Abstract
The utility model discloses a simple pendulum device comprising a fixed plate, a spindle (7), a marline (5) and a small ball (3), wherein the entire fixed plate is set as a magnet plate (1); the bottom of the small ball (3) is connected and provided with a pointer (2); the spindle (7) is arranged on the top end of a centre shaft (6) of the magnet plate (1); 2 to 5 arc grooves (4) are uniformly arranged on the middle and lower section of the centre shaft (6); and the top end of the magnet plate (1) is also provided with a counter (8) which is connected with the spindle (7). The simple pendulum device can be fixed on a blackboard through the magnet plate to provide convenience for students of the whole class to observe. The simple pendulum device can accurately indicate the amplitude of swing of the small ball and indicates the frequency of swing of the small ball so as to help the students for comprehensive longitudinal and horizontal comparisons, thus being convenient for showing the classroom teaching effect.
Description
Technical field
The utility model relates to the technical field of a kind of physics classroom instruction with teaching aid, is specifically related to a kind of simple pendulum device.
Background technology
When demonstrating experiment with simple pendulum to the student; Generally be that single pendulum is fixed on the iron stand; Again iron stand is placed on the lectern, but such demonstration and inconvenient, because the presentation process that the limited feasible classmate who is sitting in the back of the height of lectern is difficult for seeing whole single pendulum.
The Chinese patent publication number is CN201927242U, and the utility model instructions that open day is on August 10th, 2011 discloses " a kind of simple pendulum device of carry magnet ", and this utility model comprises fixed head, back up pad, tumbler, rope, bead and magnet piece; Said fixed head comprises two faces; Be respectively front and back; Be fixedly connected between the front of said back up pad and fixed head, said tumbler pass back up pad and and back up pad between be rotationally connected, an end of said rope is fixed on the tumbler; The other end of said rope links to each other with bead, and said magnet piece is fixed on the back side of fixed head.But this utility model demonstration effect is still comparatively single, and amplitude effect that can not the swing of real time demonstration single pendulum can't show the frequency of single pendulum swing in addition.
The utility model content
The purpose of the utility model is to deficiencies such as the demonstration effect are single in the prior art, classroom teaching effect is limited, and a kind of simple pendulum device that effect is various, can show single pendulum amplitude of fluctuation, demonstration single pendulum frequency of demonstrating is provided.
The purpose of the utility model realizes through following technological means: a kind of simple pendulum device, include fixed head, rotating shaft, marline, bead, and described fixed head integral body is set to magnet plate; The bottom of described bead also is connected with pointer; Described rotating shaft is arranged on the top of the axis of magnet plate, also evenly is provided with 2-5 bar arc groove on the middle hypomere of said axis.
The top of said magnet plate also is provided with the counter that is connected with rotating shaft.
Also be provided with Winder in the described rotating shaft.
Compared with prior art the utlity model has following tangible advantage: this simple pendulum device can be fixed on the blackboard through magnet plate, and the classmate of whole class can both conveniently be observed.This simple pendulum device can be indicated the amplitude of bead swing accurately, shows the frequency of bead swing in real time, make classmates can be vertically, walk crosswise comprehensive comparison, convenient demonstration classroom teaching effect.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure, 1-magnet plate, 2-pointer, 3-bead, 4-arc groove, 5-marline, 6-axis, 7-rotating shaft, 8-counter.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is done further to describe in detail:
A kind of simple pendulum device as shown in Figure 1 includes fixed head, rotating shaft 7, marline 5, bead 3, and described fixed head integral body is set to magnet plate 1; The bottom of described bead 3 also is connected with pointer 2; Described rotating shaft 7 is arranged on the top of the axis 6 of magnet plate 1, also evenly is provided with 2-5 bar arc groove 4 on the middle hypomere of said axis 6.Be provided with like this, this simple pendulum device can be fixed in any position of blackboard easily through magnet plate 1, makes things convenient for the classmate's multi-angle in the classroom to observe.Can pass through the positions of pointer 2 accurate demonstration beads 3 swings on the bead 3, through arc groove 4, and the convenient amplitude of demonstrating bead 3 swings of the scale mark of top setting, comprehensive multiple demonstration effect improves the class demonstration effect.
The top of said magnet plate 1 also is provided with the counter 8 that is connected with rotating shaft 7.Be provided with like this, can make things convenient for the hunting frequency of real-time statistics bead 3.
Also be provided with Winder in the described rotating shaft 7.Be provided with like this, can control the length of marline 5, according to the needs of classroom instruction, demonstration flexibly.
In a word, the utility model provides a kind of simple pendulum device that effect is various, can show single pendulum amplitude of fluctuation, demonstration single pendulum frequency of demonstrating.The above; Be merely a part of embodiment of the utility model; The protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
Claims (3)
