Description

High-performance locking nut for automobile

Technical Field

The utility model relates to a nut technical field specifically is a high performance lock nut for car.

Background

The nut is also called as a nut, and is a fixing tool, the center of the nut is provided with a hole, the inner side of the hole is provided with threads, the nut is often shared with screws with the same size to fix a relevant joint part, if the nut is loosened by environmental factors such as vibration and the like, the relevant part can be further reinforced by using tools such as glue or pins and the like, the nut is hexagonal in shape, and then the nut is square;

the existing nuts for engineering vehicles and automobiles are generally standard nuts, the outer surface of a nut body of the standard nut is generally designed to be a plane, the nut body cannot achieve a fastening effect when being matched with parts, and the nut is easy to loosen and cause defects in use.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a high performance lock nut for car to propose current machineshop car, the nut for car in solving above-mentioned background art, generally be standard nut, the surface of the nut body of this standard nut designs for the plane usually, can't play the fastening effect when mutually supporting with spare part, and leads to the easy not hard up problem of nut.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a high performance lock nut for car, includes the bolt, the gasket has been cup jointed in the bolt upper end outside, gasket upper end surface is provided with the through-hole, the gasket up end is provided with the second helicoid, the gasket upper end is provided with the nut, nut threaded connection is on bolt outside surface, the terminal surface is provided with first helicoid under the nut.

Preferably, the diameter of the through hole is larger than that of the threaded connection part of the bolt.

Preferably, the washer is a hexagonal washer and the diameter of the washer is larger than that of the nut.

Preferably, the first helicoid and the second helicoid are matched with each other.

Preferably, the bolt is of an inverted T-shaped structure, and the lower end face of the bolt is of a hexagonal structure.

Compared with the prior art, the beneficial effects of the utility model are that: this high performance lock nut for car is through being provided with the gasket and be provided with the second helicoid at the up end of gasket and be provided with the first helicoid at the lower terminal surface of nut and utilize the structure that the helicoid between nut and the gasket coincide, the theoretical application of self-tightening force has been realized, and with specific lift angle, reach the effect of locking taking off completely, the vice stability of connection has not only been increased, it is first that the most stress of back stress is concentrated after also having avoided the nut to screw up simultaneously, the disappearance of the traditional fastener on the two teeth, thereby make stress evenly distributed, not only the bearing capacity of nut and bolt has been promoted greatly, and the damage degree of interior external screw thread has also been reduced, thereby it is not hard up to be fine prevent that high performance lock nut for car from moving.

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.

Referring to fig. 1-3, the present invention provides a technical solution: a high-performance locking nut for an automobile comprises a bolt 1, wherein the bolt 1 is of an inverted T-shaped structure, the lower end face of the bolt 1 is of a hexagonal structure, a wrench is convenient to drive the bolt 1 to rotate, a gasket 2 is sleeved on the outer side of the upper end of the bolt 1, a through hole 6 is formed in the surface of the upper end of the gasket 2, the diameter of the through hole 6 is larger than that of a threaded connection portion of the bolt 1, when the gasket 2 is installed, the gasket 2 can be directly sleeved on the outer side of the connection portion of the bolt 1, the gasket 2 is of a hexagonal structure, the diameter of the gasket 2 is larger than that of a nut 3, when the nut 3 is disassembled, the gasket 2 can be conveniently screwed by the wrench to rotate, so that the nut 3 rotates along with the gasket, a second spiral face 5 is arranged on the upper end face of the gasket 2, a nut 3 is arranged on the upper end of the gasket 2, the nut 3 is in threaded connection with the surface of the outer side of the bolt 1, a first spiral face 4 is arranged on the lower end face of the nut 3, the first spiral surface 4 and the second spiral surface 5 are mutually matched, so that the nut 3 is convenient to be matched with the gasket 2.

The working principle is as follows: by arranging the gasket 2, arranging the second spiral surface 5 on the upper end surface of the gasket 2 and arranging the first spiral surface 4 on the lower end surface of the nut 3, when the nut 3 is fixed, firstly, the gasket 2 is sleeved on the bolt 1, then, the nut 3 is screwed to ensure that the first spiral surface 4 is matched with the second spiral surface 5, the application of the self-tightening force theory is realized, and the anti-loosening effect is completely achieved by a specific lifting angle, thereby not only increasing the stability of a coupling pair, but also avoiding the defect that most of the stress is concentrated on the traditional fasteners on the first and second teeth after the nut 3 is screwed, further ensuring that the stress is uniformly distributed, greatly improving the bearing capacity of the nut 3 and the bolt 1, reducing the damage degree of the inner and outer threads, and clamping the gasket 2 of the movable wrench when the nut 3 is dismounted, the washer 2 is rotated, and the nut 3 is driven to rotate by the rotating washer 2, so that the nut 3 is detached.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
