[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model provides Figure 1-3 The self-locking structure shown in the figure fixes the overhead wire on the insulator, and an overhead wire installation groove 2 is set at the top of the insulator body 1 for fixing the wire, including a wire limiter 3, a right ring member 5 and a fixing member 8. The notch direction of the overhead wire installation groove 2 is flush with the notch direction of the wire limiter 3 and the wire limiter 2 11 in the initial state. The wire limiter 3 is rotatably connected to the No. 1 rotating rod 4, and the No. 1 rotating rod 4 is fixedly connected to the right ring member 5. A telescopic rod 7 is connected between the right ring member 5 and the fixing member 8, and a bolt fixing groove 6 is welded to the open end of the right ring member 5.

[0024] The entire insulator body 1 can conveniently and quickly fix the wire in the overhead wire installation groove 2 and the wire limiter 3 when used outdoors. The telescopic rod 7 can be used to extend the distance of the right annular member 5 and the fixing member 8, so as to better use the insulator bodies 1 of various diameters.

[0025] The fixing part 8 is connected to the left ring part 9 through the telescopic rod 7. The left ring part 9 is provided with a socket 12, and the socket 12 is connected to the umbrella-shaped telescopic part 13. The second rotating rod 10 can be inserted into the socket 12. The second rotating rod 10 is rotatably connected to the wire limiting part 2 11. The size and shape of the wire limiting part 2 11 are the same as those of the wire limiting part 1 3. The expandable end of the umbrella-shaped telescopic part 13 contacts the sliding gasket 14. The sliding gasket 14 can be slidably connected to the axis of the umbrella-shaped telescopic part 13, and its axis is fixedly connected to the bottom of the second rotating rod 10.

[0026] The entire space for placing the wires is enlarged by the umbrella-shaped telescopic member 13 that can be pulled out of the insertion hole 12, so that wires with larger diameters can be placed, and the scope of use is expanded.

[0027] The left annular member 9 and the right annular member 5 are arranged in mirror symmetry with respect to the fixing member 8, and bolt fixing grooves 6 are welded on the left annular member 9 and the right annular member 5, bolts can be connected between the two bolt fixing grooves 6, and threaded holes 15 are provided on the left annular member 9 and the right annular member 5, and the positions of the threaded holes 15 correspond to the positions of the No. 1 rotating rod 4 and the No. 2 rotating rod 10 respectively.

[0028] The left annular member 9 and the right annular member 5 can be relatively spaced apart, which can better adapt to the use of the insulator body 1 with a large diameter, and can also facilitate rapid installation and sleeve installation on the insulator body 1.

[0029] Working principle of this utility model:

[0030] Refer to the instruction manual Figure 1-3 When using the utility model, first, when the insulator body 1 needs to be used outdoors, the overhead wire installation groove 2 is used to clamp the wire (the prior art may use iron wire to wrap the wire and the overhead wire installation groove 2 to fix them), first pull the right ring member 5 and the left ring member 9 away from the fixing member 8, the telescopic rod 7 is stretched, and the right ring member 5 and the left ring member 9 can be separated to a distance suitable for the diameter of the insulator body 1, and then they are sleeved on the insulator body 1;

[0031] Refer to the instruction manual Figure 3-5 When using the utility model, after the sleeve is set, the bolts can be used to align the positions of the two bolt fixing grooves 6 to fix them, and the wires are placed in the wire limiter 1 3 and the wire limiter 2 11 in sequence (when the wires are not placed, they can be rotated to open, and after the placement is completed, they can be rotated to the position corresponding to the threaded hole 15), and the bolts are inserted into the threaded hole 15 to fix the wires;

[0032] If the diameter of the wire is large, the second rotating rod 10 and the first rotating rod 4 can be pulled upwards, and the umbrella-shaped telescopic member 13 can be pulled out from the insertion hole 12, so that the positions of the first rotating rod 4 and the second rotating rod 10 are raised to better adapt to the large diameter wire.
