[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please refer to Figures 1 to 7 Example 1:

[0028] This utility model proposes a transformer for LED driver power supply, including: a bottom assembly 1 and a top assembly 2; the bottom assembly 1 includes a mounting base 101, a control rod 102 and two locking blocks 103, the control rod 102 is rotatably connected inside the mounting base 101, and the two locking blocks 103 are symmetrically inserted into the inside of the mounting base 101; the top assembly 2 includes a protective cover 201 and a circuit board 202, the protective cover 201 is inserted into the top of the mounting base 101, and the circuit board 202 is inserted into the top of the mounting base 101, the electronic components required for transformer are installed on the circuit board 202, and the connecting wires on both sides of the circuit board 202 extend out of the inside of the protective cover 201.

[0029] The control rod 102 has threads on its outer surface and is screwed into the locking block 103 via these threads. In use, the control rod 102 controls the installation position of the protective cover 201 on the top of the mounting base 101. After inserting the protective cover 201 into the top of the mounting base 101, rotating the control rod 102 locks the protective cover 201 in place. Rotating the control rod 102 moves the locking block 103 via its threads. The top of the locking block 103 has a locking stop 1031, and the bottom side of the protective cover 201 has a locking groove 2014. The cross-sections of both the locking stop 1031 and the groove 2014 are right-angled triangles. The hypotenuse of the locking stop 1031 and the groove 2014 are also right-angled triangles. The inclined sides of the groove 4 are all set downwards. The locking block 1031 is inserted into the inside of the locking groove 2014. When the locking block 103 moves towards the protective cover 201, the locking block 1031 can be inserted into the inside of the locking groove 2014. Under the action of the resistance and compression between the locking block 1031 and the inclined side of the locking groove 2014, the locking block 103 can provide a downward locking force for the protective cover 201 when it moves, so that the protective cover 201 can be installed on the top of the mounting base 101 for use. When it is necessary to remove the protective cover 201, the two locking blocks 103 can be moved away from each other by the control rod 102. The operation is convenient and the installation and removal are quick. After the protective cover 201 is in contact with the installation state, its locking effect on the circuit will also disappear, and the circuit board 202 can be freely removed from the top of the mounting base 101.

[0030] The mounting base 101 has a positioning post 1011 on its top, and the circuit board 202 has a positioning groove 2021 inside. The positioning post 1011 is inserted into the positioning groove 2021. The protective cover 201 has an alignment post 2011 inside, and a locking block 2012 is inserted into the bottom of the alignment post 2011. When the protective cover 201 is installed on the top of the mounting base 101, the alignment post 2011, the locking block 2012, and the positioning post 1011 are on the same vertical line. The top of the locking block 2012 has a locking spring 2013, and the two ends of the locking spring 2013 abut against the top of the locking block 2012 and the inside of the protective cover 201, respectively. In use, the circuit board 202 can pass through the positioning post 1011. In conjunction with the positioning groove 2021, the circuit board 202 is positioned inside the mounting base 101. At the same time, the protective cover 201 can lock the circuit board 202, ensuring that the circuit board 202 is stably positioned inside the mounting base 101 and will not be displaced by external impacts or other forces, thus ensuring stable use. When the protective cover 201 is installed on the top of the mounting base 101, the locking block 2012 can abut against the top of the circuit board 202, and the locking block 2012 can compress the locking top spring 2013. Thus, the locking block 2012 transmits the pressure of the locking top spring 2013 to the circuit board 202, applying a locking force to the circuit board 202 and ensuring the stable use of the circuit board 202.

[0031] The working principle of this embodiment: The connecting wires on both sides of the circuit board 202 are connected to the power supply and the LED controller, respectively, to supply power to the LED. When it is necessary to inspect and maintain the circuit board 202 and its top electronic components, the installation state of the protective cover 201 on the top of the mounting base 101 can be controlled by the control lever 102. After inserting the protective cover 201 into the top of the mounting base 101, rotating the control lever 102 can lock the protective cover 201 in place on the top of the mounting base 101 for use. When rod 102 rotates, it can drive locking block 103 to move via the rod thread. When locking block 103 moves toward protective cover 201, locking abutment 1031 can be inserted into locking abutment groove 2014. Under the abutment and compression action between locking abutment 1031 and the inclined side of locking abutment groove 2014, locking block 103 can provide a downward locking force for protective cover 201 when moving, thereby installing protective cover 201 on top of mounting base 101 for use. When it is necessary to remove protective cover 201... At time 1, the two locking blocks 103 can be moved away from each other by the control lever 102, which is convenient to operate and quick to install and remove. Furthermore, after the protective cover 201 is in the installation state, its locking effect on the circuit disappears, and the circuit board 202 can be freely removed from the top of the mounting base 101. The circuit board 202 can be positioned inside the mounting base 101 by the cooperation of the positioning pin 1011 and the positioning groove 2021. Simultaneously, the protective cover 201 can lock the circuit board 202, ensuring the circuit... The circuit board 202 can be stably positioned inside the mounting base 101 and will not be displaced due to external impacts or other forces, ensuring stable use. When the protective cover 201 is installed on the top of the mounting base 101, the locking block 2012 can abut against the top of the circuit board 202, and the locking block 2012 can compress the locking top spring 2013. Thus, the locking block 2012 transmits the pressure of the locking top spring 2013 to the circuit board 202, applying a locking force to the circuit board 202 and ensuring the stable use of the circuit board 202.

[0032] In another embodiment, the protective cover 201 is provided with heat dissipation holes, which can improve the heat dissipation effect of the circuit board 202 and its top electronic components, and further improve the stability of the device.
