Description
Technical field
This utility model relates to a kind of chemistry teaching apparatus, specifically a kind of chemical apparatuses rack.
Background technology
Chemical apparatuses rack is one of the most frequently used chemical experimental instrument, generally adopts one layer of wooden or bamboo matter shelf, it has the placing trough for placing various chemical apparatuses; In chemical experiment teaching process, often need to measure the pH value of liquid, owing to existing chemical apparatuses rack is unfavorable for observing without background colour, teacher needs to lift test tube on the other hand, the hand-held a blank sheet of paper of another keeps off after test tube, and the printing opacity by white reflects that the real phenomena of reagent in test tube changes, troublesome poeration, and the easy landing of test tube, it is not easy to teaching; It addition, some bottle of class chemical experiment apparatus, it is not fixed easily, carries inconvenience, impact teaching speed.
Utility model content
The purpose of this utility model is in that to provide a kind of chemical apparatuses rack, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of chemical apparatuses rack, including pH reagent paper placing trough, drop bottle dropper placing trough, graduated cylinder placing trough, Glass rod placing trough, test tube placing trough and foreign material placing trough; Described pH reagent paper placing trough is positioned at the right part of this chemical apparatuses rack, and pH reagent paper placing trough rear portion is provided with drop bottle dropper placing trough, and the left part of pH reagent paper placing trough and drop bottle dropper placing trough is sequentially provided with graduated cylinder placing trough, Glass rod placing trough and test tube placing trough; The left part of graduated cylinder placing trough, Glass rod placing trough and test tube placing trough is provided with foreign material placing trough; The height of described pH reagent paper placing trough is lower than drop bottle dropper placing trough and test tube placing trough; The height of described graduated cylinder placing trough, Glass rod placing trough and test tube placing trough is stepped to successively decrease successively; Described test tube placing trough frame is provided with a square hole; Described foreign material placing trough frame is provided with four grooves, is provided with a sliding panel in foreign material placing trough frame, and sliding panel is provided with circular hole.
As further program of the utility model: the diameter of described circular hole is more than the diameter of other bottle of class chemical experiment apparatus bottleneck such as flask, conical flask.
As further program of the utility model: described sliding panel is connected by interference fit.
As further program of the utility model: the top of described square hole is provided with pH reagent paper and compares vitta.
The scheme of another step is entered: bottom all placing troughs, be provided with circular groove as this utility model.
Compared with prior art, the beneficial effects of the utility model are:
This utility model simple in construction, multiple functional, safe ready, alleviate the workload of teacher; Dropper, drop bottle and pH reagent paper can be placed on the right side of test tube rack, be prevented effectively from Preparatory work of experiment process and miss part apparatus; This chemical apparatuses rack is provided with pH reagent paper than vitta, facilitates teacher to measure the pH value of liquid, makes experiment convenient, indirectly improves the quality of instruction of teacher; It addition, this chemical apparatuses rack is provided with sliding panel, make to carry instrument safe ready more.
