Abstract
The utility model discloses an anti-theft nut with micro taper for a hard increasing integral shim with heat treatment, which has the advantages of simple structure, convenient assembly, theft prevention and reliability, and the utility model comprises a nut body (1), a nut bottom (2), a nut top (3), screw threads (4) at the inner wall of the nut body and a through hole at the inner wall of the nut body, wherein the outer wall of the nut body (1) is respectively provided with an outer opposite face (6) with micro taper at the outer wall of the nut body, an outer opposite angle (7) with micro taper at the outer wall of the nut body, a circumference plane (8) of an integral shim at the nut bottom and the circumference wall (9) of an integral shim at the nut bottom, which are in an integral structure, and the nut body (1) is a hard increasing work piece with heat treatment. The utility model, which is matched with an anti-theft sleeve of an inner opposite angle screw with micro taper to use and install, can be widely suitable for conducting the anti-theft and reinforcing installation of devices which are fixedly arranged at outdoor easily-robbed positions or the components of the devices.
Description
Technical field
The utility model is that a kind of equipment or its parts that relate to being fixedly installed in outdoor easy robber location carry out the fastening piece accessory that antitheft reinforcing is installed, and more particularly, it is a kind of anti-theft screw nut.
Technical background
To ending at present, owing to lack real effectively anti-theft screw and anti-theft screw auxiliary equipment, cause the facility objects such as electric power, communication, environmental protection 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.The non-standard fastener screw has carried out alternative use though have in a small amount before this, needs only imitated its dress, tears manual tool open, and is promptly still errorless according to stealing.
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, and is equipped convenient, and antitheft reliable heat treatment increases and connects pad tapered external angle anti-theft screw nut firmly.
The technological scheme that its technical problem that solves the utility model adopts is:
The utility model heat treatment increases and connects pad tapered external angle anti-theft screw nut firmly and comprise nut parent 1, female end 2, female top 3, parent inner thread 4 and parent inwall through hole 5; Be respectively equipped with on nut parent 1 outer wall outside the nut parent outer wall tapered external angle of linking body structure outside opposite 6, the nut parent outer wall tapered external angle that diagonal angle 7, female end of nut connect pad circumferential plane 8 and female end of nut connects pad peripheral wall 9; Nut parent 1 is hard workpiece for heat treatment increases.
The diameter of disjunctor pad circumferential plane of female end of described nut 8 is greater than the diameter at the outer diagonal angle 7 of nut parent outer wall tapered external angle.
The beneficial effects of the utility model are:
1, the utility model is the tapered external angle structure of utilizing on its nut parent outer wall, it through cover pack into heat treatment increase the recessed straight flute screw anti-theft of hard tapered external angle inner opposite angle cover and through complete fastening after, just can make all fastened things reach permanent antitheft purpose;
2, the utility model is after heat treatment increases hard processing, can prevent with hacksaw sawed-off and cause stolen;
3, the utility model is simple in structure, and is equipped convenient, and antitheft reliable, social benefit is obvious.
Description of drawings
Fig. 1 is the utility model embodiment linking body structure schematic representation.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described.
On nut parent 1, be respectively equipped with female end 2 of linking body structure, female top 3, parent inner thread 4 and parent inwall through hole 5; On nut parent 1 outer wall, be respectively equipped with outside the nut parent outer wall tapered external angle of linking body structure diagonal angle 7, disjunctor pad circumferential plane 8 of female end of nut and disjunctor pad peripheral wall of female end of nut 9 outside opposite 6, the nut parent outer wall tapered external angle; Nut parent 1 is hard workpiece for heat treatment increases.
Claims (2)
1, a kind of heat treatment increases and connects pad tapered external angle anti-theft screw nut firmly, comprise nut parent (1), female end (2), female top (3), parent inner thread (4) and parent inwall through hole (5), it is characterized in that: on nut parent (1) outer wall, be respectively equipped with diagonal angle (7), nut mother's end disjunctor pad circumferential plane (8) and nut mother end disjunctor pad peripheral wall (9) outside the outer opposite (6) of nut parent outer wall tapered external angle, nut parent outer wall tapered external angle of linking body structure; Nut parent (1) is hard workpiece for heat treatment increases.
2, heat treatment according to claim 1 increases and connects pad tapered external angle anti-theft screw nut firmly, it is characterized in that: the diameter of the female end disjunctor pad circumferential plane of nut (8) is greater than the diameter at the outer diagonal angle (7) of nut parent outer wall tapered external angle.
