This desk integrates the functions of folding and unfolding the main tabletop, height adjustment, and extending and locking the secondary tabletop. It realizes the rapid and stable conversion between folding, standing, and extended work area modes, which significantly improves the product's spatial adaptability, ease of operation, and structural stability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A multi-functional folding office desk includes a base, a main tabletop, and a secondary tabletop. The base has symmetrical folding components on both sides of its upper end, and the main table is fixedly connected to the upper ends of the two folding components. The folding assembly includes a sliding frame, a sliding rod, a sliding block, and a folding rod. The sliding frame is fixed to the upper end of the base and the lower end of the main table. The sliding rod is set horizontally inside the sliding frame. The sliding block is sleeved on the sliding rod and slides with the sliding rod. The lower and upper ends of the folding rod are both hinged to the sliding block. The auxiliary tabletops are provided in two parts and are respectively connected to both sides of the main tabletop via hinges; The sub-table is equipped with a locking mechanism, which includes a guide rod fixed inside it, a pull rod slidably connected to the outside of the guide rod, limiting plates fixedly connected to both ends of the pull rod, and a compression spring sleeved on the outside of the guide rod as an elastic element. One end of the compression spring abuts against the inner wall of the sub-table and the other end abuts against the middle of the pull rod, and is used to drive the two limiting plates to extend or retract synchronously, so as to lock or unlock with the limiting grooves corresponding to both sides of the main table. The base is also equipped with a lifting and adjusting mechanism for adjusting the height of the main table. The base has vertical plates that slide vertically on both sides of its interior, and a horizontal plate is fixedly connected between the two vertical plates. The base is also equipped with a lifting adjustment mechanism 2 for driving the two vertical plates to lift synchronously. Through the above technical solution, the desk integrates the functions of folding and unfolding the main tabletop, height adjustment, and extending and locking the secondary tabletop, realizing a rapid and stable conversion between modes such as folding, standing, and extending the work area, which significantly improves the product's spatial adaptability, ease of operation, and structural stability.

During unfolding, pushing the locking mechanism's pull rod 18 inward causes the limiting plate 19 to retract. Once the secondary tabletop 3 is fully unfolded and aligned with the main tabletop 2, it is released. The compression spring 17 then drives the limiting plate 19 to pop out and engage with the limiting groove 20 of the main tabletop 2, completing the locking. Next, the height of the main tabletop 2 is adjusted as needed. First, the first throttle 8 is turned, which drives the folding assembly 4 to unfold through the cooperation of the bidirectional threaded rod 6 and the threaded cylinder 7, raising the main tabletop 2 to the desired height. After adjustment, the limiting assembly 9 automatically locks to ensure stability. Then, the second throttle 14 is turned, which fine-tunes the upright plate 11 through the unidirectional threaded rod 13 to achieve the most comfortable usage height. After fine-tuning, the limiting assembly 15 locks to prevent movement. Finally, the brakes on the casters 5 are applied to secure the entire desk, and it is ready for use. When finished using the desk and ready for storage, first, push the pull rod 18 inward to disengage the limiting plate 19 from the limiting groove 20, unlock and lower the secondary tabletop 3. The magnetic components will attract and fix it to the side wall of the base 1. Then, turn the second handle 14 in the opposite direction to retract and fine-tune the height, and then turn the first handle 8 in the opposite direction to drive the folding assembly 4 to fold up, allowing the main tabletop 2 to smoothly descend to its lowest position. Finally, release the brakes on the casters 5 to easily move the desk for storage or transport. The operation is intuitive, greatly improving user convenience.
