Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a take tennis training ware of rotatable tennis, including portal 1, portal 1 front side sliding connection has elastic panel 2, portal 1 rear side fixed connection has elastic net 3, portal 1 upper end middle part fixedly connected with fixed block 4, 4 one end fixedly connected with electric telescopic handle 5 of fixed block, 5 other end fixedly connected with supports 6 of electric telescopic handle, this kind of rotation of supports 6 is connected with pulley 7, portal 1 upper end is located 4 rear sides of fixed block and is equipped with hoist engine 8, fixed connection is in 9 one end of elasticity rope on the hoist engine 8, the elasticity rope 9 other end runs through fixed block 4 and twines in pulley 7, elasticity rope 9 fixed connection is in tennis 10.

Wherein, portal 1 front side is equipped with scale 11, can adjust the height of elastic panel 2 according to scale 11 to adapt to the training requirement of difference and the use of different height crowds. The equal fixedly connected with limiting plate 12 in elastic panel 2 both ends, T type groove 13 has all been seted up at the inboard both ends of portal 1, and limiting plate 12 sliding connection can be fixed elastic panel 2's position through limiting plate 12 and the mutually supporting in T type groove 13, prevents the skew, and is better to tennis 10's bounce-back effect. The outer side of the group of limiting plates 12 is fixedly connected with a threaded sleeve 14, a cavity 15 matched with the threaded sleeve 14 is formed in the door frame 1, and the threaded sleeve 14 can move up and down in the cavity 15. A driving motor 16 is fixedly connected to one side of the upper end of the door frame 1, a threaded rod 17 is fixedly connected to a power shaft end of the driving motor 16, the other end of the threaded rod 17 penetrates through the door frame 1 and extends into the cavity 15, and one end, located in the cavity 15, of the threaded rod 17 is rotatably connected to the bottom end of the cavity 15 through a bearing 18. Threaded rod 17 runs through threaded connection in threaded sleeve 14, through driving motor 16, can drive threaded rod 17's rotation, and then makes threaded sleeve 14 remove on threaded rod 17 to adjust the height of elasticity panel 2.

One specific application of this embodiment is: when the tennis racket is used, the position of the tennis ball 10 is adjusted according to a training item, and the electric telescopic rod 5 can be started, wherein the electric telescopic rod 5 is a product in the prior art, is commercially available and can be directly purchased for use, and the electric telescopic rod 5 drives the bracket 6 and the pulley 7 at the front end to move, so that the distance between the tennis ball 10 and the elastic panel 2 is adjusted. After the adjustment is completed, the winch 8 can be started to adjust the height of the tennis ball 10, so that the length of the elastic rope 9 between the pulley 7 and the tennis ball 10 is greater than the linear distance between the pulley 7 and the elastic panel 2, at this time, the driving motor 16 can be started to drive the screw rod 17 to rotate, and therefore the screw sleeve 14 drives the elastic panel 2 to move up and down and move to a proper position according to the scale 11. At this time, the trainee can flap the tennis ball 10, and the elastic string is not completely stretched when the tennis ball 10 contacts the elastic panel 2, so that the tennis ball 10 is only stressed by the racket during the flying process, thereby sufficiently reducing the external interference, and the elastic panel 2 can bounce the tennis ball 10 to simulate the fighter, thereby achieving the actual combat training effect.
