Abstract
The utility model discloses a heat treatment hardened anti-theft screw with an external circumference tapered wall, which aims to provide the technology of the utility model having the advantages of simple structure, easy assembly and reliable theft prevention. The utility model comprises a screw nail body (1), a screw nail top (2), a screw nail rod (5) and a nail rod screw thread (6), wherein an outer wall external circumference (3) of the heat treatment anti-theft screw nail top and an external circumference tapered wall (4) of the heat treatment anti-theft screw nail top which are in a connecting body structure are respectively arranged on the outer wall of the screw nail top (2). The screw nail body (1) is a workpiece hardened by heat treatment. After the utility model is tightly fixed in screw holes of relevant facilities through a three-holding movable spanner, only a special tool can screw and unscrew the screw thread, therefore all objects need to be fastened can achieve the aim of permanent theft prevention. After the utility model is matched and used with the three-holding movable spanner, the utility model can be widely suitable for the theft prevention, reinforcement and installation for outdoor facilities which are easily stolen.
Description
Technical field
The utility model is a kind of relating to carry out the fastening piece accessory that antitheft reinforcing is installed to being installed on outdoor facility, and more particularly, it is a kind of anti-theft screw.
Background technique
To ending at present, owing to lack fastening pieces such as real effectively anti-theft screw, cause the objects such as electric power facility, environmental protection facility and decoration building that much are fixedly installed in outdoor easy robber location stolen, it has caused harm and destruction in various degree to society and people, though having in a small amount before this, the non-standard fastener screw has carried out alternative use, but it is, promptly still errorless according to stealing as long as the dress of imitated its non-standard component, tear manual tool open.
Summary of the invention
The purpose of this utility model is for overcoming deficiency of the prior art, providing a kind of simple in structure, and is equipped convenient, 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 hard excircle tapered wall anti-theft screw, comprises screw ailing body 1, screw screw top 2, screw ailing bar 5 and nail bar screw thread 6; On screw screw top 2 outer walls, be respectively equipped with the heat treatment anti-theft screw screw top outer wall excircle 3 and the heat treatment anti-theft screw screw top excircle tapered wall 4 of linking body structure; Screw ailing body 1 is hard workpiece for heat treatment increases.
The beneficial effects of the utility model are:
1, the utility model rely on its screw top outer wall the specific function structure and after Overheating Treatment increases hard processing, have only use to lean on adjustable spanner and could adorn, tear open the utility model as required for three of its supporting manufacturing, the utility model is except that with this special tool, all the other any manual tools all can not its screw thread of forward and back, thereby can make all fastened things all can reach permanent antitheft purpose; The utility model and three can be widely used in the antitheft reinforcing of outdoor easy pirate facility is installed by after the supporting use of adjustable spanner;
2, the utility model is simple in structure, and is equipped convenient, and antitheft reliable, cheap, social benefit is obvious.
