Description
Technical Field
[0001] This utility model relates to the field of height-adjustable desks, and in particular to a single-leg height-adjustable desk that can be flipped over. Background Technology
[0002] Height-adjustable desks, as work surface devices, are widely used in office, study, meeting, and medical settings. Their main function is to adjust the desktop height to accommodate different user sitting or standing postures, thereby improving comfort and ergonomics. To further enhance functionality, some models incorporate a desktop flipping mechanism, allowing the desktop to rotate within a certain angle to meet diverse usage needs such as presentations, drawing, and projection.
[0003] Currently, most height-adjustable desks on the market use a double-leg structure, achieving desktop tilting through a base at the bottom and a tilting cylinder mechanism. While this type of structure provides a certain degree of tilting capability, it also has the following problems: On the one hand, the tilted cylinder requires precise control of its angle and the positioning of its connectors during installation, which not only increases assembly difficulty but also raises manufacturing costs. On the other hand, the cylinder's force direction is inconsistent with the table's center of gravity, easily causing uneven loading and reducing the overall structural stability. Furthermore, the cylinder mechanism protrudes from the bottom of the table, occupying limited installation space, affecting the layout of other components, and potentially interfering with table legs, wiring systems, or the user's lower limbs during use, posing a risk of collision.
[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] like Figures 1 to 10 As shown: A flip-up single-leg height-adjustable table includes: a first desktop 1, a second desktop 2, a lifting column 3, a lifting assembly 5 for driving the first desktop 1 and the second desktop 2 to rise and fall, and a flipping assembly 6 for driving the second desktop 2 to flip. The lifting assembly 5 includes an L-shaped connector 51 disposed at the bottom of the first desktop 1 for connecting the lifting column 3 and the first desktop 1. The L-shaped connector 51 is fixed to the bottom of the first desktop 1. The lifting column 3 is equipped with a cylinder 31 and is connected to the first operating lever 52 for controlling the extension and retraction of the cylinder 31. The flipping assembly 6 includes a brake member disposed on the side of the L-shaped connector 51 and a second connector 61 disposed on the bottom of the second desktop 2; The braking component includes a locking mechanism 62, a pulling member 63, a connecting line 64, and a second operating lever 65, as well as a second rotating shaft 621 passing through the interior of the locking mechanism 62. The pulling member 63 is disposed on the side of the braking component and is connected to the second rotating shaft 621. One end of the connecting line 64 is connected to the pulling member 63, and the other end is connected to the second operating lever 65. By moving the second operating lever 65, the connecting line 64 drives the pulling member 63 and the second rotating shaft 621 to rotate, thereby releasing the locking mechanism 62 from locking the second tabletop 2 and enabling the second tabletop 2 to rotate along the axis of the second rotating shaft 621.
[0024] In use, the first operating lever 52 is moved to drive the cylinder 31 to lift the lifting column 3, thereby causing the first desktop 1 and the second desktop 2 to lift synchronously; the second operating lever 65 is moved to drive the connecting wire 64 to pull the puller 63 and the second rotating shaft 621 to rotate, thereby releasing the locking mechanism 62 and allowing the second desktop 2 to rotate along the axis of the second rotating shaft 621. After releasing the lever, the locking mechanism 62 automatically locks and relocks, allowing the desktop to be positioned after rotating at any angle.
[0025] The first operating lever 52 controls the cylinder 31 in the lifting assembly 5 to lift and lower, thereby achieving synchronous lifting and lowering of the first desktop 1 and the second desktop 2; the second operating lever 65 controls the flipping assembly 6 to achieve the flipping action of the second desktop 2. The two components are structurally independent and have clear control, allowing users to operate them separately as needed, thus improving the flexibility of use.
[0026] The braking component in the flip assembly 6 is located on the side of the L-shaped connector 51, and the flipping mechanism is distributed in the bottom edge area of the desktop. This effectively avoids the leg space interference problem caused by the traditional tilting cylinder 31 structure and improves the space utilization of the bottom of the desktop. Through the setting of the locking mechanism 62, the second desktop 2 is automatically locked after flipping. It can maintain the stable positioning of the desktop at any angle without additional fasteners, preventing the desktop from accidentally flipping due to gravity or external force, and improving the safety of use.
[0027] The flip component 6 rotates around the second pivot 621. Its simple structure is not limited by the stroke of the traditional cylinder 31 and can achieve free flipping within a wider angle range, meeting the different needs of various usage scenarios such as drawing, presentation, and reading for different desktop angles.
[0028] The lifting column 3 includes an inner tube and an outer tube. The inner tube moves up and down along the inside of the outer tube under the drive of the cylinder 31, thereby realizing the lifting of the tabletop. This is existing technology and will not be described in detail here.
[0029] As a preferred embodiment of the above, the locking mechanism 62 includes an irregularly shaped cam 622, a slider 623, an annular wheel 624, and a coil spring 625; The irregular cam 622 is mounted on the second rotating shaft 621 and rotates along the axis of the second rotating shaft 621. The cross section of the irregular cam 622 has multiple protrusions 622a along the circumferential direction. The annular wheel 624 and the irregular cam 622 are coaxially arranged. The inner ring of the annular wheel 624 is provided with a number of first teeth 624a. Multiple sliders 623 are arranged inside the annular wheel 624 and correspond one-to-one with the positions of the protrusions 622a. The end of the slider 623 is provided with a second tooth 623a that meshes with the first tooth 624a. The rotation of the irregular cam 622 drives the multiple sliders 623 to retract towards the side closer to the second rotating shaft 621, so that the second tooth 623a moves away from the first tooth 624a. One end of the coil spring 625 is provided on the second rotating shaft 621 and the other end is provided on the annular wheel 624, which is used to reset the irregular cam 622 and the sliders 623.
[0030] In normal conditions, the second tooth 623a on the slider 623 engages with the first tooth 624a of the annular wheel 624, thereby locking the second tabletop 2 after it is flipped to any angle to prevent accidental rotation.
[0031] When it is necessary to adjust the flip angle of the second tabletop 2, the second operating lever 65 is operated, which drives the puller 63 through the connecting line 64, thereby driving the second rotating shaft 621 and the irregular cam 622 on it to rotate. As the irregular cam 622 rotates, its protrusion 622a pushes the slider 623 to retract radially inward, causing the second tooth 623a on the slider 623 to disengage from the first tooth 624a, thereby releasing the locked state and allowing the second tabletop 2 to rotate around the second rotating shaft 621.
[0032] After the second operating lever 65 is released, the irregular cam 622 automatically resets under the elastic force of the coil spring 625, and the slider 623 returns to its initial position, so that the second tooth 623a re-engages with the first tooth 624a, thereby locking the second tabletop 2 again and ensuring that it remains stable after being flipped to any angle.
[0033] The engagement of the gears is controlled by the shaped cam 622 and the slider 623, achieving mechanical locking and releasing. It can be precisely locked after the second desktop 2 is flipped to any angle, improving the flexibility of the flipping function and the accuracy of desktop positioning, and meeting the actual needs of users for multi-angle adjustment. A coil spring 625 is set to drive the shaped cam 622 to reset, which can automatically restore the locking structure after the user releases the operating lever, without manual assistance, reducing the risk of misoperation and improving the safety of use.
[0034] In this embodiment, the flipping assembly 6 further includes a limiting baffle 66 and a limiting member 67; One end of the limiting baffle 66 is connected to the locking mechanism 62, and the other end is connected to the second connecting member 61, and the limiting member 67 is provided with an arc-shaped groove 661; The limiting member 67 passes through the arc groove 661 and is disposed on the L-shaped connector 51, and the limiting member 67 slides along the arc groove 661 to limit the flip angle range of the second desktop 2.
[0035] As a preferred embodiment of the above, the length of the arc groove 661 is within ±45°, the arc segment is set downward, and the length of the arc segment ends at ±45°, so that the maximum flip angle of the desktop is ±45°. Of course, the arc groove 661 can also be of other length ranges, all of which are within the protection scope of this application.
[0036] As a preferred embodiment of the above embodiment, the top of the limiting baffle 66 is provided with a protrusion 662; The second connector 61 includes a horizontal part 611 fixedly disposed with the second desktop 2 and a vertical part 612 disposed perpendicularly to both sides of the horizontal part 611. The horizontal part 611 is provided with a positioning groove 611a, the protrusion 662 is inserted into the positioning groove 611a, and the two sides of the limiting baffle 66 abut against the inner side of the vertical part 612 respectively, so that the limiting baffle 66 is fixed, effectively preventing the limiting baffle 66 from shaking or swinging during use, and improving the rigidity and stability of the limiting structure.
[0037] As a preferred embodiment of the above, the braking component further includes a housing 68 disposed outside the limiting baffle 66 to prevent dust from entering and to ensure the service life of the internal parts.
[0038] As a preferred embodiment of the above embodiment, the pulling member 63 includes a fixing part 631 and a pulling part 632; The fixing part 631 has a circular plate structure and is fixedly installed with the second rotating shaft 621; The pulling part 632 extends radially along the fixing part 631 to form a straight section 623a, and a bending section 623b is provided along one side of the straight section 623a. The bending section 623b is perpendicular to the straight section 623a. One end of the pulling part 632 is provided with an L-shaped groove 624c, the opening of the L-shaped groove 624c is located on the straight section 623a, and the end extends to the bending section 623b; A post 641 is provided at the end of the connecting wire 64. The connecting wire 64 is placed in the L-shaped groove 624c. When the connecting wire 64 is under force, the pulling part 632 is rotated along the second rotating shaft 621. During installation, the connecting wire 64 is slid to the bottom of the L-shaped groove 624c and tightened. The post 641 is larger than the width of the L-shaped groove 624c, so the end of the connecting wire 64 can be quickly installed into the L-shaped groove 624c. This prevents the connecting wire 64 from coming out, realizes the quick insertion and stable installation of the connecting wire 64, simplifies the assembly operation, and improves the connection reliability.
[0039] The L-shaped connector 51 is hollow inside, and a first rotating shaft 511 is provided in the width direction of the L-shaped connector 51. A bushing 512 is provided on the first rotating shaft 511. The first operating lever 52 includes a pressing part 521 and a force-applying part 522 at both ends, and a connecting section 523 for connecting the pressing part 521 and the force-applying part 522. The connecting section 523 is inclined and passes through the bottom of the bushing 512. The force-applying part 522 is connected to the pin at the end of the cylinder 31 for driving the cylinder 31 to extend and retract. Specifically, when the pressing part 521 is subjected to upward force, the connecting part rotates along the bushing 512 under the prying action of the bushing 512, causing the force-applying part 522 to move downward, the cylinder 31 to unlock, and the lifting column 3 to rise and fall.
[0040] In this embodiment, a base 4 is provided at the bottom of the lifting column 3, and rollers 41 are provided at the bottom of the base 4, so that the entire lifting table can move flexibly on the ground, making it convenient for users to adjust the position according to their needs and improving the flexibility of use.
[0041] As a preferred embodiment, a baffle 21 is provided on the side of the second desktop 2. The baffle 21 has an L-shaped cross-section. A mounting hole 211 is provided on the side of the baffle 21 closest to the second desktop 2. The mounting hole 211 has a keyhole-like structure, including a wide circular portion at one end and a narrow straight groove portion communicating with it. When disassembling, the baffle 21 can be removed by slightly loosening the locking member and pushing the baffle 21 along the length direction. The installation and removal of the baffle 21 can be realized without completely disassembling the locking member, which effectively avoids the loss of small parts.
