Abstract

The invention provides a table with a lifting device, which is characterized in that the cross section of three-stage telescoped column cavity is rectangle, and the rectangular column cavity is composed of two opposite staple-shaped cavities by way of riveting, wherein the directions of the two opens are opposite, screw fastening or welding butt by a lifting-pulley guide rail in the cavity; a bearing beam is arranged in the lower end of the inner portion of the first-stage column cavity; an upper pulley installation notch and a lower pulley installation notch are respectively arranged at the two walls of one side of the lower half part of the second-stage column cavity and one side of the lower half part of the third-stage column cavity, wherein at least one group of upper pulley installation notches is arranged; the position at the other side of the column cavity and opposite to the pulley-block notch of the third-stage column cavity is provide with a locating pulley, a built-in lever-type elastic wheel carrier and built-in elastic wheels; a pulley cavity is respectively fixed at the outer sides of the notches of the second-stage column cavity, and the cavity body of the pulley cavity and the corresponding position of the notch on the column cavity are also provided with pulley installation notches which are consistent with the notch on the column cavity; and the position at the other side of the column cavity opposite to the pulley-block notch of the column cavity is provided with a locating pulley frame and pulleys as well as an external lever-type elastic wheel carrier and external elastic wheels.

Description

technical field [0001] The invention relates to the technical field of office furniture, in particular to a table with a lifting device. Background technique [0002] Desks, especially office workbenches, are tools needed for people to work and study. The size, height, and angle of the desktop all have a certain impact on people's work, study, and health. At present, whether it is a desk, a desk, or a workbench used by professional technicians to engage in computer 3D design, its height is fixed, and users of different occupations, ages, and heights are in a state of passive adaptation. With the advancement of science and technology, qualitative changes have taken place in people's work, study, and lifestyle, which to a certain extent makes the existing desks unable to adapt and meet people's all-round needs for different "desk" functions. Now, professional and technical personnel, especially those who use computers for a long time to work, passively maintain a static stat...
