Abstract
The utility model relates to a pin twisted-off type antitheft nut, comprising a nut body and an external protecting jacket, wherein a cylindrical structure is formed at the outer side of the nut body, threads are arranged at the inner side of the nut body, the protecting jacket is internally provided with a hollow structure matched with the exterior of the nut body, and a withstanding surface preventing the nut body from penetrating through is arranged at one side of the protecting jacket. The pin twisted-off type antitheft nut is characterized in that a corresponding groove is arranged at the outer side bottom of the nut body, which is corresponding to the withstanding surface, and is internally provided with a pin. By adopting the structure, the antitheft nut has the advantages of easy installation, simple structure and difficult effectiveness loss.
Description
Technical field
The utility model relates to nut, and it is widely used in the facilities such as electric power, high ferro, highway, particularly a kind of anti-theft nut.
Background technique
Anti-theft nut has nut body and outside protecting cover; In the prior art; Nut body that has and protecting cover stick with glue and are connected together, because they bond together, just have the power of twisting off instability; Even bonding insecure, the easy shortcoming that lost efficacy of long storage time can appear, influenced the installation of whole anti-theft nut; The anti kickback attachment that has plenty of mounting spring, steel ball and so between the good protective coat of body, such device have complex structure, easy malfunctioning shortcoming.
Summary of the invention
The purpose of the utility model is exactly to above-mentioned shortcoming, and a kind of easy, simple in structure, as to be difficult for inefficacy pin turn-break type anti-theft nut of installing is provided.
The purpose of the utility model is achieved in that a kind of pin turn-break type anti-theft nut; Comprise nut body and outside protecting cover; The outside of nut body is that cylindrical structural, inboard have screw thread; Protecting cover inside has identical nut body outside hollow-core construction, a side and also has and keeping off the face of keeping out that nut body passes, and it is characterized in that: described nut body exterior bottom with keep out the face opposite position and have corresponding groove, have pin in the groove.
Say that further described pin also has the vestige of fractureing at nut body and protective coat surface of contact place.
Say that further described nut body inside also has anti-theft device, described pin also has the vestige of fractureing at the opening of nut body groove and protective coat groove.
The beneficial effect of the utility model is: the anti-theft nut of this spline structure has installs easy, simple in structure, as to be difficult for inefficacy advantage.
Description of drawings
Fig. 1 is the structural representation of the utility model pin turn-break type anti-theft nut.
Wherein: 1, nut body 2, protecting cover 3, keep out face 4, pin
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
As shown in Figure 1; Pin turn-break type anti-theft nut; Comprise nut body 1 and outside protecting cover 2, the outside of nut body 1 is that cylindrical structural, inboard have screw thread, and protecting cover 2 inside have identical nut body outside hollow-core construction, a side and also have the face of keeping out 4 that nut body passes that keeping off; It is characterized in that: described nut body 1 exterior bottom with keep out face 3 opposite positions and have corresponding groove, have pin 4 in the groove.
Say that further described pin 4 also has the vestige of fractureing at nut body and protective coat surface of contact place.
Say that further described nut body 1 inside also has anti-theft device, described pin also has the vestige of fractureing at the opening of nut body groove and protective coat groove.
Described anti-theft device is spring, steel ball, jump ring etc., is the technology of extensive use in the existing anti-theft nut technology.
When tightening this anti-theft nut, be screwed to a certain degree and continue to twist, can pin be fractureed, rethink like this and unload just impossiblely, play the effect of antitheft.
