Description

Technical Field

[0001] The utility model belongs to the technical field of gaskets, and in particular relates to an anti-loosening gasket for a hexagonal head fastener. Background Art

[0002] There are three main methods to prevent bolts from loosening: friction anti-loosening, mechanical anti-loosening, and permanent anti-loosening. Friction anti-loosening has a certain anti-loosening effect but is unreliable. Mechanical anti-loosening methods are reliable but have limited usage and cumbersome operations. Permanent anti-loosening methods usually require the destruction of threads during disassembly, and fasteners cannot be reused. Different forms are suitable for different occasions.

[0003] In the prior art, mechanical anti-loosening is the most widely used, but it generally requires slotting or drilling holes on the fasteners before use, which is complicated to operate and has low work efficiency. Utility Model Content

[0007] Furthermore, the bending portion is at least one lower flange, and the lower flange is arranged perpendicular to the gasket body.

[0008] Furthermore, the bending portion includes an upper flange and a lower flange, the upper flange is arranged obliquely with respect to the gasket body, and the lower flange is arranged perpendicularly with respect to the gasket body.

[0009] Furthermore, the upper flange and the lower flange are arranged opposite to each other.

[0010] Furthermore, the bending portion is fixedly connected to or integrally arranged with the gasket body.

[0011] Furthermore, the inclination angle between the upper flange and the gasket body is 120°-150°.

[0012] Furthermore, the inclination angle between the upper flange and the gasket body is 135°.

[0013] Furthermore, at least one of the upper flange and the lower flange is provided and is evenly distributed, and a connecting hole is provided on an edge of the upper flange away from the gasket body.

[0014] Beneficial effects of the utility model:

[0015] The anti-loosening gasket for the hexagonal head fastener provided by the utility model is easy to manufacture, has a simple structure, is easy to disassemble and assemble, does not require slots or holes to be opened on the sides of the bolts or nuts, and optimizes the installation process of the fasteners; it is suitable for installation in the countersunk position, takes into account the anti-loosening function and the beautiful appearance, and provides a perfect solution for the working conditions of vibration and fluid scouring.

[0019] The utility model provides an anti-loosening gasket for a hexagonal head fastener. The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings to make it easier to understand and grasp.

[0020] Example 1

[0021] refer to Figure 1 A locking gasket for a hexagonal head fastener comprises a gasket body 1, a through hole 2 is provided in the middle of the gasket body 1, and a bending portion is provided on the gasket body 1.

[0022] In this embodiment, the bending portion includes an upper flange 4 and a lower flange 3. The upper flange 4 is inclined to the gasket body 1, and the lower flange 3 is vertically arranged to the gasket body 1. The combination of the upper flange 4 and the upper flange 3 better limits the movement of the gasket body 1 and makes the connection more reliable.

[0023] In this embodiment, the upper flange 4 and the lower flange 3 are preferably one and are arranged opposite to each other.

[0024] In this embodiment, the bending portion and the gasket body 1 are integrated into one, which is simple and convenient.

[0025] In this embodiment, the inclination angle between the upper flange 4 and the gasket body 1 is 135°.

[0026] In this embodiment, a connection hole is provided on an edge of the upper flange 4 away from the gasket body 1 .

[0027] When the utility model is used, Figure 2As shown, the first fastener 6 is connected to the second fastener 7 by the fastener 8, the lower flange 3 is perpendicular to the gasket body 1, and the lower flange 3 extends into the pin hole of the first fastener 6 to limit the movement of the gasket body 1. The upper flange 4 is inclined 135° to the gasket body 1. After the bolts are tightened, the upper flange 4 uses the connecting hole 5 to lift the bevel of the upper flange 4 so that it is close to one side of the fastener, which echoes the lower flange 3 to further limit the movement of the gasket body 1.

[0028] Example 2

[0029] A locking gasket for a hexagonal head fastener comprises a gasket body 1, a through hole 2 is arranged in the middle of the gasket body 1, and a bending portion is arranged on the gasket body 1.
