Description
Technical field
The utility model relates to a kind of ball serving device, relates in particular to a kind of tennis service device, belongs to the sports goods technical field.
Background technology
Tennis is place motion at a high speed, liked by the teenager, but training is relatively more difficult, depends merely on air exercise because ball speed and poor placement are difficult to achieve the result.Specialty costs an arm and a leg with the tennis service device, and general universities and colleges are difficult to purchase to be afforded.
Summary of the invention
In order to address the above problem; The purpose of the utility model is to provide a kind of tennis service device; Through air pressure service, control valve control service frequency and ball speed, the start-up manually controls direction and drop point, can simulate the course of action of various service frequencies, ball speed, direction and drop point; Simple in structure easy to use cheap, be fit to very much the training of each universities and colleges and sports buildings place.
The utility model solves the technical scheme that its technical problem adopted: the tennis service device; It is made up of air pump, air pump pressure-control valve, tranmitting frequency control valve, cylinder control valve, cylinder, connecting rod, folding door-plate, ball-storing box, sealing ring, emission placket, silica gel pipe box, launching tube, launching tube holder device; Air pump is connected with emission placket rear end pipeline through the tranmitting frequency control valve; Air pump is connected with two pipelines with cylinder through cylinder control valve, and air pump also is connected with the air pump pressure-control valve.The ball-storing box lower end is connected with the emission placket through sealing ring, slidely connects the folding door-plate between the sealing ring, and the folding door-plate is connected with cylinder through connecting rod.The emission placket is connected with launching tube through the silica gel pipe box, and launching tube is connected on the launching tube holder device.Described launching tube holder device is made up of support, long tension spring, support, and six angles of support are connected with the launching tube periphery through six long tension springs, and support is fixed on the support.Being provided with opening in the middle of the described sealing ring is sealed and matched with the folding door-plate and is connected.
The beneficial effect of the utility model is: serve a ball through air pump compressed air air pressure; Through control valve control air pressure and service frequency; Through Artificial Control direction and drop point; Can simulate the course of action of various balls speed, direction and drop point, be fit to very that each is big, special secondary school universities and colleges and training center's tennis court training.
