Description
Affiliated technical field
The present invention relates to a kind of wind spring type tennis ejecting apparatus, belong to the sports goods field, be specifically related to tennis exercise catapult-launching gear.
Background technology
The present invention is a kind of tennis catapult-launching gear, have following several with this bright immediate prior art: the multi-functional tennis serve machine (patent No.: 95205606.2), the tennis toss device (patent No.: 96222872.9), a kind of tennis exercise apparatus (patent No.: 96215081.9), tennis Partner training device (the patent No.: 96241893.5), tennis-exercising device (the patent No.: 97203045.X), the single no net tennis (patent No.: 200320104620.7) of pleasing oneself, the tennis toss exercising machine (patent No.: 200310106676.0), electronic interesting tennis-exercising device (the patent No.: 200510023889.6), tennis serve machine (the patent No.: 200620090512.2) of training usefulness, the energy storage type service robot (patent No.: 200620097178.3), the continuous high speed resilience tennis-exercising device (patent No.: 200620012183.X).Above equipment or Design of device purpose all are to learn or consolidate the tennis technical movements and offer help for tennis training person (special beginner), and the practitioner can be practised continuously separately, increase enjoyment simultaneously.From the formation of equipment, above equipment can divide two big classes with device: a kind of is the device (category-A) that is connected a traditional thread binding thing on the tennis, and a kind of is by motor-driven, and tennis is thrown the equipment (category-B) of bullet successively by the program that sets in advance.The practitioner practises actual effect from tennis, the category-A device can not just really help the beginner to improve the tennis technical movements, they are to be easy to just can allow the beginner that the enjoyment that impacts ball is for the moment arranged, but often ignored the stage of begining to learn to grasping the standardization of tennis technical movements, particularly the exercise impact screw (on revolve, backspin) the tennis track is strange unusually and during direction, however practitioner's what posture that don't work removes to impact ball, tennis all can be subjected to the thread tractive and quicken to rebound, make the batsmanship action be out of shape, technology does not have the possibility of sustainable development, the beginner just loses the interest to tennis study probably, thereby stops to carry out tennis.Category-B equipment, because its automaticity is higher, price is also higher, safeguards and carry also to bother.It still is fewer that the individual buys, because can leave unused at the action back equipment that masters a skill, and obviously a bit waste after the disposable input.If buy, expensive equipment is used and manages and can bring a lot of troubles and inconvenience by collective.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, low-cost wind spring type tennis ejecting apparatus.
A kind of wind spring type tennis ejecting apparatus is characterized in that: comprise that tennis keeps in cabin, ejection capsule, clockwork spring transmission mechanism;
The temporary cabin of above-mentioned tennis one end is provided with the tennis inlet, and the other end is provided with ball feeding device;
Above-mentioned ejection capsule is by the fixed muffle of end sealing and be placed in the movable part that can move in the fixed muffle form in fixed muffle; Have spring door and shifting block on the movable part, be provided with spring between the spring door of movable part and the fixed muffle bottom, by the spring door ejection capsule has been divided into spring cavity and ejection chamber two parts, ejection chamber top is provided with the ejection chamber outlet; Fixed muffle has two lateral openings, one of them opening is the ejection chamber inlet, another opening is the shifting block slideway, the temporary cabin of tennis communicates by the ejection chamber inlet with ejection chamber, ejection chamber inlet is sealed by movable part during general state, and when shifting block is stressed when making that movable part glides, spring compression and ejection chamber inlet are temporarily opened, tennis is sent into ejection chamber by ball feeding device, and tennis relies on the spring restoring force to eject from the ejection chamber outlet subsequently;
Have near the above-mentioned shifting block and stir the wheel that starts that shifting block moves down, start wheel to link to each other with spring motor.
The present invention is the auxiliary equipment of tennis beginner exercising net playing skill art, and when particularly impacting institute's toss in the original place, the distance of people and ball and impacting on the height of ball was very helpful when cognition was impacted ball.Can be used in positive and negative forehand hit technology, halting batsmanship, service and the begining to learn the stage of smash technology.It also can be accomplished to the practitioner supplies ball continuously, helps the practitioner to form dynamic stereotype as early as possible.It will cooperate the place to practise, and effect can be more.It possesses the benefit of exercise alone equally, can be aim to grasp correct tennis technical movements batting at the very start again.It is also easy to carry and use.Also be more cheap for the cost of disposable input.If use in school, can strengthen the independence of student's exercise greatly, teacher no longer limit toss limit corrects action, and student's exercise intensity also can correspondingly increase, and the error of having avoided own toss to bring has strengthened the notice to shot.
Technical conceive of the present invention derives from the practical teaching and the tennis technological sciences teaching method of tennis technology.The present invention can practise separately, needs the collaborative exercise of two people (not needing the tennis basis) sometimes.Begining to learn positive and negative hand and halting action phase, at first be the no ball practice stage of action, next be original place toss practice stage, a step is slowly to strengthen the toss distance again, up to filter toss practice stage, at last to impacting the other side's bottom line ball practice stage.The present invention can finely must help the beginner to finish above each stage exercise.Begining to learn in the stage in service, at first is the toss exercise, and ball is thrown to have stablized just and can be impacted good shot, has elongated service technique so virtually and has taken the time, if practise synchronously with slance, just auxiliary equipment must be arranged.The present invention can reach this purpose just, and toss technology and slance exercise in pace with studying are independent of each other, and can promote to some extent on the contrary.Begin to learn the stage in smash, impact ground ball earlier and impact volley again, impact the near distance that impacts again of distance earlier, slow fast of first striking speed at striking speed.The present invention also can be fine finish when exercise for the ball task.Increase quantity of the present invention and can also design and the technical application combined training, as alternately batting training of froehand-backhand, man-computer cooperation training etc.
