Abstract
The utility model relates to a teaching demonstration device, particularly a demonstration device for teaching temperature reading, which comprises a bottom bracket, wherein, the front face of the bracket is provided with an installing groove; a flexible liquid pipe is installed in the installing groove through a positioning mechanism; the lower part of the flexible liquid pipe is connected with an injection mechanism on the outer side of the bracket. In the utility model, the flexible liquid pipe can adopt a disposable transfusion pipe or the other plastic pipe; the injection mechanism can adopt an injector; therefore, the utility model has the advantage of very low cost. When the utility model is used, a plunger piston of the injector is pushed and pulled, and liquid in the flexible liquid pipe raises or lowers to the required height according to the required speed of demonstration; thus, the changed speed of a liquid column can be quick; besides, the liquid column can make the speed greatly change according to requirements to achieve the demonstration effect. The utility model also has the characteristic of easy operation.
Description
Affiliated technical field
The utility model relates to a kind of teaching demonstration device, particularly a kind of teaching temperature reading demonstration device.
Background technology
At present, in physical teaching course, when telling about the temperature registration, the teacher is general, and the serviceability temperature meter is directly explained, no assistant teaching aid.General thermometer is because the registration range is little, and variation is slower, thereby the demonstration weak effect, is unfavorable for that the beginner uses.
Summary of the invention
The purpose of this utility model provides the teaching temperature reading demonstration device that a kind of with low cost, registration variation range changes greatly, the registration variation is fast.
The utility model comprises lower supporter, and the support front surface has mounting groove, and flexible liquid pipe is loaded in the mounting groove by detent mechanism, and its underpart is connected with support injection mechanism outward.Flexible liquid pipe can adopt one-time infusion tube or other plastic tube in the utility model, injection mechanism then can adopt syringe, therefore, cost of the present utility model is extremely low, the plunger of push-and-pull syringe then can make the liquid in the flexible liquid pipe comply with required speed rising or be reduced to required height according to the demonstration needs, so the pace of change of fluid column can be very fast in use, it can also make its amplitude of variation bigger as required, to reach the demonstration effect.The utility model also has the characteristics of processing ease.
Support in the utility model can be structure as a whole, and also can and be fixed on the support plate on the base and be fixed on the clamping plate of locating support plate leading flank both sides by base and form, and forms mounting groove between two clamping plate.
For consistent with general thermometer, should be provided with vacuole in liquid pipe bottom, liquid pipe, vacuole are connected by three-way pipe with injection device.
In addition, the detent mechanism of above-mentioned flexible liquid pipe can be two ends and is fixed on spacer on the support, also can be on the support front surface fixedly transparent panel realize this purpose, in the time of on having aforesaid clamping plate on the support, transparent panel is fixed on the front surface of two clamping plate.In addition, indicating graduation of the present utility model can directly be made on the support, also can accompany the scale marker between transparent panel and support, in the structure of above-mentioned use clamping plate, then can be between transparent panel and at least one clamping plate and accompanies the scale marker.
Description of drawings
Fig. 1 is a schematic perspective view of the present utility model;
1-base among the figure, 2-syringe, 3-scale marker, 4-clamping plate, 5-transparent panel, 6-support plate, the flexible liquid pipe of 7-, 8-vacuole.
Embodiment
As shown in the figure, the transparent panel 5 of present embodiment support and rack-mount flexible liquid pipe 7 and flexible liquid pipe 7 front sides is formed.Support comprises the support plate 6 of base 1 and base 1 top, forms mounting groove between clamping plate 4, two clamping plate 4 of each bonding glass material of both sides of support plate 6 front surfaces, and flexible liquid pipe 7 is positioned at wherein, and it is gone to the bottom and has vacuole 8.The three-way pipe that is connected with the bottom of vacuole 8 and flexible liquid pipe 7 passes clamping plate 4 and is connected with syringe 2.Be bonded with scale marker 3 on the front surface of clamping plate 4 of present embodiment, be stained with transparent panel 5 on the front surface of this layer front surface, another clamping plate, transparent panel 5 is with the front side sealing of mounting groove.
