[0002] The LED light tube, commonly known as the lamp tube (fluorescent lamp tube), uses an LED as the light-emitting body. The traditional fluorescent lamp tube, also known as a fluorescent lamp, has a filament at each end of the tube. The tube is filled with a small amount of argon and a thin mercury vapor. The inner wall of the tube is coated with a fluorescent powder. When the gas between the two filaments conducts electricity, ultraviolet rays are emitted, causing the fluorescent powder to emit visible light.

[0003] Common metal brackets for LED lamp tubes only include a support structure, which can support the LED lamp tube, but lack a light-shielding and adjusting structure. They cannot ensure that the irradiation angle and height of the LED lamp tube can be adjusted according to the actual use situation and change the light intensity. It is easy to occur that the irradiation angle and height of the LED lamp tube cannot match the actual use situation, affecting the adaptability of the LED lamp tube and the eyesight of personnel.

[0004] Therefore, aiming at the problem that the above-mentioned metal bracket for LED lamp tubes lacks a light-shielding and adjusting structure and cannot ensure that the irradiation angle and height of the LED lamp tube can be adjusted according to the actual use situation and change the light intensity, it is urgently needed to be solved to improve the use scenario of the metal bracket for LED lamp tubes. Content of the Utility Model

[0006] The technical solution of the utility model is: an adjustable metal bracket for LED lamp tubes, including a support bottom plate. A driving component is arranged on the top of the support bottom plate. The driving component is composed of a support rod, a sliding groove, a motor and a lead screw. Support rods are symmetrically welded on both sides of the top of the support bottom plate. An adjusting component is arranged in the middle of the two support rods. The adjusting component is composed of an adjusting rod, a U-shaped fixing frame, a connecting rod, a connecting block, a rotating groove, a first arc-shaped spring piece and a second arc-shaped spring piece. An adjusting rod is arranged in the middle of the two support rods. Connecting rods are symmetrically arranged at both ends of the adjusting rod. One end of the connecting rod is inserted into the inside of the sliding groove. A light-shielding component is arranged above the adjusting component. The light-shielding component is composed of a fixing block, a mounting block, a mounting groove and an L-shaped light-shielding plate. Fixing blocks are symmetrically arranged above the adjusting rod corresponding to the positions of the two connecting rods.

This is to solve the problem that common LED lamp tubes with metal brackets only contain a supporting structure, which can support the LED lamp tube, but lack a light-shielding and adjusting structure, and cannot ensure that the irradiation angle and height of the LED lamp tube can be adjusted according to the actual use situation and change the light intensity. It is easy to occur that the irradiation angle and height of the LED lamp tube cannot be adapted to the actual use situation, affecting the adaptability of the LED lamp tube and the eyesight of personnel.

[0008] Preferably, a sliding groove is formed on the side surface of the support rod, and a motor is fixed by bolts at the position corresponding to the sliding groove at the top of the support rod. When it is necessary to adjust the height of the LED lamp, the motor is started, and the motor drives the lead screw to rotate.

[0009] Preferably, a lead screw is arranged inside the sliding groove, and the top end of the lead screw passes through the connecting rod, the fixing block and the support rod and is connected to the output end of the motor. The rotating lead screw drives the LED lamp to move up and down through the connecting rod.

[0010] Preferably, a connecting block is welded to the top of the connecting rod, and the top end of the connecting block is welded to the bottom of the fixing block. Through the connection of the connecting block, the fixing block and the connecting rod move together, and the fixing block drives the L-shaped light-shielding plate and the LED lamp to move together.

[0011] Preferably, two U-shaped fixing frames are symmetrically fixed to the side surface of the adjusting rod by bolts. Rotating grooves are symmetrically formed at both ends of the adjusting rod, and first arc-shaped spring pieces are welded at equal intervals on the inner wall of the rotating groove. The LED lamp tube is clamped into the inside of the U-shaped fixing frame, and then the LED lamp tube is fixed to the inside of the U-shaped fixing frame by bolts.

The connecting rod is connected to the adjusting rod by inserting the second arc-shaped spring pieces into the inside of the rotating groove, and the second arc-shaped spring pieces are engaged with the first arc-shaped spring pieces. When it is necessary to change the irradiation angle of the LED lamp, the adjusting rod is rotated, and the adjusting rod drives the LED lamp tube to rotate. At this time, the first arc-shaped spring pieces and the second arc-shaped spring pieces will be pressed against each other. When the rotation of the adjusting rod stops, the first arc-shaped spring pieces and the second arc-shaped spring pieces are engaged with each other, realizing the functions of adjusting the irradiation angle and height of the LED lamp tube, and preventing the problem that the irradiation angle and height of the LED lamp tube cannot be adapted to the actual use situation, affecting the adaptability of the LED lamp tube.
