Abstract
The utility model discloses an Epsilon-type anti-theft screw spike manufactured by a quenching process for hardening without increasing brittleness. The Epsilon-type anti-theft screw spike is an anti-theft screw spike in a non-standard fastening member. The Epsilon-type anti-theft screw spike comprises an anti-theft screw spike body (1), a screw spike rod (2), a screw spike top (5), a spike top surface internally-concave hole (9) which are manufactured by the quenching process for hardening without increasing brittleness, wherein the spike top surface internally-concave hole (9) is internally provided with a conical bulge-type obstructive propping column (91); and the conical bulge-type obstructive propping column (91) in the spike top surface internally-concave hole is provided with a propping column outer-circumference taper wall (92) and a propping column top (93). The Epsilon-type anti-theft screw spike can be used for carrying out anti-theft fixation and installation on a large amount of electric facilities, telecom facilities and the like which are easy to be stolen and easy to be destroyed by terrorists after being matched with corresponding specifications and shapes of steel anti-theft nuts, a special mounting and dismounting wrench socket, a ratchet wheel handle auto-wrench and the like and has remarkable social benefits.
Description
Technical field
The utility model is the anti-theft screw in a kind of non-standard fastener; After the supporting uses such as anti-theft screw nut, assembly and Disassembly special tool wrench socket and ratchet lever autowrench of it and corresponding specification, shape and steel; Can be to being installed on outdoor easy robber in a large number, being prone to facilities such as the terrified electric power that destroys, telecommunications and carrying out fixed installation of security and used, its social benefit is obvious.
Background technique
To ending at present; Still lack real effectively, series product such as convenient, the reliable anti-theft screw of antitheft of mounting or dismounting and assembly and Disassembly special tool thereof; The facility that cause and be installed on outdoor easy robber in a large number, is prone to terrified destruction constantly is stolen and sold, and it has caused restriction and influence in various degree to people's production, life.
Summary of the invention
The purpose of the utility model is for overcoming deficiency of the prior art, provide a kind of simple in structure, adorns, tears open conveniently, and the reliable the utility model of guarding against theft increases with quenching and do not increase " mountain " font anti-theft screw technology that crisp technology is made firmly.
The utility model solves the technological scheme that its technical problem adopted:
The utility model increases with quenching and does not increase " mountain " font anti-theft screw that crisp technology is made firmly; Comprise with quenching and increase heptangle wall 12 and screw top end face inward recess bottom surface 13 in anti-theft screw ailing body 1, screw ailing bar 2, screw ailing bar screw thread 3, screw ailing bar bottom surface 4, screw screw top 5, screw top excircle tapered wall 6, screw top bottom surface 7, screw top end face 8, screw top end face inward recess 9, screw top end face indent hole wall 10, the interior five jiaos of walls 11 of screw top end face inward recess or the screw top end face inward recess that does not increase crisp technology firmly and make; In screw top end face inward recess 9, be provided with in the screw top end face inward recess conical protruding high formula obstacle property top and support post 91, conical protruding high formula obstacle property top is supported and is respectively equipped with the top on the post 91 and supports post excircle tapered wall 92 and support post capital 93 with the top in screw top end face inward recess.
The beneficial effect of the utility model is:
1, after the supporting use such as the anti-theft screw nut of the utility model and corresponding specification, shape and steel, assembly and Disassembly special tool wrench socket and ratchet lever autowrench; Can be to being installed on outdoor easy robber in a large number, being prone to facilities such as the terrified electric power that destroys, telecommunications and carrying out fixed installation of security and used, its social benefit is obvious;
2, the utility model is simple in structure, adorns, tears open conveniently, and antitheft is reliable, and social benefit is good.
