Office table with fluid damping structure

Abstract

The invention discloses an office table with a fluid damping structure, which comprises a lying plate and a fluid damping unit, one end of the lying plate is rotatably connected to a table top plate around a pivot, the fluid damping unit is operably connected with the lying plate and the table top plate, and the fluid damping unit is configured to not apply damping force to the lying plate when the lying plate rotates around the pivot in a first rotating direction. And when rotating around the pivot in a second rotation direction opposite to the first rotation direction, the damping force is applied to the lying plate. By arranging the lying plate which can partially rotate to the position above the table top plate, office staff can conveniently lie down to sleep, the sleeping posture is improved, and the comfort degree is improved. Meanwhile, the fluid damping unit is arranged, so that when the user opens the lying plate in the first rotating direction, damping is not achieved, and when the user folds the lying plate in the second rotating direction, damping is achieved, and the situation that the lying plate rapidly falls off in the process of rotating in the second rotating direction, the user is knocked or collided with other objects is prevented.
