Description
Technical field
Physics facility field is the utility model is related to, particularly a kind of single pendulum ball experiment instrument.
Background technology
Experiment with simple pendulum, can be to the mutual conversion between potential energy and kinetic energy as a part more important in Physical Experiment
Studied, but existing laboratory apparatus structure is relatively simple, not only the inclination of Rong Yinwei swing balls causes to miss research process
Difference, while also can not intuitively observe the travel track of swing ball.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of single pendulum ball experiment instrument, can ensure bead initial bit
That puts is accurate, avoid bead initial position and track not at grade caused by error, while also cause the traveling of bead
Track is more directly perceived, being capable of clearly observation experiment process more directly perceived for student.
In order to solve the above technical problems, technical scheme is used by the utility model：A kind of single pendulum ball experiment instrument, including
Support, support are provided with deep-slotted chip breaker, and circular orbit, the diameter of circular orbit and the diameter phase of deep-slotted chip breaker are fixed with deep-slotted chip breaker
Together, four corners of the top surface of support are provided with support, and support one end is fixedly installed on support by screw, and the other end extends to
Above circular orbit, two supports of the same side, which are located on one end above circular orbit, is fixed with same bearing bracket stand, axle
Bearing is provided with bolster, horizontal rotary shaft is provided between two bearings, swing rod one end is provided with rotation axis connection, the other end
Test ball.
In preferable scheme, multiple experiment balls are additionally provided with described circular orbit, swing rod connects with one of experiment ball
Connect.
In preferable scheme, described two end faces of support are provided with groove, and multiple dividing plates are provided with groove.
In preferable scheme, described rotary shaft is provided with the screwed hole of radial direction, and screwed hole is arranged on where circular orbit
In plane, swing rod and one end of rotation axis connection are provided with external screw thread, are threadedly coupled between swing rod and rotary shaft.
A kind of single pendulum ball experiment instrument provided by the utility model, by using said structure, has the advantages that：
（1）The vertical position positioning of experiment bead initial position is realized, guarantee realizes bead and hit bead positioned at same
On one vertical plane, the resultant error caused by not on same vertical plane is avoided；
（2）It can show the track of bead using circular orbit more clear directly perceived, it is real demonstrating single pendulum to student
It is that student can be perfectly clear it was observed that the movement locus of bead when testing.
