Abstract

The utility model discloses an extrusion type anti-loosening nut which comprises a nut body, wherein a lateral screw hole is formed in the nut body. According to the utility model, the side surface of the nut is punched and tapped to form the side surface screw hole, when the nut body is locked on a bolt or a screw rod and needs to be fastened, the nut body can be screwed by a tool such as a spanner, and then the nut body is locked from the side surface screw hole by the positioning column for locking, so that the nut body can be well fixed. Wherein nut body and bolt itself are through the rotatory tight of same pitch, do not have the possibility of skidding, lock with the reference column from the side again, through the pressure of reference column to the nut, increase the frictional force between nut and bolt or the screw, make the body more difficult rotation, prevent the pine and take off.

Description

Extrusion type anti-loosening nut

Technical Field

The utility model relates to the field of nuts, in particular to an extrusion type anti-loosening nut.

Background

Bolts and nuts are widely used in various fields as a common fastener. When they are applied to objects which are frequently moved and shaken, nuts are easily separated from bolts due to loosening after a long time use, causing problems in product quality or economic loss. Although some existing anti-loosening nuts can achieve locking between bolts and nuts, the existing anti-loosening nuts are often complex in structure, and locking parts of the existing anti-loosening nuts cannot be automatically locked. Therefore, the existing anti-loosening nut is complex in structure and inconvenient to use. Therefore, the extrusion type anti-loosening nut is provided.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, the utility model provides an extrusion type anti-loose nut.

In order to solve the technical problems, the utility model provides the following technical scheme:

the utility model relates to an extrusion type anti-loosening nut which comprises a nut body, wherein a lateral screw hole is formed in the nut body.

As a preferable technical scheme of the utility model, the lateral screw hole is internally threaded with a positioning column.

As a preferable technical scheme of the utility model, the positioning column is provided with an external thread corresponding to the lateral screw hole.

As a preferable technical scheme of the utility model, the outer end part of the positioning column is provided with a functional hole matched with a screwdriver.

As a preferable technical solution of the present invention, a rubber anti-abrasion layer is provided at an inner end portion of the positioning column.

As a preferable technical scheme of the utility model, the surface of the rubber anti-abrasion layer is provided with anti-skidding teeth.

As a preferable technical scheme of the utility model, the depth of the lateral screw hole is greater than the length of the positioning column.

The utility model has the beneficial effects that: this kind of locking nut that moves back of extrusion formula punches in the nut side and attacks tooth formation side screw, can screw up the nut body with instruments such as spanner earlier when locking the nut body on bolt or screw rod need fasten, then reuse reference column is locked into from the side screw and is locked, just so can fix the nut body well. The nut body and the bolt are tightly rotated through the same thread pitch, the possibility of slipping is avoided, the nut body and the bolt are locked by the positioning column from the side, the pressure of the positioning column on the bolt increases the friction force between the nut and the bolt, the nut body is enabled to be less prone to rotating, and loosening is prevented; the falling off of the nut body is effectively prevented; the mounting nut can be easily disassembled, and the nut is fastened by locking the screw into the side face, so that the mounting nut is simple and easy to operate and high in reliability.

Drawings

The accompanying drawings, which are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate embodiments of the utility model and together with the description serve to explain the principles of the utility model and not to limit the utility model. In the drawings:

FIG. 1 is a schematic structural view of an extruded anti-loosening nut of the present invention;

fig. 2 is a schematic view of the assembly of the extrusion type anti-loose nut.

In the figure: 1. a nut body; 2. a lateral screw hole; 3. a positioning column; 4. an external thread; 5. a functional hole; 6. a rubber anti-wear layer; 7. and (4) anti-slip teeth.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Example (b): as shown in fig. 1-2, the extrusion type anti-loosening nut comprises a nut body 1, wherein a lateral screw hole 2 is formed in the nut body 1. And the lateral screw hole 2 is internally threaded with a positioning column 3. The positioning column 3 is provided with an external thread 4 corresponding to the lateral screw hole 2; the outer end part of the positioning column 3 is provided with a functional hole 5 matched with a screwdriver; a rubber anti-abrasion layer 6 is arranged at the inner end part of the positioning column 3; the surface of the rubber anti-wear layer 6 is provided with anti-slip teeth 7, so that an anti-wear and anti-slip effect is achieved, the inner end part of the positioning column 3 is prevented from scratching the bolt, and the nut body is inconvenient to disassemble in the later period; the depth of the lateral screw hole 2 is larger than the length of the positioning column 3, and the positioning column 3 is hidden. The side of the nut is punched and tapped to form a side screw hole, when the nut body 1 is locked on a bolt or a screw rod and needs to be fastened, the nut body 1 can be screwed up by using tools such as a wrench, and then the positioning column 3 is locked in from the side screw hole to be locked, so that the nut body 1 can be well fixed. The nut body 1 and the bolt are tightly rotated through the same thread pitch, the possibility of slipping is avoided, the nut body and the bolt are locked by the positioning column 3 from the side, and the friction force between the nut and the bolt is increased through the pressure of the positioning column 3 on the bolt, so that the nut body is not easy to rotate and is prevented from loosening; the falling off of the nut body 1 is effectively prevented; the mounting nut can be easily disassembled, and the nut is fastened by locking the screw into the side face, so that the mounting nut is simple and easy to operate and high in reliability.

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 changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
