TECHNICAL FIELD

[0001] The present application relates to the field of tennis training equipment, in particular to a tennis swing posture fixing training device. BACKGROUND

[0002] Tennis is a ball game, usually between two single players or two pairs. Players hit the ball with a tennis racket on the tennis court. Modern tennis originated in Birmingham, England in the 19th century, and was originally called "lawn tennis". Since then, tennis has developed rapidly, and the first Grand Slam tournament, Wimbledon, was established in 1877, followed by the US Open in 1881, the French Open in 1891, and the Australian Open in 1905, i.e. the four Grand Slam tournaments.

[0003] For beginners of tennis, in order to play good tennis, they need to train a lot of ball hitting actions, and the standardization of actions is related to the development of ball skills in the later period. At present, the training of ball hitting actions mainly relies on repeated training by individuals, so a device that can assist in positioning posture during tennis training is needed. The prior art usually requires the trainee to practice beside the wall by drawing guide lines on the wall, and the trainee follows the guide lines to practice, which has high requirements for the training site, and when there are many trainees, it is often difficult to meet the simultaneous training requirements. SUMMARY

[0004] The purpose of the present application is to provide a tennis swing posture fixing training device which can effectively assist training personnel in tennis swing training, and the device has simple structure, small floor area and is easy to store.

[0035] Embodiment 1

[0036] Please refer to Figure 1 , Figure 1 The figure shows the three-dimensional structure of the present embodiment.

[0037] The present embodiment provides a tennis racket swing posture fixing trainer, which comprises a limiting body 1, the limiting body 1 is hollow and the hollow part can pass through the front part of the tennis racket, and one side of the hollow part has an opening; the limiting body 1 is arranged on the support 2. The device passes through the limiting body 1, so that the limiting body 1 can limit the swing path of the training personnel. When in use, the training personnel stands on one side of the device to practice swinging, and only when the training personnel swings the tennis racket along the predetermined line and passes through the hollow part of the limiting body 1, the training personnel can complete the swing action, and the swing action of the training personnel can be accurately trained. It can be understood that the opening of the hollow part of the limiting body 1 can pass through the racket shaft of the tennis racket.

[0038] In the embodiment, the limiting body 1 is a curved hollow cylinder, and the hollow cylinder has an opening penetrating through both ends on one side. It can be understood that the curved path of the hollow cylinder is the same as the standard swing path; the limiting body 1 can also be other hollow structures. The limiting body 1 with the curved path can limit the swing path of the training personnel.

[0039] The existing tennis swing training is usually to let the trainees practice beside the wall, and the trainees follow the guide line drawn on the wall to practice, which requires a high training site. Moreover, the swing action of the trainees still has a lot of problems, and the trainer needs to follow and correct the trainees, which consumes a lot of site and manpower and has low training efficiency. The limiting body 1 provided by the support 2 has small occupation area and high adaptability to the site, and can be practiced in outdoor, indoor or balcony. The trainees can correct most of the wrong actions through the limiting body 1, and can complete the single and independent training of the trainees, which not only saves the time of the trainer, but also meets the requirement of the trainees to train alone at home, and greatly improves the training efficiency.

[0040] Meanwhile, the device is composed of the limiting body 1 and the support 2, has simple structure, is convenient to use, and has small occupation area. Further, the limiting body 1 and the support 2 are detachably connected, and can be connected by pin connection, bolt connection and the like. When the training is not needed, the limiting body 1 and the support 2 can be separated and stored to save space.

[0041] Embodiment 2

[0042] Please refer to Figure 2 , Figure 2 The figure shows the three-dimensional structure of the embodiment.

[0043] The embodiment provides a tennis swing posture fixing trainer, which comprises a limiting body 1, the limiting body 1 is hollow and the front part of the tennis racket can pass through the hollow part, and the hollow part has an opening on one side; and the limiting body 1 is arranged on a support 2. The embodiment is basically the same as the embodiment 1, and the main difference between the two is that the limiting body 1 is provided with a plurality of limiting bodies.

[0044] In the embodiment, the limiting body 1 is a frame, and the frame has an opening on one side. The plurality of limiting bodies 1 can form a specified swing route by adjusting the positions of the limiting bodies. Moreover, the frame is designed to be more portable and easy to store. Meanwhile, the portable limiting body 1 will not cause too much damage to the racket when the trainee makes a wrong action, and only one limiting body 1 needs to be replaced when the limiting body is damaged, which saves the maintenance cost.

[0045] Embodiment 3

The embodiment is basically the same as the embodiment 2, and the main difference between the two is that the support 2 comprises a supporting frame 3 and a base 4, one end of the supporting frame 3 is connected with the upper end of the base 4, and the other end is connected with the lower end of the limiting body 1.

[0048] In the embodiment, one supporting frame 3 is arranged corresponding to each limiting body 1. The supporting frame 3 is a goose neck pipe, and a training personnel can bend the goose neck pipe according to the specific conditions of the body such as height and arm span, so as to arrange the limiting body 1 at a swing position matched with the training of the training personnel. The arrangement of the goose neck pipe greatly flexibly enables the limiting body 1 to move, and the swing path formed by the multiple limiting bodies 1 can meet the training requirements of most swing skills; meanwhile, because the goose neck pipe can be bent under stress, the goose neck pipe can be bent under stress when the training personnel swings incorrectly and the tennis racket hits the limiting body 1, which greatly reduces the possible damage of the racket to the limiting body 1 and greatly increases the service life of the device.

[0049] The bottom of the support 2 is provided with a roller 5, and the roller 5 is fixedly connected with the base 4. The roller 5 facilitates the movement of the device by the training personnel. Further, a latch can be arranged on the roller 5, and the latch can be used to stop the roller 5 from moving unnecessarily when the movement is not needed.
