Abstract
The utility model discloses an antitheft foot nail which is used on transmission lines, comprising a foot nail body screw bolt, an adjusting nut, a movable steel column and a scotch tape. A thread end of the foot nail body screw bolt is processed with an inclined wedge slot, the movable steel column is arranged in the inclined wedge slot, and the movable steel column in the inclined wedge slot can be fixed by the scotch tape which is fixed on the movable steel column. The installation of the utility model is completely the same as common foot nails, owing to the structure, the utility model has the advantages of simple structure, reliable safety, good antitheft performance, convenient installation and construction, low cost and non-easy dismounting.
Description
Technical field: the utility model discloses a kind of pin nail that on transmission line of electricity, uses, a kind of specifically antitheft pin nail.
Background technology: existing concrete wire pole pin nail is to be made of screwed bolt of an end and the adjusting nut on it, and pin oncomelania bolt is by fixing in the screw that is screwed into the concrete wire pole member by the screw thread on it.Its effect be for the operating personnel up and down electric pole step on pedal used.The weak point of this pin nail is in particular in; Pin oncomelania bolt afterbody and adjusting nut are easy to be disassembled by the general general tool of human, thereby the pin nail is stolen, and the service work of inconvenient circuit is stayed potential safety hazard for the upkeep operation personnel, and causes economic loss to electric power enterprise.
Summary of the invention: the purpose of this utility model be to provide a kind of simple and reasonable, safe, reliable theftproof performance good, be convenient to the antitheft pin nail of transmission line of electricity installing and construct.
The purpose of this utility model is to realize like this, this antitheft pin nail comprises pin nail main body bolt, adjusting nut, movable steel column, adhesive tape, the end of thread of its pin nail main body bolt is processed with oblique shape wedge groove, movable steel column is set in the oblique shape wedge groove, and the movable steel column in the oblique shape wedge groove is fixed by the adhesive tape that is provided with on it.
The utility model has been owing to adopted above-mentioned structure, have simple and reasonable, safe, reliable, theftproof performance is good, be convenient to install and construction, cost are low, the characteristics that are difficult for being disassembled, and the safe operation of assurance transmission line of electricity is had significant meaning.
Description of drawings:
Fig. 1 is the antitheft pin nail of a transmission line of electricity overall structure schematic diagram.
Fig. 2 is the utility model A-A sectional drawing.
The specific embodiment:
Shown in accompanying drawing 1,2: this antitheft pin nail comprises pin nail main body bolt 1, adjusting nut 2, movable steel column 3, adhesive tape 4, the end of thread of its pin nail main body bolt 1 is processed with oblique shape wedge groove 5, movable steel column 3 is set in the oblique shape wedge groove 5, and the movable steel column 3 in the oblique shape wedge groove 5 is fixing by the adhesive tape 6 that is provided with on it.
Mode of occupation: product of the present invention is installed and common pin nail is installed identical, the end of thread of when mounted pin being followed closely main body bolt 1 is screwed in the electric pole pin oncomelania hole clockwise, adhesive tape 6 on the pin nail main body bolt 1 can break away from pin nail main body bolt 1 along with being screwed into of bolt, movable steel column 3 in the oblique shape wedge groove 5 is in the groove crack of broad in the oblique shape wedge groove 5 when the pin nail is installed, and the friction factor between movable steel column 3 and screw is little; When rotating counterclockwise pin nail main body bolt 1, movable steel column 3 rolls to oblique shape wedge groove 5 narrower groove cracks, and the extruding force between movable steel column 3 and screw increases gradually, thereby by force that bolt 1 is stuck, reaches antitheft purpose.
