Description

A kind of checknut pressing ring

Technical field

The present invention relates to a kind of threaded ring, especially a kind of slim checknut pressing ring.

Background technique

In industrial circle, threaded ring using very universal, there is externally threaded threaded ring and threaded hole to cooperate, tool Internal thread threaded ring and bolt cooperation play fastening effect, due to be threaded in it is high-intensitive use and vibrate take place frequently Occasion can lead to the problem of loosening, influence the use of product, functions of the equipments is caused to fail.In order to guarantee making reliably and with long-term for product With, it is necessary to being threadedly coupled, progress is locking.The locking measures volume of current existing some threaded rings is all bigger, for one The occasion of a little installation threaded ring narrow spaces, existing threaded ring and locking measures are simultaneously not suitable for.

Summary of the invention

Present invention aims at a kind of slim checknut pressing ring is proposed, existing screw thread pressure in a limited space is solved Enclose the not applicable problem of locking measures.

Checknut pressing ring of the present invention, including ring shaped thread pressing ring and lock-screw, the ring shaped thread pressing ring The notch of connection threaded ring inner wall and outer wall is provided in annular wall, in the annular wall of the threaded ring above the notch It is provided with through-hole, the through-hole opposite position is provided with fixation in the annular wall of the threaded ring of the suitable order Hole, the lock-screw pass through the through-hole and are locked with the fixation hole.

Further, the ring shaped thread pressing ring is slim ring shaped thread pressing ring, the bottom of the slim ring shaped thread pressing ring Face is to top surface with a thickness of 2~4mm.

Further, the notch is the notch parallel with horizontal plane.

Further, the arc length of the notch is greater than the semicircle arc length of the annular wall of ring shaped thread pressing ring.

Further, the top surface of the threaded ring is provided with the handle hole for fastening thread pressing ring.

Further, the handle hole is symmetrically arranged multiple handle holes.

Further, the through-hole and the fixation hole are the through-hole of vertical direction.

Further, the fixation hole is threaded hole.

Further, the internal diameter of the ring shaped thread pressing ring is 5~40mm, outer diameter is 10~45mm.

Further, the ring shaped thread pressing ring is cyclic annular internal screw thread pressing ring or cyclic annular external screw thread pressing ring.

Using possessed by technical solution of the present invention the utility model has the advantages that

Checknut pressing ring of the present invention will have fixation hole side inside at the horizontal cut of threaded ring first, The place of being threadedly engaged of equipment is installed in place, and lock-screw, which is then passed through threaded ring, the logical of horizontal cut side middle position Hole is installed in the fixation hole of threaded ring, and tightens lock-screw, completes the installation of checknut pressing ring.Due to screw thread pressure There is horizontal cut at circle installation locking screw, under the action of lock-screw, two layers of place of being threadedly engaged of threaded ring is compressed, Hold matched thread tightly, meanwhile, compressed two layers of threaded ring has outside distracted reaction force, and to lock Tight screw plays anti-loose effect.Threaded ring and lock-screw mutually restrain locking, have reached good anti-loosing effect.This hair Bright slim checknut pressing ring has size ultra-thin, simple and reliable, low in cost, easy to use to wait many advantages.

Specific embodiment

Technical solution of the present invention is clearly and completely described below, it is clear that described embodiment is the present invention A part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not having Every other embodiment obtained under the premise of creative work is made, shall fall within the protection scope of the present invention.

In present embodiment, the checknut pressing ring, as depicted in figs. 1 and 2, including ring shaped thread pressing ring 1 and locking Screw 2 is provided with the notch 4 of connection threaded ring inner wall and outer wall in the annular wall of the ring shaped thread pressing ring 1, cuts described Mouthful top threaded ring annular wall on be provided with through-hole 5, in the annular wall of the threaded ring of the suitable order with institute It states 5 opposite position of through-hole and is provided with fixation hole 6, the lock-screw 2 passes through the through-hole 5 and the fixation hole 6 locking is solid It is fixed；Wherein, the lock-screw 2 is standard screws.

Further, in conjunction with above-mentioned technical proposal, in present embodiment, the ring shaped thread pressing ring is slim ring shaped thread Pressing ring, under the premise of the slim ring shaped thread pressing ring refers to that thread is same specification, the thickness phase of the ring shaped thread pressing ring To smaller, in present embodiment, the thickness of bottom surface to the top surface of the slim ring shaped thread pressing ring is preferably 2~4mm；Further Ground, in present embodiment, the internal diameter of the ring shaped thread pressing ring is 5~40mm, outer diameter is 10~45mm.

Further, in conjunction with above-mentioned technical proposal, in present embodiment, the notch 4 is parallel with horizontal plane cuts Mouthful.

Further, in conjunction with above-mentioned technical proposal, in present embodiment, the arc length of the notch 4 is greater than ring shaped thread pressure The semicircle arc length of the annular wall of circle.

Further, in conjunction with above-mentioned technical proposal, in present embodiment, the top surface of the threaded ring 1, which is provided with, to be used for The handle hole 7 of fastening thread pressing ring；Preferably, the handle hole 7 is symmetrically arranged multiple handle holes, present embodiment In, as shown in Figure 1, the handle hole 7 is symmetrically arranged two handle holes.

Further, in conjunction with above-mentioned technical proposal, in present embodiment, the through-hole 5 and the fixation hole 6 are vertical The through-hole in direction；Preferably, the fixation hole 6 is threaded hole.

Further, in conjunction with above-mentioned technical proposal, in present embodiment, the ring shaped thread pressing ring is cyclic annular internal screw thread pressure Circle or cyclic annular external screw thread pressing ring.

Checknut pressing ring of the present invention will have fixation hole side inside, especially at the horizontal cut of threaded ring first It is fixation hole be threaded hole when, will have threaded hole side inside at the horizontal cut of threaded ring, in being threadedly engaged for equipment Place is installed in place, and lock-screw is then passed through the through-hole that threaded ring has horizontal cut side middle position, is installed to screw thread In the fixation hole of pressing ring, and lock-screw is tightened, completes the installation of checknut pressing ring.Due to threaded ring installation locking screw There is horizontal cut at place, and under the action of lock-screw, two layers of place of being threadedly engaged of threaded ring is compressed, and has held tightly matched Thread, meanwhile, compressed two layers of threaded ring has outside distracted reaction force, and plays to lock-screw anti- Pine effect.Threaded ring and lock-screw mutually restrain locking, have reached good anti-loosing effect.Slim locking spiral shell of the invention Line pressing ring has size ultra-thin, simple and reliable, low in cost, easy to use to wait many advantages.
