Description

Technical Field

[0001] This utility model relates to the field of height-adjustable desks, and in particular to a flip-up height-adjustable desk. Background Technology

[0002] A flip-up height-adjustable desk is a multi-purpose piece of furniture that combines height adjustment and desktop flipping functions. In recent years, it has been increasingly used in office, home, and educational settings. These products achieve flexible desktop height adjustment through a lifting mechanism, meeting the health needs of users who alternate between sitting and standing postures. At the same time, its flipping function can switch the desktop to a vertical or folded state, effectively saving space and expanding usage scenarios.

[0003] Currently, however, most existing products use complex mechanical structures that require precise parts to achieve tabletop flipping. These complex structures not only increase the difficulty of manufacturing but also increase production costs.

[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. Utility Model Content

[0005] This invention provides a flip-up and height-adjustable table, thereby effectively solving the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a flip-up and height-adjustable table, comprising: a tabletop, table legs, and a flipping component disposed between the tabletop and the table legs;

[0007] The flipping component includes a first connector disposed at the bottom of the tabletop and a second connector disposed at the top of the table leg;

[0008] The first connector includes a horizontal portion parallel to the desktop, and vertical portions perpendicular to both sides of the horizontal portion. The two vertical portions and the horizontal portion form a receiving space, and the second connector is disposed within the receiving space.

[0009] A rotating component is provided between one end of the second connector and the vertical part. A damping pad is fitted on the rotating component located between the first connector and the vertical part. The second connector rotates along the rotating component. A spring pin component is provided at the end of the vertical part away from the rotating component for locking or releasing the second connector.

[0010] Furthermore, the spring-loaded assembly includes a base, a spring-loaded pin, and a spring;

[0011] The base is disposed on the vertical part and includes a first through hole and a blind hole that are interconnected, wherein the diameter of the blind hole is larger than the diameter of the first through hole;

[0012] The spring pin includes a first diameter segment in the middle and second and third diameter segments on both sides. The diameter of the first diameter segment is larger than the diameters of the second and third diameter segments. The spring is sleeved on the second diameter segment, which passes through the blind hole and the first through hole. One end of the spring contacts the bottom of the blind hole, and the other end contacts the side of the first diameter segment. The spring pin moves within the blind hole under force. The spring is used to reset the spring pin, so that the third diameter segment is close to the positioning hole of the second connector.

[0013] Furthermore, the end of the third diameter segment is provided with a guide angle.

[0014] Furthermore, the outer circular surface of the third diameter segment is tapered, and the diameter gradually increases on the side closer to the first diameter segment.

[0015] Furthermore, the spring pin assembly also includes a handle connected to the second diameter segment.

[0016] Furthermore, the base is provided with a protrusion, which is inserted into the through hole of the vertical part, and a fixing member is provided between the base and the vertical part.

[0017] Furthermore, the rotating assembly includes a pull nut and a screw threaded into it. The pull nut is disposed in a mounting hole in the side wall of the second connector, and the screw threaded into it passes through the mounting hole of the vertical part and is screwed into the pull nut.

[0018] Furthermore, the rotating assembly includes a rotating shaft that passes through the first connector and the two vertical portions.

[0019] Furthermore, foam is provided on the bottom side of the first connector away from the rotating assembly.

[0020] Furthermore, the table leg includes an inner tube, an outer tube, and a locking element located at the corner of the outer tube;

[0021] The locking component includes a housing disposed on the outer tube, a movable block disposed inside the housing, and an adjusting component partially disposed inside the housing. The movable block has mutually perpendicular pressing surfaces on the side near the inner tube, and an elastic body is disposed on the pressing surface.

[0022] One end of the adjusting component is a cam structure, and the other end is an arc-shaped structure. A rotating shaft is provided between the cam structure and the housing, and the rotating shaft is eccentrically set with respect to the cam structure. Rotating the arc-shaped structure causes the cam structure to rotate along the rotating shaft, thereby driving the movable block to move within the housing.

[0023] The beneficial effects of this utility model are as follows: This utility model achieves the flipping and storage of the desktop by pulling the elastic component outward and pushing the desktop along the rotating component to a vertical distance; when the desktop needs to be unfolded, the vertical desktop is rotated in the opposite direction to the horizontal, at which time the second connector is located in the receiving space of the first connector. After releasing, the end of the spring pin component automatically extends into the mounting hole of the second connector to fix the horizontal position of the desktop. This avoids complex mechanical structures and redundant parts, making the entire flipping system simpler and more efficient, and reducing manufacturing and installation costs.

[0033] 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.

[0034] In the description of this utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0035] 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.

[0036] like Figures 1 to 7 As shown: A flip-up and height-adjustable table includes: a tabletop 1, table legs 2, and a flipping assembly 3 disposed between the tabletop 1 and the table legs 2;

[0037] The flipping component 3 includes a first connector 31 disposed at the bottom of the tabletop 1 and a second connector 32 disposed at the top of the table leg 2;

[0038] The first connector 31 includes a horizontal part 311 parallel to the tabletop 1, vertical parts 312 on both sides of the horizontal part 311, the two vertical parts 312 and the horizontal part 311 form an accommodating space, and the second connector 32 is disposed in the accommodating space.

[0039] A rotating component 33 is provided between one end of the second connector 32 and the vertical part 312. A damping pad 34 is fitted on the rotating component 33 located between the first connector 31 and the vertical part 312. The second connector 32 rotates along the rotating component 33. A spring pin component 35 is provided at the end of the vertical part 312 away from the rotating component 33 for locking or releasing the second connector 32.

[0040] like Figure 1 , 3 As shown, these correspond to the unfolded and flipped states of the tilting and height-adjustable table, respectively. When the tabletop 1 needs to be flipped and stored, the elastic component is pulled outward, pushing the tabletop 1 to rotate along the rotating component 33 to a vertical distance. When the tabletop 1 needs to be unfolded, the vertical tabletop 1 is rotated in the opposite direction to a horizontal position. At this time, the second connecting piece 32 is located in the receiving space of the first connecting piece 31. After releasing the handle, the end of the spring pin component 35 automatically extends into the mounting hole of the second connecting piece 32, thereby fixing the tabletop 1 in a horizontal position. This avoids complex mechanical structures and redundant parts, making the entire flipping system simpler and more efficient, reducing manufacturing and installation costs. The tabletop 1 can be flipped and fixed with a simple pull-out and release action, making operation more convenient, reducing cumbersome steps in the use process, and improving the user experience.

[0041] The flip component 3 allows the desktop 1 to be flipped vertically for storage, saving space. It is especially suitable for environments where office space needs to be saved. The flipped desktop 1 takes up little space and is easy to store when not in use.

[0042] The damping pad 34 is fitted onto the rotating component 33. Through friction buffering, it reduces the vibration and impact during flipping, so that the tabletop 1 will not suddenly fall off due to gravity when flipped to any position. The flipping motion is more stable, avoiding wear of parts caused by rigid collisions and extending service life.

[0043] As a preferred embodiment of the above, refer to Figure 2 , Figure 4 The spring pin assembly 35 includes a base 351, a spring pin 352, and a spring 353;

[0044] The base 351 is disposed on the vertical part 312 and includes a first through hole 351a and a blind hole 351b that are interconnected, and the diameter of the blind hole 351b is larger than the diameter of the first through hole 351a.

[0045] The spring pin 352 includes a first diameter segment 352a in the middle and second diameter segments 352b and third diameter segments 352c on both sides. The diameter of the first diameter segment 352a is larger than the diameters of the second diameter segments 352b and third diameter segments 352c. A spring 353 is sleeved on the second diameter segment 352b. The second diameter segment 352b passes through the blind hole 351b and the first through hole 351a. One end of the spring 353 contacts the bottom of the blind hole 351b, and the other end contacts the side of the first diameter segment 352a. The spring pin 352 moves within the blind hole 351b under force. The spring 353 is used to reset the spring pin 352, so that the third diameter segment 352c is close to the positioning hole of the second connector 32. The reset function of the spring pin 352 can ensure that the desktop 1 is automatically fixed in the required position when unfolded, improving the stability and safety during use.

[0046] In this embodiment, the stepped spring pin 352 design forms a physical limit through the difference in diameter, ensuring that the spring pin 352 moves along a fixed path when the spring 353 is compressed, avoiding deviation or jamming; one end of the spring 353 abuts against the bottom of the blind hole 351b, and the other end contacts the first diameter segment 352a. By utilizing the matching relationship between the diameter of the blind hole 351b and the outer diameter of the spring 353, the spring 353 is prevented from bending laterally, ensuring that the reset direction of the spring pin 352 is always aligned with the positioning hole of the second connector 32, improving the locking success rate; the spring 353 is sleeved on the second diameter segment 352b, and its compression stroke is limited by the first diameter segment 352a and the wall of the blind hole 351b. When the user pulls the spring pin 352, he can feel a clear resistance gradient, and the operation feedback is more intuitive.

[0047] In this embodiment, the end of the third diameter 352c segment is provided with a guide angle 532d. Specifically, the guide angle 532d can be... Figure 6 The arc angle shown can also be a chamfer angle, both of which are within the protection scope of this application. The guide angle 532d forms a guide structure at the end of the spring pin 352. When the third diameter 352c segment approaches the positioning hole, even if there is a slight positional deviation, the guide angle 532d can automatically correct itself by contacting the edge of the hole, avoiding edge jamming and improving the locking success rate.

[0048] The outer surface of the third diameter segment 352c is tapered, and the diameter gradually increases on the side closer to the first diameter segment 352a. On the one hand, the tapered design allows the third diameter segment 352c to be better guided and positioned when it aligns with the positioning hole of the second connector 32, ensuring that the spring pin 352 accurately enters the hole during the locking process, enhancing the accuracy of the alignment and improving the overall locking stability. On the other hand, due to the tapered design, the spring pin 352 has a gradually increasing diameter when entering the positioning hole, allowing it to enter the hole smoothly, reducing friction and resistance during insertion, avoiding operational difficulties or jamming, and improving operational smoothness. Furthermore, when the spring pin 352 is inserted into the positioning hole, the contact area between the tapered surface and the hole wall gradually increases with the insertion depth, generating an adaptive clamping force and forming a radial self-locking effect, increasing stability.

[0049] In this embodiment, the spring pin assembly 35 also includes a handle 354 connected to the second diameter segment 352b. In this embodiment, the second diameter segment 352b is screwed to the handle 354. The handle 354 is teardrop-shaped, which makes it more comfortable and easier for the user to grip when operating the spring pin assembly 35. The teardrop-shaped design is ergonomic, which can reduce finger fatigue and make it easier for the user to operate when flipping the table 1, thus improving the convenience and comfort of use.

[0050] As a preferred embodiment of the above, the base 351 is provided with a protrusion 351c, which is inserted into the through hole of the vertical part 312. A fastener is provided between the base 351 and the vertical part 312. Specifically, the protrusion 351c is designed to disperse the transmission of force, enhance the load-bearing capacity at the connection between the base 351 and the vertical part 312, avoid damage or deformation at the connection due to force concentration, and improve the durability and load-bearing capacity of the overall structure.

[0051] like Figure 5 As shown, a specific embodiment of the rotating component 33 is as follows: The rotating component 33 includes a pull nut 331 and a shear screw 332. The pull nut 331 is disposed in the mounting hole on the side wall of the second connector 32. The shear screw 332 passes through the mounting hole of the vertical part 312 and is screwed to the pull nut 331. Specifically, the precise fit between the shear screw 332 and the pull nut 331 achieves bidirectional locking (radial + axial fixation) of the rotating shaft 45, eliminating the gap of traditional single-point bolt locking, ensuring no shaking during the flipping process, and is especially suitable for high-frequency rotation under the load of the desktop 1. By using the combination of the pull nut 331 and the shear screw 332, the installation process of the rotating component 33 is simpler and easier to adjust. The fit design of the pull nut 331 and the shear screw 332 avoids complex connection processes, making the entire assembly process more efficient and reducing production and maintenance costs.

[0052] Another specific implementation of the rotating component 33 is as follows: the rotating component 33 includes a rotating shaft 45, which passes through the first connector 31 and the two vertical parts 312. Specifically, the rotating shaft 45 directly passes through the first connector 31 and the two vertical parts 312, avoiding unnecessary parts and improving the reliability and stability of the system.

[0053] In this embodiment, reference Figure 3 Foam 313 is provided on the side of the bottom of the first connector 31 away from the rotating component 33. Specifically, the foam 313 can effectively absorb and buffer the impact or vibration that may be generated during the flipping of the desktop 1, reduce the mechanical noise and vibration generated during the flipping, thereby improving the user experience, which is especially important in workplaces that require a quiet environment.

[0054] As a preferred embodiment of the above, the table leg 2 includes an inner tube 21, an outer tube 22, and a locking member 4 disposed at the corner of the outer tube 22;

[0055] The locking component 4 includes a housing 41 disposed on the outer tube 22, a movable block 42 disposed inside the housing 41, and an adjusting component 44 partially disposed inside the housing 41. The movable block 42 has a pressing surface perpendicular to each other on the side near the inner tube 21, and an elastic body 43 is disposed on the pressing surface.

[0056] One end of the adjusting member 44 is a cam structure 441 and the other end is an arc structure 442. A rotating shaft 45 is provided between the cam structure 441 and the housing 41, and the rotating shaft 45 is eccentrically set with the cam structure 441. Rotating the arc structure 442 causes the cam structure 441 to rotate along the rotating shaft 45, thereby driving the movable block 42 to move within the housing 41.

[0057] When using, such as Figure 7 As shown, bending the arc-shaped structure 442 causes the cam structure 441 to rotate. The elastic body 43 on the movable block 42 causes the movable block 42 to retract towards the side of the cam structure 441, contacting the locking limit of the inner tube 21. At this time, the length of the inner tube 21 can be freely pulled. When the inner tube 21 is adjusted to the appropriate position, bending the arc-shaped structure 442 in the opposite direction causes the cam structure 441 to rotate in the opposite direction, squeezing the movable block 42 and driving the elastic body 43 to move closer to the inner tube 21. The elastic body 43 is squeezed, and the inner tube 21 is locked and positioned by the squeezing of the elastic body 43. At this time, the height of the tabletop 1 is fixed. The user only needs to bend the arc-shaped structure 442 to easily adjust the length of the inner tube 21. The operation process is intuitive and simple, greatly improving the convenience of use. Bending the arc-shaped structure 442 in the opposite direction can quickly lock the position of the inner tube 21 without additional tools, reducing the complexity of operation.
