Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
The present embodiment provides a desk, as shown in fig. 1 to 5, including a desk foot frame 2, a desktop adjustment mechanism and a desktop lifting driving mechanism. The desktop adjusting mechanism consists of a desktop inclining and fixing mechanism and a desktop rotating and fixing structure, and the desktop inclining and fixing mechanism and the desktop rotating and fixing structure are fixedly connected below the desktop plate 1. The desktop rotating and fixing structure consists of a positioning bolt 4, a fixed disk upright post structure 3 and a rotating movable groove 5, and the rotating movable groove 5 is fixed below the desktop plate 1 and sleeved on the fixed disk upright post structure 3; the positioning bolt 4 is in threaded connection with the rotary movable groove 5, and when the fixing device is fixed, the fixing disc upright post structure 3 is pushed against through spiral rotation, when the fixing disc upright post structure is loosened, the fixing disc upright post structure is in contact with the fixing disc upright post structure 3 through spiral rotation, and the bottom end of the fixing disc upright post structure 3 is fixedly connected with the desktop lifting driving mechanism. Desktop slope fixed establishment comprises arc cardboard 6, locating pin 8 and desktop slope hinge 7, desktop slope hinge 7's downside and desktop board 1 fixed connection, upside and desktop 14 fixed connection, arc cardboard 6 fixed connection is in the below of desktop 14, the one end and the desktop board 1 of locating pin 8 are connected, the other end is used for the activity joint at the hole inslot of arc cardboard 6, adjust ideal inclination with desktop 14, then block with locating pin 8.
