Abstract
A kind of check bolt, it includes bolt body, pull bar, and auxiliary nut, described bolt body is to make through hole at existing bolt-center axis position, and inner circle taper hole is made in bottom and uniform gap composition is outputed on interior conical bore, inner circle taper hole in bolt body bottom sets one to rise joint with inner circle taper hole taper identical, pull bar is arranged in the intermediate throughholes of bolt body, the lower end of pull bar and the joint that rises are connected as a single entity structure, the upper part of pull bar is formed with male thread portion and sets an auxiliary nut, the invention of this reality has the preferable effect of anti-loosing effect, it disclosure satisfy that some special requirements closed for anti-loosing effect requirement high field.
Description
Technical field
The present invention relates to a kind of release bolt, belong to standard component technical field.
Background technology
It is known that：The various components of machine being connected with, it is higher for some requirements, especially require mutually to interconnect
The situation for occurring loosening is impermissible between the parts connect, must be requested that bolt has corresponding locking functions, existing locking
Although bolt structure is not quite similar, it is most of to there is the dissatisfactory defect of anti-loosing effect.
The content of the invention
It is an object of the invention to：There is provided a kind of anti-loosing effect preferable bolt, meet some for anti-loosing effect requirement
The special requirement that high field is closed.
A kind of check bolt of the present invention, it includes bolt body（1）, pull bar（2）And auxiliary nut（3）, institute
The bolt body stated（1）It is to make through hole (7) at existing bolt-center axis position, and makes in bottom inner circle taper hole
（6）And in interior conical bore（6）On output uniform gap（5）Composition, in bolt body（1）The inner circle taper hole of bottom（6）Set
One and inner circle taper hole（6）Taper identical rises joint（4）, pull bar（2）It is arranged on bolt body（1）Intermediate throughholes (7) in,
Pull bar（2）Lower end and rise joint（4）Be connected as a single entity structure, pull bar（2）Upper part be formed with external screw thread, in pull bar（2）'s
Male thread portion sets an auxiliary nut（3）.
Beneficial effect：The present invention locking principle be：Bolt body（1）After the parts connection being connected, auxiliary is tightened
Nut（3）, then pull bar（2）Tension is risen joint（4）, rise joint（4）There to be gap（5）Bolt body（1）Partly to four
All spreadings, so that locking purpose is reached,, can be by auxiliary nut after bolt fastening in order to reach more preferable anti-loosing effect
（3）, pull bar（2）And bolt body（1）It is welded as a whole, only need to be by pad Partial Resection during fractionation, it is possible to convenient
Split.By the present invention locking principle it can be seen from the present invention have the preferable effect of anti-loosing effect, disclosure satisfy that some for
Anti-loosing effect requires the special requirement that high field is closed.

Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, embodiment of the invention is：
A kind of check bolt, it includes bolt body（1）, pull bar（2）And auxiliary nut（3）, described bolt body（1）
It is to make through hole (7) at existing bolt-center axis position, and makes in bottom inner circle taper hole（6）And in interior conical bore
（6）On output uniform gap（5）Composition, in bolt body（1）The inner circle taper hole of bottom（6）One and inner circle taper hole are set
（6）Taper identical rises joint（4）, pull bar（2）It is arranged on bolt body（1）Intermediate throughholes (7) in, pull bar（2）Lower end
With the joint that rises（4）Be connected as a single entity structure, pull bar（2）Upper part be formed with external screw thread, in pull bar（2）Male thread portion set
One auxiliary nut（3）,, can be by auxiliary nut after bolt fastening in order to reach more preferable anti-loosing effect（3）, pull bar（2）With
And bolt body（1）It is welded as a whole, only need to be by pad Partial Resection during fractionation, it is possible to convenient to split.
