Description
Technical field
The utility model belongs to teaching experimental equipment field, particularly a kind of Archimedes principle test unit for junior middle school physics teaching experiment.
Background technology
In grade eight physics Archimedes principle of existing junior middle school one joint, experimental technique is tested and introduced to the size that requires student to carry out buoyancy with the relation that arranges the suffered gravity of liquid, but the inadequate specific, concrete of its institute's experimental provision of introducing, experimentation is comparatively complicated, in experiment, lack intuitive, and can not once complete.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of existing experimental provision, provides a kind of simple in structure, easy and simple to handle, intuitive strong, interesting strong, safe Archimedes principle test unit.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of Archimedes principle test unit, it is characterized in that: by installing plate, large support, hook-type crossbearer, spring balance, float, liquid header, small rack, annular crossbearer, spilling water cup forms, large support is installed in a side above installing plate, hook-type crossbearer is installed in a large top of the trellis, spring balance is suspended on hook-type crossbearer, float hangs on liquid header internal upper part, float, liquid header is suspended on spring balance jointly, small rack is relatively arranged on opposite side above installing plate with large support, annular crossbearer one end is movably set in small rack top, the annular crossbearer other end stretches into float below in liquid header, spilling water cup is installed on one end relative with small rack on annular crossbearer.
And, described liquid header, its middle part, side is open shape.
Advantage of the present utility model and beneficial effect are:
1. this Archimedes principle test unit is simple in structure, makes, installs easily.
2. the size of this Archimedes principle test unit experiment buoyancy equals suffered disposable the completing of gravity of liquid that it arranges, and easy and simple to handle, intuitive is strong, interesting strong.
3. this Archimedes principle test unit scientific structure design is reasonable, have simple in structure, fabrication and installation easily, test disposablely complete, easy and simple to handle, intuitive strong, the interesting advantage such as strong, is a kind of Archimedes principle test unit with higher innovation.
Accompanying drawing explanation
Fig. 1 is demonstration schematic diagram of the present utility model.
1-small rack, 2-annular crossbearer, 3-hook-type crossbearer, 4-spring balance, the large support of 5-, 6-float, 7-spilling water cup, 8-liquid header, 9-installing plate.
Embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
An Archimedes principle test unit, is comprised of installing plate 9, large support 5, hook-type crossbearer 3, spring balance 4, float 6, liquid header 8, small rack 1, annular crossbearer 2, spilling water cup 7.Large support is installed in a side above installing plate, hook-type crossbearer is installed in a large top of the trellis, and spring balance is suspended on hook-type crossbearer, and float is the little plastic bottle of filling water, float hangs on liquid header internal upper part, and float, liquid header are suspended on spring balance jointly; Liquid header is an inversion beverage bottle, and its middle part, side is open shape.Small rack is relatively arranged on opposite side above installing plate with large support, annular crossbearer one end is movably set in small rack top, the annular crossbearer other end is made annular shape, and float below in liquid header is stretched in annular shape one end, and spilling water cup is installed in annular crossbearer pressed on ring shape snap ring.
Principle of work of the present utility model is:
The utility model Archimedes principle test unit using method:
1, before experiment, spilling water cup outer wall and float outer wall are soaked by same liquid, spilling water cup outer wall and float outer wall are stained with the error of extension liquid formation when eliminating liquid spill;
2, spring balance, liquid header, float are suspended on hook-type crossbearer successively;
3, will in spilling water cup, fill with liquid as water and be installed on annular crossbearer;
4, observe spring balance weight (weight is now the weight of float, liquid header) now;
5, the annular crossbearer being movably set on small rack is upwards slowly moved, make float slowly immerse certain depth in spilling water cup, now, float is subject to buoyancy and the liquid in spilling water cup is discharged in inflow liquid header in spilling water cup, observe spring balance, weight is constant.
In float slowly immerses spilling water cup, when float is subject to buoyancy, weight should alleviate, but the liquid of discharging due to float is again in influent gatherer, and weight do not change, and illustrates that the size of buoyancy equals the suffered gravity of liquid that it arranges.
6, annular crossbearer is continued to move up, the degree of depth that float immerses spilling water cup is strengthened, discharge more water, now, observe spring balance, weight is still constant.
By this experiment, the size that can make student understand deeply, intuitively buoyancy is followed the relation that arranges the suffered gravity of liquid, and the size of buoyancy of object equals the suffered gravity of liquid that it arranges.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: within not departing from the spirit and scope of the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
