Degree, makes wire clamp make pendular movement, clip is hung on wire using impulsive force, and this method needs operator to have skilled skill
Ingeniously, success rate very bottom, wastes time and energy.
Another kind is hung using insulating bar.This earthing clamp needs wire clamp is fixed on insulating bar first
On, rotation process bar is tightened in wire clamp on wire.This earthing clamp needs certain experiences when hanging, and the dynamics tightened is difficult to
Grasp, loose contact between clip and wire often occurs in Jing to be caused to produce induction discharge between clip landing or wire and wire clamp, burns out
Wire clamp and wire, cause production accident, it is impossible to play the purpose for ensureing job safety.Hung using action bars and require operating personnel
Carry earth lead, electroscope etc. and will also carry action bars simultaneously, also action bars insulating properties will be detected before work.For
Situation in larger distance, will also lengthen to action bars on tower, and operation difficulty is big, and danger coefficient is high.
More than several its mode of operation technical difficulty of existing wire clamp it is big, take time and effort, complex procedures, make natively not abundant
The interruption maintenance time it is more nervous.Production plan has been had a strong impact on, work efficiency has been reduced.

This utility model is further elaborated below by way of the drawings and specific embodiments.
Description of the drawings：
Fig. 1 is dimensional structure diagram of the present utility model；
Fig. 2 is main structure diagram of the present utility model；
Overlooking the structure diagrams of the Fig. 3 for limiting plate.
Specific embodiment：
With reference to shown in Fig. 1 to Fig. 3, a kind of wired earth wire clamp with double hanging wire patterns, including wire clip body, springboard 4,
Diverter 3, limiting plate 10, latch 9, insulating cord 7, arm-tie 5 and connecting plate 6.Wherein, wire clip body is divided into wire clip body 1 with
The middle part of wire clip body 2, upper wire clip body 1 and drop wire clip body 2 is connected by being cased with the bearing pin 16 of torsion spring 15, upper wire clip body
1 and the opening of drop wire clip body 2 be defined as head end, the other end is then tail end, and opening is used for the clamping of wire.By torsion spring
15 divisions for driving upper wire clip body 1 and drop wire clip body 2.Diverter 3 is fixed on the head of upper wire clip body 1 by headless screw
End, is provided with cavity inside diverter 3, cavity is connected with the circular hole of its sidepiece, and limiting plate 10 is provided with cavity, covers on limiting plate 10
There is spring 19, limiting plate 10 is provided with one end of limiting plate draw ring 11 and stretches out from circular hole, and the top of diverter 3 offers through hole
14, through hole 14 is connected with cavity.
Rectangular slot 18 is symmetrically offered at the middle part of upper wire clip body 1 and drop wire clip body 2, springboard 4 is placed in logical
In groove 18, and its one end is made to be fixed on drop wire clip body 2 by resilient key 17, springboard 4 can be rotated along resilient key 17.In springboard
4 top offers L-type groove 22, and in the groove 18 of upper wire clip body 1 is provided with resilient key 17, makes springboard 4 in upright
During position, L-type groove 22 can be connected in 17 upper limit of resilient key.By limiting plate draw ring 11 and the top high-strength nylon of springboard 4
Rope 8 is attached, it is possible to use the pulling force of nylon rope 8 pulls limiting plate 10 to move back and forth.
The tail end of upper wire clip body 1 and drop wire clip body 2 respectively connects one piece of connecting plate 6, the company of making respectively with a resilient key 17
Plate 6 can be rotated along resilient key 17, and the other end in two pieces of connecting plates 6 passes through bearing pin 16 and 5 coaxial connection of arm-tie.Above-mentioned wire
The top that the matching used part of the one of pattern of earthing clamp also has latch 9, latch 9 is provided with latch ring 12, lower cylindrical
Body is provided with limited location snap ring, is provided with spring 13 in the bottom of latch 9.It is have insulating cord 7 on arm-tie 5, changes when needing to select
During to mode of operation, the other end of insulating cord 7 need to stretch out after being first fixed on latch ring 12 again.In drop wire clip body 2
Tail end bottom be fixed with hex bolts 20, the dead earth annealed copper wire 21 on hex bolts 20.
Wired earth wire clamp with said structure has two kinds of mode of operations, and one kind is commutating mode, another kind of right and wrong
Commutating mode.Wherein non-commutating mode is adopted immediately below cross-arm and when conductor spacing cross-arm is nearer suitable for earthing position.Make
With during the pattern ground connection operation, without using latch 9, directly insulating cord 7 can be lain on arm-tie 5, hand-held insulating cord 7 is in addition
One end, wire clamp is put down from directly over wire so as to which opening is directed at wire.When wire clamp distance of wire reaches certain distance,
Wire clamp is made to accelerate tenesmus, under the percussion of gravity, the L-type groove 22 on 4 top of springboard departs from from resilient key 17, upper wire clamp sheet
Body 1 and drop wire clip body 2 in the presence of arm-ties 5 and torsion spring 15, drive opening to open clamp wire, complete whole hanging wire and make
Industry.Wherein, arm-tie 5 and connecting plate 6 adopt coaxial connection, play a part of lever using its geometrical principle, make disassembling for wire clamp
Close more laborsaving and convenient.
When for big corner wire and conductor spacing cross-arm farther out, commutating mode can be selected, first by the one of insulating cord 7
End is lain on arm-tie 5, and middle part is fixed on latch draw ring 12, and other end is hand-held as operating side.Inserting for insulating cord 7 will be fastened
Insert in through hole 14 of the pin 9 from the top of diverter 3 in cavity, the limited location snap ring in the presence of limiting plate 10 to 9 bottom of latch
Carry out clamping locking.Because rope only transmits pulling force, the nylon rope 8 lain between springboard 4 and limiting plate draw ring 11 will not be to jumping
The blocking of plate 4 produces impact.Now, the L-type groove 22 on springboard 4 is just connected on resilient key 17.Staff is along horizontal
Wire clamp is put down line direction the outside for being placed in wire, and the operating side of hand-held insulating cord 7 moves closer to wire, in ground connection annealed copper wire
Under 21 action of gravity, naturally upward, without the need for additionally adjusting, and under gravity, insulating cord 7 is pulled the opening of wire clamp
Arm-tie 5, so that wire clip body opening opens clamps wire, now, springboard 4 is slid from resilient key 17, and springboard 4 is departing from
During limiting plate 10 is driven to the outside mobile of diverter 3 by nylon rope 8, lose locking of the limiting plate 10 to latch 9
Effect, latch 9 are ejected in the presence of spring 13 from diverter 3, complete the operation of whole hanging wire.
The wired earth wire clamp that this utility model is provided, using being flexibly connected, dismounting is very convenient for each several part, and operates
Simply, without the need for by experience control.With two kinds of hanging wire patterns can unrestricted choice, meet involved all at present production
The Grounding of aerial condutor.
Above example only to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art couple
Other modifications or equivalent that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope, all should cover in right of the present utility model.
