Description

Technical Field

[0001] The utility model relates to the technical field of sports auxiliary training, in particular to a table tennis serving machine. Background Art

[0002] Table tennis ball machine is an essential entertainment and training tool suitable for use in society, schools, families and professional training venues.

[0003] Publication number CN 111481908 A discloses a ball-serving machine comprising a launch tube and a ball-serving assembly. The launch tube has an outlet angled upward. The assembly includes a ball-serving device, an elastic member, a swing arm, and a ball-serving actuator for rotating the swing arm. The middle portion of the ball-serving device is rotatably mounted at the rear end of the launch tube. The front portion of the ball-serving device serves as the ball-serving unit, and the swing arm's rear upper side surface provides force. In this ball-serving machine, ping-pong balls drop from the top opening of the ball-serving device into an internal channel, which connects to the channel at a 90-degree angle. During use, multiple balls are typically stored at the opening and arranged to fall into the channel. Consequently, balls at the opening squeeze balls within the channel. When the swing arm applies force to the balls in the channel, the balls within the channel may become stuck with the balls at the opening, preventing the balls from being launched.

[0004] Therefore, the structure of the ball machine needs to be further optimized. Utility Model Content

[0030] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] See also Figures 1-8 , a table tennis serving machine, comprising a casing 1, a ball outlet assembly and two ball shooting shells 6, the casing 1 is provided with a ball bin 2 inside and an opening 3 on the top, the ball bin 2 is communicated with the opening 3; the ball outlet assembly comprises a screw 4 and a first rotating driving member, the screw 4 is arranged in the ball bin 2, the screw 4 and the two side walls of the casing 1 form a accommodating bin 5 for accommodating table tennis balls, the first rotating driving member is arranged on the casing 1, and the first rotating driving member is connected to the screw 4; the ball shooting shell 6 is movably connected to the casing 1, the ball shooting shell 6 is provided with a ball shooting hole 7 and a ball shooting member, and the two ball shooting holes 7 correspond to the two accommodating bins 5 respectively.

[0032] The working principle of the above technical solution is as follows: the table tennis ball enters the ball bin 2 from the opening 3 of the casing 1 and falls into the receiving bins 5 on both sides of the screw 4. The first rotary drive member is started to rotate the screw 4, and the screw 4 pushes the table tennis balls in the receiving bins 5 on both sides into the ball shooting shell 6. The ball shooting member applies force to the table tennis ball to shoot it out.

[0033] To supplementally explain, the first rotation driving member is a motor.

[0034] In this embodiment, the housing 1 is provided with an extension bar 9, which is arranged perpendicular to the side of the housing 1. The extension bar 9 is provided with two rows of first retaining holes 10, which are arranged in an arc shape on both sides of the housing 1. The ball-shooting shell 6 is provided with first protruding retaining holes 11, and the two ball-shooting shells 6 are respectively retained in the two rows of first retaining holes 10 via the first protruding retaining holes 11. Manually moving the ball-shooting shell 6 toward the sides of the housing 1 and rotating it outward, the first protruding retaining holes 11 will fall into the corresponding first retaining holes 10, at which point the angle of the opening 3 of the ball-shooting shell 6 will shift to the sides, thereby adjusting the direction of ball discharge. The use of retaining holes and retaining holes to achieve angle adjustment of the ball outlet provides a simple structure and facilitates adjustment.

[0035] In addition, the distance between the front bottom of the housing 1 and the extension strip 9 is adapted to the height of the ball shell 6, and the ball shell 6 is just stuck between the front bottom of the housing 1 and the extension strip 9. The surface of the first protruding position 11 is an arc surface.

[0036] In this embodiment, the ball-shooting element includes a ball-shooting wheel 8 and a second rotary drive element.
