Description

Technical Field

[0001] The present application relates to the technical field of lift tables, and in particular to a liftable table. Background Art

[0002] The application scenarios of lifting tables are very wide. They are not only suitable for office places, but also can be used in home office areas, study areas, conference rooms, factories, laboratories and other scenarios. The use of lifting tables can effectively improve working posture and relieve physical problems caused by long-term sitting, such as low back pain, cervical pain and coccyx pain. At the same time, it promotes blood circulation in the body and is beneficial to physical health.

[0003] The existing patent (Announcement No.: CN209750284U) discloses a liftable desk, including a table board, an upper table box fixed to the table board, a lower table box and table legs fixed to the lower table box. A lifting assembly is provided between the upper table box and the lower table box. The lifting assembly includes a rotating shaft rotatably connected to the top of the lower table box, a driving bevel gear is fixed on the rotating shaft, a limit plate is fixed on the top of the lower table box, a screw connected to the bottom of the upper table box is rotatably connected on the limit plate, a driven bevel gear meshing with the driving bevel gear is fixed at one end of the screw, and an end cap for driving the rotating shaft to rotate is rotatably connected to the side wall of the lower table box. When the rotating shaft rotates, the driving bevel gear and the driven bevel gear rotate, and the screw is driven by the driven bevel gear to rotate. Since the screw is threadedly connected to the upper table box, and the two sides of the upper table box are limited between the two side walls of the lower table box, the upper table box moves along the length direction of the screw, thereby realizing the lifting and lowering of the height of the desktop, and the screw lifting method is stepless adjustment, which is highly practical.

[0004] Although the above-mentioned document can adjust the table handle during use, it is impossible to fold the table legs and other structures, which is inconvenient for transportation, and the height of the table body cannot be adjusted when the power is off. At the same time, the connecting wires on common lifting tables are usually connected by tank chains, or directly exposed to the outside, which is inconvenient for installation and disassembly.

[0017] Furthermore, side surfaces of the two support plates that are away from each other are fixedly connected with buckles, and the two buckles are buckled with the storage frame.

[0018] Through the above solution, the mounting buckle can limit the support plate to prevent the support plate from swinging during use.

[0019] Further, the plurality of first springs are all in a reset state, and the plurality of second springs are all in a reset state.

The overall support mechanism can be folded for easy transportation, thereby improving the practicality of the table body. The installation of the plug-in and the plug-in frame can facilitate the installation and removal of the threaded wire, thereby improving the convenience of installing the threaded wire.
