Abstract
The utility model provides an unscrew bolt with anti-theft and anti-detachment functions. The end part of a cylinder bolt is provided with a recessed screw groove and screws for installing, the bolt is fixed by the screws, and the screws are reversely rotated out after the installation is finished so as to reach the purpose of anti-detachment. The utility model can be widely used for installation engineering with certain usage.
Description
The utility model relates to a kind of special bolt, especially a kind of anti-bolt of disassembling.
Present known bolt, it is made up of the body of bolt and nut, and nut is twisted and is fixed on the body of bolt during installation.But this bolt is when being used for the anti-special purpose of disassembling such as erection unit or casing, can disassemble easily from the bolt outside by spanner, links and fixing purpose thereby can only reach, and can not prevent disassembling.General bolt can not antitheft and anti-disassembling.
The purpose of this utility model is to provide a kind of anti-bolt of disassembling that can not arbitrarily disassemble.
The purpose of this utility model is achieved in that the termination of present known screw bolt is set to cylindrical body, and set up a concave type thread groove in cylindrical end, make a same installation screw directly of the thread groove with concave type simultaneously, when mounted screw is screwed in the thread groove, twist solid by (or hexagon head) swivel bolt of the notch on the screw, after installing, the counterrotating screw can produce it, thereby reaches the antitheft anti-purpose of disassembling.
Owing to take such scheme, can solve the antitheft anti-problem of disassembling of bolt preferably, use this bolt can effectively prevent to be mounted article and disassembled because of bolt and lose.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.Fig. 1 is the anti-organigram of disassembling bolt.Among the figure: 1, installation screw; 2, thread groove; 3, bolt; 4, nut.
In the organigram of the present utility model, illustrate that this anti-disassemble bolt and combined by bolt (3) and screw (1), nut (4), wherein nut (4) end is a cylindrical body, during use screw (1) screwed in the thread groove (2) on the bolt (3), it is solid that threaded bolt (3) and nut (4) are twisted, after the installation, screw (1) oppositely can be screwed out, thereby reach the anti-purpose of disassembling.
Claims (1)
