[0020] See also Figure 1-4The utility model provides a technical solution: an assembly structure of a circuit breaker, including a leakage circuit breaker body 1, an air-open circuit breaker body 2 is arranged on the left side of the leakage circuit breaker body 1, a T-shaped block 3 is fixedly connected to the right wall of the air-open circuit breaker body 2 near the bottom, a groove matching the T-shaped block 3 is opened near the bottom of the left wall of the leakage circuit breaker body 1, a T-shaped groove matching the T-shaped block 3 is opened at the top of the inner cavity of the groove, the inner wall of the T-shaped groove and the surface of the T-shaped block 3 are polished, and the left wall of the leakage circuit breaker body 1 near the top is fixedly connected to the right wall of the air-open circuit breaker body 2 near the bottom. A movable groove is opened at the right side, and a card block 10 is movably connected in the movable groove. The bottom of the card block 10 is inclined near the left side. A limit hole is opened on the right wall of the card block 10. A spring 9 is fixedly connected to the inner wall on the left side of the limit hole. The right end of the spring 9 is fixedly connected to the limit rod 7, and the right end of the limit rod 7 is fixedly connected to the inner wall on the right side of the movable groove. The top and bottom of the limit rod 7 are fixedly connected to the limit block 8 near the left end, and the top and bottom of the inner cavity of the limit hole are opened with limit grooves matching the limit block 8. The right wall of the empty circuit breaker body 2 is opened. A card slot matching the card block 10 is provided, a through slot is provided at the top of the movable slot cavity, a moving block 4 is fixedly connected to the top of the card block 10, the front and rear walls of the moving block 4 near the left and right sides are movably connected with pulleys 6 through rotating shafts and bearings, and the front and rear inner walls of the through slot are provided with sliding slots matching the pulley 6, and the top of the moving block 4 passes through the moving slot and is fixedly connected with a push block 5, and a moving slot matching the push block 5 is provided at the top of the leakage circuit breaker body 1, and the top of the push block 5 near the left and right sides is an arc-shaped concave surface, and The inner walls of the arc-shaped concave surfaces are provided with anti-slip patterns. The T-shaped block 3 and the T-shaped slot can effectively ensure the stability of the horizontal connection between the leakage circuit breaker body 1 and the air-open circuit breaker body 2. At the same time, the setting of the clamping block 10 and the clamping slot ensures the stability of the vertical connection between the two. Through the mutual cooperation between the limit rod 7, the spring 9, the moving block 4 and the push block 5, the clamping block 10 can be displaced in the left and right directions, while keeping a tendency to move to the left, thereby ensuring the convenience of splicing and disassembly of the two.

[0021] Working principle: When using this technical solution, align the T-shaped block 3 on the right side of the air-disconnected circuit breaker body 2 with the groove on the left side of the leakage circuit breaker body 1, and push it upward so that the T-shaped block 3 is stuck in the slot. During its upward movement, when the top of the air-disconnected circuit breaker body 2 contacts the bottom of the block 10, the block 10 will be pushed to move to the right and retract into the movable slot, and the spring 9 will be compressed. When the slot is aligned with the block 10, the spring 9 stretches and moves the block 10 to be stuck in the slot, thereby realizing convenient splicing between the leakage circuit breaker body 1 and the air-disconnected circuit breaker body 2. When disassembly is required, push the push block 5 to move to the right. Through the setting of the pulley 6, the movement of the push block 5, the movable block 4 and the block 10 is smoother. When the left side of the block 10 is out of the slot, the disassembly between the two can be realized.
