Abstract
The utility model discloses a heat treatment hardened screw anti-theft sheath with micro-tapered outer opposite angles, which comprises a heat treatment hardened screw anti-theft sheath body with outer opposite angles, a sheath bottom of the heat treatment hardened screw anti-theft sheath, a sheath top of the heat treatment hardened screw anti-theft sheath, inner wall micro-tapered opposite surfaces of the heat treatment screw anti-theft sheath body, inner wall micro-tapered opposite angles of the heat treatment screw anti-theft sheath body, an outer wall micro-tapered wall of the heat treatment screw anti-theft sheath body and an outer circumference wall of the heat treatment screw anti-theft sheath body. The sheath top of the heat treatment screw anti-theft sheath is provided with a topless straight sheath. The inner wall micro-tapered opposite surfaces of the heat treatment screw anti-theft sheath body are symmetrical tapered opposite surfaces. The inner wall micro-tapered opposite angles of the heat treatment screw anti-theft sheath body are symmetrical tapered opposite angles. The outer wall micro-tapered wall of the heat treatment screw anti-theft sheath body is a tapered wall. The outer circumference wall of the heat treatment screw anti-theft sheath body is a circumferential wall. After the utility model is matched and assembled with screws or screw nuts, the utility model can be used for theft prevention, fastening and installation for outdoor facilities which are easily stolen.
Description
One, affiliated technical field
The utility model is a kind of relating to carry out the equipped fastening piece accessory of antitheft reinforcing to being fixedly installed in outdoor equipment or its parts.
Two, background technique
To ending at present, existing outdoor power transformer, environmental protection facility and the decoration building object of much being installed on is stolen, and it has caused harm and destruction in various degree to society and people.
Though have fastening pieces such as non-standard screw in a small amount to carry out alternative use before this,, promptly still do not miss according to the robber as long as imitated non-standard component such as adorn, tears open at manual tool.
Three, summary of the invention
At being fixedly installed in outdoor many power transformers, environmental protection facility and the decoration building present situation that object is stolen and prior art is not enough at present, provide a kind of being easy to install, adorn the back firmly, 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 the outer diagonal angle of hard tapered external angle screw anti-theft cover, comprise that heat treatment increases the outer diagonal angle of hard tapered external angle screw anti-theft cover body 1, at the bottom of the heat treatment screw anti-theft condom 2, heat treatment screw anti-theft condom top 3, heat treatment screw anti-theft cover body inwall tapered external angle opposite 4, heat treatment screw anti-theft cover body inwall tapered external angle diagonal angle 5, the external wall tapered external angle of heat treatment screw anti-theft condom wall 6 and the external peripheral wall 7 of heat treatment screw anti-theft condom, heat treatment screw anti-theft condom top 3 is not for there being the straight cover in top, heat treatment screw anti-theft cover body is interior to be symmetry properties tapering opposite to wall tapered external angle opposite 4, heat treatment screw anti-theft cover body inwall tapered external angle diagonal angle 5 is symmetry properties tapering diagonal angle, the external wall tapered external angle of heat treatment screw anti-theft condom wall 6 is a tapered wall, and the external peripheral wall 7 of heat treatment screw anti-theft condom is a peripheral wall.
Described heat treatment screw anti-theft cover body inwall tapered external angle opposite 4 taperings are consistent with the tapering on the outer anti-theft screw nut parent outer wall tapered external angle opposite, diagonal angle of tapered external angle.Described heat treatment screw anti-theft cover body inwall tapered external angle opposite 4 taperings are consistent with the tapering on the outer anti-theft screw screw top outer wall tapered external angle opposite, diagonal angle of tapered external angle.Described heat treatment screw anti-theft cover body inwall tapered external angle diagonal angle 5 angles are consistent with the angle at the outer anti-theft screw nut parent outer wall tapered external angle diagonal angle, diagonal angle of tapered external angle.Described heat treatment screw anti-theft cover body inwall tapered external angle diagonal angle 5 angles are consistent with the angle at the outer anti-theft screw screw top outer wall tapered external angle diagonal angle, diagonal angle of tapered external angle.It is identical with the stero shape of the outer diagonal angle of tapered external angle anti-theft screw nut parent outer wall that described heat treatment increases the outer diagonal angle of the hard tapered external angle interior empty shape of screw anti-theft cover body 1 inwall.Described heat treatment increases the outer diagonal angle of hard tapered external angle screw anti-theft and overlaps empty shape and tapered external angle in 1 inwall stero shape of diagonal angle anti-theft screw screw top outer wall is identical outward.
The utility model is to utilize heat treatment to increase tapered external angle and the exterior circumferential configuration on the diagonal angle screw anti-theft cover outer wall outside the hard tapered external angle, it can make all artificially all can't fall back its screw threads and increase the double anti-theft function that the utility model after hard does not advance with the hacksaw saw through Overheating Treatment of instrument by hand after fully fastening, thereby makes all fastened things all can reach permanent antitheft purpose.
When meeting original-pack equipment or its parts need change refitting the time, the utility model can only adopt electric power utensil, oxygen to cut through sand, mill, could remove after welding, cutting.
The beneficial effects of the utility model are: simple in structure, cheap, suit convenience, antitheft reliable, obvious social benefit.
