Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a lifting table. Background Art

[0002] The existing lifting table includes a table top and two table legs, and the table legs include a fixed sleeve and a movable sleeve. The movable sleeve can move on the fixed sleeve, the movable sleeve is fixed to the table top, and the fixed sleeve is fixedly connected to the base. A driving device is provided in the fixed sleeve of one of the table legs, and the movable sleeve is driven up and down by the driving device to realize the lifting of the lifting table. Such a design requires that the fixed sleeve is large enough to accommodate the driving device, which makes the lifting table very bulky and increases the transportation cost. Secondly, the driving device is designed in the fixed sleeve. If it is damaged, the driving device needs to be removed from the fixed sleeve for maintenance. The removal process is relatively troublesome. If the driving device is simply fixed outside the table leg of the lifting table, it is easy to cause unbalanced force on the two legs, which will lead to unsmooth lifting and shaking during the lifting process.
