Abstract
The utility model discloses a spring adjustable lead earth device, which comprises an insulating rod. A working head is arranged on the top of the insulating rod and articulated with a thread tension mechanism; one end of the articulated axle of the thread tension mechanism is a clamp arm and the other end is a pressure lever; a spring is arranged inside the working head and the spring props up the pressure lever tightly; a regulation cock is arranged inside the working head and is contacted and matched with the spring; the spring can be regulated by rotating the regulation cock, thus being bale to change the tensile force the pressure lever bore from the spring and regulating the chucking power of the clamp arm towards the electrical wire. The regulation cock is regulated according to the diameter of different electrical wires, which results in suitable chucking power of the clamp arm towards the electrical wire. The lead earth device of the utility model has the advantages of convenient use, good safety, good intensity and adjustability.
Description
Technical field
The utility model relates to a kind of electrician's power tool, relates in particular to a kind of lead earthing device.
Background technology
Often use earth connection at hotline maintenances such as electric power system, transmission lines, when safeguarding.China utility model patent 200620090677.X discloses a kind of distribution line earthing clamp.Be provided with insulating bar, be provided with the ground connection hook in the insulating bar upper end, an end of earth connection is connected with the ground connection hook, and its technical characterstic is to be provided with the upset pressing plate on the ground connection hook, the upset pressing plate is connected with the ground connection hook by rotating shaft, is provided with extension spring between upset pressing plate middle part and ground connection hook.This technology has solved existing earthing clamp and has easily blocked lead, tears technical problems such as hanging effort, damage wires open.
But the not high easy fracture of earthing device intensity in the prior art, spring are loosening easily, and the contact area of earthing device and cable is little, and the safety guarantee aspect is not very desirable.
Summary of the invention
The utility model provide a kind of esy to use, safe and reliable, intensity good, reconcilable lead earthing device.
The lead earthing device that a kind of spring is adjustable comprises insulating bar, and the insulating bar top is provided with working head, described working head is hinged with wire-clamping device, and an end of the jointed shaft of wire-clamping device is a jig arm, and the other end is a depression bar, be provided with spring in the working head, the spring top clamping depression bar.
Working head is provided with depression near the jig arm place, depression cooperate with jig arm can be firm with the electric wire clamping.
Working head is provided with the binding post that is used to connect earth lead.
Be provided with regulation cock in the working head, regulation cock and spring contact matching, by the rotation regulation cock, can regulating spring, so just can change the tension force of spring to depression bar, also just adjusted the clamping dynamics of jig arm, regulated regulation cock, made jig arm suitable the clamping dynamics of electric wire according to the different diameters of wire to electric wire.
The utility model lead earthing device is esy to use, safe and reliable, intensity good, can reconcile.
Description of drawings
Fig. 1 is the utility model lead earthing device structural representation;
Fig. 2 is the utility model lead earthing device clamping electric wire open structural representation of jig arm when in place;
Embodiment
Referring to accompanying drawing, the utility model lead earthing device comprises insulating bar 1, and insulating bar 1 top is provided with working head 2.
Working head 2 is hinged with wire-clamping device 3, and wire-clamping device 3 is roughly " L " type, is jig arm 5 at an end of the jointed shaft of wire-clamping device 3, and the other end is a depression bar 4, is provided with spring 7 in the working head 2, and spring 7 holds out against depression bar 4.
Working head 2 is provided with depression 10 near jig arm 5 places, depression 10 cooperate with jig arm 5 can be firm with the electric wire clamping.
Working head 2 is provided with the binding post 8 that is used to connect earth lead.
Be provided with regulation cock 6 in the working head 2, regulation cock 6 and spring 7 contact matching, by rotation regulation cock 6, can regulating spring 7, so just can change the tension force of 7 pairs of depression bars 4 of spring, also just adjusted the clamping dynamics of 5 pairs of electric wires of jig arm, regulated regulation cock 6, made the clamping dynamics of 5 pairs of electric wires of jig arm suitable according to the different diameters of wire.
When the utility model lead earthing device uses, ride on the electric wire 9 jig arm 5 places also drop-down, extruding along with electric wire 9, jig arm 5 can be opened, and the depression bar 4 meeting holddown springs 7 of wire-clamping device 3 other ends, when electric wire 9 advanced to depression 10 positions, jig arm 5 resetted under spring 7 effects electric wire 9 is limited in the depression 10.
