Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-3, the utility model provides a sealing anti-loosening gasket, including gasket 1, first rubber circle 2 and second rubber circle 3, gasket 1's double-phase opposite side wall centre of a circle position has all run through and has seted up through-hole 11, first annular spacing groove 12 has been seted up to the interior pore wall of through-hole 11, fixed mounting has first rubber circle 2 in first annular spacing groove 12, second annular spacing groove 13 has been seted up to gasket 1's outer rampart, gasket 1's outer rampart cover is equipped with second rubber circle 3, second rubber circle 3's inner rampart fixed mounting has annular rubber circle 31, annular rubber circle 31 embedding fixed mounting is in second annular spacing groove 13, the thickness of second rubber circle 3 is greater than gasket 1's thickness.

Wherein, gasket 1 is made for metal steel material, guarantees that gasket 1 is whole rigidity stable.

Wherein, the width of first rubber circle 2 is greater than the groove depth of first annular spacing groove 12 to the inner circle of first rubber circle 2 is that radius edge handles, guarantees that first rubber circle 2 installs firmly, and when the installation with the sliding friction of screw rod little.

The groove width of the first annular limiting groove 12 is equal to the thickness of the first rubber ring 2 and is smaller than the thickness of the gasket 1.

The groove width of the second annular limiting groove 13 is equal to the thickness of the annular rubber ring 31 and is smaller than the thickness of the gasket 1, so that the annular rubber ring 31 is ensured to be firmly installed.

Wherein, the two opposite side walls of the gasket 1 are both provided with anti-skid grains, and the two anti-skid grains are radial and centripetal, so that the friction force when the gasket 1 is contacted is increased.

The working principle is as follows:

firstly, the first rubber ring 2 is fixedly installed at the central through hole 11 of the sealing anti-loosening gasket in an embedded mode, and the inner ring of the first rubber ring 2 is processed by the inverted edge, so that the outer wall of a screw can be fully attached to screws with different outer diameters, large sliding friction cannot be generated between the screw and the screw, and the gasket can be conveniently installed on the premise that good sealing performance is preliminarily guaranteed;

secondly, this sealed locking gasket has second rubber circle 3 at gasket 1's outer rampart embedding fixed mounting, second rubber circle 3 realizes the embedding fixed mounting with gasket 1 through annular rubber circle 31 and the spacing cooperation of second annular spacing groove 13, the thickness of second rubber circle 3 will be greater than gasket 1's thickness, this is just so that gasket 1 when the installation, second rubber circle 3 can at first be extruded, by extruded second rubber circle 3 has elastic restoring force, utilize elastic restoring force can conflict bolt structure again, make gasket 1 difficult by the extrusion lead to warping, just also guarantee gasket 1 and can not appear the inhomogeneous problem of atress when being extruded.
