[0031] 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.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of a modular installation structure for a switching power supply, including a base 1 for supporting a housing 3 and for installation in a device, facilitating the installation of the switching power supply. A mounting component 2 is provided on the lower side of the base 1, which can be fixed to the base 1 and the device by bolts. A housing 3 is provided on the upper part of the base 1 to protect the internal switching power supply body 5 from external impacts, dust, etc. Holes are provided through the outer side of the housing 3 to aid heat dissipation and reduce overall weight. In high-temperature environments, the holes effectively dissipate heat, ensuring stable operation of the switching power supply. The inner wall of the base 1 is provided with an installation mechanism, which includes a connecting component and an installation component. The connecting component includes two sets of limiting strips 41, which can limit the outer shell 3 and the movable plate 43. The limiting strips 41 are fixedly connected to the outer side of the base 1. A limiting groove 49 is opened on the outer side of the limiting strip 41, which cooperates with the limiting component 45 to fix the outer shell 3 and the movable plate 43, realizing modular installation. A slot 42 is opened on the outer side of the outer shell 3, which slides with the limiting strip 41. During the installation process, the slot 42 slides along the limiting strip 41, guiding the outer shell 3 to be accurately installed on the base 1, ensuring the accuracy and stability of the installation.

[0033] Reference Figure 3 - Figure 5 The slot 42 slides on the outside of the limiting strip 41. A movable plate 43 is inserted into the inner wall of the outer casing 3 to support and position the switching power supply body 5, so that the switching power supply body 5 can be stably installed inside the outer casing 3. The upper part of the movable plate 43 is fixedly connected to the switching power supply body 5 to realize the power conversion and supply function and provide stable power support for other devices. A fixing block 44 is fixedly connected to the right side of the movable plate 43 to provide an installation position for the limiting member 45 and the pressing rod 48. The inner wall of the fixing block 44 is slidably connected to the limiting member 45. 5. The limiting member 45 is inserted into the inner wall of the limiting groove 49. There are two sets of limiting members 45, which are inserted into the inner wall of the limiting groove 49 to lock the relative position of the outer shell 3, the moving plate 43 and the base 1, prevent the outer shell 3 and the moving plate 43 from detaching from the base 1, and ensure that the switching power supply body 5 is installed firmly. The two sets of limiting members 45 are elastically connected by compression springs 46, which provide elastic force to the limiting members 45 so that they can always maintain the tendency to be inserted into the limiting groove 49, ensuring that the limiting members 45 and the limiting groove 49 are tightly fitted, and enhancing the stability of the installation.

[0034] Furthermore, the mounting assembly includes a guide groove 47, which slides in conjunction with a pressing rod 48. The inclined surface of the inner wall of the guide groove 47 interacts with the lower inclined surface of the pressing rod 48. When the pressing rod 48 is pressed, the guide limiting member 45 retracts, enabling the disassembly of the power supply body 5. The guide groove 47 is located on the upper inner wall of the limiting member 45, and the pressing rod 48 is slidably connected to the inner wall of the guide groove 47. Both the inner wall of the guide groove 47 and the lower part of the pressing rod 48 are inclined surfaces. By pressing the pressing rod 48, its engagement with the inclined surface of the guide groove 47 pushes the limiting member 45 to retract, facilitating the disassembly of the power supply body 5 during equipment maintenance or upgrades. The operation is simple and convenient. The pressing rod 48 is slidably connected to the inner wall of the fixing block 44. The pressing rod 48 is U-shaped, and the upper part of the pressing rod 48 bends to the right, making it easy for the operator to press the pressing rod 48.

[0035] Reference Figure 6 The right side of the limiting strip 41 is set as an arc surface, and the left side of the limiting member 45 near the limiting strip 41 is set as an inclined surface. During installation, it cooperates with the arc surface of the limiting strip 41 to facilitate the compression of the limiting member 45 to shrink it, thus achieving quick installation. An auxiliary component is set on the left side of the outer shell 3. The auxiliary component includes a rubber pad 61, which is fixedly connected to the inner wall of the outer shell 3. The rubber pad 61 is made of rubber to increase the friction between the connection line and the switching power supply body 5, thereby helping to fix the line, preventing the line from loosening, and improving the stability of the equipment operation. A cross groove 62 is opened through the surface of the rubber pad 61 to enhance the buffering effect, reduce the impact of vibration on the switching power supply, further protect the switching power supply body 5, and ensure that it can work normally in a vibration environment. Two sets of rubber pads 61 are provided.

[0036] Working principle: In use, first fix the switching power supply body 5 on the moving plate 43, then insert the moving plate 43 into the inner wall of the outer shell 3. When installing the outer shell 3, the slot 42 on the outer side of the outer shell 3 is aligned with the limiting strip 41 on the outer side of the base 1 and slides. Since the right side of the limiting strip 41 is an arc surface and the left side of the limiting member 45 near the limiting strip 41 is an inclined surface, the two press against each other, causing the two sets of limiting members 45 to contract under the action of the compression spring 46. When the outer shell 3 moves to the appropriate position, the limiting member 45 is inserted into the limiting groove 49 on the outer side of the limiting strip 41 under the elastic force of the compression spring 46, completing the installation of the outer shell 3, the moving plate 43 and the base 1, realizing the quick installation and fixation of the switching power supply body 5.

[0037] The rubber pad 61 on the left side of the outer casing 3 contacts the connecting circuit. The rubber material increases friction and helps to fix the circuit. The cross groove 62 on the surface of the rubber pad 61 can buffer vibration and reduce its impact on the switching power supply body 5, further ensuring the stability of equipment operation.

[0038] When maintenance or replacement of the switching power supply body 5 is required, press the pressing rod 48. The pressing rod 48 slides on the inner wall of the fixing block 44. Its lower inclined surface interacts with the inclined surface of the guide groove 47 on the upper inner wall of the limiting member 45, pushing the limiting member 45 to overcome the elastic force of the compression spring 46 and contract, so that the limiting member 45 is disengaged from the limiting groove 49. At this time, the outer shell 3 can be removed from the base 1, and the switching power supply body 5 can be easily disassembled.

[0039] 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.
