Combined desk and chair for physical experiment

Abstract

The invention discloses a combined table and chair for a physical experiment. The combined table and chair comprises an experiment table, a seat, a supporting box and vibration-damping column assemblies, wherein the left part of the lower end of the experiment table is provided with a first motor; the left part of the lower end of the first motor is connected with a first screw; the lower end of the first screw is provided with a first fixed pipe; a first threaded hole corresponding to the first screw is arranged in the first fixed pipe; and the lower end of the first fixed pipe is connected with the central part of the upper end of a horizontal pipe. According to the invention, an L-shaped telescopic rod can be pushed or pulled to control expansion and contraction of the seat, and the space of a laboratory is saved, so more experiment tables and chairs can be placed in the laboratory, and convenient cleaning is realized; meanwhile, the first motor can drive the first screw to rotate,and the rotating first screw controls the horizontal pipe to ascend and descend through the first fixed pipe under cooperation of a vertical rod and the telescopic rod, so a table and a chair are controlled to ascend and descend, and the heights of the table and the chair can be conveniently adjusted according to the height of a user; thus, the combined table and chair for the physical experimental is improved in practicability.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a combined physics experiment table and chair. Background technique [0002] The physical experiment table is an experimental tool commonly used in the process of physical experiments. The physical experiment table provides students with the experimental platform needed for physical experiments. With the continuous development of science and technology, students have higher requirements for the physical experiment table. usage requirements. [0003] At present, the existing physical experiment table occupies a large area, basically every time you walk around, you can only pass through the space between the two experimental tables, and a chair should be placed between the two experimental tables to facilitate people's use, but when the chair is moved It is inconvenient, and the space reserved by the two experimental tables is limited, so every time someone wants to pas...

Problems solved by technology

[0003] At present, the existing physical experiment table occupies a large area, basically every time you walk around, you can only pass through the space between the two experimental tables, and a chair should be placed between the two experimental tables to facilitate people's use, but when the chair is moved It is inconvenient, and the space reserved by the two experimental tables is limited, so every time someone wants to pass, the sitting person has to stand up and move the chair, leaving space for people to pass, which is very inconvenient, and it will cause more trouble when moving. Loud noise. In addition, when cleaning the floor, you have to move the chair at least twice each time, which increases labor intensity and takes longer to clean.
