Description

Novel locknut

Technical Field

The utility model belongs to the technical field of novel locknut, concretely relates to novel locknut.

Background

With the development of industrialization, the use of nuts is very extensive and is spread in various industries, while the conventional nuts cannot meet the fastening requirements of diversified mechanical parts, and the conventional nuts have limited fastening effect and often cause falling-off events due to vibration and the like.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel locknut to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel locknut, includes the nut body, the inside screw hole that is of nut body, threaded hole inner wall is provided with the internal thread, nut body outer wall is provided with the external screw thread, nut body periphery be provided with external screw thread screwed connection's deputy nut.

Preferably, the nut body is a trapezoid structure with a wide upper part and a narrow lower part.

Preferably, the lower end of the nut body is provided with a screwing end.

Preferably, the secondary nut is a trapezoidal structure, and the length of the inner diameter of the narrowest end of the secondary nut is greater than that of the outer diameter of the screwing end.

The utility model discloses a technological effect and advantage: this novel locknut, simple structure, the design is novel, through install a nut structure additional in the nut periphery for the fastening effect of nut is strengthened greatly, reduces the production accident that spare part drops and causes.

Drawings

FIG. 1 is a schematic view of the main structure of the present invention;

fig. 2 is a schematic view of the main structure of the screw-in bolt of the present invention.

In the figure: 1. a threaded hole; 2. an internal thread; 3. a nut body; 4. an external thread; 5. a secondary nut; 6. and screwing the end.

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.

The utility model provides a as shown in fig. 1, fig. 2 novel locknut, including

nut body

3, 3 inside screw holes 1 that are of nut body, 1 inner wall of screw hole is provided with

internal thread

2, 3 outer walls of nut body are provided with

external screw thread

4, 3 peripheries of nut body are provided with the auxiliary nut 5 with 4 screwed connection of external screw thread.

Specifically, the nut body 3 has a trapezoidal structure with a wide top and a narrow bottom.

In particular, the lower end of the nut body 3 is provided as a screwing end 6.

Specifically, the secondary nut 5 has a trapezoidal structure, and the length of the inner diameter of the narrowest end thereof is greater than the length of the outer diameter of the screwing end 6.

The working principle is as follows: this novel locknut, when using, at first rotatory end 6 of revolving revolves screw hole 1 and the bolt threaded connection with nut body 3, screws for the first time, then constantly screws vice nut 5 again, exerts a power of tightening up to nut body 3 for internal thread 2 tightly pastes with the bolt, reduces because of reasons such as vibrations lead to the not hard up of nut.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
