The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of easy to use, connect reliable Portable power construction grounding device.
The purpose of this utility model is achieved in that a kind of Portable power construction grounding device, described device includes insulating bar, described insulating bar top is connected with shank (11) by universal joint, described shank top cross is provided with a top rail, on described shank, slide and be provided with a movable crosspiece, this movable transverse gear is in top rail below, and top rail parallels setting with movable crosspiece, have a vertical oil cylinder arranging to be fixed on shank, and the piston rod of oil cylinder is connected in the bottom of movable crosspiece.
A kind of Portable power construction grounding device of the utility model, described insulating bar is fixed with a ballhead, and described shank bottom is provided with a hemisphere draw-in groove embedding for ballhead, thereby has realized the universal hinging of insulating bar and shank.
A kind of Portable power construction grounding device of the utility model, described shank is vertically provided with rectilinear orbit, is provided with the slide block inserting in rectilinear orbit on described movable crosspiece.
A kind of Portable power construction grounding device of the utility model, the bottom of described top rail and the top of movable crosspiece all have the bayonet socket of curved setting, and the opening surface opposite of two bayonet sockets arranges.
A kind of Portable power construction grounding device of the utility model, is coated with the holding piece of a curved setting, and is connected with flexible member between bayonet socket and holding piece on described bayonet socket.
A kind of Portable power construction grounding device of the utility model, described flexible member is spring, and this spring one end is connected with the bottom of flexible member, and the other end is connected with the inwall of bayonet socket.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is by the design of universal joint, make angular adjustment convenient, thereby can make cable better laminating top rail of the present utility model and movable crosspiece, and the bayonet socket by top rail and movable crosspiece designs, further improve laminating contact effect, meanwhile, the holding piece covering on bayonet socket and flexible member make laminating more tight, increase the reliability connecting, improved security performance of the present utility model.
