[0027] This specific embodiment is a dimmable switching power supply, and its structural schematic diagram is shown below. Figures 1-8 As shown, the switching power supply includes a housing 1, a top cover 2 rotatably connected to the top of the housing 1, a side cover 3 rotatably connected to one end of the housing 1, and a limit mechanism is provided between the side cover 3 and the rectangular pull block 4.

[0028] The housing 1 has a power compartment 5 inside, and both sides of the power compartment 5 are provided with slidable transverse sliding seats 9. A movable transverse clamping plate 10 is provided at one end of the transverse sliding seat 9 near the power compartment 5. The housing 1 has a moving mechanism for moving the transverse sliding seats 9.

[0029] The moving mechanism includes a longitudinal rotating shaft 6. The longitudinal rotating shaft 6 is fixed inside the top cover 2. The longitudinal rotating shaft 6 is located inside the housing 1 and is rotatably connected to the housing 1 through bearings. Rectangular rotating plates 7 are fixed at both ends of the outer side of the longitudinal rotating shaft 6. A rectangular transmission plate 8 is rotatably connected to one side of the rectangular rotating plate 7 through a pin. A U-shaped longitudinal moving plate 11 is rotatably connected to the bottom of the rectangular transmission plate 8 through a pin. The U-shaped longitudinal moving plate 11 is located inside the housing 1 and is slidably connected to the housing 1. A transverse connecting plate 12 is fixed inside the U-shaped longitudinal moving plate 11. An oblique rotating plate 13 is rotatably connected to both ends of the transverse connecting plate 12 through a pin. A transverse sliding block 14 is rotatably connected to the end of the oblique rotating plate 13 away from the transverse connecting plate 12 through a pin. The top of the transverse sliding block 14 is fixedly connected to the transverse sliding seat 9.

[0030] A rectangular sliding groove is provided inside the housing 1. A U-shaped longitudinal moving plate 11 is located inside the rectangular sliding groove and is slidably connected to the housing 1 through the rectangular sliding groove. The rectangular sliding groove allows the U-shaped longitudinal moving plate 11 to slide longitudinally inside the housing 1. The movement of the U-shaped longitudinal moving plate 11 allows the transverse connecting plate 12 to move. The movement of the transverse connecting plate 12 allows the two transverse sliding blocks 14 to move through the oblique rotating plate 13.

[0031] The housing 1 has a transverse sliding groove inside. A vertical connecting block is fixed to the top of the transverse sliding block 14. The vertical connecting block is located inside the transverse sliding groove and is slidably connected to the housing 1 through the vertical sliding groove. Through the setting of the transverse sliding groove and the vertical connecting block, the transverse sliding block 14 can move inside the housing 1. The movement of the transverse sliding block 14 enables the transverse sliding seat 9 to move, thereby enabling the transverse clamping plate 10 to move.

[0032] Here, when the device needs to clamp the power compartment 5, the power compartment 5 is first placed inside the housing 1 and located between the two transverse clamping plates 10. Then, the top cover 2 is rotated downwards. The rotation of the top cover 2 allows the longitudinal rotating shaft 6 to rotate inside the housing 1. The rotation of the longitudinal rotating shaft 6 causes the U-shaped longitudinal moving plate 11 to slide inside the housing 1 through the rectangular rotating plate 7 and the rectangular transmission plate 8. The sliding of the U-shaped longitudinal moving plate 11 allows the transverse connecting plate 12 to move. The movement of the transverse connecting plate 12 causes the two transverse sliding blocks 14 to drive the transverse sliding seat 9 to move toward the power compartment 5 through the oblique rotating plate 13, thereby allowing the transverse clamping plate 10 to clamp the power compartment 5.

[0033] The moving mechanism also includes an internal hexagonal rotating component 15. The internal hexagonal rotating component 15 is rotatably connected to the interior of the transverse sliding seat 9 via a bearing. A first longitudinal threaded rod 16 is fixed to one side of the internal hexagonal rotating component 15, and a second longitudinal threaded rod 17 is fixed to one side of the first longitudinal threaded rod 16. The threads of the first longitudinal threaded rod 16 and the second longitudinal threaded rod 17 have opposite directions. Both the outer sides of the first longitudinal threaded rod 16 and the second longitudinal threaded rod 17 are threadedly connected to longitudinal sliding blocks 18. One end of the longitudinal sliding block 18 near the transverse clamping plate 10 is rotatably connected to an oblique rotating column 19 via a pin. The oblique rotating column 19 is located near the transverse clamping plate 10 and is rotatably connected to the transverse clamping plate 10 via a pin.

[0034] The interior of the transverse sliding seat 9 is provided with a rectangular through groove. The longitudinal sliding block 18 is located inside the rectangular through groove and is slidably connected to the transverse sliding seat 9 through the rectangular through groove. The rectangular through groove allows the longitudinal sliding block 18 to slide longitudinally inside the transverse sliding seat 9. The movement of the two longitudinal sliding blocks 18 is achieved by the oblique rotating column 19, which allows the transverse clamping plate 10 to move.

[0035] Here, when the top cover 2 is fully closed, and the transverse clamping plate 10 cannot clamp the power compartment 5, the hexagonal workpiece allows the internal hexagonal rotating part 15 to rotate. The rotation of the internal hexagonal rotating part 15 allows the first longitudinal threaded rod 16 to rotate, and the rotation of the first longitudinal threaded rod 16 allows the second longitudinal threaded rod 17 to rotate. The rotation directions of the first longitudinal threaded rod 16 and the second longitudinal threaded rod 17 are opposite, so that the movement directions of the two longitudinal sliding blocks 18 are opposite. The movement of the longitudinal sliding blocks 18 allows the transverse clamping plate 10 to move through the oblique rotating column 19, so that when the top cover 2 rotates to one side of the side cover 3, the two transverse clamping plates 10 can clamp the power compartment 5, preventing the power compartment 5 from shifting during operation.

[0036] The limiting mechanism includes a rectangular pull block 4. A rectangular pull block 4 is provided on the side of the side cover 3 away from the top cover 2. Both ends of the rectangular pull block 4 are fixed with longitudinal limiting rods 20. The longitudinal limiting rods 20 pass through the interior of the side cover 3 and are slidably connected to the side cover 3. A longitudinal rigid spring 21 is provided between the side cover 3 and the rectangular pull block 4 and on the outside of the longitudinal limiting rods 20. A circular limiting hole is provided inside the top cover 2 to fit the clearance of the top cover 2. The setting of the circular limiting hole allows the longitudinal limiting rods 20 to enter the interior of the top cover 2, thereby limiting the movement of the top cover 2 inside the side cover 3.

[0037] Here, when the top cover 2 and the side cover 3 need to be connected, the rectangular pull block 4 is pulled away from the side cover 3. The pulling of the rectangular pull block 4 allows the longitudinal limiting rod 20 to slide inside the side cover 3, thereby causing the longitudinal rigid spring 21 to be stretched. When the top cover 2 rotates to one side of the side cover 3, the pulling of the rectangular pull block 4 is released. Through the setting of the longitudinal rigid spring 21, the longitudinal limiting rod 20 can enter the interior of the top cover 2, thereby restricting the rotation of the top cover 2 and locking the transverse clamping plate 10 to restrict the power compartment 5.

[0038] The moving mechanism allows for the fixation of the power compartment 5. The adjustable horizontal clamping plate 10 can accommodate power compartments 5 of different sizes, improving versatility. The boltless fixing method facilitates the quick installation and disassembly of the power compartment 5, improving maintenance efficiency and ensuring good stability of the power compartment 5 after fixing.

[0039] Working principle: When using the switching power supply of this technical solution, when the device needs to clamp the power compartment 5, first place the power compartment 5 inside the housing 1 and between the two transverse clamping plates 10, then rotate the top cover 2 downwards. The rotation of the top cover 2 allows the longitudinal rotating shaft 6 to rotate inside the housing 1. The rotation of the longitudinal rotating shaft 6 causes the U-shaped longitudinal moving plate 11 to slide inside the housing 1 through the rectangular rotating plate 7 and the rectangular transmission plate 8. The sliding of the U-shaped longitudinal moving plate 11 allows the transverse connecting plate 12 to move. The movement of the transverse connecting plate 12 causes the two transverse sliding blocks 14 to drive the transverse sliding seat 9 to move toward the power compartment 5 through the oblique rotating plate 13, thereby allowing the transverse clamping plate 10 to clamp the power compartment 5.

[0040] When the top cover 2 is fully closed, and the transverse clamping plate 10 cannot clamp the power compartment 5, the hexagonal workpiece allows the internal hexagonal rotating part 15 to rotate. The rotation of the internal hexagonal rotating part 15 allows the first longitudinal threaded rod 16 to rotate, and the rotation of the first longitudinal threaded rod 16 allows the second longitudinal threaded rod 17 to rotate. The rotation directions of the first longitudinal threaded rod 16 and the second longitudinal threaded rod 17 are opposite, causing the two longitudinal sliding blocks 18 to move in opposite directions. The movement of the longitudinal sliding blocks 18 causes the transverse clamping plate 10 to move through the oblique rotating column 19, so that when the top cover 2 rotates to one side of the side cover 3, the two transverse clamping plates 10 can clamp the power compartment 5, preventing the power compartment 5 from shifting during operation.

[0041] When the top cover 2 and the side cover 3 need to be connected, the rectangular pull block 4 is pulled away from the side cover 3. The pulling of the rectangular pull block 4 allows the longitudinal limiting rod 20 to slide inside the side cover 3, thereby causing the longitudinal rigid spring 21 to be stretched. When the top cover 2 rotates to one side of the side cover 3, the pulling of the rectangular pull block 4 is released. Through the setting of the longitudinal rigid spring 21, the longitudinal limiting rod 20 can enter the interior of the top cover 2, thereby restricting the rotation of the top cover 2 and locking the transverse clamping plate 10 to restrict the power compartment 5.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
