Abstract
The anti-theft capped screw nut consists of conic nut body with inner thread and at least three outer slots, semi-spherical top cap and bottom disc seat, with the three parts are connected integrally. The nut body and the seat have the same inner thread and the top cap is hollow. The anti-theft capped screw nut has reasonable structure, high fastening and anti-theft performance, and is convenient, reliable, antirust and long in service life.
Description
Invention field
What the present invention relates to is a kind of nut or nut structure that is used to be matched in fixing bolt, belongs to a kind of fastening piece class.
Background technique
The product that bolt of prior art (screw) and nut (nut) etc. use for complementing one another is exclusively used in two strong bonded between the object as fastening piece, fastening etc. as track.At present, fixing bolt that uses on track and nut are essentially conventional conventional construction, be that bolt is that cylindrical body (shaft-like) is provided with outside thread, and be provided with internal thread at the nut body endoporus of band hexagonal, this nut is referred to as hexagon nut again, and the two spins mutually to realize fastening purpose.Because China railways has nearly 100,000 kilometers, and mostly be unmanned greatly, because of being subjected to the influence of region, weather, various factors such as artificial, most of bolt and nut are serious or suffer artificial destruction and theft because of unattended gets rusty, and the fixedly connected of track is on the hazard.Under the situation that railway repeatedly raises speed,, fastening piece causes that very easily car turns over railway traffic accidents such as the people dies because lacking or suffer to destroy.Though the nut of more existing waterproof constructions occurs in recent years, they still can't satisfy the antitheft problem of fastening piece that present urgent need solves.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, and provide a kind of fastening performance good, and the antitheft cap nut that anti-theft capability is strong, it is made up of the block that the threaded nut body of inside fire attack links to each other with top, the profile of nut body is a cone shape, is shaped on three groovings on the cone at least.
At least be shaped on three uniform groovings on the described conical nut body, the bottom of nut body is connected with discoidal base, and base, nut body and block three join together, attacks identical internal thread on base and nut body.
Described block is semi-spherical shape, inner hollow.
The present invention compared with prior art, have rational in infrastructure, compactness, easy to use, reliable, can not only prevent that rainwater from invading, solve Yi Shengxiu, the problem that working life is short; And can also prevent that other people from utilizing the general utility tool theft and destroying fastening piece and rail facility, and make it have fastening performance good, anti-theft capability is strong, can prolong technique effects such as its working life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is that the A of Fig. 1 is to structural representation.
Embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: shown in the figure, the present invention mainly is made up of the block 2 that the threaded nut body 1 of inside fire attack links to each other with its top.Nut body 1 profile is a cone shape, and is to be similar to cylindrical cone shape, is shaped on three groovings 3 on cone, and these three groovings 3 are distributed on the conical nut body.Be provided with discoidal base 4 in the bottom of nut body, and base 4 nut bodies 1 and block 2 threes join together, and with the nut body inside fire attack identical internal thread is arranged at base.Described block 2 built in the top of nut body 1, is semi-spherical shape by weldering, and inner hollow can be placed the things such as butter of antirust usefulness in it.Three groovings 3 of the present invention can replace with not uniform three groovings 3 at least; Also available uniform odd number grooving replaces, as five groovings etc.Its purpose is that its people can't use instrument such as common wrench to pull nut body, makes itself and supporting bolt loosening mutually.Grooving 3 of the present invention can be parallel with the axle center, also can with axle center slightly inclined.Described coniform nut body also can be a cylindrical body, and they belong to equivalence and replace.The present invention can be widely used in railway, metallurgy, bridge, chemical industry, electric power, coal, cement, subway, departments such as forestry.
