Background

Along with the popularization and application of electric lifting tables, the functional requirements of people on the electric lifting tables are increasing. If one wishes to raise and lower the table top of the table, the table top is divided into a first table top, such as a front table top, and a second table top, such as a rear table top, and the first table top can be made lower, the second table top can be made higher, such as a rear table top, or the first table top can be made equal in height to the second table top, such as a rear table top, according to different needs. To meet this need, in recent years, technicians have gradually devised electric lift tables having a first table plate, such as a front table plate, and a second table plate, such as a rear table plate.

However, the prior art electric lift table having a first table plate and a second table plate still has some disadvantages:

such as: the first table plate is installed on the movable columns of the pair of electric lifting columns at two ends, the second table plate is installed on the fixed columns of the pair of electric lifting columns at two ends through the fixing frame, the first table plate is driven by the movable columns of the electric lifting columns to lift and control the height of the electric lifting columns, but the second table plate can only adopt manual loosening of the locking device, manual upward or downward movement and height control, and re-fastening of the locking device, so that the operation is relatively troublesome, laborious, time-consuming, low in efficiency and poor in accuracy.

Another example is: the first table plate is installed on the movable columns of the pair of electric lifting columns at two ends, the first table plate is driven by the movable columns of the electric lifting columns to lift and control the height of the movable columns, but the second table plate can only be manually loosened, manually moved up or down and controlled in height or spliced into a flat plate, and then the locking device is fastened again.

And the following steps: the first table plate, such as a front table plate, is arranged on the movable columns of the pair of electric lifting columns at two ends, the second table plate is fixed on the first table plate, such as the front table plate, and the second table plate, such as a rear table plate, can only be simultaneously up and down, the relative heights of the first table plate and the second table plate are not adjustable, and various different requirements of users cannot be met.

Also as follows: the first table plate is installed on the first movable columns of the pair of first electric lifting columns like the front table plate, the second table plate is installed on the second movable columns of the other pair of second electric lifting columns like the rear table plate, and when the first table plate and the second table plate lift simultaneously, two sets of motors are required to work simultaneously. When the second table board is independently lifted, the movable column is required to run in the whole process, the power consumption is relatively large, the running cost is relatively high, and the control program is relatively complex; and the respective table boards run simultaneously, the relative shaking amount in the lifting process is large, and the stability is not ideal.
