Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to an easily adjustable table lamp. Background Technology

[0002] The primary function of a desk lamp is illumination, making it particularly suitable for activities requiring concentration, such as reading, writing, and drawing. A desk lamp provides focused and direct light, allowing for clear reading of text, reducing eye strain, and improving visual acuity. Furthermore, the color temperature and brightness of a desk lamp can be adjusted as needed, effectively preventing eye fatigue and nearsightedness.

[0003] Existing desk lamps are fixed in place after height adjustment by inserting a positioning pin into a positioning hole or by pressing one end of a screw against the support rod. However, the inventor believes that these methods, which involve installing mating parts on the surface of the lamp casing, negatively impact the lamp's aesthetic appearance. To address this issue, a desk lamp that is easy to adjust is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an easily adjustable table lamp.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable desk lamp includes a base. A control board is installed on the inner bottom wall of the base. An anti-detachment sleeve is fixedly connected to the inner wall of the base. A conductive plate is installed on the inner wall of the anti-detachment sleeve. The control board and the conductive plate are fixedly connected to the same power supply line. A lifting rod is sleeved inside the anti-detachment sleeve. An adjustment shaft is rotatably connected to the inner wall of the top of the lifting rod. A lighting lamp is fixedly connected to the surface of the adjustment shaft. A power connector is installed inside the anti-detachment sleeve. The inner wall of the anti-detachment sleeve has a clearance vertical groove and multiple L-shaped grooves. The conductive plate is installed inside the L-shaped grooves. One end of the power connector is in contact with the surface of the conductive plate. An adjustment and positioning mechanism is installed on the surface of the lifting rod.

[0007] Preferably, the adjustment and positioning mechanism includes a connecting block fixedly connected to the surface of the lifting rod, a sliding rod slidably connected to the inner wall of the connecting block, and a ball head fixedly connected to one end of the sliding rod.

[0008] Preferably, a spring telescopic rod is fixedly connected to the surface of the connecting block, one end of the spring telescopic rod is fixedly connected to the surface of the slide rod, and a limit ring is fixedly connected to the surface of the adjusting shaft.

[0009] Preferably, the surface of the limiting ring is provided with multiple ball grooves, the ball head is adapted to the ball grooves, and a knob is fixedly connected to the surface of the limiting ring.

[0010] Preferably, an anti-slip sleeve is fixedly connected to the surface of the lifting rod, and a marking label is provided on the surface of the anti-slip sleeve. A sealing ring is fixedly connected to the inner wall of the anti-detachment sleeve, and the surface of the sealing ring is in pressure contact with the surface of the lifting rod.

[0011] Preferably, the inner wall of the ball groove is provided with rounded corners, and the surface of the lifting rod is provided with scale lines.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The power connector contacts the conductive plate at the corresponding height, energizing the lamp. The L-shaped groove ensures the stability of the power connector within the groove, preventing rotation after the lifting rod is adjusted. This height adjustment method allows for concealed height adjustment, maintaining the lamp's aesthetic appearance.

[0014] 2. When adjusting the angle of the lighting lamp, if the torque is greater than the resistance of the ball head in the ball groove, a smooth transition is achieved by rounding the corners. The compressed spring telescopic rod shortens, and when the ball head is re-engaged in the ball groove under the action of the spring telescopic rod, the angle of the adjustment shaft after rotation is positioned.

[0022] Power supply line 10 connects to the conductive plate 5 for power supply. Lifting rod 3 adjusts the height of the lamp 4. Adjustment shaft 20 supports the rotation of the lamp 4. Power connector 9 transmits electricity. Vertical groove 18 and multiple L-shaped grooves 19 provide space for the power connector 9 to move and avoid obstacles. Power supply is supplied when the power connector 9 contacts the conductive plate 5 at different heights. Adjustment and positioning mechanism allows the lamp 4 to be adjusted in a concealed manner, ensuring the aesthetic appearance of the lamp.

[0023] In this utility model, the adjustment and positioning mechanism includes a connecting block 12 fixedly connected to the surface of the lifting rod 3, a sliding rod 14 slidably connected to the inner wall of the connecting block 12, and a ball head 15 fixedly connected to one end of the sliding rod 14.

[0024] By setting the connecting block 12, the sliding stability of the slide rod 14 is maintained, and by setting the ball head 15, it cooperates with the ball groove 16 to limit the limit ring 17.

[0025] In this utility model, a spring telescopic rod 13 is fixedly connected to the surface of the connecting block 12, one end of the spring telescopic rod 13 is fixedly connected to the surface of the slide rod 14, and a limit ring 17 is fixedly connected to the surface of the adjusting shaft 20.

[0026] By setting the spring telescopic rod 13, the slide rod 14 is driven to slide back to its original position.

[0027] In this utility model, the surface of the limiting ring 17 is provided with a plurality of ball grooves 16, the ball head 15 is adapted to the ball grooves 16, and a knob 11 is fixedly connected to the surface of the limiting ring 17.

[0028] By setting the ball head 15 to match the ball groove 16, the limit ring 17 is prevented from rotating under the resistance of the ball head 15. By setting the knob 11, the limit ring 17 is driven to rotate under force.

[0029] In this utility model, an anti-slip sleeve 21 is fixedly connected to the surface of the lifting rod 3, and a marking label 6 is provided on the surface of the anti-slip sleeve 21. A sealing ring 7 is fixedly connected to the inner wall of the anti-detachment sleeve 2, and the surface of the sealing ring 7 is in contact with the surface of the lifting rod 3.

[0030] By setting a marker label 6, the angle position of the power supply connector 9 can be determined, and by setting a sealing ring 7, waterproof sealing can be achieved.

[0031] In this invention, the inner wall of the ball groove 16 is provided with a rounded corner 23, and the surface of the lifting rod 3 is provided with scale lines 22.

[0032] By setting the rounded corner 23, when the torque is greater than the resistance after the ball head 15 is subjected to force, a smooth transition is achieved. By setting the scale line 22, the height of the lifting rod 3 can be adjusted.

[0033] Working principle: When the height of the lifting rod 3 needs to be adjusted, the operator, with the assistance of the scale line 22 and the label 6, pushes the power connector 9, which was originally located in one of the L-shaped slots 19, out of the L-shaped slot 19. After adjusting it to a suitable position within the space of the vertical slot 18, the power connector 9 is pushed back into the corresponding L-shaped slot 19, so that one end of the power connector 9 is in contact with the surface of the conductive plate 5. At this time, the bulb in the lighting lamp 4 is powered on and lit. When the rotation angle between the lighting lamp 4 and the adjusting shaft 20 needs to be adjusted, the operator turns the knob 11 to force the limiting ring 17. When the torque is greater than the resistance of the ball head 15 in the ball groove 16, a smooth transition is achieved through the rounded corner 23. At this time, the compression spring telescopic rod 13 shortens. When the ball head 15 is re-engaged in the ball groove 16 under the action of the spring telescopic rod 13, the angle of the adjusted shaft 20 after rotation is positioned. With the above structure, the height of the lighting lamp 4 can be adjusted in a hidden way when adjusting the height, ensuring the aesthetics of the lamp's exterior.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
