Description
Technical field
The utility model relates to a kind of miniature deformation experimental demonstration device, especially a kind of for observing the experimental demonstration device of flat-objects miniature deformation.
Background technology
Have a lot of abstract concept to observe in physical phenomenon, such as power can change in the lecture experiment of the shape of object, and when experiment thing is some hard objects, its phenomenon is often difficult to observation.Existing experimental demonstration device generally comprises a vial, liquid is full of in this vial, described glass bottle opening sealing installation one is with the sealing-plug of glass tubule, and when experimenter presses vial, liquid level then can rise along glass tubule thus reach the experiment purpose of the stressed rear generation deformation of demonstrating glass.But the experimental subjects of above-mentioned experiment for just hard bottle, and because the impact of experimental situation often can cause the amplitude of liquid surface lifting in bottle less in experimentation, this just causes its experimental result not easily to be observed, or even the failure of an experiment.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of experimental subjects wider, and it is a kind of for observing the experimental demonstration device of flat-objects miniature deformation that experimental result is more convenient for observing.
The utility model is achieved through the following technical solutions:
A kind of for observing the experimental demonstration device of flat-objects miniature deformation, it is characterized in that: comprise the uncovered liquid case that an opening is smooth, the side wall lower ends of this uncovered liquid case connects a vertical tubule by a cross connection pipe one, liquid case internal diameter is more than or equal to capillary inside diameter, liquid is filled with in liquid case and tubule, at the piston plate that liquid case upper end open place setting-in one external diameter is identical with liquid case internal diameter, the vertical height being vertically highly more than or equal to described liquid case upper end open of this piston plate upper surface, this piston plate upper surface is for placing flat-objects.
And described liquid case internal diameter is much larger than described capillary inside diameter.
And in described tubule, liquid level is floating is equipped with a reflecting piece, and the tubule opening part side above this reflecting piece installs a LASER Light Source, and this LASER Light Source projects to described reflecting piece.
And be provided with one above described LASER Light Source in order to receive the shadow shield of reflects laser, this shadow shield lower surface is evenly shaped with scale along the direction of motion of reflects laser.
Advantage of the present utility model and good effect are:
1, in this experimental demonstration device, the opening of uncovered liquid case is smooth places the smooth object in various bottom surface, thus can demonstrate the deformation process of more experimental subjectss; Amplified by the change of liquid level in tubule in the liquid deformation useful effect of experimental subjects can filled in liquid case by piston plate, conveniently to be observed.
2, in this experimental demonstration device, the internal diameter of uncovered liquid case much larger than the internal diameter of tubule, thus makes experimental result more obvious.
3, in this experimental demonstration device, in tubule, the floating reflecting piece be equipped with of liquid level can reflect according to the light of the change of liquid level in tubule to laser light source projects, experimental result secondary can amplify by the scale coordinating shadow shield lower surface to make, more be conducive to the observation of experimental result, and quantitatively can calculate the change of experimental subjects volume.
In the utility model, the smooth uncovered liquid case of opening can place the smooth object in various bottom surface, thus demonstrates more experimental subjects; Uncovered liquid case coordinates tubule can more obvious qualitative lecture experiment result; The volume change calculating experimental subjects generation deformation generation that in tubule, the floating reflecting piece cooperation LASER Light Source be equipped with of liquid level and the graduated shadow shield of band can be quantitative by calculating.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cut-open view in Fig. 1 experimentation;
Fig. 3 is the A portion enlarged drawing of Fig. 2.
Embodiment
Elaborate to the utility model below by embodiment, described embodiment is illustrative, and nonrestrictive, can not limit protection domain of the present utility model with this.
A kind of for observing the experimental demonstration device of flat-objects miniature deformation, of the present utility modelly to be characterised in that, comprise the uncovered liquid case 9 that an opening is smooth, the side wall lower ends of this uncovered liquid case connects a vertical tubule 7 by a cross connection pipe one, liquid case internal diameter is more than or equal to capillary inside diameter, liquid 4 is filled with in liquid case and tubule, at the piston plate 2 that liquid case upper end open place setting-in one external diameter is identical with liquid case internal diameter, the vertical height being vertically highly more than or equal to described liquid case upper end open of this piston plate upper surface, this piston plate upper surface is for placing flat-objects.
Described liquid case internal diameter is much larger than described capillary inside diameter.
In described tubule, liquid level is floating is equipped with a reflecting piece, and the tubule opening part side above this reflecting piece installs a LASER Light Source 6, and this LASER Light Source projects to described reflecting piece 8.
Be provided with one above described LASER Light Source in order to receive the shadow shield 5 of reflects laser, this shadow shield lower surface is evenly shaped with scale along the direction of motion of reflects laser.
Use procedure of the present utility model is:
When the utility model uses, experimenter is first by above floating for the piston plate liquid level 3 being placed in filling liquid in uncovered liquid case, open LASER Light Source, adjustment incident angle is until can receive the projection light of reflecting piece in shadow shield, adjust the upper surface of rear pressing experimental subjects 1, can observe by the change of projection light in the lifting of liquid level in tubule and shadow shield and quantitatively calculate the deformation of the stressed rear generation of experiment thing.
In the utility model, the smooth uncovered liquid case of opening can place the smooth object in various bottom surface, thus demonstrates more experimental subjects; Uncovered liquid case coordinates tubule can more obvious qualitative lecture experiment result; The volume change calculating experimental subjects generation deformation generation that in tubule, the floating reflecting piece cooperation LASER Light Source be equipped with of liquid level and the graduated shadow shield of band can be quantitative by calculating.
