Description
The present invention relates to a kind of electronic digit display dynamics meter regulator tool, such as electronic digit display type boxing machine, spring-grip and chest-developer.
The electronic digit display dynamics meter regulator tool has overcome the defective of simple mechanical formula dynamics meter regulator tool in the past, has advantages such as directly perceived, accurate.Existing electronic digit display dynamics meter regulator tool, the electronic digit display type force meter applied on September 15th, 88 of the applicant for example, application number 88214118.X, generally form by beaer (such as the boxing support), sensor (a kind of resistance strain gage) and electronic digital display device, because mechanically deform, the creep of sensing element, the temperature of electronic devices and components floats, the time influence of factor such as float, make this class force meter have problems such as null offset, during use, must often adjust the electronic circuit part.This not only increases the trouble that apparatus is safeguarded, and influences certainty of measurement.Existing electronic digit display type force meter also exists and can not upgrade, keep dynamics tidemark, the application of force number of times in can not record unit time and can not add up defective such as dynamics numerical value.
The objective of the invention is to overcome the above-mentioned defective of existing electronic digit display dynamics meter regulator tool, electronic digital display device is improved, adopt micro-computer technology, provide that a kind of function is complete, the micro-processor controlled electronic digit display dynamics meter regulator of good stability.
Feature of the present invention is to act on the power of beaer (such as boxing mechanism, grip mechanism, arm strength mechanism etc.), through sensor (a kind of resistance strain gage), be converted into the signal of telecommunication, send microsystem by electronic circuit, by the program that designs in advance, after various computings, send display, show various data, as dynamics, application of force number of times, dynamics peak, aggregate-value etc.
