Description

Technical Field

[0001] This invention belongs to the field of power distribution cabinet technology, specifically relating to an XL assembled power distribution cabinet. Background Technology

[0002] A power distribution box, also known as a power control box, is a type of distribution box. Distribution boxes are divided into power distribution boxes and lighting distribution boxes. They are the final stage equipment in a power distribution system. A distribution box is a low-voltage power distribution device formed by assembling switching equipment, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements.

[0003] Traditional power distribution cabinets have rigid frame structures and mounting brackets. The frame structures and mounting brackets are mostly connected to the cabinet with screws. The positions of the components inside the cabinet are fixed and the space is fixed. Only the corresponding matching electronic components can be installed in appropriate positions, which has poor applicability. Moreover, the electronic components are densely installed, and disassembly and maintenance are inconvenient. To address this, we propose an XL-type assembled power distribution cabinet. Summary of the Invention

[0004] The purpose of this invention is to provide an XL-type assembled power distribution cabinet with a simple structure and reasonable design in order to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] An XL-type modular power distribution cabinet includes a cabinet body with a top plate on the upper part. A connecting frame is fixedly installed on the lower end face of the top plate. A U-shaped connecting groove is formed on the lower end face of the connecting frame. The upper wall of the cabinet body is inserted into the connecting groove. A U-shaped fixing frame is vertically slidably fitted on the inner wall of the cabinet body. The fixing frame is connected to the cabinet body through a plug-in mechanism. T-shaped mounting grooves are formed at equal intervals on both side walls of the fixing frame. A mounting strip is horizontally attached to the outer wall of the fixing frame. The mounting strip has evenly spaced mounting holes. T-shaped connectors are horizontally fixedly installed on the outer walls at both ends of the mounting strip. The connectors movably pass through the mounting grooves.

[0007] As a further optimization of the present invention, the plug-in mechanism includes a rack that is horizontally fixedly installed on the lower part of the inner wall on both sides of the cabinet, and plug-in strips are respectively fixedly installed at both ends of the lower end face of the fixed frame, and the plug-in strips are plugged into the grooves of the rack.

[0008] As a further optimization of the present invention, the inner wall of the connecting groove is provided with a groove in the horizontal direction, and a snap-fit ​​component is provided in the groove. The snap-fit ​​component is fixedly connected to the inner wall of the groove by a spring.

[0009] As a further optimization of the present invention, a limiting block is provided at one end of the snap-fit ​​component facing the groove, the limiting block slides with the inner wall of the groove, the end of the snap-fit ​​component is hemispherical, and the snap-fit ​​component is movably embedded in the outer wall of the cabinet.

[0010] As a further optimization of the present invention, the middle part of the connector is cylindrical, the diameter of the cross-section of the middle part of the connector is the same as the width of the lower part of the mounting groove, and the connector slides with the outer wall of the fixed frame.

[0011] As a further optimization of the present invention, multiple ventilation slots are provided on both sides of the cabinet. A mesh plate is fixedly installed inside the ventilation slot, and a shielding component that fits against the cabinet is provided on the outside of the ventilation slot. Multiple shielding components are fixedly connected by a connecting frame, and the connecting frame is fixedly connected to the cabinet by screws.

[0012] As a further optimization of the present invention, a plurality of L-shaped limiting members are fixedly installed on the outer wall of the cabinet, and the limiting members are fitted with the corner of the connecting frame.

[0013] As a further optimization of the present invention, a placement frame is fixedly installed on the bottom surface of the cabinet, and a drying box that slides in cooperation with the inner wall of the placement frame is placed on the bottom surface of the cabinet.

[0014] As a further optimization of the present invention, a cabinet door is rotatably installed on the outer wall of the cabinet, a glass plate is fixedly embedded in the cabinet door, and a handle is fixedly installed on the outer wall of the cabinet door.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention incorporates a rack within the cabinet, which engages with a connecting strip at the bottom of the fixed frame. The connecting strip and the rack's different toothed grooves interlock, allowing for adjustment of the fixed frame's position. The mounting strip is installed by connecting it to the mounting groove of the fixed frame via a connector. By selecting different mounting grooves, the position of the mounting strip and the distance between adjacent mounting strips can be adjusted. This allows for the adaptation of electronic components of different specifications, facilitating their installation and improving space utilization.

[0017] 2. This invention uses a connecting frame set on the lower end face of the top plate, with a connecting groove in the connecting frame. The upper part of the cabinet is inserted into the connecting groove, and a snap-fit ​​component is set in the groove on the inner wall of the connecting groove. The snap-fit ​​component is used to realize the installation connection between the top plate and the cabinet. The end of the snap-fit ​​component is set as a hemispherical shape. The top plate can be directly removed by pulling it upward, which simplifies the installation, disassembly and cleaning of the top plate. The detachable top plate provides more space for cabinet maintenance and operation, and facilitates maintenance.

[0018] 3. This invention uses a drying box located in the lower part of the cabinet, containing a desiccant, to effectively dehumidify and ensure the dryness of the cabinet. Ventilation slots are set on both sides of the cabinet to ensure airflow and heat dissipation, preventing overheating and protecting electronic components from high-temperature risks. The mesh panels in the ventilation slots reduce the entry of dust and debris, and a shield is set on the outside of the cabinet to prevent rainwater from entering the cabinet through the ventilation slots, thus providing waterproofing.

[0026] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Example 1: As Figures 1-6As shown, an XL-type assembled power distribution cabinet includes a cabinet body 1. A top plate 22 is provided on the upper part of the cabinet body 1. A connecting frame 2 is fixedly installed on the lower end face of the top plate 22. A U-shaped connecting groove 3 is opened on the lower end face of the connecting frame 2. The upper wall of the cabinet body 1 is inserted into the connecting groove 3. A U-shaped fixing frame 4 is vertically slidably fitted on the inner wall of the cabinet body 1. The fixing frame 4 is connected to the cabinet body 1 through a plug-in mechanism. T-shaped mounting grooves 5 are opened at equal intervals on both side walls of the fixing frame 4. Mounting strips 6 are horizontally attached to the outer wall of the fixing frame 4. Mounting holes are evenly opened on the mounting strips 6. T-shaped connectors 7 are horizontally fixedly installed on the outer walls at both ends of the mounting strips 6. The connectors 7 movably pass through the mounting grooves 5. The mounting strips 6 are connected to the mounting grooves 5 of the fixing frame 4 through the connectors 7. Moving the mounting strips 6 upwards can pull the connectors 7 out of the mounting grooves 5 for quick disassembly of the mounting strips 6. The mounting strips 6 can be connected to mounting grooves 5 of different heights through the connectors 7, so that the position and spacing of multiple mounting strips 6 can be adapted to electronic components of different specifications.

[0028] like Figure 2 , Figure 3 As shown, the plug-in mechanism includes a rack 8 horizontally fixedly installed on the lower part of the inner wall on both sides of the cabinet 1, and plug-in strips 9 are fixedly installed on both ends of the lower end face of the fixing frame 4. The plug-in strips 9 are plugged into the grooves of the rack 8. The plug-in strips 9 can cooperate with different grooves of the rack 8 to adjust the position of the fixing frame 4, which facilitates the installation of electronic components.

[0029] like Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, a groove 10 is horizontally formed on the inner wall of the connecting groove 3. A snap-fit ​​component 11 is provided in the groove 10. The snap-fit ​​component 11 is fixedly connected to the inner wall of the groove 10 by a spring 12. A limit block 13 is provided at the end of the snap-fit ​​component 11 facing the groove 10. The limit block 13 slides with the inner wall of the groove 10. The end of the snap-fit ​​component 11 is hemispherical. The snap-fit ​​component 11 is movably embedded in the outer wall of the cabinet 1. The middle part of the connector 7 is cylindrical. The diameter of the cross section of the middle part of the connector 7 is the same as the width of the lower part of the mounting groove 5. The connector 7 slides with the outer wall of the fixing frame 4. The snap-fit ​​component 11 realizes the connection and fixation between the top plate 22 and the cabinet 1, which facilitates the disassembly of the top plate 22 and the disassembly and organization of the components inside the cabinet 1. The end of the snap-fit ​​component 11 is hemispherical, which can be directly released by applying force to facilitate the disassembly of the top plate 22. The limit block 13 limits the snap-fit ​​component 11 to prevent the snap-fit ​​component 11 from separating from the groove 10.

[0030] like Figure 1 , Figure 2As shown, multiple ventilation slots 14 are provided on both sides of the cabinet 1. A mesh plate 15 is fixedly installed inside the ventilation slot 14. A shielding component 16 that fits against the cabinet 1 is provided on the outside of the ventilation slot 14. Multiple shielding components 16 are fixedly connected by a connecting bracket 17. The connecting bracket 17 is fixedly connected to the cabinet 1 by screws. The ventilation slots 14 are set to assist heat dissipation and prevent the temperature inside the cabinet 1 from getting too high. The mesh plate 15 filters the air flowing inside and outside to prevent dust and debris from entering the cabinet 1. The shielding component 16 blocks rainwater to prevent rainwater from entering the cabinet 1 through the mesh plate 15.

[0031] like Figure 1 , Figure 2 As shown, multiple L-shaped limiting parts 18 are fixedly installed on the outer wall of the cabinet 1. The limiting parts 18 fit against the corner of the connecting frame 17. The limiting parts 18 are used to assist in the installation of the connecting frame 17, so that the threaded holes of the connecting frame 17 can be quickly aligned with the threaded holes on the outer wall of the cabinet 1, simplifying the installation.

[0032] like Figure 2 As shown, a placement frame 19 is fixedly installed on the bottom surface of the cabinet 1. A desiccant is placed on the bottom surface of the cabinet 1 and slides against the inner wall of the placement frame 19. The desiccant is placed in the desiccant to keep the inside of the cabinet 1 dry and prevent moisture.

[0033] like Figure 1 As shown, a cabinet door 21 is rotatably installed on the outer wall of the cabinet body 1. A glass plate is fixedly embedded in the cabinet door 21. A handle is fixedly installed on the outer wall of the cabinet door 21. The glass plate allows direct observation of the interior of the cabinet body 1, and the handle facilitates the opening of the cabinet door 21.

[0034] It should be noted that, in use, this XL-type assembled power distribution cabinet has a connecting frame 2 at the bottom of the top plate 22. The upper part of the cabinet body 1 is inserted into the connecting groove 3 of the connecting frame 2. The snap-fit ​​piece 11 in the connecting groove 3 is inserted and fixed to the outer wall of the cabinet body 1. When disassembling the top plate 22, the top plate 22 can be lifted upwards directly. The downward movement of the cabinet body 1 relative to the top plate 22 can push the snap-fit ​​piece 11 into the groove 10, causing the snap-fit ​​piece 11 to retract into the groove 10 against the force of the spring 12, thus canceling the snap-fit ​​piece 11 and completing the quick disassembly of the top plate 22. The mounting strip 6 is then lifted upwards, and the connecting piece 7 is pulled into the mounting strip 6. The mounting strip 6 moves upward synchronously to fit against the top surface of the mounting slot 5, and then pulls outward to remove the connector 7 from the mounting slot 5, thus separating and disassembling the mounting strip 6. The mounting strip 6 can be installed by connecting it to mounting slots 5 of different heights through the connector 7, allowing for height adjustment of the mounting strip 6 and adjustment of the distance between multiple mounting strips 6. The lower part of the fixed frame 4 is connected to the toothed groove of the rack 8 through the plug strip 9. By selecting different toothed grooves of the rack 8, the position of the fixed frame 4 can be adjusted. By adjusting the position of the fixed frame 4 and the position of the mounting strip 6, the space of the cabinet 1 can be rationally planned to facilitate the installation of electronic components of different specifications.

[0035] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
