The lower fixing seat 6 is provided on the top of the slide 5. The lower fixing seat 6 and the upper fixing seat 7 are slidably connected. The first adjusting cylinder 8 is provided on the top of the lower fixing seat 6, and the upper fixing seat 7 is provided at the output end of the first adjusting cylinder 8.

[0020] When using the LED module aging test rack of this utility model, the slide 5 of the adjustable fixing bracket of the LED module is pulled out from the moving track at the bottom of the fixed cabinet 2, so that the LED module can be placed between the lower fixing seat 6 and the upper fixing seat 7. Then, the upper fixing seat 7 is lowered and fixed by controlling the first adjusting cylinder 8 to fix the LED module. Then, the movable cabinet 3 is moved to separate it from the fixed cabinet 2. Then, the position of the signal connector 4 on the lifting mechanism is adjusted to match the position of the pin header on the LED module. Then, the movable cabinet 3 is moved in the opposite direction to connect the signal connector 4 to the pin header on the LED module.

[0021] The fixed cabinet 2 has sliding holes at the four corners of its back, and the movable cabinet 3 has sliding rods 9 at the four corners of its front. The sliding rods 9 are slidably connected to the sliding holes. The bottom plate 1 of the movable cabinet 3 has a sliding groove 10, and the bottom of the movable cabinet 3 is slidably connected to the sliding groove 10. This design ensures high stability during movement of the movable cabinet 3 and facilitates precise connection between the signal connector 4 and the pin header on the LED module.

[0022] Both the lower fixed base 6 and the upper fixed base 7 are equipped with a second adjusting cylinder 11. A first movable pressure plate 12 is located on one side of the lower end of the lower fixed base 6, and a second movable pressure plate 13 is located on one side of the upper end of the upper fixed base 7. The first movable pressure plate 12 and the second movable pressure plate 13 are respectively connected to the output ends of the corresponding second adjusting cylinders 11. By using the second adjusting cylinders 11 to drive the first movable pressure plate 12 and the second movable pressure plate 13 to move, the combination of the first movable pressure plate 12 with the lower fixed base 6 and the combination of the second movable pressure plate 13 with the upper fixed base 7 can fix LED modules of different thicknesses, achieving high adaptability and high fixing stability.

One end of the drive rod 19 has a first bevel gear 17, and the lower end of the linear lead screw 15 has a second bevel gear 18. The second bevel gear 18 meshes with the first bevel gear 17. In this utility model, one end of the drive rod 19 extends through the side wall of the movable cabinet 3, making it convenient for the operator to operate the drive rod 19 from the side wall of the movable cabinet 3. When the drive rod 19 is rotated, the first bevel gear 17 drives the linear screw 15, which is equipped with the second bevel gear 18, to rotate. As a result, the mounting base 16 moves synchronously on the mounting groove 14 and the linear screw 15, thereby realizing the lifting and lowering adjustment.

[0024] Both the lower fixing base 6 and the upper fixing base 7 are provided with push-pull handles 20 on their front sides. The push-pull handles 20 facilitate the movement of the adjustable fixing frame for the LED module.

[0025] This invention features an adjustable LED module mounting bracket consisting of a slide block 5, a lower fixed seat 6, an upper fixed seat 7, and a first adjusting cylinder 8, which slides on a moving track inside the fixed cabinet 2. The clamping height between the lower fixed seat 6 and the upper fixed seat 7 is adjusted by raising and lowering the upper fixed seat 7 via the first adjusting cylinder 8, thus adapting to LED modules of different sizes for aging tests. The invention also features a signal connector 4 mounted on a lifting mechanism inside the movable cabinet 3. The position of the signal connector 4 can be adaptively adjusted according to the position of the pin header on the LED module fixed to the adjustable mounting bracket, resulting in high adaptability.
