Description

Technical Field

[0001] This utility model relates to the field of combined central cabinet technology, and in particular to a combined central cabinet. Background Technology

[0002] A central-mounted switchgear, also known as a central-mounted power distribution cabinet, is a widely used power distribution device in power systems, primarily used in power distribution substations. It integrates power supply into a compact cabinet, using a drawer-type structure for cable connection, equipment installation, replacement, and maintenance. Modular central-mounted switchgear effectively utilizes space, increases equipment density, and saves installation space.

[0003] Traditionally, connecting cabinets in a central storage unit usually involves using tools like wrenches or screwdrivers to tighten nuts and bolts. The bolts are then passed through the threaded holes on the two components to be connected, and the nuts are screwed onto the bolts. Next, the nuts are tightened using a wrench or screwdriver. Finally, the connection is checked for security.

[0004] The above-mentioned combination connection method requires the use of special tools such as wrenches or screwdrivers to rotate the nuts to tighten or loosen the connection. This process takes time, especially when multiple bolts need to be operated, making the disassembly and assembly of the central cabinet too cumbersome and inconvenient for daily use. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a modular central cabinet, which aims to improve the problem that the traditional modular connection method is too cumbersome in terms of disassembly and assembly of the central cabinet, making it inconvenient for daily use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular central cabinet, comprising a cabinet body, a guide rail fixedly connected to the outer wall of the cabinet body, a fixing block fixedly connected to the outer wall of the cabinet body, a buckle rotatably connected between the fixing blocks, a handle fixedly connected to the outer wall of the buckle, a sliding rod slidably connected inside the buckle, a stop block fixedly connected to one end of the sliding rod, a spring fixedly connected to the outer wall of the sliding rod, the outer wall of the spring fixedly connected to the inside of the buckle, a rotating rod rotatably connected to the outer wall of the cabinet body, a baffle fixedly connected to the outer wall of the rotating rod, a retaining strip fixedly connected inside the baffle, and a moving component provided on the lower surface of the cabinet body.

[0007] Furthermore, the movable component includes casters, the upper surface of which is fixedly connected to the lower surface of the cabinet.

[0008] Furthermore, a second baffle is provided on the outer wall of the cabinet, and a hinge is fixedly connected to the outer wall of the second baffle, and the outer wall of the hinge is fixedly connected to the outer wall of the cabinet.

[0009] Furthermore, a sealing gasket is fixedly connected to the outer wall of the hinge, and the outer wall of the sealing gasket is slidably connected to the inner wall of the cabinet.

[0010] Furthermore, an exhaust vent is provided inside the cabinet, and a filter screen is fixedly connected inside the cabinet.

[0011] Furthermore, an exhaust pipe is fixedly connected to the inner wall of the cabinet, a guide pipe is fixedly connected inside the exhaust pipe, and the outer wall of the guide pipe is fixedly connected to the inner wall of the cabinet.

[0012] Furthermore, an air chamber is fixedly connected to the bottom of the exhaust pipe, an air inlet pipe is fixedly connected to the inside of the cabinet, and a fan is fixedly connected to the inner wall of the air inlet pipe.

[0013] Furthermore, a dust collection plate is fixedly connected to the inner wall of the air inlet duct, and a filter plate is fixedly connected to the inside of the cabinet.

[0014] This utility model has the following beneficial effects:

[0015] 1.

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] Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: a combined central cabinet, including a cabinet body 1, a guide rail 2 fixedly connected to the outer wall of the cabinet body 1, a fixing block 3 fixedly connected to the outer wall of the cabinet body 1, a buckle 4 rotatably connected between the fixing blocks 3, a handle 5 fixedly connected to the outer wall of the buckle 4, a sliding rod 6 slidably connected inside the buckle 4, a stop block 8 fixedly connected to one end of the sliding rod 6, a spring 7 fixedly connected to the outer wall of the sliding rod 6, the outer wall of the spring 7 fixedly connected inside the buckle 4, a rotating rod 9 rotatably connected to the outer wall of the cabinet body 1, a baffle 10 fixedly connected to the outer wall of the rotating rod 9, a retaining strip 11 fixedly connected inside the baffle 10, and a moving component provided on the lower surface of the cabinet body 1;

[0025] Specifically, when the handle 5 is turned, the buckle 4 is driven to rotate between the two fixed blocks 3, ensuring that the buckle 4 can move accurately to the required position. Next, the position of the buckle 4 is adjusted so that the central through hole is aligned with the rotating rod 9 and the baffle 10, ensuring that the buckle 4 can accurately fit against the back of the cabinet 1. The design of the buckle 4 allows it to fit tightly against the cabinet 1, providing a stable connection. Then, the rotating rod 9 is rotated, ensuring that the buckle 4 can be stably held against the back of the cabinet 1 during the rotation. As the rotating rod 9 rotates, the locking strip 11 begins to slide inside the buckle 4. During this process, the locking strip 11 applies pressure to the stop block 8, causing the sliding rod 6 to move inside the buckle 4, allowing the locking strip 11 to slide smoothly into the buckle 4. At the same time, the movement of the sliding rod 6 will compress the spring 7, which plays a role in buffering and resetting. When the locking strip 11 passes the stop block 8, the spring 7 rebounds, pushing the stop block 8 to reset, and firmly fixing the locking strip 11 inside the buckle 4, thereby achieving a firm connection between the two cabinets 1.

[0026] Reference Figure 3 and Figure 4 The moving components include casters 12, the upper surface of which is fixedly connected to the lower surface of cabinet 1; a second baffle 13 is provided on the outer wall of cabinet 1; a hinge 14 is fixedly connected to the outer wall of the second baffle 13; the outer wall of the hinge 14 is fixedly connected to the outer wall of cabinet 1; a sealing gasket 15 is fixedly connected to the outer wall of the hinge 14; the outer wall of the sealing gasket 15 is slidably connected to the inner wall of cabinet 1; an exhaust port 16 is provided inside cabinet 1; a filter screen 17 is fixedly connected inside cabinet 1; an exhaust pipe 18 is fixedly connected to the inner wall of cabinet 1; a guide pipe 19 is fixedly connected inside exhaust pipe 18; the outer wall of the guide pipe 19 is fixedly connected to the inner wall of cabinet 1; a wind chamber 20 is fixedly connected to the bottom of exhaust pipe 18; an air inlet pipe 21 is fixedly connected to the inside of cabinet 1; a fan 22 is fixedly connected to the inner wall of air inlet pipe 21; a dust collection plate 23 is fixedly connected to the inner wall of air inlet pipe 21; and a filter plate 24 is fixedly connected to the inside of cabinet 1.

[0027] Specifically, by operating the hinge 14 to rotate the baffle 13, the cabinet 1 can be easily opened or closed. Moreover, the sealing gasket 15 on the outer wall of the baffle 13 significantly enhances the sealing performance of the cabinet 1, effectively preventing the entry of external dust and impurities. Then, the fan 22 is started, and the fan 22 draws external ambient air into the air chamber 20 through the air inlet pipe 21. In this process, the air first passes through the dust collection plate 23 to remove larger dust particles, and then passes through the fine filter plate 24 to further remove small particles and impurities. The clean air after double filtration is sent into the cabinet 1. The clean air enters the guide pipe 19 through the exhaust pipe 18. The guide pipe 19 allows the air to be evenly distributed to all corners inside the cabinet 1, so that the components inside the cabinet 1 can be fully cooled and ensure their normal operation.

[0028] Working principle: When the modular central cabinet is needed, first operate the handle 5 to drive the buckle 4 to rotate between the two fixed blocks 3. Then, align the through hole in the center of the buckle 4 with the rotating rod 9 and the baffle 10 so that the buckle 4 can fit against the back of the cabinet body 1. Then rotate the rotating rod 9, using the baffle 10 to support the buckle 4, so that the locking strip 11 slides inside the buckle 4. During this process, the locking strip 11 applies pressure to the stop block 8, causing the sliding rod 6 to move inside the buckle 4 and compress the spring 7. When the locking strip 11 passes the stop block 8, the spring 7 releases its force, pushing the stop block 8 back to its original position, thereby firmly fixing the locking strip 11. Within the buckle 4, the two cabinets 1 are connected. Then, the hinge 14 is used to rotate the baffle 13 to open or close the cabinet 1. At the same time, the sealing gasket 15 on the outer wall of the baffle 13 enhances the sealing of the cabinet 1. The fan 22 is started to draw the external ambient air into the air chamber 20 through the air inlet pipe 21. When the air passes through the air inlet pipe 21, it is filtered by the dust collection plate 23 and the filter plate 24. The cleaned air enters the guide pipe 19 through the exhaust pipe 18, and is then evenly distributed to the inside of the cabinet 1 by the guide pipe 19. Finally, it is discharged through the exhaust port 16, effectively dissipating heat for the components inside the cabinet 1.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
