Description
Technical field
The present invention relates to technical field of fastening, in particular to a kind of primary and secondary setscrew component.
Background technique
Existing setscrew, all equipped with expansion pipe sleeve, structure is complicated, and main screw cannot be used alone；For another example work
The mold used in industry is often dismounted, and the time has grown screw-socket and can loosen, therefore to the cooperation precision of screw and screw hole
On have very high requirement, the screw of common fixed specification is difficult to realize high-precision fastening effect；Common setscrew can not
It cannot be utilized again after adjusting elasticity degree and disassembly.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the present invention adopts the following technical scheme: a kind of primary and secondary expands
Screw assembly, including bolt, screw, the screw head are equipped with the inner hole that can cooperate manually or electrically tool spinning in and out, institute
Stating bolt includes bolt head, screw rod, and screw-in mouth is opened up in the middle part of the bolt head, and inside screw opens up band internal thread through-hole,
The screw rod is axially arranged with crack, is screwed into the change bolt of the relative position in the through-hole of inside screw to quilt by controlling screw
The tightness of securing objects.
Preferably, the screw is with externally threaded cylinder/or with externally threaded rotary table；
Preferably, the bolt head is hexagonal bolt head；
Preferably, the through-hole radial dimension of the inside screw is less than the radial dimension of the screw-in mouth in the middle part of bolt head；
Preferably, the radial dimension of the through-hole middle and upper part is greater than the radial dimension of through-hole lower part；
It is further preferred that the crack is four and is evenly distributed in screw rod circumferential direction.
Compared with prior art, beneficial effects of the present invention are as follows:
The configuration of the present invention is simple, external bolt can be used alone；The mold for another example industrially used often by
Dismounting, time have grown screw-socket and can loosen, therefore to there is very high requirement in the cooperation precision of screw and screw hole, the present invention is logical
It crosses the relative position that control screw is screwed into the through-hole of inside screw and changes bolt to by the tightness of securing objects；This hair
Bright disassembly is simple, can Reusability.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-6, a kind of primary and secondary setscrew component, including bolt 1, screw 2 are please referred to, the screw head, which is equipped with, to match
The inner hole 3 of manually or electrically tool spinning in and out is closed, the bolt 1 includes bolt head 4, screw rod 5, is opened in the middle part of the bolt head 4
If screwing in mouth 6, band internal thread through-hole 7 is opened up inside screw rod 5,5 axial direction of screw rod is equipped with crack 8, by controlling spiral shell
Nail 2 is screwed into the relative position in the through-hole 7 inside screw rod 5 and changes 1 pair of the bolt tightness by securing objects；The screw
2 is with externally threaded cylinders/or with externally threaded rotary table；The bolt head 4 is hexagonal bolt head；It is logical inside the screw rod 5
7 radial dimension of hole is less than the radial dimension of the screw-in mouth 6 at 4 middle part of bolt head；The radial dimension of 7 middle and upper part of through-hole is greater than logical
The radial dimension of 7 lower part of hole；The crack 8 is four and is evenly distributed in 5 circumferential direction of screw rod, the radial size of screw 2 and spiral shell
6 radial dimension of screw-in mouth on bolt head 4 is consistent.
Working principle: when being fastened to object, first bolt 1 manually or electrically is screwed in by the fastener of securing objects
In preformed hole, if bolt 1 of the invention, which is used only, can reach fastening effect, just it is without the use of screw 2 of the invention；If
Expected fastening effect cannot be reached using only bolt 1 of the invention, screw 2 of the present invention can manually or electrically be screwed in bolt
The screw-in mouth 6 at first 4 middle part, further screws in the through-hole 7 in screw rod 5, and through-hole is by the tension from screw 2, on screw rod 5
Four cracks 8 strut outward, and screw rod 5 is radial to become larger, and are screwed into the opposite position in the through-hole 7 inside screw rod 5 by controlling screw 2
It sets and changes 1 pair of the bolt tightness by securing objects.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
