Description

Technical Field

[0001] This utility model relates to the field of anti-loosening washers, specifically an anti-loosening washer for screws. Background Technology

[0002] Anti-loosening washers, also known as locking washers or self-locking washers, are common mechanical fasteners primarily used to prevent loosening of threaded or axial connections. They are widely used in mechanical connections across various fields, such as automotive engines, suspension systems, braking systems, precision connectors in electronic equipment, and connectors in various industrial machinery. In these applications, anti-loosening washers effectively absorb vibration and impact forces, ensuring the reliability and stability of the connection.

[0003] However, while existing anti-loosening washers can effectively prevent screws from loosening, they rely solely on the pre-tightening force of the washers for anti-loosening during use. They are prone to failure due to vibration, lack other safety measures, and have insufficient anti-loosening capabilities. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-loosening washer for screws to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screw anti-loosening washer, comprising a lower layer and an upper layer, wherein the upper layer and the lower layer are arranged on opposite sides, and the contact positions of the upper layer and the lower layer are both roughened.

[0006] As a further embodiment of this utility model: a screw anti-loosening washer, roughly configured including a lower friction layer and an upper protruding layer, wherein the lower friction layer is fixedly connected to the lower layer and the upper protruding layer is fixedly connected to the upper layer.

[0007] As a further embodiment of this utility model: a screw anti-loosening washer, wherein the upper layer is flat on the side near the lower layer, and the lower layer is inclined on the side near the upper layer.

[0008] As a further embodiment of this utility model: a screw anti-loosening washer, the inclined surface is provided with an inclined area, a top contact area and a bottom contact area, one end of the inclined area is fixedly connected to the top contact area, the other end of the inclined area is fixedly connected to the bottom contact area, and the inclined area, the top contact area and the bottom contact area are all movably connected to the upper layer.

[0009] As a further embodiment of this utility model: a screw anti-loosening washer, wherein the outer sides of both the lower and upper layers are fixedly connected with a number of protrusions.

[0010] As a further embodiment of this utility model: a screw anti-loosening washer, wherein the inclined area intersects with the extension line of the upper layer at an angle, the degree of the angle being 3-5°.

[0011] As a further embodiment of this utility model: a screw anti-loosening washer, wherein the outer edges of the lower and upper layers are provided with washer edges, and a convex ball is fixedly connected to one side of the washer edge.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Because the upper and lower layers are designed with opposite surfaces—specifically, the upper layer is planar on the side closest to the lower layer, and the lower layer is inclined on the side closest to the upper layer—and the inclined surface includes an inclined area, a top contact area, and a bottom contact area, one end of the inclined area is fixedly connected to the top contact area, and the other end of the inclined area is fixedly connected to the bottom contact area. The inclined area, top contact area, and bottom contact area are all movably connected to the upper layer. Therefore, when the screw and the connected object compress the anti-loosening washer, the planar surface of the upper layer and the inclined surface of the lower layer will squeeze and stretch the screw and the connected object axially, allowing the screw thread and the connected object thread to fit tightly together, achieving a good anti-loosening effect.

[0014] 2. Because the contact points of the upper and lower layers are both roughened, the roughening includes a lower friction layer and an upper protruding layer. The lower friction layer is fixedly connected to the lower layer, and the upper protruding layer is fixedly connected to the upper layer. Several protrusions are fixedly connected to the outer sides of both the lower and upper layers. At the same time, a gasket edge is provided at the outer edge of both the lower and upper layers. A convex ball is fixedly connected to one side of the gasket edge. Therefore, the gasket can provide good friction when it comes into contact with the screw or the connected object, further improving the anti-loosening performance of the gasket.

The embodiments of this utility model will be described below based on its overall structure.

[0023] In this embodiment of the utility model, a screw anti-loosening washer includes a lower layer 1 and an upper layer 2, wherein the upper layer 2 and the lower layer 1 are arranged on opposite sides, and the contact positions of the upper layer 2 and the lower layer 1 are both roughened.

[0024] Because the upper layer 2 and the lower layer 1 are arranged on opposite sides, specifically, the side of the upper layer 2 closest to the lower layer 1 is a flat surface, and the side of the lower layer 1 closest to the upper layer 2 is an inclined surface. The inclined surface includes an inclined area 11, a top contact area 12, and a bottom contact area 13. One end of the inclined area 11 is fixedly connected to the top contact area 12, and the other end of the inclined area 11 is fixedly connected to the bottom contact area 13. The inclined area 11, the top contact area 12, and the bottom contact area 13 are all movably connected to the upper layer 2. Therefore, when the screw and the connected object compress the anti-loosening washer, the flat surface of the upper layer 2 and the inclined surface of the lower layer 1 will squeeze and stretch the screw and the connected object axially, so that the threads of the screw and the threads of the connected object can fit tightly, achieving a good anti-loosening effect.

[0025] Since the contact points between the upper layer 2 and the lower layer 1 are both roughened, the roughening includes a lower friction layer 3 and an upper protruding layer 4. The lower friction layer 3 is fixedly connected to the lower layer 1, and the upper protruding layer 4 is fixedly connected to the upper layer 2. Several protrusions 6 are fixedly connected to the outer sides of both the lower layer 1 and the upper layer 2. At the same time, a gasket edge 7 is provided at the outer edge of both the lower layer 1 and the upper layer 2. A convex ball 8 is fixedly connected to one side of the gasket edge 7. Therefore, the gasket can provide good friction when it comes into contact with the screw or the connected object, which further improves the anti-loosening performance of the gasket.

[0026] As a further embodiment of this utility model: a screw anti-loosening washer, which is roughly configured to include a lower friction layer 3 and an upper protruding layer 4, wherein the lower friction layer 3 is fixedly connected to the lower layer 1, and the upper protruding layer 4 is fixedly connected to the upper layer 2.

[0027] As a further embodiment of this utility model: a screw anti-loosening washer, wherein the upper layer 2 is flat on the side near the lower layer 1, and the lower layer 1 is inclined on the side near the upper layer 2.

[0028] As a further embodiment of this utility model: a screw anti-loosening washer, the inclined surface is provided with an inclined area 11, a top contact area 12 and a bottom contact area 13, one end of the inclined area 11 is fixedly connected to the top contact area 12, the other end of the inclined area 11 is fixedly connected to the bottom contact area 13, and the inclined area 11, the top contact area 12 and the bottom contact area 13 are all movably connected to the upper layer 2.

[0029] As a further embodiment of this utility model: a screw anti-loosening washer, wherein the outer sides of both the lower layer 1 and the upper layer 2 are fixedly connected with a number of protrusions 6.

[0030] As a further embodiment of this utility model: a screw anti-loosening washer, wherein the inclined area 11 intersects the extension line of the upper layer 2 at an angle 5, the angle 5 being 3-5°.

[0031] As a further embodiment of this utility model: a screw anti-loosening washer, wherein the outer edges of the lower layer 1 and the upper layer 2 are provided with washer edges 7, and a convex ball 8 is fixedly connected to one side of the washer edge 7.

[0032] The working principle of this utility model is as follows: Since the upper layer 2 and the lower layer 1 are arranged in opposite directions, specifically, the side of the upper layer 2 near the lower layer 1 is a flat surface, and the side of the lower layer 1 near the upper layer 2 is an inclined surface. The inclined surface includes an inclined area 11, a top contact area 12, and a bottom contact area 13. One end of the inclined area 11 is fixedly connected to the top contact area 12, and the other end of the inclined area 11 is fixedly connected to the bottom contact area 13. The inclined area 11, the top contact area 12, and the bottom contact area 13 are all movably connected to the upper layer 2. Therefore, when the screw and the connected object compress the anti-loosening washer, the flat surface of the upper layer 2 and the inclined surface of the lower layer 1 will squeeze and stretch the screw and the connected object axially, so that the threads of the screw and the threads of the connected object can fit tightly, achieving a good anti-loosening effect.

[0033] Since the contact points between the upper layer 2 and the lower layer 1 are both roughened, the roughening includes a lower friction layer 3 and an upper protruding layer 4. The lower friction layer 3 is fixedly connected to the lower layer 1, and the upper protruding layer 4 is fixedly connected to the upper layer 2. Several protrusions 6 are fixedly connected to the outer sides of both the lower layer 1 and the upper layer 2. At the same time, a gasket edge 7 is provided at the outer edge of both the lower layer 1 and the upper layer 2. A convex ball 8 is fixedly connected to one side of the gasket edge 7. Therefore, the gasket can provide good friction when it comes into contact with the screw or the connected object, which further improves the anti-loosening performance of the gasket.
