Abstract
The utility model relates to a nut, in particular to a tightening theftproof nut with five prisms. The tightening theftproof nut with five prisms comprises a nut contracting sleeve and a compression nut arranged at the upper part of the nut contracting sleeve, wherein the nut contracting sleeve is provided with a hollow part; an inner cavity is formed inside the compression nut and provided with threads, a circle of convex edges positioned below the bottom surface and outside the inner cavity is arranged on the lower bottom surface of the compression nut, a hollow part is arranged inside the nut contracting sleeve, and a reversed table structure is arranged at the upper part of the nut contracting sleeve; and the tightening theftproof nut is characterized in that the exterior of the compression nut adopts a regular pentagonal prism shaped structure encircled by five vertical planes. The tightening theftproof nut has the advantages of better theftproof effect.
Description
Technical field
The utility model relates to nut, specifically relates to a kind of enclasping type anti-theft nut with pentagonal prism.
Background technique
In the prior art, the enclasping type anti-theft nut comprises that nut shrinks overcoat and nut shrinks the gland nut on overcoat top, and nut shrinks overcoat and has hollow parts; The inside of gland nut has inner chamber, and inner chamber has screw thread, bottom surface has also that the bottom surface is following, beyond the inner chamber week protruding stupefied, described nut shrinks overcoat inside and has hollow parts, top has the structure of falling from power; Such enclasping type anti-theft nut in use, the protruding stupefied structure of falling from power of shrinking overcoat through nut was shunk and can be played the antitheft effect of holding tightly a week of gland nut; Such gland nut outside is positive six prism structures that six facades surround, and uses general tool just can install, unload, and anti-theft effect is relatively poor.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned shortcoming, provides a kind of anti-theft effect better anti-theft nut---pentagonal prism enclasping type anti-theft nut.
The technical solution of the utility model is achieved in that pentagonal prism enclasping type anti-theft nut, comprises that nut shrinks overcoat and nut shrinks the gland nut on overcoat top, and nut shrinks overcoat and has hollow parts; The inside of gland nut has inner chamber, and inner chamber has screw thread, bottom surface has also that the bottom surface is following, beyond the inner chamber week protruding stupefied, described nut shrinks overcoat inside and has hollow parts, top has the structure of falling from power; It is characterized in that: the outside of described gland nut is the positive pentagonal prism shape structure that five facades surround.
The beneficial effects of the utility model are: it is stronger that such pentagonal prism enclasping type anti-theft nut has special tool requirement property, the better advantage of anti-theft effect.
