[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a volleyball blocking training device. (Refer to...) Figure 1 and Figure 6 A volleyball blocking training device includes a support column 1, a weight block 3 fixedly connected to the bottom of the support column 1, a telescopic column 8 movably connected to the inner cavity of the support column 1, and an adjustment mechanism 2 provided at the top of the telescopic column 8.

[0026] The adjustment mechanism 2 includes an adjustment cylinder 21. The bottom of the adjustment cylinder 21 is fixedly connected to the top of the telescopic column 8. There are two adjustment cylinders 21, and the net body 4 is installed between the two adjustment cylinders 21. A smooth rod 25 is rotatably connected to the inner cavity of the adjustment cylinder 21. A rotating cylinder 212 is fixedly connected to the surface of the smooth rod 25. An adjustment rod 23 is fixedly connected to the top and bottom of the surface of the rotating cylinder 212. One side of the adjustment rod 23 extends through the surface of the adjustment cylinder 21 and is fixedly connected to a hanging rod 24. The net body 4 is hung on the surface of the hanging rod 24.

[0027] Reference Figure 4 and Figure 5 The top of the smooth rod 25 extends to the top of the adjusting cylinder 21 and is provided with a positioning plate 211. A connecting block 29 is fixedly connected to the top of the positioning plate 211, and a rotating plate 210 is fixedly connected to the top of the connecting block 29. A fixing ring 28 is installed on the surface of the positioning plate 211, and the bottom of the fixing ring 28 is fixed to the top of the adjusting cylinder 21. Through the setting of the connecting block 29, the rotating plate 210 and the positioning plate 211 can be connected. Then, when the rotating plate 210 is rotated, the positioning plate 211 can be rotated together, thereby facilitating the adjustment of the position of the smooth rod 25.

[0028] Reference Figure 6 The surface of the positioning disk 211 is provided with multiple slots, and the inner ring of the fixing ring 28 is a conical structure. The positioning disk 211 and the fixing ring 28 are connected by a snap-fit. Through the slots on the surface of the positioning disk 211 and the conical block of the inner ring of the fixing ring 28, the positioning disk 211 can be fitted into the inner ring of the fixing ring 28, thereby enabling the positioning disk 211 to be positioned after rotation.

[0029] Reference Figure 6 The inner cavity of the smooth rod 25 is provided with a sliding groove 26, and a sliding column 27 is inserted into the sliding groove 26. The top of the sliding column 27 is fixedly connected to the bottom of the positioning plate 211. Through the setting of the sliding groove 26, its side is a semi-circular groove that matches the semi-circular protrusion on the surface of the sliding column 27, so that the sliding column 27 can not only be pulled up and down inside the smooth rod 25 to adjust the position of the positioning plate 211, but also ensure that the sliding column 27 can smoothly drive the smooth rod 25 to rotate.

[0030] Reference Figure 4 The top and bottom of the surface of the adjusting cylinder 21 are provided with arc-shaped grooves 22. The diameter of the arc-shaped grooves 22 is larger than the diameter of the adjusting rod 23, and the interior of the arc-shaped grooves 22 is slidably connected to the surface of the adjusting rod 23. By setting the arc-shaped grooves 22, the rotation position of the adjusting rod 23 is limited, preventing the adjusting rod 23 from deviating when rotating inside the adjusting cylinder 21.

[0031] Reference Figure 2 A support rod 5 is fixedly connected to the bottom of the inner cavity of the support column 1. The top of the support rod 5 is movably connected to the bottom of the telescopic column 8. A groove 6 is provided on the inner wall of the support column 1. A pulley 7 is rotatably connected inside the groove 6. The surface of the pulley 7 is movably connected to the surface of the telescopic column 8. The support rod 5 provides support for the bottom of the telescopic column 8, thereby preventing the telescopic column 8 from directly extending into the interior of the support column 1. At the same time, the pulley 7 reduces the friction between the telescopic column 8 and the support column 1, thereby facilitating the adjustment of the position of the telescopic column 8.

[0032] Reference Figure 2 and Figure 3 A side groove 9 is provided on one side of the inner wall of the support column 1. An adjusting stud 11 is fixedly connected to the bottom of the surface of the telescopic column 8. One side of the adjusting stud 11 extends through to one side of the side groove 9 and is threadedly connected to a locking nut 10. One side of the locking nut 10 is tightly fitted into the interior of the side groove 9. The side groove 9 has the same cross-sectional area as the diameter of the adjusting stud 11, which guides the position of the adjusting stud 11 after it moves upward. At the same time, the locking nut 10 moves to one side of the side groove 9 under the threaded connection between the locking nut 10 and the adjusting stud 11 until the locking nut 10 is tightly fitted into the surface of the side groove 9, thereby enabling the positioning of the adjusting stud 11 after adjustment.

[0033] Working principle: First, pull the adjusting cylinder 21 upwards. The movement of the adjusting cylinder 21 causes the telescopic column 8 to slide inside the supporting column 1. At this time, the pulley 7 rotates under force, thereby reducing the friction between the telescopic column 8 and the supporting column 1. The movement of the telescopic column 8 causes the adjusting stud 11 to slide inside the side groove 9. When the telescopic column 8 extends from the supporting column 1 to the required position, the locking nut 10 is threadedly connected to the adjusting stud 11. At this time, the locking nut 10 moves to one side of the side groove 9 until it is tightly fitted to one side of the side groove 9, thus fixing the length of the telescopic column 8 extending from the supporting column 1. Then, the net body 4 is hung on the surface of the hanging rod 24. When the net body 4 becomes loose, the rotating disc 21 is manually operated. Pull the connecting block 29 upwards. The movement of the connecting block 29 causes the positioning plate 211 to disengage from the inside of the fixed ring 28. The movement of the positioning plate 211 causes the sliding column 27 to move. The sliding column 27 slides inside the sliding groove 26 without disengaging from the sliding groove 26. Then rotate the rotating disk 210. The rotating disk 210 causes the positioning plate 211 to rotate. The positioning plate 211 causes the sliding column 27 and the smooth rod 25 to rotate. The rotation of the smooth rod 25 causes the rotating cylinder 212 to rotate. The rotation of the rotating cylinder 212 causes the adjusting rod 23 to slide inside the arc groove 22 until the net body 4 is in a taut state. Then press the rotating disk 210 downwards so that the positioning plate 211 is locked into the inner ring of the fixed ring 28 again. The position after rotation can be positioned.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
