Abstract
The utility model discloses a universal anti-falling ground wire clamp, and the clamp comprises a hollow insulating operating rod and a wire clamp joint. The wire clamp joint comprises an upper clamping board and a lower clamping board, which are connected together through a tensioning torsional spring. An upper groove is disposed under the upper clamping board, and a lower groove is disposed above the lower clamping board. The opening of the upper groove is corresponding to the opening of the lower groove. The lower end part of the opening end of the upper clamping board is distributed in an acute-angle manner, and the upper end part of the lower clamping board corresponding to the upper clamping board is also distributed in the acute-angle manner, wherein the two acute angles are 80 degrees, thereby enabling the opening end of the wire clamp joint to be duckbilled. The hollow insulating operating rod and the lower clamping board are in an all-in-one structure, and the upper clamping board is connected with a pulling rope in the hollow insulating operating rod and a pressing handle through the tensioning torsional spring. The cylindrical wall of the lower end of the interior of the hollow insulating operating rod is provided with a strip-shaped opening. The pressing handle moves up and down through the strip-shaped opening, thereby further driving the upper clamping board to be opened or closed through the pulling rope.
Description
Technical field:
The utility model relates to a kind of managing security tools and instruments that a kind of power industry is generally applied, and particularly relates to a kind of general anti-fall grounding wire wire clamp.
Background technology:
At present, the portable grounding wire device that China electric power system is used, has according to the classification of joint form: the types such as single tongue formula, double tongue type, spiral press formula, hold flat, hedgehog hydnum formula.Wherein single tongue formula, double tongue type are mainly used in circuit or bus and have a power failure and use while doing safety measure; Spiral presses formula, hold flat, be mainly used in busbar has a power failure and uses while doing safety measure.Grounding wire device exists the reason of various ways to be mainly, for meeting the needs of difform equipment in the time that safety measure is done in power failure.
Utility model content:
Technical problem to be solved in the utility model is: a kind of difficult drop-off, safe and reliable general anti-fall grounding wire wire clamp are provided.
The technical scheme that the utility model is taked for technical solution problem is:
A kind of general anti-fall grounding wire wire clamp, comprise hollow insulating bar and wire clamp joint, described wire clamp joint comprises train wheel bridge and lower plate, between described train wheel bridge and lower plate, link together by tightening up torsion spring, below train wheel bridge, be provided with upper groove, be provided with low groove above lower plate, the groove mouth of described upper groove and low groove in correspondence with each other, the bottom of described train wheel bridge openend is acute angle and distributes, and the upper end of corresponding lower plate is also acute angle distribution with it; Described hollow insulating bar and lower plate are integral type structure, the pull rope of described train wheel bridge by tightening up torsion spring and hollow insulating bar inside with press handle and be connected, in hollow insulating bar, on the cylindrical wall of lower end, be provided with strip gab, described in press handle and move up and down by strip gab and then drive train wheel bridge to open or closed action by pull rope.
Two acute angles of the upper end of the bottom of described train wheel bridge openend and lower plate openend are 80 degree angles, make the openend of wire clamp joint be duckbill shape.
The corner position of the described train wheel bridge opposite side corresponding with openend is provided with connection fastening bolt, and earth connection is fixed on train wheel bridge by connecting fastening bolt.
The described handle of pressing is processed by insulating material.
When use, press the handle of pressing of the present utility model, pull rope tensioning, tightens up torsion spring stressed, and train wheel bridge is opened, and the wire clamp that needs ground connection is held in to the notch place of upper groove and low groove; Unclamp the handle of pressing of the present utility model, train wheel bridge and lower plate closure, the notch of upper groove and low groove is also thereupon closed, has avoided the phenomenon of wire dropping.
Because the bottom of the utility model train wheel bridge openend is acute angle distribution, the upper end of corresponding lower plate is also acute angle distribution with it, two acute angles are 80 degree angles, make the openend of wire clamp joint be duckbill shape, the narrow rear hem width in front, can effectively prevent the obscission of earth lead, simple in structure, safe and reliable, easy to use, there is good practical value and marketing prospect.
