[utility model content]
In order to overcome the above-mentioned shortcoming of existing teaching equipment, the utility model provides a kind of testee suffered buoyancy size in liquid that can intuitively reflect particularly to equal the Archimedes principle demonstration device of the suffered gravity of liquid that it arranges.
The technical scheme that its technical matters that solves the utility model adopts is: the Archimedes principle demonstration device, comprise base and support, on base, be provided with a liquid spilled cup, a side is provided with a movable wheel shaft above described support, this activity wheel shaft is connected with a buoyancy spring balance, and the steelyard hook of buoyancy spring balance articulates testee, and testee is with during liquid spilled cup is relative, the opposite side heavy spring balance of a liquid that suspended above support, the steelyard hook of the heavy spring balance of this liquid is mounted with one and is subjected to the liquid measure cup.
Described liquid spilled cup is provided with and overflows mouth, and this outlet end that overflows mouth stretches in the measuring cup.
One side of described buoyancy spring balance is connected with anti-sway control lever, embedded chute and the embedded flexible connection of support that the other end of this anti-sway control lever is provided with by support one side.
The beneficial effects of the utility model are: the utility model compact conformation, reliable, and simple to operate, understand, save time, when being operated, the student without any confusion, can understand wherein reason at a glance, be convenient to record simultaneously, measurement data is comparatively accurate, thing tuple value G
1With cup tuple value G
2Buoyancy spring balance registration F
1With the heavy spring balance registration of liquid F
2The data contrast be convenient in record simultaneously, and the utility model is a combined moving type device, and it is convenient to keeping and carries, and this instrument is made miniaturization, can change lecture experiment into student's grouping experiment.Be adapted to apply to all middle and primary schools of the whole nation.

The utility model liquid spilled cup 3 is provided with and overflows mouth 4, and this outlet end that overflows mouth 4 stretches into and is subjected in the liquid measure cup 2, and when making testee 6 immerse in the liquid, the liquid that is flowed out from liquid spilled cup 3 can all flow into exactly and be subjected in the liquid measure cup 2.
In order to prevent the rolling pendulum of buoyancy spring balance 8, these buoyancy spring balance 8 one sides are connected with anti-sway control lever 9, at the embedded chute that support 2 one sides are provided with, and the other end of this anti-sway control lever 9 and support 2 embedded flexible connections; In order to control the immersion degree of testee 6 in liquid, can positioner be set at the rotary part of movable wheel shaft 10, control moving up and down of testee 6.
Operation steps in actual the use is: turn movable wheel shaft 10, buoyancy spring balance 8 is heightened, hang up properly testee 6 on buoyancy spring balance 8 steelyard hooks; Hang up the empty liquid measure cup 5 that is subjected to for 7 times at the heavy spring balance of liquid, measuring cup is lower than liquid spilled cup 3 for 5 mouthfuls and overflows 4 mouthfuls in mouth; Record thing tuple value G
1With cup tuple value G
2Dress water is till the spilling water in liquid spilled cup 3, and makes liquid spilled cup 3 overflow 4 mouthfuls of alignings of mouth to be subjected to liquid measure cup 5; Turn movable wheel shaft 10, testee 6 is slowly immersed in the water, make till liquid no longer flows out in the liquid spilled cup 3; Record buoyancy spring balance registration F
1With the heavy spring balance registration of liquid F
2Calculate buoyancy: F
Floating=G
1-F
1, liquid is heavy: G
Discharge opeing=F
2-G
2Experiment conclusion: the object that immerses in the liquid is subjected to buoyancy upwards, and the size of buoyancy equals the gravity that liquid that it arranges is subjected to, that is: F
Floating=G
Discharge opeing
