Easy-to-move demonstration test tube rack for biological experiment teaching

Abstract

The invention provides an easy-to-move demonstration test tube rack for biological experiment teaching. The easy-to-move demonstration test tube rack comprises a lower support plate, a lifting cylinder, an upper support plate, a moving mechanism and a vibrating mechanism, wherein the lower support plate is arranged on the upper surface of a base and is connected with the base through the moving mechanism; the lifting cylinder is mounted on the upper end surface of the lower support plate; the upper support plate is fixed at the upper end of the lifting cylinder; the moving mechanism is arranged on the upper surface of the base; the moving mechanism comprises an opening, an upper rack, a guide sliding block, a moving slot, a guide slot, a collection box, an ejector rod, a lower rack, a sliding chute, a transmission gear and a collection slot; the vibrating mechanism is arranged on the upper surface of the lower support plate and comprises a lower clamp hole, a left support plate, a right support plate, a loading plate, a return spring, a travel switch, a vibrating motor, a spring connecting rod and a bottom plate. Compared with the prior art, the demonstration test tube rack provided by the invention has the following beneficial effects: a function of quick moving of a test tube and a function of automatically and uniformly shaking a solution in the test tube are realized.

Description

technical field [0001] The invention is a convenient mobile demonstration test tube rack for biological experiment teaching, which belongs to the field of teaching equipment. Background technique [0002] The demonstration test tube rack for biological experiment teaching in the prior art is inconvenient to move, and the operation is cumbersome, and the storage effect is not good; the demonstration test tube rack for biological experiment teaching in the prior art cannot realize the function of vibrating and shaking the solution in the test tube, and its functionality is insufficient. So be badly in need of a kind of demonstration test tube frame that is convenient to mobile biological experiment teaching to solve the above-mentioned problem that occurs. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a mobile demonstration test tube rack for biological experiment teaching, so as to solve th...
