Embodiment 1

[0053] As shown in Figure 1A. A table with a lifting device includes a desktop 1, a desktop angle adjusting device 2, a lifting device 3, a column cavity connecting plate 4, a column base 5, and a column base connecting plate 6.

[0054] For the first embodiment, it also includes a braking device 328 (which will be described below). A schematic diagram of the desk according to the first embodiment is shown in FIG. 1B, which shows the brake handle 8 of the brake device 328 and the angle adjustment knob 7 of the desk angle adjustment device 2 which will be described below.

[0055] The specific structure of the desktop angle adjusting device 2 is shown in FIG. 2. It includes a hinged fulcrum 21 of a fixed desktop arranged on one side of the desktop, an angle adjusting knob 7 connected with the hinged fulcrum 21 of the fixed desktop, and an angle adjusting knob 7. The transmission screw 24 connected to the handle 7, the transmission screw fixing fulcrum 23 that fixes the transmission...

Embodiment 2

[0066] The main difference between this embodiment and Embodiment 1 lies in the transmission device. The transmission device in this embodiment will be described below with reference to the accompanying drawings.

[0067] See Figure 5. The lifting device in this embodiment includes a lifting mechanism and a transmission mechanism. The lifting mechanism includes a column cavity of a three-stage stack, and the transmission mechanism includes a telescopic three-stage stack corresponding to the column cavity of the three-stage stack. For the threaded push rod, the implementation of the lifting mechanism is the same as that of the first embodiment, and those skilled in the art can refer to the above-mentioned embodiment 1 to implement the corresponding part of the second embodiment, which will not be repeated here. Only the transmission mechanism in the lifting device will be described in detail below.

[0068] The transmission mechanism in the lifting device of this embodiment include...

Embodiment 3

[0075] The difference between this embodiment and Embodiment 1 and Embodiment 2 mainly lies in the transmission mechanism in the lifting device. The implementation of the transmission mechanism of the lifting device in this embodiment will be described below with reference to the accompanying drawings.

[0076] The transmission mechanism of the lifting device in this embodiment includes a traction steel cable 3110, a steel cable lifting bearing pulley 3114, 3214, and a third steel cable fixed end 3312. In this embodiment, the lifting mechanism is a non-closed column cavity with an opening on one side of the three-stage stack.

[0077] See Figure 7. In this embodiment, a traction steel cable 3110 is provided in the lifting device, and a steel cable fixed end 3212 is fixedly installed at the lower end of the inner wall of the third-stage column cavity 33 to move up and down and slide with the third-stage column cavity 33 at the same time; The opening side of the upper end is provide...

Abstract

The invention relates to a table equipped with lifting device, comprising table top, angle moderating device, lifting device, column-cavity binding board, column base and column base binding board. The lifting device comprises lifting structure and driving structure; lifting structure includes the first, second and third grade overlapped column cavity, each of them are connected through pulley and slide rail, the second grade column cavity is located inside the first grade column cavity and slides up and down based on the first grade column cavity, the third column cavity is installed in the second grade column and slides up and down based on the second grade column cavity; pulley suitable to the first grade column cavity and on one side of the second grade column cavity is located between the first and second grade column cavity, and elastic wheel and spring arm on the other side of the second grade column cavity are located between the first and second grade column cavity; pulley suitable to the second grade column cavity and on one side of the third grade column cavity is located between the second and second grade column cavity, and elastic wheel and spring arm on the other side of the third grade column cavity are located between the second and third grade column cavity; the second grade and third grade column cavity can slide up and down adjustably. The invention is great importance for workers' health and work efficiency increase.

Description

Technical field [0001] The invention relates to the technical field of office furniture, in particular to a table with a lifting device, table top height and table top angle adjustable. Background technique [0002] A desk, especially an office workbench here, is a tool for people to work and study. The size, height, and angle of the table will all have a certain impact on people's work, study, and physical health. At present, whether it is an executive desk, a desk or a workbench used by professional and technical personnel to engage in computer 3D design, the height is fixed, and users of different occupations, ages, and heights are in a state of passive adaptation. With the advancement of technology, people's work, study, and lifestyle have undergone qualitative changes. To a certain extent, the existing desks can no longer adapt to and meet people's all-round needs for different "desk" functions. Nowadays, professional and technical personnel, especially those who use compu...
