Abstract
The utility model discloses a disassembly-preventing burglarproof nut which comprises a nut body and a screw hole, wherein the upper part of the nut body is a hexagonal nut, and the lower part of the nut body is a cylindrical nut, a concave ring groove is arranged between the hexagonal nut and the cylindrical nut to form a neck ring, and the hexagonal nut, the cylindrical nut and the neck ring are integrated into a whole. The disassembly-preventing burglarproof nut has the advantages of simple structure, low cost, convenient operation, high installation quality, good burglarproof effect and strong practicability.
Description
Technical field
The utility model relates to technical field of fastening, relates in particular to a kind of anti-dismounting anti-theft nut.
Background technique
Existing bolt and nut fastening piece commonly used; Be to be used for connecting between the mechanical part and installing fixing indispensable strength member, the bolt and nut fastening piece uses very convenient, installs easily; It is also easy to dismantle; But for the bolt and nut fastening piece that is in the open-air Infrastructure, it is very important that its Security just seems, like the bolt and nut fastening piece of using in the Infrastructure such as railway, highway bridge, electric power pylon, microwave communication tower.Because it can disassemble easily, therefore, the object of often being stolen or destroying by the lawless person causes the hidden danger that is absolutely unsafe for these Infrastructure or directly destroys.For addressing this problem, many people research and develop out diversified anti-theft nut, but these anti-theft nuts are not that anti-theft effect is bad, exist component more exactly, complex structure, and manufacture cost is high.
Summary of the invention
It is not enough be to solve existing technology, the utility model provide a kind of simple in structure, cost is low, easy to operate, good anti-theft effect, practical anti-dismounting anti-theft nut.
The utility model adopts following technological scheme: anti-dismounting anti-theft nut; Comprise nut body, screw; It is characterized in that: the top of described nut body is that hexagon nut, bottom are barrel nut; Offer concave ring groove between described hexagon nut and the barrel nut, form neck ring, described hexagon nut, barrel nut, neck ring are an integral body.
The thickness of described neck ring is below 1/4 of screwhole diameter.
The thickness of described neck ring is 1/8 of screwhole diameter.
The anti-dismounting of the utility model anti-theft nut is that hexagon nut, bottom are barrel nut owing to nut body is designed to top, offers concave ring groove between hexagon nut and the barrel nut, forms neck ring, and hexagon nut, barrel nut, neck ring are an integral body.When the anti-dismounting of the utility model anti-theft nut be connected with bolt fix after; Firmly rotate hexagon nut again; Neck ring receives the torsion that common hexagon nut transmits and brisement only stays barrel nut to be connected with bolt, and thief can't be pulled down barrel nut with general tool; Thereby play the antitheft effect, avoid stolen.
Produce strain, the function that has the lock bolt to exempt spring washer when simultaneously, neck ring receives torsion brisement that hexagon nut transmits.
Further, the thickness of described neck ring is below 1/4 of screwhole diameter, and the thickness of neck ring is corresponding to the strength limits of rotation hexagon nut, so the unified easily fastening balanced dynamics of tamper nut improves installation quality.
The anti-dismounting of the utility model anti-theft nut compared with prior art, its advantage is: simple in structure, cost is low, easy to operate, installation quality is high, good anti-theft effect, practical.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Sequence number among the figure: 1, hexagon nut; 2, screw; 3, barrel nut; 4, concave ring groove; 5, neck ring.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
According to shown in Figure 1; The anti-dismounting of the utility model anti-theft nut; Comprise nut body, screw 2, the top of described nut body is that hexagon nut 1, bottom are barrel nut 2, offers concave ring groove 4 between described hexagon nut 1 and the barrel nut 3; Form neck ring 5, described hexagon nut 1, cylindrical nut 3, neck ring 5 are an integral body; The thickness of described neck ring 5 is 1/8 of screw 2 diameters.
After the utility model and bolt are tightened, rotation hexagon nut 1, neck ring 5 receives torsion that hexagon nut 1 transmits and brisement; Only staying barrel nut 3 is connected with bolt; Thief can't be pulled down barrel nut 3 with general tool, thereby plays the antitheft effect, avoids stolen.
More than specified the mode of execution of the utility model, but this instance of just lifting for the ease of understanding should not be considered to be the restriction to the utility model scope.Equally; Any person of ordinary skill in the field all can be according to the technological scheme of the utility model and the description of preferred embodiment thereof; Make various possible being equal to and change or replacement, but all these changes or replacement all should belong to the protection domain of the utility model claim.
