[0024] Example 1

[0025] like Figure 1 to Figure 6 As shown, this embodiment proposes an adjustable office desk, including two base plates 1, the tops of the two base plates 1 are fixedly connected with sleeves 11 and 12, the interior of the sleeves 11 is provided with lifting rods 2, the interior of the sleeves 12 is slidably connected with telescopic rods 21, the tops of the two lifting rods 2 are commonly fixed with a flat plate 22, the tops of the telescopic rods 21 are rotatably connected to the lower surface of the flat plate 22, one side of the flat plate 22 is rotatably connected with an extension plate 23, the outer side walls of the telescopic rods 21 are fixedly connected with upper slide rails 24, the outer side walls of the upper slide rails 24 are slidably sleeved with lifting blocks 25, the side walls of the lifting blocks 25 are rotatably connected with upper protrusions 26, one end of the upper protrusions 26 penetrates the side walls of the lifting blocks 25 and extends to the interior of the upper slide rails 24, and a connecting rod 27 is rotatably connected between the lifting blocks 25 and the extension plates 23.

[0026] A lower rail 3 is fixedly connected to the inner wall of the sleeve 2 12, and a lower protrusion 31 is fixedly connected to the bottom end of the telescopic rod 21. The lower protrusion 31 is slidably connected to the inside of the lower rail 3, and is slidably connected to the inside of the lower rail 3 through the lower protrusion 31. When the telescopic rod 21 slides upward, the lower rail 3 can control the telescopic rod 21 to rotate through the lower protrusion 31; a motor 4 is fixedly connected to the inner bottom wall of the sleeve 11, and a rotating drum 41 is rotatably connected to the inner wall of the sleeve 11. The output end of the motor 4 is fixedly connected to the bottom of the rotating drum 41, and the rotating drum 41 is threadedly sleeved on the outer wall of the lifting rod 2. By starting the motor 4, the motor 4 can drive the rotating drum 41 to rotate through the output end, and the rotating drum 41 can control the use height of the flat plate 22 through the lifting rod 2; a through hole is provided on the outer wall of the lifting block 25 Hole 6, the upper protrusion 26 is threadedly sleeved on the inner wall of the through hole 6, and is threadedly connected to the through hole 6 through the upper protrusion 26. By rotating the upper protrusion 26, it is convenient to control the position of the upper protrusion 26 on the upper slide rail 24; a pair of fixed blocks 5 are fixedly connected to the outer side walls of the lifting block 25 and the extension plate 23, and the lifting block 25 and the extension plate 23 are rotatably connected to the connecting rod 27 through the same pair of fixed blocks 5, and are rotatably connected between the same pair of fixed blocks 5 through the connecting rod 27. During the upward movement of the lifting block 25, it is convenient for the lifting block 25 to drive the extension plate 23 to rotate upward through the fixed block 5 and the connecting rod 27; the end of the upper protrusion 26 away from the upper slide rail 24 is fixedly connected with a turning handle 7, and the upper protrusion 26 is rotated by rotating the turning handle 7, which is convenient to control the position of the upper protrusion 26 inside the through hole 6.

[0027] In this embodiment, when a larger tabletop area is needed, the motor 4 is started, and the motor 4 drives the rotating drum 41 to rotate inside the sleeve 11 through the output end. Under the common limiting action of the lifting rod 2 and the telescopic rod 21, the rotating drum 41 drives the lifting rod 2, the flat plate 22 and the telescopic rod 21 to move vertically upward. Under the limiting action of the lower slide rail 3, the telescopic rod 21 rotates along the inner side wall of the lower slide rail 3 through the lower protrusion 31, and the telescopic rod 21 drives the upper slide rail 24 to rotate. Under the limiting action of the upper slide rail 24, the upper slide rail 24 drives the lifting block 25 to slide upward along the upper slide rail 24 through the upper protrusion 26, and the lifting block 25 is connected to the lifting block 25. The rod 27 drives the extension plate 23 to rotate upward. After the side of the extension plate 23 and the flat plate 22 are close to each other, the lower protrusion 31 moves to the middle of the lower slide rail 3. Under the limiting effect of the lower slide rail 3, the telescopic rod 21 is prevented from rotating, so that the position of the lifting block 25 on the upper slide rail 24 is fixed. The rotating drum 41 continues to drive the flat plate 22 and the extension plate 23 to move upward, and the flat plate 22 and the extension plate 23 are adjusted to the use height. By splicing the flat plate 22 and the extension plate 23 together, the flat plate 22 and the extension plate 23 are used at the same time, thereby increasing the use area of ​​the desktop. The adjustment steps are simple and convenient, which is convenient for users to adjust the office desk.

[0028] When a smaller tabletop area is needed, the handle 7 is rotated, which drives the upper protrusion 26 to move along the through hole 6 toward the outside of the through hole 6, so that the upper protrusion 26 is separated from the upper slide rail 24, and the limit of the upper slide rail 24 on the upper protrusion 26 is released, and the motor 4 is started. The motor 4 drives the rotating drum 41 to rotate inside the sleeve 11 through the output end. Under the joint limiting action of the lifting rod 2 and the telescopic rod 21, the rotating drum 41 drives the lifting rod 2, the flat plate 22 and the telescopic rod 21 to move vertically upward. Under the action of gravity, the lifting block 25 is always located at the bottom of the upper slide rail 24. The lifting block 25 limits the extension plate 23 through the connecting rod 27, so that the extension plate 23 always remains in a vertical state. The flat plate 22 is adjusted to the use height by rotating the rotating drum 41. By placing the extension plate 23 on one side of the flat plate 22, the flat plate 22 is used alone, thereby reducing the use area of ​​the desktop. The adjustment steps are simple and convenient, which is convenient for users to adjust the office desk.

[0029] Example 2

[0030] like Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a pair of hinges 8 are fixedly connected to one side of the flat plate 22 close to the extension plate 23, and the flat plate 22 is rotatably connected to the extension plate 23 through the pair of hinges 8.

[0031] In this embodiment, the extension plate 23 is rotatably connected to the flat plate 22 via a pair of hinges 8. When the lifting block 25 slides upward along the upper slide rail 24, the lifting block 25 drives the extension plate 23 to rotate around the hinge 8 via the fixed block 5 and the connecting rod 27, so that the side of the extension plate 23 and the flat plate 22 that are close to each other fits together, rotates smoothly, and occupies less space.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
