Abstract
The utility model discloses a hard and tough anti-theft screw nut with multi-taper, which has the advantages of simple structure, low fabrication cost, convenient assembly and disassembly and anti-theft reliability. A taper wall (6) with medium taper at the bottom section of the nut, a taper wall (7) with small taper at the middle section of the nut, a taper wall (8) with big taper at the top section of the nut are respectively arranged on outer wall of a screw nut body (1) of the utility model; in addition, the taper wall (6), the taper wall (7) and the taper wall (8) are in a connected structure. The utility model is made of steel material which is processed in a quench hardening mode by heat treatment. Only a special anti-theft screw wrench of which the taper wall of the outer circumference has purpose-made hard teeth can screw in threads or screw out threads, so that the utility model has the anti-theft effect if the threads are screwed in tightly, and the utility model can be disassembled if the threads are screwed off. The utility model is widely suitable for the anti-theft and reinforcing installation of devices or other components which are fixedly installed at easily-stolen sections outdoors.
Description
One, technical field
The utility model is a kind of fastening piece that the mount object is used that relates to, and more particularly, it is a kind of anti-theft screw accessory.
Two, background technique
Known fastener screw mother, the alternate structure of rib that all has respective numbers with the rib plane, conventional general various spanner and sleeve its screw thread of just advancing and retreat, even the fastening piece of indivisible distortion is arranged, also as long as with hard tooth pipe tongs or make utmost point light instrument its screw thread of just advancing and retreat by oneself, now equipment such as communal facility is fixedly installed in the increasing of outdoor easy robber location, and thief promptly utilizes the shortcoming that this fastening piece can not be antitheft, steal and sell illegal activity thereby carry out it, it has caused harm and destruction in various degree to society and people.
Three, 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, cheap, adorning, tear open conveniently, and is antitheft reliable, the tangible the utility model technology of social benefit.
The technological scheme that its technical problem that solves the utility model adopts is:
The utility model---the hard and tough anti-theft screw nut of many taperings, forms by round tube hole 4 and parent inner hole wall screw thread 5 in female end 2 of the hard and tough anti-theft screw nut parent 1 of many taperings, nut, the female top 3 of nut, the parent, on hard and tough anti-theft screw nut parent 1 outer wall of many taperings, be respectively equipped with in the base section of linking body structure tapering tapered wall 6, female stage casing conelet degree tapered wall 7 an and female top section tapering tapered wall 8 greatly.
Tapering tapered wall 6 diameters are greater than the diameter of female stage casing conelet degree tapered wall 7 in the described base section, and female stage casing conelet degree tapered wall 7 diameters are again greater than the diameter of the big tapering tapered wall 8 of mother's section of top; The number of degrees of tapering tapered wall 6, female stage casing conelet degree tapered wall 7 and the big 8 three sections linkage section taperings of tapering tapered wall of female top section are inconsistent in the base section; Little, the many tapered walls of indentation in big top at the bottom of the Quan Bicheng are ended on female top 3 from female end 2 of nut to nut; Hard and the tough anti-theft screw nut parent 1 of many taperings adopts the high-quality steel to increase the brinelling fire through heat treatment and is processed into, and its hardness is stiffer than the hardness of the hard tooth of conventional pipe tongs, but is softer than the hardness of the hard tooth of excircle tapered wall special spanner for safety screw.
The beneficial effects of the utility model are:
1, female top outer wall adopts many tapered walls structure of many walls section, indentation, different taperings, and it can make all conventional stealing tools all can reduce it to the utmost and touch the stressed supporting point length of wall, has strengthened the effect of anti-back screw thread;
2, parent adopts the high-quality steel to increase the brinelling fire through heat treatment to be processed into, and makes hard tooth such as pipe tongs gnaw card and does not go into to follow closely external wall and produce slip, makes its screw thread that do not fall back, thereby reaches antitheft purpose;
3, the utility model is furnished with the special Patent right excircle tapered wall special spanner for safety screw that has separately, the hardness of the hard tooth of this special spanner is stiffer than the hardness of the utility model parent outer wall, the hard tooth of this special spanner can be gnawed easily to be snapped in the utility model parent outer wall, can be antitheft thereby all fastened things all can be reached screw, withdraw from the purpose that can remove;
4, the utility model is simple in structure, and is cheap, adorns, tears open conveniently, antitheft reliable, obvious social benefit.
Four, description of drawings
Accompanying drawing is the utility model structural representation.Wherein 1 is the hard and tough anti-theft screw nut parent of many taperings, and 2 is female end of nut, and 3 is the female top of nut, 4 is round tube hole in the parent, and 5 is parent inner hole wall screw thread, and 6 is tapering tapered wall in the base section, 7 is female stage casing conelet degree tapered wall, and 8 is the big tapering tapered wall of female top section.
Five, embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Be respectively equipped with female end 2 of nut, the female top 3 of nut, the interior round tube hole 4 of parent and the parent inner hole wall screw thread 5 of linking body structure on the hard and tough anti-theft screw nut parent 1 of many taperings in the accompanying drawings; On hard and tough anti-theft screw nut parent 1 outer wall of many taperings, be respectively equipped with tapering tapered wall 6 in the base section, female stage casing conelet degree tapered wall 7 and the big tapering tapered wall 8 of female top section; Hard and the tough anti-theft screw nut parent 1 of many taperings increases brinelling fire workpiece for heat treatment, and its hardness is stiffer than the hard tooth hardness of pipe tongs, but is softer than the hardness of the hard tooth of excircle tapered wall special spanner for safety screw.
The utility model is loaded on the hard and tough anti-theft screw of many taperings and the utility model string in the fixed hole of corresponding object earlier when equipped the use, again with one or two excircle tapered wall special spanner for safety screw continuation it is rotated to complete fastening getting final product; When it meet to need is removed, if this special spanner through just, after the back side is inverted, during again by contrary clockwise direction switching, just can withdraw from screw thread easily, to screw energy antitheft thereby reach, and withdraws from the purpose that can remove.
