[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] An embodiment of the present invention provides an electric power meter box, comprising: A cabinet body 1 is provided with a cabinet door 6, a main power switch 4 is provided in the cabinet body 1, and a mechanical switch is provided on the main power switch 4; A closing component is provided on the cabinet door 6, and the closing component includes a baffle component located outside the main power switch 4, and a response component for closing the main power switch 4 by pressing; The baffle assembly includes a mounting plate 7, a baffle 9 slidably disposed on the mounting plate 7, and a lifting plate 10 disposed on the baffle 9; The response component includes a transmission component and an abutment plate 18 provided on the transmission component and abutting against the mechanical switch; After the abutment plate 18 pushes the mechanical switch horizontally, the main power switch 4 can be switched to the off state; The transmission assembly is used to horizontally push the abutment plate 18 toward the direction where the mechanical switch is located.

[0022] The cabinet body 1 and cabinet door 6 provide a secure, enclosed environment, protecting the internal electrical components from external influences and preventing unauthorized access. The main power switch 4 controls the circuit breaker for the entire power meter box, ensuring normal equipment operation. In an emergency, it mechanically shuts off power to protect the system and personnel. The mechanical switch is an operating component on the main power switch that allows physical control of the switch's on / off state.

[0023] In addition, the cabinet 1 is usually placed in a container with a safety lock, such as a safety cabinet or a room with an anti-theft door, to ensure that only people with control authority can manipulate the switch to close the circuit.

[0024] The closing assembly is used to quickly shut off the main power switch in an emergency without direct contact, enhancing operational safety. The baffle assembly protects the main power switch 4 when circuit closure is not required. The response assembly, through the coordinated action of the transmission assembly and abutment plate 18, achieves non-contact, rapid, and stable shutoff of the main power switch.

[0025] There are many types of switches in the cabinet 1 for managing the opening or closing of power, but they can be generally divided into a main power switch 4 and several sub-power controllers. The abutment plate 18 must ensure that it is directly abutted against the mechanical switch of the main power switch 4 to ensure that the power supply of all electrical devices in the cabinet 1 can be turned off during operation.

[0026] The transmission assembly includes a moving column 11, a squeezing ball 13 disposed at the bottom of the moving column 11, and a pressure plate 15 disposed outside the abutment plate 18 and abutting against the squeezing ball 13; The lifting plate 10 is provided with a cavity, and the transmission assembly and at least part of the structure of the pressure plate 15 are arranged in the cavity; The contact surface between the pressure plate 15 and the squeezing ball 13 is configured as an inclined surface.

[0027] A reset tension spring 14 is provided between the squeezing ball 13 and the inner side surface of the lifting plate 10 , a limiting plate 16 is provided on the pressure plate 15 , and a tension spring 17 is fixedly connected between the limiting plate 16 and the baffle 9 .

[0028] A limiting plate 12 is provided at the top of the movable column 11 .

[0029] A movable groove is provided on the inner side of the baffle 9 , and the pressure plate 15 is slidably arranged in the movable groove.

[0030] The movable column 11 is a vertical columnar structure, connected at its top to a limit plate 12 and at its bottom to a squeeze ball 13. The limit plate 12, which can be a disc, is fixed to the top of the movable column. The squeeze ball 13 is a hemispherical structure fixed to the bottom of the movable column. By contacting the pressure plate 15, it transmits a vertical compressive force, causing the pressure plate 15 to move.

[0031] The return spring 14 is an elastic element connected between the top of the squeezing ball and the inner wall of the lifting plate. Its purpose is to return the squeezing ball 13 and related components to their initial position after the force is removed. The pressure plate 15 is a plate-like structure with a surface in contact with the squeezing ball 13 and can slide within the movable groove. The contact surface of the pressure plate 15 and the squeezing ball 13 has an arc shape that matches the squeezing ball 13.

[0032] The limit plate 16 is a plate that fits over the surface of the pressure plate 15 and is used to limit the movement of the pressure plate 15, primarily its lateral movement, ensuring that it slides along the predetermined path within the movable groove. A tension spring, a relatively low-elasticity spring, is connected between the limit plate and the inner wall of the movable groove. It provides additional positioning and reset force for the pressure plate, ensuring that it quickly returns to its initial position when no longer pushed. The movable groove is a groove-like structure within the baffle that provides a sliding path for the pressure plate 15, guiding its movement and ensuring that it slides along the predetermined path.

[0033] A sliding groove is provided on one side of the mounting plate 7 , and a clamping strip is fixedly connected to the side of the baffle 9 , and the clamping strip is slidably arranged inside the sliding groove.

[0034] The clip is a long, protruding structure fixed to the side of the baffle 9. It slides within the chute of the mounting plate 7, guiding and securing the baffle 9, ensuring smooth movement along the chute. The chute provides a track that limits the direction of movement of the baffle 9, ensuring it slides along a specific path and preventing it from moving sideways or falling out of the chute.

[0035] The cabinet door 6 is provided with a window, and the mounting plate 7 is arranged on the side of the window.

[0036] Two groups of mounting plates 7 are provided, and a connection frame 8 is installed between the two mounting plates 7 . The connection frame 8 is provided on the outside of the main power switch 4 .

[0037] Furthermore, a key lock is installed on the cabinet door, and a blocking piece is fixedly connected to one side of the key lock.

[0038] Among them, the key lock is a lock installed on the cabinet door. It can be composed of a lock cylinder, keyhole, lock tongue, etc., with the purpose of providing physical security and restricting access to the components inside the cabinet. It can only be unlocked with a matching key, thus preventing unauthorized personnel from opening the cabinet door. The baffle is fixedly connected to one side of the key lock. It is usually a flat piece of metal or other solid material. The baffle is locked into a specific position in the locked state to prevent the cabinet door from being opened. It can also provide additional mechanical stability to ensure that the lock is not easily pried open in the locked state.

[0039] Furthermore, a square groove is provided on the cabinet door, and a locking plate is installed on the cabinet body, and the locking plate is arranged inside the square groove.

[0040] A protective cover 19 is rotatably connected to the top of the lifting plate 10 .

[0041] The protective cover 19 can be made of metal, plastic, or other durable materials to resist environmental influences such as dust, moisture, and physical damage. It can be box-shaped, semicircular, or otherwise designed to effectively cover the top of the lifting plate and surrounding components. The protective cover 19 is connected to the top of the lifting plate via a hinge or pivot, allowing it to rotate open and closed.

[0042] The contact plate 18 is a soft plate, and a side of the contact plate 18 close to the main power switch 4 is provided with an arc surface.

[0045] The regulating component is used to open the baffle 9 and turn off the main power switch 4. The regulating component includes two mounting plates 7. A connecting frame 8 is installed on the back of the two mounting plates 7. A window is provided on the front of the cabinet door 6. The two mounting plates 7 are respectively arranged on both sides of the window. The cabinet door 6, the mounting plate 7 and the connecting frame 8 are connected by bolts, which is convenient for switching the main power switch 4 through the window. The connecting frame 8 is arranged on the outside of the main power switch 4. A baffle 9 is slidably connected between the two mounting plates 7. A slide groove is provided on one side of the mounting plate 7. Both sides of the baffle 9 are fixedly connected with a card strip, and the card strip is slidably arranged inside the slide groove to ensure the normal movement of the baffle 9. A lifting plate 10 is installed on the front of the baffle 9, and a changing component is installed inside the lifting plate 10.

[0046] The changing component is used to turn off the main power switch 4 during the process of opening the baffle 9. The changing component includes a moving column 11. The top of the lifting plate 10 is provided with a limiting hole for the moving column 11 to pass through, which ensures the normal movement of the moving column 11. The top of the moving column 11 is fixedly connected to the limiting disk 12. The top of the lifting plate 10 is rotatably connected to a protective cover 19, which is used to control whether the limiting disk 12 is pressed during use. The bottom of the moving column 11 is fixedly connected to a squeezing ball 13. The top of the squeezing ball 13 and the top of the inner wall of the lifting plate 10 are connected by a reset spring 14. The surface of the squeezing ball 13 abuts against a pressure plate 15. The front of the pressure plate 15 is a triangular block, which is convenient for the pressure plate 15 to be squeezed by the squeezing ball 13, the surface of the pressure plate 15 is sleeved with a limit plate 16, the inside of the baffle 9 is provided with a moving groove, the back of the lifting plate 10 and the front of the moving groove are provided with a through groove, the pressure plate 15 is slidably arranged inside the through groove, ensuring the normal movement of the pressure plate 15, the pressure plate 15 is slidably arranged inside the moving groove, the front of the limit plate 16 is fixedly connected to two tension springs 17, the front of the tension spring 17 is fixedly connected to the front of the inner wall of the moving groove, one end of the pressure plate 15 is fixedly connected to the abutment plate 18, the abutment plate 18 is a rubber plate, and the top and bottom of the back of the abutment plate 18 are provided with arc surfaces, which reduce the damage caused by the abutment plate 18 to the surface of the main power switch 4.

[0047] The implementation principle of an electricity meter box in the embodiment of the present application is: when it is necessary to turn off the main power switch 4, the lifting plate 10 is pulled upward, so that the lifting plate 10 lifts the baffle 9 upward. At this time, the main power switch 4 is connected to the outside world through the window, and the operator can directly turn the switch on the main power switch 4. When it is necessary to turn on the main power switch 4, the lifting plate 10 is directly pulled up to reset the switch on the main power switch 4. The lifting plate 10 is used to directly control the switch of the main power switch 4 without opening the cabinet door 6. It is very convenient and quick. In case of emergency, the time for opening the cabinet door 6 is reduced, and the emergency capability of the device is improved.

[0048] In case of emergency, the protective cover 19 can be directly pushed to one side, and then the limit plate 12 can be pressed and the lifting plate 10 can be lifted upward. During this process, the limit plate 12 will move downward with the movable column 11, so that the squeezing ball 13 will squeeze the pressure plate 15 downward, so that the pressure plate 15 moves toward the inside of the cabinet 1, thereby causing the pressure plate 15 to move toward the main power switch 4 with the abutment plate 18. In the process of lifting the lifting plate 10 upward, the abutment plate 18 will abut the switch on the main power switch 4 and push the switch upward, thereby realizing the automatic closing of the main power switch 4 in the process of lifting the lifting plate 10, which can further reduce the time to close the main power switch 4 and make it more convenient to close the main power switch 4.
