A test bench with convenient platform lifting

Abstract

The invention provides a test bed with a bed plate convenient to lift. The test bed comprises a base, a height adjusting mechanism, the bed plate and a positioning rod; the height adjusting mechanism comprises a screw rod, a lifting cylinder, a rotating disc, a limiting rack and a limiting frame; an object storage tank is arranged on the base; the screw rod is mounted in the object storage tank; internal threads are formed in the lifting cylinder; the lifting cylinder is connected with the screw rod through the internal threads; the rotating disc is rotationally mounted on the lifting rack; the upper end of the lifting cylinder is connected with the rotating disc; the limiting frame can be mounted on the base in a manner of vertical movement, and the upper end of the limiting frame is connected with the limiting rack; the bed plate is rotationally mounted at the upper part of the limiting rack; a first internal thread through hole is formed in the lower part of the bed plate; external threads are formed in the positioning rod; the positioning rod is mounted on the bed plate through the external threads and the first internal thread through hole in a matching manner; the positioning rod is movably propped against the limiting frame. The test bed provided by the invention has the benefits that the structure is simple, and the bed plate is convenient and quick to lift and is convenient to rotate.

Description

technical field [0001] The invention relates to experimental auxiliary equipment, in particular to a test bench with a convenient lifting platform. Background technique [0002] Experimental benches are widely used in laboratories. With the development of laboratory equipment, the requirements for experimental benches are getting higher and higher. Manufacturers of experimental benches will use fixed-height models for production profits and production efficiency. However, due to the different heights of different users, their usage habits are not the same, the customers of the same batch of test benches may not be satisfied with the height model of the test bench, which will affect the user's satisfaction. Therefore, there is an urgent need for a test bench that is convenient for height adjustment on the market. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a test bench with a conve...
