For achieving the above object, the utility model provides a kind of short-circuit grounding wire folder, is used to screw the bolt on the distribution feeder pillar, which is provided with an earth connection terminal, and described short-circuit grounding wire folder comprises:
One wire clamp seat is provided with stepped through hole in it;
One wire clamp nut seat is located in the stepped through hole of described wire clamp seat, and the head end of described wire clamp nut seat has screwed hole, be used for described distribution feeder pillar on bolt be connected;
One spring is located in the stepped through hole of described wire clamp seat, is placed in the stage casing of described wire clamp nut seat, and its two ends are connected with the step of described wire clamp seat and the step contact of wire clamp nut seat respectively;
One positioning sleeve is provided with a shoulder hole in it, nested the fixedlying connected of head end inwall of the tail end outer wall of described positioning sleeve and described wire clamp seat, and the shoulder hole in the described positioning sleeve is used for cooperating with bolt on the described distribution feeder pillar
One rotation axis, its head end is fixedlyed connected with the tail end of described wire clamp nut seat.
Preferably, the tail end outer wall of described wire clamp seat is provided with at least one circular groove, and the outer wall of described arc groove and described wire clamp seat seamlessly transits.Circular groove is used for cooperating realization to locate with the rotary manipulation instrument that applies external force.
Preferably, the tail end of described rotation axis is provided with a setting element.Be used for and the rotary manipulation tool positioned that applies external force.
Preferably, the setting element of described rotation axis tail end is an alignment pin.
Preferably, the setting element of described rotation axis tail end is a needle roller.
Preferably, be provided with a spring housing between an end of described spring and the inwall of described wire clamp seat, be provided with another spring housing between the outer wall of the other end of described spring and described wire clamp nut seat.
During work, the positioning sleeve openend of earthing clamp is aimed at distribution feeder pillar M12 bolt position to be inserted, when the screw of wire clamp nut seat head end contacts with the M12 bolt, rely on the free yielding effect of spring in the earthing clamp, make screw can aim at the location with bolt, and realize that screw thread accurately meshes, finish combining of screw and bolt thus.The operator rotates rotating shaft with external force then, and this moment, the wire clamp seat of earthing clamp was motionless, and the wire clamp nut seat rotates with respect to the wire clamp seat, and then realizes tightening of M12 bolt.
The utility model is owing to adopted above technical scheme, this earthing clamp can arbitrarily be inserted according to the optional position of existing distribution feeder pillar inner bolt, be closely connected with bolt, and then tight a bolt, greatly alleviated working strength and difficulty, be convenient to use in various different occasions.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of a kind of short-circuit grounding wire folder of the utility model.
Embodiment
As shown in Figure 1, this embodiment is a kind of preferred version of a kind of short-circuit grounding wire folder of the utility model.This short-circuit grounding wire folder is used for the ground connection operation of the M12 bolt on the existing distribution feeder pillar, and it comprises: positioning sleeve 1, wire clamp seat 2, wire clamp nut seat 3, spring 4, rotation axis 5 and earth terminal 6.Wherein have stepped through hole in the wire clamp seat 2, be used to be provided with positioning sleeve 1, wire clamp nut seat 3, spring 4 and rotation axis 5, earth terminal is located on the wire clamp seat 2.Interior wire clamp nut seat 3, one ends of stepped through hole of being located at wire clamp seat 2 have internal thread hole, and the other end is fixedlyed connected with rotating shaft 5, and its screwed hole and M12 bolt are connected.Spring 4 is located in the stepped through hole of wire clamp seat 2 by a pair of spring housing, is placed in the stage casing of wire clamp nut seat 3, and spring 4 step and the step of wire clamp nut seat 3 by wire clamp seat 2 is spacing.The tail end outer wall of positioning sleeve 1 is nested with the head end inwall of wire clamp seat 2, and fixedly connected by trip bolt, and the shoulder hole in the positioning sleeve 1 is used for cooperating with bolt on the distribution feeder pillar.The head end of rotation axis 5 is fixedlyed connected with the ladder post tail end of wire clamp nut seat 3 by alignment pin, and the tail end of rotation axis 5 is provided with needle roller, when being used to apply rotation external force, with the throw location, circumferentially skids when preventing to rotate.
