[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Existing desks are generally designed as a single unit. However, when staff need to handle special tasks, they need to adjust the angle of the desk. The single-unit desk structure makes it inconvenient to flip the desk, which does not provide staff with a good working environment.

[0021] In view of this, the present invention provides a height-adjustable office desk with a flip-top. Through the cooperation between the flip-top, the rotating rod, and the drive wheel, when the user needs to adjust the angle of the desk, the drive wheel can be rotated. The drive wheel drives the rotating rod, the rotating rod drives the gear, and the two gears can drive the connecting shaft to rotate, so that the flip-top can adjust the angle of the desk, allowing the user to have a more comfortable working condition.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example 1: By Figure 1-4 It is known that a height-adjustable office desk with a foldable desktop includes a desktop 1, with a housing 11 on both sides of the bottom of the desktop 1. An adjustment frame 12 is inserted into the inner wall of the housing 11. A flipping device 2 is provided between the desktop 1 and the adjustment frame 12. The flipping device 2 includes: a housing 21, fixedly connected to the top of the adjustment frame 12; a connecting shaft 22, rotatably connected to the inner wall of the housing 21; a flipping plate 23, inserted into the inner wall of the housing 21 and fixedly connected to the connecting shaft 22; a rotating rod 24, which passes through the side walls of the two adjustment frames 12 in sequence via bearings; and a gear 25, fixedly connected to... The connecting shaft 22 is located away from the flip plate 23 at one end; the drive wheel 26 is meshed with the outer wall of the gear 25; the bearing part 27 is located outside the rotating rod 24; the anti-rotation unit 28 is located outside the bearing part 27; wherein, rotating the drive wheel 26 drives the two gears 25 to rotate through the rotating rod 24, causing the gears 25 to drive the connecting shaft 22 to rotate, causing the flip plate 23 to flip the table 1; the outer shell 21 installs the connecting shaft 22 and the flip plate 23; the bearing part 27 stabilizes the rotating rod 24; and the anti-rotation unit 28 fixes the gear 25.

[0024] In the specific implementation process, it is worth noting that the drive wheel 26 is composed of a gear structure that meshes with the gear 25 and a handwheel structure. This makes it convenient to rotate the drive wheel 26 to drive the gear 25 to rotate, thereby adjusting the angle of the flip plate 23 and thus driving the table 1 to complete the angle adjustment.

[0025] Furthermore, the supporting part 27 includes: a mounting cylinder 271, sleeved on the outer wall of the rotating rod 24; a shaft 272, rotatably connected to the inner wall of the mounting cylinder 271; and a flipping member 273, inserted into the inner wall of the mounting cylinder 271, with its bottom fixedly connected to the shaft 272 and its top fixedly connected to the bottom of the tabletop 1; wherein, the mounting cylinder 271 plays a stabilizing role for the rotating rod 24, and the flipping member 273 drives the tabletop 1 to rotate within the inner wall of the mounting cylinder 271 through the shaft 272;

[0026] In the specific implementation process, it is worth noting that the shaft 272 and the connecting shaft 22 are on the same horizontal line. When the flip plate 23 rotates on the inner wall of the outer shell 21 through the connecting shaft 22, the flipping part 273 rotates along with it. When the rotating rod 24 rotates, the mounting cylinder 271 can support the rotating rod 24. When the table 1 is flipped, the flipping part 273 rotates on the inner wall of the mounting cylinder 271 at the same time, which can provide a certain support for the table 1.

[0027] Furthermore, the anti-rotation unit 28 includes: a mounting member 281, fixedly connected to the top of the housing 11; a limiting member 282, sleeved on the outer wall of the mounting member 281 and engaged with the outer wall of the drive wheel 26; and a first spring 283, fixedly connected between the mounting member 281 and the limiting member 282. The mounting member 281 mounts the limiting member 282 and the first spring 283. The limiting member 282 engages with the drive wheel 26 to prevent the drive wheel 26 from rotating. The first spring 283 causes the limiting member 282 to move up and down on the outer wall of the mounting member 281.

[0028] In the specific implementation process, it is worth noting that when the tabletop 1 does not need to be adjusted in angle, the top of the limiting member 282 is engaged with the outer wall of the drive wheel 26 to ensure that the gear 25 will not rotate without rotating the drive wheel 26. When the tabletop 1 needs to be adjusted in angle, the limiting member 282 is squeezed against the first spring 283 to disengage the limiting member 282 from the outer wall of the drive wheel 26, thereby allowing the drive wheel 26 to rotate.

[0029] Specifically, when using this tiltable office desk, rotating the drive wheel 26 drives the gear 25 to rotate, thereby adjusting the angle of the tilting plate 23 and thus adjusting the angle of the tabletop 1. When the tilting plate 23 rotates on the inner wall of the outer casing 21 via the connecting shaft 22, the tilting component 273 rotates along with it. During the rotation of the rotating rod 24, the mounting cylinder 271 can support the rotating rod 24. When the tabletop 1 is tilted, the tilting component 273 rotates simultaneously on the inner wall of the mounting cylinder 271, providing some support for the tabletop 1. When the tabletop 1 does not need to be adjusted, the top of the limiting component 282 is engaged with the outer wall of the drive wheel 26, ensuring that the gear 25 will not rotate when the drive wheel 26 is not rotated. When the tabletop 1 needs to be adjusted, the limiting component 282 is pressed against the first spring 283, causing the limiting component 282 to disengage from the outer wall of the drive wheel 26, thus allowing the drive wheel 26 to rotate.

[0030] Example 2: From Figure 1-4It is known that the adjusting frame 12 is internally equipped with a fixing mechanism 3, which includes: a fixing groove 31, which is provided in multiple places and is opened on the inner wall of the housing 11; an electromagnet 32, which is installed on the inner wall of the adjusting frame 12; a second spring 33, one end of which is fixedly connected to the outer wall of the electromagnet 32; a fixing rod 34, one end of which is inserted into the inner wall of the adjusting frame 12 and fixedly connected to the other end of the second spring 33, and the other end of which passes through the outer wall of the adjusting frame 12 and is inserted into the inner wall of the fixing groove 31; and a wiring hole 35, which is opened on the inner wall of the adjusting frame 12. The electromagnet 32 ​​is compressed by controlling the fixing rod 34 when it is located on the inner wall of the fixing groove 31 and retracts, thereby energizing the electromagnet 32 ​​through the wiring hole 35.

[0031] In the specific implementation process, it is worth noting that the adjustment frame 12 is composed of multiple parts. After the electromagnet 32, the second spring 33 and the fixing rod 34 are installed inside the adjustment frame 12, the adjustment frame 12 is then assembled and inserted into the inner wall of the housing 11. When it is necessary to adjust the height of the table 1, the electromagnet 32 ​​is activated first. The electromagnet 32 ​​generates a magnetic force on the fixing rod 34, causing the fixing rod 34 to detach from the inner wall of the fixing groove 31. Then, the operator manually raises or lowers the table 1. After adjusting to the appropriate height, the electromagnet 32 ​​is turned off. Under the action of the second spring 33, the fixing rod 34 will be re-inserted into the inner wall of the fixing groove 31, fixing the adjustment frame 12 and the housing 11, thus realizing the function of height adjustment. Furthermore, through the wiring hole 35, wires can be connected to supply power to the electromagnet 32.

[0032] Furthermore, a base 13 is fixedly connected to the bottom of the casing 11;

[0033] In the specific implementation process, it is worth noting that the base 13 can make the support structure under the tabletop 1 more stable and increase the contact area with the ground.

[0034] Specifically, based on the above embodiment one, when it is necessary to adjust the height of the tabletop 1, the electromagnet 32 ​​is first activated. The electromagnet 32 ​​generates a magnetic force on the fixing rod 34, causing the fixing rod 34 to detach from the inner wall of the fixing groove 31. Then, the person manually raises or lowers the tabletop 1. After adjusting to a suitable height, the electromagnet 32 ​​is turned off. Under the action of the second spring 33, the fixing rod 34 will be re-inserted into the inner wall of the fixing groove 31, fixing the adjustment frame 12 and the housing 11, thus realizing the function of height adjustment. Through the action of the base 13, the support structure under the tabletop 1 can be made more stable, increasing the contact area with the ground.
