Abstract
A lifting desk support having rapid mounting structures and a lifting desk are provided. The lifting desk support includes a longitudinal beam and a cross beam assembly. The lifting desk support further includes a set of rapid mounting structures, which comprises a boss having a slope arranged on the longitudinal beam and a notch provided on the cross beam assembly. A locking block of the boss is embedded into the cross beam assembly through a first groove section of the notch, and a force along an axial direction of a cross beam of the cross beam assembly is applied to the longitudinal beam, such that the locking block enters a second groove section of the notch, and the locking and the assembly between the longitudinal beam and the cross beam assembly are achieved in a rapid and efficient manner with cost saved.
