Abstract
A kind of connecting vessel experimental facility, including linker ontology, the container that the linker ontology is interconnected by several bottoms and size shape is different are constituted, it is characterised in that: further include the riser and syringe for having pedestal, being fixed on the base；The linker ontology is connected on riser, and the bottom sidewall of the linker ontology is additionally provided with water nozzle, and the water nozzle is connected to by hose with the syringe.Beneficial effect is: pushing and pulling the piston of syringe, can continuously increase and decrease the water in linker, observes liquid level in different height, whether the liquid level in each container still maintains equal, obtains convictive conclusion after facilitating many experiments.The constant situation of conventional apparatus water is changed, is tested in dynamic change, it is not only more rigorous on logic of science, experiment interest is also enhanced, structure is simple, at low cost in addition, has good popularization and application foreground.
Description
Technical field
The utility model belongs to Middle School Physics Instrument technology field more particularly to a kind of connecting vessel experimental facility.
Background technique
Linker is the important content of Physics Course, and the container that several bottoms interconnect injects same liquid, in liquid
The liquid level of each container always remains in same level in linker when body does not flow.
Common experiment equipment is constituted as shown in Figure 1,4 shapes, transparent pipe not of uniform size are interconnected in bottom
The shortcomings that linker, the linker, is:
First is that the stability of device is poor: the conical lower portion of linker is plugged in disc base, and linker is most on the market
It is made of glass, is tightly afraid of very much broken, slightly pine can tilt.
Second is that water flood operations are inconvenient: due to cost etc., the size of entire teaching aid is smaller for estimation, causes bore maximum
Right side pipe nozzle also very little, need that colored water could be injected by tools such as funnels in advance；In addition, due to colored water (one
As with red ink) be easy to dye in hand or clothes, but also be it is disagreeable be difficult to clean, cause people to operation of pouring water have to
Touch mood.
Third is that be difficult to change water number, be not easy to many experiments, description of test power is poor: by above-mentioned apparatus stablize it is poor,
Then the disadvantage of water flood operations inconvenience is taken it is found that instructors are all " carefully " to install water in linker in advance
Take classroom to, make the liquid level in each container of observation of students whether equal, then it is hand-held make its inclination, whether observe each liquid level equal,
That is, can at most observe liquid level 2 times.Since device stabilization is poor, linker is smashed when once having teacher to pour water, in addition
Water flood operations are inconvenient, and teachers is caused not change the water in linker in experimental field, and student cannot also observe water
After amount changes, it is equal whether liquid level is also able to maintain, and in scientific research, if being unable to many experiments, obtained conclusion is
It is difficult convictive.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of connecting vessel experimental facility, it is desirable that can be very convenient
Ground change its interior liquid number, with observe under different height, whether the liquid level in each container still equal.
Used technical solution is the utility model to solve above-mentioned technical problem:
A kind of connecting vessel experimental facility, including linker ontology, the linker ontology interconnects by several bottoms,
And the different container of size shape is constituted, it is characterised in that: further include have pedestal, the riser that is fixed on the base and
Syringe；The linker ontology is connected on riser, and the bottom sidewall of the linker ontology is additionally provided with water nozzle, the water
Mouth is connected to by hose with the syringe.
Compared with prior art, the utility model has the following beneficial effects: linker is fixedly connected on riser, riser
Roomy pedestal is had, whole device has good stability, do not break the worry of linker；Push and pull the work of syringe
Plug can continuously increase and decrease the water in linker, observe liquid level in different height, whether the liquid level in each container is still protected
It holds equal, obtains convictive conclusion after facilitating many experiments.The piston for pushing and pulling syringe, is easy to grasp speed, avoid
The shaking of the water surface in linker has good liquid level stationarity.The constant situation of conventional apparatus water is changed, in dynamic change
In tested, it is not only more rigorous on logic of science, also enhance experiment interest, structure is simple, at low cost in addition, has
Good popularization and application foreground.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing linker；
Fig. 2 is the structural schematic diagram of the utility model；
In figure: 1 pedestal, 2 risers, 3 containers, 4 connecting bands, 5 water nozzles, 6 elastic strips, 7 hoses, 8 syringes, 9 pistons.
Specific embodiment
As shown in Fig. 2, 3 structure of container that linker ontology is interconnected by several bottoms and size shape is different
At.Linker ontology is connected on riser 2, and the corresponding position on riser 2 is provided with eyelet, and wearing tape splicing 4 in succession can be by linker
Bottom be strapped on riser 2；It wears and connects elastic strip 6 and the top of linker can be strapped on riser 2.It can also use other
Linker is fixedly connected on riser by mode, such as clipping, cluster.Roomy pedestal 1 is equipped with below riser 2.
The bottom sidewall of linker ontology is additionally provided with water nozzle 5, and water nozzle 5 is connected to by hose 7 with syringe 8.
