Description

Technical Field

[0001] This application relates to the field of gaskets for threaded connections, and more particularly, to an anti-slip gasket. Background Art

[0002] A gasket is used between a bolt and a nut, and can also be used on a screw and some connecting bodies with threaded holes.

[0003] One type of gasket is an elastic gasket. By pressing the nut of the bolt on the gasket to cause elastic deformation of the gasket, the force exerted on the nut of the bolt away from the nut or the connecting body is increased, that is, the pre-tightening force of the threaded connection is increased.

[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 between the bolt and the nut and the connecting body. Long-term use will affect the stable effect of the threaded connection and cause the connection to become loose. Summary of the Utility Model

[0005] The content part of this application is used to briefly introduce the concepts, which will be described in detail in the following specific implementation part. The content part of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0007] By adopting the above solution, the setting of the turning surface is to make the two abutting surfaces of the gasket be squeezed to cause deformation of the gasket, thereby increasing the pressure between the gasket and the bolt and the nut or the connecting body, and achieving the effect of increasing the pre-tightening force required for the threaded connection. In addition, the setting of the anti-slip portion on at least one of the abutting surfaces can help increase the friction between the bolt and the gasket, making it difficult for the bolt to rotate relative to the nut or the connecting body, thereby greatly improving the connection effect and stability in the threaded connection.

[0008] Further, the anti-slip portion is formed by opening a plurality of grooves on the abutting surface.

[0009] Further, an anti-slip portion is formed on one of the two abutting surfaces; a friction portion is formed on the other abutting surface.

[0010] Further, a plurality of the grooves are circumferentially and arrayedly distributed along the axis of the anti-slip gasket.

[0011] Further, the friction part is formed by a plurality of concave pits or a plurality of convex bumps formed on the abutting surface.

[0012] Further, the turning surface is a plane.

[0013] Further, the turning surface is a curved surface.

[0014] Further, the groove includes: a first groove, a second groove and a partition part; the partition part is located between the first groove and the second groove; a friction surface flush with the abutting surface is formed on the partition part.

[0015] Further, a plurality of abutting parts are formed in the middle of the anti-slip gasket; the abutting parts are fixed to the anti-slip gasket.

[0016] Further, the abutting part can be bent and deformed by external interference.

[0017] The beneficial effect of the present application is that: the anti-slip part on the gasket is used to increase the frictional force between the bolt and the gasket, thereby increasing the anti-rotation effect between the bolt and the gasket. In addition, the turning surface is provided to provide a pre-tightening force for the threaded connection of the bolt by the gasket, so that the connection effect can be increased by increasing the pre-tightening force and the connection stability can be increased by preventing relative rotation.

[0032] The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0033] Refer to Figures 1-5 ,

[0034] An anti-slip gasket, the anti-slip gasket is formed with two abutting surfaces. The abutting surfaces are the end faces of the anti-slip gasket. At least one of the two abutting surfaces is formed with an anti-slip portion; at least one smooth surface and at least one turning surface are formed on the abutting surface; at least one of the smooth surfaces is connected end to end through the turning surface; the smooth surface is perpendicular to the axis of the anti-slip gasket; the turning surface is inclined to the axis of the anti-slip gasket.

[0035] In this embodiment, anti-slip portions are provided on both abutting surfaces. The smooth surface is a smooth plane. The anti-slip portion is formed by opening a plurality of grooves on the abutting surface. The plurality of grooves are circumferentially and arrayedly distributed along the axis of the anti-slip gasket.

[0036] By adopting the above solution, the setting of the turning surface is such that when the two abutting surfaces of the gasket are squeezed, the gasket will deform, thereby increasing the pressure between the gasket and the bolt and nut or the connecting body, and achieving the effect of increasing the pre-tightening force required for the threaded connection. In addition, the setting of the anti-slip portion on at least one abutting surface can help increase the friction force between the bolt and the gasket, making it difficult for the bolt to rotate relative to the nut or the connecting body, thus greatly improving the connection effect and stability in the threaded connection.

[0037] In some embodiments, an anti-slip portion is formed on one of the two abutting surfaces; a friction portion is formed on the other abutting surface. The friction portion is formed by forming a plurality of concave pits or a plurality of convex bumps on the abutting surface. Preferably, the friction portion is formed by a plurality of concave pits. The friction portion is formed by rubbing a piece of sandpaper on the abutting surface for a period of time.

[0038] Since the anti-slip portion is formed by opening grooves, one abutting surface has grooves opened, and the other abutting surface forms a friction portion. On the one hand, it can increase the friction force of the two abutting surfaces, further prevent the bolt from rotating, and improve the fixing effect. On the other hand, it can further reduce the thickness of the gasket so that its thickness only needs to accommodate the grooves on one side, and the application is more space-saving after the thickness is reduced.

[0039] The turning surface is a plane or the turning surface is a curved surface. In this embodiment, the turning surface is formed by twisting the anti-slip gasket. Further preferably, there are two smooth surfaces and two turning surfaces.

[0040] In some other embodiments, the groove includes: a first groove, a second groove, and a separating portion. The separating portion is located between the first groove and the second groove; a friction surface flush with the abutting surface is formed on the separating portion. The friction surface is the same as the friction portion. In this embodiment, the groove is formed by a circular saw feeding downward a certain distance at the positions of the first groove and the second groove on the gasket. The setting of the first groove and the second groove increases the number of grooves and can further enhance the anti-slip effect.

[0041] In some other embodiments, a plurality of abutting portions are formed in the middle of the anti-slip gasket; the abutting portions are fixed to the anti-slip gasket. The abutting portions can be bent and deformed by external interference. The abutting portions are metal plates with toughness. When the threaded rod is inserted into the hole position in the middle of the anti-slip gasket, the abutting portions are deformed so that the threaded rod can be normally inserted, and then the abutting portions will closely fit on the threaded rod, further enhancing the effect of preventing relative rotation between the threaded rod and the anti-slip gasket.

[0042] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. 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 technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) disclosed in the embodiments of the present disclosure that have similar functions.
