Description

Anti-loosening fastening nut gasket suite

Technical Field

The utility model belongs to the technical field of fasteners, and particularly relates to a locknut gasket suite.

Background

The fastener is a mechanical part which is used for fastening connection and has wide application, the fastener has wide application industry, various fasteners can be seen on various machines, equipment, vehicles, ships, railways, buildings and the like, and the fastener is a mechanical basic part which has the widest application. The nut and the gasket are usually matched with the bolt to form a fastener, the fastening structure is that the bolt is inserted in the connecting piece, the gasket is sleeved on the other end of the bolt, and the bolt is screwed and fixed through the threaded connection of the nut and the bolt. Because nut and gasket structure are simpler, its and bolt cooperation only play fixed effect through simple threaded connection, under high temperature or high-frequency vibration impact, lead to the screw thread inclined plane between nut, bolt to slide each other easily, and then take place to become flexible, cause the incident, consequently, need design a nut gasket that can locking up and avoid becoming flexible the potential safety hazard that produces.

Disclosure of Invention

The utility model aims to provide a check fastening nut gasket suite which is convenient to install, anti-loose and high in fastening performance aiming at the defects in the prior art.

In order to achieve the technical purpose, the anti-loose fastening nut gasket kit adopts the technical scheme that:

the utility model provides a locking fastening nut gasket external member, includes nut body and gasket body, nut body both ends are equipped with the lug respectively, and inside is equipped with along the axially extended screw hole, both sides lug connecting wire and nut body internal diameter are in same water flat line, the lug both sides are embedded respectively has first magnetic path, gasket body surface is equipped with the centre bore, the centre bore intussuseption is filled with to the bellied taper rubber inner circle in gasket body surface, makes the radial cross-section of rubber inner circle is the U-shaped structure, the nut body surface is located through centre bore cover to the gasket body, makes the lug closely contradict rubber inner circle inner wall, rubber inner circle and lug conflict department are embedded have the second magnetic path with first magnetic path actuation mutually.

Preferably, the surface of the nut body is provided with an annular boss, and the annular boss is communicated with the threaded hole.

Preferably, the gasket body is of a disc-shaped structure, and the outer side of the gasket body is annularly provided with the anti-loosening teeth along the circumferential direction.

Preferably, the locking teeth are curved and convex toward the fastening direction of the nut body.

Preferably, the bump is a triangular prism, and the inner edge of the triangular prism is sewed with the inner ring of the nut body.

Compared with the prior art, the utility model has the beneficial effects that:

in the process of screwing the nut body and the gasket body, the convex block tightly props against the rubber inner ring, and the connecting line of the convex block is consistent with the inner diameter of the nut body, so that the nut body is vertically locked and matched, and the installation convenience is improved; the gasket body is internally provided with the rubber inner ring, and the first magnetic block and the second magnetic block are matched with each other in attraction, so that the problem that the nut body and the gasket body rotate relatively in the vibration process and are further loosened is effectively prevented; the locking teeth on the periphery of the gasket body are utilized to enable the nut gasket set to stably bite the contact end face, and the stability of the nut gasket set is improved.

FIG. 2 is a schematic view of the construction of the gasket body of the present invention;

FIG. 3 is a schematic structural diagram of a bump according to the present invention;

fig. 4 is a schematic structural view of the nut body of the present invention.

In the figure: 1. a nut body; 2. a gasket body; 3. a bump; 4. a threaded hole; 5. a first magnetic block; 6. a rubber inner ring; 7. a second magnetic block; 8. an annular boss; 9. locking tooth.

Detailed Description

The utility model will be further described with reference to the following drawings and detailed description:

as shown in fig. 1-4, an anti-loosening fastening nut gasket external member comprises a nut body 1 and a gasket body 2, two ends of the nut body 1 are respectively provided with a convex block 3, a threaded hole 4 extending along the axial direction is formed in the nut body, connecting lines of the convex blocks 3 on two sides and the inner diameter of the nut body 1 are located on the same horizontal line, first magnetic blocks 5 are embedded in two sides of the convex block 3 respectively, a central hole is formed in the surface of the gasket body 2, a conical rubber inner ring 6 protruding to the surface of the gasket body 2 is filled in the central hole, the radial cross section of the rubber inner ring 6 is of a U-shaped structure, the surface of the nut body 1 is sleeved with the gasket body 2 through the central hole, the convex block 3 tightly abuts against the inner wall of the rubber inner ring 6, and a second magnetic block 7 attracted with the first magnetic blocks 5 is embedded in the abutting part of the rubber inner ring 6 and the convex block 3.

The surface of the nut body 1 is provided with an annular boss 8, and the annular boss 8 is communicated with the threaded hole 4. Through setting up annular boss 8, make nut body 1 embolia the centre bore rapidly, the installation of nut body 1 and gasket body 2 of being convenient for.

The gasket body 2 is of a disc-shaped structure, the outer side of the gasket body is annularly provided with locking teeth 9 along the circumferential direction, and the locking teeth 9 are bent and protruded towards the fastening direction of the nut body 1. Utilize locking tooth 9 inseparable interlock contact terminal surface, produce in the avoiding use and remove, and then lead to the fastening to descend, take place not hard up problem.

The convex block 3 is a triangular prism, and the inner edge of the triangular prism meets the inner ring of the nut body 1. The convex block 3 is arranged on the inner diameter edge of the nut body 1 to strengthen the connection strength of the center of the nut body 1.
