Description

A new type of hidden linkage desk

technical field

The present invention relates to a desk, more particularly, to a novel hidden linkage desk.

Background technique

At present, computers have played a very important role in people's lives. Because the height of the computer cannot be adjusted behind the desk, when people sit and use it, it will lead to sub-health of the user's wrist, arm, shoulder circumference, lumbar spine and other parts, as well as fatigue or injury.

In order to solve the above-mentioned problems, there is a need for a desk that can be adjusted in height and even enables the operator to work standing up. At present, the improvement of the desk in the market, or the area used to place the computer in the desk is designed to be raised and lowered. After searching, there have been technical solutions to improve the above shortcomings. For example, China Patent No. 2015200423133, the date of authorization announcement is 2015 On July 29, the name of the invention and creation is: elevating computer desk, the application involves a elevating computer desk, including a lifting device, the lifting device is arranged below the back end of the desktop, and the lifting device includes a lifting base, a lifting hydraulic pressure Oil cylinder and lifting bracket, the lifting rod under the lifting bracket is fixedly connected with the hydraulic rod of the lifting hydraulic cylinder through the opening of the lifting base, the top of the lifting bracket is fixed with a display support plate parallel to the desktop, and the desktop corresponds to the display support plate The position is hollowed out, so that the monitor tray can be raised and lowered from the desktop. The application can adjust the height of the part where the computer monitor is placed according to the user's needs, so that the user can avoid working with their heads lowered, so that the health of the body will not be affected by working with the head down and sitting for a long time, but the application In the case, the lifting device only considers the adjustment when sitting and working, ignoring the impact on the user's health caused by sitting and working for a long time;

Either the desk itself is designed to be liftable. After searching, technical solutions for improving the above shortcomings have been disclosed, such as China Patent No. ZL2017109549855, the authorization announcement date is January 3, 2020, and the name of the invention is: a A liftable desk, the application relates to a liftable desk, including a desk board, a monitor bracket, a locking mechanism and a cross-lifting mechanism, the display bracket is slidably connected to the front side of the desk board, and the locking mechanism is connected to a The cross lift mechanism at the bottom of the table board is connected, and the table board can be lifted and stably fixed at different heights by adjusting the locking mechanism. In this application, the lifting and lowering of the table is controlled by a cross-lifting mechanism. Although the cross-lifting mechanism has a large lifting range and can be used for standing and sitting work at the same time, it is found in actual use that when it rises to a certain height, it is easy to be "top-heavy". Being knocked down, the stability of placement is poor;

Or put a computer desk that can be raised and lowered on the desk. Although it can meet the purpose of standing and sitting, but after all, standing work time occupies a small proportion of the entire office time, so the computer desk is usually stored. is a problem.
