Abstract
The utility model discloses a high -voltage direct -current relay's axle sleeve, the guiding hole that runs through about the axle sleeve is formed with, the guiding hole inner wall is smooth structure, is formed with the outside convex protruding muscle of a plurality of on the outer wall of axle sleeve, protruding flaccidity of tendon and muscle is to setting up and being parallel with the axis of axle sleeve. The utility model discloses a setting up the protruding muscle of certain thickness on the axle sleeve outer wall, impressing the axle sleeve in the clearing hole of yoke board, the deformation through protruding muscle makes the axle sleeve card in the clearing hole, can not cause the damage to the clearing hole of yoke board, makes the axle sleeve fixed more firmly, more convenient.
Description
Technical field
This utility model relates to the axle sleeve of a kind of HVDC relay.
Background technology
Set up on yoke plate in HVDC relay and be equipped with axle sleeve, guide for the catch bar being fixed on dynamic iron core is formed, and avoid catch bar to produce friction with yoke plate, but existing axle sleeve more difficulty fixing with yoke plate, yoke plate is caused damage by the fixing meeting of axle sleeve and yoke plate, axle sleeve week footpath cross the thick or meticulous assembling inconvenience that all can cause axle sleeve and yoke plate.
Summary of the invention
The purpose of this utility model is to provide one and is conveniently fixed with yoke plate, and the axle sleeve of the most firm fixing HVDC relay.
For achieving the above object, this utility model adopts the following technical scheme that the axle sleeve of a kind of HVDC relay, described axle sleeve is formed with the pilot hole run through up and down, described pilot hole inwall is smooth structure, being formed with several outwardly convex tendons on the outer wall of axle sleeve, longitudinally disposed and with axle sleeve the axis of described convex tendon is parallel.This utility model is by arranging certain thickness convex tendon on axle sleeve outer wall, axle sleeve is pressed into yoke plate by hole, make axle sleeve be stuck in by hole by the deformation of convex tendon, yoke plate will not be caused damage by hole, make fixing the most firm, more convenient of axle sleeve.
As preferably, described axle sleeve includes in the middle part of axle sleeve top, axle sleeve and axle sleeve bottom, and described convex tendon is arranged in the middle part of axle sleeve, and described axle sleeve bottom is the frustum structure that the big lower end diameter of upper end diameter is little.Above-mentioned setting is easy to be pressed into by hole axle sleeve.
As preferably, described convex tendon is distributed on the outer wall in the middle part of axle sleeve along the circumferential uniform intervals of axle sleeve.
As preferably, described convex tendon is at least three.
As preferably, described axle sleeve top is diametrically more than the loop configuration in the middle part of Upper shaft sleeve.
As preferably, described axle sleeve top is the frustum structure that the big lower end diameter of upper end diameter is little.Can the structure on chosen axis set top as required, axle sleeve top diametrically can avoid axle sleeve to depart from from yoke plate more than the loop configuration in the middle part of axle sleeve, the pyramidal structure that axle sleeve top is up-narrow and down-wide be easy to axle sleeve entrance yoke plate by hole.
As preferably, the cross section of described convex tendon is triangular in shape or square or isosceles trapezoid or sector.
This utility model is by arranging certain thickness convex tendon on axle sleeve outer wall, axle sleeve is pressed into yoke plate by hole, axle sleeve is made to be stuck in by hole by the deformation of convex tendon, the frustum structure of axle sleeve bottom is easy to staff by axle sleeve press-in by hole, and this utility model has fixes advantage more convenient, the most firm by axle sleeve and yoke plate.

Detailed description of the invention
The axle sleeve of a kind of HVDC relay of the present utility model, axle sleeve 3 fixes with yoke plate 1, yoke plate be formed with that the catch bar 2 being available on dynamic iron core 6 passes by hole, axle sleeve 3 is fixed on by hole.Axle sleeve 3 is formed with the pilot hole 5 run through up and down, pilot hole 5 inwall is that smooth structure is so that catch bar 2 contacts with the inner wall smooth of pilot hole 5, three outwardly convex tendons 4 it are formed with on the outer wall of axle sleeve 3, the cross section of convex tendon 4 is that sector is arranged, and convex tendon 4 is longitudinally disposed and parallel with the axis of axle sleeve 3.
Axle sleeve 3 includes in the middle part of axle sleeve top 11, axle sleeve 12 and axle sleeve bottom 13, convex tendon 4 is arranged in the middle part of axle sleeve on 12, three convex tendons 4 are distributed in the middle part of axle sleeve on the outer wall of 12 along the circumferential uniform intervals of axle sleeve, axle sleeve bottom 13 is the frustum structure that the big lower end diameter of upper end diameter is little, and axle sleeve top 11 is diametrically more than the loop configuration of 12 in the middle part of Upper shaft sleeve.
This utility model is by arranging certain thickness convex tendon 4 on axle sleeve 3 outer wall, axle sleeve 3 is pressed into by hole, axle sleeve 3 is made to be stuck in by hole by the deformation of convex tendon 4, damage will not be caused to by hole, and this utility model has axle sleeve and yoke plate are fixed advantage more convenient, the most firm.
