It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] The following describes the specific implementation of the present utility model in detail in conjunction with specific embodiments.

[0027] Reference Figures 1 to 6 , a AC-DC power conversion structure provided by the present utility model includes: a box body 1 and a box cover 2. A conversion device is installed inside the box body 1. The output end and the input end of the conversion device are respectively connected to an output hole 6 and an input hole 17 through cables. The output hole 6 and the input hole 17 are respectively arranged on two end faces of the box body 1. A connecting ring 20 is provided on the inner wall of the box body 1. At both ends of the top of the connecting ring 20, a plurality of first connecting holes 24 and second connecting holes 21 are respectively provided. At both ends of the side of the box body 1, a first sliding hole 18 and a second sliding hole 19 are respectively provided. The first sliding hole 18 passes through a plurality of first connecting holes 24 from the side and penetrates to the other side of the box body 1 opposite to the side. The second sliding hole 19 passes through a plurality of second connecting holes 21 from the side and penetrates to the other side of the box body 1 opposite to the side. The first sliding hole 18 is slidably connected to a first baffle 25, and the second sliding hole 19 is slidably connected to a second baffle 26. The two ends of a stretching plate 4 are connected to the first baffle 25 and the second baffle 26.

[0028] An installation groove 15 is provided on the top of the box cover 2. A moving hole is provided at the bottom of the installation groove 15. A moving rod 3 is slidably connected to the moving hole. The side of the moving rod 3 is connected to a moving frame 29 through a connecting member 33. The bottom of the moving frame 29 is connected to a fixing plate 31 through a connecting rod 30. A return spring 16 is sleeved on the outer wall of the moving rod 3. One end of the return spring 16 is connected to the bottom end of the inner wall of the moving hole.

[0029] In an embodiment of the present utility model, as shown in reference Figure 4 , the first baffle 25 and the second baffle 26 have the same structure. The first baffle 25 includes a plate body 27. A plurality of notches 28 are provided on the top of the plate body 27. The length of the notches 28 is greater than the length of the first connecting holes 24.

[0030] It should be noted that when not in use, the first baffle 25 and the second baffle 26 move outward of the box body 1 driven by the stretching plate 4, so that the notches 28 of the first baffle 25 and the second baffle 26 are located inside the first connection hole 24 and the second connection hole 21. Then, by providing the moving rod 3 and the return spring 16, when the moving rod 3 is held and moved downward, the moving frame 29 can be driven to move downward, so that the fixing plates 31 on both sides respectively pass through the first connection hole 24 and the second connection hole 21 and are located below the first connection hole 24 and the second connection hole 21. Then, by moving the stretching plate 4, the first baffle 25 and the second baffle 26 are restored to their original positions, so that the notch 28 enters the first sliding hole 18 or the second sliding hole 19 between the first connection hole 24 or the second connection hole 21. Then, the moving rod 3 is released, and under the action of the return spring 16, the fixing plate 31 moves upward. However, due to the blockage of the first baffle 25 and the second baffle 26, the fixing plate 31 cannot continue to move upward. At this time, the box cover 2 is fixed above the connecting ring 20, and the connection between the box cover 2 and the box body 1 is completed. And with the above structure, the installation and disassembly of the box cover 2 can be completed without removing the screws, improving the work efficiency.

[0031] In an embodiment of the present invention, referring to Figure 1 、 Figure 3 As shown, the two ends of the stretching plate 4 are respectively provided with a first limiting hole 22 and a second limiting hole 23. The first limiting hole 22 and the second limiting hole 23 are respectively slidably connected to a first limiting shaft 9 and a second limiting shaft 12.

The two ends of the second limiting shaft 12 are respectively sleeved with a second front limiting plate 13 and a second rear limiting plate 14.

[0032] It should be noted that by providing the first limiting shaft 9 and the second limiting shaft 12, the positioning and limiting of the first baffle 25 and the second baffle 26 can be realized through the cooperation between the first front limiting plate 10 and the first rear limiting plate 11, and the second front limiting plate 13 and the second rear limiting plate 14. When moving, it can remind the user when the notch 28 is completely exposed.

[0033] In an embodiment of the present invention, referring to Figure 6 As shown, a connecting block 32 is provided at the top of the fixing plate 31. The bottoms of the first baffle 25 and the second baffle 26 are respectively provided with a plurality of first connection grooves 34 and second connection grooves 35 that cooperate with the connecting block 32.

[0034] It should be noted that by providing the connecting block 32, the first connection groove 34 and the second connection groove 35, the connection stability between the fixing plate 31 and the first baffle 25 and the second baffle 26 is improved.

[0035] In an embodiment of the present invention, referring to Figure 1As shown, at both ends of the inner wall of the box body 1, a first rotation hole and a second rotation hole are provided. The first rotation hole and the second rotation hole are respectively rotationally connected to a first limiting plate 7 and a second limiting plate 8. The first limiting plate 7 and the second limiting plate 8 are L-shaped.

[0036] It should be noted that: by providing the first limiting plate 7 and the second limiting plate 8, after the stretching plate 4 pushes the first baffle 25 and the second baffle 26 into the first sliding hole 18 and the second sliding hole 19, the two ends of the stretching plate 4 can be limited to prevent the stretching plate 4 from moving during use and affecting the fixation of the box cover 2.

[0037] In an embodiment of the present utility model, referring to Figure 1 As shown, a stretching ring 5 is vertically connected to the side of the stretching plate 4. The shape of the stretching ring 5 is U-shaped.

[0038] It should be noted that: by providing the stretching ring 5, it is convenient to hold the stretching ring 5 and move the stretching plate 4 back and forth, improving the convenience of using the device.

[0039] The working principle of an AC / DC power conversion structure provided by the present utility model is as follows:

[0040] By providing a moving rod 3 and a return spring 16, when holding the moving rod 3 and moving it downward, the moving frame 29 can be driven to move downward, so that the fixing plates 31 on both sides respectively pass through the first connection hole 24 and the second connection hole 21 and are located below the first connection hole 24 and the second connection hole 21. Then, by moving the stretching plate 4, the first baffle 25 and the second baffle 26 are restored to their original positions, so that the notch 28 enters the first sliding hole 18 or the second sliding hole 19 between the first connection hole 24 or the second connection hole 21. Then, release the moving rod 3. Under the action of the return spring 16, the fixing plate 31 moves upward. However, due to the blocking of the first baffle 25 and the second baffle 26, the fixing plate 31 cannot continue to move upward. At this time, the box cover 2 is fixed above the connecting ring 20, completing the connection between the box cover 2 and the box body 1. And for the above structure, the installation and disassembly of the box cover 2 can be completed without removing the screws, improving the work efficiency.

[0041] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated here too much.

[0042] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present utility model.
