Abstract
The utility model discloses a simple pendulum demonstrator, which mainly comprises a balance base, a metal long straight bar, a flat panel, a horizontal cross bar, a veneer noose and a photoelectric timer. The metal long straight bar is fixed on the balance base and the horizontal cross bar is fixed to the top of the metal long straight bar. The flat panel is fixed at the intermediate part of the metal long straight bar. The photoelectric timer is fixedly arranged at the lower part of the flat panel. The veneer noose is composed of a smooth circular ring, a rigid light rope and a small metal ball. The simple pendulum teaching demonstrator is simple in design, convenient, practical and the like.
Description
Technical field
The utility model relates to a kind of demonstration instrument for teaching, relates in particular to a kind of single pendulum demonstration instrument for teaching.
Background technology
Measure the number of times of single pendulum swing and easily make mistakes in the instruments used for education of measuring period of single pendulum, so just the calculating of period of single pendulum caused impact, experimental data can not get real value.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to propose a kind of single pendulum demonstration instrument for teaching, this instruments used for education can accurately be write down bead by the number of times of minimum point by photoelectricity door timer, the cycle that so just can provide information help accurately to calculate single pendulum.
To achieve these goals, the technical solution adopted in the utility model is such: it mainly is comprised of balance base, the long straight-bar of metal, flat board, horizontal cross bar, veneer rope sling and photoelectricity door timer; The long straight-bar of metal is fixed on the balance base, and horizontal cross bar is fixed on the top of the long straight-bar of metal, and flat board is fixed on the centre of the long straight-bar of metal, is fixed with photoelectricity door timer below flat board; The veneer rope sling is gently restricted by smooth torus, rigidity and prill forms.
Useful technique effect of the present utility model is: prill is fixed on smooth torus by the light rope of rigidity, utilizes the less friction force of smooth torus and horizontal cross bar to reach bead and do undamped oscillation; Utilize photoelectricity door timer to write down bead by the number of times of minimum point; Utilize scale on flat board to read the pendulum length of single pendulum, then calculate the cycle of single pendulum.
Description of drawings
Fig. 1 is schematic perspective view of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Structure of the present utility model is: it mainly is comprised of balance base (1), the long straight-bar of metal (2), dull and stereotyped (3), horizontal cross bar (4), veneer rope sling (5) and photoelectricity door timer (6); The long straight-bar of metal (2) is fixed on balance base (1), and horizontal cross bar (4) is fixed on the top of the long straight-bar of metal (2), and dull and stereotyped (3) are fixed on the centre of the long straight-bar of metal (2), is fixed with photoelectricity door timer (6) in the below of dull and stereotyped (3); Veneer rope sling (5) is gently restricted (52) by smooth torus (51), rigidity and prill (53) forms.
At first the utility model is placed on this device on horizontal table top when in use, the smooth torus (51) of veneer rope sling (5) is injected on horizontal cross bar (4), open prill (53) is pulled away from after photoelectricity door timer (6) minimum point allow rigidity gently restrict (52) parallel with dull and stereotyped (3), then static release gets final product, the time of writing down the bead motion just can calculate the cycle of single pendulum with the number of times of reading photoelectricity door timer (6), and this device is convenient and practical.
