Specific embodiments

[0022] The following will be combined with the drawings and embodiments to detail the implementation manners of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0023] As Figures 1 - 4 shown, the circuit breaker provided in this embodiment that can automatically switch on includes a mounting plate 1, on which a circuit breaker body 21 is movably mounted, and several switches 2 are movably mounted on the circuit breaker body 21. Support plates 3 are fixedly mounted on both sides of the circuit breaker body 21. A rotating rod 4 is rotatably mounted between the two support plates 3. A motor 5 connected to one end of the rotating rod 4 is fixedly mounted on one side of the support plate 3. First gears 6 are fixedly mounted on both sides of the switch 2, and several second gears 7 meshed with the first gears 6 are fixedly mounted on the rotating rod 4.

[0024] In this embodiment, by starting the motor 5, the rotating rod 4 can be driven to rotate. By the rotating rod 4, the second gear 7 can be driven to rotate. By the second gear 7, the first gear 6 can be driven to rotate. When the first gear 6 rotates to drive the switch 2 to rotate downward to the off position, the circuit can be disconnected, which is convenient for circuit maintenance or equipment debugging. After the maintenance and debugging are completed, start the motor 5 to drive the rotating rod 4 to rotate. By the rotating rod 4, the second gear 7 can be driven to rotate. By the second gear 7, the first gear 6 can be driven to rotate. When the first gear 6 rotates to drive the switch 2 to rotate upward to the on position for power supply. When operating the switch 2, manual operation is not required, preventing safety accidents such as electric shock and short circuit caused by improper operation or carelessness, avoiding damage to operators and the power system, and improving the safety of operation.

[0025] As Figure 1 and Figure 3As shown in the figure, several fixing brackets 8 are symmetrically installed on the front end face of the mounting plate 1. A fixed clamping plate 9 is fixedly installed inside the fixing bracket 8. A movable clamping plate 10 is movably installed inside the fixing bracket 8. Two sliding rods 11 are symmetrically installed on one side of the movable clamping plate 10. One end of the sliding rod 11 is movably inserted through the outer surface of the fixing bracket 8. A spring 12 is sleeved on the surface of the sliding rod 11. Both ends of the spring 12 are connected to the inner wall of the fixing bracket 8 and the surface of the movable clamping plate 10 respectively. A handle 13 is arranged on one side of the fixing bracket 8. The end of the sliding rod 11 away from the movable clamping plate 10 is fixedly connected to the handle 13. A plurality of rubber anti-slip patterns 19 are arranged on the contact surfaces of the movable clamping plate 10 and the fixed clamping plate 9 with the electric wire. The movable clamping plate 10 and the fixed clamping plate 9 are symmetrically arranged.

[0026] In this embodiment, the arrangement of the handle 13 facilitates pulling the sliding rod 11 to move upward. The upward movement of the sliding rod 11 drives the movable clamping plate 10 to move upward synchronously. When the movable clamping plate 10 moves upward, it will squeeze the spring 12 to contract. Pass the electric wire through the space between the movable clamping plate 10 and the fixed clamping plate 9. Release the handle 13 and utilize the resilience of the spring 12. The movable clamping plate 10 moves downward to abut against the electric wire, which can firmly clamp the electric wire, prevent the electric wire from loosening due to external vibration, or detaching from the circuit breaker body 21 resulting in poor contact. This helps to maintain the normal smoothness of the circuit and avoid current instability or interruption caused by electric wire problems. When fixing the electric wire, the rubber anti-slip patterns 19 can not only increase the friction with the electric wire, but also protect the electric wire to prevent damage or breakage of the electric wire when squeezing the electric wire.

[0027] As Figures 1 - 5 shown, two slide rails 14 are symmetrically installed on the mounting plate 1. A chute 15 adapted to the slide rail 14 is opened on one side of the circuit breaker body 21. A stop block 16 is fixedly installed on one side of the slide rail 14. The slide rail 14 and the circuit breaker body 21 are fixed by a first bolt 17.

[0028] In this embodiment, rotate the first bolt 17 and under the action of the thread, it continuously moves outward until it falls off the slide rail 14. When the circuit breaker body 21 is damaged, the circuit breaker body 21 can be quickly pulled out for replacement. Take a new circuit breaker body 21 and align it with the slide rail 14 through the chute 15 for quick installation, which is convenient for slidingly installing the circuit breaker body 21 on the mounting plate 1. The stop block 16 can limit the circuit breaker 21 to prevent it from detaching from the slide rail 14. Rotate the first bolt 17 and under the action of the thread, make it continuously move into the slide rail 14 to limit and fix the circuit breaker body 21 to prevent it from shaking and falling off.

[0029] As Figures 1 - 3 shown, a plurality of mounting blocks 18 are fixedly installed on both sides of the mounting plate 1. Second bolts 20 are threadedly engaged with the mounting blocks 18.

[0030] In this embodiment, through the arrangement of the mounting block 18 and the second bolt 20, it is convenient to threadedly connect and fix the circuit breaker body 21 to external equipment at a suitable position, facilitating subsequent installation and disassembly.

[0031] As Figures 1 - 5 shown, the principle of a circuit breaker that can automatically close the switch in this embodiment is as follows: By starting the motor 5, the rotating rod 4 can be driven to rotate. Through the rotating rod 4, the second gear 7 can be driven to rotate. Through the second gear 7, the first gear 6 can be driven to rotate. When the first gear 6 rotates to drive the switch 2 to rotate downward to the open position, the circuit can be disconnected, facilitating circuit maintenance or equipment debugging. After the maintenance and debugging are completed, the motor 5 is started to drive the rotating rod 4 to rotate. Through the rotating rod 4, the second gear 7 can be driven to rotate. Through the second gear 7, the first gear 6 can be driven to rotate. When the first gear 6 rotates to drive the switch 2 to rotate upward to the closed position for power supply. When operating the switch 2, manual operation is not required, preventing safety accidents such as electric shock and short circuit caused by improper operation or negligence, avoiding damage to operators and the power system, and improving the safety of operation.

[0032] As used in the specification and claims, certain terms are used to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in names as a way to distinguish components, but use the difference in functions of components as the criterion for distinction. As used throughout the specification and claims, the term "comprising" is an open-ended term and should be interpreted as "including but not limited to". "Substantially" means within an acceptable error range. Those skilled in the art can solve technical problems within a certain error range and basically achieve the technical effect.

[0033] It should be noted that the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a commodity or system including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such commodity or system. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the commodity or system including the element.

[0034] The foregoing description has shown and described several preferred embodiments of the present utility model. However, as previously mentioned, it should be understood that the present utility model is not limited to the forms disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the above teachings or the skills or knowledge in the relevant field.
