Abstract: A tabletop assembly, a lifting frame assembly and a height adjustable table are disclosed. The assembling operation of the height adjustable table is simplified by using a supporting part rotatably connected to a table board support and a first terminal block and a second terminal block which are arranged in pairs. During transportation, the height adjustable table may be disassembled into a tabletop assembly and a lifting frame assembly to be packaged and transported, respectively, thus reducing the size of the package. Meanwhile, the lifting frame assembly may be folded, the second terminal block on the lifting frame assembly in a folded state forms an approximate fan-shaped region with the table board support, so that the second terminal block may be protected during transportation. After receiving the goods, the consumer may assemble the tabletop assembly and the lifting frame assembly through a simple process.

Abstract: Provided is a lift desk. The lift desk includes a support base, a first desk board, a second desk board and an adjustment support assembly, where the first desk board is connected to the support base by a lift mechanism; the second desk board is connected to the first desk board and positioned between the support base and the first desk board, and the second desk board is provided with a groove at a side of the second desk board facing towards the first desk board. The adjustment support assembly includes a support block. The support block is slidably disposed in the groove and configured to cooperate with the second desk board to support a supported object.

Abstract: A liftable table leg includes a bushing, a second fixing piece, a lift assembly, a fixing base and a drive assembly. A first fixing piece is sleeved on a first end of the bushing. The second fixing piece includes a fixing flange and an accommodation groove. The first end is fixed to a bottom end of the accommodation groove through the first fixing piece. A nut of the lift assembly is fixedly disposed at a second end of the bushing. A lead screw of the lift assembly is rotatably disposed in the bushing and threaded into the nut. The second fixing piece is fixedly disposed at the fixing base through the fixing flange. The drive assembly includes a fixing frame. An end of the lead screw is rotatably connected to the fixing frame, and the drive assembly is capable of driving the lead screw to rotate.
