Abstract

The utility model discloses a rivet turning nut with locking performance, which comprises a nut body (1) with an internal thread structure; an inner race position of an upper end of the nut body (1) is provided with a rivet turning section (2); and the nut body (1) is provided with a locking forming hole (3) which is communicated with the inner wall of the nut body (1). The rivet turning nut withthe locking performance can be arranged on a substrate, and then a screw or a bolt is arranged in an internal thread hole of the nut body, so the screw or the bolt is avoided to directly contact the substrate to prolong the service life of the threads and improve the joint strength of the threads; and because of the locking forming hole, the shock resistant and loose preventing performance of thread connection is improved. The rivet turning nut has simple structure, easy manufacture and good using effect.

Description

Sigma compactness with lock can turn over Insert Nut

Technical field

The utility model relates to a kind of nut, and especially a kind of sigma compactness with lock can turn over Insert Nut.

Background technique

At present, screw or bolt normally directly are fixed on the matrix that needs mounting screw or bolt in use, and screw or bolt are directly contacted with matrix.When assembling, need on matrix, produce the internal thread corresponding with screw or bolt, and screw or bolt can damage the internal thread of matrix under the situation of often dismounting, internal thread on the matrix back occurs damaging and is difficult for repairing, matrix is brought very big influence, and be threaded and have antidetonation, poor performance such as anti-loose.

The model utility content:

The purpose of this utility model is: provide a kind of sigma compactness with lock can turn over Insert Nut, it can avoid screw or bolt directly to be connected with matrix, and has increased the antidetonation that is threaded, anti-loose performance, to overcome the deficiencies in the prior art.

The utility model is achieved in that sigma compactness with lock can turn over Insert Nut, comprise the nut body of being with female thread structure, what be provided with annular in the inner ring position of the upper end of nut body turns over the riveting section, and is provided with a locking molding port on nut body, and the locking molding port is communicated with the inwall of nut body.

Be provided with in the position, outer ring of the upper end of nut body and turn over the riveting tooth.

The locking molding port is in the position of nut body height below 1/2.

Owing to adopted technique scheme, compared with prior art, the utility model adopts a sigma compactness with lock can turn over Insert Nut, it can be installed on the matrix, again screw or bolt are installed in the interior threaded hole of nut body, so just avoided screw or bolt directly to contact, played prolongation screw thread working life, increased the effect of the join strength of screw thread with matrix; And, the antidetonation that is threaded, anti-loose performance have been increased owing to be provided with the locking molding port.The utility model is simple in structure, makes easily, and using effect is good.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is a use schematic representation of the present utility model.

Embodiment

Embodiment of the present utility model: the sigma compactness made from lock can turn over Insert Nut as shown in Figure 1, when making, make the nut body 1 of a band female thread structure earlier, that produces annular in the inner ring position of the upper end of nut body 1 turns over riveting section 2, produces in the position, outer ring of the upper end of nut body 1 and turns over riveting tooth 4; And be provided with a locking molding port 3 in 1/3 position of nut body 1 bottom, locking molding port 3 is communicated with the inwall of nut body 1.

In use, earlier nut body 1 usefulness frock is installed in the mounting hole of matrix 5, will turns over riveting section 2 and turn over the riveting shaping with riveting tool then, it is fixed on the matrix 5, to lock molding port 3 again and shrink, nut body 1 is locked in the mounting hole of matrix 5, obtain structure as shown in Figure 2 at last.Turn over riveting tooth 4 and can improve the join strength that turns between riveting section 2 and the matrix 5, increase connection stability; The position of locking molding port 3 helps improving locking intensity below nut body 1/2.

Claims

1. a sigma compactness with lock can turn over Insert Nut, comprise the nut body (1) of being with female thread structure, it is characterized in that: what be provided with annular in the inner ring position of the upper end of nut body (1) turns over riveting section (2), and on nut body (1), being provided with a locking molding port (3), locking molding port (3) is communicated with the inwall of nut body (1).

2. sigma compactness with lock according to claim 1 can turn over Insert Nut, it is characterized in that: be provided with in the position, outer ring of the upper end of nut body (1) and turn over riveting tooth (4).

3. sigma compactness with lock according to claim 1 can turn over Insert Nut, it is characterized in that: locking molding port (3) is in the position of nut body (1) height below 1/2.
