The utility model achieves the locking and anti-loosening purposes by the double fastening of the thread part and the groove cutting part, namely, by contracting the splayed grooves at the two upper ends to tighten the threads of the internal thread hole; the integral type design, the installation is convenient and fast more.

Description

Double-inclined-surface slot-cutting locknut

Technical Field

The utility model relates to a locknut technical field specifically is a double inclined plane grooving locknut.

Background

At present, all can use the nut when installing on each equipment, because the condition is become flexible and lose easily appears in ordinary standard nut, can also take place stolen incident sometimes, especially the nut on the vehicle still can bring the potential safety hazard if becoming flexible or losing. The standard nut refers to nuts of different specifications which are divided according to different standard numbers. The national standard stipulates the thread size, thread pitch, opposite side size, thickness size and hexagonal thickness of the nut. Generally, in order to prevent the nut from loosening, a spring washer is sleeved on the bolt, and then the nut is screwed on the bolt, so that the friction force between the matching threads of the nut and the bolt is increased by the elastic force of the spring washer, and further the nut is prevented from loosening. The method can well play a role in preventing the nut from loosening, but before the nut is screwed on, the bolt is sleeved with the spring washer, so that the use is troublesome. Therefore, the double-bevel groove-cutting locknut is provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a double inclined plane grooving 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 double inclined plane grooving locknut, includes the nut body, the upper end of nut body is equipped with the splayed recess that falls that is located the internal thread hole both sides at its middle part, the side of nut body is equipped with and is located the splayed grooving under the splayed recess that falls, the lower extreme of nut body is equipped with the nut bottom surface arch.

As a further optimization of the technical scheme, the two groups of inverted V-shaped grooves are positioned on the same straight line, and the straight line penetrates through the circle center of the internal thread hole.

As a further optimization of the technical scheme, the inverted V-shaped grooves are communicated with the corresponding V-shaped cutting grooves, and the angle of each V-shaped cutting groove is 146 degrees.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model achieves the locking and anti-loosening purposes by the double fastening of the thread part and the groove cutting part, namely, by contracting the splayed grooves at the two upper ends to tighten the threads of the internal thread hole; the integral type design, the installation is convenient and fast more.

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. 1-4, the present invention provides a technical solution: the utility model provides a double inclined plane grooving locknut, includes nut body 1, the upper end of nut body 1 is equipped with the splayed recess 2 that falls that is located 5 both sides in its middle part of internal thread hole, the side of nut body 1 is equipped with and is located splayed recess 3 under 2, the lower extreme of nut body 1 is equipped with nut bottom surface arch 4.

Specifically, the two groups of inverted V-shaped grooves 2 are positioned on the same straight line, and the straight line penetrates through the circle center of the internal thread hole 5.

Specifically, the inverted V-shaped groove 2 is communicated with the corresponding V-shaped cutting groove 3, and the angle of the V-shaped cutting groove 3 is 146 degrees.

Specifically, when the double-bevel groove-cutting locknut is used, the double-bevel groove-cutting locknut is doubly fastened with the groove-cutting part through the threaded part, namely, the threads of the internal threaded hole 5 are tightened by contracting the splayed grooves 3 at the two positions of the upper end, so that the purpose of locking and locking is achieved;

the opposite side and the opposite angle of the nut body 1 refer to iso4032, GB/T6170 or DN934 standard system, so that the nut is convenient to install; the slotting part (namely the splayed slotting 3) adopts a mechanical physical process, so that the performance is more stable; the integrated design is adopted, so that the installation is more convenient and faster;

the double-inclined-plane slot-cutting locknut is made of materials which are matched with a use and installation environment, and various materials are released for customers to select, and the double-inclined-plane slot-cutting locknut can be roughly divided into: carbon steels, stainless steels and other materials: the carbon steels all adopt high-quality alloy 40Cr as a base material. Stainless steel 304 was used as the base material. Other classes may be selected according to customer needs.

The processing technology of the double-inclined-plane slotting locknut adopts full numerical control equipment for processing, and the uniformity of product quality is ensured. Structurally, an integrated perfect combination design is adopted. Convenient and fast use and double guarantee.

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.
