Utility model content
The technical problems to be solved in the utility model is for above deficiency, a kind of Physical Experiment iron ring of many diameters is provided, there is structure simple, easy and simple to handle, there is the circle body of multiple different-diameter, convenient during replacing different-diameter circle body, decrease the quantity of experiment equipment and the advantage of different experiments demand can be adapted to.
For solving above technical problem, the utility model by the following technical solutions:
A kind of Physical Experiment iron ring of many diameters, comprise iron staff, fixator and circle body, the quantity of described circle body is at least two and diameter is different, circle body is connected with two connecting rods, connecting rod by rotating shaft and iron staff hinged, the circle body diameter that the connecting rod nearer with iron staff distance is connected is less, and two rotating shaft symmetries are located on iron staff, and rotating shaft is provided with the fixed knob for fixed connecting rod;
One end of iron staff is connected with fixator, and rotating shaft is less than the length of connecting rod with the distance away from one end of the iron staff of fixator.
Below the further optimization to such scheme:
Described iron staff is inserted with support bar away from one end of fixator, and the one end near fixator on support bar is connected with pusher.
Described iron staff is provided with the groove coordinating pusher movement.
Described circle body is provided with the through hole for inserting support bar.
After the utility model adopts above technical scheme, compared with prior art, have the following advantages: the utility model apparatus structure is simple, easy and simple to handle; In an iron ring, be provided with the circle body of multiple different-diameter, decrease the quantity of experiment equipment, convenient during replacing different-diameter circle body, the demand of different experiments can be adapted to.
