Description
Technical field
The utility model relates to a kind of high school chemistry teaching apparatus, is specifically related to a kind of chemistry teaching solution conductivity demonstration device.
Background technology
When talking about the character of solution in the chemistry teaching, all the electric conductivity of solution is set forth as an important properties.In the test, measure different material and when different conditions, whether have electric conductivity.If every kind of solution is test respectively, time-consuming more, and also experimental phenomena easily obscures, and produces the alienation effect, and contrast effect is not obvious, and the student obscures easily, memory difficulty.
The Chinese patent publication number is CN201616212U, the utility model instructions that open day is on October 27th, 2010 discloses " solution conductivity education demonstrator ", this utility model comprises support body, base plate and solution cup, the end face of support body is provided with socket, the rear side of socket is provided with the plug that is connected with power supply by lead, correspondence is equipped with two electrode bars on the support body of socket below, is placed with the solution cup on the base plate of electrode bar below, and the solution in the solution cup contacts with electrode bar.The solution conductivity education demonstrator of this utility model is compared with prior art, have reasonable in design, simple in structure, be easy to processing, easy to use, characteristics such as the contrast of clear, the experimental phenomena of demonstration is obvious.But this utility model demonstration effect is still comparatively single, and the effect that electrode bar conducted electricity of conducting solution that can not comprehensively compare variable concentrations and different conductive material can not effectively help the student to understand and use classroom instruction knowledge.
The utility model content
The purpose of this utility model is can not comprehensively compare, demonstrate deficiencies such as weak effect at existing solution conductivity education demonstrator, provides a kind of and can comprehensively compare the conductive effect of the contact rod of variable concentrations liquid and different conductive material, the chemistry teaching solution conductivity demonstration device of good demonstration effect.
The purpose of this utility model realizes by following technological means: a kind of chemistry teaching solution conductivity demonstration device, include support body, support body is provided with 1-6 group electrode bar, every group of electrode bar is connected with demonstration lamp, plug respectively, the following solution cup that also is provided with of every group of electrode bar, described 1-6 group electrode bar is set to the electrode bar of different conductive material respectively, and is arranged with labeling at the corresponding demonstration lamp that is connected, and also is provided with cup on the described solution cup and pastes.
Described support body bottom also is provided with telescope support and connects the platform that is provided with.
Compared with prior art the utlity model has following tangible advantage: this chemistry teaching can comprehensively compare the conductive effect of the contact rod of variable concentrations liquid and different conductive material with the solution conductivity demonstration device, Zheng Ti good demonstration effect more can effectively help the student to understand classroom instruction knowledge like this.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, the 1-plug, the 2-support body, 3-demonstrates lamp, the 4-labeling, the 5-electrode bar, 6-solution cup, the 7-cup pastes, 8-platform, 9-telescope support.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is described in further detail:
A kind of chemistry teaching solution conductivity demonstration device as shown in Figure 1, include support body 2, support body 2 is provided with 1-6 group electrode bar 5, every group of electrode bar 5 is connected with demonstration lamp 3, plug 1 respectively, the following solution cup 6 that also is provided with of every group of electrode bar 5, described 1-6 group electrode bar 5 is set to the electrode bar 5 of different conductive material respectively, and is arranged with labeling 4 at the corresponding demonstration lamp 3 that is connected, and also is provided with cup on the described solution cup 6 and pastes 7.Be provided with like this, this chemistry teaching can be by the electrode bar 5 that is provided with different conductive material with the solution conductivity demonstration device, cooperate molten conductive liquid several groups of variable concentrations or same concentrations again, and respectively at labeling 4, cup pastes on 7 and does corresponding mark, after the energising, the chiaroscuro effect of further observing the demonstration lamp 3 of electrode bar 5 in identical conduction solution of different conductive material is a conductive effect, perhaps observe the relatively conductive effect of electrode bar 5 in different conducting solutions of identical conduction material, the conductive effect that so just can comprehensively compare the contact rod 5 of variable concentrations liquid and different conductive material, Zheng Ti good demonstration effect more can effectively help the student to understand classroom instruction knowledge like this.
Described support body 2 bottoms also are provided with telescope support 9 and connect the platform 8 that is provided with.Be provided with like this, can change the conducting solution in 5 times different solution cups of electrode bar 6 more easily.
In a word, the utility model chemistry teaching that a kind of conductive effect that can comprehensively compare the contact rod of variable concentrations liquid and different conductive material, good demonstration effect be provided is with the solution conductivity demonstration device.The above; it only is a part of embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
