Abstract
The invention discloses a quick assembly and disassembly type nut. A right half threaded sleeve and a left half threaded sleeve which are formed by dichotomizing the same nut are installed in a middle tapered hole of a fixing sleeve through conical surfaces of outer circles of th right and the left half threaded sleeves; and concentric pressure is generated on the conical surfaces of the right half threaded sleeve and the left half threaded sleeve so as to achieve the purposes of self-locking and release. According to the invention, convenience for working places and equipment with the need of repeatedly assembling and disassembling nuts is provided; and the quick assembly and disassembly type nut is beneficial to improving working efficiency.
Description
Technical field
The present invention relates to a kind of nut, relate in particular to a kind of quickly dismantled nut, belong to machinery standard component technical field.
Background technique
Nut is a kind of component of machine that face is big, amount is wide that uses; In many occasions; Be used to connect fixing nut needs dismounting times without number, existing nut generally is whole structural type, can't reach the purpose of fast assembling-disassembling; The nut of this spline structure is unfavorable for improving the efficient of work in application places that need repeated disassembled and assembled.
Summary of the invention
The objective of the invention is to: can't realize fast assembling-disassembling to existing monolithic construction nut; Be unfavorable for the defective of increasing work efficiency; The present invention provides a kind of quickly dismantled nut; Make things convenient for operational site that some need the repeated disassembled and assembled nut and equipment need, be beneficial to reach the purpose of increasing work efficiency.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of quickly dismantled nut, it comprises: fixed cover, right partial thread cover, left partial thread cover, spline key, cover plate.It is characterized in that: described right partial thread cover forms with the otch that left partial thread cover is made subdivision by the nut of an integral body along the central cross-section position; Each right partial thread cover is processed conical surface with the outside of left partial thread cover; Overlap along being shaped on chute on the male cone (strobilus masculinus) of central axial direction with left partial thread at each right partial thread cover; The centre of described fixed cover has cone shape hole; The tapering of said cone shape hole is identical with the tapering of the outer circle conical surface of right partial thread cover and left partial thread cover; Dissecing in the cone shape hole that actinal surface relatively is installed in thread bush of right partial thread cover and left partial thread cover installs and fixes the spline key on thread bush, the inner head of said spline key is connected in the chute of right partial thread cover and left partial thread cover.
Working principle of the present invention is: the present invention in use, the suffered pretightening force of screw thread is along the vertex of a cone direction of circular cone, so; When double-screw bolt being installed in middle the interior threaded hole that right partial thread cover and left partial thread cover formed and since about the partial thread cover receive the pulling force that makes progress, so; Left and right sides partial thread cover just moves up, and simultaneously, compresses to opposite separately; And the degree of tightening Yu of screw thread is tight, and strength Yu who compresses mutually separately is strong, thereby double-screw bolt is locked; And when the time of loosening, its active force is just in time opposite, and disengages apace between the screw thread of fit in making.
Beneficial effect: can find out by work structuring of the present invention and working principle, the present invention can make things convenient for operational site that some need the repeated disassembled and assembled nut and equipment need, help increasing work efficiency.
