the rear of the spring washer is fitted with the front of the bottom plate, and the arc plate, the bottom plate and the spring washer are fixed with the glue to form an integrated structure, and then the bottom plate is fitted with the workpiece. When the top of the spring washer is pressed, the pad can form an isolation support between the workpiece and the spring washer to avoid scratches, thereby ensuring the protective performance of the high-rotation spring washer and eliminating the use limitations of the high-rotation spring washer.

[0018] The utility model is further described below in conjunction with the accompanying drawings: Example 1

[0019] See also Figure 1-4 : In this embodiment, a high-rotation spring washer includes a spring washer 1 and a second grinding pattern 4. The spring washer 1 is made of steel, and the front side of the spring washer 1 is processed with the second grinding pattern 4. The second grinding pattern 4 can prevent the top pressed workpiece from slipping. The outer wall of the spring washer 1 is connected with a pad protection structure 2. The left and right sides of the front side of the spring washer 1 are respectively processed with a through opening 6. The inner wall of the through opening 6 is inserted with a straight rod 7, and the front of the outer wall of the straight rod 7 is located outside the through opening 6.

[0020] The pad protection structure 2 includes an arc plate 201 and a first wear pattern 202. The inner wall of the arc plate 201 is fixedly connected to the outer wall of the spring washer 1. The arc plate 201 is made of rubber. The outer wall of the arc plate 201 is processed with the first wear pattern 202. The first wear pattern 202 can increase the friction of the outer wall to avoid slipping. The inner wall of the arc plate 201 is fixedly connected to the rear of the bottom plate 203. The bottom plate 203 is a rubber plate. The front of the bottom plate 203 is fixedly connected to the rear end surface of the spring washer 1.

[0021] Glue is applied to the inner sides of the arc plate 201 and the bottom plate 203 in the protective structure 2, and then the spring washer 1 is inserted into the arc plate 201. At the same time, the rear side of the spring washer 1 is fitted with the front side of the bottom plate 203. The arc plate 201, the bottom plate 203 and the spring washer 1 are fixed with glue to form an integrated structure. Then the bottom plate 203 is fitted with the workpiece. When the top of the spring washer 1 is pressed, the pad 203 can form an isolation support between the workpiece and the spring washer 1 to avoid scratches, thereby ensuring the protective performance of the high-rotation spring washer and eliminating the limitations of the use of the high-rotation spring washer.

[0022] The inner wall of the spring washer 1 is fixedly connected with an inner ring 5 , which is made of steel. The inner ring 5 , the spring washer 1 and the front faces of the arc plate 201 are flush with each other, and the rear end face of the inner ring 5 is fixedly connected to the inner side of the front face of the bottom plate 203 .

[0023] Working principle:

[0024] At the disconnection point of the spring washer 1, one end is higher than the other end, forming a spiral platform as a whole, and the distance between the two ends is far enough to form a high spiral, thereby forming a high spiral spring washer.

[0025] High-twist spring washer installation:

[0026] First, apply glue to the inner sides of the arc plate 201 and the bottom plate 203, then insert the spring washer 1 into the arc plate 201, and at the same time, fit the rear side of the spring washer 1 with the front side of the bottom plate 203, and fix the arc plate 201, the bottom plate 203 and the spring washer 1 with the help of glue to form an integrated structure, and then fit the bottom plate 203 with the workpiece. When the top of the spring washer 1 is pressed, the pad 203 can form an isolation support between the workpiece and the spring washer 1 to avoid scratches.

[0027] High-twist spring washer thickening installation:

[0028] First, the straight rod 7 is plugged into the through-hole 6 on the front side of the spring washer 1 on which the cushion protection structure 2 is installed. When the straight rod 7 is completely inserted, the rear end face of the straight rod 7 will fit with the bottom plate 203. At this time, the front of the outer wall of the straight rod 7 will leak out from the front side of the through-hole 6. Then, the through-hole 6 on the outer wall of the second spring washer 1 on which the cushion protection structure 2 is installed is plugged into the front of the outer wall of the straight rod 7 to complete the thickening of the spring washer 1.
