Abstract

The utility model discloses a multifunctional grounding clamp, which comprises an insulating rod, and a connecting plate is screwed on the upper end of the insulating rod, and the connecting plate is rotatably connected with a metal hook; the metal hook is an inverted U-shaped body, and one side of the U-shaped body is rotated A metal hook connecting plate is connected, and a hole is arranged on the connecting plate, and the hole is connected with the connecting hole on the connecting plate by bolts. Compared with the prior art, the multi-functional ground wire clamp of the utility model can adjust the rotation angle and the opening degree of the opening arbitrarily, and can be suitable for both square aluminum bars and cylindrical wires.

Description

A kind of multifunctional grounded wire clamp

Technical field

The utility model belongs to wire connection device, particularly relates to a kind of earthing clamp.

Background technology

In electric power system, columniform flexible conductor is used the hanging earthing clamp of long handle at present, square shaped aluminium row uses short handle hand held earthing clamp.It is longer that the hanging earth connection of long handle can be done, and the staff needn't ascend a height, just can be easily to cylindrical flexible conductor installing earth connection on relatively smooth ground.But square shaped aluminium row, the long handle wire clamp is just helpless, can only use short handle hand held earthing clamp, but the work that the staff can only ascend a height and emit the risk of direct contact electrification conductor to install earth connection.

Summary of the invention

Given this, the utility model purpose is to provide a kind of practicality multifunctional grounded wire clamp widely.

For solving above technical problem, the technical scheme that the utility model provides is, a kind of multifunctional grounded wire clamp is provided, and comprises an insulating bar, is connected with connecting plate in the insulating bar upper end, and connecting plate and metal hook are rotationally connected; Described metal hook is inverted U-shaped body, Yi Bian this U-shaped body wherein is connected with the metal hook connecting plate, is provided with a hole on this connecting plate, and the connecting hole on this hole and connecting plate is bolted.

Further, described inverted U-shaped body hollow comprises two holders and the guide rod between two holder tops, and guide rod and holder are slidably matched.

Preferably, be provided with metal clips on described holder.

Preferably, be provided with the wire connecting plate on described connecting plate.

Compared with prior art, multifunctional grounded wire clamp described in the utility model can be adjusted arbitrarily the aperture of the anglec of rotation and opening, can be fit to square aluminum row and also can be fit to the column type wire.The operating personnel uses 1 meter long insulating bar of every joint, can freely form random length in 1-4 rice, stand in ground or relatively firm plane can light square shaped aluminium row and the column type wire carry out earth connection and install.Be applicable to the column type wire ground connection of level installation when this multifunctional grounded wire clamp, the square aluminum row's that level is installed ground connection and the wire of vertically installation or aluminium row.

Embodiment

Describe below in conjunction with accompanying drawing and specific embodiment.

Referring to Fig. 1.The multifunctional grounded wire clamp that the present embodiment is described is by an insulating bar 1, connecting plate 2 and metal hook 3.Insulating bar 1 upper end hollow, in be provided with internal thread, connecting plate 2 lower ends are provided with external screw thread, insulating bar 1 can be threaded connection with connecting plate 2, therefore, insulating bar 1 can be dismantled at any time.Connecting plate is provided with wire connecting plate 22 on 2 stage casings, and wire connecting plate 22 is metal material, but external wire.Connecting plate 2 upper ends are provided with connecting hole 21, are bolted with hole on the metal hook connecting plate 31 of metal hook 3 lower ends.Metal hook 3 can rotate around bolt.Metal hook 3 is inverted U-shaped body, Yi Bian this U-shaped body wherein is connected with metal hook connecting plate 31, namely this U-shaped body can be done 360 ° of rotations around the axial line of metal hook connecting plate 31.This inverted U-shaped body hollow comprises that two add gripping member and the guide rod 32 between two holder tops, and guide rod 32 is slidably matched with holder.By being slidably matched of guide rod 32 and holder, can control the aperture of metal hook 3.Be provided with metal clips on holder, metal clips is between two holders, to increase metal hook 3 and wire or aluminium row's electric conductivity.

During use, the column type wire ground connection that level need to be installed keeps metal hook to be in vertical state and gets final product, as shown in Figure 1.The square aluminum row ground connection that level need to be installed gets final product metal hook, as shown in Figure 2 around the bolt half-twist.Need wire or the aluminium row ground connection that will vertically install, first with metal hook around the bolt half-twist, then the axial line half-twist of metal hook around connecting plate 31 got final product, as shown in Figure 3.

Be below only preferred implementation of the present utility model, should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection range of the present utility model should be as the criterion with the claim limited range.For those skilled in the art, within not breaking away from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
