Abstract
The utility model relates to a screw, in particular to an anti-theft screw used for fastening parts or members in the field operation of a power system, a communication system, an expressway and the like. The anti-theft screw comprises a nut, a bolt and a pin block, wherein the nut is internally provided with a groove which extends from the bottom surface of the nut; the bolt is externally provided with a groove along the direction of a bolt bar; and the pin block is provided with a cavity structure formed by buckling the groove of the nut and the groove of the bolt, and the pin block is equal to or greater than the cavity dimensionally. By adopting the structure, the anti-theft screw has the characteristics of low cost and convenient processing and installation.
Description
Technical field
The utility model relates to a kind of screw, particularly relate to a kind of in field facilities such as electric power system, communication system and expressway the anti-theft screw of fastenings or member.
Background technique
The anti-theft screw of being produced in the prior art is generally sought technological scheme at nut on this, and such nut has the processing trouble, caused the high shortcoming of cost, uses inconvenience, also needs special tool when mounted, and the use of anti-theft nut is restricted.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned shortcoming, and the anti-theft screw that a kind of anti-theft effect is better, cost is low, easy for installation is provided.
The purpose of this utility model is achieved in that anti-theft screw, it is characterized in that: comprise nut, bolt and pin block, the inside of described nut has the groove that extends from the nut bottom surface, described bolt outside has along the groove of tightening latch direction, and the groove that described pin block has a nut is equal to or greater than this cavity facing to this pin block on the structure of the formed cavity of groove of bolt, the size.More convenient in order to install, the groove of described nut or the groove of bolt have a plurality of.
The beneficial effects of the utility model are: because adopted that above structure, such anti-theft screw have that cost is low, installation and processing characteristics easily.

Fig. 2 is the longitudinal section structural representation after the utility model anti-theft screw is installed
Wherein, 1, nut 2, bolt 3, pin block 4, groove
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, anti-theft screw, it is characterized in that: comprise nut 1, bolt 2 and pin block 3, the inside of described nut 1 has the groove 4 that extends from the nut bottom surface, described bolt 2 outsides have the groove 4 along the tightening latch direction, the groove that described pin block 3 has a nut is equal to or greater than this cavity facing to this pin block on the structure of the formed cavity of groove of bolt, the size, like this after nuts and bolt is screwed to certain position, their groove faces toward, and pin block is pounded with hammer played antitheft purpose therein.
The height of described pin block is not more than the height of the groove of nut, is in order further to reach better effect, just can not appear after the pin block pin is entered like this, prevent to extract pin block, further playing antitheft purpose, as shown in Figure 2.
The groove of described nut or the groove of bolt have a plurality of, at this moment nut rotate a circle have a plurality of can the chance relative with bolt indentation, use more convenient.
Claims (2)
1. anti-theft screw, it is characterized in that: comprise nut, bolt and pin block, the inside of described nut has the groove that extends from the nut bottom surface, described bolt outside has along the groove of tightening latch direction, and the groove that described pin block has a nut is equal to or greater than this cavity facing to this pin block on the structure of the formed cavity of groove of bolt, the size.
