[0021] The present utility model will be further described in detail below in conjunction with the accompanying drawings. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "upper, lower" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary instructions, these orientation words do not indicate or imply that the devices or elements referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model; the orientation words "inner, outer" refer to the inside and outside relative to the contour of each component itself.
[0022] As Figures 1-5 shown, a table lamp includes a base 1, a lamp arm 2, a lampshade 3, a lamp socket 4 and a bulb 5. The bulb is installed on the lamp socket.
[0023] The lamp arm includes a main body section 6 and a mounting section 7. The main body section and the mounting section are provided with wire passing holes. The lower end of the main body section is connected to the base through a lamp arm adjustment structure; the mounting section is U-shaped and the two ends of the mounting section bend inward and extend. The two ends of the lampshade are connected to the mounting section through a lampshade adjustment structure; the lampshade is an opaque lampshade, and the lampshade includes a semi-cylindrical portion and an extension portion extending outward along the semi-cylinder. The lamp socket is coaxially arranged with the semi-cylindrical portion of the lampshade.
[0024] In this way, when it is necessary to adjust the irradiation height and angle, the height of the bulb is adjusted through the lamp arm adjustment structure, and then the irradiation height is adjusted. Through the lampshade adjustment structure, the angle of the lampshade is adjusted, and then the irradiation angle is adjusted. During the adjustment process, a large range of angle adjustment can be achieved by rotating the lampshade. The lampshade adopts a semi-cylindrical portion and an extension portion extending outward along the semi-cylinder, which can better concentrate the light.
[0025] During implementation, the lamp arm adjustment structure includes a support 13 fixedly installed on the base and a first damping rotating shaft 11. A connecting head 12 is fixed at the lower end of the main body section of the lamp arm. The support and the connecting head are both provided with grooves. The two ends of the first damping rotating shaft are respectively located in the grooves of the support and the connecting head and are fixedly connected to the support and the connecting head. The first damping rotating shaft is provided with a through hole along its axis. The support and the connecting head are provided with wire passing holes.
[0026] In this way, through the setting of the first damping rotating shaft, it is convenient for the lamp arm to rotate relative to the base and be fixed at a corresponding angle.
[0027] During implementation, it further includes a connecting ring 14. The connecting ring is fixedly connected to a bent pipe 15, and the bent pipe is fixedly connected to the base. The connecting ring, the support and one end of the first damping rotating shaft are fixedly connected by bolts, and the other end of the first damping rotating shaft is fixedly connected to the connecting head by bolts.
[0028] In this way, a circuit board is installed inside the base. After the circuit passes through the base, it reaches the lamp arm position through the elbow pipe and the connecting ring. The arrangement of the connecting ring and the elbow pipe facilitates shading of the circuit. A switch electrically connected to the circuit board is also installed on the base.
[0029] During implementation, the lamp shade adjustment structure includes a second damping rotating shaft 21, an inner disc 22, an outer disc 23 and a plug pin 24. The outer disc is connected to the plug pin through the second damping rotating shaft. A jack 25 that is inserted and matched with the plug pin is provided on the installation section of the lamp arm. The plug pin is inserted and matched with the jack. The inner disc is fixedly connected to the lamp base. The inner disc and the outer disc are respectively located inside and outside the lamp shade. The inner disc, the lamp disc and the outer disc are fixedly connected by bolts. The inner disc and the outer disc at one end of the lamp base are fixedly connected by bolts. Through holes for wires are provided through the inner disc, the outer disc, the lamp shade and the plug pin. The second damping rotating shaft and the plug pin are provided with through holes along the axis.
[0030] In this way, through the arrangement of the second damping rotating shaft, it is convenient to rotate the lamp shade and fix it at a corresponding angle.
