Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to a fixed ceiling-mounted LED lamp. Background Art

[0002] With the rapid development of lighting technology, LED lamps, with their high efficiency, long lifespan, and environmental friendliness, have gradually replaced traditional lighting equipment and become the mainstream choice for indoor lighting. In particular, LED ceiling lamps are highly favored in commercial spaces, homes, and public facilities for their space-saving, environmentally friendly, and optimized light distribution.

[0003] Traditional LED ceiling lights are usually installed by fixing them directly to the ceiling with screws. Although this method is simple and direct, in actual application, due to loose screws or differences in ceiling materials, the lamp may be unstable and prone to shaking or falling off after long-term use, which not only affects the lighting effect but also poses a safety hazard. Utility Model Content

[0004] The purpose of the present invention is to provide a fixed ceiling-mounted LED lamp to solve the problem proposed in the above background technology that traditional LED ceiling lamps are usually installed by directly fixing them to the ceiling with screws. Although this method is simple and direct, in actual application, due to loose screws or differences in ceiling materials, the lamp may be unstable and prone to shaking or falling off after long-term use, which not only affects the lighting effect but also poses a safety hazard.

[0005] The top of the fixing plate is fixedly mounted on the top of the fixing plate, and the bottom of the fixing plate is fixedly mounted on the top of the fixing plate, and the fixing plate is fixedly mounted on the top of the fixing plate.

[0006] Compared with the prior art, the beneficial effects of the present invention are:

[0007] This fixed ceiling-mounted LED lamp forms a primary fixing mechanism through the close contact between the anti-friction plate fixed at the bottom of the extension plate and the top surface of the ceiling. The anti-friction plate not only increases the contact area but also reduces friction loss through its material properties, effectively preventing the lamp from loosening during long-term use. The suction block fixed at the top of the lifting rod contacts the bottom of the ceiling, forming a secondary fixing mechanism, further enhancing the adhesion between the lamp and the ceiling, ensuring the lamp remains stable in various environments. A bidirectional micro-cylinder installed in the movable groove, through its output end fixedly connected to the inner plate, enables flexible horizontal adjustment of the extension plate and anti-friction plate. This design allows the LED lamp to be fine-tuned according to the actual conditions of the ceiling during installation, ensuring a perfect fit between the anti-friction plate and the ceiling, improving the accuracy and stability of installation. By turning the knob, the rotating rod can be driven to rotate through the cooperation of the external thread and the internal thread groove, thereby driving the lifting rod and suction block to rise and fall in the vertical direction. This design not only facilitates the adjustment of the lamp height during installation, but also allows for fine-tuning as needed during long-term use, ensuring that the lamp always maintains the optimal lighting position.

[0015] A limiting slot 11 is provided at the center of the top of the extension plate 9, and limiting blocks 12 are fixedly connected to both sides of the top of the movable slot 6. The bottom of the limiting block 12 passes through the interior of the limiting slot 11 and is slidably connected to the limiting slot 11.

[0016] A bidirectional micro cylinder 8 is fixedly installed on the top of the movable groove 6 , and the output ends on both sides of the bidirectional micro cylinder 8 are fixedly connected to the opposite sides of the two inner plates 7 respectively.

[0017] A support rod 13 is fixedly connected to the bottom of the movable groove 6 , and the support rod 13 is sleeved and slidably connected to the bottom of the two inner plates 7 .

[0018] A rotating rod 18 is rotatably connected to the bottom of the groove 15. An external thread 19 is provided on the top of the surface of the rotating rod 18. An internal thread groove 20 is provided at the center of the bottom of the lifting rod 16. The top of the rotating rod 18 passes through the interior of the internal thread groove 20 and is threadedly connected to the internal thread groove 20 through the external thread 19.

[0019] The bottom of the rotating rod 18 passes through the fixing column 14 and the connecting plate 2 in sequence and extends to the outside of the connecting plate 2 . The bottom end of the rotating rod 18 is fixedly connected to a knob 23 .

[0020] Movable grooves 21 are provided on both sides of the corresponding groove 15 inside the fixed column 14, and movable blocks 22 are fixedly connected to the bottom positions on both sides of the lifting rod 16. The side of the movable block 22 away from the lifting rod 16 passes through the interior of the movable groove 21 and is slidably connected to the movable groove 21.

[0021] Working principle: When the LED lamp needs to be installed, the mounting seat 3 passes through the inside of the mounting groove 5 opened in the top plate 4, and then the two-way micro cylinder 8 is started, and the output ends on both sides thereof push the two inner plates 7 to move back to each other. The movement of the inner plate 7 drives the extension plate 9 to expand outward along the sliding connection of the limiting slide groove 11 and the limiting block 12 until the anti-friction plate 10 is in close contact with the top surface of the top plate 4. After the extension plate 9 and the anti-friction plate 10 are expanded and contact the top plate 4, the position of the adsorption block 17 needs to be adjusted to contact with the bottom of the top plate 4. By rotating the knob 23, the rotating rod 18 is driven to rotate. Since the top surface of the rotating rod 18 has an external thread 1 9, and an internal thread groove 20 is opened at the center of the bottom of the lifting rod 16, so the rotation of the rotating rod 18 will drive the lifting rod 16 to move up and down in the groove 15, and the movement of the lifting rod 16 drives the adsorption block 17 to rise or fall until the adsorption block 17 is in close contact with the bottom of the top plate 4, forming a second-layer fixing mechanism. At the same time, the moving blocks 22 on both sides of the lifting rod 16 slide in the moving groove 21 to ensure the stability of the lifting rod 16 during the lifting process. When the anti-friction plate 10 of the extension plate 9 contacts the top of the top plate 4 and the adsorption block 17 contacts the bottom of the top plate 4, the LED lamp is firmly installed on the ceiling through the double fixing mechanism.

[0022] In summary: the fixed ceiling-mounted LED lamp forms a first-layer fixing mechanism through the close contact between the anti-friction plate 10 fixed at the bottom of the extension plate 9 and the top surface of the top plate 4. The anti-friction plate 10 not only increases the contact area, but also reduces friction loss through its material properties, effectively preventing the lamp from loosening during long-term use. The adsorption block 17 fixed on the top of the lifting rod 16 contacts the bottom of the top plate 4 to form a second-layer fixing mechanism, further enhancing the adhesion between the lamp and the top plate 4, ensuring that the lamp can remain stable in various environments. The two-way micro cylinder 8 set in the movable groove 6 is fixedly connected to the inner plate 7 through its output end , realizing flexible adjustment of the extension plate 9 and the anti-friction plate 10 in the horizontal direction. This design enables the LED lamp to be fine-tuned according to the actual situation of the ceiling during installation, ensuring that the anti-friction plate 10 is fully fitted with the top plate 4, improving the accuracy and stability of the installation. By turning the knob 23, the rotating rod 18 can be driven to rotate in cooperation with the external thread 19 and the internal thread groove 20, thereby driving the lifting rod 16 and the adsorption block 17 to rise and fall in the vertical direction. This design is not only convenient for adjusting the height of the lamp during installation, but also can be fine-tuned as needed during long-term use to ensure that the lamp always remains in the optimal lighting position.
