[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A volleyball spiking training device includes a base 1 and a volleyball body 10. A support rod 2 is fixedly connected to the upper end of the base 1. A scale mark 3 is provided on the front of the support rod 2. T-shaped slide rails 4 are fixedly connected longitudinally on both sides of the support rod 2. A sliding frame 5 is slidably sleeved on the outer side of the T-shaped slide rails 4. A positioning pin 6 is movably inserted into the outer side of the sliding frame 5. A connecting seat 7 is also fixedly connected to the outer side of the sliding frame 5. An installation seat 9 is provided on the outer side of the connecting seat 7. The outer side of the installation seat 9 is movably connected to the volleyball body 10. A connecting rod 8 is fixedly connected to the inner side of the installation seat 9 and inserted into the connecting seat 7. An arc-shaped groove 901 is provided on the outer side of the installation seat 9 and snapped onto the outer side of the volleyball body 10. Magnetic suction pieces 902 that magnetically attract each other are provided on one side of the volleyball body 10 and the inner wall of the arc-shaped groove 901. The surface of the volleyball body 10 on this side is also connected to the inner wall of the arc-shaped groove 901 by a contracting elastic rope 903.

[0022] Based on the above structural design, this device features two sets of T-shaped slide rails 4 on the outer side of the support rod. Each set of T-shaped slide rails 4 is equipped with a volleyball training device, allowing for simultaneous use by two athletes. The volleyball body is connected to the outer side of the connecting seat 9 via an elastic rope 903, enabling it to automatically extend back into place after the volleyball body 10 is hit, eliminating the need for the trainee to run to retrieve the ball. Furthermore, the arc-shaped groove 901 on the outer side of the connecting seat 9, in conjunction with the magnetic plate 901 on the outer side of the volleyball body 10, automatically attracts and secures the volleyball body 10, facilitating continuous training and significantly improving overall portability.

[0023] The support rod 2 has a lamp holder 201 fixedly connected to the top, and lighting lamps 202 are fixedly connected to both sides of the lamp holder 201. This provides good lighting during night training and makes it convenient for trainees to use.

[0024] It should be added that trainees can make highly adaptive adjustments to the sliding frame 5 and its outer structure by observing the scale mark 3 according to their own training needs. Since multiple sets of positioning holes 601 are evenly arranged from top to bottom on the surface of the T-shaped slide rail 4, the inner end of the positioning pin 6 is movably inserted into the positioning hole 601, and the outer end of the positioning pin 6 is fixedly connected to the handle 602, which is connected to the outer wall of the sliding frame 5 through a retractable spring 603. Since different trainees have different heights and different jump heights, we can pull the handle 602 and stretch the spring 603 in advance according to the trainee's own condition, so that the positioning pin 6 disengages from the positioning hole 601 on the outer side of the T-shaped slide rail 4. Then, slide and adjust the height of the outer sliding frame 5 of the T-shaped slide rail 4. After reaching the appropriate height, release the handle 602. Under the elastic contraction force of the spring 603, the positioning pin 6 will be driven to engage in the corresponding positioning hole 601, thus fixing the height of the adjusted sliding frame 5. That is, the height of the sliding frame 5, the externally connected mounting base 9, and the volleyball body 10 are adjusted for the convenience of the trainee.

[0025] The connector 7 has a through-hole interface 701 on its outer side. A locking block is fixedly connected to the inner wall of the interface 701. A rotating sleeve 702 that mates with the interface 701 is also rotatably connected to the outer side of the connector 7. A limiting groove 801 is provided laterally on the outer side of the connecting rod 8. The limiting groove 801 and the locking block are engaged. The surface of the connecting rod 8 near the interface 701 is a smooth surface 802, while the surface of the connecting rod 8 away from the interface 701 is a threaded surface 803. After the connecting rod 8 is inserted into the interface 701, it is threadedly connected to the rotating sleeve 702 through the threaded surface 803 on the outer side. For the installation and subsequent replacement of the volleyball body 10, the connecting rod 8 on the outside of the mounting base 9 is connected to the insertion interface 701 on the outside of the connecting base 7. The smooth surface 802 on the outside of the connecting rod 8 passes through the rotating sleeve 702 and is inserted into the insertion interface 701. The limiting groove 801 on the outside of the connecting rod 9 is engaged with the locking block on the inner wall of the insertion interface 701 until the threaded surface 803 on the outside of the connecting rod 8 is engaged with the rotating sleeve 702. Then, the rotating sleeve 702 is adjusted to rotate and the threaded connecting rod 8 is driven. Under the limiting groove 802 on its outside and the locking block, the connecting rod 8 moves laterally in the connecting base 7 until it is fully inserted into the insertion interface 701. With the help of the threaded structure, the connecting rod 8, the connected connecting base 9, and the volleyball body 10 can be installed. The subsequent disassembly is the same.

[0026] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
