[0002] A cable circuit breaker is a switching device that can close, carry, and interrupt current under normal circuit conditions and close, carry, and interrupt current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electrical energy and protect power lines. When they experience serious overloads, short circuits, or undervoltage faults, they can automatically disconnect the circuit to ensure safety in case of circuit-related problems.
[0003] Existing cable circuit breakers are cumbersome to install and inconvenient to operate. The exposed wiring openings allow dust to accumulate inside, which can easily cause internal electrical sparks and short circuits, damaging the circuit. Furthermore, the heat generated by the cable cannot be effectively dissipated, which can also cause short circuits and damage electrical equipment. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a cable circuit breaker that can be quickly installed, effectively prevents foreign objects from entering the interior, and quickly dissipates heat to ensure the safe operation of the cable.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A cable circuit breaker includes a housing, an upper cover fan mounted on the top of the housing, a limit cover rotatably connected to the outer upper end of the upper cover fan, fan plates evenly distributed below the upper cover fan, a rail post fixedly connected to the upper part of the fan plate, rail holes evenly distributed inside the upper cover fan, the outer side of the rail post slidably connected to the inside of the rail holes, a limit bar fixedly connected to the lower part of the fan plate, a lower cover fan mounted below the fan plate, the bottom of the limit bar slidably connected to a groove opened in the middle of the lower cover fan, the lower side of the upper cover fan rotatably connected to the inner side of the limit cover, the upper side of the lower cover fan fixedly connected to the inner side of the limit cover, and an adjustment assembly mounted on the rear side of the housing.
[0006] Furthermore, the adjustment assembly includes a limiting groove on the rear side of the housing, a fixed block slidably connected inside the limiting groove, a threaded post threadedly connected to the middle of the fixed block, the threaded post passing through the top of the rear side of the housing, the threaded post being rotatably connected to the rear side of the housing, a handle fixedly connected to the top of the threaded post, and an upper fixed plate fixedly connected to the rear side of the fixed block, and the housing.
[0007] Furthermore, screws are evenly installed on the front side of the housing, and a spring groove is opened on the inner side of the front end of the housing. A spring plate is slidably connected inside the spring groove. A limiting post is fixedly connected to the front end of the spring plate. A threaded ring is fixedly connected to the front end of the limiting post. A spring is installed on the outer side of the limiting post. The spring is movably connected inside the spring groove.
[0008] Furthermore, connecting blocks are fixedly connected to the front and rear sides of the limiting cover, a limiting ring is inserted through the middle of the connecting block, and the outer side of the limiting ring is threaded to the top of the shell.
[0009] Furthermore, a push shaft is rotatably connected to the front center of the housing, a push column is fixedly connected to the front side of the push shaft, and a pusher is fixedly connected to the front end of the push column.
[0010] Furthermore, a rotating ring is fixedly connected to the front end of the housing, a rotating shaft is rotatably connected inside the rotating ring, and a protective cover is fixedly connected to the front side of the rotating shaft.

The limiting strip at the bottom of the fan plate will slide along the internal groove of the lower cover fan. After opening the wiring port, the cable is connected. Rotating the throttle closes the fan plate to prevent the accumulation of internal dust from affecting work safety and improving work efficiency.
[0014] 2. In this utility model, an adjustable fixing plate is provided on the rear side of the housing. Rotating the handle drives the threaded column to rotate, causing the fixed block to move slowly downward along the limiting groove under the thread engagement. This allows the upper fixing plate to move downward and shorten the distance with the lower fixing plate, thus securing other objects. A threaded ring is installed on the outside of the screw, and a limiting column is installed inside the threaded ring. The outside is wrapped with a spring. When the screw is fully fixed, the spring has normal elasticity. When the screw is rotated outward, the spring compresses the threaded ring and moves outward with the screw, preventing the screw from falling off during rotation and improving work efficiency. The outer side of the housing is provided with air holes. During the operation of the equipment, the heat generated by the circuit is discharged and dissipated through the air holes, improving work efficiency and ensuring equipment safety.

Detailed Implementation
[0017] 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.
[0018] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a cable circuit breaker, including a housing 1. An upper cover 9 is mounted on the top of the housing 1. A limiting cover 18 is rotatably connected to the outer side of the upper end of the upper cover 9. Fan plates 21 are evenly distributed below the upper cover 9. A rail post 20 is fixedly connected to the upper part of the fan plate 21. Rail holes 22 are evenly distributed inside the upper cover 9. The outer side of the rail post 20 is slidably connected to the inside of the rail hole 22. A limiting strip 19 is fixedly connected to the lower part of the fan plate 21. The lower part is equipped with a lower cover fan 17. The bottom of the limiting strip 19 is slidably connected to the groove in the middle of the lower cover fan 17. The lower side of the upper cover fan 9 is rotatably connected to the inner side of the limiting cover 18. The upper side of the lower cover fan 17 is fixedly connected to the inner side of the limiting cover 18. The left and right sides of the upper cover fan 9 are fixedly connected with a handle 30. The front and rear sides of the limiting cover 18 are fixedly connected with a connecting block 23. A limiting ring 16 is inserted through the middle of the connecting block 23. The outer side of the limiting ring 16 is threaded to the top of the housing 1.
[0019] Specifically, during wiring installation, rotating the handle 30 causes the upper cover fan 9 to rotate. Rail holes 22 are evenly distributed on the upper cover fan 9. The rail post 20 moves along the rail holes 22 within the track, pushing the lower fan plate 21 to rotate outwards. This causes the limiting strip 19 at the bottom of the fan plate 21 to slide along the internal groove of the lower cover fan 17, allowing the fan plate 21 to move along the track of the rail holes 22, ensuring structural stability. After opening the connection port and connecting the cable, rotating the handle 30 again closes the fan plate 21, completely enveloping the outside of the cable, stabilizing the cable interface and preventing cable malfunction during operation. In the event of a detachment during the process, which could cause an electrical accident, this device can also prevent external flammable substances from entering the housing 1, avoid contact with electrical sparks that could cause an electrical fire, and improve the safety of the equipment. When storing the device, rotating the handle 30 closes the fan plate 21 to prevent internal dust accumulation from affecting work efficiency. The lower part of the upper cover fan 9 is installed on the upper inner side of the limiting cover 18, and the lower cover fan 17 is installed on the lower inner side of the limiting cover 18 to limit its movement and prevent it from derailing during rotation, thus ensuring structural stability. Connecting blocks 23 are provided on both sides of the limiting cover 18, and the connecting blocks 23 are fixed to the top of the housing 1 with limiting rings 16 to prevent detachment.
[0020] Reference Figure 1 , Figure 4 and Figure 5 A limiting groove 29 is formed on the rear side of the casing 1. A fixed block 31 is slidably connected inside the limiting groove 29. A threaded post 28 is threadedly connected to the middle of the fixed block 31. The threaded post 28 passes through the top of the rear side of the casing 1. (Refer to...) Figure 6 A handle 8 is fixedly connected to the top of the threaded post 28. An upper fixing plate 10 is fixedly connected to the rear side of the fixing block 31. A lower fixing plate 11 is fixedly connected to the lower rear end of the housing 1. Screws 5 are evenly installed on the front side of the housing 1. A spring groove 26 is opened on the inner side of the front end of the housing 1. A spring plate 27 is slidably connected inside the spring groove 26. A limiting post 24 is fixedly connected to the front end of the spring plate 27. A threaded ring 6 is fixedly connected to the front end of the limiting post 24. A threaded ring 6 is installed on the outer side of the limiting post 24. A spring 25 is movably connected inside the spring groove 26. A push shaft 12 is rotatably connected to the middle of the front end of the housing 1. A push column 14 is fixedly connected to the front side of the push shaft 12. A push handle 13 is fixedly connected to the front end of the push column 14. A rotating ring 3 is fixedly connected to the front end of the housing 1. A rotating shaft 4 is rotatably connected inside the rotating ring 3. A protective cover 2 is fixedly connected to the front side of the rotating shaft 4. An air hole 7 is fixedly connected to the upper front side of the housing 1. An indicator plate 15 is fixedly connected to the right front side of the housing 1.
[0021] Specifically, when installing the housing 1 on other objects, the handle 8 can be rotated to adjust the size of the fixed object to the required distance before installation. Rotating the handle 8 causes the threaded post 28 to rotate, moving the fixed block 31 down along the limiting groove 29. This allows the upper fixing plate 10 to move downwards, shortening the distance with the lower fixing plate 11 and securing the housing 1 to other objects, ensuring stability during operation. A screw 5 is installed on the front of the housing 1. The cable enters the housing 1 and contacts the inside; rotating the screw 5 secures the cable contact point, preventing accidental disconnection and ensuring stable circuit transmission. A threaded ring 6 protects the screw 5. The threaded ring 6 has a limiting post 24 inside and is wrapped by a spring 25 on the outside. When screw 5 is fully fixed, spring 25 has normal elasticity. When screw 5 is rotated outward, spring 25 compresses the screw ring 6 and moves outward with screw 5 to prevent screw 5 from falling off during rotation, which can speed up installation efficiency. The outer side of housing 1 is provided with air holes 7. During equipment operation, the heat generated by the circuit is discharged and dissipated through air holes 7, which improves work efficiency and ensures equipment safety. A push handle 13 is installed on the outer side of housing 1 to switch housing 1 on and off. A protective cover 2 is installed on the outer side of push handle 13 to prevent accidental contact with the switch during operation, which may cause work-related damage and ensure production safety. An indicator plate 15 is installed on the right side of the front end of housing 1, which can be used to visually observe whether the equipment is working and ensure work safety.
[0022] Working principle: When installing the wiring, rotating the handle 30 drives the upper cover fan 9 to rotate. Then, the rail hole 22 pushes the rail post 20 to move in the track and pushes the lower fan plate 21 to rotate outward. The limiting strip 19 at the bottom of the fan plate 21 will slide along the internal groove of the lower cover fan 17. After opening the wiring port, connect the cable. When rotating the handle 30 to close the fan plate 21 and fully wrap the outside of the cable for storage, rotate the handle 30 to close the fan plate 21. The fan plate 21 closes evenly to prevent internal dust accumulation from affecting work efficiency. The upper cover fan 9 and the lower cover fan 17 are respectively installed inside the limiting cover 18 to limit them and prevent them from derailing during rotation, ensuring structural stability. When installing the housing 1 on other objects, rotate the handle 8 to reach the required distance and then install it directly on top. Rotating the handle 8 drives the threaded post 28 to rotate, causing the fixed block 31 to move along the track. The limiting groove 29 moves downward, allowing the upper fixing plate 10 to move downward and shorten the distance with the lower fixing plate 11 to secure other objects. A screw ring 6 is installed on the outside of the screw 5 to protect the screw 5. When the screw 5 is fully fixed, the spring 25 has normal elasticity. When the screw 5 is rotated outward, the spring 25 compresses the screw ring 6 and moves outward with the screw 5 to prevent the screw 5 from falling off during rotation. The outer side of the housing 1 is provided with an air hole 7. During the operation of the equipment, the heat generated by the circuit is discharged and dissipated through the air hole 7 to improve work efficiency and ensure equipment safety. A push handle 13 is installed on the outside of the housing 1 to switch the housing 1 on and off. A protective cover 2 is installed on the outside of the push handle 13 to prevent accidental contact with the switch during operation and cause work-related damage, ensuring production safety. An indicator plate 15 is installed on the right side of the front end of the housing 1 to visually observe whether the equipment is working and ensure work safety.
