Abstract

The utility model discloses a combination lock nut, its characterized in that: the novel hexagonal socket nut is characterized by comprising an outer hexagonal nut and a thin outer hexagonal nut, wherein a first internal threaded hole is formed in the center of the outer hexagonal nut, a circumferential notch is formed in the hole wall of the first internal threaded hole, the circumferential notch penetrates through the whole height of the outer hexagonal nut, a second internal threaded hole is formed in the center of the thin outer hexagonal nut, and the second internal threaded hole and the first internal threaded hole have the same pitch. The utility model discloses both can carry out the nut and be connected with the fast-assembling that corresponds the bolt, realize locking function simultaneously again.

Description

Combined lock nut
Technical Field
The utility model relates to a fastener product, concretely relates to combination lock nut.
Background
Outer hexagon nut is very common in the fastener product, and outer hexagon nut is when using, and the internal thread hole of nut need begin to twist from the one end of bolt until the nut is screwed up, and whole twisting process needs the cost more time, and assembly efficiency is low, in addition, will realize outer hexagon nut's locking, still need to carry out and tighten with another nut usually.
Disclosure of Invention
In view of the problems existing in the prior art, the technical problem to be solved in the present invention is to provide a combined lock nut which can be used for both the quick assembly of a nut and a corresponding bolt and the locking and anti-loosening function.
The utility model discloses a through following technical scheme implementation:
combination lock nut, its characterized in that: the novel hexagonal socket nut is characterized by comprising an outer hexagonal nut and a thin outer hexagonal nut, wherein a first internal threaded hole is formed in the center of the outer hexagonal nut, a circumferential notch is formed in the hole wall of the first internal threaded hole, the circumferential notch penetrates through the whole height of the outer hexagonal nut, a second internal threaded hole is formed in the center of the thin outer hexagonal nut, and the second internal threaded hole and the first internal threaded hole have the same pitch.
The circumferential notches are symmetrically distributed along the circumference of the hole wall of the first internal threaded hole, and the circumferential angles of the two circumferential notches are larger than 90 degrees.
According to the technical scheme, when the bolt is in threaded connection with the corresponding bolt (the outer thread of the bolt is provided with the circumferential notch which is the same as the first inner thread hole), the first inner thread hole of the outer hexagon nut is firstly linearly sleeved into the outer circle of the bolt until the lower end face of the outer hexagon nut is contacted with the fastening end face, then the thin outer hexagon nut is preliminarily screwed, the outer hexagon nut is screwed for 90 degrees, the outer hexagon nut is screwed between the outer hexagon nut and the bolt, and then the thin outer hexagon nut is screwed, so that the locking and anti-loosening effects are achieved. The time of the whole threaded connection can be greatly shortened, so that the quick-assembly connection of the nut and the bolt is realized, and the locking and anti-loosening functions are realized at the same time.
Drawings
The utility model discloses there is following figure:
figure 1 is the outline structure diagram of the utility model,
figure 2 is a view in the direction of the end face of the outer hexagon nut of figure 1,
fig. 3 is an end view of the thin outer hexagonal nut of fig. 1.
Detailed Description
The details and the working principle of the embodiments of the present invention are described in detail below with reference to the accompanying drawings:
as shown in the figure, the utility model discloses a combination lock nut comprises outer hexagon nut 1 that thickness is thick and slim outer hexagon nut 2, the center of outer hexagon nut 1 is equipped with first internal thread hole 11, be equipped with circumference breach 12 on the pore wall of first internal thread hole 11, circumference breach 12 lays the two places of symmetry along the pore wall circumference of first internal thread hole 11, the circumferential angle of two places circumference breach 12 all is greater than 90 degrees, it is just right that there is 92 degrees generally, circumference breach 12 runs through outer hexagon nut 1's whole height, the center of slim outer hexagon nut 2 is equipped with second internal thread hole 21, second internal thread hole 21 has the same pitch with first internal thread hole 11.

Claims (2)
