[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] As attached Figure 1-4 As shown, the utility model discloses a badminton net post that can be freely combined and used, including a base plate 1, a counterweight block 2, a counterweight plate 3 and a column 4, the counterweight plate 3 is installed on the bottom surface of the base plate 1, the counterweight block 2 is installed on one end of the top surface of the base plate 1, and the column 4 is fixedly installed on the other end of the top surface of the base plate 1.

[0024] A raised portion protruding upward from the surface of the substrate 1 is provided at the other end of the substrate 1, and the counterweight 2 is installed on the raised portion, and a smooth transition is adopted between the counterweight 2 and the substrate 1. A boss 10 for positioning is provided in the middle of the raised portion, and a groove matching the boss 10 is provided on the counterweight 2. After the counterweight 2 and the boss 10 are buckled together, the two are fixedly connected by bolts.

[0025] Preferably, the base plate 1 and the counterweight block 2 are connected in a detachable manner, a stepped hole A8 is opened on the bottom surface of the base plate 1, and a threaded hole A9 corresponding to the stepped hole A8 is opened on the counterweight block 2. The bolt passes through the stepped hole A8 from bottom to top and cooperates with the threaded hole A9 to fix the base plate 1 and the counterweight block 2 together.

[0026] The base plate 1 and the counterweight plate 3 also adopt a detachable connection method. A stepped hole B is provided on the bottom surface of the counterweight plate 3, and a threaded hole B corresponding to the stepped hole B is provided on the base plate 1. The bolt passes through the stepped hole B from bottom to top and is connected to the threaded hole B, thereby fixing the base plate 1 and the counterweight plate 3 together.

[0027] The counterweight block 2 and the counterweight plate 3 are independently connected to the base plate 1, and can be independently disassembled and assembled and freely combined according to actual needs. Four different counterweights can be formed, namely, a single base plate 1, base plate 1 + counterweight block 2, base plate 1 + counterweight plate 3, and base plate 1 + counterweight block 2 + counterweight plate 3, to meet a variety of different usage requirements.

[0028] As a further improvement of the present invention, the side of the base plate 1 close to the counterweight block 2 is an inclined surface, which gradually inclines outward from bottom to top and can be in a flat form or have a certain curvature. A walking wheel 6 is installed on the inclined surface through a rotating shaft 7, and the end faces of the counterweight block 2 and the counterweight plate 3 correspond to the side face of the base plate 1 and both adopt a smooth transition method.

[0029] At the same time, the counterweight plate 3 is located at the bottom of one side close to the counterweight block 2, and a curved transition plane is formed between the side and the ground, and the projection of the center of gravity of the counterweight block 2 on the horizontal plane is located outside the starting point of the lower end of the curved transition plane (that is, the right side position shown in 3), as shown in FIG. Figure 3 As shown by the two dotted lines, the end of the base plate 1 and the counterweight 2 are in a state similar to being lifted. Compared with the traditional form of being completely in contact with the ground, this structure makes the net post as a whole tend to deflect to the right. Under the condition of the same weight of the counterweight 2, it can meet the use requirements of a heavier net. Using a smaller counterweight can meet the standards of the Badminton World Federation and related standards, which is more conducive to movement.

[0030] As a further improvement of the utility model, the column 4 is inclined toward the side close to the counterweight 2. After being pulled by the net, the column 4 is deformed toward the side away from the counterweight 2 to be in a nearly upright state. This can also offset part of the pulling force, further reduce the demand for counterweights, and reduce the overall weight.

[0031] The utility model adopts a counterweight block 2 and a counterweight plate 3 structure that can be independently disassembled and assembled, and can be freely combined and used according to the actual use environment, which can meet the use environment of a variety of different counterweight requirements and has a wider range of use. At the same time, the counterweight block 2 is located at the end away from the column 4, and the counterweight as a whole adopts a rearward center of gravity design. The center of gravity of the assembly formed by the base plate 1, the counterweight block 2, and the counterweight plate 3 is located on the side close to the counterweight block 2, and an arc-shaped smooth transition form is formed between the side of the counterweight plate 3 away from the column 4 and the ground, so that the counterweight block 2 is formed in a state of being too high. In the use state, the assembly has a tendency to deflect along the arc, which can further reduce the overall demand for the counterweight weight, and meet the installation requirements of a larger specification of the net in the case of a smaller counterweight.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
