[0023] In the structure, the opening and closing mechanism of the device is controlled by the operating handle 3. When the operating handle 3 is operated by the staff, the rotating action of the operating handle 3 will cause the operating structure 9 and the rotating rod 12 to rotate synchronously on the inner side wall of the circuit breaker body 1. During the rotation, the movement of the rotating rod 12 will drive the operating structure 9 to lock the clamping structure 11, thereby stabilizing the position of the operating handle 3 and the operating structure 9. In addition, the rotation of the operating structure 9 will also cause the moving contact 13 to move towards the outer wall of the static contact 16. When the moving contact 13 touches the outer wall of the static contact 16, the device is activated. At the same time, the device is equipped with a double contact system, which is designed to immediately cut off the circuit when the circuit encounters overload or short circuit and other abnormal conditions, effectively protecting the circuit from damage. The double contact design not only enhances the stability of the contact, but also prolongs the service life of the device and significantly reduces the probability of failure caused by poor contact.
[0024] In a preferred embodiment: the inner wall of the connecting block 4 is fixedly provided with a limiting rod 7, the outer wall of the limiting rod 7 is provided with a limiting groove 17, the outer wall of the connecting block 2 is provided with a placing groove 8, and one end of the spring 19 is fixedly provided on the inner wall of the placing groove 8, and the other end of the spring 19 is fixedly provided with a pressing block 18.
[0025] In the structure, during the operation of connecting the circuit breaker body 1 and the circuit breaker body 2, the limiting rod 7 is first accurately guided to the inner wall area of the placing groove 8, and the limiting rod 7 is used to limit the pressing block 18. This causes the pressing block 18 to drive the spring 19 to displace along the inner wall of the placing groove 8 under the action of pressure. When the limiting rod 7 is completely embedded in the inner wall of the placing groove 8, the specific mechanism of the limiting groove 17 triggers the release of the elastic potential energy accumulated in the spring 19. Then, the released energy of the spring 19 drives the pressing block 18 to move towards the inner wall of the limiting groove 17, finally ensuring that the limiting rod 7 is stably fixed in the inner wall of the placing groove 8, thereby successfully achieving the effective connection of the circuit breaker body 1 and the circuit breaker body 2.
[0026] In a preferred embodiment: the pressing block 18 is matched with the inner wall of the limiting groove 17, and the clamping block 10 is clamped with the inner wall of the clamping structure 11.
[0027] In the structure, the pressing block 18 is matched with the inner wall of the limiting groove 17 to limit the limiting groove 17, so that the limiting rod 7 is fixed in the inner wall of the placing groove 8. The clamping block 10 is clamped with the clamping structure 11 to limit the operating handle 3 and the operating structure 9.
[0028] In a preferred embodiment: the operating handle 3 is clamped with the outer wall of the operating structure 9, and the limiting rod 7 is matched with the inner wall of the placing groove 8.
[0029] In the above structure, the control handle 3 is connected with the control structure 9 through clamping, so that the control handle 3 drives the control structure 9 and the rotating rod 12 to rotate when the control handle 3 rotates, and the control handle 3 will not be stuck when the limiting rod 7 moves to the inner wall of the placing groove 8.
[0030] In a preferred embodiment, the clamping block 10 and the clamping structure 11 are made of rubber, and the extrusion block 18 is connected with the inner wall of the placing groove 8 in a sliding manner.
[0031] In the above structure, the clamping block 10 and the clamping structure 11 are made of rubber, so that the device will not be damaged when overload occurs, and the extrusion block 18 is limited by the placing groove 8.
[0032] In a preferred embodiment, the number of the extrusion block 18 and the spring 19 is four, and the four extrusion blocks 18 and the springs 19 are respectively located on the inner wall of the placing groove 8.
[0033] In the above structure, the four extrusion blocks 18 and the springs 19 can better fix the limiting rod 7 when the limiting rod 7 is placed in the inner wall of the placing groove 8, so that the connection between the circuit breaker body one 1 and the circuit breaker body two 6 is more stable.
[0034] Working principle: the control handle 3 is used to control the on-off state of the device, and when the control handle 3 is operated by the worker, the rotation of the control handle 3 drives the control structure 9 and the rotating rod 12 to rotate synchronously in the inner wall of the circuit breaker body one 1, and with the rotation of the rotating rod 12, the control structure 9 correspondingly clamps the clamping structure 11, thereby stabilizing the position of the control handle 3 and the control structure 9, in addition, the rotation of the control structure 9 also drives the moving contact 13 to move towards the outer wall of the static contact 16, and when the moving contact 13 rotates to the outer wall of the static contact 16, the device will realize the opening function, and the device is specially equipped with two groups of contacts, which can quickly cut off the circuit when the circuit is overloaded or short-circuited, thereby effectively protecting the circuit from damage, the design of double contacts not only improves the stability of contact, but also prolongs the service life and significantly reduces the failure caused by poor contact, and when the limiting rod 7 moves to the inner wall of the placing groove 8 during the connection of the circuit breaker body one 1 and the circuit breaker body two 6 by the worker, the limiting rod 7 limits the extrusion block 18, so that the extrusion block 18 drives the spring 19 to move in the inner wall of the placing groove 8 after being pressed, and with the complete entry of the limiting rod 7 into the inner wall of the placing groove 8, the elastic potential energy stored in the spring 19 is released through the limiting groove 17, the spring 19 drives the extrusion block 18 to move towards the inner wall of the limiting groove 17, thereby ensuring that the limiting rod 7 is limited and fixed in the inner wall of the placing groove 8, and finally realizing the stable connection of the circuit breaker body one 1 and the circuit breaker body two 6.
