[0025] An outdoor vacuum circuit breaker mounting base includes a circuit breaker body 1 and a mounting assembly. The mounting assembly includes a mounting plate 2, which is disposed on the lower surface of the circuit breaker body 1.

[0026] A pair of limit blocks 3 are fixedly installed on the upper surface of the mounting plate 2. A pair of limit grooves 4 are opened on the lower surface of the circuit breaker body 1. The upper ends of the pair of limit blocks 3 are respectively slidably installed inside the pair of limit grooves 4. Control blocks 5 are fixedly installed at both ends of the mounting plate 2. Rotating shafts 6 are rotatably installed on the inner side of the two control blocks 5. Rotating plates 7 are fixedly installed on the outer surface of the two rotating shafts 6. The two rotating plates 7 are respectively rotatably installed on the inner side of the two control blocks 5.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The limiting block 3 is slid into the limiting groove 4, so that the mounting plate 2 is placed on the lower surface of the circuit breaker body 1, and the rotating plate 7 is driven to rotate inside the control block 5 by the rotating shaft 6.

[0028] The lower ends of the two rotating plates 7 are provided with sliding grooves 8, and sliding blocks 9 are slidably arranged inside the two sliding grooves 8. A connecting block 10 is fixedly arranged at one end of each of the two sliding blocks 9.

[0029] like Figure 3 and Figure 5 When the connecting block 10 moves, the sliding block 9 slides inside the sliding groove 8, controlling the position between the rotating plate 7 and the connecting block 10.

[0030] Both connecting blocks 10 have threaded rods 11 slidably installed inside them. The lower ends of both threaded rods 11 are fixedly provided with torsion blocks 12, and the upper ends of both threaded rods 11 are threadedly provided with positioning blocks 13.

[0031] like Figure 5 When the threaded rod 11 is pushed to the outer surface of the positioning block 13, the rotating torsion block 12 causes the threaded rod 11 to be threaded into the interior of the positioning block 13.

[0032] Two positioning blocks 13 are fixedly installed at both ends of the circuit breaker body 1, and rectangular holes 14 are opened at the upper ends of the two rotating plates 7. The two positioning blocks 13 are respectively installed inside the two rectangular holes 14.

[0033] like Figure 2 and Figure 3 The positioning block 13 and the threaded rod 11 cooperate to make the positioning block 13 set inside the rectangular hole 14 at the upper end of the rotating plate 7, and fix the two rotating plates 7 to the two ends of the circuit breaker body 1 respectively.

[0034] The mounting plate 2 has a placement groove 15 on its lower surface, and a pair of arc-shaped blocks 16 are fixedly installed on the lower surface of the mounting plate 2. The interior of each pair of arc-shaped blocks 16 is threaded with mounting bolts 17.

[0035] like Figure 4 A placement groove 15 is made on the lower surface of the mounting plate 2, and the upper end of the column is placed inside the placement groove 15, so that a pair of arc-shaped blocks 16 are placed on the outer surface of the column. One end of two mounting bolts 17 is threaded into the pair of arc-shaped blocks 16 and the inside of the column, and the mounting plate 2 is fixed to the upper end of the column.

[0039] Place the mounting plate 2 on the upper end of the column, so that the upper end of the column is placed inside the placement groove 15. Insert the two mounting bolts 17 into the two arc-shaped blocks 16 and the inside of the column respectively, and fix the mounting plate 2 on the upper end of the column. Slide the circuit breaker body 1 on the upper surface of the mounting plate 2, so that the limiting block 3 slides inside the limiting groove 4. Rotate the two rotating plates 7 so that the two rotating plates 7 are placed vertically at both ends of the circuit breaker body 1, so that the two positioning blocks 13 are placed inside the two rectangular holes 14 respectively. Rotate the two torsion blocks 12 so that the two threaded rods 11 are threaded into the inside of the two positioning blocks 13 respectively. When the two threaded rods 11 move, they drive the sliding block 9 to slide inside the sliding groove 8. Through the cooperation of the threaded rods 11 and the positioning blocks 13, the two rotating plates 7 are fixed at both ends of the circuit breaker body 1, and the position between the mounting plate 2 and the circuit breaker body 1 is fixed.

[0040] Compared with related technologies, the outdoor vacuum circuit breaker mounting base provided by this utility model has the following advantages:
