In the figures 1-2, 1 represents an insulating shell, 2 represents a turbine spring, 3 represents a rotating handle, 4 represents a current test line, 5 represents a voltage test line, 6 represents a magnetic suction piece, 7 represents a hook, 8 represents a buckle belt capable of fixing an insulating adhesive tape, 9 represents a buckle belt capable of fixing a wire stripper and 10 represents a buckle belt capable of fixing a screwdriver.
Detailed Description
The technical solutions in the embodiments of the present invention will be described, clearly and completely, and the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments, in the accompanying drawings of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1-2, the utility model relates to a but extension-type positioning's relay protection appearance testing line device, including insulating casing 1, turbine spring 2, current test line 4 and voltage test line 5.
The current test wire 4 and the voltage test wire 5 are contracted in the insulating shell 1 through the turbine spring 2, and the ends of the current test wire 4 and the voltage test wire 5 are exposed out of the wire outlet of the insulating shell 1. And magnetic attraction pieces 6 which are matched with each other to position the pull-out lengths of the current test wire 4 and the voltage test wire 5 are arranged at the outlet of the insulating shell 1 and on the current test wire 4 and the voltage test wire 5.
When the device is used, the current test wire 4 or the voltage test wire 5 is pulled out from the outlet of the insulating shell 1, and when the magnetic attraction piece 6 on the current test wire 4 or the voltage test wire 5 is in contact with the magnetic attraction piece 6 at the outlet of the insulating shell 1, the magnetic attraction pieces 6 attract each other to realize positioning and pulling-out length. When the pulling force is greater than the attraction force between the magnetic attraction pieces 6, the current test wire 4 or the voltage test wire 5 can be continuously drawn out. After the use, drive turbine spring 2 through wrench movement twist the twist grip 3 and accomodate current test line 4 or voltage test line 5. It should be noted that the utility model discloses a magnetic force that adopts inhales piece 6, its suction is greater than the shrink power of turbine spring 2 self, need just can realize the shrink function to current test line 4 or voltage test line 5 through the shrink power of twisting twist rotary handle 3 and increase turbine spring 2.
In order to facilitate an operator to observe the drawn length of the current test wire 4 or the voltage test wire 5 at any time, length scale values are further arranged on the outer surfaces of the current test wire 4 and the voltage test wire 5.
In addition, in order to further satisfy the operation convenience of the operator, a hook 7 may be additionally provided to the insulating housing 1. A buckle belt 8 capable of fixing an insulating adhesive tape, a buckle belt 9 capable of fixing a wire stripper and a buckle belt 10 capable of fixing a screwdriver can be additionally arranged on the outer surface of the insulating shell 1. The hook 7 is used for hanging the test line device on clothes of an operator or other equipment, and the various buckle belts are convenient for the operator to take out and store other tools quickly.
