Abstract

The invention provides a transmission assembly and a lifting vertical column. The transmission assembly comprises a first screw rod, a second screw rod, a third screw rod, a driving device, a first nut which is in transmission fit with the first screw rod, a first sleeve fixedly connected with the first nut, a second nut which is in transmission fit with the second screw rod, a second sleeve fixedly connected with the second nut, a third nut which is in transmission fit with the third screw rod, and a third sleeve fixedly connected with the third nut; the first nut, the second nut and the third nut are fixedly arranged in the circumferential direction, the second screw rod and the third screw rod are hollow, the first screw rod and the second screw rod can rotate synchronously and expand and contract relatively in the axial direction, and the second screw rod and the third screw rod can rotate synchronously and expand and contract relatively in the axial direction; and the four-sectiontransmission assembly achieves driving through rotation of the screw rods, the sleeves are driven by the nuts to achieve expanding and contracting, and thus, transmission of the transmission assemblyis stable and reliable.

Description

technical field [0001] The invention relates to the technical field of a transmission assembly, in particular to a transmission assembly and a lifting column. Background technique [0002] Lifting products such as lifting tables have been widely used in daily life due to the advantages of adjustable height and convenient transportation. With the development of lifting products, the demand for lifting distance is getting higher and higher. At present, the lifting columns on the lifting tables on the market are generally two-section lifting columns or three-section lifting columns. The lifting distance is limited, and the height of the lifting column with a larger lifting distance is higher, which makes the product larger and is not conducive to transportation. and storage. Contents of the invention [0003] The object of the present invention is to provide a four-section transmission assembly and a lifting column with stable transmission. [0004] In order to achieve the ...
