Description

Technical Field

[0001] This utility model relates to the technical field of anti-loosening gaskets, and more particularly to embedded elastic anti-loosening gaskets. Background Technology

[0002] Gaskets are flexible or semi-rigid materials placed between the mating surfaces of mechanical parts. They fill microscopic unevenness on the surface by deforming under pressure, forming an effective sealing barrier.

[0003] During the assembly of aluminum alloy enclosures, traditional anti-loosening methods are ineffective in preventing threaded connections from loosening due to the relatively soft nature of aluminum alloy. This is especially problematic under vibration or impact conditions, where nuts are prone to loosening, affecting structural reliability. Existing technologies often rely on increasing friction or deformation resistance, but the aluminum alloy surface is easily worn, leading to a decrease in anti-loosening effectiveness. Furthermore, conventional anti-rotation washers tend to slip when combined with soft enclosures, failing to provide stable anti-rotation. Therefore, there is an urgent need for an anti-loosening structure specifically designed for the characteristics of aluminum alloy enclosures, one that effectively prevents rotation and enhances anti-loosening performance through mechanical interlocking, ensuring long-term stability of the connections. Utility Model Content

[0004] The purpose of this utility model is to provide an embedded elastic anti-loosening gasket in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: including a gasket body, a nut, and a sleeve for use with the gasket body;

[0006] The gasket body includes a hexagonal gasket, with cut-off heads fixedly provided on two opposite sides of the hexagonal gasket, and a clamping piece fixedly provided at the middle position of the other sides of the hexagonal gasket;

[0007] The cutting head has a cutting surface for cutting aluminum alloy material at the end away from the hexagonal pad, and the cutting head is inclined.

[0008] This patent addresses the issue of assembling components into an aluminum alloy enclosure. Utilizing the relatively soft nature of the aluminum alloy material, an embedded elastic gasket is used. When the gasket body is subjected to the tightening force of the nut, the cut end is embedded into the aluminum alloy enclosure body to achieve an anti-rotation effect. After the nut is tightened to the pre-tightening force, the clamping plate is bent to clamp the nut. In this way, the nut and the aluminum alloy enclosure become "one unit," achieving an anti-loosening effect.

[0009] Furthermore, clamping plates for use with the cutting head are fixedly provided on both sides of the sleeve, and the clamping plates are inclined; the clamping plates press the cutting head to prevent the end of the cutting head from lifting up, and the sleeve can effectively prevent the clamping plates from loosening, which would cause the clamping plates to be unable to hold the nut.

[0010] Furthermore, the connection between the clamping piece and the hexagonal pad is provided with a bending indentation to facilitate bending, allowing the clamping piece to be easily bent through the bending indentation.

[0011] Furthermore, the outer wall of the sleeve is provided with a tearing groove, which makes it easy for workers to disassemble the sleeve and remove it quickly.

[0012] Furthermore, multiple sets of anti-slip cones are fixedly provided on the side of the hexagonal pad that is in contact with the aluminum alloy material to increase the friction between the hexagonal pad and the aluminum alloy material.

[0013] Furthermore, the gasket body is made of elastic 35Mn, and also has a certain degree of flexibility to facilitate bending and deformation.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This embedded elastic anti-loosening washer is designed for use after assembling components in an aluminum alloy enclosure. Utilizing the relatively soft nature of the aluminum alloy material, the embedded elastic washer cuts into the aluminum alloy enclosure body under the pressure of the nut, preventing rotation. After the nut is tightened to the pre-tightening force, the clamping plate is bent to clamp the nut, thus making the nut and the aluminum alloy enclosure "one unit," achieving an anti-loosening effect.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings, but the present invention is not limited thereto.

[0022] Reference Figure 1-4 An embedded elastic anti-loosening washer includes a washer body 1, a nut 2, and a sleeve 3 that works with the washer body 1.

[0023] The gasket body 1 includes a hexagonal gasket 101, with cut-off heads 103 fixedly provided on two opposite sides of the hexagonal gasket 101, and clamping pieces 102 fixedly provided at the middle position of the other sides of the hexagonal gasket 101.

[0024] The end of the cutting head 103 away from the hexagonal pad 101 has a cutting surface for cutting aluminum alloy materials, and the cutting head 103 is set at an angle.

[0025] This patent addresses the issue of assembling components into an aluminum alloy enclosure. Utilizing the relatively soft nature of the aluminum alloy material, an embedded elastic gasket is used. When the gasket body 1 is subjected to the tightening force of the nut, the cutter head 103 is embedded into the aluminum alloy enclosure body to achieve an anti-rotation effect. After the nut 2 is tightened to the pre-tightening force, the clamping plate 102 is bent to clamp the nut 2, thus making the nut 2 and the aluminum alloy enclosure "integrated" and achieving an anti-loosening effect.

[0026] Furthermore, refer to Figure 1-3 The sleeve 3 has a clamping plate 301 fixed on both sides for use with the cutter head 103. The clamping plate 301 is inclined. The clamping plate 301 clamps the cutter head 103 to prevent the end of the cutter head 103 from lifting. At the same time, the sleeve 3 can effectively prevent the clamping plate 102 from loosening, which would cause the clamping plate 102 to be unable to hold the nut 2.

[0027] Furthermore, refer to Figure 3 The clamping piece 102 and the hexagonal pad 101 are connected by a bending indentation 104 to facilitate bending. The clamping piece 102 can be easily bent through the bending indentation 104.

[0028] Furthermore, refer to Figure 1 The outer wall of the sleeve 3 is provided with a tearing groove 302, which makes it easy for workers to disassemble the sleeve 3 and remove it quickly.

[0029] Furthermore, refer to Figure 4 Multiple anti-slip cones 1011 are fixedly provided on the side of the hexagonal pad 101 that is in contact with the aluminum alloy material to increase the friction between the hexagonal pad 101 and the aluminum alloy material.

[0030] Furthermore, the gasket body 1 is made of elastic 35Mn, which also has a certain degree of flexibility to facilitate bending and deformation.

[0031] Working principle:

[0032] This embedded elastic anti-loosening gasket is designed for use after assembling components in an aluminum alloy enclosure. Utilizing the relatively soft nature of the aluminum alloy material, the embedded elastic gasket is designed so that when the gasket body 1 is subjected to the tightening force of the nut, the cut-off head 103 is embedded into the aluminum alloy enclosure body to achieve an anti-rotation effect. After the nut 2 is tightened to the pre-tightening force, the clamping plate 102 is bent to clamp the nut 2, thus making the nut 2 and the aluminum alloy enclosure "integrated" and achieving an anti-loosening effect.
