It is shown in Figure 1, a kind of embodiments in accordance with the present invention, there is provided insulating bar, the insulation in the present embodiment
Action bars includes the body of rod 10 and lock 20, and the lock 20 is arranged on the end of the body of rod 10, and lock 20 includes upper jaw 21 and lower pincers
Mouth 22, upper jaw 21 and lower jaw 22 have the locked position for mutually fastening and the unlocked position being located remotely from each other.
Because the end of the insulating bar in the present embodiment is provided with lock 20, operated using the insulation in the present embodiment
During bar, such as during ground wire, by the effect of lock 20, can be by earth wire clamp snap ring locking in lock 20
It is interior, and upper jaw 21 and lower jaw 22 is mutually fastened during the locked position, upper act earth wire clamp snap ring, due to ground wire
Snap ring is locked between upper jaw 21 and lower jaw 22, it is ensured that ground eyelet does not fall off during extension is lifted.When by ground
Eyelet is supported to precalculated position so that in ground eyelet hooking to predetermined structure, by lower drag link body 10, now ground wire
Snap ring applies upward power to upper jaw 21 so that upper jaw 21 and lower jaw 22 are located remotely from each other and are in the unlocked position.It can be seen that,
Insulating bar lock of the invention conveniently realizes opens voluntarily, has ensured that earth wire clamp snap ring will not be slided during connecing hanging ground-wire
Fall, be easy to site safety to operate, so as to avoid causing personnel's injury and the damage of electrical equipment, operating process to install reliable.
Lower jaw 22 in the present embodiment includes that linkage section 221 and first links up with section 222, linkage section 221 and the body of rod 10
End is docked, and is easy to be fixed on lower jaw 22 end of the body of rod 10, and the first hook section 222 is connected to the side wall of linkage section 221
On；One end away from the body of rod 10 of linkage section 221 is provided with the mounting hole 223 extended along the length direction of the body of rod 10, upper jaw
21 one end is arranged in mounting hole 223, and is slided up and down in mounting hole 223 so that upper jaw 21 and lower jaw 22 are in locking
Switch between position and unlocked position.
Lower jaw 22 includes that construction section 211 and second links up with section 212, and the first end of construction section 211 is plugged in mounting hole 223
Interior, the second hook section 212 is connected with the second end of construction section 211 and is correspondingly arranged with the first hook section 222.
The structure of section 212 is linked up with by the first hook section 222 and second, lock can be in upper jaw 21 and lower jaw 22
Closure is a loop configuration for closing when tight position, and then ground eyelet is fixed on lock 20, prevents ground line card
Ring slides out from lock 20.During use, after ground eyelet is supported into precalculated position tangling, the body of rod is pulled downward on
10, now, ground eyelet applies the effect of upward power to the second hook section 212 so that construction section 211 is in mounting hole 223
Upward sliding, upper jaw 21 is pulled upwardly, and then the first hook hook section 212 of section 222 and second is located remotely from each other and is in
Unlocked position so that ground eyelet is skidded off from lock 20, is easy to move and remove insulating bar.
In order to ensure the structural stability of lock 20, the insulating bar in the present embodiment also includes positioning component 30, should
Positioning component 30 is used to be limited to construction section 211 in mounting hole 223.
Preferably, the positioning component 30 in the present embodiment includes locating slot 31 and keeper 32, and locating slot 31 is arranged on peace
Fill on the lateral wall of section 211, keeper 32 is fixedly mounted on linkage section 221, and upper jaw 21 and lower jaw 22 are in locking position
Put when switch and unlocked position between, keeper 32 the length direction of locating slot 31 reciprocatingly slide carry out it is spacing.
In other embodiments of the invention, positioning component 30 can also be set to the structure that chute adds projection, if
When putting, chute can be set in the outer wall one of both of the inwall of mounting hole 223 and construction section 211, and set in a further structurally
Projection is equipped with, as long as other modes of texturing under design of the invention, within protection scope of the present invention.
Preferably, the keeper 32 in the present embodiment is alignment pin, and simple structure is easy to processing.
It is highly preferred that alignment pin could be arranged to one, it is also possible to be set to multiple, such as two, when alignment pin is many
When individual, multiple alignment pins are arranged along the length direction of locating slot 31, when construction section 211 is moved up and down in mounting hole 223 pair
Upper jaw 21 carries out spacing.
Further in conjunction with shown in Fig. 1, the lock 20 in the present embodiment also includes locked component 23, and the locked component 23 is arranged on
So that upper jaw 21 and lower jaw 22 switch between locked position and unlocked position between upper jaw 21 and lower jaw 22.
Specifically, the locked component 23 in the present embodiment includes kicker magnet 231 and energy-stored spring 232.Wherein, kicker magnet
231 bottoms for being arranged on mounting hole 223；Energy-stored spring 232 is set on construction section 211, and the two ends of energy-stored spring 232 are distinguished
It is connected on the top of linkage section 221 and the second hook section 212.Preferably, kicker magnet 231 is strong magnet, and strong magnet is at least
One piece.
After ground eyelet is supported into precalculated position tangling, the body of rod 10 is pulled downward on, now, ground eyelet is hung to second
Hook section 212 applies the effect of upward power and the elastic force for cooperateing with energy-stored spring 232 so that construction section 211 in mounting hole 223 to
Upper slip, upper jaw 21 is pulled upwardly, and then the hook section 212 of the first hook section 222 and second is located remotely from each other and is in solution
Lock position so that after ground eyelet is skidded off from lock 20, the effect by kicker magnet 231 to the applying power of construction section 211 makes peace
Dress section 211 is moved downward, and then causes that whole upper jaw 21 is moved with locking state to the direction near lower jaw 22.
It can be seen that, during insulating bar use of the invention, the upper jaw of insulating bar lock 20 is pulled open upwards
21, earth wire clamp snap ring is put into jaw, because there is two pieces of kicker magnet suction, pressing upper jaw 21 can make upper jaw 21 and lower jaw
22 closures, during upper act, because ground eyelet is in the jaw of closing, and lower jaw 22 is to fix one with insulating bar
Body, ground wire weight is pressed in lower jaw 22, has ensured that ground wire does not fall off during lifting extension.After ground wire is hung up, now
In the upper jaw 21 of insulating bar, because there is energy-stored spring 232, when winning insulating bar downwards, upper jaw 21 can be borrowed line tweezer snap ring
Help energy-stored spring 232 to open, after extracing ground eyelet, remove insulating bar, the used hook being arranged on the side wall of the body of rod 10
The effect of structure 40, can auxiliary operation use.
As can be seen from the above description, the above embodiments of the present invention realize following technique effect：
Insulating bar of the invention uses spring and kicker magnet mechanism, closing jaw of the ground eyelet in kicker magnet adhesive
Do not fall off, upper jaw is solved because operating personnel does not tense firmly by spring meeting opens voluntarily when extracing ground eyelet
Ground wire, the problem that earth wire clamp snap ring is easily slid by insulative head provides safety guarantee to the personnel below operation area and equipment.
The preferred embodiments of the present invention are the foregoing is only, is not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
