For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0033] In the first embodiment of the present utility model, an LED magnetic lamp power supply is provided. Refer to Figures 1 - 5 , which includes a power supply main body 1. The power supply main body 1 is magnetically connected to a guide rail 2. A clamping and mating portion 211 is provided on the guide rail 2. The power supply main body 1 includes:

[0034] A housing 11, inside which a connection cavity 114 is provided. An opening 13 and a through hole 14 communicating with the connection cavity 114 are provided on the outer side wall of the housing 11; and

[0035] A locking member 3, which is movably connected to the connection cavity 114 and includes a connection column 31. One end of the connection column 31 is elastically connected to the housing 11 through a spring 32. The spring 32 can be set as a straight spring 32. The other end of the connection column 31 passes through the opening 13 to form a pressing portion 33. Applying an external force to the pressing portion 33 can make the connection column 31 slide and compress the spring 32 to accumulate elastic potential energy.

[0036] Furthermore, an elastic member 34 is provided on the connection column 31. One end of the elastic member 34 is connected to the connection column 31, and the other end is provided with a clamping portion 341. The clamping portion 341 can elastically approach or move away from the connection column 31. The elastic member 34 can be made of a plastic material, so that the rigidity of the elastic member 34 is reduced and the deformation performance is increased, facilitating the elastic movement of the clamping portion 341 and making it not easily break.

The outer side wall of the clamping portion 341 facing the spring 32 is set as a sliding surface 342. Applying a force to the pressing portion 33 can compress the spring 32 and make the clamping portion 341 slide through the through hole 14 to release the clamping with the clamping and mating portion 211.

[0038] When in use, press the pressing part 33 to compress the spring 32. At this time, the spring 32 accumulates elastic potential energy. Meanwhile, the clamping part 341 slides through the through hole 14 to elastically approach the connecting column 31, so that the clamping between the clamping part 341 and the clamping cooperation part 211 is released, and the power supply main body 1 can be separated from the guide rail 2, facilitating the removal of the power supply main body 1 from the guide rail 2. When the pressing of the pressing part 33 is released, the spring 32 releases the elastic potential energy, and the clamping part 341 slides through the through hole 14 to elastically move away from the connecting column 31, so that it can be clamped with the clamping cooperation part 211, making the connection between the power supply main body 1 and the guide rail 2 convenient. Through the clamping between the clamping part 341 and the clamping cooperation part 211, the power supply main body 1 is not easily detached and the connection is stable. Through the mutual cooperation of the above structures of the present utility model, the disassembly operation between the power supply main body 1 and the guide rail 2 is more convenient, which is beneficial to the maintenance or replacement of the power supply main body 1.
