Abstract
The utility model discloses a hot -galvanize lock nut, including nut body and locking silk. A perforation is offered to the axial on the terminal surface of nut body, locking silk alternates back and this terminal surface of buckling in the perforation of nut body and on a terminal surface of nut body is laminated, and the firmly screw tooth top of nut body is supported to the end of locking silk. The utility model discloses a hot -galvanize lock nut can be well with bolt or screw rod fastening, have good locking ability, twist and accord with the national standard requirement with the moment of back -outing, can used repeatedly and do not become invalid.
Description
Technical field
The utility model relates to a kind of thread connector, particularly relates to a kind of hot galvanizing locking nut.
Background technique
When structure bears alternate load or have the occasion employing thread connector of vibrations, be necessary the locking problem considering link.The anti-loose structure of thread connector is generally made on the nut of assembly.The form of usual employing has: 1) adopt pairs of anti-loose nut; 2) on nut, inlay nylon, play damping locking; 3) combine with pad, play retaining effect; 4) execute must firm worm structure locking etc., various informative.
Having the occasion of atmospheric corrosion, bolt connection part often can be considered to adopt the zinc-plated process of surface heat.After the surface of bolt connection part adopts hot galvanizing process, there is zinc layers on surface, and nut just needs to take to expand silk process, so just can not adopt above-mentioned anti-loose structure.
Model utility content
The purpose of this utility model is to provide a kind of hot galvanizing locking nut, it can well with bolt or screw rod fastening, there is excellent anti-loose ability, to be screwed into and the moment of back-outing meets Standard, can reuse and not lose efficacy.
The technological scheme realizing above-mentioned purpose is: a kind of hot galvanizing locking nut, comprises nut body and anti-loose wire, and the end face of described nut body axially offers a perforation; Described anti-loose wire to be interted in the perforation of described nut body and on an end face of nut body after bending and this end face is fitted, and the termination of anti-loose wire props up the screw thread tooth top of nut body.
Above-mentioned hot galvanizing locking nut, wherein, the profile of described nut body is positive six prisms.
Above-mentioned hot galvanizing locking nut, wherein, described anti-loose wire adopts stainless steel to make.
The technological scheme of hot galvanizing locking nut of the present utility model, embeds an anti-loose wire in the wall thickness part of hexagon nut along axis, and after the end face of nut is turned back, props up externally threaded tooth top by anti-loose wire one, play the effect of locking.Anti-loose wire has good elasticity and wear resistance, can provide stable, reliable surface friction drag, is interference fit with bolt, effectively prevents the pine relatively of screw pair to turn; Make lock nut have excellent anti-loose ability, can reuse and not lose efficacy, and twist moment and meet GB GB/T3098.9 " fastening piece mechanical property effective torque shaped steel hexagonal locking nut ".

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 2 a, Fig. 2 b and Fig. 2 c, hot galvanizing locking nut of the present utility model, comprise nut body 1 and steel wire 2, wherein:
The profile of nut body 1 is positive six prisms, and the end face of this nut body 1 axially offers a perforation 10;
Anti-loose wire 2 adopts stainless steel to make, and this anti-loose wire 2 to be interted in the perforation 10 of nut body 1 and on an end face of nut body 1 after bending and this end face is fitted, and the termination of anti-loose wire 2 props up the screw thread tooth top 11 of nut body 2.
Penetrating after in the perforation of nut body 1 in anti-loose wire 2, by anti-loose wire 2 being fixed on nut body 1 at process for pressing, and pressing position 3 being located on the outer surface of the nut body 1 of the bending end face near anti-loose wire 2.
The locking principle of hot galvanizing locking nut of the present utility model is: when with Bolt Connection, and nut 1 can only be turned clockwise; And when nut 1 is rotated counterclockwise, anti-loose wire 2 can increase the frictional force of nut counterclockwise movement, reach the object stoping nut loosening.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, when not departing from spirit and scope of the present utility model, various conversion or modification can also be made, therefore all equivalent technological schemes also should belong to category of the present utility model, should be limited by each claim.
Claims (3)
1. a hot galvanizing locking nut, comprises nut body and anti-loose wire, it is characterized in that, the end face of described nut body axially offers a perforation; Described anti-loose wire to be interted in the perforation of described nut body and on an end face of nut body after bending and this end face is fitted, and the termination of anti-loose wire props up the screw thread tooth top of nut body.
