Abstract
The utility model provides a sleeve hexagonal spanner, includes the sleeve of head, sets up porosely on the sleeve wall, the hole site is less than the hole diameter of sleeve outer wall department in the opening of sleeve inner wall end, the hole set up the edge at the hexagon, at the downthehole steel ball that is provided with, hole diameter that the diameter of steel ball is less than sleeve outer wall department is greater than hole site in the opening of sleeve inner wall end, sets up an inclined plane in the steel ball outside along sleeve axial displacement, the inclined plane along cover cylinder diameter to the restraint on the spanner, the elastic compression device of direction about being provided with on the inclined plane, when natural state, elastic compression device pushes down the inclined plane makes the bottom on inclined plane be located under the sleeve bottom surface. This spanner can effectually avoid its bight to become the life of the emergence of slick and sly phenomenon, effectual extension standard component and instrument.
Description
Technical field
This utility model relates to a kind of spanner, particularly to a kind of sleeve die nut, belongs to hardware & tools technical field.
Background technology
nullSleeve die nut uses in maintaining equipments widely，The hexagon inner chamber that existing sleeve die nut in use uses matches with hexagon bolt or nut and realizes rotary operation，This cooperation stress point in use is all in corner，This corner making hex bolts internal after a number of uses is slided by rounding，Cause, when using the work of hexagon socket head cap screw spanner, skidding occurs，Also existing sleeve die nut is caused the most also to there will be the phenomenon that angular position is slided by rounding，This causes in corner entirely just because of in use sleeve die nut and bolt strained position，And in ongoing operations is safeguarded，Such as in the plant maintenance of power plant，Due to equipment work under bad environment，In maintenance, often occur that hexagon socket head cap screw corrosion or other reason cause dismantling to get off，This also be that force part is all relevant in corner in sleeve die nut operation，In real work is applied，Need the most excellent a kind of sleeve die nut.
Summary of the invention
The purpose of this utility model is to overcome prior art middle sleeve die nut drawbacks described above in use, it is provided that a kind of sleeve die nut.
nullFor realizing the purpose of this utility model，Have employed following technical scheme: a kind of sleeve die nut，Sleeve including head，Sleeve wall is offered porose，Hole is positioned at the opening of sleeve lining end less than the bore dia at sleeve outer wall，Described hole is opened on hexagonal limit，Steel ball it is provided with in hole，The diameter of steel ball is positioned at the opening of sleeve lining end less than the bore dia at sleeve outer wall more than hole，Move axially along sleeve outside steel ball and an inclined-plane is set，Inclined-plane along sleeve radial constraint on spanner，The elastic pressuring clamping device of above-below direction it is provided with on inclined-plane，When naturalness，Elastic pressuring clamping device presses down inclined-plane to make the bottom on inclined-plane be positioned under sleeve bottom surface，Further，Described hole is symmetrical arranged one or more pairs of along sleeve axis，It is provided with steel ball in each hole，The outside of steel ball is provided with overcoat，Overcoat inner chamber is conical cavity，The face contacted with steel ball is inclined-plane，Overcoat offers perforation in the middle of top，Overcoat is located on die nut bar by perforation，Portion is provided with holddown spring on the coat，Holddown spring is the elastic pressuring clamping device of inclined-plane above-below direction，Die nut bar is provided with spring retainer portion，When naturalness，Holddown spring presses down the bottom making overcoat to be positioned under sleeve bottom surface.
nullOf the present utility model actively have the beneficial effects that: this utility model uses said structure in use，When sleeve is sheathed on hex bolts or nut，First jacket bottom is withstood，When continuing to move to bolt direction，Overcoat can be headed on move to die nut bar direction，In overcoat moving process, the inclined-plane of its conical cavity heads on steel ball and radially moves in sleeve and protrude sleeve lining and hold out against on the limit of hex bolts or nut，When rotated except set barrel chamber corner and bolt coordinate stress in addition to，The position that steel ball presses closer also can produce bigger pressure，Multiple moment of torsion generation point is produced in rotary course，Fastening or demounting bolt can be relatively easy to，Corner to bolt/nut and sleeve is also a kind of protection simultaneously，Its corner can be effectively avoided to become round the generation of sliding phenomenon，Effective prolongation standard component and the service life of instrument.

Detailed description of the invention
In order to explain enforcement of the present utility model more fully, it is provided that embodiment of the present utility model.These embodiments are only to elaboration of the present utility model, are not intended to scope of the present utility model.
In conjunction with accompanying drawing explanation further details of to this utility model, accompanying drawing is respectively labeled as: 1: sleeve；2: hole；3: inclined-plane；4: steel ball；5: holddown spring；6: spring retainer portion；7: die nut bar；8: overcoat；9: conical cavity.nullAs shown in drawings，A kind of sleeve die nut，Sleeve 1 including head，Sleeve wall is offered porose，Figure shows along symmetrically arranged two holes of bushing core，2 holes showing side，Hole is positioned at the opening of sleeve lining end less than the bore dia at sleeve outer wall，First can offer a larger-diameter hole on sleeve outer wall，Close to during barrel bore in the hole becoming small diameter，Hole is opened on hexagonal limit，Steel ball 4 it is provided with in hole，The diameter of steel ball 4 is positioned at the opening of sleeve lining end less than the bore dia at sleeve outer wall more than hole，Move axially along sleeve outside steel ball and an inclined-plane is set，Inclined-plane along sleeve radial constraint on spanner，The elastic pressuring clamping device of above-below direction it is provided with on inclined-plane，When naturalness，Elastic pressuring clamping device presses down inclined-plane to make the bottom on inclined-plane be positioned under sleeve bottom surface，Described hole is symmetrical arranged one or more pairs of along sleeve axis，Figure shows a pair，It is provided with steel ball in each hole，The outside of steel ball is provided with overcoat 8，Overcoat 8 inner chamber is conical cavity，9 show conical cavity，Conical cavity makes the face contacted with steel ball be inclined-plane，3 show inclined-plane，Overcoat offers perforation in the middle of top，Overcoat 8 is located on die nut bar 7 by perforation，Overcoat 8 top is provided with holddown spring 5，Die nut bar is provided with spring retainer portion 6，When naturalness，5 times pressures of holddown spring make the bottom of overcoat 8 be positioned under sleeve bottom surface.This utility model, when making, is first offered hole in sleeve wall, is placed in hole by steel ball, outside then overcoat being set in sleeve, finally fixes spring retainer portion.
After describing embodiment of the present utility model in detail, one of ordinary skilled in the art is clearly understood that, various change and amendment can carried out under spirit without departing from above-mentioned claim, all any simple modification, equivalent variations and modifications above example made according to technical spirit of the present utility model, belong to the scope of technical solutions of the utility model, and this utility model is also not only restricted to the embodiment of example in description.
