Description
Technical field
This utility model is related to a kind of experimental facilitiess, is specifically a kind of for demonstrating simple harmonic motion, belongs to field.
Background technology
Single pendulum is primary school, the conventional standing experiment equipment that junior middle school imparts knowledge to students；Mainly by pendulum, line（Pendulum length）, fixing line dress
Put composition；Tape measuring pendulum length is used during experiment first, then with manual time-keeping and people's number number of oscillations obtaining calculating data,
Pendulum length, the impact of the number of times of pendulum weight and pivot angle to putting are studied by these data.Existing product exist defect be：Adjust pendulum
It is long inconvenient, and pendulum length is intended to remeasure pendulum length with chi after adjusting every time, is very much trouble.Swing ball is typically all a ball,
Weight can not change.Due to being manually to pinch manual time-keeping, it seem likely that there are human users, experimental result error compared with
Greatly.
Utility model content
The technical problem solved by this utility model is to provide that a kind of parameter measurement is accurate, experiment parameter is easy to adjust
Simple harmonic motion Rule device.
This utility model patent is achieved through the following technical solutions：
A kind of characteristics of motion tester of single pendulum, including column, are fixed on the single pendulum support of column top, stand on single pendulum
Photogate below frame and the pendulum on single pendulum support, the detection light path of photogate and the swing rail of pendulum are suspended on by swing rope
Mark intersects, and also includes that, for showing the graduated disc of pendulum rocking tendency, graduated disc is fixed under single pendulum support by lifting support
On the column of side, one is provided with the central point of 0 ° of graduation mark of graduated disc and swing rope can be fixed swing rope fixing hole therein.Will
The suspension point of cycloid is fixed on the central point of 0 ° of graduation mark of graduated disc, so no matter extends or shrinks cycloid, as long as upper downward
Whole lifting support can be completed, and during whole regulation, the lowest point of bob motion track is consistent all the time constant,
As long as this cleverly designs can also ensure that photogate and the position of pendulum correct accurate for the first time, subsequently no matter how real
Testing all need not carry out secondary correction.
Further, lift the swing rope that fixed support is provided with the column card interface and single pendulum support connected and fixed with column
The front swing rope fixing hole of the rear swing rope fixing hole and fixed pendulum end swing rope of end homonymy is put, this is to ensure that cycloid is adjusted
Accuracy, the minimum point of pendulum swinging track are intersected with the detection light path of photogate, in fact namely pendulum transfixion when its
Location is intersected with the light path of photogate, is alignd with photogate measurement zone.
Further, one section of guiding flexible pipe is socketed with the swing rope between rear swing rope fixing hole and front swing rope fixing hole,
This is smooth when adjusting pendulum length in order to ensure.
Further, it is oriented to flexible pipe and runs through rear swing rope fixing hole and front swing rope fixing hole.
Further, pendulum includes a basic hammer body and the weightening hammer body that can be socketed in successively on the basic hammer body.
Further, to state and a circle groove is respectively equipped with basic hammer body and weightening hammer body hammer, the position of the groove is high
Degree is consistent with the respective height of C.G. of basic hammer body, weightening hammer body, and the length of single pendulum is the origin put to pendulum upper groove
Air line distance.
The beneficial effects of the utility model are：Have the advantage that compared with prior art：
1. pendulum length is easy to adjust：By adjustment dial group highly changing pendulum length, it is only necessary to which a step can just be completed, and
And pendulum highly keeps constant.
2. pendulum weight-adjustable：As weightening hammer body quality, weightening hammer body can be enclosed within basic hammer body basic hammer body
Use, quality doubles, and particle position is constant.
3. graduated disc can school zero graduation line.
4. sensor measurement accuracy rate is higher, easy to use.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Structural representations of the Fig. 2 for pendulum；
In figure：Iron stand column 1, photoelectricity door bracket 2, photogate 3, pendulum 4, graduated disc 5, swing rope and iron stand fixing end
6, tetrafluoro flexible pipe 7, basic hammer body 4.1, increase weight hammer body 4.2.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that this utility model is realized are apparent to, in conjunction with
Accompanying drawing is expanded on further how this utility model patent is implemented：
The characteristics of motion tester of a kind of single pendulum, as shown in figure 1, swing rope is fixed on iron stand with iron stand fixing end 6 standing
The top of post 1, photogate 3 are fixed on iron stand bottom by photoelectricity door bracket 2, with iron stand column in the middle of lifting fixed support
1 fixes, and lifts support bracket fastened rear swing rope fixing hole and swing rope and 6 homonymy of iron stand fixing end, and front swing rope fixing hole is passed through to be carved
The central point of 0 ° of graduation mark of scale, tetrafluoro flexible pipe 7 run through rear swing rope fixing hole and front swing rope fixing hole, and swing rope is soft through tetrafluoro
The photogate on iron stand is hung down to after pipe 7.
The structure of hammer body 4, as shown in Fig. 2 a circle groove is respectively equipped with basic hammer body 4.1 and the weightening hammer of hammer body 4.2,
The center of gravity of basic hammer body 4.1 and weightening hammer body 4.2 be through well-designed, the position height of groove be based on hammer body 4.1,
