Table tennis training device

Abstract

The invention provides a table tennis training device which effectively solves the problems that an existing pitching machine cannot pitch high-speed rotating balls and the track rotating speed of thetable tennis balls is not easy to control. According to the invention, the table tennis training device comprises a rectangular shell, a vertical plate is arranged in the shell, a U-shaped plate is fixed on the right side surface of the vertical plate, and the table tennis balls are placed in the U-shaped plate; big gears are arranged on front and rear side plates of the U-shaped plate, a rotating shaft is arranged in the U-shaped plate, a pinion is arranged at the end part of the rotating shaft, a first spline cylinder is fixed on one side, far away from the table tennis balls, of each big gear, rectangular boxes are arranged on front and rear sides of the U-shaped plate, first bevel gears are arranged in the rectangular boxes, and second bevel gears are arranged on left side plates; a first spline shaft capable of sliding in the axial direction of the first spline cylinder is inserted into the first spline cylinder, clamping plates are fixed to the end, close to the table tennis ball, of the first spline shaft, a pressure spring is installed between each clamping plate and the large gear, and the two clamping plates can clamp the table tennis balls under the action of the pressure springs; a hole is formed in a right side plate of the shell, and the table tennis balls can penetrate through the hole.

Description

technical field [0001] The invention relates to the technical field of sports training, in particular to a table tennis training device. Background technique [0002] Spinning is the most difficult, complex and difficult style of play. All athletes hope to master the way of playing and catching this kind of ball. At present, most of the serving machines used on the market are double-roller serving machines, and its core components are two rollers whose interval is slightly larger than the diameter of table tennis balls or table tennis balls. When working, the two rollers rotate counterclockwise at high speed. When the ping-pong ball passes through the gap between the two rollers, it will generate friction with the surface of the rollers due to pressure, and will be released from the ball-serving mechanism under the action of the friction. This design structure is simple, and if the rotational speeds of the two rollers are controlled to be different, the top spin or the bott...
