Physical health test data collection device

Abstract

The invention discloses a physical health test data collection device which comprises a positioning frame, a shaft rod is mounted on the positioning frame, a plurality of shifting pieces are rotationally arranged on the shaft rod, each shifting piece is provided with a concave groove and a guide slope, a swing arm is arranged in each concave groove, and a plurality of guide slopes are arranged on the guide slopes. The swing arm on the lower layer of the shifting piece abuts against the guide slope of the upper layer of the shifting piece, and the guide slope is provided with a protruding part. When the driving force received by the shifting piece is larger than a preset value, the shifting piece drives the swing arm to cross the protruding part, and when the driving force received by the shifting piece is smaller than the preset value, the shifting piece drives the swing arm not to cross the protruding part and reset. The physical health test data collection device provided by the invention ensures that the unflapped plectrum is not interfered by friction force or vibration force generated by rotation of the flapped plectrum to generate relative displacement, and ensures smooth implementation of infrared detection signal butt joint detection.

Description

technical field [0001] The invention relates to the technical field of physical fitness monitoring, in particular to a physical fitness test data collection device. Background technique [0002] In order to ensure the healthy development of students' bodies, the school organizes students to undergo physical fitness tests every year. The items tested include ricochets, lung capacity, long-distance running, sprinting, pull-ups, and sitting and forward bending. Among them, the bounce test mainly utilizes a standing long jump tester or a height-feeling device. The height touch device mainly includes a support seat, a positioning frame, a rotating shaft, and multiple picks rotating on the rotating shaft. The height of the positioning frame is adjusted through the support seat. Students bounce and pat the picks, and determine the height by observing the moved picks. Students' ricochet ability. [0003] According to the patent number CN202120037617.6, the public (announcement) da...

Problems solved by technology

The above two assembly situations, no matter which one is suitable without exception, when the student's fingers can touch the highest-level plectrum and drive the plectrum to deflect, one or more plectrums on the upper floor will be affected by fluctuations. A certain angle of deflection occurs, so it is difficult to use electronic sensors to collect data on the paddle swing, and if you touch the sensor or pressure sensor on the paddle, this will increase the purchase cost of the entire touch height device; or To solve this problem by setting the fuzzy value through the program, the deflection angle of the pick due to the magnitude of the force generated by the slapped pick and the fluctuation during slapping is also unpredictable, which is obviously unrealistic
