Abstract
The utility model provides a medicine spoon specialized for chemical experiment, which belongs to an auxiliary device for chemical experiment. The structure is characterized in that: a baffle covers an upper surface at the front side of a spoon head; the back part of a spoon handle is provided with external threads; the spoon handle is internally connected with a sleeve through thread connection; the inside of the sleeve is provided with internal threads which are matched with the external threads of the spoon handle; and the outside back end of the sleeve is provided with external threads. Compared with the prior art, the medicine spoon specialized for chemical experiment has the following characteristics: reasonable design, simple structure, convenient use, quick operation and use, convenient medicine fetching, improved teaching quality and efficiency of chemistry, etc.
Description
Technical field
The utility model relates to a kind of chemical experiment assistive device technical field, a kind of specifically chemical experiment special use spoon of getting it filled.
Background technology
At present in the chemical education of school, often need do experiment cooperates the student to understand, the instrument of getting it filled that uses in chemistry laboratory generally all is a spoonful shape spoon head, the length of its kettleholder immobilizes, when medicine is less in the bottle when bottle is higher, it is very inconvenient to get it filled from bottle, in the process of getting it filled because spoon head is an open type, the chemicals of being got is unrestrained easily, according to the laboratory operation rules, when in vitro adding chemicals, must tilt test tube or traverse earlier, the spoon head that fills medicine is extend in vitro, and upset spoon head is poured the chemicals in the spoon head in vitro into again.But, if in the time of will in it, adding medicine when in vitro filling liquid, according to operational procedure, should make the spoon head to greatest extent near liquid level, the test tube that will fill liquid exactly tilts, may cause invisible spectro liquid to flow out like this, perhaps just that test tube is upright, directly chemicals is poured into from the top of test tube, chemicals is sticked on the test tube wall, cause the inaccurate of chemical experiment, repeatability is bad.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of simple in structure, chemical experiment special use easily of getting it filled spoon of getting it filled is provided.
The technical solution of the utility model realizes in the following manner, this chemical experiment special use spoon of getting it filled, its structure comprises spoon head, kettleholder, a described spoon front side upper surface is coated with baffle plate, rear portion at kettleholder is provided with external screw thread, described kettleholder is threaded in the sleeve pipe, is provided with the internal thread that matches with the kettleholder external screw thread in the sleeve pipe inboard, and the rearward end of outside of sleeve is provided with external screw thread.
Be provided with lever on described kettleholder, the sleeve pipe.
The beneficial effect that the utility model is compared with prior art produced is:
Chemical experiment special use of the present utility model get it filled spoon have simple in structure, easy to use, characteristics such as be skillfully constructed, upper surface is coated with cover plate in the front side of spoon head, avoid institute's thing of getting it filled unrestrained, accurately obtain chemicals, good reproducibility, kettleholder is the selectivity joint sleeve as required, so just can be applicable to the chemical medicine bottle of differing heights, be of value to the carrying out of chemical experiment, the agility that it is manipulated, assurance is got it filled conveniently, improves chemistry teaching quality and efficiency of teaching.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Mark in the accompanying drawing is represented respectively:
1, spoon head, 2, baffle plate, 3, kettleholder, 4, lever, 5, external screw thread, 6, internal thread, 7, sleeve pipe.
The specific embodiment
Below in conjunction with accompanying drawing the chemical experiment special use of the present utility model spoon of getting it filled is done following detailed description the in detail.
As shown in Figure 1, this chemical experiment special use spoon of getting it filled, its structure comprises spoon 1, kettleholder 3, described spoon 1 a front side upper surface is coated with baffle plate 2, be provided with external screw thread 5 at the rear portion of kettleholder 3, described kettleholder 3 is threaded in the sleeve pipe 7, is provided with the internal thread 6 that matches with kettleholder external screw thread 5 in sleeve pipe 7 inboards, the rearward end in sleeve pipe 7 outsides is provided with external screw thread 5, is provided with lever 4 on described kettleholder 3, the sleeve pipe 7.
In actual process of carrying out chemical experiment, at first according to the number of connection of the high selection sleeve pipe 7 of bottle, as shown in Figure 1, kettleholder 3 places connect a sleeve pipe 7, the another set of pipe 7 of these sleeve pipe 7 screw thread sockets, getting it filled with spoon 1 then get final product, manipulates fast, assurance is got it filled conveniently, improves chemistry teaching quality and efficiency of teaching.
