Photoelectricity arc loop pingpong trainer

Abstract

The invention discloses a photoelectricity arc loop pingpong trainer comprising a pingpong bat (20), a photoelectricity switch group (30), a DC solid relay (4), power supplies (9) and (10), a pulse meter (5) and two groups of electrodes (15) and (16) thereof, wherein the photoelectricity switch group (30) is arranged on a bat surface (21) near a bat handle (22) by a support (50), and all photoelectricity switches are connected in parallel. When light rays emitted by any one photoelectricity switch are shielded by a pingpong, a corresponding photoelectricity switch sends out an electrical signal; then the electrical signal acts on the input end of the DC solid relay, thereby conducting the output end of the DC solid relay; the pulse meter (5) is turned on, and then the pulse meter (5) outputs pulse current by the two groups of electrodes (15) and (16). A correct conditioned reflex is formed by accurate timing muscle excitation contraction so as to help an arc loop pingpong learner master the skills of increasing the static friction time when the arc loop pingpong learner directly loses scores because of not being good at receiving the pingpong thrown by the counterpart and instantaneously increasing the angular acceleration after the pingpong touches the bat.

Description

technical field [0001] The invention relates to sports training equipment, in particular to table tennis auxiliary training equipment. Background technique [0002] Loop ball is one of the most basic and important techniques in table tennis competition. It relies on the friction between the table tennis ball and the rubber on the racket surface, causing the table tennis ball to spin forward at high speed. The key to learning loop ball well is to increase the static friction time of the table tennis ball on the racket after it touches the racket, and quickly retract the forearm to exert explosive force to make the table tennis ball generate angular acceleration and throw the ball out. But for the loop ball beginners, when training the loop ball, either the static friction time of the table tennis ball on the racket after touching the racket is short, and the loop ball cannot be formed; The looper doesn't work well. Therefore, in order to pull out high-quality loop balls, it...
