Abstract
An antitheft fastening device comprises a bolt, a nut matched with the bolt and an installation handle for driving the nut, wherein the nut is in a cylindrical shape, concave portions are arranged on the nut in array mode, and correspondingly the installation handle is provided with protrusion portions arranged in array mode. Due to the fact the nut is provided with the concave portions arranged in array mode, and correspondingly the installation handle is provided with the protrusion portions arranged in array mode, the protrusion portions are inserted into the concave portions, and then the installation handle is rotated to screw up the nut. Due to the nut in a cylindrical shape, an ordinary wrench has difficulty in screwing off the nut, and the antitheft function is obtained.
Description
Technical field
The utility model relates to a kind of antitheft securing means.
Background technique
At present, China to be used for the fastening piece on the facilities such as electric power pylon all be common angle of cut bolt and hexagon nut basically.And carry out installation and removal through instruments such as spanners.Because instruments such as spanner are very common socially, thereby often cause the iron tower material stolen, and then can cause serious accident.
Summary of the invention
The technical problem that the utility model will solve provides a kind of easy to operate, simple in structure antitheft securing means.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: comprise bolt, reach and the bolt nut engaged, and be used for the mounting knob of drive nut; Said nut is cylindrical, and said nut array arrangement has depressed part, and the corresponding array arrangement of said mounting knob has lug boss.
Further, the degree of depth of said depressed part is identical with the height of lug boss.
The antitheft securing means of the utility model, because said nut array arrangement has depressed part, the corresponding array arrangement of said mounting knob has lug boss; After lug boss inserted depressed part; Rotate mounting knob again, thereby with nut screwing clamping, because nut is cylindrical; Be difficult to turn on through common wrench, thereby play the effect of antitheft.
Description of drawings
Fig. 1 is the schematic representation of the utility model antitheft securing means.
Embodiment
In the present embodiment, with reference to Fig. 1, said antitheft securing means comprises bolt 1, reaches and bolt 1 nut engaged 2, and is used for the mounting knob 3 of drive nut 2; Said nut 2 is cylindrical, and said nut 2 array arrangements have depressed part 20, and said mounting knob 3 corresponding array arrangements have lug boss 30.After lug boss 30 inserted depressed parts 20, rotate mounting knob 3 again, thereby nut 2 is tightened,, be difficult to turn on, thereby play the effect of antitheft through common wrench because nut 2 is cylindrical.
Wherein, the degree of depth of said depressed part 20 is identical with the height of lug boss 30.
The antitheft securing means of the utility model, because said nut array arrangement has depressed part, the corresponding array arrangement of said mounting knob has lug boss; After lug boss inserted depressed part; Rotate mounting knob again, thereby with nut screwing clamping, because nut is cylindrical; Be difficult to turn on through common wrench, thereby play the effect of antitheft.
Below the utility model is done a detailed description; The above is merely the preferred embodiment of the utility model, when not limiting the utility model practical range; Be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
