Abstract

The invention belongs to the technical field of sports equipment, and particularly relates to an automatic ball launcher. The automatic ball launcher comprises a ball box, a corner bracket, a slappingboard, a French curve, a pressure stem, an angle pole and a hydraulic cylinder. One end of the angle pole is rotatably connected with an output shaft of the hydraulic cylinder, and the other end of the angle pole is fixedly connected with the pressure stem. The corner bracket is rotatably connected with the side wall of the ball box. The corner bracket comprises a first pole and a second pole, the free end of the first pole is connected to the inertial component which can allow the corner bracket to be rotated, the body of the second pole is slidably contacted with the free end of the cornerbracket. A C-shaped inner arc surface is arranged on the French curve, the inner arc surface is slidably contacted with the free end of the second pole, and the bottom of the French curve is fixedly connected with the slapping board. A pitching mouth is arranged on the top of the ball box, and an outlet is arranged at the bottom of the French curve. The slapping board is located below the outlet and rotatably connected with the bottom of the ball box. According to the technical scheme, the automatic ball launcher can increase the bouncing strength of the table tennis ball and reduce the invalid ball.

Description

technical field [0001] The invention belongs to the technical field of sports equipment, and in particular relates to an automatic ball-serving device. Background technique [0002] Table tennis is our national sport, and it is very popular in national sports, and athletes can achieve impressive results in international competitions and their usual training is inseparable. Athletes basically rely on two people to practice against each other in training. The strength of the two sides is different. Athletes with good skills may not be able to achieve the training effect they want, and the training time needs to be arranged by two people. Not free in time either. In order to solve this problem, people have invented table tennis ball machine, can utilize table tennis ball machine, realize single practice. [0003] The Chinese patent with the application number CN201520339689.0 discloses a simple table tennis ball serving device, including a table tennis table, a ball net is ar...
