DETAILED DESCRIPTION

[0021] The following will be combined with the attached embodiment of the utility model Figure 1-5 , the technical solutions in the embodiments of the utility model are described in detail. Example 1

[0022] like Figure 1-5 As shown, the utility model is a tennis training device, comprising a net assembly 1 and two support assemblies 2. The net assembly 1 is supported on both sides by the support assemblies 2 and is set up in the center of the court. The net assembly 1 and the two support assemblies 2 are connected by plugging, and the disassembly process is quick and convenient.

[0023] The mesh assembly 1 includes a mesh body 104 , both sides of which are fixedly connected to convex limit blocks 101 . The convex limit blocks 101 are used to be clamped with the support assembly 2 , and the wider part of the convex limit blocks 101 faces outwards.

[0024] The top of the mesh body 104 is fixedly connected with an upper support body 102, a soft rod 103 passes through the interior of the upper support body 102, and is connected to the convex limit block 101 at both ends. The upper support body 102 and the soft rod 103 are used to support the mesh body 104 to prevent the mesh body from becoming soft.

[0025] like Figure 1 and Figure 3 As shown, the fixing foot 4 directly lands on the ground, and the fixing foot 4 protrudes upward to form a fixing rod, which is connected to the supporting assembly 2.

[0026] like Figure 3-5 As shown, the support assembly 2 includes a protective shell assembly 201 located on the outside and a limiting rod assembly 202 located on the inside. The bottom of the protective shell assembly 201 is sleeved on and fixed to the fixed rod of the fixed foot 4, and the limiting rod assembly 202 is rotatably connected to the fixed rod of the fixed foot 4.

[0027] The protective shell assembly 201 includes an outer protective shell 2011 , the top of the outer protective shell 2011 is hollow, and an internet access port 2012 is provided on the outer surface of the outer protective shell 2011 , and the upper end of the internet access port 2012 extends out of the upper wall of the outer protective shell 2011 .

[0028] The bottom of the outer protective shell 2011 is fixedly connected to the bottom support plate 2013, and the middle of the bottom support plate 2013 is concave to form a through hole, which is used to be sleeved on the fixing rod of the fixing foot 4 and fixedly connected thereto.

[0029] The limiting rod assembly 202 includes an inner mounting rod 2021, which is concave inward along the vertical direction to form a convex limiting groove 2022. The end with a smaller opening of the convex limiting groove 2022 extends out of the outer wall of the inner mounting rod 2021. The convex limiting groove 2022 matches the convex limiting block 101 and is plug-in connected, so the installation is quick and convenient.

[0030] The top of the inner mounting rod 2021 is hollow, and its bottom is solid. The middle of the bottom is concave to form a mounting hole for the first bearing 2025. The first bearing 2025 is sleeved on the fixed rod of the fixed foot 4, and its inner wall is fixedly connected to the fixed rod. The outer wall of the first bearing 2025 is fixedly connected to the bottom of the inner mounting rod 2021. Therefore, the limit rod assembly 202 can rotate relative to the protective shell assembly 201.

[0031] The upper surface of the inner mounting rod 2021 is fixedly connected to the screw rod 2023, and the limiting plate 2024 is threadedly connected to the screw rod 2023. The screw rod 2023 is biased to one side to avoid other structures. When the limiting plate 2024 rotates to the inside, its lower surface fits with the upper surface of the inner mounting rod 2021, covering the convex limiting groove 2022, limiting it, and preventing the convex limiting block 101 from slipping.

[0032] When the limiting plate 2024 rotates to the outside, the convex limiting groove 2022 is exposed, so that the convex limiting block 101 can be taken out later, and the mesh assembly 1 can be replaced or stored.

[0033] Furthermore, when the limiting plate 2024 rotates to the inside, due to the eccentricity, the limiting plate 2024 will not completely cover the top of the supporting assembly 2, so that even if the mesh assembly 1 is stored due to bad weather, moisture can be discharged to keep it dry and avoid mold.

[0034] One of the two supporting assemblies 2 is provided with a brake handle 3 on its limit rod assembly 202, and the brake handle 3 is fixedly connected to the top of its screw 2023. Rotating the brake handle 3 can drive the limit rod assembly 202 to rotate, so as to receive the mesh assembly 1 to the outside of the inner mounting rod 2021 and the inside of the outer protective shell 2011. The mesh assembly 1 is wrapped around the inner mounting rod 2021 to prevent the mesh from being damaged by bad weather and extend the service life of the mesh.

[0035] When the net needs to be used, the brake handle 3 is rotated in the opposite direction to release the net assembly 1, and the convex limit block 101 of the net assembly 1 is re-engaged in the corresponding convex limit groove 2022. During this process, the upper support body 102 and the soft rod 103 can assist the net body 104 to unfold quickly and maintain a certain tension.

[0036] There is a gap between the protective shell assembly 201 and the limiting rod assembly 202, and the gap is used to store the mesh assembly 1. The entire storage process is: rotate the limiting plate 2024 of the support assembly 2 without the brake handle 3 to the outside to expose the convex limiting groove 2022, and then take out the convex limiting block 101, rotate the brake handle 3 of the other support assembly 2, and the limiting rod assembly 202 rotates accordingly.

[0037] Since the protective shell assembly 201 and the fixing foot 4 remain stationary as a whole, the mesh assembly 1 enters between the outer protective shell 2011 and the inner mounting rod 2021 from the mesh inlet 2012 and is continuously stored around the inner mounting rod 2021 .

[0038] The height of the convex limiting block 101 and the net body 104 is the same as the height of the net entrance 2012 and the convex limiting groove 2022. The width of the net entrance 2012 is slightly larger than the thickness of the net body 104 and the upper support body 102. The detailed size specifications of the net assembly 1 need to meet the national standard requirements for tennis nets. At the same time, the convex limiting block 101 moves smoothly in the convex limiting groove 2022.

[0039] A method of using the tennis training device of this embodiment is as follows:

[0040] When replacing the mesh, rotate the limiting plate 2024 to make it move upward and shift to one side to expose the convex limiting groove 2022, then take out the convex limiting blocks 101 on both sides of the mesh assembly 1 from the convex limiting groove 2022, and then insert the convex limiting blocks 101 on both sides of the new mesh assembly 1 into the convex limiting grooves 2022 of the two support assemblies 2 respectively, then turn the limiting plate 2024 back and cover the convex limiting groove 2022 to limit it, and complete the quick disassembly and installation of the mesh assembly;

[0041] When it is not needed, the convex limit block 101 on the side where the brake handle 3 is not installed can be taken out from the convex limit groove 2022, and the brake handle 3 can be rotated to receive the mesh assembly 1 to the outside of the inner mounting rod 2021 and the inside of the outer protective shell 2011, so that the mesh assembly 1 is wrapped around the inner mounting rod 2021. When it is needed, the brake handle can be rotated again to release the mesh assembly 1 and re-engage it in the corresponding convex limit groove 2022.

[0042] The above embodiments are only for illustrating the technical idea of ​​the present utility model, and cannot be used to limit the protection scope of the present utility model. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present utility model shall fall within the protection scope of the present utility model.
