The clamp holder of moving clamping plate and quiet clamping plate connects respectively protective earthing line and connecting plate; Connecting plate end is connected with the screw rod of insulating bar end by screw thread.
Further, the jaws of described clamping plate inner side is provided with the clamp notch of arc.
Further, described insulating bar is Multi section bar body structure, passes through screw thread or clamp connection between each body of rod.
The utility model has the advantages that: simple and reasonable, operation is reliable, realizes articulating fast of large corner pole interior angle side line grounding wire, and wire clamp and insulating bar are threaded connection, easy disassembly; Greatly reduce difficulty of construction, effectively raise operating efficiency.
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is elaborated.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In figure: 1, quiet clamping plate, 2, moving clamping plate, 3, driving lever, 4, long guide through hole, 5, connecting plate, 6, insulating bar, 7, protective earthing line.
Embodiment
As can be seen from Figure 1, the utility model comprises binding clip, connecting plate 5, insulating bar 6, protective earthing line 7; Insulating bar 6 is Multi section bar body structure, and between each body of rod, by screw thread or clamp connection, the end of first segment insulating bar 6 is provided with the screw rod being connected with binding clip; Binding clip is made up of quiet clamping plate 1, moving clamping plate 2, and two clamping plates is oppositely arranged, middle part is articulated and connected by rotating shaft; The leading portion of two clamping plate forms jaws, and back segment is clamp holder, connects in the rotating shaft of dynamic and static clamping plate back-moving spring is housed, and the inner side of pressing two clamping plate handles is pushed up respectively at back-moving spring two ends, and binding clip is kept closed; The jaws inner side of quiet clamping plate 1 and moving clamping plate 2 is provided with the clamp notch of arc, increases the contact area of clamping plate and wire, and reduces the damage of wire clamp to wire.
The jaws section of quiet clamping plate 1 is provided with longitudinal long guide through hole 4, and long guide through hole 4 is interior is laterally equipped with a position-limitting pin, and the two ends of this position-limitting pin are fixed on long guide through hole wall; The jaws section of moving clamping plate 2, by the bearing pin driving lever 3 that is articulated and connected, is stretched out in the long guide through hole 4 of driving lever 3 outer ends by quiet clamping plate, makes driving lever 3 in the time that bearing pin swings, and outer section of driving lever moves growing guide through hole 4; Driving lever 3 is provided with the draw-in groove coordinating with the position-limitting pin in long guide through hole 4, and this draw-in groove opening is towards wire clamp front opening side.
The clamp holder of two clamping plates connects respectively protective earthing line 7 and connecting plate 5; In the present embodiment, the clamp holder of moving clamping plate 2 is bolted fixing protective earthing line 7, and the other end of protective earthing line 7 is connected with ground connection clamp, and protective earthing line 7 is the multiply annealed copper wire with sheath; Connecting plate 5 is fixed on by riveted joint on the clamp holder of quiet clamping plate 1, and connecting plate 5 ends are provided with screw, and is connected with the screw rod of insulating bar 6 ends.
Use the utility model to carry out large corner pole interior angle side line grounding wire while articulating, staff stands on cross arm of tower, utilize connecting plate 5 binding clip to be assemblied on the screw rod on insulating bar 6 tops, by the clamp holder of jointing clamp, jaws is opened, stir driving lever 3 draw-in groove on driving lever 3 is withstood on the position-limitting pin in the long guide through hole of quiet clamping plate 1, support dynamic and static clamping plate and make binding clip keep open configuration; Hand-held insulating bar 6 is delivered to binding clip at the wire place of shaft tower corner inner angle side, make wire enter jaws and touch driving lever 3, driving lever 3 swings along long guide through hole and swings to jaws inner side (i.e. the hinged place of two clamping plate), two clamping plate lose support, closed clamping wire under the effect of back-moving spring, then rotating insulated bar, makes insulating bar 6 separate with binding clip.
