FIG. 1 is a schematic structural view of a tennis ball hitting trainer according to an embodiment of the present invention;
the device comprises a base 1, a support leg 11, a hollow tube 12, a resistance increasing rubber block 13, a balancing weight 14, a telescopic rod 2, a cross rod 3, an annular groove 31, a positioning ball serving structure 4, an elastic rope 41, an elastic rope 42, a positioning rod 43, an elastic annular rope 44 and a pull rope.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, a tennis batting exerciser, including base 1, telescopic link 2, horizontal pole 3 and location service structure 4, base 1 includes three landing leg 11 and perpendicular ascending hollow tube 12, telescopic link 2 pegs graft in hollow tube 12 internal fixation, three landing leg 11 is located same horizontal plane, and each other is 120 degrees in proper order, landing leg 11 sets up the balancing weight 14 to the tip of outside, the bottom sets up resistance increasing glue piece 13, traditional inconvenient mode that attaches heavily with the water bag has been abandoned, the steadiness of simpler increase base 1. The cross rod 3 is also of a telescopic rod structure, the center of the cross rod 3 is connected with the telescopic rod 2, at least one side of the cross rod 3 is provided with at least one set of positioning ball serving structure 4, each positioning ball serving structure 4 comprises an elastic rope 41 which is connected with the cross rod 3 and is in a V shape, the other end of each elastic rope 41 is connected with a positioning rod 42, the other end of each positioning rod 42 is connected with an elastic ring rope 43, and the positioning rods 42 are horizontally arranged to enable the elastic ropes 41 in the V shape to keep a distance from the elastic ring ropes 43; the elastic ring rope 43 is used for elastically binding the trial ball, the cross rod 3 is also connected with a pull rope 44, the pull rope 44 is an elastic rope, one end of the pull rope 44 is connected with the cross rod 3 in the middle of the V shape, the other end of the pull rope 44 is connected with the trial ball, and the length of the pull rope 44 is larger than the distance from the cross rod 3 to the connection point of the trial ball, so that the pull rope 44 is in a loose state. The cross rod 3 is of a telescopic rod structure, is convenient to store, and can be provided with a plurality of positioning ball serving structures 4 on one side, so that continuous hitting training of a trainer can be realized; the positioning service structure 4 comprises a V-shaped elastic rope 41 connected with the cross rod 3, the other end of each elastic rope 41 is connected with a positioning rod 42, the other end of each positioning rod 42 is connected with an elastic ring rope 43, the positioning rods 42 are horizontally arranged, the elastic ring ropes 43 elastically bind the trial balls, when the trial balls are hit, the trial balls are upwards rotated under the action of forward and upward force, and the V-shaped elastic ropes 41 are arranged to enable the elastic ropes 41 not to restrain the force generated by the trial balls at the upper part and the lower part and to be close to the actual hitting effect; the arrangement of the positioning rod 42 further keeps the distance between the V-shaped elastic rope 41 and the elastic loop rope 43, and further avoids the obstacle of the elastic rope 41 to the batting operation of the trial ball. The loose elastic pulling rope 44 firstly does not affect the upward rotation of the trial ball when the ball is hit, secondly, the pulling rope generates a pull-back force to the flying trial ball when the trial ball is separated from the elastic ring rope, and the trial player can take back the trial ball through the pulling rope 44, thereby avoiding the fatigue of repeatedly running to pick up the ball. Set up annular groove 31 on the horizontal pole 3, the elasticity rope 41 and the stay cord 44 of "V" style of calligraphy are tied up respectively in annular groove 31, can carry out standard location to elasticity rope 41 and stay cord 44, are difficult to the location when avoiding installing elasticity rope 41 and stay cord 44 at every turn, and the problem that "V" font opening angle of difference is different to the batting effect.
Two sides of the cross bar 3 are respectively provided with two sets of positioning service structures 4, and each side can be used for one trainer to carry out continuous hitting training or one side can be used for two trainers to carry out training simultaneously. According to the size standard of a tennis court, the length of the pull rope 44 is not less than 11885mm, and when a test ball is hit in a suspension state, the acting force of the pull rope 44 on the test ball is almost zero, so that any adverse effect is not caused on the hit ball; on the other hand, when the trial ball is played, the long pull rope 44 hardly influences the angle, force and rotation direction of the trial ball to reflect the hit flying, and only timely pulls the trial ball when the tail sound is close, so that the truth of hitting the trial ball is not influenced, and the trial player is prevented from repeatedly running to pick up the trial ball. The locating lever is the thin aluminum pipe of cavity, and the other end of the elastic rope of middle "V" style of calligraphy is passed to be connected with the elasticity looped rope, thin aluminum pipe matter is light on the one hand, when keeping apart the distance of elasticity rope and elasticity looped rope, alleviates the influence to the batting effect again as far as possible, and tubular structure also makes the locating lever can follow the adjustment of elasticity rope at will in addition, convenient storage.
