Experimental teaching during person's bioconversion medium is also the important step improved the quality of teaching.Teaching practice for many years proves, is changing
Learn or bioconversion medium during experimental teaching can the effectively observation ability of training student, thinking ability, understandability, from
And preferably help student to hold chemistry or biological knowledge exactly, and training student science can be ground during experiment
Method and rigorous scientism are studied carefully, so as to which solid base is laid in the study and research of chemistry or biological knowledge for high-stage
Plinth.Certainly during student's chemistry or Bioexperiment, also the cooperation awareness of training student, independent consciousness and meaning can be saved
The attainment such as knowledge, so as to the all-round developing service for student.
The presence problems with of prior art：Rack for test tube is the experimental teaching demonstration device that chemistry or biology teachers are commonly used
Material, existing rack for test tube encounter the unconspicuous phenomenon of experimental result when showing experimental result, understand teacher in order to observe
Need hand-held background paper to be placed on test tube side, deal with cumbersome, there is also inconvenience when showing observation of students, showing
Because rack for test tube is inconvenient to hold movement during experimental result, the student only near dais is caused to observe well
Practise, the observation of students away from dais is unclear or even invisible experimental demonstration, the effect of experimental teaching are just had a greatly reduced quality.
Utility model content
The purpose of this utility model is to provide a kind of experimental teaching rack for test tube, to solve to propose in above-mentioned background technology
Rack for test tube bandwagon effect it is undesirable, hold mobile inconvenient problem.
To achieve the above object, the utility model provides following technical scheme：A kind of experimental teaching rack for test tube, including examination
Pipe support base, background board and test tube support column, the rack for test tube base top are provided with rack for test tube bottom plate, the rack for test tube bottom plate
Upper surface side is provided at both ends with support bar, and the upper end of the support bar is provided with test tube slot plate, on the test tube slot plate
Slot is provided with, the background board is arranged among the upper surface of rack for test tube bottom plate, and the upper end of background board is provided with rack for test tube
Handle is held, the test tube support column is arranged on the upper surface side of rack for test tube bottom plate, the upper surface side of the rack for test tube bottom plate
Hydrops groove is provided with, and the upper surface opposite side of rack for test tube bottom plate is provided with test tube constraint groove.
Preferably, by snapping connection between the rack for test tube base and rack for test tube bottom plate.
Preferably, the slot aperture has tri- kinds of specifications of diameter 22mm, 20mm, 17mm.
Preferably, the upper surface that the test tube constraint groove is arranged on rack for test tube bottom plate corresponds to the position of slot.
Preferably, the hydrops groove is arranged on one week of upper surface side test tube support column of rack for test tube bottom plate.
Preferably, it is wave linear structure that the rack for test tube, which holds handle,.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model background board is arranged on slot-side, and encounter needs to use background paper auxiliary when reacting unconspicuous phenomenon
Observation is helped, it is necessary to which different background colours only needs to change corresponding paper, simple to operate, convenience is observed；2nd, this practicality
Rack for test tube is provided with new background board holds handle and facilitate teacher to hold mobile test tube shelf, can allow student in each position in classroom
It can observe clear.
