Abstract
The utility model relates to a chemical test displaying box for middle schools and spare-time schools, comprising a box cover, a box body, four object storage lattices and five drawers, wherein, the inner surface of the box cover is provided with an extended panel which can be turned over downward to comprise a displaying table with the box cover together; the front edge of the box cover is provided with three insert holes; the left side of the box body is provided with a movable bracket. Needful instruments, medicine reagents and specifications of experiments of one hundred and twenty experiments of the junior chemistry are totally put in the box. The box is convenient in carry over and operation and multi-purpose in use. One experiment displaying box can act functions of a laboratory. In addition, the box is small in size, light in weight and simple in manufacture technology.
Description
The utility model relate to a kind of be suitable for just in and the experimental demonstration case that uses in sparetime school's chemistry teaching.
At present, China's breadboard instrument in each middle school, medicine and reagent etc. are generally deposited with big cabinet, chemical experiment is generally all carried out on experiment table, testing required instrument and medicine mostly is placed on the experiment table or on the instrumented medication frame, be unfavorable for carrying, this rural area to the conditions for running a school difference, middle school, mountain area and factories and miness school are far from suitable.
The purpose of this utility model is to provide a kind of rural area, middle school, mountain area and factories and miness school be convenient to carry out chemical experiment, needed instrument, medicine and reagent and description of test book in the junior middle school chemistry experiment all can be packed into, thereby can finish 90 basic experiment, 30 are replenished experiment, and it is rational in infrastructure, volume is little, is convenient to take, but the junior middle school chemistry experimental demonstration case of while double as experimental demonstration table.
Task of the present utility model is finished in the following manner: the experimental demonstration case mainly places lattice by case lid, casing, article and drawer is formed.The case lid inside surface is provided with can turn down the extension board that constitutes demonstration table with case lid jointly, extension board is provided with supporting member, the front edge of case lid is provided with 3 jacks that iron stand is installed, on jack, plug two Metallic rod, mix extension clamp, buret clamp and iron ring etc. can constitute two pairs of iron stands, finish the lecture experiment of more complicated.The casing top is provided with four article and places lattice, and the casing left side is provided with two drawers, and the casing front is provided with two drawers, and the right flank of casing is provided with a drawer.
In addition, the casing left surface is provided with the metal travel(l)ing rest that can place 500 milliliters of Drexel bottles; The both sides upper fixed of casing has belt; Extension board is fixed on the case lid by hasp, also is provided with the location hasp on the supporting member.
Junior middle school chemistry experimental demonstration case of the present utility model can all place case with 120 kinds of needed instruments of experiment, medicine and reagent and description of test books in the junior middle school chemistry, this case is easy to carry, extension board is housed in the case lid, turn down the back and constitute demonstration table jointly with case lid, realized one-object-many-purposes, especially be placed with the preparation sleeve pipe in this case, can guarantee that the teacher connects experimental provision in a short period of time, as long as an experimental box just can play a breadboard function.In addition, this case mainly adopts drawer formula structure, is convenient to taking of instrument, medicine, and no instrument can take out at any time, and volume is little, and in light weight, manufacture craft is simple.This case helps rural area, mountain area and the factories and miness middle school of conditions for running a school difference and strengthens chemical experiment teaching, greatly reduces the spending of chemical experiment.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the synoptic diagram that the utility model uses as demonstration table.
Embodiment: with reference to Fig. 1, Fig. 2, that junior middle school chemistry experimental demonstration case is selected for use is heat-resisting, the layered board material of acid-alkali-corrosive-resisting is as boxboard, makes as the shelf material of China fir.Case lid 1 is connected with casing 14 by hinge 8, be equipped with by hinge 6 on the inside surface of case lid 1 and can turn down and the common extension board 3 that constitutes demonstration table of case lid 1, extension board 3 is fitted by hasp 21 and case lid 1, by hinge 4 support plate 5 is housed on the extension board 3, support plate 5 is fitted by hasp 7 and extension board 3.Be processed with 3 jacks 2 that iron stand is installed on the front edge of case lid 1 and casing 14, when doing experiment, plug 2 Metallic rod temporarily, mix extension clamp, buret clamp and iron ring etc., just constitute two pairs of iron stands, can finish the lecture experiment of more complicated.The top of casing 14 is divided into 9,10,11,20 4 article with the lattice plate and places lattice, and article are placed in the lattice 9 and placed graduated cylinder, test tube, funnel, test-tube brush, test tube clamp, drying tube, round bottom test tube etc.; Article are placed and are placed the simple gas generator in the lattice 10; Can put totally 40 of 30 milliliters of wide-necked bottles and narrow-mouthed bottles in the article placement lattice 11, put No. 1 battery of 6 joints, article are placed in the lattice 20 can put drop bottle and 28 mesoporous metal pipe supports, places 28 glass tubes on the pipe support.Drawer 15,16 is equipped with in the left side of casing 14, can put 2 extension clamps in the drawer 15, also can put crucible tongs, tweezers, iron ring, cross iron, iron sheet folder etc.; Can put Roberval's balance and counterweight in the drawer 16. Drawer 12,13 is equipped with in the front of casing 14, put acid buret, glass tube, glass bar, thermometer, combustion spoon and supporting pipe close and connecting pipe etc. in the drawer 12, can put test tube rack, tank, spirit lamp, tripod, gas bottle, flask, beaker, Erlenmeyer flask etc. in the drawer 13.The right flank of casing 14 is equipped with drawer 19, puts 3 narrow-mouthed bottles in the drawer 19.
In addition, be provided with the metal travel(l)ing rest 18 that can place 500 milliliters of Drexel bottles in the left side of casing 14, can be for needed a small amount of water in the experiment.Belt 17 is equipped with in the top, both sides of casing 14.
