Description

Nylon locking nut

Technical Field

The utility model relates to a fastener field, more specifically say, it relates to a nylon lock nut.

Background

When the nut is screwed and matched with the screw rod on the object, in order to improve the tightness of the matching, a gasket ring is generally required to be sleeved on the screw rod, the gasket ring has elasticity, one end of the gasket ring is abutted to the object, and the other end of the gasket ring is abutted to the nut, so that the tightness of the nut screwed on the screw rod can be improved, and the assembly firmness of the assembly nut is improved. Before each assembly, the gasket ring needs to be additionally purchased, and the gasket ring is small in size and easy to lose, so that great trouble is brought to the assembly work of the nut.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a nylon lock nut that fastness is higher after the assembly.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a nylon lock nut, includes parent and lower parent, be equipped with the assembly groove on going up the parent, the assembly groove extends to parent down, it is equipped with annular inner groovy to go up the parent and is close down to be equipped with on the terminal surface of parent, and the opening part of inner groovy is equipped with spacing fender ring, and movable fit has the ring in the inner groovy, be equipped with the spring between the diapire of ring and inner groovy, it has at least three springiness cushioning spare to distribute along the periphery of parent down, springiness cushioning spare's one end is established to be located the inner groovy and is fixed with the ring, and the other end is equipped with gasket one and gasket two, gasket one is buckled outside the axle center of parent towards, is "vertical" shape structure, the inside bending of axle center of parent is gone up to gasket two, is C shape structure, is equidistant distribution between the adjacent springiness.

The utility model discloses further set up to: one end of the lower parent body, which is far away from the upper parent body, is provided with a guide part, the guide part is provided with a through hole which is axially matched with the assembling groove barrel, and one end of the inner wall of the through hole, which is close to the lower parent body, inclines towards the opening.

The utility model discloses further set up to: the upper parent body and the lower parent body are arranged in an integrated structure, and the surfaces of the upper parent body and the lower parent body are covered with an anti-rust layer.

Through adopting above-mentioned technical scheme, the nut just can realize the inseparable cooperation with the price of goods through the elastic buffer spare that self carried when the assembly, promotes the fastness of assembly. The screw rod can be smoothly sleeved with the guide part during assembly, and the assembly efficiency is improved.

Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 2.

A nylon lock nut comprises an upper parent body 1 and a lower parent body 2, wherein an assembly groove 12 is arranged on the upper parent body 1, the assembly groove 12 extends to the lower parent body 2, the upper parent body 1 is close to the end face of the lower parent body 2 and is provided with an annular inner groove 10, a limiting baffle ring is arranged at an opening of the inner groove 10, a circular ring 32 is movably matched in the inner groove 10, a spring 11 is arranged between the circular ring 32 and the bottom wall of the inner groove 10, at least three elastic buffer parts 3 are distributed along the periphery of the lower parent body 2, one end of each elastic buffer part 3 is arranged in the inner groove 10 and fixed with the circular ring 32, a first gasket 30 and a second gasket 31 are arranged at the other end of each elastic buffer part, the first gasket 30 is bent outwards towards the axis of the upper parent body 1 to form a vertical structure, the second gasket 31 is bent inwards towards the axis of the upper parent body 1 to form a C-shaped structure, and adjacent elastic buffer, the length of the elastic buffer 3 is greater than that of the lower parent body 2. The end of the lower parent body 2, which is far away from the upper parent body 1, is provided with a guide part 4, the guide part 4 is provided with a through hole 40 which is axially aligned with the assembling groove 12, and the inner wall of the through hole 40 is inclined towards the opening from the end which is close to the lower parent body 2. The upper parent body 1 and the lower parent body 2 are arranged in an integrated structure, and the surfaces of the upper parent body 1 and the lower parent body 2 are covered with an anti-rust layer.

The nut can be smoothly sleeved on the screw rod of the object through the guide part 4, and the sleeving efficiency is improved. After screwing, the elastic buffer part 3 firstly abuts against the surface of the object and continues to be screwed towards the object, the elastic buffer part 3 is stressed to enable the spring 11 in the inner groove 10 to be in a contraction state, after the spring 11 relieves partial pressure, the C-shaped gasket II 31 is used for buffering pressure, and the gasket I30 can expand the stressed area to enable the stability of the nut during movement to be high. After the nut is screwed, the tightness between the nut and the object can be improved by utilizing the force of the spring 11 and the elastic force of the second gasket 31, and the assembly efficiency can be improved by replacing the gasket ring with the elastic buffer piece 3.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
