Description

Nut

Technical Field

The utility model belongs to the technical field of the nut, specifically be a nut.

Background

An interlockable spring clamp locknut is provided according to publication No. CN114688135A, which discloses in the specification: when the work piece vibrates under the vibration load effect, the lock nut can be at first not hard up, nevertheless because the horizontal ring groove of collet chuck is to the constraint effect of the bulge loop of lock nut, prevents that the lock nut is not hard up, and the lock nut retrains again that the clamp nut is not hard up, has just so realized the function of interlocking, but its still has following defect:

although the nut can be prevented from loosening in the nut mounting process, the whole structure is complex, the machining process is complex, and therefore the production cost is high.

SUMMERY OF THE UTILITY MODEL

To the above situation, for overcoming prior art's defect, the utility model provides a nut, effectual one kind can prevent not hard up, and low in production cost's nut that provides.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a nut, includes the nut body, seted up the screw in the nut body, still set up flutedly in the nut body, be provided with elastic component and clamping ring in the recess, the clamping ring is located the top of elastic component, and the clamping ring part stretches out the recess.

Preferably, the elastic member is a rubber ring, and the shape of the rubber ring is annular.

Preferably, a tapered groove is formed at one end of the pressing ring close to the elastic piece, and the pressing ring is annular.

Preferably, the compression ring is connected with a limiting ring, a limiting groove is formed in the groove, and the limiting ring and the limiting groove are arranged in a sliding mode.

Preferably, the end face of the nut body is provided with a plurality of bulges which are uniformly distributed.

Compared with the prior art, the beneficial effects of the utility model are that:

in operation, through the clamping ring that sets up, the cooperation of elastic component and recess etc. is used, can play good locking effect when the nut installation, simultaneously because its structure is comparatively simple, consequently processing technology is comparatively simple, and it utilizes current part can realize the assembly, consequently low in production cost.

in the figure: 1. a nut body; 2. a screw hole; 3. a groove; 4. an elastic member; 5. pressing a ring; 6. a tapered groove; 7. a limiting groove; 8. a limiting ring; 9. and (4) protruding.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the 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 efforts all belong to the protection scope of the present invention.

In the first embodiment, as shown in fig. 1-3, the utility model relates to a nut, which comprises a nut body 1, wherein a screw hole 2 is arranged in the nut body 1, and the nut body 1 can be connected with an external screw in a threaded manner;

a groove 3 is further formed in the nut body 1, an elastic piece 4 and a pressing ring 5 are arranged in the groove 3, the pressing ring 5 is located above the elastic piece 4, and part of the pressing ring 5 extends out of the groove 3; when screwing nut body 1 and making its and screwed connection, receive the extrusion back of contact surface when clamping ring 5, clamping ring 5 produces the extrusion to elastic component 4, elastic component 4 receives extrusion back self and takes place deformation, because its outside is blocked by fluted 3, the mode motion that is close to the screw behind the elastic component 4 deformation consequently, thereby extrude the screw, along with the twisting of screw moves, its extrusion dynamics is big more, consequently can provide great pretightning force, avoid the screw to take place not hard up phenomenon after the installation.

Specifically, the elastic member 4 is made of an elastic material, such as: rubber rings or gaskets, etc.

Furthermore, a conical groove 6 is formed at one end of the pressing ring 5 close to the elastic piece 4, and the pressing ring 5 is annular; when clamping ring 5 and rubber circle contact, pressure can be exerted to the rubber circle from the flank to conical groove 6, compares in the pressure of exerting to the rubber circle from the top, and its extrusion dynamics is bigger to it is bigger to make the pretightning force, and locking effect is better.

In the second embodiment, different from the first embodiment, the pressing ring 5 is connected with the limiting ring 8, the limiting groove 7 is formed in the groove 3, and the limiting ring 8 and the limiting groove 7 are arranged in a sliding manner, so that the pressing ring 5 can be prevented from being separated from the nut body 1, and the nut body can be used after being taken out without being assembled; the terminal surface department of nut body 1 is provided with arch 9, and arch 9 has a plurality of and evenly distributed, can produce the extrusion to the contact surface through arch 9 to further improve nut body 1's locking effect.
