Description
Technical field
The utility model relates to Physical Experiment field, is specifically related to a kind of Physical Experiment case.
Background technology
In physics teaching, the motion state of object in a vacuum and when there is aerostatic buoyancy, liquid buoyancy is key content, also be difficult point content, student is not easy to understand, in existing experiment instrument, can not intuitively to student show same object in a vacuum and there is aerostatic buoyancy, liquid buoyancy time motion state, the object of equal in quality different volumes in a vacuum and when there is aerostatic buoyancy, liquid buoyancy motion state have again why not with, be unfavorable for that student understands.
Summary of the invention
For overcoming described deficiency, the purpose of this utility model is to provide a kind of Physical Experiment case intuitively showing the motion state of object in different medium of the motion state of object in different medium, equal in quality different volumes.
The utility model solves the technical scheme that its technical matters adopts: a kind of Physical Experiment case, comprise casing, case lid, magnetic steel ball, magnetic block, the backboard perpendicular to bottom surface is provided with in the middle of described tank floor, described backboard two sides is provided with magnetic drawing, described backboard one side upper end is provided with bending chute near left side or right side, described backboard another side is provided with the parabolic type chute of opening upwards, the axis of symmetry of described para-curve chute is located at the centre of backboard, and perpendicular to tank floor, described casing is provided with case lid, described case lid is provided with liquid injection port, bleeding point, the corresponding bending chute upper end of described case lid lower surface, the position of para-curve chute upper end is provided with locating slot one, the position of the corresponding locating slot one of described case lid upper surface is provided with locating slot two.
Further, described casing adopts transparent material.
Further, described magnetic block can put into locating slot.
Further, described magnetic drawing is wrapped with one deck diaphragm seal, prevents by soaked with liquid corrosions such as water, ineffective.
Further, the described magnetic steel ball that two volumes identical in quality are different is at least provided with.
Further, the angle of described bending chute is 110-170 °, and a section of being wherein positioned at below is parallel to tank floor.
The utility model has following beneficial effect: structure is simple, can vacuumize or inject liquid, air in casing, for student shows the motion state of object in different medium, also can show the multiple Physical Experiments such as the motion state of the object of equal in quality different volumes in different medium for student, allow student understand physical motion more intuitively.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the schematic diagram that parabolic chute one side established by the utility model backboard.
In figure, 1 casing, 2 backboards, 21 bending chutes, 22 para-curve chutes, 3 case lids, 31 locating slot two, 32 liquid injection ports, 33 bleeding points, 4 magnetic blocks, 5 magnetic steel balls.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.
According to Fig. 1, a kind of Physical Experiment case shown in Fig. 2, comprise casing 1, case lid 3, magnetic steel ball 5, magnetic block 4, the backboard 2 perpendicular to bottom surface is provided with in the middle of described casing 1 bottom surface, described backboard 2 two sides is provided with magnetic drawing, described backboard 2 one side upper end is provided with bending chute 21 near left side or right side, described backboard 2 another side is provided with the parabolic type chute of opening upwards, the axis of symmetry of described para-curve chute 22 is located at the centre of backboard 2, and perpendicular to casing 1 bottom surface, described casing 1 is provided with case lid 3, described case lid 3 is provided with liquid injection port 32, bleeding point 33, corresponding bending chute 21 upper end of described case lid 3 lower surface, the position of para-curve chute 22 upper end is provided with locating slot one, the position of the corresponding locating slot one of described case lid 3 upper surface is provided with locating slot 2 31.
Further, described casing 1 adopts transparent material.
Further, described magnetic block 4 can put into locating slot 2 31.
Further, described magnetic drawing is wrapped with one deck diaphragm seal, prevents by soaked with liquid corrosions such as water, ineffective.
Further, the described magnetic steel ball 5 that two volumes identical in quality are different is at least provided with.
Further, the angle of described bending chute 21 is 110-170 °, and a section of being wherein positioned at below is parallel to casing 1 bottom surface.
During experiment, if select vacuum state, magnetic block 4 can be put into locating slot 2 31, then magnetic steel ball 5 is put into corresponding locating slot one, then case lid 3 is covered, utilize magnetic block 4, with the suction of magnetic steel ball 5, magnetic steel ball 5 is positioned at chute upper end, aspirating hole is aimed at vacuum pump, gas in casing 1 is extracted out, then magnetic block 4 is rapidly to and takes away, magnetic steel ball 5 falls naturally, then projectile motion is done 21 times along bending groove is sliding, or move reciprocatingly along para-curve chute 22, in the process of motion, magnetic steel ball 5 can leave movement locus automatically on magnetic drawing, then another magnetic steel ball 5 is selected to repeat said process, whether identically observe the movement locus that two magnetic steel balls 5 stay.
Liquid, air can be injected in casing 1, for student shows the motion state of object in different medium, also can show the multiple Physical Experiments such as the motion state of the object of equal in quality different volumes in different medium for student, allow student understand physical motion more intuitively.
The utility model is not limited to described embodiment, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or close technical scheme with the utility model, all falls within protection domain of the present utility model.
