A kind of flask heating support

Abstract

The invention discloses a heating bracket for a flask. The heating bracket comprises a base, wherein a supporting rod is arranged on a lateral part of the base; the supporting rod and the upper surface of the base are vertical to each other; a bearing tray is arranged on the supporting rod; a bracket tray is arranged on the bearing tray; a cylindrical cavity is formed in the bracket tray; a cushion block I, a cushion block II, a cushion block III and a cushion block IV are arranged in the cavity; the cushion block I, the cushion block II, the cushion block III and the cushion block IV are all arranged as annular cushion blocks; the cushion block I, the cushion block II, the cushion block III and the cushion block IV are in same outer edge radius; the inner edge radius of the cushion block II is 1.27 times of the inner edge radius of the cushion block I. The heating bracket for the flask has the advantages that the defects of the prior art are overcome and the structure design is reasonable and novel.

Description

technical field [0001] The invention relates to a flask heating support, which belongs to the field of teaching equipment. Background technique [0002] So far, when heating round-bottomed flasks in the laboratory, there are mainly the following forms. The first is to heat the round-bottomed flask with asbestos mesh, the second is to use an electric heating mantle, the third is to heat through an oil bath, and the third is to use an electric heating jacket. Four are heated by a water bath. These heating methods more or less have many problems such as inconvenience, poor thermal insulation performance, slow temperature rise, uneven heating, uncleanness, danger, etc. Aiming at the problems existing in the prior art, a round bottom flask heating device has been researched and designed. Thereby it is very necessary to overcome the problems existing in the prior art. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be so...
