Description

Technical Field

[0001] This utility model relates to the field of high-frequency switching power supply technology, and in particular to a quick-assembly and disassembly high-frequency switching power supply box. Background Technology

[0002] High-frequency switching power supplies, as common power supply equipment, are widely used in various fields such as industrial production, communication base stations, and new energy. Therefore, the market demand for high-frequency switching power supplies is enormous. In the production of high-frequency switching power supply boxes, sheet metal processing is typically used to form each wall panel separately, which is then assembled using screw riveting or welding. However, in actual production and use, due to the numerous fixing points, the screw tightening and welding processes are quite cumbersome. Furthermore, issues such as misaligned screws or misaligned housings during welding can easily occur, negatively impacting the appearance of the power supply box. This connection method also makes disassembling the power supply box for maintenance and repair cumbersome, affecting maintenance efficiency. Additionally, since high-frequency switching power supply boxes are generally placed in electrical cabinets, stability is crucial during placement. Conventional power supply boxes can only be secured using internal fixing mechanisms, which can easily lead to incompatibility if the power supply box model changes, significantly reducing its adaptability.

[0003] Therefore, considering the aforementioned technical problems, it is necessary to provide a new technical solution. Utility Model Content

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] Example

[0023] Please see Figures 1 to 3 A quick-assembly and disassembly high-frequency switching power supply box includes a box body 1 and a clamping mechanism 2 mounted on the box body. The clamping mechanism includes a clamping arm 23, which is provided with a retractable tension gripper 231 and a return spring 232 for controlling the resetting of the tension gripper. The box body 1 includes three side plates 11 located at the rear and left and right sides of the box body and end plates 12 located at the lower ends of the box body. The three side plates are integrally bent and formed, and the connection between the side plates and the end plates is provided with mutually adaptable flanges 14.

[0024] The flange 14 has a hook-shaped cross section, and the flanges of the side plate and the end plate are slidably hooked together.

[0025] The enclosure 1 also includes a cover plate 13 located at the front of the enclosure. Magnetic strips are provided around the perimeter of one side of the cover plate near the side plate and the end plate. The cover plate is magnetically connected to the side plate and the end plate through the magnetic strips.

[0026] The housing 1 is provided with at least one pair of fixing seats 15. The fixing seats are fixedly installed at one end of the side plate near the cover plate. At least one limiting post 16 is fixedly installed on each fixing seat. Each pair of fixing seats is asymmetrically arranged along the center of the housing. The cover plate is provided with limiting holes that are adapted to the limiting posts.

[0027] The clamping mechanism 2 also includes a slide rail 21 fixed on the side plate 11 and a lockable sliding seat 22 slidably mounted on the slide rail, and the clamping arm 23 is mounted on the sliding seat.

[0028] The slide rails 21 and sliding seats 22 are multiple in number, and each slide rail and sliding seat is installed on the three side plates respectively.

[0029] The sliding seat 22 is circular or square, and multiple fixing holes 221 are evenly arranged around the center of the sliding seat. One end of the clamping arm is locked to the sliding seat by bolts through the fixing holes. The direction of the sliding seat can be adjusted by rotating it at a fixed angle according to the number of fixing holes, thereby adjusting the clamping direction of the jaws to clamp beams and columns at various angles in the electrical cabinet.

[0030] In this embodiment of the high-frequency switching power supply box, during assembly, the hook-shaped flange forms a strip-shaped slot. Simply align the flanges of the upper and lower end plates with the flanges of the side plates and push the end plates into place. Then, align the limiting holes on the cover plate with the limiting posts to fix the cover plate magnetically. In use, place the power supply box in the electrical cabinet. Since there are many beams and columns in the electrical cabinet, simply move the clamping arms and adjust their angles according to the actual arrangement of the beams and columns in the electrical cabinet. Use the tensioning jaws to hold the beams or columns to complete the stable installation of the power supply box. Similarly, during disassembly, simply loosen the tensioning jaws and pull out the end plates.

[0031] The beneficial effects of this utility model are: by replacing conventional welding or bolt fastening with a simple but stable connection method, the various wall panels of the power supply box can be assembled by simple pushing, pulling and fitting, etc. The overall operation steps are simpler and more efficient, and disassembly and reassembly during maintenance will not affect its structural stability, making it more convenient to use. At the same time, the clamping mechanism added to the outside of the box can install and fix the power supply box according to the actual layout of the electrical cabinet in which the power supply box is located, making it more adaptable to the space size inside the electrical cabinet and more stable and less prone to shaking.

[0032] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications and variations to the above embodiments within the scope of the present invention.
