The outdoor high-voltage vacuum circuit breaker for safe hoisting includes: a mounting base 1, a circuit breaker 2 and two groups of circuit breakers 3 are mounted on the top of the mounting base 1, baffles 13 are fixedly mounted on the left and right side walls of the mounting base 1, and two groups of rectangular grooves 16 are opened on the left and right side walls of the mounting base 1 located below the two groups of baffles 13, and the rectangular grooves 16 pass through the bottom of the mounting base 1. The upper ends of the inner walls of the two groups of rectangular grooves 16 are fixedly mounted with rotating shafts 17, and the outer walls of the two groups of rotating shafts 17 are rotatably connected with handles 15. The left and right side walls of the mounting base 1 are installed with a plurality of A limit block 1 20 and a limit block 21 are formed, and the limit blocks 1 20 and the limit blocks 21 are respectively arranged on both sides of the rectangular groove 2, and the limit blocks 1 20 and the limit blocks 21 are internally plugged and connected with the limit plate 18, and the other end of the limit plate 18 is fixedly installed with a rectangular plate 14, and two groups of guide rods 22 are fixedly installed on the side wall of the rectangular plate 14, and the guide rods 22 pass through the limit block 21, and the guide rods 22 are slidably connected to the limit block 21, and a spring 19 is fixedly installed between the limit block 21 and the rectangular plate 14, and the spring 19 is sleeved on the outside of the guide rod 22.

[0021] The top of the mounting seat 1 is provided with two sets of rectangular grooves 5 , and a bidirectional threaded rod 9 is rotatably connected between the inner walls at the left and right ends of the mounting seat 1 .

[0022] The left and right ends of the bidirectional threaded rod 9 are both threadedly connected with threaded sleeves 7, and the tops of the two groups of threaded sleeves 7 are fixedly installed with rectangular blocks 8, and the tops of the two groups of rectangular blocks 8 are fixedly connected to the two groups of circuit breakers 2 3.

[0023] A folding plate 4 is fixedly installed between the side walls at the left and right ends of the two groups of rectangular blocks 8 and the inner wall of the rectangular groove 5. The folding plate 4 can be extended or compressed as the rectangular blocks 8 move.

[0024] A worm gear 12 is fixedly installed in the middle of the bidirectional threaded rod 9, and a rotating shaft 10 is rotatably connected to the front and rear ends of the inner wall of the mounting seat 1. A worm 11 is fixedly installed in the middle of the rotating shaft 10, and the worm 11 is meshed with the worm gear 12.

[0025] One end of the rotating shaft 10 passes through the outside of the mounting base 1, and the rotating shaft 10 located outside the mounting base 1 is fixedly installed with a round block 6.

When the limit plate 18 leaves the upper part of the rectangular groove 2 16, the handle 15 is rotated from the bottom of the mounting seat 1 to the side of the mounting seat 1, and the rectangular plate 14 is released. The limit plate 18 will automatically reset along the guide rod 22. Then, after the rope is connected to the handle 15, the mounting seat 1 is hoisted as a whole to the installation position. When the handle 15 is not needed, it can be rotated to the inside of the rectangular groove 2 16.

[0027] Compared with the related art, the outdoor high-voltage vacuum circuit breaker provided by the utility model that is easy to safely hoist has the following beneficial effects:

[0028] Through the interaction of components such as the rectangular groove 16 and the rotating shaft 17, the handle 15 can be placed inside the rectangular groove 16 when not in use, to prevent the handle 15 from being exposed to the outside for a long time and being corroded, which would bring danger to the lifting work. Through the interaction of components such as the rectangular plate 14, the limit plate 18, the limit block 20, the spring 19 and the guide rod 22, the handle 15 can be confined inside the rectangular groove 16 and can be quickly taken out when needed.
