They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Given the current technology, existing lighting devices generally have fixed lamp tubes, which cannot adjust the lighting range during actual use, resulting in poor practicality.

[0026] As shown in the accompanying drawings, this embodiment of the invention provides an easily adjustable lighting device.

[0027] The device includes: a top plate 12 on the top of a support rod 11; an adjustment assembly 2 on the top plate 12, the adjustment assembly 2 including: a rotating block 21 rotatably disposed on the outer side wall of the top plate 12; a lamp plate 22 fixedly disposed on one end of the rotating block 21; one end of a connecting rod 23 rotatably connected to one end of the rotating block 21; a moving block 24 disposed above the top plate 12 and rotatably connected to the outer side wall of the connecting rod 23; and a threaded rod 25 whose bottom end passes through the moving block 24 and is rotatably connected to the top plate 12 and threadedly connected to the moving block 24.

[0028] Specifically, the support rod 11 has wires inside and is connected to a plug (the plug is a commonly used electrical connection component and is not shown in the attached drawing). The wires are connected to the lamp panel 22 to supply power and provide lighting to the lamp panel 22 (the wires are a basic component of the lighting device and are not shown in the attached drawing).

[0029] In use, simply grasp the threaded rod 25 and control its rotation. During rotation, it connects threadedly to the moving block 24. Because the outer side of the moving block 24 is connected to the connecting rod 23 and its rotation is restricted, the moving block 24 can be moved up and down while the threaded rod 25 rotates. During this movement, the moving block 24 drives the connecting rod 23 to rotate, dragging the rotating block 21 to adjust the angle of the lamp panel 22. Controlling the unfolding of the lamp panel 22 adjusts the lighting range. Suitable for study desks or bedside tables, the unfolding of the lamp panel 22 adjusts the lighting range, thus regulating the room's brightness. Convenient for getting up or doing homework.

[0030] In some embodiments, the rotating block 21, the lamp plate 22, and the connecting rod 23 are provided in eight sets.

[0031] It has eight groups that can improve the lighting effect and make it better.

[0032] In some embodiments, the adjustment assembly 2 further includes a knob 26 fixedly disposed on the top of the threaded rod 25.

[0033] The knob 26 is designed for easy gripping and control of the rotation of the threaded rod 25. At the same time, the grooves on the surface of the knob 26 can increase friction when rotating.

[0034] In some embodiments, the adjustment assembly 2 further includes a rubber pad 27 fixedly disposed at the bottom of the support rod 11.

[0035] The design of the rubber pad 27 increases friction, making the support rod 11 more stable when placed on the table.

[0036] In some embodiments, a lifting assembly 3 is provided on the support rod 11. The lifting assembly 3 further includes: an inner rod 31 disposed inside the support rod 11 and fixedly connected to the top plate 12 at its top end; a positioning hole 32 opened on the outer side wall of the inner rod 31; and a pin 33 with one end penetrating through the support rod 11 and inserted into the positioning hole 32.

[0037] When the height of the top plate 12 needs to be adjusted, the pin 33 can be pulled out to disengage it from the positioning hole 32, thus releasing the restriction on the inner rod 31. Then, the inner rod 31 can be moved upwards to adjust the height of the top plate 12. After adjusting to the appropriate position, the pin 33 can be inserted through the support rod 11 into the positioning hole 32 to complete the restriction on the inner rod 31. Adjust the height of the top plate 12.

[0038] In some embodiments, the lifting assembly 3 further includes a spring 34 sleeved on the outside of the pin 33, and its two ends are fixedly connected to the support rod 11 and the pin 33 respectively.

[0039] The spring 34 is designed to pull the pin 33 with its own elasticity, so that the pin 33 is stably inserted into the positioning hole 32 and is not easy to fall out.

[0040] In some embodiments, the lifting assembly 3 further includes a cone 35 fixedly disposed at one end of the pin 33.

[0041] The pointed end of the cone 35 makes it relatively easier to insert into the positioning hole 32.

[0042] In some embodiments, the lifting assembly 3 further includes: a through groove 36 formed on the outer side wall of the support rod 11; one end of a slider 37 is inserted into the interior of the through groove 36 and is fixedly connected to the inner rod 31.

[0043] When the inner rod 31 moves, it causes the slider 37 to slide inside the through groove 36, which can limit the rotation of the inner rod 31, so that the positioning hole 32 on the inner rod 31 is better aligned with the pin 33, and at the same time, it can also prevent the inner rod 31 from disengaging from the support rod 11.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
