[0027] Example

[0028] See also Figures 1-4 , the utility model provides the following technical solutions:

[0029] A quick-plug circuit breaker structure for a power distribution cabinet includes:

[0030] Circuit breaker 1;

[0031] Sliding cover 2, which is arranged on the right side of the circuit breaker 1;

[0032] Sliding latches 3, two sliding latches 3 are provided, and the two sliding latches 3 are slidably connected to the sliding cover 2 and the circuit breaker 1 respectively;

[0033] A first limiting slider 4, wherein a plurality of first limiting sliders 4 are provided, and the plurality of first limiting sliders 4 are respectively fixedly connected to both side ends of the two sliding latches 3;

[0034] The springbacks 5 are provided with two springbacks 5 , both of which are fixedly connected to the circuit breaker 1 , and are respectively fixedly connected to the lower ends of the two sliding latches 3 .

[0035] In a specific embodiment of the present invention, when the sliding cover 2 is operated, the sliding latch 3 is driven to slide along the inside of the circuit breaker 1. During the sliding process, the first limit slider 4 moves along a predetermined trajectory to ensure that the sliding latch 3 slides smoothly and is positioned. At the same time, the rebounder 5 is compressed and stores force when the sliding latch 3 slides and provides a restoring force when released to reset the sliding latch 3. This structure allows the sliding cover 2 to be quickly plugged in and out, reducing maintenance time and improving work efficiency.

[0036] For details, please refer to Figures 1-4There are two first sliding grooves 6 in the circuit breaker 1, and two sliding pins 3 are slidably connected in the two first sliding grooves 6. There are multiple limiting slide rails 7 in the circuit breaker 1, and the multiple limiting slide rails 7 are slidably connected to multiple first limiting sliders 4.

[0037] In this embodiment: when the sliding latch 3 moves in the first sliding groove 6, it drives the first limit slider 4 fixedly connected to it to slide along the limit slide rail 7. There are multiple limit slide rails 7 and they are distributed inside the circuit breaker 1. The multiple limit slide rails 7 are respectively slidably connected to multiple first limit sliders 4. The movement of the first limit slider 4 limits the position of the sliding latch 3, ensuring that the inside of the circuit breaker 1 is normally opened. This design enables the circuit breaker 1 to effectively reduce maintenance time and improve work efficiency.

[0045] In this embodiment, when the circuit breaker 1 is inserted into the power distribution cabinet, the track clip 12 cooperates with the guide rail to ensure a secure installation of the circuit breaker 1. Two docking ports 13 are provided on the lower side of the circuit breaker 1. The docking ports 13 are used to dock with the connector in the power distribution cabinet. When the circuit breaker 1 is correctly installed, the docking ports 13 and the connector are automatically aligned and connected, ensuring the reliability of the electrical connection.

[0046] The working principle and use process of the utility model are as follows: when in use, first operate the sliding cover 2 to drive the sliding latch 3 to slide inside the circuit breaker 1, and the sliding latch 3 drives the first limiting slider 4 to slide along the limiting slide rail 7. Two first sliding grooves 6 are provided in the circuit breaker 1, and two sliding latches 3 are respectively slidably connected in the two first sliding grooves 6. A plurality of limiting slide rails 7 are provided in the circuit breaker 1, and a plurality of first limiting slide rails 7 are respectively slidably connected to the plurality of first limiting sliders 4. When the sliding latch 3 moves into place, the first limiting slider 4 limits the position of the sliding latch 3 to ensure that the sliding cover 2 is accurately in place. Press the push button 8 to unlock the sliding latch 3, ensuring that the sliding cover 2 is smoothly inserted or pulled out, and the circuit breaker 1 is An operating handle 11 is provided on the front side for manually operating the closing and opening actions of the circuit breaker 1. The rear end of the circuit breaker 1 is fixedly connected to a track clip 12, which is used to fix the circuit breaker 1 on the mounting rail of the distribution cabinet. Two docking ports 13 are provided on the lower side of the circuit breaker 1, which are used to dock with the connector in the distribution cabinet to ensure the reliability of the electrical connection. By using this device, the problem of increased maintenance time will be solved if the quick-plug circuit breaker in the traditional distribution cabinet fails to realize the function of quick disassembly and maintenance. The inability to quickly disassemble means that each maintenance or replacement of the circuit breaker will take more time, which will lead to prolonged production interruption time, thereby affecting work efficiency.
