Description

Technical Field

[0001] The utility model relates to the field of elastic washers, in particular to an elastic washers with high strength. Background Art

[0002] Elastic washers, also known as spring washers, are commonly used in equipment installation. Compared with flat washers, spring washers can not only prevent nuts from scratching the installation surface, but also increase the preload force and friction. However, since spring washers are not closed, their ability to withstand radial forces is weak. During transportation or storage, if they are squeezed by radial forces exceeding the elastic limit, they may not be able to recover, resulting in a smaller inner diameter, which in turn causes interference at the fracture position when the spring washers are compressed.

[0003] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a high-strength elastic washer, which is achieved through the following technical solutions:

[0005] A high-strength elastic gasket comprises a gasket body, which is not closed and is spiral-shaped. A plurality of load-bearing blocks are arranged on the inner wall of the gasket body, and the plurality of load-bearing blocks are evenly arranged. A surplus gap is arranged between two adjacent load-bearing blocks, and the width of the surplus gap is related to the elastic limit of the gasket body. The load-bearing blocks are not perpendicular to the inner wall surface of the gasket body.

[0006] In the above technical solution: the gasket body is used to realize the basic function of the gasket; the load-bearing block is used to withstand the radial extrusion force; the residual gap is used to enable the gasket body to elastically deform within the elastic limit to avoid the inner wall surface from being deformed by extrusion.

[0007] The utility model is further configured as follows: the inner wall surface of the load-bearing block is in an arc shape, and the centers of the arc surfaces of the inner wall surfaces of all the load-bearing blocks coincide.

[0008] In the above technical solution: the inner wall surface of the load-bearing block is arc-shaped, and the centers of the arc surfaces coincide, so that the bolt is not easily stuck by the load-bearing block when passing through the washer body.

[0009] The utility model is further configured as follows: a vertical distance between the highest point of the top surface of the load-bearing block and the lowest point of the bottom surface of the load-bearing block is not greater than the thickness of the gasket body.

[0010] In the above technical solution: the vertical distance between the highest point of the top surface of the load-bearing block and the lowest point of the bottom surface of the load-bearing block is not greater than the thickness of the gasket body, so that after the gasket body is compressed, the load-bearing block will not contact the connecting surface of the connecting piece to avoid scratches.

[0011] The utility model is further configured as follows: rounded corners are arranged on both sides of the inner wall surface of the load-bearing block close to the residual gap.

[0012] In the above technical solution: the rounded corners are set to prevent the corners of the load-bearing blocks from breaking after contact and extrusion.

[0013] The utility model is further configured as follows: the thickness of the load-bearing block is half of the thickness of the gasket body.

[0014] In the above technical solution: the thickness of the load-bearing block is half the thickness of the gasket body, which is used to avoid the strength of the load-bearing block being too low.

[0015] The utility model discloses a high-strength elastic gasket. Compared with the prior art:

[0016] 1. The utility model provides a load-bearing block to enhance the ability of the elastic gasket to withstand radial force, thereby avoiding damage to the elastic gasket due to the deformation of the gasket body exceeding the elastic limit of the gasket body after being subjected to radial force;

[0017] 2. The utility model also allows the gasket body to undergo elastic deformation within a certain range within the elastic limit through the residual gap, thereby avoiding direct damage to part of its structure when subjected to radial force. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following is a detailed description of an embodiment of the utility model. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0022] like Figure 1 , 2As shown, the utility model proposes a high-strength elastic gasket, including a gasket body 10, the gasket body 10 is not closed, and the gasket body 10 is spiral, a plurality of bearing blocks 20 are arranged on the inner wall of the gasket body 10, and the plurality of bearing blocks 20 are evenly arranged, and a residual gap 30 is arranged between two adjacent bearing blocks 20, the width of the residual gap 30 is related to the elastic limit of the gasket body 10, and the bearing block 20 is not perpendicular to the inner wall surface of the gasket body 10. Among them, the bearing block 20 is spirally moved in the length direction.

[0023] like Figure 1 , 2 As shown, the utility model proposes a high-strength elastic gasket, the inner wall surface of the load-bearing block 20 is arc-shaped, and the centers of the arc surfaces of the inner wall surfaces of all the load-bearing blocks 20 coincide. Among them, the corresponding radius of the arc surface of the inner wall surface is related to the diameter of the corresponding bolt.

[0024] like Figure 1 , 2 As shown, the utility model proposes a high-strength elastic gasket, in which the vertical distance between the highest point of the top surface of the load-bearing block 20 and the lowest point of the bottom surface of the load-bearing block 20 is not greater than the thickness of the gasket body 10.

[0025] like Figure 1 , 2 As shown, the utility model proposes a high-strength elastic gasket, and the inner wall surface of the bearing block 20 is provided with rounded corners on both sides close to the residual gap 30. Preferably, the bottom edge of the inner wall surface of the bearing block 20 is also provided with rounded corners to prevent the bottom plate from scratching the thread of the bolt.

[0026] like Figure 1 , 2 As shown, the utility model proposes a high-strength elastic gasket, in which the thickness of the load-bearing block 20 is half of the gasket body 10 .

[0027] The working principle of the utility model is:

[0028] a) When the gasket body is squeezed by radial force;

[0029] b) The gasket body has a tendency to shrink;

[0030] c) The remaining gap is reduced until all adjacent bearing blocks are in contact with each other;

[0031] d) If it continues to be squeezed by radial force;

[0032] e) The bearing blocks bear pressure by abutting against each other;

[0033] f) When the radial force disappears, the gasket body can restore its original shape because its deformation does not exceed the elastic limit; g) This avoids the interference between the two ends of the elastic gasket caused by the reduction of the inner diameter of the gasket body.

[0034] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
