Digital display constant-temperature water bath box

Abstract

The invention discloses a digital display constant-temperature water bath tank. The digital display constant-temperature water bath tank comprises a containing assembly, a bearing assembly and a heating assembly. The containing assembly comprises a box body and a box cover. A sliding groove is formed in the inner wall of the box body. The box cover is hinged to the side part of the box cover, thebearing assembly comprises a frame, a transverse rod and a pressing piece, a sliding rod is installed on the lower portion of the frame and inserted into the sliding groove in a sliding mode, the transverse rod is installed on the inner side of the frame, the pressing piece is installed on the side portion of the transverse rod, the heating assembly comprises a heat insulation connecting piece andan electric heating rod, and the heat insulation connecting piece is installed between the inner wall of the box body and the heat insulation connecting piece. According to the scheme, the test tubesare pressed between the pressing pieces through the pressing pieces, fixation of the test tubes is effectively achieved, fixation of the test tubes with different diameters can be met, the test tubesare supported through the transverse rods, water in a water bath can pass through gaps between the transverse rods, and then obstruction to heat diffusion and exchange is reduced.

Description

technical field [0001] The invention relates to the technical field of water bath boxes, in particular to a digital display constant temperature water bath box. Background technique [0002] The digital display water bath box is widely used for drying, concentrating, distilling, impregnating chemical reagents, impregnating medicines and biological products, and can also be used for water bath constant temperature heating and other temperature tests. An essential tool for education and scientific research in biochemical laboratories and analysis rooms. [0003] For the water bath box used in biochemical experiments, the test tube is generally inserted into the test tube holder of the water bath box (the test tube slot is set in the middle of the test tube holder), so that the test tube is suspended in the air and forms a certain distance from the heating device. However, in the water bath box, It is easy to cause the test tube to float due to the buoyancy of the water, which...

[0003] For the water bath box used in biochemical experiments, the test tube is generally inserted into the test tube holder of the water bath box (the test tube slot is set in the middle of the test tube holder), so that the test tube is suspended in the air and forms a certain distance from the heating device. However, in the water bath box, It is easy to cause the test tube to float due to the buoyancy of the water, which will affect the contact between the test tube and water and the effect of the water bath. When the test tube is fixed on the test tube, the test tube will block the test tube slot, which will hinder the diffusion and exchange of heat. Affects the effect of the water bath
