Therefore, they cannot be understood as limitations on the present invention.

[0038] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0039] Please see the attached Figure 1 To the attached Figure 8 The utility model provides a lifting table, comprising a mounting base 1, a table top 2 which is liftably arranged on a side of the mounting base 1 away from the ground, and a table lamp 12 which is rotatably arranged on the table top 2; the mounting base 1 is provided with at least two oppositely arranged table lamps 12; the table lamp 12 is arranged on a side of the table top 2 away from the mounting base 1;

[0040] The height adjustable desk also includes:

[0041] A lifting assembly 300 is provided between the mounting base 1 and the table top 2 and is used to adjust the distance between the table top 2 and the mounting base 1;

[0042] The winding drum 401 is disposed in the lifting assembly 300 and rotates synchronously with the lifting of the lifting assembly 300. A connecting rope 402 is wound around the winding drum 401.

[0043] The slider 403 is slidably mounted on the side of the table top 2 away from the mounting base 1. The end of the connecting rope 402 away from the winding drum 401 is connected to the bottom side of the slider 403 (the side of the slider 403 close to the mounting base 1). The slider 403 is provided with a rotatable telescopic rod 405. The other end of the telescopic rod 405 (the end away from the slider 403) is rotatably mounted on the desk lamp 12.

[0044] The return spring 404 is connected to the mounting base 1 , with one end connected to the slider 403 and the other end connected to the mounting base 1 .

[0045] Please see the attached Figure 1 , Attachment Figure 2 , Attachment Figure 4 and attached Figure 6 In a specific implementation of this embodiment, a receiving groove (not shown in the figure) is provided on a side of the table top 2 away from the mounting base 1;

[0046] The slider 403 is disposed in the receiving groove;

[0047] When the desk lamp 12 is in the fully engaged state (in the stowed state), the upper end surface of the desk lamp 12 is at the same horizontal height as the end surface of the table top 2 away from the mounting base 1 (the two end surfaces coincide), and the reset spring 404 is in a natural state (neither stretched nor compressed) or a compressed state.

[0048] In a specific implementation of this embodiment, the desk lamp 12 includes a first section and a second section that are rotatably connected, and the lighting area (light-emitting area) of the desk lamp 12 is arranged on a side of the first section and / or the second section close to the mounting base 1;

[0049] One end of the first section away from the second section is rotatably connected to the table top 2 via a hinge, and the end of the first section away from the second section and the concave area of ​​the table top 2 are combined to form a receiving groove;

[0050] One end of the telescopic rod 405 away from the slider 403 is connected to the side of the first section facing toward the mounting base 1 .

[0051] In a specific implementation of this embodiment, the color temperature and brightness of the lighting area of ​​the desk lamp 12 can be manually adjusted.

[0052] It should be noted that the winding drum 401 , the connecting rope 402 , the slider 403 and the return spring 404 together constitute the synchronous adjustment assembly 400 .

[0053] In practice, when the height of the lifting table needs to be changed (adjusting the height of the table top 2), the lifting assembly 300 is activated. As the lifting assembly 300 rises and falls, the cable reel 401 disposed within the lifting assembly 300 rotates synchronously. When the table top 2 rises, the cable reel 401 rotates synchronously and pulls the slider 403, via the connecting rope 402, in a direction parallel to the table top 2 toward the edge of the table top 2 (towards the first section). The return spring 404 changes from a compressed or natural state to a stretched state. The table lamp 12 is gradually adjusted in height (gradually increasing in height) by the push of the telescopic rod 405. Similarly, when the table top 2 is lowered, the cable reel 401 rotates in the opposite direction, gradually releasing the connecting rope 402. The stretched return spring 404, now in a stretched state, relies on its own elastic force to drive the slider 403 to slide in a direction parallel to the table top 2 toward the edge of the table top 2 (away from the first section). The telescopic rod 405 pulls the table lamp 12, thereby lowering its height.

[0054] This solution is better adapted to the needs of different groups of people. The setting can synchronously adjust the lighting height of the desk lamp 12 according to the height of the table board 2, giving users a better lighting experience and better helping people study and work.

[0055] In a specific implementation of this embodiment, the recessed depths of the receiving grooves (the distance between the bottom of the receiving groove and the mounting base 1 ) are the same.

[0056] In another specific implementation of this embodiment, the recessed depth of the receiving groove (the distance between the bottom of the receiving groove and the mounting base 1 ) is different;

[0057] The depth of the recess on the side of the receiving groove close to the edge of the table top 2 is greater than or less than the depth of the recess on the side of the receiving groove away from the edge of the table top 2 .

[0058] Please see the attached Figure 2 , Attachment Figure 6 and attached Figure 7 In a specific implementation of this embodiment, the slider 403 is further provided with a manual adjustment component 500 for manually adjusting the angle of the desk lamp 12, including:

[0059] The connecting base 505 is rotatably connected to the slider 403. The connecting base 505 is detachably connected to the mounting base 504 via a pin. The other side of the mounting base 504 is rotatably connected to the telescopic rod 405.

[0060] The positioning bolt 502 is threadedly connected to the telescopic rod 405. The telescopic rod 405 has a plurality of positioning holes 503 arranged in a linear array along the length direction, which are adapted to the positioning bolt 502.

[0061] A plurality of limiting grooves 501 are distributed in a linear array along the length direction of the mounting base 1 , and the limiting grooves 501 are adapted to the telescopic rod 405 .

[0062] In specific implementation, when the desk lamp 12 is not needed for lighting during the day, there is no need to turn on the desk lamp 12. The mounting base 504 can be removed from the connecting base 505 to avoid lifting and lowering while the height of the desk lamp 12 is also adjusted synchronously. Relatively speaking, the user can also use the extracted mounting base 504 in conjunction with the limiting groove 501 to manually adjust the height of the desk lamp 12, or by lengthening the length of the telescopic rod 405 and fixing the length of the telescopic rod 405 by using the positioning bolt 502 in conjunction with the positioning hole 503, so as to more accurately adjust the height of the desk lamp 12 to the required level.

The driving end of the servo motor 302 is connected to a transmission screw 303. A transmission interference block 304 is threadedly connected to the transmission screw 303. The other end of the transmission interference block 304 is connected to the bottom of the lifting block 305.

[0065] In practice, the servo motor 302 is first activated to rotate the transmission screw 303. The height of the lifting block 305 is then adjusted via the transmission resistance block 304 during the rotation of the transmission screw 303, thereby adjusting the height of the table top 2. This design utilizes the transmission screw 303 for adjustment, making it easy to adjust and lock at any time, resulting in a better height adjustment effect.
