Description
Technical Field
The invention relates to an office table, in particular to a novel hidden linkage office table.
Background
At present, computers have played a very important role in people's lives. Because the height of the computer can not be adjusted after the computer is placed on an office table, the sub-health of the wrist, the arm, the shoulder, the lumbar and the like of a user can be caused when people sit for use, and the fatigue or the injury can also be caused.
In order to solve the above problems, there is a need for a desk that is adjustable in height and even allows an operator to work while standing. The improvement of the office table in the current market, namely the region for placing a computer in the office table is designed to be lifted, and through retrieval, a technical scheme for improving the defects is disclosed, for example, a Chinese patent number 2015200423133, which is published as 2015, 7 and 29, and the invention creates a name: over-and-under type computer desk, this application relates to an over-and-under type computer desk, including elevating gear, elevating gear sets up in desktop rear end below, and elevating gear includes lift base, lifting hydraulic cylinder and lifting bracket, and the lifter of lifting bracket below passes lift base opening and lifting hydraulic cylinder's hydraulic stem fixed connection, and the lifting bracket top is fixed with the display layer board parallel with the desktop, and the desktop is the fretwork form with the corresponding position of display layer board, makes the display layer board go up and down from the desktop. The height of the part for placing the computer display can be adjusted according to the needs of a user, so that the user can avoid lowering the head to work, the health condition of the body cannot be influenced by lowering the head to work and sitting for a long time, but the lifting device only considers the adjustment when the user sits for office, and the influence of the long-time sitting for office on the health of the user is ignored;
Or the office table is designed to be liftable, and through retrieval, an improved technical scheme aiming at the defects is disclosed, for example, the Chinese patent number ZL2017109549855 is published in the publication date of 2020, 1 month and 3 days, and the invention creates a name: the utility model provides a liftable desk, this application relates to a liftable desk, and including table, display bracket, locking mechanism and alternately elevating system, display bracket sliding connection is in the front side of table, and locking mechanism is connected with the alternately elevating system who locates the table bottom, realizes through adjusting locking mechanism that the table goes up and down and stably be fixed in not co-altitude. In the application, the lifting of the table plate is controlled by the cross lifting mechanism, and although the lifting range of the cross lifting mechanism is large, the cross lifting mechanism can be simultaneously used for standing and sitting for work, but in actual use, the table plate is easy to be knocked down due to 'heavy head and light feet' after being lifted to a certain height, and the placement stability is poor;
or place liftable ground desk on the desk, like this although can satisfy can stand the official working and also can sit the purpose of official working, the time of work of standing after all occupies the proportion in whole office time little, consequently the desk accomodates at ordinary times is a problem.
