Description

Technical Field

[0001] The utility model relates to the technical field of lighting appliances, in particular to an adjustable table lamp. Background Art

[0002] Table lamps are household appliances used for lighting in people's lives. They are generally divided into two types, one is a column type and the other is a clamp type. Its working principle is mainly to concentrate the light in a small area, which is convenient for work and study. Generally, table lamps are composed of two parts, light source and lamps. The light source is an incandescent lamp, energy-saving lamp, halogen lamp, LED lamp, etc. The lamp is composed of a lampshade, a lamp pole, a base, and an internal driving circuit.

[0003] According to an angle-adjustable eye-protection desk lamp disclosed in announcement number CN215722699U, desk lamps in the prior art have a fixed posture and a single irradiation direction, and cannot obtain the same and good light in different postures. Reading or working in an environment with insufficient brightness for a long time can easily damage the eyes. To address such problems, this product has designed a set of regulators in the desk lamp, through which the height and irradiation angle of the desk lamp can be freely adjusted, so that a better experience can be obtained when reading or working in various postures, and the eyes will not be damaged due to reading or working in insufficient light.

[0004] However, when the above device is in use, the regulator is designed to adjust the tilt angle of the desk lamp stand. In actual use, due to different reading postures of users, different irradiation angles of the desk lamp are required, and the desk lamp regulator on the above device tilts the desk lamp stand, and the irradiation angle of the lamp head is fixed. Therefore, the lamp head will tilt with the lamp stand, and the lamp head cannot rotate freely according to the user's reading requirements. When the user needs to adjust the lamp stand due to the position of the book, the desk lamp cannot irradiate at the original position, resulting in certain limitations. In order to solve this problem, we propose an adjustable desk lamp. Utility Model Content

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0035] See also Figure 1-3An adjustable desk lamp includes a desk lamp 1, wherein the desk lamp 1 includes: a base 11, a bracket 12 is arranged on the top of the base 11, the bracket 12 is arranged at the center of the base 11 and the bracket 12 and the base 11 are fixedly connected; an adjustment device 2 is arranged on the desk lamp 1, and the adjustment device 2 includes: a rotating component 21, which is arranged on the bracket 12, and the rotating component 21 and the lamp holder 22 are rotatably connected; a fixing block 23, which is arranged on the top of the lamp holder 22, and the fixing block 23 and is rotatably connected to the lampshade 13; a fixed block 24 is arranged on the back of the lampshade 13, and the fixed block 24 is rotatably connected to the lampshade 13; a sliding rod 27 is arranged on the lamp holder 22, and the sliding rod 27 is slidably connected to the lamp holder 22, and a fixed block 3 26 is arranged on the sliding rod 27; a rod body 25 is arranged on the fixed block 24 and the fixed block 3 26, and the two ends of the rod body 25 are rotatably connected to the fixed block 24 and the fixed block 3 26 respectively. When using the desk lamp 1, the user needs to adjust the illumination angle or placement of the desk lamp 1 according to his or her own behavior habits or the illumination angle required at the moment. The bracket 12 is arranged at the center position of the base 11, which is beneficial to improving the stability of the entire bracket 12 and the components on the bracket 12. The user adjusts the inclination angle of the lamp frame 22 by using the rotating component 21. After the inclination angle of the lamp frame 22 is adjusted, the angle of the lampshade 13 needs to be adjusted accordingly to ensure that the illumination position of the light remains original. The user twists the second threaded member 271 to loosen the sliding rod 27, and then manually controls the sliding rod 27 on the lamp frame through the sliding rod 27. 22 is lifted up and down, and the user moves the sliding rod 27 downward, and the sliding rod 27 drives the fixed block three 26 to move downward synchronously. The fixed block three 26 is rotatably connected to the rod body 25, and the rod body 25 is rotatably connected to the fixed block two 24. Therefore, under the pushing action of the rod body 25, the lower end of the lampshade 13 is lifted up and tilted upward. At the same time, the top of the lampshade 13 is rotatably connected to the fixed block one 23. Therefore, the lampshade 13 rotates with the fixed block one 23 as the fulcrum under the pushing action of the bottom to adjust its own angle. Conversely, the sliding rod 27 can be lifted up to reset the lampshade 13. After adjusting the position, screw the screw part two 271 to fix the lampshade 13.

[0036] The base 11 is provided with a counterweight 28, and the weight of the counterweight 28 is consistent with the total weight of the lamp stand 22 and the components on the lamp stand 22. The lamp stand 22 is provided with a slide groove that is slidably connected with the sliding rod 27. The outer surface of the sliding rod 27 is provided with an external thread, and the sliding rod 27 passes through the extended part of the lamp stand 22 and is threadedly connected with a threaded member 271. The threaded member 271 is a butterfly bolt. By providing the counterweight 28, the position of the counterweight 28 and the lamp stand 22 are respectively provided at both ends of the bracket 12, so as to ensure the balance of the entire device, prevent the device from tilting, and improve the stability of the entire device. When the slide groove provided on the lamp stand 22 slides with the sliding rod 27, the opening of the slide groove on the lamp stand 22 is smaller than the width of the fixed block 3 26, so that the fixed block 3 26 can be prevented from falling into the slide groove, affecting the use of the entire device. The threaded member 271 is a butterfly bolt, and butterfly fixing plates are provided at both ends, which can provide a fulcrum for the user, making it convenient and labor-saving to use, and improving the user's experience. Example

[0037] On the basis of the first embodiment, a function of adjusting the angle of the lamp stand is added.

[0038] See also Figure 1-3 The rotating assembly 21 includes: a rotating shaft 211, which is arranged on the bracket 12, the rotating shaft 211 is rotatably connected with the bracket 12, and the rotating shaft 211 is fixedly connected with the lamp holder 22; a threaded member 212, which is arranged at the other end of the rotating shaft 211. The rotating shaft 211 is provided with an external thread, and the threaded member 212 is provided with an internal thread, and the rotating shaft 211 and the threaded member 212 are threadedly connected. When the user needs to adjust the inclination angle of the lamp holder 22 to change the overall state of the table lamp 1, the threaded member 212 is loosened by twisting the threaded member 212 counterclockwise, so that the rotating shaft 211 can be controlled to drive the lamp holder 22 to rotate, thereby adjusting the inclination angle of the lampshade 13 on the lamp holder 22, so that the irradiation angle of the bulb inside the lampshade 13 is changed, and the angle adjustment assembly of the lampshade 13 is used to increase the diversity of the angle adjustment of the entire device, and improve the functionality and flexibility of the entire device.
