Abstract
A multifunctional demonstration pipe for chemical experiments includes a transparent tube body, and is characterized in that a transparent tube with a sealed port, which is communicated with the tube body, is integrated on the tube body. Due to the adoption of the technical scheme, the multifunctional demonstration pipe has the advantages of simple structure, convenient operation and convenient demonstration, reduces the operation procedures of experiments, improves the efficiency for experimental teaching, enables experimental effects to be more direct and obvious, increases the interests of students on experiments and stimulates the research enthusiasm of students.
Description
Technical field
The utility model relates to a kind of educational aid, particularly a kind of chemical experiment demonstration pipe.
Background technology
In chemistry teaching in order to express the reacting phenomenon of material intuitively, all need do chemical experiment, the general teat glass that adopts is as the demonstration pipe, the experiment reagent that interpolation will be reacted in teat glass is with the observing response phenomenon, present mode of operation is that hand-held test tube adds a kind of reagent earlier, add another reagent again, two kinds of reagent mix afterreactions begin, at this moment need again the seal of vessel of second kind of medicine is replaced, the Best Times that has delayed the observation of students reacting phenomenon, the teacher also need hand teat glass by student viewing, can obstruct the view like this, be not easy to observe, more than these situations, increased the operating procedure of teacher's demonstration, be not easy to the class demonstration teaching, be unfavorable for that the carry out classroom of student in the limited time probe into, reduced the efficient of experimental teaching.The bottom of teat glass is an arc, can not place, if the mensuration of mass change reaction is arranged, is not easy to use the counter balance weighing.
The utility model content
The purpose of this utility model just provides the multi-functional demonstration pipe of a kind of chemical experiment simple in structure, and it can demonstrate chemical test easily, saves operating procedure, and operation is very easy.
The purpose of this utility model is to realize that by such technical scheme it comprises transparent body, is to be integrally formed with that connect with it and transparent pipe port closed on body.
The utility model splashes into a kind of solution experiments reagent to body and transparent pipe respectively by dropper earlier when demonstration, only need the mouth of pipe position of hand-held body, with the body slight inclination, then two kinds of solution experiments reagent just mix and react, and the observing response phenomenon, demonstrate chemical test easily, save operating procedure, operation is very easy, reduced the operating procedure of experiment, saved the time, improved experimental teaching efficient, made experiment effect more directly perceived obviously.
Owing to adopted technique scheme, the utlity model has advantage simple in structure, easy to operate and that be convenient to demonstrate, it can reduce the operating procedure of experiment, improve the efficient of experimental teaching, make experiment effect more directly perceived obviously, increase the interest of student, the enthusiasm that excites the student to probe into experiment.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is the structural representation of first kind of embodiment of the utility model;
Fig. 2 is the structural representation of second kind of embodiment of the utility model;
Fig. 3 is the structural representation of the third embodiment of the utility model;
Among the figure: 1. body; 2. transparent pipe; 3. support mounting; 4. support bar; 5. base; 6. scale.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model comprises transparent body 1, it is characterized in that: be on body 1 and be integrally formed with it that connect and transparent pipe 2 port closed.
The utility model is when demonstration, earlier splash into a kind of solution experiments reagent to body and transparent pipe respectively by dropper, only need the body slight inclination, then two kinds of solution experiments reagent just mix and react, and the observing response phenomenon, reduced the operating procedure of testing, saved the time, improved experimental teaching efficient, made experiment effect more directly perceived obviously.
Shown in Fig. 2,3, between body 1 and transparent pipe 2, be provided with and support mounting 3.Support mounting 3 and comprise support bar 4 and base 5, an end of support bar 4 is connected with base, and the other end of support bar 4 is connected with body 1 or transparent pipe 2.
When the observing response phenomenon, this support mounting 3 is for the ease of hand-held, and promptly hand-held base slight inclination just can realize that the experiment reagent in body and the transparent pipe mixes mutually, and operation is very easy, avoids blocking of sight line, is convenient to observe, and improved experiment effect; When weighing, this support mounting 3 is to deserve to be called for the ease of directly being placed on balance, reduces the experimental implementation step, has improved experimental teaching efficient; In when experiment heating because support mounting 3 has been arranged, just can be directly to body or/and transparent pipe heats, need not iron stand or test tube clamp, reduced experiment equipment and experimental implementation step, improved experimental teaching efficient.
As shown in Figure 2, support bar 4 is fixed on body 1 or the transparent pipe 2.
As shown in Figure 3, can be threaded between support bar 4 and body 1 or the transparent pipe 2.For the ease of transportation, will support between mounting 3 and body 1 and the transparent pipe and adopt dismountable the connection, during transportation, just pull down support mounting 3, during use, just install support mounting 3.
Shown in Fig. 1,3, be used to have the mensuration of the reaction of Volume Changes for convenience, body 1 is or/and transparent pipe 2 is provided with scale 6.
