The invention discloses a comprehensive chemical experiment box for middle school students. The comprehensive chemical experiment box comprises an equipment box, a reagent box and a guide book, wherein the equipment box comprises a box body and a cover; a first accommodating groove is arranged on the inner side of the cover, the guide book is arranged in the first accommodating groove, a glass cover plate capable of being opened and closed is arranged on the first accommodating groove, and a lifting handle is hinged to the cover; the lifting handle comprises an extension arm and two fixed arms, the two fixed arms are hinged to the two sides of the cover, the extension arm is in a door shape, the two ends of the extension arm are both provided with telescopic holes, and the two fixed arms are respectively arranged in the two telescopic holes in a sliding mode; fixing assemblies used for fixing the extension arm are arranged at the two ends of the fixed arms, and each fixing assembly comprises a fixed block and a first spring; a fixing groove is arranged at one end of each fixed arm, and two fixing holes are arranged on a lateral wall of each telescopic hole. The guide book is arranged in the first accommodating groove, then the guide book is partitioned by the glass cover plate, chemical reagents are prevented from being splashed to the guide book in experiments, and the guide book is prevented from being corroded.
Description
technical field [0001] The present invention relates to a kind of experimental equipment, more specifically relates to a kind of comprehensive chemical experiment box used by middle school students. Background technique [0002] Experiment is an important part of improving the quality of general chemistry teaching. There are many kinds of chemical reactions, which require a lot of chemical experiment equipment. Most of the current chemical experiment equipment is placed in the experiment box, which is convenient for students to take and carry the whole set. [0003] The instruction manual is needed during the experiment, so as to complete the experimental steps correctly, but during the experiment, chemical reagents are often splashed on the instruction manual, corroding the instruction manual. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a comprehensive chemical experiment box for midd...
