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 lead.
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 lead.
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 lead " 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 this utility model earth lead:
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 lead, 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 earth lead of the present utility model is pressed from both sides movable part 2, alignment
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
Wire pressing from both sides movable part 2 tap and need to hang wire, now, it is clamping that wire folder movable part 2 can back through wire
The hollow space of locking member 1, returns to start bit, and relies on inertia by outer lateral deviation tooth and lower end after rotating 360 degrees
Solely tooth occlusion, now wire folder medial shell reed 4 is through crimp firm grip wire, completes handcuffss type and connects
The installation of ground wire.
Handcuff-type anti-fall grounding wire of the present utility model, operating personnel is in operation process, and earth lead is firm
Be connected on dead line so that earth lead does not comes off in the case of false touch is touched by mistake and blown and is easy to
Dismounting, and safe and reliable.
