Description

Technical Field

[0001] This utility model relates to the field of LED desk lamp technology, specifically a high-stability LED desk lamp. Background Technology

[0002] An LED desk lamp is a desk lamp that uses LEDs (Light Emitting Diodes) as its light source. An LED is a solid-state semiconductor device that can directly convert electricity into light. The LED lighting technology it uses is a third-generation lighting technology. While the blue light emitted by LED desk lamps can be harmful to the eyes, they also have a number of advantages.

[0003] Existing desk lamps generally lack a stabilizing device during installation. As a result, the lamp's center may become unstable when the support arm is adjusted, leading to instability and potential tipping over, causing inconvenience. Therefore, we propose a novel, highly stable LED desk lamp. Utility Model Content

[0038] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0039] This utility model provides a technical solution:

[0040] Please see Figures 1-3 A high-stability LED desk lamp includes a base 1 and a cavity 8 formed therein, wherein an adsorption mechanism is provided in the cavity 8.

[0041] The adsorption mechanism includes multiple threaded tubes 12 that are rotatably connected to the lower end of the chamber 8 and the base 1. Each of the multiple threaded tubes 12 is threaded with a threaded rod 14. Each of the multiple threaded rods 14 has a suction cup 6 at its lower end. As the threaded rods 14 move continuously, they squeeze the suction cups 6, causing the suction cups 6 to adhere tightly to the table, increasing the adsorption force between the base 1 and the table, and ensuring the stability of the desk lamp when placed.

[0042] Furthermore, the upper end of the base 1 is provided with a support arm 3, which is L-shaped. The top of the support arm 3 is provided with a lamp tube 4, and the lower end of the base 1 is provided with multiple symmetrically arranged support feet 2.

[0043] Furthermore, each of the upper ends of the multiple threaded rods 14 is provided with a limiting frame 7, which is U-shaped. The multiple limiting frames 7 pass through the cavity 8 and the lower end of the base 1 and are slidably connected to it.

[0044] Furthermore, the chamber 8 is rotatably connected to the front end of the base 1 by two symmetrically arranged transmission rods 9, one of which has a knob 5 at its end.

[0045] Furthermore, both transmission rods 9 are provided with synchronous pulleys 10 on their outer walls, and the two synchronous pulleys 10 are connected by a synchronous belt drive.

[0046] Furthermore, both ends of the two transmission rods 9 are provided with worm gears 15 on their outer walls, and the outer walls of the multiple internally threaded tubes 12 are provided with worm wheels 13 that cooperate with the worm gears 15. By setting up multiple pairs of worm gears 15 and worm wheels 13 to cooperate with each other and the synchronous transmission of the two synchronous pulleys 10, the multiple threaded rods 14 are ensured to move synchronously, thereby improving the overall linkage of the device.

[0047] Furthermore, damping pads 11 are provided at the rotational connection points of the two transmission rods 9 and the chamber 8, and the number of damping pads 11 is four.

[0048] In practical use, the working principle of this utility model is as follows:

[0049] When placing the desk lamp, place the base 1 on a horizontal table and turn the knob to drive one of the transmission rods 9 to rotate. The synchronous pulley 10 and synchronous belt between the two transmission rods 9 cause them to rotate synchronously (the damping pad 11 limits the position of the transmission rod 9 after rotation, without affecting its normal rotation). This causes multiple worm gears 13 to rotate. The worm gears 15 and worm wheels 13 then rotate, driving multiple internally threaded tubes 12 to rotate. The threaded connection between the internally threaded tubes 12 and the threaded rods 14, along with the limiting effect of the limiting frame 7, causes the multiple threaded rods 14 to move within the internally threaded tubes 12. This movement pushes the suction cups 6 downwards, bringing them into contact with the table. As the threaded rods 14 continue to move, they compress the suction cups 6, causing them to adhere tightly to the table, increasing the adhesion between the base 1 and the table and ensuring the stability of the desk lamp during placement.

[0050] In summary, a high-stability LED desk lamp, by improving and optimizing its working principle, eliminates the problem of the lamp tipping over when placed in the existing technology, which lacks a device to stabilize the lamp.

[0051] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
