Heating device for physical test

Abstract

The invention relates to the technical field of heating devices, in particular to a heating device for a physical test. The heating device comprises a base, wherein a T-shaped groove is formed in thecenter of the upper side of the base; a T-shaped threaded rod is rotationally arranged in the T-shaped groove; a rotary switch is arranged on the outer side of the T-shaped threaded rod in a sleevingmanner; a threaded pipe is arranged on the outer side of the upper end of the T-shaped threaded rod in the sleeving manner; a putting board is fixedly supported at the upper side of the threaded pipe;limiting plates are fixed at two ends of the upper side of the base; sliding rails are respectively arranged at certain sides, which are opposite to each other, of the limiting plates; sliding blocksare arranged in the sliding rails in a sliding manner; in addition, the other sides of two sliding blocks are respectively fixed at two sides of the putting boards; a limiting mechanism is arranged at the upper side of the putting board; a supporting plate is fixed at the upper ends of the two limiting plates; a heating hole is formed in the center of the upper side of the supporting plate in a penetrating manner; a threaded rod is fixed at one end of the upper side of the supporting plate; a threaded sleeve is arranged on the threaded rod in a sleeving manner. The heating device disclosed bythe invention has the advantages that the position of an alcohol lamp can be quickly adjusted, a heating object can be able to contact with the outer flame of the alcohol lamp and the heating efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of heating devices, in particular to a heating device for physical tests. Background technique [0002] In physics classes, it is often necessary to do various heating tests. In the heating test, a heating rack is usually used. The alcohol lamp and the object to be heated can be supported by the heating rack. However, the heating rack in the prior art is a simple The iron frame body is inconvenient to adjust the heating position of the alcohol lamp, so the outer flame of the alcohol lamp cannot be used for heating, and the heating efficiency is relatively low. For this reason, we propose a heating device for physical experiments. Summary of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a heating device for physical testing. [0004] In order to achieve the above objectives, the present invention adopts the following technical solutions: [0005...
