Description

Technical Field

[0001] The utility model relates to the technical field of table tennis serving machines, and more specifically to a table tennis serving machine with adjustable trajectory. Background Art

[0002] Automatic serving machines are widely used in modern table tennis, and are suitable for use in society, schools, families, and professional training venues. When using an automatic serving machine for training, the serving angle requirement is relatively high, so multiple serving angles are required. However, when the existing table tennis serving machines are used, their positions are usually fixed, resulting in a relatively single serving trajectory, which makes the training flexibility poor.

[0003] The utility model patent with patent announcement number CN219023183U discloses a serving adjustment mechanism for a table tennis serving robot. The advantage of this structure is that the mounting tube is fixedly connected to the serving machine through the mounting hole, and the table tennis ball enters the bellows through the goal hole and goes out of the ball outlet tube. When the serving angle needs to be changed, the rotating plate is rotated to adjust the deflection angle of the serving in the horizontal direction, and the threaded tube is rotated to make the threaded rod move up and down, thereby adjusting the vertical angle of the serving, so that the serving angle can be changed at a large angle.

[0004] However, in actual use, although the serving angle of the table tennis ball can be adjusted, the serving machine is prone to vibrate the mounting tube during the serving process, which can easily cause the mounting frame to shake on the ground, thus easily affecting the serving effect.
