Description

Technical Field

[0001] The utility model relates to the field of table lamps, in particular to a table lamp which is easy to adjust. Background Art

[0002] As a household appliance, desk lamps have a wide range of applications, including but not limited to homes, offices, and study spaces, providing localized lighting. They not only meet basic lighting needs but also continue to evolve in areas such as eye protection, energy conservation, and intelligent features, offering users a more comfortable and convenient experience. With technological advancements, the technical scope of desk lamps is also expanding. Modern desk lamps not only utilize advanced lighting technologies such as LED light sources and intelligent dimming, but also incorporate cutting-edge technologies such as the Internet of Things and artificial intelligence, enabling more intelligent and personalized lighting services.

[0003] Existing desk lamps typically consist of a lampshade, bulb (or LED light source), bracket, switch, base, and power cord. The bulb provides illumination, the switch controls the on / off status, and the bracket supports the lampshade and bulb, protecting the bulb and controlling the direction of illumination. The base secures the lamp, while the power cord connects to the power source. Users control the on / off status of the desk lamp by adjusting the switch. The design of the lampshade, bracket, and other components, to a certain extent, determines the lighting effect and user comfort of the desk lamp.

[0004] However, although the existing desk lamps have made significant progress in terms of functional use, there are still some shortcomings. During use, due to the different body shapes and sitting postures of users, in order to better protect the eyes during use, it is often necessary to adjust the lighting angle of the desk lamp. Most desk lamps in the existing technology can only perform simple adjustments to the lighting direction, generally by adjusting the deformable folding lamp arm and the hinge adjustment of the connecting bracket. The adjustment angle still has certain limitations and inconveniences, which makes it difficult for users to conveniently adjust and control according to the lighting angle requirements, thereby affecting the use of the desk lamp.

DETAILED DESCRIPTION

[0025] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0026] In this embodiment, refer to Figure 1-Figure 5 The adjustable desk lamp specifically implemented includes a base 1 and a lighting lamp 2. The lighting lamp 2 is installed on the base 1 through a support rod 3. A connecting end 4 is formed on the base 1. One end of the support rod 3 is matched with the connecting end 4 through a rotating connecting shaft 5, and the other end of the support rod 3 is plugged with a retractable telescopic rod 6. The end of the telescopic rod 6 away from the support rod 3 is connected to a limited connecting seat 7. The limited connecting seat 7 is plugged with the end of the telescopic rod 6 through a plug-in portion 8, and the limited connecting seat 7 can rotate along the circumferential direction of the telescopic rod 6. A rotatable rotary joint 9 is connected to the limited connecting seat 7. The lighting lamp 2 is matched with the rotary joint 9 through a damping connecting sleeve 10, so that the rotary joint 9 can drive the lighting lamp 2 to rotate, and a damping connecting piece is connected between the lighting lamp 2 and the rotary joint 9.

[0027] The connecting end 4 is provided with a mounting hole for mating with the rotating connecting shaft 5. The rotating connecting shaft 5 is inserted into the mounting hole, and one end of the rotating connecting shaft 5 passes through the mounting hole and is connected to a rotation limit block 11. The rotating connecting shaft 5 is configured to rotate along the mounting hole, so that the rotating connecting shaft 5 can drive the support rod 3 to rotate to a desired angle, thereby improving the applicability and convenience of use.

[0028] The position-limiting connector 7 is formed with a plug-in portion 8 for connection to the end of the telescopic rod 6. A locking member 12 for locking is connected to the outer side of the plug-in portion 8. A rotating connection portion 13 for mounting the rotary joint 9 is formed on the position-limiting connector 7. The position-limiting connector 7 is arranged in a "T" shape. The position-limiting connector 7 is installed by plugging the plug-in portion 8 with the end of the telescopic rod 6, allowing it to rotate along the telescopic rod 6. The locking member 12 is provided through the plug-in portion 8 and locked with the outer side of the telescopic rod 6, thereby locking the rotation of the position-limiting connector 7.

[0029] One end of the rotary joint 9 is hingedly connected to the rotating connecting portion 13 . A threading hole 14 is provided inside the rotary joint 9 . The telescopic rod 6 and the support rod 3 are both hollow tubes.

[0030] The damping connection includes an oil-collecting washer 15 and a damping washer 16. One end of the damping connection sleeve 10 passes through the oil-collecting washer 15 and the damping washer 16 in sequence and is clamped and mounted to the rotary joint 9 via a clamping portion 18. The oil-collecting washer 15 and the damping washer 16 increase the damping of the connection between the damping connection sleeve 10 and the rotary joint 9, allowing the lighting lamp 2 to rotate along the circumferential direction of the damping connection sleeve 10, further improving the adaptability of the rotation angle of the lighting lamp 2.

[0031] The lighting lamp 2 comprises a lamp housing 21, a lamp cover 22, and an LED light board 23 disposed within the lamp housing 21. The lamp cover 22 is snap-fitted to the lamp housing 21 and has an anti-glare film 24 bonded to the interior of the lamp cover 22. The base 1 defines an internal cavity, housing a main control board electrically connected to the LED light board 23. The main control board is also electrically connected to a control switch 17, which is exposed on the base 1. The anti-glare film 24 allows the lighting lamp 2 to rotate at an angle, minimizing the impact of light on the human body.

[0032] The specific uses of this utility model are:

[0033] By matching the rotating connecting shaft 5 with the mounting hole, the rotating connecting shaft 5 can drive the support rod 3 to rotate flexibly on the connecting end 4 to achieve preliminary adjustment of the lighting angle of the desk lamp. The telescopic rod 6 is stretched from the support rod 3 away from the base 1, and the height of the desk lamp can be adjusted as needed to meet the needs of different heights and usage scenarios, thereby improving the applicability and convenience of the desk lamp. The limit connecting seat 7 is plugged into the end of the telescopic rod 6 through the plug-in portion 8. At the same time, the limit connecting seat 7 can rotate along the circumferential direction of the telescopic rod 6 and is locked and fixed by the locking piece 12, further increasing the adjustment range of the lighting angle of the desk lamp. The rotatable rotating joint 9 on the limit connecting seat 7 allows the lighting lamp 2 to rotate freely on the limit connecting seat 7, further enriching the functionality of the desk lamp. The lighting angle adjustment function, the matching plug-in installation of the lighting lamp 2 and the damping connecting sleeve 10, enables the lighting lamp 2 to be firmly installed on the rotary joint 9, and the rotary joint 9 can be flipped along the rotating connection part 13 of the limit connecting seat 7, and the lighting lamp 2 can be rotationally adjusted through the damping connecting sleeve 10, and the connection and use of the oil-collecting gasket 15 and the damping gasket 16 can reduce the accidental shaking of the lighting lamp 2, and further provide the lighting lamp 2 with resistance control during rotation, so that the lighting lamp 2 can stay at any desired position without slipping easily. The user can adjust the lighting lamp 2 to the most comfortable and suitable lighting position according to specific needs, and can conveniently store it by adjusting the rotation angle and the contraction of the telescopic rod, thereby improving the stability and safety of use.
