High-precision hanging wheel for multifunctional test

Abstract

The present invention discloses a high-precision hanging wheel for the multifunctional test. The high-precision hanging wheel comprises a cross beam I. The lower surface of the cross beam I is provided with a sensor. A fixed shaft is arranged below the cross beam I. The middle part of the fixed shaft is provided with a hanging wheel. A light reflecting plate is pasted on the hanging wheel. The left and right ends of the cross beam I are provided with a cross beam supporting sheet. The cross beam supporting sheet is provided with an iron chain. The front surface of the cross beam supporting sheet is provided with a signal output port. The right side of the cross beam supporting sheet is provided with a signal processing box. The cross beam I and a cross beam II are arranged to match with the cross beam supporting sheet, so that the fixed shaft and the hanging wheel are fixed. Meanwhile, the sensor and the light reflecting plate are arranged to match with the signal processing box, so that the rotation circle number of the hanging wheel can be recorded. Furthermore, the data of the hanging wheel are ensured to be accurate and error-free. At the same time, the iron chain is arranged, so that the cross beam supporting sheet can be vertically separated. The data collection is not influenced at all. Moreover, the data measurement for various types of hanging wheels is facilitated. As a result, the high-precision hanging wheel is reasonable in structure, strong in practicability and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of teaching tools and suspension wheel experiments, in particular to a high-precision multifunctional test suspension wheel. Background technique [0002] In physics class, especially when it comes to mechanics, boring and empty theoretical teaching often makes students feel more and more boring, and gradually loses interest in learning. Single, a class often needs to carry a lot of equipment, and these teaching equipment are just simple work, there is no obvious intuitive data, a single rotation, and then rotate to finally stun the students. In the laboratory, when measuring the service life of the suspension wheel and the number of rotations of the suspension wheel , it often requires a lot of supporting equipment to measure the value, which is time-consuming and labor-intensive and has large errors. Therefore, an obvious and intuitive hanging wheel experimental device with small errors needs to be develop...
