Abstract
The invention discloses a tennis ball dispenser, which comprises an air pump, a distribution device and an emission device, wherein the emission device consists of an emission pipe sleeve, an emission pipe and a ball rotating pipe sleeve; the emission pipe sleeve comprises a silicon rubber pipe; the inner diameter of the silicon rubber pipe is slightly less than the diameter of a tennis; and a pipe collar with an adjustable inner diameter is arranged on the outer pipe wall of the silicon rubber pipe. An emission sleeve manufactured by the silicon rubber pipe with high elasticity and contractibility is combined with the pipe collar with an adjustable pipe diameter, so that the increase of the emission speed of an instant ball is facilitated, and a ball body can be conveniently emitted within different distances by adjusting the pipe diameter; in addition, a ball rotating sheet which is arranged in the ball rotating pipe sleeve at the front end of the tennis ball dispenser contributes to ball rotation, and flying tracks can be changed when the flying ball way of the ball rotating sheet is influenced by a spiral line, so that training is more similar to actual matches.
Description
Technical field
The present invention relates to a kind of athletic training and use utensil, particularly a kind of tennis transmitter.
Background technology
In tennis practice and training, the use of mechanical tee has been more and more applications, Chinese patent discloses a method for training CN201394334Y tennis machines, including motor, the ball plate, the ball mouth, the ball channel and Crank joystick mechanism and other components, Chinese patent also discloses a storage CN2899874Y tennis serve Zhua, mainly by the cabinet, gear box, sending the ball institutions and storage bodies, the above patent, although the technical solution adopted in tennis tee function has been changed trap, but there are structural manufacture of complex, high cost of inadequate training ground is difficult to spread to small and general consumers.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and in simple and practical, low cost of manufacture, in distance, speed and the rotation of ball operation, all can realize the tennis service device that fidelity is higher.
Technical scheme of the present invention is: a kind of tennis service device; Comprise air pump, dispenser and emitter; Wherein: above-mentioned dispenser by carry a ball bucket, can be by the rotating disk of the at interval single ball output of certain hour, lead the bulb road, the release pipeline is formed; One end of said release pipeline is connected with air pump, and the said bulb road of leading is connected with the release pipeline, and the said other end of leading the bulb road is connected in the ball mouth of rotating disk below; Above-mentioned emitter is made up of emission pipe box, transmitting tube, spiral pipe box, and said emission pipe box comprises silicone tube, and the internal diameter of above-mentioned silicone tube is slightly less than the sphere diameter of tennis, is provided with the pipe collar of scalable bore at the outer tube wall of silicone tube.
Further: be provided with near the ball inlet side at above-mentioned silicone tube and be trumpet-shaped introduction segment.Pipe cylindrical wall at above-mentioned silicone tube is equipped with some avoiding hollow grooves.
Again further: above-mentioned spiral pipe box and transmitting tube are provided with in the pore of spiral pipe box for spinning
The spiral sheet that is tooth bar shape or helical tooth bar shape, above-mentioned spiral sheet are that elastomeric material is made.
The present invention is owing to adopted the pipe collar of the emission noose unification scalable caliber with the good silicone tube making of elastic shrinkage; The speed of not only favourable increase moment ball emission, and can realize that through regulating caliber the spheroid different distance has emission easily, in addition; The spiral sheet that in front end spiral pipe box, is provided with; When helping spiral, its flight alley receives helical to influence the variation that can produce flight path, makes training more approaching under battle conditions.
