Description

The very small chemical reagent box

The utility model relates to the very small chemical reagent box that a kind of common junior high school chemistry class lecture experiment is used.

According to the arrangement of State Education Commission's syllabus, offer the chemistry class three grades of junior high school.According to the teaching requirement, in chemistry teaching, to experimentize and demonstrate, the rule that the phenomenon understanding material that makes students pass through chemical change changes, and strengthen the interest of student to chemistry.

But, the chemical reagent of domestic present sale all is big bottled, price is more expensive, and one bottle of available many decades is bought by regular school, causes and overstocks and waste, and the related reagent of chemical experiment and demonstration reaches tens kinds, purchase completely, need a large number of funds, the especially vast rural middle school of general high school can't solve at all, often there be not local the placement even purchased together reagent yet, thereby for want of necessary reagent of many schools and can't carry out chemical experimental courses.Be difficult to finish the requirement of syllabus.

The purpose of this utility model is to overcome the deficiencies in the prior art, solves the excessive problem of chemical reagent Packing Unit, provides that a kind of dosage is little, kind complete, be suitable for the very small chemical reagent box that common junior high school chemistry class lecture experiment is used.

The utility model is achieved in that

It is equipped with a location orifice plate by a casing of being made up of loam cake and nowel in nowel, have several circular holes on the orifice plate of location, is placed with a reagent bottle that reagent is housed in each circular hole of location orifice plate.

In order to impart knowledge to students conveniently, in nowel, also be provided with instrument cases, so that place the experiment apparatus.

The utlity model has following advantage:

1. in conjunction with junior middle school chemistry teaching reality, reagent type and quantity are set, thereby the reagent category is complete, quantity is suitable, can use an academic year for four teaching class demonstrations, experiment one the case, if class purchase a case, can be for four groups' demonstrations, experiment one academic year of use.

2. money order matter and compound are in a case, and Ji Guan looks into, demonstrates, tests in one, are convenient to teaching and use.

3. volume is little, and is in light weight, and price is low, is convenient to deposit, carries and manages, safe and reliable.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

As shown in the figure, the utility model is by a casing of being made up of loam cake 1 and nowel 2, and loam cake 1 is connected with folding or folding material with a side between the nowel 2, and loam cake 1 can be started from nowel 2; Location orifice plate 4 is housed in nowel 2, has 64 circular holes on the orifice plate 4 of location, the quantity of circular hole and diameter can be done corresponding levelling according to actual needs; In each circular hole of location orifice plate 4, be placed with a reagent bottle 3 that reagent is housed; In nowel 2, also be provided with instrument cases 6, so that place the experiment apparatus; Also be provided with elastic cushion 5 on loam cake 1, when loam cake 1 closed with nowel 2, elastic cushion 5 was pressed on the reagent bottle 3, deviate from from the circular hole of location orifice plate 4 to prevent reagent bottle 3; Described elastic cushion 5 can be made of foam block, and loam cake 1, nowel 2, location orifice plate 4 and instrument cases 6 material therefors are not limit, and can use timber, cardboard, leather or plastic or other material to make.

Claims (3)

1. very small chemical reagent box, it is characterized in that, it has a casing of being made up of loam cake (1) and nowel (2), location orifice plate (4) is housed in nowel (2), have several circular holes on the location orifice plate (4), in each circular hole of location orifice plate (4), be placed with a reagent bottle (3) that reagent is housed.
