detailed description

The specific embodiments of the present utility model will be described in detail below in conjunction with accompanying drawings 1-4, but it should be understood that the protection scope of the present utility model is not limited by the specific embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

A tennis practice device provided by the utility model, as shown in FIG. The rod 3 is connected, and the vertical plate 2 is horizontally provided with a first chute 2-1 and a support plate 8, and the support plate 8 is perpendicular to the vertical plate 2 and is arranged on the side of the first chute 2-1. Below, the first chute 2-1 is provided with a first roller 5, the back of the ball box 4 is connected with the first roller 5, the ball box 4 is provided with a motor, and the ball box 4 is provided with a motor. A roller 5 is connected with the motor shaft, and the motor is connected with the signal of the microprocessor through the motor controller, and both the motor and the microprocessor are electrically connected with the power supply. As shown in Figure 2, a second chute 8-1 is horizontally provided on the support plate 8, and a second roller is arranged in the second chute 8-1, and the lower end of the goal box 4 and the second Roller connection, the front and lower openings of the goal box 4, the back is provided with mesh cloth 4-1, the lower opening is provided with a net pocket 6, the other end of the net pocket 6 is connected with a slide rail 7, the slide rail 7 It is arranged on the riser 2 and is located below the goal box 4 . As shown in FIG. 3 , the slide rail 7 includes a downwardly inclined track 7-1, an arcuate track 7-2 and an upwardly inclined track 7-3 connected in sequence. Wherein, the motor can be a stepping motor, the microprocessor can be a PLC controller, and the model of the microprocessor is ARMSTM32F.

When using this tennis practice device, the numerical value is set in advance by the microprocessor, and when the motor rotates and reaches the set numerical value, that is, the first roller 5 advances to a certain distance in the first chute 2-1, and the motor reverses Rotate, continue to travel the set distance, the motor then rotates forward, and so on. The second chute 8-1 on the support plate 8 realizes the supporting effect on the ball box 4 through the second roller. In this way, the goal box 4 moves left and right under the drive of the motor, and the tennis ball entering the goal box 4 enters the slide rail 7 under the guidance of the net bag 6, and the tennis ball produces a speed in the slide rail 7, which is inclined from the upwardly inclined track 7-3. Throw it out, and the practitioner can swing the racket to hit the tennis ball. During tennis practice, the number of times of entering the goal box 4 can be used as the practice score. Successfully entering goal box 4 is an excellent result, which encourages practitioners to improve their playing skills and make continuous progress. Also can allow goal box 4 to be fixed according to actual needs, allow the practitioner to practice a certain action repeatedly.

Further, the width of the slide rail 7 is larger than the diameter of the tennis ball, so that the tennis ball can roll down therefrom.
