Abstract
The utility model discloses a heat treated hardened screw anti-theft sleeve with top hole micro-tapered inner opposite angles and a concave straight groove, which aims to provide the technology of the utility model having the advantages of simple structure and reliable theft prevention. The utility model comprises a screw anti-theft sleeve body (1), a sleeve bottom (2), a sleeve top (3), inner wall micro-tapered opposite angles (6) of the sleeve body, inner wall micro-tapered opposite surfaces (7) of the sleeve body, an outer wall micro-tapered wall (9) of the sleeve body and an outer circumference wall (10) of the sleeve body. A screw anti-theft sleeve top hole (4) and a screw anti-theft sleeve top hole wall (5) are arranged on the sleeve top (3). Concavo-convex interphase inner wall micro-tapered concave straight slots (8) of the screw anti-theft sleeve body are arranged on the inner wall micro-tapered opposite surfaces (7) of the sleeve body. Before the utility model is installed, the aim of permanent theft prevention can be achieved so long as conventional screws or screw nuts are completely and tightly fixed on relevant objects, and the utility model is sheathed and fastened on screw nail top outer walls or screw nut outer walls. The utility model can be widely suitable for theft prevention, reinforcement and installation for facilities or installations which are fixedly installed outdoors and easily stolen.
Description
Technical field
The utility model is a kind of relating to carry out the fastening piece accessory of antitheft reinforcing suit to being fixedly installed in outdoor easy pirate facility equipment, and more particularly, it is a kind of screw anti-theft cover.
Background technique
To ending at present, the existing objects such as outdoor electric power facility, environmental protection facility and decoration, building that much are fixedly installed in are stolen, and it has caused harm and destruction in various degree to society and people.Though have non-standard fastener screw in a small amount to carry out alternative use before this,, promptly still do not miss according to stealing as long as the dress of imitated this non-tender, tear instrument open.
Summary of the invention
The purpose of this utility model is for overcoming deficiency of the prior art, provide a kind of simple in structure, antitheft reliable the utility model technology.
The technological scheme that its technical problem that solves the utility model adopts is:
The utility model heat treatment increases has the recessed straight flute screw anti-theft of apical pore tapered external angle inner opposite angle cover to comprise screw anti-theft cover body 1, the cover end 2, cover top 3, body inwall tapered external angle diagonal angle 6, body inwall tapered external angle opposite 7, body outer wall tapered external angle wall 9 and body outer circle wall 10 firmly; On cover top 3, be provided with the screw anti-theft condom apical pore 4 and the screw anti-theft condom apical pore wall 5 of linking body structure; On body inwall tapered external angle opposite 7, be provided with the recessed straight flute 8 of screw anti-theft cover body inwall tapered external angle of concavo-convex alternate linking body structure.
Described screw anti-theft cover body 1 is hard workpiece for heat treatment increases; Described screw anti-theft condom apical pore 4 diameters are less than the interior empty diameter on body inwall tapered external angle opposite 7.
The beneficial effects of the utility model are:
1, the utility model is before suit, as long as conventional screw or nut are anchored on the related item fully, then the utility model suit, be anchored on the screw screw top outer wall or after on the nut parent outer wall, just can reach permanent antitheft purpose.The utility model can be widely used in the antitheft reinforcing that is fixedly installed in outdoor easy pirate facility or equipment is installed;
2, the utility model is simple in structure, and is simple for production, antitheft reliable, cheap, acts on hugely, and social benefit is obvious.
