Description

Technical Field

[0001] This utility model relates to the field of tennis training equipment technology, specifically a tennis training device. Background Technology

[0002] Tennis is a ball sport, usually played between two singles players or two pairs. When players train individually, a springboard is placed on the opposite court. Players hit the tennis ball onto the springboard on their own court, and the springboard bounces the high-speed tennis ball back to their own court for hitting practice. Because the springboard is fixed to the support frame and the support frame is fixed, the angle cannot be adjusted. Tennis training cannot simulate the variety of returns that are closer to a real match, resulting in mediocre training effects.

[0003] Therefore, improvements can be made to the support structure to enhance the adaptability of the tennis trainer. To this end, we propose a tennis trainer. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a tennis training device that solves the problem of angle adjustment between supports.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tennis training device, comprising a spring plate, with two sets of first supports at the bottom end of the spring plate. A connecting shaft is movably nested on the inner wall of the bottom end of each first support, and a rotating sleeve is movably nested on the outer wall of the connecting shaft on one side of the first support. Two sets of second supports are fixedly connected to the outer wall of the rotating sleeve. A column is fixedly connected to the end of each second support away from the rotating sleeve, and a third support is fixedly connected to the side of the column away from the second supports. Support rods are fixedly connected to the outer walls of the two sets of first supports, and an adjustment component is fixedly connected to the end of each first support away from the connecting shaft.

[0006] Preferably, the adjustment component mainly includes a fixed block, a fixing bolt passing through the inner wall of the fixed block, a movable block nested movably on the outer wall of the fixing bolt on one side of the fixed block, a positioning hole being provided at the contact part between the movable block and the fixing bolt, and a fixing sleeve being threadedly connected to the end of the fixing bolt.

[0007] Preferably, the spring plate is inclined and fits against the support rod.

[0013] This utility model discloses a tennis training device, which has the following beneficial effects:

[0014] 1. This tennis training device involves rotating two sets of fixed sleeves to separate them from two sets of fixed bolts. The two sets of fixed bolts are then inserted into two corresponding positioning holes. Rotating the two sets of fixed sleeves again fixes them to the bolts.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, 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.

[0022] This application provides a tennis training device, including a spring plate 1. Two sets of first supports 2 are provided at the bottom of the spring plate 1. A connecting shaft 3 is movably nested within the inner wall of the bottom of each first support 2. A rotating sleeve 4 is movably nested within the outer wall of the connecting shaft 3 on one side of the first support 2. Two sets of second supports 5 are fixedly connected to the outer wall of the rotating sleeve 4. A column 6 is fixedly connected to the end of each second support 5 away from the rotating sleeve 4. A third support 7 is fixedly connected to the side of the column 6 away from the second support 5. Support rods 8 are fixedly connected to the outer walls of the two sets of first supports 2. An adjustment component is fixedly connected to the end of each first support 2 away from the connecting shaft 3. This arrangement of the spring plate 1, the two sets of first supports 2, the connecting shaft 3, the rotating sleeve 4, the two sets of second supports 5, the two sets of columns 6, the two sets of third supports 7, and the support rods 8 allows the spring plate 1 to bounce a high-speed tennis ball, simulating a real-person match and achieving the purpose of tennis training.

[0023] Furthermore, the adjustment component mainly includes a fixed block 9, with a fixing bolt 10 penetrating through the inner wall of the fixed block 9. A movable block 11 is movably nested on the outer wall of the fixing bolt 10 on one side of the fixed block 9. A positioning hole 12 is provided at the contact part between the movable block 11 and the fixing bolt 10. A fixing sleeve 13 is threadedly connected to the end of the fixing bolt 10, which facilitates the rotation of the two sets of fixing sleeves 13 to separate the two sets of fixing sleeves 13 from the two sets of fixing bolts 10. The two sets of fixing bolts 10 are then inserted into the other two sets of corresponding positioning holes 12. The two sets of fixing sleeves 13 are rotated to fix the two sets of fixing sleeves 13 to the two sets of fixing bolts 10. With the arrangement of the two sets of fixed blocks 9 and the two sets of movable blocks 11, the angle adjustment of the spring plate 1 is realized.

[0024] Furthermore, the spring plate 1 is set at an angle, and the spring plate 1 is in contact with the support rod 8, which is conducive to the spring plate 1 rebounding the high-speed tennis ball.

[0025] Furthermore, the outer wall of the fixing block 9 is provided with a movable groove, which facilitates the movement of the fixing bolt 10 along the movable groove on the outer wall of the fixing block 9.

[0026] Furthermore, three sets of positioning holes 12 are provided, and the three sets of positioning holes 12 are equally spaced about the outer wall of the movable block 11, which is conducive to the fixing bolt 10 being embedded in different positioning holes 12 to realize the angle adjustment of the spring plate 1.

[0027] Furthermore, the bottom end of the movable block 11 is fixedly connected to the bottom end of the column 6, which is beneficial for fixing the movable block 11.

[0028] Furthermore, a chassis 14 is fixedly connected to the outer wall of the third support 7. Two sets of counterweights 15 are attached to the top of the chassis 14. A limit rod 16 is fixedly connected to the center of the top of the chassis 14. This helps to increase the friction between the chassis 14 and the ground under the setting of the two sets of counterweights 15 and the limit rod 16, thus preventing the tennis trainer from shifting.

[0029] Furthermore, the bottom of the chassis 14 is in contact with the ground, which facilitates contact between the bottom of the chassis 14 and the ground, increasing the friction between the tennis training device and the ground.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] Working principle: Rotate the two sets of fixing sleeves 13 to separate the two sets of fixing sleeves 13 from the two sets of fixing bolts 10, and insert the two sets of fixing bolts 10 into the other two sets of corresponding positioning holes 12. Rotate the two sets of fixing sleeves 13 to fix the two sets of fixing sleeves 13 to the two sets of fixing bolts 10. With the setting of the two sets of fixing blocks 9 and the two sets of movable blocks 11, the angles of the two sets of first brackets 2 and the two sets of second brackets 5 are adjusted, so that the angle of the spring plate 1 changes.

[0032] With the setup of two sets of first supports 2, connecting shaft 3, rotating sleeve 4, two sets of second supports 5, two sets of uprights 6, two sets of third supports 7 and support rods 8, the spring plate 1 is supported. With the setup of chassis 14, two sets of counterweights 15 and limiting rods 16, the friction between the tennis trainer and the ground is increased. When the player hits the tennis ball on the spring plate 1, the spring plate 1 bounces the high-speed tennis ball, which can simulate a variety of returns that are closer to real matches in tennis training.
