Specific embodiment
In order to preferably understand technical solution of the present invention, below by specifically embodiment and in conjunction with attached drawing
It is described in detail:
Fig. 1 to Fig. 5, a kind of low-voltage comprehensive distribution box segmented insulating bar of the invention are please referred to, including is located at behaviour
Make bar holding section 1, operating stick functional section 2 and tube-in-tube structure 3.
The top of operating stick holding section 1 and the tail portion of operating stick functional section 2 are respectively equipped with hickey, operating stick holding section
1 and operating stick functional section 2 be threadedly coupled the formation operation body of rod.The length of operating stick holding section 1 and operating stick functional section 2 is respectively
0.7m, length be suitable for, will not because be segmented it is too long not readily portable, will not because combination after length it is inadequate, can not touch liftoff
The distribution box of 2.5m or so switchs.The top of operating stick functional section 2 is equipped with work department 21.The side of work department 21 is equipped with sleeve set
Interface 22 cooperates with tube-in-tube structure 3, for plucking, hanging sleeve barrel structure 3；The other side of work department 21 is equipped with pull ring drag hook 23, uses
To catch on the pull ring 33 of tube-in-tube structure 3, switch switching on and off is realized.The middle part of operating stick functional section 2 is equipped with the double-deck umbrella rain protection knot
Structure 24.The bottom of operating stick holding section 1 is equipped with rubber grips handle 11, and the surface of glue grab handle, which is equipped with, increases protrusion of rubbing, convenient for operation
Personnel use.
Tube-in-tube structure 3 include with the matched low-voltage cabinet sleeve 31 of low-voltage cabinet crane head and with the matched behaviour of sleeve socket 22
Make rod sleeve 32, low-voltage cabinet sleeve 31 and operation rod sleeve 32 interconnect.In use, by 22 sets of sleeve socket in operating stick
On sleeve 32, tube-in-tube structure 3 to be moved and is arranged, the end face of operation rod sleeve 32 is equipped with a dropproof hoodle 35,
Tube-in-tube structure 3 is placed accidentally to fall.Set there are two pull ring 33 low-voltage cabinet sleeve 31 is monosymmetric, pull ring by linking arm 34 with
Low-voltage cabinet covers 32 connections.Square crane head running-on, a line and linking arm are offered on the end face of low-voltage cabinet sleeve 32
34 angle is a, a=70 degree.Such angle makes after tube-in-tube structure 3 is socketed in the crane head of low-voltage cabinet, pull ring 33
Shape has a certain degree, and is convenient for stress, and the easier operation pull ring of staff is enabled to carry out switching on and off operation.
A kind of low-voltage comprehensive distribution box segmented insulating bar moral of the invention uses step are as follows:
1) with the socket operation rod sleeve 32 of sleeve socket 22, low pressure is hung over by 31 sets of low-voltage cabinet sleeve of tube-in-tube structure 3
In the crane head of comprehensive distribution box；
2) sleeve socket 22 is deviate from from operation rod sleeve 32, is then hooked in the one of tube-in-tube structure 3 with pull ring drag hook 23
On layback ring 33；
3) insulating bar is pulled down, tube-in-tube structure 3 rotates, and power transformation box crane head drives case inner link to realize together with switch
