The first diagonal bar 3 and the second diagonal bar 4 are rotatably connected to the second angle steel 102, and the first diagonal bar 3 and the second diagonal bar 4 are located on the sides of the two support crossbars 2 away from each other.

[0026] A movable installation groove 5 is provided on the support crossbar 2. A fixed bolt 6 is provided on the first diagonal bar 3. One end of the fixed bolt 6 sequentially penetrates through the first diagonal bar 3, the movable installation groove 5, the second diagonal bar 4 and is threadedly connected to a fixed nut 7. An anti-slip gasket 8 is sleeved on the outer surface of the fixed bolt 6, and the anti-slip gasket 8 is arranged between the fixed nut 7 and the second diagonal bar 4. A positioning component for restricting the movement of the fixed nut 7 is provided on one side of the second diagonal bar 4.

[0027] As Figure 4 and Figure 5, one end of the fixing bolt 6 is fixedly connected to a regular hexagon-shaped bolt cap 601, and a limiting angle plate 602 is fixedly connected to one side of the first diagonal rod 3. The limiting angle plate 602 fits against one side of the bolt cap 601, which can limit the rotation of the bolt cap 601 and the fixing bolt 6;

[0028] Such as Figure 2 and Figure 3 , the anti-slip gasket 8 can provide anti-slip protection between the fixing nut 7 and the second diagonal rod 4, and the tension spring 16 has a thrust force on the sliding connecting plate 17 and the limiting block 18 in the direction of the fixing bolt 6.

[0029] A U-shaped fixing rod 9 is arranged on one side of the first angle steel 101. Both ends of the U-shaped fixing rod 9 penetrate through the first angle steel 101 and are threadedly connected with mounting nuts 10.

[0030] Such as Figure 1 and Figure 2 , by using the threaded connection of the mounting nut 10 and the U-shaped fixing rod 9, the first angle steel 101 can be locked on one side of the holding pole 1. Similarly, the second angle steel 102 can be locked on the holding pole 1.

[0031] A fixing notch 11 is formed on the bracket cross bar 2. The fixing notch 11 is used to assist in the installation of the outdoor vacuum circuit breaker. A reinforcing block 12 is fixedly connected between the two bracket cross bars 2.

[0032] Such as Figure 1 , the two bracket cross bars 2 are connected together by the reinforcing block 12 to improve the stability of the bracket cross bar 2. The outdoor vacuum circuit breaker can be fixed to the top of the bracket cross bar 2 by bolts passing through the fixing notch 11, and the bracket cross bar 2 provides support for the outdoor vacuum circuit breaker.

[0033] Two protruding blocks 13 are fixedly connected to the second angle steel 102. A rotating shaft 14 is rotatably connected between the two protruding blocks 13. One end of each of the first diagonal rod 3 and the second diagonal rod 4 is fixedly connected to the rotating shaft 14 to achieve the rotational connection with the second angle steel 102.

[0034] Such as Figure 1 , the rotating shaft 14 is rotatably connected to the protruding block 13, and the protruding block 13 is fixed on the second angle steel 102, so that the first diagonal rod 3 and the second diagonal rod 4 can rotate synchronously on the second angle steel 102 through the rotating shaft 14.

[0035] The positioning assembly includes a positioning sleeve 15 fixed to one side of the first diagonal rod 3. A tension spring 16 is fixedly connected inside the positioning sleeve 15. One end of the tension spring 16 is fixedly connected to a sliding connecting plate 17. A limiting block 18 is fixedly connected to one side of the sliding connecting plate 17. An arc-shaped groove 19 is formed on one side of the limiting block 18.

[0036] Such as Figure 2 andFigure 3 The surface of the arc-shaped groove 19 is adapted to the surface of the fixing bolt 6, so that when the limiting block 18 moves, the fixing bolt 6 can be relatively fitted into the arc-shaped groove 19.

[0037] A first sliding groove 20 is formed on one side of the positioning sleeve 15. A sliding shaft 21 is fixedly connected to one side of the sliding connecting plate 17. The sliding shaft 21 is slidably connected to the first sliding groove 20. A second sliding groove 22 is formed on the limiting block 18. A limiting shaft 23 is fixedly connected to one side of the second inclined rod 4. The limiting shaft 23 is slidably connected to the second sliding groove 22.

[0038] Such as Figure 2 And Figure 3 By using the sliding connection between the sliding shaft 21 and the first sliding groove 20 and the sliding connection between the limiting shaft 23 and the second sliding groove 22, the sliding directions of the sliding connecting plate 17 and the limiting block 18 can be restricted.

[0039] The working principle of a single-pole bracket of an outdoor vacuum circuit breaker provided by the present utility model is as follows:

[0040] First, manually push the limiting block 18 towards the positioning sleeve 15, rotate the first inclined rod 3 and the second inclined rod 4 so that the first inclined rod 3 and the second inclined rod 4 move to both sides of the bracket cross bar 2, and then pass the fixing bolt 6 through two bracket cross bars 2 and the second inclined rod 4 from one side of the first inclined rod 3 and thread it with the fixing nut 7 to fix the first inclined rod 3, the second inclined rod 4 and the bracket cross bar 2;

[0041] Then release the limiting block 18, the tension spring 16 extends to push the sliding connecting plate 17, and the sliding connecting plate 17 drives the limiting block 18 to move to the side of the fixing nut 7 away from the bracket cross bar 2 to limit the fixing nut 7, so that the fixing nut 7 will not move, avoiding loosening between the fixing nut 7 and the fixing bolt 6.

[0042] Compared with the related art, a single-pole bracket of an outdoor vacuum circuit breaker provided by the present utility model has the following beneficial effects:

[0043] The present utility model provides support for the bracket cross bar 2 through the first inclined rod 3 and the second inclined rod 4, improves the stability and compressive capacity of the bracket cross bar 2, can provide more reliable support for the outdoor vacuum circuit breaker installed above, improves the horizontality of the bracket cross bar 2. At the same time, through the movable installation groove 5 provided on the bracket cross bar 2, the fixed positions of the first inclined rod 3 and the second inclined rod 4 on the bracket cross bar 2 can be adjusted, improving the flexibility of the connection between the first inclined rod 3, the second inclined rod 4 and the bracket cross bar 2, expanding the applicable range of the bracket. Furthermore, the limiting block 18 in the positioning component restricts the fixing nut 7 from one side, avoiding loosening of the fixing nut 7 and improving the connection stability between the first inclined rod 3, the second inclined rod 4 and the bracket cross bar 2.

[0044] The foregoing has shown and described the basic principles, main features and advantages of the present utility model.
