The content of the invention
The utility model utilizes theory of mechanics, using the elastic force of spring as mainly by power.Due to during ball is picked up Do not rub very little to tennis, does not result in tennis damage.The utility model provide it is a kind of it is cheap, need not lubricate and delay Punching, shock-absorbing, the novel tennis ball of easy care pick up ball machine.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals:A kind of novel tennis ball Pick up ball machine, including tennis collecting box, holding rod, pull bar, spring, fixed pulley, baffle plate, cord.Tennis collecting box is cuboid, and Tennis collecting box lower end corner is provided with roller.Tennis collecting box upper end is provided with opening, and the installation of pull bar, pull bar are can be used at opening Opening is fixed on by bottom screens.Pull bar is inclined relative to tennis collecting box upper surface, and pull bar upper end is additionally provided with holding rod, holding rod Vertical with pull bar, holding rod is tightly fixed in pull bar by the external thread rotary of bottom.Pull bar bottom is further fixed on fixed pulley one.Tennis The opening of collecting box upper end is fixed with fixed pulley two with tennis collecting box upper end intersection.The bottom of tennis collecting box is fixed frame Frame.Fixed frame positioned beneath movable framework.The underface tennis collecting box bottom of fixed pulley two is provided with fixed pulley three, cord from Holding rod bottom is wound to fixed pulley one, fixed pulley two, fixed pulley three, and cord terminal is tied to red framework one end.Tennis collecting box Right side is provided with baffle plate, and baffle plate top is connected with spring with tennis collecting box right side bottom.
The fixed frame and movable framework are isometric with tennis collecting box wide, and spacing is between the reinforced bar of bottom 10cm。
The movable framework side is with tennis collecting box bottom inside for left and right is slidably fixed.
The fixed pulley one, fixed pulley two, fixed pulley three are fixed on holding rod bottom, tennis collecting box centrally through fixed mount Left upper end, tennis collecting box lower-left end.
The utility model is in inactive state, and fixed frame and mobility framework are alternate, at a distance of 5cm between correspondence reinforced bar. When using, pull bar, rope is pulled to be changed the direction of power by fixed pulley with pull bar displacement 5CM, rope, finally drawn at ground proximity Dynamic movable framework.Movable framework displacement 5CM, and black fixed frame overlaps, and now spacing is 10cm or so between framework, Tennis can enter net in collecting box by reinforced bar.Hand holds holding rod, lifts ball case, and spring pulls baffle plate by a large amount of tennis frames Firmly, pull bar is now put down, because spring tension effect can cause red mobility framework to return to initial position.Now, red framework With black frame at a distance of 5CM, will not be spilt because tennis diameter is about 6.6CM.
Novel tennis ball of the present utility model picks up ball machine has advantages below:The utility model simple structure, protects tennis not It is worn, bar is detachable, it is easy to carry, cost is relatively low and suitable for any tennis court.
