Abstract
The utility model discloses a training device for over-net height of a table tennis ball. The training device for the over-net height of the table tennis ball comprises a table tennis net, extending support pillars are arranged on support pillars at two ends of the table tennis net, five groups of infrared detection devices are arranged on the extending support pillars from top to bottom in sequence in an equidistance and parallel mode, each group of infrared detection device is formed by an infrared signal transmitting tube and an infrared signal receiver, the infrared signal transmitting tubes and the infrared signal receivers are respectively installed on the extending support pillars at two ends of the table tennis net, the infrared signal receiver of each group of infrared detection device is connected with an independent photoelectric counter, and a power supply supplying power for the infrared detection devices and the counters is arranged below a table. The training device for the over-net height of the table tennis ball cannot disturb a player in a using process, training cannot be interrupted, and the data of the over-net height of the table tennis ball can be counted.
Description
Technical field
The utility model relates to a kind of table tennis training auxiliary appliance, and is especially a kind of for training the paddler table tennis to be crossed the device of net height control ability.
Background technology
In the ping-pong contest process, table tennis is crossed the quality that net height is often determining batting, from technological layer, lower ball more is not easy the chance had an effect to the opponent, low flat batting also easily causes making a faulty return of opponent, therefore, in the multinomial batsmanship of table tennis, as serve a ball, chop the chop, forehand attack, backhand attack, push and block, accelerated loop etc. have all proposed certain requirement to the height of batting.Because sportsman or coach judge the height of batting with naked eyes, be difficult to complete the sportsman table tennis is crossed the high-quality of net height control ability, training targetedly.CN202460024U discloses a kind of table tennis ball for training net, this table tennis ball for training net is made of upper and lower two-layer net, utilize space in the middle of two-layer net to regulate trainee's batting height, and be used for testing and controlling the height of return of serve, but when adopting the table tennis ball for training net training of this structure, in case ball touches online, training has just been ended, and can't add up the return of serve height in a whole set of training.
The utility model content
The technical problem that utility model will solve is: provide a kind of table tennis to cross the net height trainer, this device in use can not produce interference to the sportsman, can not interrupt training, and can cross the net height data to table tennis and add up.
the technical scheme that the technical solution problem is taked: a kind of table tennis is crossed the net height trainer, comprise table tennis net, be provided with the prolongation pillar on the pillar at table tennis net two ends, equidistant parallel arranges 5 groups of infrared detection devices extending on pillar from bottom to top successively, every group of infrared detection device is made of an infrared signal transmitting tube and an infrared signal receiver, infrared signal transmitting tube and infrared signal receiver are arranged on respectively on the prolongation pillar at table tennis net two ends, the infrared signal receiver connection one of every group of infrared detection device is photoelectric counter independently, divide into the power supply of promising infrared detection device sum counter power supply at billiard table.
As improvement of the present utility model: the spacing of every group of infrared detection device is 40 millimeters, and the infrared detection device of below is positioned on the horizontal line of 40 millimeters height of table tennis net upper limb.
As further improvement of the utility model: the infrared signal receiver of every group of infrared detection device connects a sound and light signal prompting device independently, and described sound and light signal prompting device is made of trigger switch, signal lamp and buzzer.
Further improve as of the present utility model: the signal lamp in each sound and light signal prompting device is the signal lamp of different digital or letter shapes again.
Improve as another kind of the present utility model: the signal lamp in each sound and light signal prompting device is the cue light of different colours.
effective effect: table tennis of the present utility model is crossed the net height trainer, comprise table tennis net owing to having adopted described table tennis to cross the net height trainer, be provided with the prolongation pillar on the pillar at table tennis net two ends, equidistant parallel arranges 5 groups of infrared detection devices extending on pillar from bottom to top successively, every group of infrared detection device is made of an infrared signal transmitting tube and an infrared signal receiver, infrared signal transmitting tube and infrared signal receiver are arranged on respectively on the prolongation pillar at table tennis net two ends, the infrared signal receiver connection one of every group of infrared detection device is photoelectric counter independently, divide into the technical scheme of the power supply of promising infrared detection device sum counter power supply at billiard table, realized that by on the prolongation pillar, the infrared detection device sum counter being set table tennis is crossed net height to be added up, therefore, this table tennis is crossed the net height trainer in use can not produce interference to the sportsman, ball can not interrupt training during by top, infrared acquisition zone yet, and can cross the net height data to table tennis and add up, adopt this device to carry out table tennis training, can improve the paddler and table tennis be crossed the control ability of net height, improve athletic technical merit, because the spacing that has adopted every group of infrared detection device is 40 millimeters, the infrared detection device of below is positioned at the technical characterictic on the horizontal line of 40 millimeters height of table tennis net upper limb, the ball that passes through in the infrared acquisition zone above net all can be added up accordingly according to different height, provide Data support for the sportsman analyzes, improves training, because the infrared signal receiver that has adopted every group of sniffer connects a sound and light signal prompting device independently, described sound and light signal prompting device is by the technical characterictic that trigger switch, signal lamp and buzzer consist of, and makes the sportsman just can know at the sound that sends according to the sound and light signal prompting device in a flash of over the net or light whether table tennis is positioned at infrared acquisition zone above net, be the technical characterictic of the signal lamp of different digital or letter shapes owing to having adopted the signal lamp in each sound and light signal prompting device, make the sportsman can judge rapidly that according to the shape of luminous signal lamp table tennis is apart from the height of top of the net, be the technical characterictic of the cue light of different colours owing to having adopted the signal lamp in each sound and light signal prompting device, make the sportsman can judge rapidly that according to the color of luminous signal lamp table tennis is apart from the height of top of the net, in order in time revise next shot according to the height of return of serve, improve thereby reach the control ability that table tennis is crossed net height.
