Description

Technical Field

[0001] The present application relates to the field of gaskets, and in particular to a rotation-stopping gasket structure. Background Art

[0002] Washers are used between bolts and nuts, and can also be used on screws and some connectors with threaded holes.

[0003] One type of gasket is an elastic gasket, which increases the force on the bolt's nut away from the nut or the connector by pressing the nut of the bolt on the gasket to cause the gasket to elastically deform, thereby increasing the preload force of the threaded connection.

[0004] However, in some usage scenarios, the position where the bolt is located will vibrate, which will cause relative rotation between the bolt and the gasket or the bolt and the nut and the connector. Long-term use will affect the stability of the threaded connection and cause the connection to loosen. Utility Model Content

[0035] Example 1

[0036] A rotation-stopping washer structure comprises a washer body 1 and an object to be connected 2. The washer body 1 is an annular plate. The object to be connected 2 is formed with threads that mate with a bolt. The washer body 1 is disposed between the object to be connected 2 and the nut portion of the bolt. The washer body 1 is made of aluminum alloy.

[0037] The gasket body 1 includes a first abutting surface 11 and a second abutting surface 12. The first abutting surface 11 is one end surface of the gasket body 1, and the second abutting surface 12 is the other end surface of the gasket body 1. The first abutting surface 11 and the second abutting surface 12 are arranged opposite each other; a limit portion 3 or an anti-slip portion is provided on the first abutting surface 11; and a limit portion 3 or an anti-slip portion is provided on the second abutting surface 12. The limit portion 3 is used to be inserted or embedded into the object 2 to be connected to form a snap-fit limit; the anti-slip portion is used to press against the object 2 to be connected to form a friction limit.

[0038] In this embodiment, the limiting portion 3 is provided on the first abutting surface 11 ; and the anti-slip portion is provided on the second abutting surface 12 .

[0039] The limiting portion 3 is a rod body; the limiting portion 3 includes a limiting surface and a guide surface; a limiting hole 21 is formed on the body to be connected 2; the limiting surface is used to abut against the limiting hole 21; the guide surface is used to facilitate the insertion of the limiting portion 3 into the limiting hole 21. There are multiple limiting portions 3, and the multiple limiting portions 3 are distributed in a circular array along the center line of the gasket body 1. The anti-slip portion is formed by providing a plurality of recessed depressions or a plurality of protruding drum points on the second abutting surface 12. Preferably, the anti-slip portion is formed by providing a plurality of recessed depressions on the second abutting surface 12, and the anti-slip portion is formed by grinding the second abutting surface 12 with sandpaper. The limiting portion 3 is a rod body.

[0040] By adopting the above solution, the limiting portion 3 on the gasket body 1 plays a role in preventing the gasket body 1 from rotating relative to the connecting body 2. Therefore, after the nut portion of the bolt presses the gasket body 1, the gasket body 1 is fixed relative to the connecting body 2; and the anti-slip portion on the gasket body 1 can prevent the bolt from rotating relative to the gasket body 1 after the nut portion of the bolt presses the gasket body 1, thereby achieving the fastening of the gasket body 1 to the connecting body 2 and the fastening of the gasket body 1 to the nut portion of the bolt. In some usage scenarios, if the connecting body 2 to be connected by the bolt and the gasket vibrates, the relative rotation between the bolt and the connecting body 2 can be avoided by setting the limiting portion 3 and the anti-slip portion, thereby avoiding the loosening between the bolt and the connecting body 2 after the bolt rotates, greatly improving the tightness and stability of the connection.

[0041] Example 2

[0042] Based on Example 1, the gasket body 1 further includes: a first connecting surface 13 and a second connecting surface 14; the first connecting surface 13 is used to connect the inner ring of the first abutting surface 11 with the inner ring of the second abutting surface 12; the second connecting surface 14 is used to connect the outer ring of the first abutting surface 11 with the outer ring of the second abutting surface 12; the first connecting surface 13 and the second abutting surface 12 are both arcuate surfaces. The provision of the arcuate surfaces allows the edge of the gasket body 1 to form a smooth transition surface, preventing the edge of the gasket from easily rubbing or scratching the hand.

[0043] Example 3

[0044] Based on the embodiment 1, the position limiting portion 3 includes a first clamping portion 31 and a second clamping portion 32. The first clamping portion 31 and the second clamping portion 32 are both rods. The first clamping portion 31 and the second clamping portion 32 are fixedly connected together.

[0045] The limiting groove 22 is formed on the body to be connected 2. The first clamping portion 31 is fixed to the first abutting surface 11, and the second clamping portion 32 is fixed to the first clamping portion 31. The second clamping portion 32 can be bent relative to the first clamping portion 31. The limiting groove 22 is used for the first clamping portion 31 and the second clamping portion 32 to be inserted. When the bolt is connected to the body to be connected 2, the gasket body 1 is located between the nut portion of the bolt and the body to be connected 2; the second clamping portion 32 is bent relative to the first clamping portion 31, and when the nut portion of the bolt is pressed against the gasket body 1, the second clamping portion 32 is pressed against the screw portion of the bolt.

[0046] One example of how the second clamping portion 32 can be bent relative to the first clamping portion 31 is when the first clamping portion 31 is a rigid rod and the second clamping portion 32 is a rod that can be elastically deformed and bent. Another example is when both the first clamping portion 31 and the second clamping portion 32 are rigid rods and are connected together via a coupling that can be elastically deformed and bent. Preferably, the first clamping portion 31 is a rigid rod and the second clamping portion 32 is a rod that can be elastically deformed and bent.

[0047] The first clamping portion 31 and the second clamping portion 32 are fixed by welding, gluing, and threaded fitting.

[0048] The second clamping portion 32 is bent relative to the first clamping portion 31, thereby creating a shallow groove on the connecting body 2 to accommodate more limiting portions 3, improving the limiting effect. Furthermore, since the shallow groove on the connecting body 2 does not damage the mechanical properties of the connecting body 2, it can better protect the connecting body 2. After the second clamping portion 32 is bent relative to the first clamping portion 31, the second clamping portion 32 abuts against the screw portion of the bolt, thereby limiting the second clamping portion 32 to the screw portion and preventing the screw portion from rotating. Since the second clamping portion 32 is inserted into the limiting groove 22, the second clamping portion 32 cannot rotate relative to the connecting body, thus being fixed and unable to rotate. Therefore, the second clamping portion 32 can further prevent the screw portion from rotating. Since the second clamping portion 32 is bent due to the compression of the nut gasket, the closer the screw portion is screwed to the thread groove, the greater the degree of bending of the second clamping portion 32, and the greater the pressure of the second clamping portion 32 against the screw portion, thereby achieving a self-locking effect. When the second clamping portion 32 is bent and deformed, the second clamping portion 32 will generate resistance to the bending deformation, and before the bending deformation of the second clamping portion 32 reaches the bending moment yield limit, if the second clamping portion 32 loses the force, partial rebound deformation will occur, so that the second clamping portion 32 generates a reaction force on the gasket body 1 through the first clamping portion 31, thereby forming a larger pre-tightening force required for the threaded connection between the screw portion and the threaded hole.

[0049] As a further preferred solution of this embodiment, based on the above content, the second clamping portion 32 is used to form the anti-slip portion on the surface that abuts against the screw portion of the bolt. The anti-slip portion has the same structure as that in the above embodiment.

[0050] In some other embodiments, the gasket body 1 is a plate body with elastic deformation ability formed by reverse twisting of at least two sides under force. Therefore, after the gasket body 1 is squeezed and deformed, it can provide pre-tightening force for the threaded connection between the screw portion and the threaded hole, which is part of the effect of an elastic gasket.

[0051] The above description is only an illustration of some preferred embodiments of the present disclosure and the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
