Description

Technical Field

[0001] This utility model relates to the field of writing desk technology, and more specifically, to a multifunctional writing desk that is easy to move. Background Technology

[0002] In existing technologies, there are some obvious problems with the use of a portable multi-functional writing desk. First, the rotation adjustment of the desk surface is unstable. Most existing designs rely on simple support structures or rotating mechanisms for desk rotation, but these structures are prone to loosening or damage after prolonged use, leading to uneven or jammed rotation and severely affecting the adjustment of the desktop angle and the user experience. This instability is particularly pronounced when frequent adjustments to the desktop angle are needed to adapt to different work or study needs, potentially causing operational difficulties and even impacting user comfort and efficiency.

[0003] Secondly, the installation, disassembly, and cleaning of the tabletop are inconvenient. The installation of tabletops in existing designs usually relies on complex locking devices or tools, and disassembly requires a certain amount of time and effort. This design increases the difficulty for users when moving or cleaning, especially when the tabletop needs to be cleaned regularly or the tabletop needs to be replaced. The disassembly process is complicated and time-consuming. In addition, some tabletop designs have small gaps or hard-to-clean areas, which makes it easy for dirt to accumulate during daily cleaning, affecting the hygiene of the tabletop.

When the snap-fit ​​tube 10 is rotated, the inner wall pusher 13 pushes multiple sets of anti-tension spring rods 11 into the slot 12 to form a mechanical lock, which firmly fixes the tabletop 1. When the pusher 13 is rotated in the opposite direction, the anti-tension spring rods 11 move away from the slot 12, realizing quick disassembly. The connecting plate 21 fixes the snap-fit ​​tube 10 on the mounting plate 20 to ensure the stability of the snap-fit ​​structure.

[0037] When the stabilizing mechanism is required to operate, the outer rotating ring 15 drives the longitudinal sliding ring 16 to slide longitudinally on the outer wall of the support tube 8 through a threaded connection. The spring plate 18 on the outer wall of the longitudinal sliding ring 16 is embedded in the ratchet ring 14 at the bottom end of the outer wall of the retaining tube 10 to contact the support, forming a one-way rotation lock. Multiple sets of rotating blocks 17 installed on the end face of the outer rotating ring 15 cooperate with the positioning spring 19 on the outer wall of the retaining tube 10. The positioning spring 19 is embedded into the rotating blocks 17 step by step, so that the outer rotating ring 15 rotates stably on the outer wall of the support tube 8, preventing the locking mechanism from loosening.

[0038] In use, first adjust the angle of the tabletop 1 by rotating the adjustment mechanism, loosen the fixing bolt 6, select the appropriate position of the adjustment hole 7, and reconnect the support plate 5 and the bottom rotating plate 2 through the fixing bolt 6 to achieve the tilt angle adjustment of the tabletop 1. When installing the tabletop 1, pass the locking rod 9 at the bottom of the tabletop 1 through the mounting plate 20 of the mounting bracket 4 and align it with the locking tube 10. Rotate the locking tube 10, and the internal rotary push frame 13 will push multiple sets of anti-tension spring rods 11 to embed into the slot 12, forming a firm mechanical locking connection. The stabilizing mechanism will work automatically. The spring plate 18 and the ratchet ring 14 will form a one-way locking protection.
