Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0036] According to one embodiment of the present invention, in conjunction with Figures 1-4 As shown. A DC-DC switching power supply module structure includes a power supply module body 1, a fixing pad 2 fixed to the bottom of the power supply module body 1, a top cover plate 3 provided on the top of the power supply module body 1, a line reinforcement mechanism 4 installed on the outside of the power supply module body 1, and an auxiliary maintenance mechanism 5 provided on the outside of the power supply module body 1;

[0037] The line reinforcement mechanism 4 includes a fixing plate 41. A lower protective sleeve 42 is fixed to the top of the fixing plate 41. An upper protective sleeve 43 is rotatably connected to the top of the lower protective sleeve 42 via a rotating shaft. A lower reinforcing sleeve 44 is fixed to the inner wall of the lower protective sleeve 42. An upper reinforcing sleeve 45 is fixed to the inner wall of the upper protective sleeve 43. A metal plate 46 is fixed to one side of the lower protective sleeve 42. A limit sleeve 47 is fixed to the outer side of the upper protective sleeve 43. A supporting threaded rod 48 is fixed to the top of the metal plate 46. A limit nut 49 is threadedly connected to the outer side of the supporting threaded rod 48. A limit groove is formed inside the limit sleeve 47. The size of the limit groove is the same as the size of the supporting threaded rod 48. The adapter serves to limit the position of the supporting threaded rod 48. The fixing plate 41 is fixedly connected to the power module body 1, and the lower protective sleeve 42 is fixedly connected to the power module body 1, which can ensure the stable connection between the lower protective sleeve 42 and the power module body 1. The corresponding surface of the upper protective sleeve 43 fits with the corresponding surface of the lower protective sleeve 42, and the corresponding surfaces of the upper reinforcing sleeve 45 and the lower reinforcing sleeve 44 fit together. By adopting the above technical solution, the upper protective sleeve 43 and the lower protective sleeve 42 can fit tightly together, and the lower protective sleeve 42 and the lower reinforcing sleeve 44 can be bonded and fixed together. The outer side of the limiting nut 49 is provided with anti-slip texture to enhance the friction when manually tightening.

[0038] The auxiliary maintenance mechanism 5 includes a maintenance access door 51, a reinforcing pad 52 fixed to the top of the maintenance access door 51, a reinforcing threaded post 53 fixed to the outside of the reinforcing pad 52, a reinforcing nut 54 threadedly connected to the outside of the reinforcing threaded post 53, an anti-detachment guide sleeve 55 fixed to the outside of the power module body 1, an anti-detachment slider 56 slidably connected to the outside of the anti-detachment guide sleeve 55 via a slide groove, a reinforcing plate 57 fixed to the outside of the anti-detachment slider 56, a handle pad 58 fixed to the outside of the reinforcing plate 57, the maintenance access door 51 and the power module body 1 are hinged together by a hinge, and the reinforcing plate 57 is movably sleeved on the outside of the reinforcing threaded post 53.

[0039] In this embodiment, after the corresponding line is connected to the power module body 1, the upper protective sleeve 43 is rotated, allowing the limiting sleeve 47 on the outer side of the upper protective sleeve 43 to movably engage with the outer side of the supporting threaded rod 48. Then, the limiting nut 49 is threadedly connected to the supporting threaded rod 48, ensuring that the inner walls of the lower reinforcing sleeve 44 and the upper reinforcing sleeve 45 are tightly fitted to the outer side of the line. This effectively reduces interface loosening caused by external forces, avoids accidental power outages or poor contact, significantly improves the reliability and safety of the power interface of the power module body 1, and the reinforced design reduces the burden of daily inspections. This device is designed for scenarios where frequent maintenance is difficult. With an auxiliary maintenance mechanism 5, when the maintenance door 51 needs to be opened for internal maintenance of the power module body 1, the user can rotate the reinforcing nut 54 on the outside of the reinforcing threaded post 53. After unscrewing the reinforcing nut 54, the user can move the handle pad 58 to move the reinforcing plate 57 and the anti-detachment slider 56. This releases the restriction of the reinforcing plate 57 on the reinforcing pad 52, allowing the user to easily open the maintenance door 51 and perform internal maintenance on the power module body 1, thus simplifying internal maintenance.

[0040] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
