Abstract
An anti-theft nut with internal threads comprises a nut body, an internal screw cap and a screw pedestal ring, and is characterized in that an upper side round hole and a lower side round hole are respectively formed at the upper end of the opening of the nut body, an inner chamber is formed in the nut body, an inner frame is arranged on the inner side of the opening of the nut body, main internal threads are formed at the rear end of the inner frame, the internal screw cap is arranged in the nut body, and the screw pedestal ring is mounted at the opening of the nut body; an upper groove and a lower groove are respectively formed on the outer side of the internal screw cap, and screw cap internal threads are formed in the internal screw cap; external threads are formed on the outer side of the screw pedestal ring; and the nut body, the internal screw cap and the screw pedestal ring can be disassembled. Since the internal screw cap can rotate in the inner chamber of the nut, the screw rod connected therewith can not be screwed down through common tools. The anti-theft nut with internal threads with reasonable structural design is endowed with certain safety anti-theft function and good sealing performance, and is particularly applied to important component fastening devices.
Description
Technical field
The utility model relates to a kind of antitheft internal threaded nut, relates to a kind of nut antitheft, anticorrosion, dustproof effect that has specifically, belongs to the hardware fitting field.
Background technique
Nut is one of frequent hardware fitting that use or that connect other parts on the mechanical part, and nut is to be screwed together by the screw rod of its inboard screw thread with equal specification, mainly plays the fastening effect to mechanical part.Existing nut exists that following some is not enough: one, nut and screw rod inlay screw after, screw rod is shaken easily in nut, it is not firm to cause component of machine to fix; Two, nut structure is too simple, when needs are laid down screw rod, only need general tool (as spanner, screw-driver etc.) just screw rod can be unclamped, in the time need on some security requirement high product, using to connected element, this conventional nut does not have any antitheft effect, and the thief is easy to just its component of fixing to be laid down steal.
The model utility content
The purpose of this utility model is to use the problem that exists at above-mentioned nut, has invented a kind of nut with antitheft effect.Be provided with an interior nut in the inner chamber of this nut, the screw socket place of nut is provided with the screw socket seal, with screw rod inlay be screwed on the nut after because interior nut can rotate in nut intracavity, so use general purpose tool to screw out and twist with being attached thereto the screw rod that connects.This nut structure is reasonable in design, has certain safe antitheft effect, and good seal performance especially is fit to use on important component fastening apparatus.
In order to achieve the above object, the utility model is realized by following technological means.
A kind of antitheft internal threaded nut, it is made up of nut main body, interior nut, screw socket seal three parts, it is characterized in that: be respectively arranged with mother rib lateral rotundum and following mother rib lateral rotundum in the open upper end of nut main body, be provided with inner chamber in the nut main body, the opening inboard of nut main body is provided with inside casing, the rear end of inside casing is provided with the main body internal thread, is provided with interior nut in nut main body, at the opening of nut main body the screw socket seal is installed.
The outside of nut is respectively arranged with upper groove and low groove in described, is provided with the nut internal thread in interior nut.
The arranged outside of described screw socket seal has outside thread (be used to inlay be screwed in main body internal thread).
Can dismantle between described nut main body and interior nut, the screw socket seal.
Using method: the inside casing place that earlier interior nut is installed to nut main body before using, and then the screw socket seal is installed to the opening of nut main body, carry out in will be when fastening screw rod precession nut main body, special tool (spline spoon bar) is inserted in the groove of the circular hole in the nut main body outside and the interior nut that its inside is provided with, this moment spline spoon bar play fixing in nut do not allow the effect of its rotation, at this moment can be in the screw rod precession nut main body, after withdrawing from special tool spline spoon bar, screw rod just can't screw out in nut main body; When owner need screw out screw rod in nut main body, only special tool spline spoon bar need be inserted in the groove of interior nut of the circular hole in the nut main body outside and its inside, and then rotary screw, interior nut is owing to blocked by spline spoon bar, can not follow screw rod with changeing, like this, screw rod can be screwed in the nut main body and withdraw from.
The utility model mainly has following beneficial effect:
Because interior nut can rotate in nut intracavity, so use general purpose tool to twist with being attached thereto the screw rod back-out that connects; This nut structure is reasonable in design, has certain safe antitheft effect, and good seal performance especially is fit to use on important component fastening apparatus.
