Description

Technical Field

[0001] This utility model relates to the field of sports training equipment technology, and in particular to a ball-serving device for table tennis training. Background Technology

[0002] Table tennis is a popular ball sport worldwide, encompassing offense, competition, and defense. Matches are divided into team, singles, and doubles categories. Daily table tennis practice requires simulated training for coaches, including a specific exercise in serving. Traditionally, sparring partners serve the balls, a labor-intensive method. Therefore, automatic table tennis ball-serving machines have emerged on the market, capable of automatically serving table tennis balls for coaches to practice with.

[0003] A search of Chinese Patent Publication No. CN216061951U reveals a serving device for table tennis training, comprising a loading cylinder, an arc-shaped ball guide tube fixedly connected to the bottom outlet of the loading cylinder, a ball-collecting chamber rotatably sleeved at the ball outlet of the arc-shaped ball guide tube, a ball-shooting chamber fixedly connected to the bottom end of the ball-collecting chamber, a stop block fixedly connected to the bottom inner wall of the ball-shooting chamber, a sliding ball-shooting mechanism mounted on the ball-shooting chamber, and a continuous swinging mechanism fixedly mounted on the loading cylinder. The sliding ball-shooting mechanism includes a drive motor fixedly connected to one side of the ball-collecting chamber, a notched gear keyed to the output shaft of the drive motor, a fixed rack meshing with the notched gear, a sliding block fixedly connected to one end of the fixed rack, a fixed track slidably sleeved on the sliding block, one side of the fixed track fixedly connected to one side of the ball-shooting chamber, a reset ball-shooting assembly mounted on the sliding block, and a sliding feeding assembly mounted on the notched gear.

[0004] After the ball is returned by the trainer from the serving device, it scatters in various places, making it inconvenient to retrieve. The trainer needs to manually pick up the ball and put it back into the serving device, which has certain limitations. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-7 As shown, a table tennis training ball-serving device includes a base plate 1. The bottom of the base plate 1 is provided with casters for easy movement. The top of the base plate 1 is provided with a ball-serving mechanism. The ball-serving mechanism includes a lifting frame 201 bolted to the top of the base plate 1. A ball storage cylinder 202 is fixedly connected to the lifting frame 201. The bottom of the ball storage cylinder 202 is funnel-shaped. An installation box 203 is fixedly connected to the outer wall of the bottom of the ball storage cylinder 202. A guide tube 204 is fixedly connected to the bottom of the installation box 203. A launching tube 205 is hinged to the bottom of the guide tube 204.

[0029] The mounting box 203 is equipped with a shielding component, which includes an electric push rod 301 fixedly connected to the outer wall of the mounting box 203. The movable end of the electric push rod 301 is fixedly connected to a baffle 302, which is located inside the mounting box 203. By controlling the electric push rod 301 to drive the baffle 302 to move, the opening at the bottom of the ball storage cylinder 202 can be opened and closed.

[0030] A launching assembly is provided behind the launching tube 205. The launching assembly includes an air pump 206 bolted to the top of the base plate 1. An air supply pipe 207 is fixedly connected to the air outlet of the air pump 206. The other end of the air supply pipe 207 is fixedly connected to the rear of the launching tube 205 and communicates with the inside of the launching tube 205.

[0031] A collection mechanism is provided behind the ball-serving mechanism. The collection mechanism includes telescopic frames 401 fixedly connected to both sides of the base plate 1. Support seats 402 are fixedly connected to the telescopic frames 401. Support rods 403 are plugged into the top of the support seats 402. A protective net 404 is fixedly connected between the two support rods 403. A collection box 405 is placed on the top of the base plate 1.

[0032] Two sets of guide components are symmetrically arranged on the telescopic frame 401 in front of the protective net 404. The guide components are used to guide some of the ping-pong balls into the collection box 405. The guide components include a slide rod 501 that is pluggably connected to the top of the telescopic frame 401. A guide plate 502 is slidably connected to the slide rod 501. The guide plate 502 is fixed to the slide rod 501 by a locking bolt. The two sets of guide plates 502 are arranged in a V-shape with the small opening facing down, which makes it easy for the ping-pong balls to fall into the collection box 405.

[0033] A negative pressure component is provided below the guide component. The negative pressure component provides a suction force to bring the ping-pong ball close to the guide component. The negative pressure component includes several exhaust fans 503 fixedly connected to the bottom of the guide plate 502. Ventilation holes are provided on the top of the guide plate 502.

[0034] Working principle: In use, move the base plate 1 to a suitable position, insert the support rod 403 into the support base 402, insert the guide plate 502 from the top of the slide rod 501, adjust the guide plate 502 to a suitable height according to the trainee's strength and other habits, tighten the locking bolt to fix the height of the guide plate 502, and control the electric push rod 301 to move the baffle 302, opening the opening at the bottom of the ball storage tube 202. The ping-pong ball falls into the launching tube 205 through the guide tube 204. Then, control the electric push rod 301 to move the baffle 302... The opening at the bottom of the ball storage cylinder 202 is sealed, and the air pump 206 is started to supply high-pressure gas to the launching tube 205 through the air supply pipe 207, thereby launching the ping-pong balls in the launching tube 205. After the launched ping-pong balls are hit back by the trainer, some of the ping-pong balls are hit onto the protective net 404, which blocks some of the ping-pong balls. At the same time, the exhaust fan 503 is started to provide suction force to the ping-pong balls near the guide component, so that the ping-pong balls fall into the collection box 405 under the guidance of the guide plate 502, reducing the workload of picking up ping-pong balls and improving the collection efficiency.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
