Description
Technical field
The utility model is related to a kind of adjusting bolts.
Background technology
Traditional adjusting bolt generally configures screw rod, inner nut and outer nut, but is needed respectively to spiral shell in adjusting nut
Bar, inner nut and outer nut are adjusted.Its operation is relatively complicated, inconvenient for use to the more demanding of operating personnel.
Utility model content
In view of the shortcomings of the background art, the technical problem to be solved by the utility model is to provide one kind only pass through to
Preceding stubborn screw rod realizes the adjusting bolt of the tension to two first racks.
The utility model adopts the following technical scheme that complete：Adjusting bolt, including screw rod, inner nut and outer spiral shell
Mother, screw rod carry positive external screw thread, and the inner nut carries reversed external screw thread, and the endoporus front of inner nut carries the first internal thread
Section, the first internal thread segment carry positive internal thread, and the endoporus rear portion of inner nut carries screens portion, the outer nut carry with it is reversed
The matched second reversed internal thread of external screw thread, the outer nut are mutually socketed and are threadedly coupled with inner nut, the screw rod and institute
The endoporus front for stating inner nut forms threaded connection, and the end of the screw rod is with the matched card in screens portion with inner nut endoporus
Position end, the screens end can drive inner nut to rotate after being caught in the screens portion；Under use state, the screw rod is rotated into institute
It states the first internal thread segment in the endoporus of inner nut and along endoporus front to advance, when the screens end of screw rod reaches the inner nut
When screens portion, screens end, which is squeezed into screens portion, promotes screw rod to drive entire inner nut, and then inner nut is made to be rotated relative to outer nut,
Inner nut draws back along the tendency of the second internal thread and clamps the first rack, and when inner nut clamps the first rack, screw rod continues
The screens portion for making screw rod screens end overcome inner nut is turned forward, and then screw rod is promoted to continue on the first internal thread of inner nut
The opposite inner nut of section is persistently tightened until screw rod and inner nut clamp the first rack.
Advantageous effect in the utility model：Adjusting bolt provided by the utility model is screwed into forward inner nut in screw rod
Afterwards, can by the screens end of screw front end drive inner nut screens portion, make inner nut with respect to outer nut along left-hand thread backward
It moves back and reaches at the first rack, screw rod screens end overcomes the clamping in screens portion to back-out interior spiral shell forward after the first rack is clamped
Mother, inner nut are no longer secured to screw rod end, and the first rack can be clamped when screw rod continues to turn forward at this time.It is new using this practicality
The adjusting bolt of type can be screwed into the effect that the fastening to the first rack and tension can be realized by lasting forward direction, and operation is more
It is convenient, it is lower to the skill requirement of worker, it can realize sharp work.
