Abstract
The utility model relates to a high voltage grounding bar for live working of an electrician. The utility model is composed of an insulating handle and a metal grounding clamp. The utility model is characterized in that a leading screw at the upper end of the insulating handle adopts a double-ended rectangular spiral buckle and is matched with a copper leading screw nut. The operation is quick, and labor is saved. A sliding conducting wire clip is provided with a spacing bolt which is opposite to an I-shaped ring groove at the top end of the leading screw, which leads the sliding conducting wire clip to tightly clamp a conducting wire. A clamp seat of the metal grounding clamp is provided with a rectangular groove for clipping a copper head of a grounding conducting wire. The separation angle of the groove and the insulating handle is equal to 45 DEG-90 DEG, which can lead the grounding conducting wire to be far away from the insulating handle. The operating safety can be ensured.
Description
The utility model relates to electrician's power tool, particularly is a kind of high-voltage earthing rod.
In the construction and maintenance of power circuit and equipment, usually need to make circuit or equipment ground.For ground connection under charged situation, will use the high-voltage earthing rod, and the necessary connection of high-voltage earthing rod is tight, firm, guarantees handling safety.
The purpose of this utility model be exactly to provide a kind of can safety work, easy to operate and the high-voltage earthing rod that is connected with lead or conductive plate that can be tight, firm.
For this reason and the design the high-voltage earthing rod, leading screw by insulation handgrip and its upper end is formed with the metallic clamp of band leading screw screw, metallic clamp links to each other with earth connection, metallic clamp is made up of with the slide wire card or the slip lower plate that are connected with the I-shaped annular groove on leading screw top with the screens bolt the lead hook or the train wheel bridge of band leading screw screw, and slide wire card or slip lower plate one side have the I-shaped groove can be along the straight-arm slippage of lead hook or train wheel bridge.
Safe ready is made in the clubs of the utility model high-voltage earthing, during ground connection, hold the insulation handgrip, catch on lead or conductive plate, rotate handgrip again, just but clamping wire or conductive plate because slide wire card or slip lower plate are to be connected with the I-shaped annular groove on leading screw top with the screens bolt, can guarantee that slide wire card or slip lower plate closely contact with lead or conductive plate.
For sharp work, reduce labor intensity, the leading screw screw of high-voltage earthing rod can be the copper feed screw nut that is embedded in lead hook or the train wheel bridge holder, and the spiral shell button of leading screw and feed screw nut is the double end rectangle.
In order to ensure handling safety, earth connection and the staff of holding insulating rod are kept at a distance, the lead hook of high-voltage earthing rod or train wheel bridge holder one side can be provided with the rectangular recess of holding earth lead copperhead, and the angle of rectangular recess and high-voltage earthing rod insulation handgrip is 45 ° to 90 °.
Below in conjunction with accompanying drawing the utility model is described.
Fig. 1 is one of a utility model embodiment schematic diagram.
Fig. 2 is two schematic diagrames of the utility model embodiment.
As shown in Figure 1, the high-voltage earthing rod is by the leading screw 5 of insulation handgrip 1 and its upper end and be embedded at copper feed screw nut 3 in the holder 4 and the hook 11 of aluminium matter lead and slide wire card 10 with screw 2 and form, the I-shaped annular groove 8 of the leading screw 5 pre-ends in the screens bolt being arranged on the slide wire card 10 and placing its shrinkage pool 9 is relative, slide wire card 10 1 sides have the I-shaped groove 12 can be along straight-arm 13 slippages of lead hook 11, and there is steel packing ring 6 I-shaped annular groove 8 lower ends, leading screw 5 tops.Leading screw 5 is the double end rectangle with the spiral shell button of copper feed screw nut 3.Holder 4 one sides of lead hook 11 have the rectangular recess 14 of holding earth lead 16 copperheads 15, and rectangular recess 14 is 60 ° with the angle of insulation handgrip 1.
As shown in Figure 2, the aluminium earth clip of high-voltage earthing rod is by straight-arm on the holder 4 13 and train wheel bridge 17, and leading screw 5 top lower plates 18 form, but close and firm ground be connected with conductive plate, other structure is identical with Fig. 1.
