Description

Small-size chemical experimental utility box

The utility model belongs to a kind of small utility chemical test case that chemistry teaching and scientific research are used.

General chemical test carries out on the laboratory test platform, tests required instrument and medicine and mostly is placed on the testing stand or on the instrumented medication frame, testing stand and instrumented medication frame can't arbitrarily carry.Current our national expenditure on education is limited, some school particularly middle school, small towns, the secondary school of agriculture and all kinds of vocational school, the broadcasting school etc. in rural area can not set up chemistry laboratory a period of time, therefore, student's learning chemistry, owing to not having or lacking experimental condition, just stay and read to memorize mechanically, lose contact with reality, the manipulative ability extreme difference of test, this is the urgency problem to be solved that above all kinds of school exists on chemistry teaching.

Agricultural production wants to further develop, and improves output, and main fibrous root is taked the measure of suiting the remedy to the case according to the field scientific research.The field scientific research is the indispensable means that the agro-technician instructs production.Therefore, the agro-technician must possess the miniature instrument that can carry of cover and is used for field diagnosis and test.

The purpose of this utility model is in order to adapt to chemistry class tests such as middle school, small towns, the secondary school of agriculture, all kinds of vocational school, broadcasting school and to impart knowledge to students and the agro-technician designing at the outdoor needs that aspects such as soil plant, water quality are diagnosed, tested.Provide a kind of employing miniature instrument and semimicro experimental technique to combine, the instrument low cost, dosage is few, saves experiment fees, small volume and less weight, the small utility chemical test case that is easy to carry about with one.

The utility model by case at the bottom of, case lid, drawer type test stand and little drawer four parts form.Be inclined-plane opening cuboid at the bottom of the case, inside is stepped construction at the bottom of the case.For convenience of explanation, interior rear portion is first rank at the bottom of the regulation case, and the anterior left side is second rank, and the right side is the 3rd rank.One, a lattice plate all is equipped with in the second order top, has a plurality of through holes on the lattice plate; Lay a rack for test tube on the 3rd rank, there is a lattice plate with holes the rack for test tube top, and this rack for test tube can take out and put into.As further feature, rack for test tube base plate the place ahead is fixed with many buttress shafts, is used for inserting test tube.The front lower place holds little drawer to a cavity at the bottom of the case, and also there is a cavity back lower place, holds drawer type test stand.Respectively there is one deck lattice plate on the left and right both sides of drawer type test stand.Have a plurality of through holes on the lattice plate of the left side, be used to place reagent bottle.The middle part has one lateral opening on the lattice plate of the right.As further feature, fix a tripod above the lattice plate of the right, place alcolhol burner below.In vertical panel inside, the right of drawer type test stand, level is equipped with a circular pillar, and the test tube buret holder can insert on it during test, and there is a nut vertical panel outside, can turn fixed support.

Case lid also is an inclined-plane opening cuboid, on case lid is buckled at the bottom of the case a FCL.Case lid is connected with hinge with back at the bottom of the case, and the front fastens with box fastener, can open and can close; Case lid is connected with folding chain with two inboards at the bottom of the case, and the case lid inner face is equipped with a plurality of location latch closure, and a metal lifting handle is arranged above the case lid, and tetra-pack has the metal box angle.

Below in conjunction with accompanying drawing details of the present utility model is described in detail.

Fig. 1 is the stereogram of small utility chemical test case.Wherein: the 1-case lid, 2-locatees latch closure, at the bottom of the 3-case, 4,5,6-lattice plate, 7-buttress shaft, 8-drawer type test stand, the little drawer of 9-, 10-rack for test tube.

Fig. 2 is the stereogram of drawer type test stand in the chamber shown in Figure 1.Wherein: 11,12-lattice plate, 13-tripod, 14-L type test tube buret holder, 15-chuck, 16-support plate, 17-circle pillar.

At the bottom of the case in (3) on first rank the left side of check board (4) big hole is arranged, put one in 100ml beaker, put one in 50ml beaker in the 100ml beaker, put one of little triangular flask in the 50ml beaker; Before and after the big hole slot is arranged respectively, respectively put one of surface plate.There are totally ten of two row's small garden holes on lattice plate (4) the right, is used to put reagent bottle, in addition, in the middle of two row's small sircle holes, also has totally four of the littler circular holes of a row, is used to put glue head dropper.On the lattice plate (5) on second rank one of big hole is arranged, seven of small sircle holes (being distributed in around the big hole), big hole is put wash bottle, small sircle hole place respectively hairbrush, tweezers, porcelain transfer angle, each one in 25ml volumetric flask, funnel, little graduated cylinder, glass bar.Lay rack for test tube (10) on the 3rd rank, there is a lattice plate (6) top of rack for test tube (10), have on it two row totally 16 be used to lay small test tube for a short time; In addition, also have a row totally nine buttress shafts (7) in base plate the place ahead of rack for test tube (10), so that insert small test tube.There is a little drawer (9) front lower place of (3) at the bottom of the case, one of drop porcelain plate wherein is housed, small steelyard claims one, each one of the big or small rubber stopper of one of long rubber tube, two of short rubber tubes, carrying pipe, four of little glass spoons, glass point are chewed two of two, 90 ° curved glass tubes of two, 120 ° curved glass tubes, two of straight glass tubes.There is a cavity (3) back lower place at the bottom of the case, is used to hold drawer type test stand (8).Left and right two sides of drawer type test stand (8) respectively have one deck lattice plate.Totally 10 of two rounds are arranged on the lattice plate (11) on the left side, be used to put reagent bottle; There is mouth on one side at lattice plate (12) middle part on the right, fixes a tripod (13) above, and an alcolhol burner is put in the below; A L type test tube buret holder (14) that can arbitrarily take out is arranged on the drawer type test stand, and L type test tube buret holder (14) is made up of chuck (15) and support plate (16).As further feature, chuck (15) plane becomes 90 ° of angles with support plate (16) plane, and a notch is arranged on the support plate; In addition, level is equipped with a circle pillar (17) on the vertical panel on drawer type test stand the right, during test, the board slot mouth of L type test tube buret holder inserts on the circle pillar, both can erect, and can arbitrarily rotate into certain angle again, turn the outer nut of vertical panel, support can be fixed.
