Summary of the invention
The purpose of this utility model is to provide a kind of reversible short-circuit grounding wire wire clamp, due to the adjustable angle of ground clamp and insulating bar, therefore earthing wire clip can from multiple different direction, multiple different angle is close to wire, and with most suitable angle and wire clamping connection, make up former earthing clamp aloft wire install station limited time cannot from the drawback of suitable angle and wire clamping connection, the ground connection of wire is worked more convenient safety.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of reversible short-circuit grounding wire wire clamp, comprise ground clamp, movable connector, A side fixed head, B side fixed head, the described A side fixed head side of being fixed on ground clamp vertical with B side fixed head, movable connector is hinged between A side fixed head and B side fixed head, A side fixed head being provided with pin joint is the cambered way hole in the center of circle, some joint fixed card slots are had in the arranged outside in cambered way hole, joint on movable connector is fixed cassette tape and is moved movable connector and move along skidway hole, when joint fix inlay card enter joint fixed card slot time, angle between movable connector and ground clamp is fixed.
Described movable connector comprises connector main body, the fixing card of joint, spring, the axle journal that card fixed by joint is arranged in the through hole in connector main body through cambered way hole, one end dop B that card fixed by joint is embedded in connector main body, other end dop A is embedded in joint fixed card slot, and spring housing is connected on joint and fixes on the axle journal of card.
Described joint is fixed card and is comprised dop A, dop B, axle journal, and dop A and dop B is separately fixed at the two ends of axle journal.
Compared with prior art, the beneficial effects of the utility model are:
A kind of reversible short-circuit grounding wire wire clamp and earthing method, due to the adjustable angle of ground clamp and insulating bar, therefore earthing wire clip can from multiple different direction, multiple different angle is close to wire, and with most suitable angle and wire clamping connection, make up former earthing clamp aloft wire install station limited time from the drawback of suitable angle and wire clamping connection, the environment for use that various need carry out suspension short-circuit grounding wire cannot be may be used for.Have structure simple, reasonable in design, use flexible, practical feature, be conducive to popularity.
