Embodiment Construction

[0018] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0019] combine Figure 1-5 , The tennis exercise machine includes an exercise frame 1, a launch mechanism 2, a horizontal rotation mechanism 3, a gear 4, a gear 5, a motor 6, a motor 7, and wheels 8. Wheel 8 is under the exercise frame 1, and is driven by a motor to realize the movement of the horizontal position. The tennis ball is accelerated and launched in launch mechanism 2. The adjustment of the launch position is mainly realized by the motor driving the gear.

[0020] The launch mechanism 2 is placed in the horizontal rotation mechanism 3, and the gear 2 5 is driven by the motor 2 6 to realize its rotation around the axis of rotation, thereby realizing the adjustment of the vertical launch angle. The motor one 7 drives the gear one 4 transmission so as to realize that the horizontal rotation mechanism 3 rotates around the frame, and realizes the adjustme...

Abstract

The invention aims at providing a tennis trainer which comprises a trainer rack, a launching mechanism and a horizontally-rotating mechanism. The tennis trainer is characterized in that the launching mechanism is fixed in the horizontally-rotating mechanism, and the trainer rack is positioned outside the horizontally-rotating mechanism and is connected with the horizontally-rotating mechanism. The tennis trainer has the characteristics of undemanding air pressure for tennis launching and high launching accuracy, and can realize the self rotation of the tennis and vividly simulation on playingtennis by human. Besides, the tennis trainer has the advantages of simple structure, lighter weight, high safety performance and lower overall cost.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a mechanical device used in the field of physical training.
