Description
Technical field
The present invention relates to a kind of synchronous lifting device and desks.
Background technology
Desk is commonly in as a kind of daily necessities in life, work and Learning in School, general desk usually by
Desktop is formed by fixedly connecting with table leg, and the length of table leg is also fixed, so that the height of entire desktop is to fix not
It is adjustable.And with the difference of application environment and the application demand of different crowd, to the high diversity of desk, automatic
Degree, the requirement of level of comfort are also higher and higher.
It there is now the table leg support using gas spring as desk and make face, control gas spring is installed in the lower surface of desktop

Rope connector is hinged on connection component) connection, the other end of the tieback connection and the switch of gas spring support, when needing table
When son rises or drops, power is made tieback connection rotate by user by controlling control assembly by drag-line, to make gas spring
Switch open, rise or drop according to the intention of user to gas spring.
Since the table leg at desk both ends is supported by gas spring, when manipulating desk lifting, need to keep gas spring same
Step operation, is otherwise raised and lowered on one side, and another side is tilted also in not dynamic state so as to cause desktop, such as when
When needing that desktop is made to decline, the lower pressure that manipulator receives one end application of desk is big, and the lower pressure that the other end applies is small, this
Kind situation is to be easiest to cause desktop inclined.
Invention content
The purpose of the present invention is to provide a kind of synchronous lifting device and desk, the present invention can make at least the two of lifting gear
End synchronizes lifting in lifting.
