Embodiment Construction
[0027] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0028] Such as figure 1 As shown, a pneumatic tennis training device includes a housing 1, a horizontal scoring pipe 2, a vertically arranged ball outlet pipe 3, an air pump 4 communicating with the ball outlet pipe and located below the ball outlet pipe, including a photosensitive The bearing platform 5 of the sensor 17 is provided with a hingedly fixed limit bracket 6 in the housing. The limit bracket includes a horizontally arranged push rod 7 and a vertically arranged limit rod 8. The first opening 9 for the rod to enter and exit, one end of the push rod is passed through the opening, one end of the push rod can be in contact with the circumferential side edge of the bearing platform and is located inside the ball discharge pipe, the other end of the push rod is connected to the bottom of the limit rod, The side wall of the ball pipe is pro...

The invention discloses a tennis training device, and aims to provide an air pressure type tennis training device which adopts a mechanical structure and has an automatic ball supplementing function.The device comprises a shell, a ball inlet pipeline, a ball outlet pipeline, an air pump, a bearing platform and a limiting bracket; the limiting bracket comprises a horizontally-arranged pushing rodand a vertically-arranged limiting rod; a first opening which allows the pushing rod to enter and exit is formed in a side wall of the ball outlet pipeline; one end of the pushing rod is arranged in the opening in a penetrating mode; one end of the pushing rod can be in contact with the circumferential side edge of the bearing platform and is positioned in the ball outlet pipeline; the other end of the pushing rod is connected with the bottom of the limiting rod; a second opening which allows the limiting rod to enter and exit is formed in a side wall of the ball inlet pipeline; the top of thelimiting rod can move upwards to enter the ball inlet pipeline through the second opening, and then intercept a tennis ball inside the ball inlet pipeline; and after the tennis ball in the ball outlet pipeline is blown up by the air pump, the limiting bracket can rotate clockwise and exit from the ball inlet pipeline, and the tennis ball can be automatically supplemented into the ball outlet pipeline.
Description
technical field [0001] The invention relates to a physical training device, in particular to a pneumatic tennis training device. Background technique [0002] Tennis is a sport in which athletes hit tennis balls effectively during their flight. When a beginner is practicing tennis, because the height and flight trajectory of the tennis ball are not well judged, the effect of hitting the tennis ball is not good, and the technical action of hitting the tennis ball cannot be stabilized and solidified. In order to improve the batting accuracy of the athlete, there are two existing methods: one is to feed the ball artificially, and the other is to supply the ball by a ball-serving machine. The former requires more manpower, and the ball supply method is unstable, which is greatly affected by human factors; the latter's ball supply method is more mechanical, uses an ejection device, and the speed is too fast, which increases the difficulty for the batter to practice the ball. ...
