Description

Technical Field

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

[0002] A cabinet power supply is a power device used for lighting inside cabinets. It provides power to LED lights or other types of lighting fixtures installed inside the cabinet. This type of power supply is typically designed for low-voltage output, such as 12V or 24V, to ensure safety and energy efficiency. Cabinet power supplies may include components such as switching power supplies, constant-voltage drive adapters, and transformers; these can be built-in or external, depending on design and installation requirements.

[0003] The existing cabinet power supply devices have the following disadvantages: 1. Cabinet power supply devices are usually embedded in the mounting holes, which makes the installation unstable and unreliable. Using screws for reinforcement is inconvenient for arranging the mounting screws and cannot cover them, affecting the overall aesthetics; 2. In the existing structure, it is inconvenient to disassemble the various parts of the cabinet power supply device, making maintenance inconvenient.

[0004] Therefore, how to provide a cabinet power supply device with a simpler and more reasonable structural design, which makes it easier to install and arrange mounting screws, improves installation stability, and makes it easier to disassemble each part of the device has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this utility model is how to provide a cabinet power supply device with a simpler and more reasonable structural design, which can facilitate the installation and arrangement of mounting screws, improve installation stability, and make it easier to disassemble each part of the device.

[0006] To achieve the above objectives, this utility model provides a cabinet power supply device, including a device body. The device body includes an outer shell with an overall circular box structure. An electrical plug-in structure is provided inside the outer shell. On one surface of the outer shell, each corresponding to an electrical plug-in structure, has a recessed opening for a plug to be inserted into the plug-in interface. The device is characterized by having multiple mounting holes evenly arranged circumferentially along the edge of another surface of the outer shell, each used for mounting screws. The mounting holes are arranged at an angle, with the distal end of the mounting hole angled outwards and penetrating the outer circumference of the outer shell. Each mounting hole includes a front section and a rear section, with the diameter of the front section being larger than the diameter of the rear section. The inner diameter of the front section matches the head diameter of the mounting screw, and the diameter of the rear section matches the threaded shank diameter of the mounting screw.

[0007] Thus, during installation, the aforementioned cabinet power supply device involves first creating a through hole in the cabinet, then embedding the outer casing into the through hole, and finally placing mounting screws inside the mounting hole. These screws pass through the mounting hole and are threaded onto the inner wall of the through hole; self-tapping screws can be used here. This structural design is simpler, facilitates the placement of mounting screws, and makes the entire device more stable and reliable after installation.

[0008] As an optimization, the mounting holes are two that are evenly distributed along the circumference.

[0009] This makes the number of mounting holes more reasonable.

[0010] As an optimization, the housing includes a circular box structure with an open side, and the plug-in part structure is provided inside the housing; the mounting hole is provided on the edge of the side surface of the housing opposite to the open side, and the distal end of the mounting hole extends through the outer peripheral surface of the housing; a raised edge plate is provided on the outer peripheral surface of the side surface of the housing opposite to the open side, and the surface of the raised edge plate is flush with the surface of the housing; a panel is attached to the outer surface of the raised edge plate, and a snap-fit ​​structure is provided between the panel and the raised edge plate to detachably snap-fit ​​the panel onto the raised edge plate.

[0011] In this way, the mounting holes can be better concealed by the panel, making the overall structure more aesthetically pleasing. Secondly, the panel is removable, making the structural design more rational and easier to assemble and disassemble.

[0012] As an optimization, an inclined connecting block is provided between the bottom surface of the inner shell and the inner peripheral wall, and the mounting hole is provided through the connecting block.

[0013] In this way, by setting up connecting blocks, it is easier to lay out and set up the mounting holes, and the structural strength of the mounting holes can be improved.

[0014] Furthermore, the connecting block and the shell are integrally formed.

[0015] As an optimization, the snap-fit ​​structure includes a ring-shaped flange formed by bending the edge of the panel, such that the flange fits over the outside of the raised edge plate; multiple inwardly protruding snap-fit ​​protrusions are evenly arranged on the inner circumferential surface of the distal end of the flange along the circumferential direction; a snap-fit ​​notch is provided on the raised edge plate at a position corresponding to the snap-fit ​​protrusions; a long strip-shaped and curved arc-shaped snap groove is provided on the inner surface of the raised edge plate at a position opposite to one end of the snap-fit ​​notch, such that the side of the snap groove opposite to the inner circumferential wall of the flange and the end opposite to the snap-fit ​​notch are each open; and after the panel is rotated relative to the raised edge plate at a certain angle, the snap-fit ​​protrusions can be supported against the bottom surface inside the snap groove.

[0016] This makes the snap-fit ​​structure design simpler and more reasonable, and makes it easier to assemble and disassemble the panel.

[0017] Furthermore, a chamfered structure is provided on the bottom surface of the card slot at the end opposite to the card engagement notch.

[0018] Furthermore, the far end face of the flange is flush with the inner side of the protruding plate.

[0019] Furthermore, two mounting rotation marks are provided in pairs at the edge of the outer surface of the panel.

[0020] As an optimization, the housing also includes a cover that is detachably snapped onto the open end of the housing via a snap-fit ​​structure, and the cover is provided with the clearance opening.

[0021] This makes the outer casing design simpler and allows for easier disassembly and assembly of the cover, thus facilitating maintenance.

[0022] As an optimization, the shell cover includes a shell cover plate with a circular structure. The edge of the shell cover plate is bent toward the shell to form a ring-shaped mating sleeve and is inserted into the open end of the shell. The snap-fit ​​structure includes snap-fit ​​holes that are evenly distributed along the circumference on the mating sleeve and are arranged to penetrate the thickness direction of the mating sleeve. On the inner circumferential surface of the shell, snap-fit ​​blocks are provided corresponding to the snap-fit ​​holes and are snapped into the snap-fit ​​holes.

[0023] This makes it easier to connect and install the cover with the housing, and the snap-fit ​​structure is simple and reasonable, which can improve the reliability of installation.

[0024] Furthermore, the buckle holes are four that are evenly distributed along the circumference.

[0025] In summary, the aforementioned cabinet power supply device features a simpler and more reasonable structural design, easier installation and placement of mounting screws, improved installation stability, and easier disassembly of each part of the device. Attached Figure Description

[0040] In this way, the mounting holes can be better concealed by the panel, making the overall structure more aesthetically pleasing. Secondly, the panel is removable, making the structural design more rational and easier to assemble and disassemble.

[0041] In this specific embodiment, an inclined connecting block 10 is provided between the bottom surface of the inner shell and the inner peripheral wall, and the mounting hole is provided through the connecting block.

[0042] In this way, by setting up connecting blocks, it is easier to lay out and set up the mounting holes, and the structural strength of the mounting holes can be improved.

[0043] Furthermore, the connecting block and the shell are integrally formed.

[0044] In this specific embodiment, the snap-fit ​​structure includes a ring-shaped flange 11 formed by bending the edge of the panel, such that the flange fits over the outside of the convex edge plate; a plurality of snap-fit ​​protrusions 12 are evenly arranged on the inner circumferential surface of the distal end of the flange along the circumferential direction; a snap-fit ​​notch 13 is provided on the convex edge plate at a position corresponding to the snap-fit ​​protrusions; a slot 14 with a long strip structure and an arc-shaped structure is provided on the inner surface of the convex edge plate at a position opposite to one end of the snap-fit ​​notch, such that the side of the slot opposite to the inner circumferential wall of the flange and the end opposite to the snap-fit ​​notch are each open; and after the panel is rotated relative to the convex edge plate by a certain angle, the snap-fit ​​protrusions can be supported against the bottom surface inside the slot.
