Description

Technical Field

[0001] This utility model belongs to the field of height-adjustable desk technology, specifically relating to a rotatable height-adjustable desk. Background Technology

[0002] Human evolution progressed from quadrupedal to bipedalism. Research into the history of furniture development worldwide revealed that after adopting bipedalism, humans discovered that sitting reduced fatigue during daily activities, leading to the invention of seating. This seated work style was passed down, but as people spent increasingly more time sitting at work, they gradually realized that prolonged sitting was detrimental to work efficiency. People began experimenting with alternating seated and standing work, gradually leading to the development of height-adjustable desks. Using height-adjustable desks for standing work has become a popular and healthy work style.

[0003] Existing Chinese patent CN202022713824.7 discloses a height-adjustable table adjustment device and a height-adjustable table. It includes an adjustment mechanism comprising a drive motor and an adjustment section driven by the drive motor. The adjustment section includes a nut, a screw, and a drive structure. A support base is mounted on the height-adjustable table. The screw is rotatably connected to the support base, and the screw is fixedly connected to a hexagonal rod between the screw and the table legs. A nut, horizontally positioned within the support base, is threaded onto the screw. The drive structure is driven by the drive motor and rotates the screw. A limit switch is installed within the support base; the nut moves along the screw and stops when it touches the limit switch. A height-adjustable table with a height-adjustable table adjustment device fixed on it is also described.

[0004] The existing technical solutions mentioned above have the following drawbacks: Although the screw can be driven to rotate by the drive motor through the drive structure, and the nut slides along the screw as it rotates, the lifting table can be stopped at different heights by touching the limit switches at different positions, the table can only be raised and lowered, and cannot be folded to allow the user to tilt it for use. Utility Model Content

[0005] The purpose of this utility model is to provide a rotatable height-adjustable table to solve the technical problem that the table can only be raised and lowered, but cannot be folded to allow users to tilt it for convenient use. The goal is to enable the table to be freely flipped, thus providing convenience for users.

[0006] To solve the above-mentioned technical problems, this utility model provides a rotatable and height-adjustable table, comprising:

[0007] A base, a lifting rod on the base, and a beam frame above the lifting rod, wherein a first table and a second table are provided on the beam frame;

[0008] A rotating mechanism is provided between the beam frame and the first tabletop. The rotating mechanism includes a rotating shaft coaxially arranged with the locking beam frame and a control switch provided on the first tabletop. A first annular rack is provided at the end of the rotating shaft facing the beam frame, and a second annular rack is provided at the end of the beam frame facing the rotating shaft. The first annular rack meshes with the second annular rack. A spring is provided between the control switch and the rotating shaft to abut the rotating shaft against the beam frame. The control switch pulls the spring away from the end of the rotating shaft.

[0009] Furthermore, a first fixing ring is provided on the first tabletop, and the first fixing ring is sleeved at the connection between the beam frame and the rotating shaft.

[0010] Furthermore, a first reinforcing rib is provided between the first fixing ring and the first tabletop, and the first reinforcing rib is fixed to the first tabletop by bolts.

[0011] Furthermore, a second fixing ring is provided between the beam frame and the second tabletop, and the second fixing ring is fixed at the connection between the beam frame and the rotating shaft.

[0012] Furthermore, a second reinforcing rib is provided between the second fixing ring and the second tabletop, and the second reinforcing rib is fixed to the second tabletop by bolts.

[0013] Furthermore, the bottom of the base is provided with an anti-slip pad.

[0014] The beneficial effects of this utility model are:

[0015] 1. When the user pulls the control switch backward, the spring is retracted, the rotating shaft is separated from the beam frame, and then the first table is rotated to adjust the angle of the first table. After adjustment, the user releases the spring, and the spring pushes the rotating shaft to the beam frame through its own tension. At the same time, the first ring rack meshes with the second ring rack, thereby fixing the tilted first table.

[0016] 2. The overall stability of the height-adjustable table is improved by using the first and second fixing rings.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Example:

[0034] like Figures 1 to 4As shown, a rotatable height-adjustable table includes: a base 1, a lifting rod 2 disposed on the base 1, and a beam frame 3 disposed above the lifting rod 2. A first tabletop 4 and a second tabletop 5 are disposed on the beam frame 3. In this embodiment, an anti-slip pad 11 is provided at the bottom of the base 1.

[0035] A rotating mechanism 6 is provided between the beam frame 3 and the first table 4. The rotating mechanism 6 includes a rotating shaft 61 coaxially arranged with the locking beam frame 3 and a control switch 62 provided on the first table 4. A first annular rack 63 is provided at the end of the rotating shaft 61 facing the beam frame 3, and a second annular rack 64 is provided at the end of the beam frame 3 facing the rotating shaft 61. The first annular rack 63 meshes with the second annular rack 64. A spring is provided between the control switch 62 and the rotating shaft 61 to abut the rotating shaft 61 against the beam frame 3. The control switch 62 pulls the spring away from the end of the rotating shaft 61. The user pulls the control switch 62 outward, causing the spring to pull away from the rotating shaft 61, disengaging the first annular rack 63 from the second annular rack 64. The user then tilts the first tabletop 4, causing it to rotate around the rotating shaft 61 to adjust its angle. After adjustment, the user releases the spring, which, through its own tension, pushes the rotating shaft 61 toward the frame beam. Simultaneously, the first annular rack 63 engages with the second annular rack 64, thus fixing the tilted first tabletop 4 in place.

[0036] like Figures 1 to 4 As shown, a first fixing ring 7 is provided on the first table board 4. The first fixing ring 7 is sleeved at the connection between the beam frame 3 and the rotating shaft 61. The first fixing ring 7 can improve the docking stability between the beam frame 3 and the rotating shaft 61 and improve the accuracy of the first annular rack 63 meshing with the second annular rack 64.

[0037] like Figures 1 to 4 As shown, a first reinforcing rib 71 is provided between the first fixing ring 7 and the first tabletop 4. The first reinforcing rib 71 is fixed to the first tabletop 4 by bolts, thereby improving the firmness of the first fixing ring 7. Similarly, a second fixing ring 8 is provided between the beam frame 3 and the second tabletop 5. The second fixing ring 8 is fixed at the connection between the beam frame 3 and the rotating shaft 61, thereby improving the connection stability between the beam frame 3 and the second tabletop 5. At the same time, a second reinforcing rib 81 is provided between the second fixing ring 8 and the second tabletop 5. The second reinforcing rib 81 is fixed to the second tabletop 5 by bolts, thereby improving the stability of the second fixing ring 8 on the second tabletop 5.

[0038] In summary: by pulling the control switch 62 backward, the spring is retracted, the rotating shaft 61 is disengaged from the beam 3, and then the first tabletop 4 is rotated to adjust its angle. After adjustment, the user releases the spring, which, through its own tension, pushes the rotating shaft 61 back towards the beam. Simultaneously, the first annular rack 63 engages with the second annular rack 64, thereby fixing the tilted first tabletop 4. The first fixing ring 7 and the second fixing ring 8 enhance the overall stability of the height-adjustable table.
