Problems solved by technology

[0002] The external ball feeding and swing speed monitoring device of the table tennis ball is tested by hanging the test ball. During the process of the player swinging and hitting the test ball, the racket is monitored by two infrared emitters. The racket passes through two infrared emitters. The time end of the sensor is divided by the distance between the two infrared emitters to get the swing speed. However, in the prior art, the average level of the players is monitored by multiple swings in the test, but the ball is difficult to reset after the impact, and often swings indefinitely. The phenomenon affects the continuous test. At the same time, due to the pulling effect of the pull rope, the trajectory of the player's hitting the ball cannot be observed, so it is impossible to monitor the swing speed of different types of hitting

Abstract

The invention relates to the field of table tennis training devices, in particular to an external ball-down type table tennis ball supply and swing speed monitoring device, comprising a support frame, a support platform is fixedly installed on the front end surface of the support platform, and a support platform is fixed on the upper end surface of the support platform. A support column is provided, and the lower end of the support column extends a snap-in ball that is movably embedded in the upper end surface of the support platform. Two infrared emitters are arranged on the upper end surface of the support platform near the support column. A limit rod is extended from the lower end surface, and a reset soft ring is fixedly inserted around the inner side of the support platform corresponding to the limit rod, and the upper end of the snap-in ball is fixedly connected with a connection shell, and a magnet is arranged on the inside of the connection shell The upper end of the support frame is fixedly connected with a support plate extending forward. The present invention facilitates fast multi-group swing testing, and can perform ball trajectory testing to test swing speeds of different hitting types.
