Technical Field

[0001] This utility model relates to the technical field of lightning protection and leakage current circuit breakers, specifically to a lightning protection and leakage current circuit breaker that is easy to maintain. Background Technology

[0002] A lightning protection circuit breaker is an electrical protection device that integrates lightning protection, leakage protection, and short-circuit protection. It can quickly disconnect the circuit in the event of lightning overvoltage or power grid abnormalities, protecting electrical equipment and personal safety. This circuit breaker has multiple functions such as overvoltage protection, leakage protection, and short-circuit protection, and can effectively reduce the risk of lightning strikes and electrical fires. It is suitable for homes, businesses, and industries, and is an important piece of equipment to ensure the safe operation of the power system.

[0003] Existing surge protection and residual current circuit breakers (SPCBs) require mounting on a distribution box or bracket before wiring. After a period of use, they need maintenance. If problems are found requiring further repair or replacement, the SPCB must be removed. However, the mounting screws are typically located behind the bracket, which is usually mounted on the box wall or wall. This obstructs the view of the screws, making disassembly difficult and hindering maintenance. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a new technical solution: a lightning protection leakage circuit breaker that is easy to maintain, including a bracket 1, a lightning protection leakage circuit breaker 2 installed on the front surface of the bracket 1, and mounting plates 3 fixedly installed at both ends of the rear surface of the lightning protection leakage circuit breaker 2. Fixing screws 4 are rotatably installed on the far surfaces of the two mounting plates 3, and the near ends of the two fixing screws 4 are rotatably inserted into the interior of the bracket 1. The two fixing screws 4 are threadedly connected to the two mounting plates 3 and the bracket 1 respectively.

[0025] The stabilizing mechanism is located inside the upper mounting plate 3. The stabilizing mechanism includes a toothed plate 5 and a pressing plate 6. A T-shaped mounting groove 7 is provided inside the upper mounting plate 3. The lower surface of the T-shaped mounting groove 7 is open. A first mounting groove 8 is also provided inside the upper mounting plate 3. The first mounting groove 8 communicates with the interior of the T-shaped mounting groove 7. The toothed plate 5 is slidably mounted on the inner wall of the T-shaped mounting groove 7. The pressing plate 6 is fixedly mounted on the front surface of the toothed plate 5.

[0026] Furthermore, the stabilizing mechanism also includes a connecting rod 9 and a gear 10. The connecting rod 9 is rotatably mounted on the inner wall of the first mounting groove 8, and the gear 10 is fixedly mounted on the outer surface of the connecting rod 9. The gear 10 meshes with the toothed plate 5, and the upper mounting plate 3 has a second mounting groove 11 inside.

[0027] Furthermore, the right end of the connecting rod 9 rotates through into the interior of the second mounting groove 11, and a rotating rod 12 is rotatably mounted on the upper surface of the mounting plate 3. The lower end of the rotating rod 12 rotates through into the interior of the second mounting groove 11. Both the right end of the connecting rod 9 and the lower end of the rotating rod 12 are fixedly mounted with bevel gears 13, and the two bevel gears 13 mesh with each other.

[0028] Furthermore, there are two stabilizing mechanisms, which are respectively installed inside the two mounting plates 3 on the upper and lower sides. The two stabilizing mechanisms are set with a 180-degree rotation around the center point between them.

[0029] Furthermore, by fixing the two mounting plates 3 to the bracket 1 with two fixing screws 4, the lightning protection circuit breaker 2 can be disassembled, which facilitates the maintenance and replacement of the lightning protection circuit breaker 2 by the staff. During use, the two compression plates 6 fill and compress the space between the bracket 1 and the lightning protection circuit breaker 2, increasing the stability between the bracket 1 and the lightning protection circuit breaker 2, thereby improving the practicality of the circuit breaker.

[0030] Furthermore, rectangular holes 14 are provided on the distant surfaces of the two mounting plates 3, and the two rectangular holes 14 communicate with the interior of the corresponding T-shaped mounting grooves 7.

[0031] Furthermore, limit grooves 15 are provided on the left and right inner walls of the two T-shaped mounting grooves 7, and limit plates 16 are slidably installed inside the four limit grooves 15. The four limit plates 16 are respectively fixedly connected to the corresponding toothed plates 5.

[0032] Furthermore, during maintenance of this circuit breaker, the operator can rotate the two rotating rods 12, causing each rod 12 to drive the bevel gear 13 fixedly connected to it to rotate. This, in turn, causes the connecting rod 9 fixedly connected to it to rotate. The rotation of the connecting rod 9 drives the gear 10 fixedly connected to it to rotate. The rotation of the gear 10 causes the toothed plate 5 meshing with it to move up and down, causing the two rotating rods 12 to move away from each other. This causes the two toothed plates 5 to move away from each other, and the two pressing plates 6 to move away from each other. The two pressing plates 6 move away from each other and away from the bracket 1 and the lightning protection circuit breaker 2, loosening the connection between the bracket 1 and the lightning protection circuit breaker 2. At this point, the two fixing screws 4 can be rotated from above and below the bracket 1, allowing the operator to see and remove them. This removes the two fixing screws 4 from the bracket 1 and the mounting plate 3, allowing the lightning protection circuit breaker 2 to be removed for easy maintenance and replacement.
