Abstract
The utility model discloses a kind of adjusting bolts, including screw rod, inner nut and outer nut, screw rod has positive external screw thread, inner nut has reversed external screw thread, the inner hole of inner nut is shiny surface, the inner hole front end of inner nut is provided with can be by the dynamic inserts with inner via hole for forming interior plus thread of screw drill, outer nut has and the matched reversed internal screw thread of reversed external screw thread, the tail end of outer nut has inwardly projecting bulge loop, the inner wall of bulge loop has interior plus thread, outer nut is mutually socketed and is threadedly coupled with inner nut, under use state, screw rod sinciput is on inserts and rotates, interior plus thread is formed in rotation process on inner via hole and inner nut is driven to rotate, and then rotate inner nut relative to outer nut, inner nut draws back along the tendency of reversed internal screw thread and clamps the first rack, provided by the utility model real by twisting screw rod forward Now to the adjusting bolt of the tension of two first racks.
Description
Technical field
The utility model relates to a kind of adjusting bolts.
Background technique
Tradition adjusts bolt and generally configures screw rod, inner nut and outer nut, but needs in adjusting nut respectively to spiral shell
Bar, inner nut and outer nut are adjusted.Its operation is relatively complicated, inconvenient for use to the more demanding of operator.
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 have positive external screw thread, and the inner nut has reversed external screw thread, and the inner hole of inner nut is shiny surface, the interior spiral shell
Female inner hole front end be provided with can by the dynamic inserts with inner via hole for forming interior plus thread of screw drill, the outer nut with
The tail end of the matched reversed internal screw thread of reversed external screw thread, the outer nut has inwardly projecting bulge loop, and the inner wall of bulge loop has
Interior plus thread, the outer nut is mutually socketed and is threadedly coupled with inner nut, and under use state, the screw rod sinciput is on inserts
And it rotates, form interior plus thread in rotation process on inner via hole and inner nut is driven to rotate, and then make the relatively outer spiral shell of inner nut
Mother's rotation, inner nut draws back along the tendency of reversed internal screw thread and clamps the first rack, when inner nut clamps the first rack
Screw rod, which continues to turn forward, to be made screw front end continue to be screwed into forward and passes through inserts, be formed in inside inserts screw rod it is matched it is interior just
Screw thread, the inner hole that final screw rod is then passed through the inner nut are threadedly coupled with the bulge loop of the outer nut, until screw rod 1 and interior spiral shell
Mother 2, which clamps, clamps the first rack and the second rack.
It is in the utility model the utility model has the advantages that adjusting bolt provided by the utility model in a state of use, before screw rod
It withstands on inserts and rotates, form interior plus thread in rotation process on inner via hole and inner nut is driven to rotate, and then make interior spiral shell
Parent phase rotates outer nut, and inner nut draws back along the tendency of reversed internal screw thread and clamps the first rack, when inner nut clamps
Screw rod, which continues to turn forward, when the first rack makes screw front end continue to be screwed into and pass through inserts, formation and screw rod inside inserts forward
Matched interior plus thread, the inner hole that final screw rod is then passed through the inner nut are threadedly coupled with the bulge loop of the outer nut, until
Screw rod and inner nut clamp the first rack.Its screw rod need to only keep continuing to be screwed into forward that the first rack and the second rack phase can be made
Mutually clamping, operation is more convenient, and it is lower to labor claim, be conducive to improve working efficiency.
Detailed description of the invention
Fig. 1 is the separate structure schematic diagram provided by the utility model for adjusting bolt.
Specific embodiment
The technical solution that according to the present invention will be described in detail below with reference to the accompanying drawings:
Adjusting bolt provided by the utility model, including screw rod 1, inner nut 2 and outer nut 3, screw rod 1 have just outside spiral shell
Line, the inner nut 2 have reversed external screw thread, and the inner hole of inner nut 2 is shiny surface, and the inner hole front end of the inner nut 2 is arranged
Having can be had and be matched with reversed external screw thread by the dynamic inserts 4 with inner via hole for forming interior plus thread of screw drill, the outer nut 3
Reversed internal screw thread, the tail end of the outer nut 3 has inwardly projecting bulge loop 5, and the inner wall of bulge loop 5 has interior plus thread, institute
It states outer nut 3 and is mutually socketed and is threadedly coupled with inner nut 2, under use state, 1 sinciput of screw rod is on inserts 4 and rotates,
Interior plus thread is formed in rotation process on inner via hole and inner nut 2 is driven to rotate, and then makes inner nut 2 with respect to 3 turns of outer nut
Dynamic, inner nut 2 draws back along the tendency of reversed internal screw thread and clamps the first rack 6, when inner nut 2 clamps the first rack 6
Screw rod 1, which continues to turn forward, makes 1 front end of screw rod continue to be screwed into and pass through inserts 4 forward, and inserts 4 is drilled be formed after moving using easy
The material of internal screw thread is constituted, and inserts 4 is plastic part in the present embodiment, is formed in the matched interior plus thread of screw rod 1 inside inserts 4,
The inner hole that final screw rod 1 is then passed through the inner nut 2 is threadedly coupled with the bulge loop 5 of the outer nut 3, until screw rod 1 and interior spiral shell
Mother 2 tenses the first rack 6 and the second rack 7.In the present embodiment, inserts rotates in order to prevent, before the internal screw thread inner hole
End has polygon slot 8, and the inserts is matched with 8 hole of polygon groove, and the inserts 4 is embedded in polygon slot 8, described more
Side shape slot 8 is hexagon.
