[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The technical solution in the embodiment of the present application effectively solves the technical problem that the screws are troublesome to disassemble and assemble, and increases the difficulty of maintenance work. The overall idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides a dimmable high-power constant-current driven LED power supply, which includes a power supply body 1, connecting plates 2 are provided at both ends of the power supply body 1, connecting blocks 3 are fixedly installed at both ends of the power supply body 1, each connecting block 3 is provided with a slide groove 4 on the outside, each slide groove 4 is fixedly connected with a spring 5 on the inside, each spring 5 is fixedly connected with a limiting block 6 on the outside, and the limiting block 6 is slidably connected to the inside of the slide groove 4, and each of the connecting plates 2 is provided with a connecting mechanism on the outside, and each connecting mechanism includes a groove 7, a rotating shaft 8, a mounting frame 9 and a limiting hole 10, the groove 7 is provided on the outside of the connecting plate 2, the rotating shaft 8 is rotatably connected to the inside of the groove 7, both ends of the mounting frame 9 are provided on the outside of the rotating shaft 8, the limiting hole 10 is provided on the outside of the mounting frame 9, and the connecting block 3 is slidably connected to the mounting plate 2. On the inner side of the frame 9, the limit block 6 is slidably connected to the inside of the limit hole 10. By setting the limit block 6 and cooperating with the limit hole 10, when repairing the power supply, the limit block 6 is pressed to release the connection between the limit block 6 and the limit hole. At this time, the mounting frame 9 is rotated toward the groove 7 so that the mounting frame 9 is no longer directly above the connecting block 3. At this time, the limit block 6 can be loosened. At this time, the power supply body 1 is pulled upward so that the power supply body 1 is no longer between the two connecting plates 2. At this time, the power supply body 1 is disassembled. When the maintenance is completed, the power supply body 1 is placed between the two connecting plates 2, and the mounting frame 9 is rotated upward. When the mounting frame 9 is blocked by the limit block 6, the limit block 6 is pressed downward until the mounting frame 9 can continue to rotate. When the mounting frame 9 is erected, the limit block 6 is loosened to allow the limit block 6 to enter the inside of the limit hole 10. At this time, the power supply body 1 is installed. There is no need to release the screw fixation when repairing the power supply, which reduces the difficulty of maintenance work.

[0028] Each chute 4 has a built-in groove 11 inside, and each built-in groove 11 is slidably connected with a built-in plate 12 , which is fixedly mounted on the outside of the limit block 6 to prevent the limit block 6 from being disconnected from the chute 4 .

[0029] Both ends of each connecting plate 2 are provided with openings 13, which are communicated with the groove 7. The rotating shaft 8 is movably connected to the inside of the opening 13, which is a structure for the rotating shaft 8 to rotate. Both ends of each mounting bracket 9 are provided with connecting holes 14, and the mounting bracket 9 is sleeved on the outside of the rotating shaft 8 through the connecting holes 14, which is convenient for releasing the connection between the mounting bracket 9 and the rotating shaft 8. The outside of each rotating shaft 8 is provided with a baffle 15, and the outside of each rotating shaft 8 is provided with an external thread 16. The baffle 15 is threadedly connected to the outside of the external thread 16, which is convenient for limiting the movement of the rotating shaft 8. By providing the baffle 15 and cooperating with the opening 13, the baffle 15 is rotated to release the connection between the baffle 15 and the external thread 16. At this time, the rotating shaft 8 is pulled to release the connection between the rotating shaft 8 and the connecting hole 14 and the opening 13. At this time, the mounting bracket 9 is pulled upward to release the connection between the limit block 6 and the limit hole 10. At this time, the power supply body 1 can be pulled upward to disassemble the power supply body 1, which adds another disassembly method for the power supply to provide a backup plan for the staff when the first disassembly method fails.

[0030] Short plates 17 are fixedly installed at both ends of the power supply body 1, and a limiting plate 18 is fixedly installed on the outside of each connecting plate 2. The limiting plate 18 is attached to the outside of the short plate 17 to facilitate limiting the position of the power supply body 1 so that the limiting block 6 enters the inner side of the mounting frame 9 when the power supply body 1 is installed.

[0031] Working principle:

[0032] By setting the limit block 6 and cooperating with the limit hole 10, when the power supply is repaired, the limit block 6 is pressed to release the connection between the limit block 6 and the limit hole, and the mounting bracket 9 is rotated toward the groove 7 so that the mounting bracket 9 is no longer located directly above the connecting block 3. At this time, the limit block 6 can be loosened, and the power supply body 1 is pulled upward so that the power supply body 1 is no longer located between the two connecting plates 2. At this time, the power supply body 1 is disassembled;

[0033] In the second step, after the maintenance is completed, the power supply body 1 is placed between the two connecting plates 2. When placing the power supply body 1, the short plate 17 is attached to the outside of the limit plate 18. At this time, the mounting frame 9 is rotated upward. When the mounting frame 9 is blocked by the limit block 6, the limit block 6 is pressed downward until the mounting frame 9 can continue to rotate. When the mounting frame 9 is erected, the limit block 6 is released to allow the limit block 6 to enter the inside of the limit hole 10. At this time, the power supply body 1 is installed.

[0034] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
