Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and in particular to a low-voltage power distribution cabinet and its usage method. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] In existing technologies, the doors of most distribution cabinets are hinged, which means that the doors often move during electrical circuit maintenance, thus hindering the maintenance work. To address this problem, we propose a low-voltage distribution cabinet and its usage method. Summary of the Invention

[0004] The purpose of this application is to provide a low-voltage distribution cabinet and its usage method to solve the problem mentioned in the background art that most of the cabinet doors of the distribution cabinets are hinged, so the cabinet doors will often move during the electrical maintenance process, thus hindering the electrical maintenance.

[0005] To achieve the above objectives, this application provides the following technical solution: a low-voltage distribution cabinet, comprising a main body, and further comprising: The cabinet has two doors, both of which are located on the front side of the low-voltage distribution cabinet body. The hinge assembly consists of six parts, including a connecting block, a rotating shaft, and two support sleeves. One end of the connecting block is fixedly installed on one side of the corresponding cabinet door, and the connecting block is fixedly sleeved on the rotating shaft. Both support sleeves are rotatably sleeved on the corresponding rotating shafts, and the rear ends of both support sleeves are fixedly installed on the front side of the low-voltage distribution cabinet body. Two circular shafts are provided, with the bottom end of each shaft fixedly mounted on the top end of a corresponding rotating shaft, and the top ends of both shafts fixedly mounted on a gear. The limiting assembly includes: two housings, two adapter rods, two first springs, two transmission rods, two moving rods, two rotating rods, a horizontal plate, a pressure rod, and a lifting plate. The bottoms of the two housings are fixedly installed on the top of the low-voltage distribution cabinet body. The top ends of the adapter rods are slidably connected to the inner walls of the corresponding housings. The bottom ends of the adapter rods engage with corresponding gears. The ends of the two first springs that are far apart are fixedly installed on the inner walls of the two housings, and the ends of the two first springs that are close together are fixedly installed on the two adapter rods. The ends of the two transmission rods that are far apart pass through the sides of the two housings that are close together and are fixedly installed on the two adapter rods. The two moving rods are fixedly installed on the ends of the two transmission rods that are close together. The bottom ends of the two moving rods are slidably connected to the top of the low-voltage distribution cabinet body. The ends of the two rotating rods that are close together are rotatably connected to the two moving rods. The bottom of the horizontal plate is fixedly installed on the top of the two housings. The ends of the two rotating rods that are close together are rotatably connected to the bottom of the lifting plate. The bottom end of the pressure rod passes through the horizontal plate and is fixedly installed on the top of the lifting plate. A positioning component is provided, which is located on the top of the low-voltage distribution cabinet body and cooperates with the bottom of the lifting plate.

[0006] Using the above structure, the cabinet door is connected to the main body of the low-voltage distribution cabinet via a hinge assembly. The rotating shaft and support sleeve provide stable rotational support. When the cabinet door is opened to a certain angle, pressing down the pressure rod can drive the lifting plate to move down. At this time, the lifting plate can drive the two rotating rods to move, thereby pushing the two moving rods away from each other. Then, the two moving rods can drive the two transmission rods and the two adapter rods to move away from each other. Then, by engaging the teeth on the two gears with the bottom ends of the two adapter rods, the rotation of the gears and the shaft can be restricted. This restricts the rotation of the two uppermost rotating shafts, thereby achieving rotational limit of the two cabinet doors. This ensures the stability of the cabinet door when it is open and prevents the movement of the cabinet door from hindering the electrician's maintenance of the circuit.

[0007] Preferably, a first sliding groove is provided on the top inner wall of both boxes, and the top end of the adapter rod is slidably connected in the corresponding first sliding groove.

[0008] Furthermore, the first slide groove guides the top of the adapter rod to slide smoothly, ensuring that the adapter rod moves smoothly within the housing, avoiding jamming or deviation, and ensuring accurate engagement between the adapter rod and the gear. This improves the response accuracy and reliability of the limit component. The first slide groove has a simple structure, is easy to maintain, and extends the service life of the component.

[0009] Preferably, the top of the low-voltage distribution cabinet body has two second sliding grooves, and the bottom end of the moving rod is slidably connected in the corresponding second sliding groove.

[0010] Furthermore, the second slide groove accommodates the sliding of the bottom end of the moving rod, allowing the moving rod to move smoothly on the top of the low-voltage distribution cabinet body, reducing friction when transmitting force, ensuring coordinated movement of the transmission rod and the moving rod, and preventing component deformation or damage. The second slide groove design enhances the guiding nature of the moving rod and improves the overall stability of the limit assembly.

[0011] Preferably, two stabilizing rods are fixedly installed on the top of the lifting plate, and the top ends of the two stabilizing rods penetrate through the horizontal plate and are slidably connected to the horizontal plate.

[0012] Furthermore, the lifting plate and the horizontal plate are connected by a stabilizer bar, which provides additional support and guidance to prevent the lifting plate from tilting or swaying during lifting and lowering, ensuring smooth operation of the pressure bar. The stabilizer bar slides to connect the horizontal plate to enhance structural rigidity, reduce the impact of vibration, and improve the accuracy and durability of the limit components.

[0013] Preferably, two second springs are fixedly installed at the bottom of the lifting plate, and the bottom ends of the two second springs are fixedly installed at the top of the low-voltage distribution cabinet body.

[0014] Furthermore, a second spring connects the lifting plate to the top of the low-voltage distribution cabinet body, providing buffering and restoring force. When the limit component is released, it helps the lifting plate quickly return to the initial position, reducing manual adjustment. The second spring absorbs the impact of movement, keeping the component movement smooth and extending the service life of the equipment.

[0015] Preferably, the positioning component includes a buckle, a slider, and a locking rod. The top of the buckle is fixedly installed on the bottom of the lifting plate. A third sliding groove is provided on the top of the low-voltage distribution cabinet body. The slider is slidably connected in the third sliding groove. The bottom end of the locking rod is fixedly installed on the top of the slider. The top end of the locking rod cooperates with the buckle.

[0016] Furthermore, the buckle and lever in the positioning component work together to lock the bottom position of the lifting plate, preventing the lifting plate from rising accidentally and ensuring that the cabinet door is securely fixed. The slider slides in the third slide groove to make the lever move smoothly. The engagement of the lever and buckle enhances the locking force and improves the safety and stability during maintenance.

[0017] Preferably, a third spring is fixedly installed on the left inner wall of the third slide groove, and the right end of the third spring is fixedly installed on the left side of the slider.

[0018] Furthermore, a third spring connects the slider to the inner wall of the third groove, providing an automatic reset force for the slider. The elasticity of the third spring ensures smooth automatic engagement of the lever and the buckle, enhancing the reliability of the component.

[0019] Preferably, a pull rod is fixedly installed on the left side of the lever.

[0020] Furthermore, the device is fixed to the locking lever by a pull rod, making it easy to manually pull the locking lever to release the lock, which is labor-saving and quick to operate.

[0021] This invention also proposes a method for using a low-voltage distribution cabinet, comprising the following steps: S1: First, the cabinet door is connected to the main body of the low-voltage distribution cabinet through a hinge assembly. The rotating shaft and support sleeve provide stable rotational support, thereby achieving stable hinge support for the cabinet door. S2: When the cabinet door is opened to a certain angle, the lifting plate can be moved down by pressing down the pressure rod. At this time, through the transmission between the lifting plate and the two adapter rods, the two adapter rods can be moved away from each other. Then, the bottom ends of the two adapter rods are engaged with the teeth on the two gears, which can limit the rotation of the gears and the shaft. This can limit the rotation of the two uppermost rotating shafts, thereby achieving the rotation limit of the two cabinet doors. S3: At the same time, when the lifting plate moves down, it can drive the buckle to move down, and through the cooperation of the buckle and the lever, lock the bottom position of the lifting plate to prevent the lifting plate from rising accidentally and ensure that the cabinet door is fixed and reliable.

[0022] The beneficial effects of this invention are: 1. The cabinet door is connected to the main body of the low-voltage distribution cabinet via a hinge assembly. The rotating shaft and support sleeve provide stable rotational support. When the cabinet door is opened to a certain angle, pressing down the pressure rod can drive the lifting plate to move down. At this time, the lifting plate can drive the two rotating rods to move, thereby pushing the two moving rods away from each other. Then, the two moving rods can drive the two transmission rods and the two adapter rods to move away from each other. Then, the bottom ends of the two adapter rods are engaged with the teeth on the two gears, which can limit the rotation of the gears and the shaft. This can limit the rotation of the two uppermost rotating shafts, thereby achieving rotation limit of the two cabinet doors. This can ensure the stability of the cabinet door when it is open and prevent the movement of the cabinet door from hindering the electrician's maintenance of the circuit. 2. The bottom position of the lifting plate is locked by the buckle and the lever in the positioning component to prevent the lifting plate from rising accidentally and to ensure that the cabinet door is fixed and reliable. The slider slides in the third slide groove to make the lever move smoothly. The engagement of the lever and the buckle enhances the locking force and improves the safety and stability during maintenance. This invention, through its simple structure, enables arbitrary positioning of the cabinet door when maintaining the electrical components inside the low-voltage distribution cabinet. It is highly adaptable, improves the stability of the cabinet door, and prevents the movement of the cabinet door from hindering the electrician's maintenance of the circuit. It is highly practical.

The bottoms of the two housings 8 are fixedly installed on the top of the low-voltage distribution cabinet body 1. The top ends of the adapter rods 9 are slidably connected to the inner top wall of the corresponding housing 8, and the bottom ends of the adapter rods 9 engage with the corresponding gears 7. The ends of the two first springs 11 that are far apart are fixedly installed on the inner walls of the two housings 8, and the ends of the two first springs 11 that are close together are fixedly installed on the two adapter rods 9. The ends of the moving rods 12 that are far apart pass through the sides of the two boxes 8 that are close to each other and are fixedly installed on the two adapter rods 9. The two moving rods 13 are fixedly installed on the ends of the two transmission rods 12 that are close to each other. The bottom ends of the two moving rods 13 are slidably connected to the top of the low-voltage distribution cabinet body 1. The ends of the two rotating rods 15 that are close to each other are rotatably connected to the two moving rods 13. The bottom of the horizontal plate 16 is fixedly installed on the top of the two boxes 8. The ends of the two rotating rods 15 that are close to each other are rotatably connected to the bottom of the lifting plate 18. The bottom end of the pressure rod 17 passes through the horizontal plate 16 and is fixedly installed on the top of the lifting plate 18. The positioning component is located on the top of the low-voltage distribution cabinet body 1 and cooperates with the bottom of the lifting plate 18.

[0027] With the above structure, the cabinet door 2 is connected to the low-voltage distribution cabinet body 1 by a hinge assembly. The rotating shaft 4 and the support sleeve 5 provide stable rotational support. When the cabinet door 2 is opened to a certain angle, the lifting plate 18 can be moved down by pressing down the pressure rod 17. At this time, the lifting plate 18 can drive the two rotating rods 15 to move, thereby pushing the two moving rods 13 away from each other. At this time, the two moving rods 13 can drive the two transmission rods 12 and the two adapter rods 9 to move away from each other. Then, by engaging the teeth on the two gears 7 with the bottom ends of the two adapter rods 9, the rotation of the gears 7 and the round shaft 6 can be restricted. This restricts the rotation of the two uppermost rotating shafts 4, thereby achieving rotation limit of the two cabinet doors 2, thus ensuring the stability of the cabinet door 2 when it is opened and preventing the movement of the cabinet door 2 from hindering the electrician's maintenance of the circuit.

[0028] In this embodiment, a first sliding groove 10 is provided on the top inner wall of both housings 8. The top end of the adapter rod 9 is slidably connected in the corresponding first sliding groove 10. The first sliding groove 10 guides the top end of the adapter rod 9 to slide, so that the adapter rod 9 moves smoothly in the housing 8, avoiding jamming or deviation, ensuring accurate matching between the adapter rod 9 and the gear 7, improving the response accuracy and reliability of the limiting component. The first sliding groove 10 has a simple structure, is easy to maintain, and extends the service life of the component.

[0029] In this embodiment, two second slide grooves 14 are provided on the top of the low-voltage distribution cabinet body 1. The bottom end of the moving rod 13 is slidably connected in the corresponding second slide groove 14. The second slide groove 14 accommodates the sliding of the bottom end of the moving rod 13, so that the moving rod 13 moves smoothly on the top of the low-voltage distribution cabinet body 1, reduces friction when transmitting force, ensures coordinated movement of the transmission rod 12 and the moving rod 13, and prevents deformation or damage of the components. The design of the second slide groove 14 enhances the guiding nature of the moving rod 13 and improves the overall stability of the limiting component.

[0030] In this embodiment, two stabilizing rods 19 are fixedly installed on the top of the lifting plate 18. The top ends of the two stabilizing rods 19 pass through the horizontal plate 16 and are slidably connected to the horizontal plate 16. The stabilizing rods 19 connect the lifting plate 18 and the horizontal plate 16, providing additional support and guidance to prevent the lifting plate 18 from tilting or shaking during the lifting process, ensuring that the pressure rod 17 operates smoothly. The slidable connection of the stabilizing rods 19 to the horizontal plate 16 enhances the structural rigidity, reduces the impact of vibration, and improves the accuracy and durability of the limiting components.

[0031] In this embodiment, two second springs 20 are fixedly installed at the bottom of the lifting plate 18. The bottom ends of the two second springs 20 are fixedly installed at the top of the low-voltage distribution cabinet body 1. The lifting plate 18 is connected to the top of the low-voltage distribution cabinet body 1 through the second springs 20, providing buffering and restoring force. When the limit component is released, it helps the lifting plate 18 to quickly return to the initial position, reducing manual adjustment. The second springs 20 absorb the impact of movement, keep the component movement gentle, and extend the service life of the equipment.

[0032] In this embodiment, the positioning component includes a buckle 21, a slider 23, and a locking rod 25. The top of the buckle 21 is fixedly installed at the bottom of the lifting plate 18. A third slide groove 22 is provided on the top of the low-voltage distribution cabinet body 1. The slider 23 is slidably connected in the third slide groove 22. The bottom end of the locking rod 25 is fixedly installed at the top of the slider 23. The top end of the locking rod 25 cooperates with the buckle 21. By cooperating with the locking rod 25 in the positioning component, the bottom position of the lifting plate 18 is locked to prevent the lifting plate 18 from rising accidentally and to ensure that the cabinet door 2 is fixed reliably. The slider 23 slides in the third slide groove 22 to make the locking rod 25 move smoothly. The engagement of the locking rod 25 with the buckle 21 enhances the locking force and improves the safety and stability during maintenance.

[0033] In this embodiment, a third spring 24 is fixedly installed on the inner wall of the left side of the third slide groove 22, and the right end of the third spring 24 is fixedly installed on the left side of the slider 23. The slider 23 is connected to the inner wall of the third slide groove 22 through the third spring 24, providing an automatic reset force for the slider 23. The elasticity of the third spring 24 ensures that the locking rod 25 and the buckle 21 automatically engage smoothly, enhancing the reliability of the component.

[0034] In this embodiment, a pull rod 26 is fixedly installed on the left side of the locking rod 25. The pull rod 26 is fixedly installed on the locking rod 25, which makes it easy to manually pull the locking rod 25 to unlock it, and the operation is labor-saving and quick.

[0035] This invention also proposes a method for using a low-voltage distribution cabinet, comprising the following steps: S1: First, the cabinet door 2 is connected to the low-voltage distribution cabinet body 1 through the hinge assembly. The rotating shaft 4 and the support sleeve 5 provide stable rotation support to achieve stable hinge support for the cabinet door 2. S2: Then, when the cabinet door 2 is opened to a certain angle, the lifting plate 18 can be moved down by pressing down the pressure rod 17. At this time, through the transmission between the lifting plate 18 and the two adapter rods 9, the two adapter rods 9 can be moved away from each other. Then, through the engagement of the bottom ends of the two adapter rods 9 with the teeth on the two gears 7, the rotation of the gears 7 and the round shaft 6 can be restricted. At this time, the rotation of the two uppermost rotating shafts 4 can be restricted, thereby achieving the rotation limit of the two cabinet doors 2. S3: At the same time, when the lifting plate 18 moves down, it can drive the buckle 21 to move down, and through the cooperation of the buckle 21 and the lever 25, it locks the bottom position of the lifting plate 18, preventing the lifting plate 18 from rising accidentally and ensuring that the cabinet door 2 is fixed and reliable.

[0036] Working principle: In use, the cabinet door 2 is first connected to the low-voltage distribution cabinet body 1 via a hinge assembly. The rotating shaft 4 and support sleeve 5 provide stable rotational support. Then, when the cabinet door 2 is opened to a certain angle, pressing down the pressure rod 17 can drive the lifting plate 18 to move downward. At this time, the lifting plate 18 can drive the two rotating rods 15 to move, thereby pushing the two moving rods 13 away from each other. Then, the two moving rods 13 can drive the two transmission rods 12 and the two adapter rods 9 to move away from each other. Then, by engaging the teeth on the two gears 7 with the bottom ends of the two adapter rods 9, the rotation of the gears 7 and the round shaft 6 can be restricted. This mechanism restricts the rotation of the two uppermost rotating shafts 4, thereby limiting the rotation of the two cabinet doors 2. This ensures the stability of the cabinet doors 2 when they are open and prevents their movement from hindering the electrician's circuit maintenance. Simultaneously, when the lifting plate 18 moves down, it can drive the latch 21 down. The latch 21 and the latch rod 25 work together to lock the bottom position of the lifting plate 18, preventing the lifting plate 18 from rising accidentally and ensuring that the cabinet doors 2 are securely fixed. The slider 23 slides in the third slide groove 22, allowing the latch rod 25 to move smoothly. The engagement of the latch rod 25 and the latch 21 enhances the locking force, improving safety and stability during maintenance.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
