[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] Please see Figs. 1-4 In this embodiment of the present invention, a circuit board assembly structure for an LED power supply includes an LED power supply circuit board body 1. Fixing rings 4 are installed at each of the four corners of the LED power supply circuit board body 1. Fixing cylinders 5 are fixed at each of the four corners of the lower surface of the LED power supply circuit board body 1 outside the fixing rings 4. Movable cylinders 6 are slidably installed on the inner side of each fixing cylinder 5 in a vertical direction. Bolts 11 are inserted vertically between the inner side of each fixing ring 4 and the inner side of the corresponding movable cylinder 6. A first heat sink 2 is fixed on the lower surface of the LED power supply circuit board body 1 outside the fixing cylinders 5. Several second heat sinks 3 are fixed at horizontal intervals in the middle of the lower surface of the first heat sink 2. This allows for convenient adjustment of the height of the LED power supply circuit board body 1 assembled into the LED power supply, facilitating different heights of assembly and height adjustment according to the required usage of the LED power supply circuit board body 1. This helps ensure the heat dissipation efficiency of the LED power supply circuit board body 1 during use, thus facilitating its use.

[0033] The LED power circuit board body 1 has a matching first retention hole 12 corresponding to the fixing ring 4. The first retention hole 12 penetrates the upper surface and outer surface of the corresponding position on the LED power circuit board body 1. The fixing ring 4 helps to limit the bolt 11 and facilitates stable use of the bolt 11. The outer ring surface of the fixing ring 4 is in a matching fit with the inner ring surface of the corresponding first retention hole 12 on the LED power circuit board body 1. The fixing ring 4 is fixedly connected to the corresponding first retention hole 12 on the LED power circuit board body 1. The first retention hole 12 on the LED power circuit board body 1 helps to limit the fixing ring 4.

[0034] Springs 9 are fixed to the lower surface of the fixed ring 4. The springs 9 are all in a vertical state. The lower end of the springs 9 is fixedly connected to the upper surface of the corresponding moving cylinder 6. The springs 9 help to connect and limit the fixed ring 4 and the moving cylinder 6. The first heat dissipation plate 2 is in a horizontal state. The four corners of the first heat dissipation plate 2 are provided with matching second retention holes 13 corresponding to the fixed cylinder 5. The second retention holes 13 penetrate the upper and lower surfaces of the first heat dissipation plate 2 at the corresponding positions. The second retention holes 13 on the first heat dissipation plate 2 help to limit the fixed cylinder 5.

[0035] All fixed cylinders 5 are vertical, and the inner ring surface of each fixed cylinder 5 is in a matching and fitting state with the outer ring surface of the corresponding movable cylinder 6. The fixed cylinder 5 helps to limit the movable cylinder 6 and facilitates its use. All four sides of the outer ring surface of the movable cylinder 6 are fixed with locking blocks 8, and all four sides of the inner ring surface of the fixed cylinder 5 are provided with matching locking grooves 7 corresponding to the locking blocks 8. The locking grooves 7 and locking blocks 8 facilitate the positioning between the fixed cylinder 5 and the movable cylinder 6. All movable cylinders 6 are vertical, and the lower end surface of each movable cylinder 6 is fixed with a matching and fitting annular pad 10. The movable cylinder 6 can fix and limit the annular pad 10, which helps to stabilize the use of the annular pad 10.

[0036] The working principle of this utility model is as follows: During use, the lower surface of the annular pad 10 is aligned with the position to be installed on the external LED power supply. The LED power supply circuit board body 1 is then pressed downwards, so that the LED power supply circuit board body 1 is located at the height to be assembled inside the LED power supply. When the LED power supply circuit board body 1 is aligned with different heights on the external LED power supply, the annular pad 10 will drive the moving cylinder 6 to move vertically along the fixed cylinder 5. The moving cylinder 6 can drive the locking block 8 to move along the slot 7 on the fixed cylinder 5. The fixed cylinder 5 can limit the moving cylinder 6 through the slot 7 and the locking block 8, which helps to move the moving cylinder 6 stably.

[0037] After the bolt 11 passes through the fixing ring 4 and the moving cylinder 6, it is threaded into the corresponding position on the external LED power supply. The external LED power supply can fix and limit the LED power supply circuit board body 1 and the various components assembled on the LED power supply circuit board body 1 through the bolt 11. The annular pad 10 facilitates the limitation between the moving cylinder 6 and the external LED power supply. The moving cylinder 6 can support and limit the fixing ring 4 and the LED power supply circuit board body 1 through the spring 9, which facilitates the stable use of the fixing ring 4 and the LED power supply circuit board body 1 and helps to assemble the LED power supply circuit board body 1 with the external LED power supply.

[0038] By moving the movable cylinder 6 vertically within the fixed cylinder 5, and with the spring 9 supporting the fixed ring 4 and the LED power circuit board body 1, a suitable gap can be maintained between the first heat sink 2 and the second heat sink 3 and the external LED power supply. When the LED power circuit board body 1 is in use, the heat generated on the LED power circuit board body 1 is transferred to the first heat sink 2, and the heat on the first heat sink 2 is transferred to the second heat sink 3. The first heat sink 2 and the second heat sink 3 help to dissipate the heat generated on the LED power circuit board body 1.

[0039] During use, the height of the LED power circuit board body 1 assembled into the LED power supply can be easily adjusted, which helps to assemble the LED power circuit board body 1 into the LED power supply at different heights, so as to adjust the height according to the required usage of the LED power circuit board body 1, which helps to ensure the heat dissipation efficiency of the LED power circuit board body 1 during use, and facilitates the use of the LED power circuit board body 1.
