Movable teaching experiment table

Abstract

The invention discloses a movable teaching experiment table. The structural principle of telescopic moving wheels is adopted, the table comprises a bracket, a table body arranged on the upper surfaceof the bracket and a plurality of supporting leg assemblies connected with the lower surface of the bracket, and the supporting leg assemblies comprise supporting legs, supporting columns, lifting mechanisms and the moving wheels; the lifting mechanisms comprise bearing plates, core shafts, driven wheels, rotary shafts, drive shafts, handles and sliding blocks, by rotating the handles forward andreversely, the drive wheels drive the driven wheels to rotate, and the driven wheels drive the core shafts to rotate, so that the core shafts drive the sliding blocks to slide up and down along rectangular cavities to achieve that the moving wheels extend outward and retract inward relative to the rectangular cavities of the supporting legs; when the experiment table needs to be moved, the movingwheels can extend outward, if the experiment table is placed for a long time, the moving wheels can be retracted to utilize the bottoms of the supporting legs to make contact with the ground, therefore the moving convenience of the experiment table is improved, the supported mechanical strength and placing stability of the experiment table can be ensured, the operation is simple, and the using isconvenient.

Description

technical field [0001] The invention relates to the technical field of teaching experiment supplies, in particular to a movable teaching experiment table. Background technique [0002] The experimental table is an indispensable product in the teaching experiment process. When students are performing experimental activities or operations, it can be used to provide equipment and tools in the experiment to place the table; the so-called theory and practice are inseparable. Colleagues, experiments are the only way to verify the theory; at the same time, according to different subjects of experiments, they can be divided into physical experiment tables, chemical experiment tables or biological experiment tables. However, many experiments have higher requirements on the experimental table, for example, the levelness of the experimental table can be guaranteed. At present, more practical experimental tables include legs, brackets, spirit levels, table bodies and other structural c...

AI Technical Summary

Problems solved by technology

[0004] But the mobile adjustable leveling experimental table of above-mentioned technical scheme exists: roller is connected and fixed on the end of leg by rivet, although can be convenient to the movement of experimental table, but in the use process of experimental table, roller must touch the ground for a long time, and roller and The ground is in line contact. Obviously, line contact is not conducive to forming a reliable mechanical support for the tabletop. At the same time, the rollers are easy to slide with the ground. Even if it is locked with a brake device, the table body will be unstable due to the push and pull of external force. However, its practicability is not high, and it cannot meet the needs of teaching experiments.
