Bar 14 is positioned at below wire folder base 8, and is connected with wire folder base 8, and the top of insulating bar 14 is arranged
The brim of a hat 12, insulating bar 14 sidepiece is had to be provided with the steel ball coordinated with positioning hole groove；The described the brim of a hat 12 top sets
It is equipped with arc ramp 11.
The profile of tooth of described zigzag structure is equilateral triangle.
Described screw 9 is fine thread cross screw.
For convenience of description, the outside of described wire folder movable part 2 is set to zigzag structure, zigzag structure
Tooth hereinafter referred to as partially, only tooth jump ring lever one end is toothed projections structure, and toothed projections structure is the most only
Tooth.
Below in conjunction with concrete each parts of handcuff-type anti-fall grounding wire and the performance of each parts to handcuff-type anticreep
The earth connection that falls is described further:
The clamping locking member of wire 1: during installing ground wire, play used by fixed insulation bar 14.
Wire folder movable part 2: using inclined tooth to design outside it, profile of tooth is equilateral triangle, when installing earth connection,
Tooth partially is engaged with only tooth jump ring lever 5 of lower end, plays the effect of dead earth line difficult drop-off.
Connecting shaft 3: be used for connecting the clamping locking member of wire 1 and wire folder movable part 2, make wire clamp movable part 2 energy
Enough flexible 360 degree of rotations.
Spring leaf 4: quantity is two, is respectively installed in the clamping locking member of wire 1 and wire folder movable part 2, in
Outer arc symmetric form, can be made conductor clamping by the elasticity of spring leaf 4 and be fixed during installation, passing through during dismounting
The elasticity of spring leaf 4 can make wire folder movable part 2 be more easy to flick.
Solely tooth jump ring lever 5: solely this part of tooth jump ring lever 5 designs only tooth is leading role, only tooth and wire folder
Being fixed on by wire when tooth is interlocked partially in wire folder, when the inclined tooth of wire folder separates with only tooth, wire takes off
From, only tooth is stretched by the contracting of spring 7 with being engaged of inclined tooth, and it is by rotating insulated bar 14 that only tooth departs from inclined tooth.
During rotating insulated bar 14, only tooth end is gradually increasing along the arc ramp 11 of insulating bar 14 upper end, the most solely
Tooth compression spring 7 declines to depart from inclined tooth dismantles earth connection.
Fixing bar 6: be used for fixing only tooth jump ring lever 5 and playing point action so that solely tooth jump ring lever 5
Can flexible rotating.
Spring 7: elastic by spring 7, plays the only tooth jump ring lever 5 of reset and acts on.
Wire folder base 8: be connected with insulating bar 14 within connecting sleeve pipe 10 for encapsulation.
Screw 9: use fine thread cross screw, is used for fixing wire folder base 8 within connecting sleeve pipe 10.
Connect sleeve pipe 10: for connecting the intervening components of wire folder and insulating bar 14, and by screw 9 and cap
It is firm that eaves 12 design makes wire folder part be connected with insulating bar 14.
Arc ramp 11: using arc ramp 11 to design on the insulating bar 14 top the brim of a hat 12, it is mainly made
Arc ramp 11 can be made to rotate with when being and rotate insulating bar 14, the only tooth opposite end of jack-up only tooth jump ring lever 5,
The inclined tooth making only tooth fall with wire folder movable part 2 departs from, it is achieved " unblock " function during dismounting earth connection.
The brim of a hat 12: insulating bar 14 upper end uses the brim of a hat 12 to design, in order to insulating bar 14 upper end is stuck in adapter sleeve
In pipe 10, the brim of a hat 12 upper end is symmetrical arc ramp 11, is also that dismounting earth connection " switchs ".
Rotate jump ring 13: for preventing insulating bar 14 from arbitrarily rotating, by insulating bar 14 He within connecting sleeve pipe 10
Connect sleeve pipe 10 and be designed to umbrella use steel ball and the principle of hole jump ring, insulating bar 14 is inlayed with steel ball,
Steel ball card prevents from arbitrarily rotating at the positioning hole groove connecting sleeve pipe 10, but rotating mode controls insulation
The rotation of bar 14, here it is " the unlocking design " of insulating bar 14.
Insulating bar 14: the band the brim of a hat 12 that is mainly characterized by of insulating bar 14 designs with band " unblock ".
The concrete assemble method of each parts of handcuff-type anti-fall grounding wire is as follows:
1, insulating bar 14 is inserted in connection sleeve pipe 10, makes the top the brim of a hat 12 of insulating bar 14 just block
Connecting the internal diameter thickness intersection of sleeve pipe 10, now, alignment is connected by the steel ball that insulating bar 14 sidepiece is arranged
Hole slot position inside sleeve pipe 10, and in positioning hole groove, it is provided with rotation jump ring 13, complete insulating bar 14
Top and the installation being connected sleeve pipe 10, and can guarantee that insulating bar 14 flexible rotating within connecting sleeve pipe 10.
2, handcuffss type wire folder base 8 is inserted in connection sleeve pipe 10, makes wire folder base 8 and insulating bar
14 tops link together within connecting sleeve pipe 10, make the arc ramp 11 at insulating bar 14 top be directed at only tooth
The end of jump ring lever 5, it is ensured that arc ramp 11 jack-up only tooth jump ring thick stick can be triggered when rotating insulating bar 14
Bar 5 makes only tooth depart from inclined tooth, it is achieved " dropout " operates, and finally installs the fixed screw connecting sleeve pipe 10
9, wire is pressed from both sides base 8 and is fixed in connection sleeve pipe 10, complete the complete of ground wire guide clamp and insulating bar 14
Portion installs, and can guarantee that insulating bar 14 flexible rotating within connecting sleeve pipe 10.
Now according to the situation in routine work, introduce the using method of earth connection of the present invention:
1, necessary first electrical verification before hanging earthing conductor, after determining the true no-voltage of cable, proceeds by hanging earthing conductor.
2, first, pass through to be connected with insulating bar 14 part by this earthing clamp line end according to above-mentioned installation method
Sleeve pipe 10 is reliably connected, it is ensured that possess good conductive effect.
3, when carrying out mounting earth connection, should first connect earth terminal, and determine can be big by means of terrain Quick dredging accident
Electric current, it is ensured that ground connection quality.
4, after earth terminal is installed, the handcuffss type wire of the earth connection of the present invention is pressed from both sides movable part 2, be directed at without
The wire of electricity so that it is become 90 degree of right angles to carry out clamping with wire, insulating bar 14 of with the hands holding with a firm grip, firmly will lead
Wire clamp movable part 2 taps need to hang wire, and now, wire folder movable part 2 can back through the clamping locking member of wire 1
Hollow space, return to start bit after rotating 360 degrees, and rely on inertia to be stung by only with lower end for outer lateral deviation tooth tooth
Closing, now wire folder medial shell reed 4 is through crimp firm grip wire, completes handcuffss type earth connection
Install.
The handcuff-type anti-fall grounding wire of the present invention, operating personnel is in operation process, and earth connection firmly connects
It is connected on dead line so that earth connection does not comes off and readily accessible in the case of false touch is touched by mistake and blown,
And it is safe and reliable.
