Description
Technical field
The utility model belongs to the sports equipment field, more particularly, relates to a kind of can freely the service and operation flexibly in orbit through the Single-chip Controlling table tennis.
Background technology
Table tennis is the national ball game of our China, and is very universal in "sport for all", but the sportsman can in international tournament, obtain proud achievement and training at ordinary times is undivided.The sportsman is in training; Basically all lean on two people each other to practising, both sides' strength is different, and technological good sportsman just might not reach the effect of the training of oneself wanting; And the training time need two people cooperate arrangement jointly, not free in time.In order to address this problem, people have invented table tennis ball-serving device, can utilize table tennis ball-serving device, and exercise is received alone, more convenient freedom, and still existing table tennis ball-serving device complex structure, and serving side is to single, and variability is not strong.Table tennis training machine appears on the market already, and of all kinds, but function is more single, is leading with launching balls basically.
For example Chinese patent number is 200810163261.X, and the applying date is the applying date: 2008-12-12, this disclosure of the Invention a kind of table tennis ball-serving device; Comprise pedestal, first motor, support and be fixedly installed on the storage ball box on the support; Pedestal is provided with the transmitting tube that is interconnected and goes into bulb, goes into bulb and is interconnected through being connected flexible pipe with storage ball box, and characteristics are that pedestal is provided with first inner chamber; First inner chamber through ball-dropping hole with go into bulb and be interconnected; The output shaft of motor stretches into first inner chamber and is provided with the emission bat that is used to bounce table tennis, and pedestal is provided with at least one roller, and roller is provided with depth adjustment; Advantage is because the output shaft of first motor is provided with the emission bat, and pedestal is provided with roller, when emission bat rotating tee is crossed roller; Can will launch to clap and depress backward; When breaking away from roller, eject the table tennis that drops on the ball-dropping hole through the bounce-back that emission is clapped, and roller is provided with depth adjustment; The scalable roller stretches into the degree of depth in first inner chamber, thereby can adjust the dynamics of emission table tennis through the bounce that the control emission is clapped.This invention realizes simple table tennis emission through devices such as roller and motors, does not move and automaton, and the multiple fancy ball emission in moving can't be provided; Be not difficult to find out; Complex structure and function are simpler, let the people feel dull boring unavoidably in these epoch of advocating " amusement fashion ", are difficult to reach the training effect of expection; The most fatal is if the adjusting of own manual adjustments emitter is unprofessional, and training will be tried to be clever only to end up with a blunder.
Summary of the invention
The problem that solves
Can not be in the existing table tennis training system in order to overcome along the track action; Can't send out to flexible and controllable system the deficiency of free kick; The utility model provides a kind of table tennis training system; This training system not only can move along track designation, and can freely launch the ball of multi-angle, rotation through Single-chip Controlling.
