Embodiment
Hereinafter also describe the utility model in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.
As shown in Figure 1, according to embodiment of the present utility model, the temporary fastening device of this circuit, for interim hanging wire, comprises insulating pole 10 and fixture 20.Fixture 20 is fixedly installed on insulating pole 10, treats that hanging wire is hung on fixture 20.
Staff is in hanging wire, by the temporary fixed hanging wire for the treatment of of temporary fastening device of this circuit, and just can handle easily and treat that hanging wire carries out hanging wire work by insulating pole 10, make to need two people together the problems of the difficulty operation of hanging wire be resolved, staff can be sooner, better circuit is hung up properly.
In conjunction with shown in Figure 2, particularly, the fixture 20 of the temporary fastening device of this circuit comprises that the first fixed cover 21 and the second fixed cover 22, the second fixed covers 22 are fixedly attached to the first fixed cover 21, the first fixed covers 21 and are removably connected on insulating pole 10.By the different connection functions of two fixed covers, and utilize insulating pole 10, staff can more effectively manipulate and treat hanging wire, makes the process of hanging wire faster, facilitates.
Particularly, the second fixed cover 22 comprises the first half rings 221 and corresponding the second half rings 222 of the second half ring 222, the first half rings 221, and forms clamping space between the first half rings 221 and the second half rings 222.Preferably, clamping space is manhole.The clamping space that the first half rings 221 and the second half rings 222 form can will treat that hanging wire clamps, and makes to treat that hanging wire is not easy to drop effectively.In addition, clamping space is arranged to conglobate through hole, can fit with the external shape for the treatment of hanging wire better, effectively fixedly treat hanging wire.
Preferably, the first fixed cover 21 is annulus, and is set on insulating pole 10.Like this, the first fixed cover 21 of annulus can facilitate manufacturing, can also be effectively and mutually fastening between common insulating pole 10, and easy-to-operat.
Preferably, the first half rings 221 are fixedly connected on the first fixed cover 21, and the second half rings 222 are flexibly connected with the first half rings 221, and form hooping structure.The radially both sides of the first half rings 221 are provided with unthreaded hole, in unthreaded hole, be provided with rotationally threaded stem 223, the radially both sides of the second half rings 222 are provided with lug, and are provided with tapped through hole on lug, tapped through hole and threaded stem 223 screw-thread fit in the second half rings 222.Threaded stem 223 can freely rotate in unthreaded hole, due to the tapped through hole screw-thread fit in threaded stem 223 and the second half rings 222, when threaded stem 223 rotates, the tapped through hole in the second half rings 222 can be converted into rotatablely moving of threaded stem 223 straight line motion of the second half rings 222.Like this, between the first half rings 221 and the second half rings 222, form clamping space and just can regulate the size in space, adapt to treat better hanging wire.
In order better fixture 20 to be fixed on insulating pole 10, and can be according to operation site need to regulate the level altitude of fixture 20 on insulating pole 10, be disposed radially tapped hole at the first fixed cover 21, on the first fixed cover 21, be provided with hold out against insulating pole 10 hold out against screw 211.Staff holds out against screw 211 by tightening, and fixture 20 is fixed on insulating pole 10.In the time that staff need to regulate the height of fixture 20, staff will hold out against screw 211 and unscrew, and regulate the height of fixture 20, then will hold out against screw 211 and tighten, and fixture 20 can be fixed on insulating pole 10 again.Generally, the distance that arranges of fixture 20 is: staff's both hands are greater than 50CM apart from the distance of this device.
In order to protect better insulating pole 10 and to treat the isolation layer of hanging wire; on the surface of contact of fixture 20 and insulating pole 10 and/or with treat to be provided with protective layer 40 on the surface of contact of fixed line, protective layer 40 is protected insulating pole 10 surfaces and/or is treated that be not the fixed sharpened edge of device 20 of fixed line surface damages.
Preferably, in the present embodiment, adopt the mode of welding, the second fixed cover 22 is weldingly fixed on the first fixed cover 21.
From above description, can find out, the utility model the above embodiments have realized following technique effect: staff is in hanging wire, by the temporary fixed hanging wire for the treatment of of temporary fastening device of this circuit, make to need two people together the problems of the difficulty operation of hanging wire be resolved, staff can be sooner, better circuit is hung up properly.
