[0026] A plurality of positioning holes 9 are evenly formed on the first arc-shaped member 5 , a positioning pin 10 is provided on the first fixing member 3 , one end of the positioning pin 10 passes through the first fixing member 3 and the positioning hole 9 in sequence and extends to the outside of the first fixing member 3 , and a locking member 11 is threadedly connected to the positioning pin 10 .

[0027] like Figure 1The first fixing member 3 and the second fixing member 4 are respectively located on both sides of the holding pole 2 to facilitate the installation of the vacuum load switch body 1 on the holding pole. The first arc-shaped member 5 and the second arc-shaped member 6 can be combined into a complete ring. The vacuum load switch body 1 is an outdoor high-voltage vacuum load switch in the prior art. A pull ring is provided on the top of the positioning pin 10 to facilitate manual rotation of the positioning pin 10.

[0028] Both sides of the first fixing member 3 and the second fixing member 4 are fixedly connected with fixing blocks 12 , and fixing bolts 13 are provided on the fixing blocks 12 , and the fixing bolts 13 are used to fix the fixing blocks 12 together.

[0029] like Figure 2 The fixing blocks 12 are fixed together by fixing bolts 13 , and the first fixing member 3 and the second fixing member 4 can be fixed to both sides of the pole 2 .

[0030] Both ends of the first arc-shaped member 5 are provided with plugging grooves 14 , and both ends of the second arc-shaped member 6 are fixedly connected with plugging protrusions 15 used in conjunction with the plugging grooves 14 .

[0031] like Figure 5 The plug-in protrusion 15 is located in the plug-in groove 14, so that the first arc-shaped member 5 and the second arc-shaped member 6 are clamped together, which facilitates the movement of the first arc-shaped member 5 and the second arc-shaped member 6 inside the first fixing member 3 and the second fixing member 4.

[0032] One end of the support block 8 is fixedly connected to a mounting frame 16 , an insulating outer ring 17 is fixedly connected to the vacuum load switch body 1 and located inside the mounting frame 16 , and limiting members 18 are fixedly connected above and below the insulating outer ring 17 in the mounting frame 16 .

[0033] like Figure 3 The limiter 18 can prevent the insulating outer ring 17 and the vacuum load switch body 1 from moving up and down.

[0034] Two penetrating convex plates 19 are fixedly connected to the insulating outer ring 17 , and the two penetrating convex plates 19 are respectively located at the top and bottom of the supporting block 8 .

[0035] like Figure 2 and Figure 4 The two penetrating protrusions 19 both pass through the mounting frame 16 and extend to the top and bottom of the supporting block 8 respectively.

[0036] A connecting block 20 is fixedly connected to one side of the mounting frame 16, a pressure spring 21 is fixedly connected to the bottom of the connecting block 20, a clamping rod 22 is fixedly connected to the bottom of the pressure spring 21, and the bottom of the clamping rod 22 passes through the penetrating convex plate 19 and the supporting block 8 in sequence and extends to the outside of the penetrating convex plate 19.

[0037] like Figure 1 , Figure 2 and Figure 3 There are openings on the penetrating convex plate 19 and the supporting block 8 to facilitate the passage of the clamping rod 22. By lifting the clamping rod 22, the vacuum load switch body 1 can be pulled to the side away from the mounting frame 16 to remove the vacuum load switch body 1. Conversely, the vacuum load switch body 1 can be moved toward the mounting frame 16 to allow the penetrating convex plate 19 to pass through the mounting frame 16. Then the clamping rod 22 is released, and the pressure spring 21 presses the clamping rod 22 downward. The clamping rod 22 passes through the penetrating convex plate 19 and the supporting block 8, and the vacuum load switch body 1 is clamped and installed on the mounting frame 16.

[0038] The working principle of an outdoor high-voltage vacuum load switch provided by the utility model is as follows:

[0039] When the position of the vacuum load switch body 1 needs to be adjusted, the locking member 11 and the positioning pin 10 can be separated, and then the positioning pin 10 can be taken out upwards. At this time, the vacuum load switch body 1 can be rotated, and the support block 8 drives the first arc-shaped member 5 and the second arc-shaped member 6 to rotate inside the first fixing member 3 and the second fixing member 4 to adjust the position of the vacuum load switch body 1;

[0040] Then, the positioning pin 10 can be passed through different positioning holes 9 and the first fixing member 3, and then threadedly connected to the locking member 11 to position the first arc-shaped member 5, so that the first arc-shaped member 5 and the second arc-shaped member 6 cannot rotate, and the vacuum load switch body 1 cannot rotate either, thereby completing the positioning of the vacuum load switch body 1 after the adjusted position.

[0041] Compared with the related art, the outdoor high-voltage vacuum load switch provided by the utility model has the following beneficial effects:

[0042] The utility model provides rotatable first arc-shaped member 5 and second arc-shaped member 6 in first fixing member 3 and second fixing member 4, so that when taking out the positioning pin 10 upward, the vacuum load switch body 1 can be rotated, and the first arc-shaped member 5 and second arc-shaped member 6 are driven to rotate by the support block 8, so as to fine-tune the position of the vacuum load switch body 1. After the adjustment of the vacuum load switch body 1 is completed, the positioning pin 10 is passed through the first fixing member 3 and the first arc-shaped member 5 again to position the vacuum load switch body 1, so as to facilitate the adjustment of the position of the vacuum load switch body 1 and quickly connect the vacuum load switch with the external line, without repeatedly installing and disassembling the fixing device on the holding pole, and the operation is simple and convenient to use.
