[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 The present invention will be described in detail with specific embodiments.

[0026] like Figures 1 to 5 As shown, the present invention provides a tennis hitting simulation training device, including a fixed rod 1, with fixed blocks 11 fixedly connected to both ends of the fixed rod 1. A support frame 2 is fixedly connected to the side wall of the fixed rod 1, and a pair of guide rods 3 are fixedly connected to the top of the support frame 2. Each guide rod 3 is connected to a limit rod 4, and the space enclosed by the limit rod 4 and the guide rod 3 is a guide groove 31.

[0027] A rubber wheel 5 is provided between a pair of guide rods 3. Rotating rods 51 are fixedly connected to both sides of the axis of the rubber wheel 5. The rotating rods 51 are placed in the guide groove 31. The rotating rods 51 can move in the guide groove 31 and can also rotate during the movement.

[0028] In use, the fixing block 11 is placed tightly against the column 6 in the playground or training field. A fixing strap 7 is provided between the fixing block 11 and the column 6. One end of the fixing strap 7 is fixedly connected to a strap tensioner 71. The strap tensioner 71 is existing technology and will not be described in detail here. The fixing strap 7 is tightened by the strap tensioner 71, thereby fixing the fixing block 11 to the column 6.

[0029] Students hold tennis rackets and strike the rubber wheel 5 from bottom to top. As the racket strikes the rubber wheel 5, the rubber wheel 5 rotates from one side of the guide rod 3 to the other side of the guide rod 3. This is used to simulate hitting a topspin tennis ball. During the training, there is no need to frequently pick up the tennis ball, which greatly speeds up the teaching progress and improves the teaching quality. Students can simulate hitting a tennis ball by striking the rubber wheel 5.

[0030] The guide rod 3 has a locking groove 32 on both sides. The two ends of the limiting rod 4 are respectively locked into the locking groove 32. The limiting rod 4 can undergo elastic deformation. When locking the limiting rod 4 into the locking groove 32, first lock one end of the limiting rod 4 into the locking groove 32, then move the other end of the limiting rod 4 to make the limiting rod 4 undergo elastic deformation. After the end of the limiting rod 4 is aligned with the locking groove 32, release the limiting rod 4. After the limiting rod 4 returns to its original deformation, the end of the limiting rod 4 is tightly locked into the locking groove 32.

[0031] Each guide rod 3 is threaded with two fastening bolts 33. The two fastening bolts 33 are placed near the two ends of the guide rod 3. The fastening bolts 33 abut against the limiting rod 4. The fastening bolts 33 increase the stability of the engagement between the limiting rod 4 and the locking groove 32 and reduce the possibility of the limiting rod 4 separating from the locking groove 32.

[0032] A first anti-slip pad 331 is fixedly connected to the end of the fastening bolt 33 near the limit rod 4. The first anti-slip pad 331 contacts the limit rod 4. When the fastening bolt 33 is pressed against the limit rod 4, the first anti-slip pad 331 contacts the limit rod 4. The first anti-slip pad 331 increases the stability of the fastening bolt 33 pressing against the limit rod 4.

[0033] When the surface of the rubber wheel 5 is severely worn after long-term use and needs to be replaced, separate the fastening bolt 33 from the limiting rod 4 to release the restriction on the limiting rod 4. Move the limiting rod 4 to separate it from the locking groove 32. The limiting rod 4 will then release the restriction on the rotating rod 51. Replace the rubber wheel 5 with a new one. Then, place the rotating rod 51 between the limiting rod 4 and the guide rod 3, and lock the limiting rod 4 into the locking groove 32. Tighten the fastening bolt 33 to press the limiting rod 4 against the ground.

[0034] The bottom of the support frame 2 is connected to a support component 8, which is used to support the support frame 2, improve the stability of the fixing strap 7 fixing the fixing block 11 to the column 6 during the impact simulation training, and reduce the possibility of the support frame 2 sliding down.

[0035] The support assembly 8 includes a support rod 81 fixedly connected to the bottom of the support frame 2. The lower surface of the support rod 81 is provided with a threaded hole 811 facing upward. The support rod 81 is connected to a threaded rod 82, which is threadedly connected to the threaded hole 811. The lower end of the threaded rod 82 is fixedly connected to a support plate 83, and the lower surface of the support plate 83 is fixedly connected to a second anti-slip pad 831.

[0036] After the fixing strap 7 secures the fixing block 11 to the column 6, the threaded rod 82 is rotated to move the support plate 83 downwards until the second anti-slip pad 831 is pressed against the ground. The threaded rod 82 and the support rod 81 support the support frame 2, increasing the stability of the fixing strap 7 in securing the fixing block 11 to the column 6 and reducing the possibility of the support frame 2 sliding down. The second anti-slip pad 831 contacts the ground, reducing the possibility of the support plate 83 sliding and further improving stability.

[0037] The implementation principle of the tennis hitting simulation training device provided by this utility model is as follows: the student holds a tennis racket and hits the rubber wheel 5 from bottom to top. During the process of the tennis racket hitting the rubber wheel 5, the rubber wheel 5 rotates from one side of the guide rod 3 to the other side of the guide rod 3, which is used for the simulation training of hitting the topspin ball of the tennis ball. During the training process, there is no need to pick up the tennis ball frequently, which greatly speeds up the teaching progress and has the effect of improving the teaching quality. Students can simulate the process of hitting a tennis ball by hitting the rubber wheel 5.

[0038] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention.
