[0027] The bolt retainer device provided by the utility model, comprising a gasket, a bolt hole and a rotation-stopping bending body. The bolt hole is provided with at least two, and is all arranged on the gasket. Each bolt hole is provided with a rotation-stopping bending body, and the rotation-stopping bending body is connected with the gasket or is an integral structure with the gasket. In use, after the bolt is screwed through the bolt hole, the rotation-stopping bending body around the bolt hole can be bent and wrapped around the outer circumferential surface of the nut of the bolt, so that the rotation-stopping bending body can be used to limit the rotation of the bolt, thereby preventing the bolt from loosening.

[0028] The bolt hole 200 is provided with at least two, and is all arranged on the gasket 100, in use, the bolt can pass through the gasket 100 after the bolt hole 200 passes through the gasket 100 and is connected with the equipment that needs to be fastened, and then the gasket 100 is located between the equipment and the nut. Moreover, the bolt hole 200 is provided with at least two, when the bolt is screwed and fastened in the bolt hole 200, the gasket 100 can be used to limit the rotation.

[0029] Each bolt hole 200 is provided with a rotation-stopping bending body, and the rotation-stopping bending body is connected with the gasket 100 or is an integral structure with the gasket 100. In use, after the bolt is screwed through the bolt hole 200, the rotation-stopping bending body around the bolt hole 200 can be bent and wrapped around the outer circumferential surface of the nut of the bolt, so that the rotation-stopping bending body can be used to limit the rotation of the bolt, thereby preventing the bolt from loosening.

[0030] In some embodiments, the rotation-stopping bending body can be a bending piece 300, the bending piece 300 can be an integral structure with the gasket 100, and the bending piece 300 extends away from the bolt hole 200 in the radial direction of the bolt hole 200.

[0031] When the bolt is tightened, the bent piece 300 can be bent upwards so that the side of the bent piece 300 close to the nut is attached to the outer circumferential surface of the nut. Since the rotation freedom of the gasket 100 is limited, the bent piece 300 can further limit the loosening rotation of the bolt.

[0032] In some embodiments, the number of bent pieces 300 can be greater than or equal to two, and the bent piece 300 can be provided with a crease line. Since the nut is mostly a regular hexagonal nut, the crease lines of the plurality of bent pieces 300 can be made to coincide with two or more edges of the same regular hexagon, and the center point of the regular hexagon can be located on the axis of the corresponding bolt hole 200.

[0033] For example, two bent pieces 300 can be provided, and the two bent pieces 300 can be arranged adjacently, and the included angle of the crease lines on the two bent pieces 300 can be 120 degrees. When the two bent pieces 300 are bent, the two bent pieces 300 can be attached to two adjacent sides of the nut, thereby limiting the rotation of the bolt.

[0034] In a specific embodiment, the gasket 100 can be a sheet with a thickness of 0.6 mm to 2.0 mm, and the material thereof can be galvanized steel, stainless steel, or aluminum. For example, the gasket 100 can be a rectangular stainless steel sheet with a thickness of 1 mm.

[0035] The bolt hole 200 can be provided in two, and the two bolt holes 200 can be respectively provided at positions close to the two ends of the gasket 100.

[0036] An isosceles triangular notch can be provided at each of the two ends of the gasket 100, and the top angle of the isosceles triangle can be 120 degrees. The corner pieces located on both sides of the isosceles triangular notch form the above-mentioned bent piece 300.
