DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] The present utility model provides an adjustable table tennis practice device as shown in Figure 1 - Figure 5 Figure, which includes a table tennis table 1 and an automatic ball feeder 2. The automatic ball feeder 2 is arranged on one side of the table tennis table 1. The automatic ball feeder 2 is a device for automatically launching table tennis balls. It combines a mechanical structure, an electronic control system, and specific functional designs. Self-locking universal wheels 505 are equidistantly arranged at the bottom of the automatic ball feeder 2, which can move the device and increase the flexibility of the device.
[0022] An adjustment component for changing the trajectory of the table tennis ball is arranged at the output end 3 of the automatic ball feeder 2. Mainly during the ball serving process, by driving the amplitude of the front end rotating tube 403, the table tennis ball can be launched in an arc trajectory, changing the flight path of the table tennis ball. This not only increases the difficulty of serving by the ball feeder but also provides a variety of practice modes for the practitioner. The practitioner can experience a more complex scenario closer to actual combat because the ball path of the arc trajectory is more difficult to predict and respond to. By adjusting the amplitude of the rotating tube 403, the ball feeder can simulate serves at different angles and arcs, enabling the practitioner to gradually adapt and improve the ability to handle various ball paths during training.
[0023] The adjustment component includes a first support plate 401, which is fixedly arranged at the output end 3 of the automatic ball feeder 2. A rotating shaft 402 is rotatably arranged on the surface of the first support plate 401. One end of the rotating shaft 402 is fixedly provided with a rotating tube 403. A second support plate 404 is fixedly arranged at the output end 3 of the automatic ball feeder 2. A motor 405 is fixedly arranged on the second support plate 404. A driven gear 406 is fixedly arranged on the outer side wall of the rotating shaft 402. A driving gear 407 is fixedly arranged at the output end of the motor 405. The driving gear 407 is meshed and connected with the driven gear 406.
[0024] When the trajectory of the serve needs to be adjusted, the output end of the motor 405 drives the rotating shaft 402 to rotate by driving the motor 405 to rotate. As the rotating shaft 402 rotates, the driving gear 407 is driven to rotate. The driving gear 407 rotates and drives the driven gear 406 to rotate. The driven gear 406 rotates with the rotating shaft 402, and the rotating cylinder also rotates synchronously. When the output end 3 of the automatic serving machine 2 launches the table tennis ball, the table tennis ball contacts the inner wall of the rotating cylinder. Due to the rotation of the rotating cylinder, the table tennis ball contacts the inner wall and is launched along the arc of the inner wall, thereby realizing the steering of the table tennis ball after launching.
[0025] By controlling the different directions of the output end 3 of the motor 405, the rotation amplitude of the rotating cylinder can be adjusted, thereby realizing diversified adjustments to the trajectory of the table tennis ball launch. This flexible control method not only increases the functionality and fun of the ball serving machine, but also provides practitioners with more diverse practice modes, which helps them simulate more complex scenes in actual combat during training and improve their ability to cope with various ball paths.
[0026] Considering that after launching the ping-pong ball, the table tennis practitioner needs to pick up the ping-pong ball from the ground and put it into the table tennis training machine, which is rather troublesome, an automatic recovery component for recovering the ping-pong ball is arranged on the surface of the table tennis table 1, the purpose of which is to effectively intercept the ping-pong balls launched from the front and the left and right sides. The intercepted ping-pong balls will automatically accumulate at the input end 6 of the automatic ball serving machine 2, thus realizing the automatic recovery and reuse of the ping-pong balls. This not only saves the trainee the tedious steps of manually picking up the balls and reloading them into the ball serving machine, but also greatly improves the continuity and fluency of the training, allowing the trainee to focus more on improving skills and practicing tactics.
[0027] Furthermore, the automatic recovery component includes a support rod 501, which is rotatably connected to the surface of the table tennis table 1 by bolts, so that it can be easily fixed on the surface of the table tennis table 1. It is not only easy to install, but can also be disassembled by simple rotation operation, which greatly simplifies the operation process and provides great convenience for users.
[0028] Furthermore, the support rod 501 is equidistantly rotatably arranged on the surface of the table tennis table 1, and the inner wall of the support rod 501 is clamped with a first blocking net 502. The first blocking net 502 is arranged on both sides of the table tennis table 1. When the practitioner sends the table tennis ball, the first blocking net 502 can intercept the table tennis ball when it is sent to both sides.
[0029] Considering that the ball launched from the front of the practitioner also needs to be intercepted, the bottom of the first blocking net 502 is in contact with the surface of the table tennis table 1, and the surface of the automatic serving machine 2 is provided with a second blocking net 503, which can intercept the ball launched from the front of the practitioner.
[0030] The second net 503 is clamped to the support rod 501 through the output end 3 of the automatic ball server 2. A dropping plate 504 is rotatably arranged on one side of the table tennis table 1 close to the automatic ball server 2. The dropping plate 504 is rotatably arranged at the bottom of one side of the table tennis table 1 close to the automatic ball server 2 through a resistance gear, and the dropping plate 504 is inclined, so that the second net 503 intercepts the intercepted table tennis balls and slides them along the dropping plate 504 to the input end 6 of the automatic ball server 2.
[0031] After the table tennis balls hit by the practitioner touch the second net 503, they will be effectively intercepted. Subsequently, these table tennis balls will naturally slide along the inclined dropping plate 504 and directly reach the input end 6 of the automatic ball server 2. The automatic ball server 2 sucks in the table tennis balls through its suction end, and after preparation, fires them again from the output end 3, realizing the automatic recycling and re-launching of the table tennis balls, greatly improving the practice efficiency, enabling the practitioner to focus on technical training without being distracted by cumbersome operations such as picking up balls and loading balls.
