Description
Technical field
The utility model relates to teaching aid technical field, is specially a kind of chemistry tube frame.
Background technology
Rack for test tube is one of the most frequently used chemical experimental instrument, usually adopts the wooden or bamboo matter shelf of one deck, it has the test tube hole for holding test tubes.In chemical experiment teaching process, rack for test tube is commonly used to holding test tubes so that the change of reagent in observing response process, because rack for test tube is unfavorable for observing without background colour, teacher needs to lift test tube on the other hand, the hand-held a piece of paper gear of another is after test tube, the phenomenon of different experiments is observed by background paper, troublesome poeration, and the easy landing of test tube, be not easy to teaching, rack for test tube can shelve the test tube that chemical substance is housed, the time of GPRS good various chemical reaction when doing experiment, therefore, we must pay close attention to the time in the moment.
Utility model content
The purpose of this utility model is to provide a kind of chemistry tube frame, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of chemistry tube frame, comprise base, projection, female receptacle, test tube hole, groove, standing groove, gripper shoe, electronic clock and white riser, described base is located at the below of whole rack for test tube, described projection is located on base, described female receptacle is located at directly over base, test tube hole is located in inserting plate hole uniformly, the test tube hole pore size that described inserting plate hole is provided with differs, described groove is located on base, groove corresponds to test tube hole and is provided with different sizes, be convenient to the placement of different size test tube, described standing groove is located on the outer end of gripper shoe, the side of described gripper shoe is provided with electronic clock, electronic clock is used for observing time, experimenter is helped to grasp the time of chemical reaction, white riser is located between base and female receptacle, described white riser can be placed the background paper of different colours, be beneficial to the observation to different chemical experiment.
Preferably, described projection higher than the altitude range of base between 1cm-2cm.
Preferably, described groove height is lower than the level height of base.
Preferably, the integrative-structure that is connected by gripper shoe with inserting plate hole of described base.
Preferably, described standing groove is provided with multiple on the supporting plate.
Preferably, the notch of described standing groove and the angle of horizontal plane are 30 °.
Compared with prior art, the beneficial effects of the utility model are: this rack for test tube structure is simple, white riser can place the background paper of different colours, better observation different chemical reaction experiment, the test tube just carrying out chemical reaction is put on rack for test tube, electronic clock can check the time, helps experimenter to grasp the time of chemical reaction, easy to use.
