[0043] As attached Figure 1-Figure 3 As shown, this embodiment provides a height-adjustable grid frame, comprising:

[0044] A base assembly 10 is provided on the ground;

[0045] The first support tube 20 is vertically fixed on the base assembly 10;

[0046] The adjusting tube 30 is vertically fixed to the top of the first supporting tube 20 and is arranged coaxially with the first supporting tube 20. The adjusting tube 30 is provided with at least two mutually parallel positioning grooves 31 along its height direction. The positioning grooves 31 are annular grooves, and the height of each positioning groove relative to the ground is the height of the net corresponding to different balls; Figure 2 As shown, in this embodiment, there are two positioning grooves 31 on the adjustment tube 30. The upper positioning groove 31 corresponds to the height of the tennis net, and the lower positioning groove 31 corresponds to the height of the pickle ball net.

[0047] The second support tube 40 is vertically arranged above the adjustment tube 30 and is coaxial with the adjustment tube 30. That is, the first support tube 20, the adjustment tube 30, and the second support tube 40 are coaxially arranged. The height of the top of the second support tube 40 relative to the ground is the height of the net corresponding to another ball game. In this embodiment, the height of the top of the second support tube 40 is the height of the badminton net.

[0048] During use, according to different ball sports, the top two sides of the net are fixed to the positioning grooves 31 of corresponding heights or the top of the second support tube 40. After the net is tightened, the bottom two sides are fixed to the corresponding positions of the first support tube 20, so that the net is fixed in a tightened state.

[0049] Compared with the traditional method of printing scales on the support tubes on both sides, the solution of this embodiment has the characteristics of low labor cost and easy installation. It can at least meet the requirements of the net height for three ball sports: tennis, pickleball, and badminton, realize multiple uses of one net, and is suitable for promotion and use.

[0050] Specifically, the second support tube 40 passes through the regulating tube 30 from top to bottom, and the lower end of the second support tube 40 is fixed to the upper end of the first support tube 20 after passing through the regulating tube 30; for the convenience of connection, the regulating tube 30 has a thin top and thick bottom structure, and the inner diameter of its upper port 32 is smaller than the inner diameter of its lower port 33; the outer diameter of the second support tube 40 is smaller than the inner diameter of the upper port 32 of the regulating tube 30, so that the second support tube 40 can smoothly pass through the interior of the regulating tube 40.

[0051] In order to ensure that the first support tube 20 can be stably connected to the adjustment tube 30 and the second support tube 40, Figure 3 As shown, the inner wall at the lower end 33 of the regulating tube 30 includes a first connecting portion 331 capable of sleeved on the top end of the first support tube 20 and a second connecting portion 332 capable of sleeved on the lower end of the second support tube 40. The first connecting portion 331 is located below the second connecting portion 332.

[0052] The inner diameter of the first connecting portion 331 is adapted to the outer diameter of the first supporting tube 20 so that the first supporting tube 20 is firmly connected to the lower end of the adjusting tube 30;

[0053] The lower end of the second support tube 40 passes through the second connecting portion 332 and enters the first support tube 20. Since the adjusting tube 30 has a thin structure at the top and thick at the bottom, the inner diameter of the second connecting portion 332 is larger than the outer diameter of the second support tube 40. In order to ensure the stable installation of the second support tube 40 in the adjusting tube 30, the second connecting portion 332 is evenly provided with a plurality of strip protrusions 3321 along its circumference. The strip protrusions 3321 extend along the length direction of the adjusting tube 30. The setting of the strip protrusions 3321 is equivalent to reducing the inner diameter of the second connecting portion 332. The outer diameter of the second support tube 40 is larger than the inner diameter of the second connecting portion 332. The second support tube 40 and the second connecting portion 332 become an interference fit. In this embodiment, the second support tube 40 is an elastic tube, which facilitates the second support tube 40 to elastically deform under the interference fit and smoothly pass through the second connecting portion 332.

[0054] Similarly, in order to make the lower end of the second support tube 40 fit tightly with the upper end of the first support tube 20, a strip protrusion (not shown in the figure) is also provided on the inner wall of the upper end of the first support tube 20. The second support tube 40 and the first support tube 20 are also interference fit, and the second support tube 40 undergoes elastic deformation and is tightly connected to the first support tube.

[0055] In order to mark the height of the net for various ball games, a ball image mark is provided above or below the positioning groove 31, such as Figure 2-3As shown, a tennis image logo 311 is provided below the upper positioning groove 31, and a pickleball image logo 312 is provided below the lower positioning groove 31. With the prompts of the tennis image logo 311 and the pickleball image logo 312, the user can fix the top of the net to the corresponding positioning groove 31 as needed to meet various sports needs.

When in use, the connecting member at the top is fixed to the positioning grooves 31 of corresponding heights on the two net frames or the top of the second support tube 40, and the connecting member at the bottom is connected and fixed to the corresponding position of the first support tube 20, so that the ball net body 60 is fixed and tightened. As shown Figure 7 The figure shows the ball net structure of the pickle ball connected to the positioning groove 31 below the adjustment tube 30. Figure 8 The tennis net structure is connected to the positioning groove 31 above the adjustment tube 30. Figure 8 It is a badminton net structure connected to the top end of the second support tube 40 .

[0061] Compared with the traditional method of adding scale printing on both sides of the support tube, it has the characteristics of low labor cost and easy installation. It can meet the height requirements of the net for at least three ball sports, realizing multiple uses of one net and is suitable for promotion and use.

[0062] Users can adjust the net body up and down to the required height according to the ball image logo to meet the net height requirements of different ball sports and fix it, thereby achieving the effect of playing multiple ball sports.
