Abstract
The utility model discloses a simply simulate magdeburg hemispheres demonstration ware, including the barrel, barrel one end is equipped with first piston, the first piston rod of a hinge joint, and a tailpiece of the piston rod portion is equipped with the first body that colludes, and the barrel other end is equipped with the second piston, the 2nd hinge joint second piston rod, the 2nd tailpiece of the piston rod portion is equipped with the second and colludes the body, and one of them tip of barrel is equipped with the iron ring. Compared with the prior art, the utility model discloses the preparation material is easy, and simple manufacture is with low costs, easy to operate, and the security is strong, and experiment phenomena is obvious, and simulation magdeburg hemispheres experiment that can be fine can demonstrate fully science, demonstrative and practicality. The utility model is used for magdeburg hemispheres experiment operation carries out.
Description
Technical field
The utility model relates to education and instruction technical field, is specifically related to a kind of simple and easy simulation Magdeburg hemispheres demonstrator.
Background technology
At [people teaches version] grade eight physics volume two: during chapter 9 Section three " atmospheric pressure " saves, in order to prove the existence of atmospheric pressure, have in history famous " Magdeburg hemispheres experiment ", we simulate Magdeburg hemispheres experiment in classroom, classmates are very glad to drop into very much and do this experiment, can operate very bothersome, sometimes also unsuccessful, experimental teaching impact for student is larger, quality of instruction can not be ensured, along with development and the innovation of field of Education and teaching technology, quality-oriented education is carried out, the raising of quality of instruction, improvement for all kinds of demonstrating experiment device seems more and more important, for the problems referred to above, ad hoc meter the utility model is solved.
Utility model content
The purpose of this utility model is to provide a kind of material that makes to be easy to get, and make simple, cost is low, easy operation, high safety, experimental phenomena is obvious, can be good at the experiment of simulation Magdeburg hemispheres, the simple and easy simulation Magdeburg hemispheres demonstrator of science, exemplary and practicality can be fully demonstrated.
For achieving the above object, the utility model provides following technical scheme:
A kind of simple and easy simulation Magdeburg hemispheres demonstrator, comprise cylindrical shell, cylindrical shell one end is provided with first piston, first piston connects first piston bar, first piston boom end is provided with the first hook body, and the cylindrical shell other end is provided with the second piston, and the second piston connects the second piston rod, second piston rod end is provided with the second hook body, and one of them end of cylindrical shell is provided with iron ring.
As the further improvement of above-mentioned technology, described cylindrical shell adopts syringe to make.
As the further improvement of above-mentioned technology, it is circular configuration that described first hook body and second hooks body.
Compared with prior art, the beneficial effects of the utility model are: when needing to test, and by firmly pulling the first hook body and second to hook body, reach the object of simulation Magdeburg hemispheres experiment, making material is easy to get, make simple, cost is low, easily operates, high safety, experimental phenomena is obvious, can be good at the experiment of simulation Magdeburg hemispheres, can fully demonstrate science, exemplary and practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-cylindrical shell, 2-first piston, 3-first piston bar, 4-first hook body, 5-second piston, 6-second piston rod, 7-second hook body, 8-iron ring.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
A kind of simple and easy simulation Magdeburg hemispheres demonstrator, comprise cylindrical shell 1, cylindrical shell 1 adopts syringe to make, cylindrical shell 1 one end is provided with first piston 2, first piston 2 connects first piston bar 3, first piston bar 3 end is provided with the first hook body 4, first hook body 4 is circular configuration, cylindrical shell 1 other end is provided with the second piston 5, second piston 5 and connects the second piston rod 6, second piston rod 6 end and be provided with the second hook body 7, second hook body 7 is circular configuration, first hook body 4 and the second hook body 7 lift for staff, and one of them end of cylindrical shell 1 is provided with iron ring 8, and iron ring 8 plays the effect of reinforcing.
During utility model works, get two 100ml syringe pistons and a syringe cylinder, amputate bottom syringe cylinder, sand paper is used to be polished smooth by section, form cylindrical shell 1, and put iron ring and reinforce, first piston bar and the second piston rod being compressed pushes in cylindrical shell 1, when needs are tested, body 7 is hooked by firmly pulling the first hook body 4 and second, reach the object of simulation Magdeburg hemispheres experiment, the utility model makes material and is easy to get, make simple, cost is low, easy operation, high safety, experimental phenomena is obvious, can be good at the experiment of simulation Magdeburg hemispheres, science can be fully demonstrated, exemplary and practicality.
The foregoing is only the utility model preferred embodiment; not thereby embodiment of the present utility model and protection domain is limited; to those skilled in the art; the equivalent replacement that all utilization the utility model instructionss and diagramatic content are made and the scheme that apparent change obtains should be recognized, all should be included in protection domain of the present utility model.
