The invention discloses a double-rail adjustable ground clamp. The double-rail adjustable ground clamp is provided with a ground caliper head and an insulating rod, wherein the ground caliper head isconnected with the insulating rod and is a semi-open frame formed by a 7-shaped upper clamping arm and an L-shaped lower clamping arm; the 7-shaped upper clamping arm comprises a cross arm A and a vertical arm A; a stop hook is arranged at the end head of the outer side of the cross arm A; a sliding groove is formed in the vertical arm A; a ground bolt is arranged below the sliding groove of the vertical arm A; the L-shaped lower clamping arm comprises a cross arm A' and a vertical arm A'; at least one adjusting stud is arranged on an outer side wall of the vertical arm A'; the adjusting studspass through the sliding groove of the 7-shaped upper clamping arm and are fixed by using locking nuts; a guide rail is arranged in an inner wall of the vertical arm A' and is connected with one sideof a pressure block; the bottom of the pressure block is connected with one end of a screw; the other end of the screw passes through the cross arm A' of the L-shaped lower clamping arm and is connected with one end of the spring; and the other end of the spring is connected with the insulating rod. The double-rail adjustable ground clamp is simple in structure and convenient to use, the openingdegree of a ground caliper bayonet is improved, and the double-rail adjustable ground clamp cannot spin when a rectangular bus bar is firmly locked and tightened.
Description
technical field [0001] The invention relates to the field of electric equipment, in particular to a double-track adjustable grounding clamp. Background technique [0002] In the current power system, various types of power equipment are developing towards miniaturization and compactness from the consideration of saving and occupying space. There is no problem with the normal operation of the equipment, but after a period of operation, the equipment must be powered off for maintenance, and the maintenance must be grounded. Conventional power tools are temporarily grounded on the rectangular busbar of the transformer low-voltage busbar bridge, which needs to be elevated and the opening width of the grounding jaw is limited. Easy to assemble, safe and fast grounding tools on rectangular busbar bridges are essential. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to improve the above shortcomings, to provide a simple structure and convenient manufac...
