For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

As shown in FIGS. 1-3, a downlight fixing device of the present embodiment includes a fixing tube 10 and a lamp tube 20. A spring 11 is fixedly installed inside the fixing tube 10. A movable ring 12 is fixedly installed at the bottom end of the spring 11. The lamp tube 20 fits the movable ring 12. The movable ring 12 squeezes the spring 11. The bottom of the movable ring 12 abuts against the top of the lamp tube 20. A limiting slide bar 13 is arranged inside the fixing tube 10. The lamp tube 20 moves downward under the elastic force of the spring 11, so that the limiting slide bar 13 is stuck in the limiting groove 23. The lamp tube 20 A connecting frame 21 is fixedly installed on the surface of the connecting frame 21, and an insertion groove 22 and a limiting groove 23 are opened on the surface of the connecting frame 21. After the lamp tube 20 is deeply inserted into the fixed tube 10, the insertion groove 22 is separated from the limiting slide 13, the lamp tube 20 is rotated, and then the hand is released. The elastic force of the spring 11 makes the limiting slide 13 stuck in the inside of the limiting groove 23, and the limiting slide 13 is slidably connected with the inside of the insertion groove 22. The insertion groove 22 is aligned with the limiting slide 13, and then the lamp tube 20 is inserted into the fixed tube 10, and the top of the limiting slide 13 is engaged with the limiting groove 23.

Embodiment 1: A mounting ring 14 is fixedly connected to the surface of the fixing tube 10, and a mounting sleeve 15 is threadedly connected to the surface of the fixing tube 10. When the fixing tube 10 is inserted into the ceiling, the mounting sleeve 15 is rotated so that the mounting sleeve 15 and the mounting ring 14 clamp and fix the ceiling.

Embodiment 2: A beautifying sheet 24 is fixedly installed at the bottom of the lamp tube 20 . When the lamp tube 20 is inserted into the fixing tube 10 , the beautifying sheet 24 covers the entrance of the fixing tube 10 .

Embodiment 3: A wire rack 30 is fixedly installed on the top of the lamp tube 20, and a return spring 31 is fixedly installed inside the wire rack 30. A tightening sleeve 32 is fixedly installed on one end of the return spring 31. The movement of the tightening sleeve 32 drives the return spring 31 to deform. A tightening groove 33 is provided at one end of the tightening sleeve 32. A tightening nut 34 is threadedly connected to the surface of the tightening sleeve 32. The interior of the tightening sleeve 32 clamps the wire 35. One end of the wire 35 is fixedly installed on the lamp tube 20. When the lamp tube 20 needs to be installed, the wire 35 is pulled, and the wire 35 drives the tightening sleeve 32 to move. After the wire 35 is connected to the lamp tube 20, the reset spring 31 pulls the wire 35 back to its place when the lamp tube 20 is installed with the fixing tube 10, so as to prevent the wire from accidentally shrinking into the ceiling.

The working principle of the utility model is as follows: when in use,

1. The device aligns the insertion groove 22 with the limiting slide 13, and then inserts the lamp tube 20 into the fixed tube 10, so that the lamp tube 20 fits the movable ring 12, and the movable ring 12 squeezes the spring 11. After the lamp tube 20 goes deep into the fixed tube 10, the insertion groove 22 and the limiting slide 13 are separated, the lamp tube 20 is rotated, and then the hand is released, so that the lamp tube 20 moves downward under the elastic force of the spring 11, and the limiting slide 13 is stuck in the inside of the limiting groove 23, so that when the main body of the lamp tube 10 is replaced, it only needs to be inserted, twisted, and then released to complete the fixation.

2. When the lamp tube 20 needs to be installed, pull the wire 35, and the wire 35 drives the tightening sleeve 32 to move. The movement of the tightening sleeve 32 drives the reset spring 31 to deform, thereby pulling out the wire 35. After the wire 35 is connected to the lamp tube 20, the reset spring 31 pulls the wire 35 back to its original position when the lamp tube 20 is installed with the fixing tube 10, so as to prevent the wire from accidentally shrinking into the ceiling.

Compared with the prior art, the present invention has the following beneficial effects:

1. The device aligns the insertion groove 22 with the limiting slide 13, and then inserts the lamp tube 20 into the fixed tube 10, so that the lamp tube 20 fits the movable ring 12, and the movable ring 12 squeezes the spring 11. After the lamp tube 20 goes deep into the fixed tube 10, the insertion groove 22 and the limiting slide 13 are separated, the lamp tube 20 is rotated, and then the hand is released, so that the lamp tube 20 moves downward under the elastic force of the spring 11, so that the limiting slide 13 is stuck in the inside of the limiting groove 23, so that when the main body of the lamp tube 10 is replaced, it only needs to be inserted and twisted and then released to fix it, and the operation is relatively simple.

2. When the lamp tube 20 needs to be installed, the wire 35 is pulled, and the wire 35 drives the tightening sleeve 32 to move. The movement of the tightening sleeve 32 drives the reset spring 31 to deform, thereby pulling out the wire 35. After the wire 35 is connected to the lamp tube 20, the reset spring 31 pulls the wire 35 back into place when the lamp tube 20 is installed with the fixing tube 10, so as to prevent the wire 35 from blocking the fixing tube 10 and preventing the wire from accidentally shrinking into the ceiling, and the connection is more convenient.
