Description
Technical field
It the utility model is related to technical field of teaching instruments, and in particular to a kind of physics teaching experiment instrument.
Background technology
Hooke's law, Hooke's law is once translated into, is a philosophy in mechanics elastic theory, is expressed as：Solid material
It is linear between the stress and strain (unit deformation amount) in material after expecting stress.In physical teaching course, pass through
The relation of rock spring elongation and counterweight pulling force is easy to student to understand.At present, experiment process is by being set on a spring
Different balancing weights is put, measures elongation, then carry out drawing making.
The synthesis of power can carry out observational measurement with decomposition by with the elongation of spring, lack energy in existing instruments used for education
It is enough to demonstrate the synthesis of power and the laboratory apparatus decomposed by Hooke's law.
Utility model content
The utility model is in order to solve the above technical problems, provide a kind of physics teaching experiment instrument.
Technical problem to be solved in the utility model is realized using following technical scheme.
A kind of physics teaching experiment instrument, including a pair of spaced apart vertical bars, the vertical bar bottom are fixed on bottom
On seat, vertical bar sets the first cross bar, the second cross bar, the 3rd cross bar respectively close to upper and lower end and centre position, and described first
Cross bar, the second cross bar are slidably secured in vertical bar, and disk, the disk is fixedly mounted in the second cross bar centre position
It is fixedly connected by rotating shaft with the second cross bar, the peripherally disposed angle coordinate of disk, the first dynamometer, the second dynamometer one
End is fixed in rotating shaft, and the other end is separately fixed on the first cross bar, and cloth is at an angle of between the first dynamometer, the second dynamometer
Put, the 3rd dynamometer one end is fixed in rotating shaft, and the other end is fixed on the 3rd cross bar.
First dynamometer, the second dynamometer, the 3rd dynamometer are made up of panel, spring respectively, are set on the panel
It is equipped with scale.
First dynamometer, the second dynamometer are connected by the sliding shoe being fixed on the first cross bar with the first cross bar.
The beneficial effects of the utility model are：By setting dynamometer and disk, the reading on dynamometer and disk is utilized
The size and Orientation of power is measured, so that passing through the laboratory apparatus with decomposing on the Hooke's law of spring and the synthesis of power
Demonstrated, the utility model is simple in construction, use, is suitable for classroom instruction use.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in figure 1, a kind of physics teaching experiment instrument, including a pair of spaced apart vertical bars 1, the bottom of vertical bar 1
It is fixed on base 2, vertical bar 1 sets the first cross bar 3, the second cross bar the 4, the 3rd respectively close to upper and lower end and centre position
Cross bar 5, the first cross bar 3, the second cross bar 4 are slidably secured in vertical bar 1, and peace is fixed in the centre position of the second cross bar 4
Disk 9 is filled, disk 9 is fixedly connected by rotating shaft 12 with the second cross bar 4, the peripherally disposed angle coordinate 10 of disk 9, and first

It is provided with scale, the sliding shoe 11 and first of the first dynamometer 13, the second dynamometer 14 preferably by being fixed on the first cross bar 3
Cross bar connects.
Using this laboratory apparatus when, first by sliding block 11 slide into it is spaced apart make the first dynamometer 13, second survey
Power meter 14 is at an angle, then the first cross bar 3 is fixed in vertical bar 1 at a certain height, and the second cross bar 4 is along vertical bar 1
Eventually stablize during slip in vertical bar 1 at a certain height, finally by between the first dynamometer 13, the second dynamometer 14
The lengthening variable of three dynamometer springs of angle one-level goes out the size of each dynamometry dynamometric and making a concerted effort always.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
