[0001] The utility model relates to the technical field of sports tools, in particular to an automatically recoverable juggling training structure. Background Art

[0002] Juggling is an indispensable action in volleyball. Whether the juggling action is in place is directly related to the level of the athlete's volleyball technique. Therefore, in order to improve the athlete's juggling technique, it is necessary to adopt a juggling training structure to provide the athlete with juggling training. However, during the use of the existing juggling training structure, in order to facilitate the recovery of the dropped volleyball, an interception net is usually used to intercept the volleyball, and the volleyball is guided to a specific position for recovery. However, after long-term use, the interception net used for recovery will inevitably be partially damaged due to the impact of the volleyball or other unexpected situations. The damaged interception net will greatly reduce the interception effect of the volleyball, and it is easy for the volleyball to be unable to be recovered. In addition, it is relatively troublesome to manually sew or replace the interception net. For this reason, the utility model improves a juggling training device that can quickly replace the interception net. Summary of the invention

[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Please refer to Figures 1 to 6 :

[0028] Embodiment 1:

[0029] The utility model proposes an automatically recoverable ball juggling training structure, comprising: a ball juggling board 1, the bottom of which is a rectangular structure and is fixedly mounted with a supporting base 9 by bolts; a mounting groove 2 is provided at the top of the rear side of the ball juggling board 1; a transparent window 3 is provided at the front end of the mounting groove 2; the transparent window 3 is made of transparent plastic material; a switching upper roller 4 with a cylindrical structure is rotatably mounted at the top inner end of the mounting groove 2; a switching lower roller 5 with a cylindrical structure is rotatably mounted at the bottom inner end of the mounting groove 2; a friction wheel 6 is fixedly mounted at the right end of the switching lower roller 5; a switching belt 7 is tensioned and mounted on the switching upper roller 4 and the switching lower roller 5.

[0030] When the athlete rotates the friction wheel 6, the friction wheel 6 rotates with the switching lower roller 5, and the switching lower roller 5 moves with the switching belt 7 during rotation, so that the switching belt 7 changes the positions of multiple juggling bull's eyes 8 through movement, so that the juggling bull's eyes 8 of the diameter required by the operator correspond to the transparent window 3, so that the juggling bull's eyes 8 of appropriate sizes can be provided for athletes with different needs.

[0031] Embodiment 2, on the basis of embodiment 1, a plurality of circular juggling bull's eyes 8 are printed on the outer wall of the switching belt 7, and the diameter of each juggling bull's eye 8 is different; a recovery bracket 10 is fixedly installed on the front side of the juggling spring board 1; volleyball interception side nets 11 are installed on the left and right sides of the recovery bracket 10; a cylindrical unwinding replacement roller 12 is rotatably installed on the bottom end of the recovery bracket 10; a cylindrical winding replacement roller 13 is rotatably installed on the front end of the recovery bracket 10.

[0032] The athlete uses the action of juggling to hit the volleyball towards the juggling target 8 behind the transparent window 3, so that the volleyball touches the transparent window 3 and bounces back to the vicinity of the athlete, so that the athlete receives the volleyball and hits it towards the juggling target 8 for a second time. The juggling training for the athlete is realized in this cycle. If the athlete fails to use enough force to hit the volleyball towards the transparent window 3 or the juggling rebound board 1 due to a juggling error, the volleyball will fall on the volleyball interception net 15 under the action of inertia, so that the volleyball interception net 15 cooperates with the recovery bracket 10 and the volleyball interception side net 11 to intercept and recover the fallen volleyball.

[0033] Embodiment 3, on the basis of embodiment 2, a self-locking worm gear 14 is fixedly installed on the left end of the winding replacement roller 13; a volleyball interception net 15 is wound together on the winding replacement roller 13 and the unwinding replacement roller 12; the volleyball interception net 15 is located between the two volleyball interception side nets 11; a support member 16 is fixedly installed on the left side of the top of the recovery bracket 10; a self-locking worm 17 is rotatably installed on the front end of the support member 16; the self-locking worm 17 is connected with the self-locking worm gear 14; an operating handwheel 18 is fixedly installed on the front end of the self-locking worm 17.

[0034] In the event of partial damage on the volleyball intercepting net 15, it is only necessary to rotate the operating hand wheel 18 to rotate it with the self-locking worm 17. At this time, the self-locking worm 17 will rotate with the winding replacement roller 13 under the action of the cooperation and connection with the self-locking worm gear 14, so that the winding replacement roller 13 will rewind the volleyball intercepting net 15 through rotation, and the unwinding replacement roller 12 will also loosen the volleyball intercepting net 15, so that the damaged part of the volleyball intercepting net 15 can be rolled up by the winding replacement roller 13, and at the same time, the complete volleyball intercepting net 15 will replace the damaged volleyball intercepting net 15, so as to continue to intercept and recover the volleyball.

[0035] The working principle of this embodiment:

[0036] Before the juggling training, the athlete first rotates the friction wheel 6 to make the friction wheel 6 rotate with the switching lower roller 5, and the switching lower roller 5 will move with the switching belt 7 when rotating, so that the switching belt 7 can change the positions of multiple juggling bullseyes 8 through movement, so that the juggling bullseye 8 of the diameter required by the operator corresponds to the transparent window 3, so that the juggling bullseye 8 of the appropriate size can be provided for athletes with different needs. After the adjustment is completed, the athlete uses the juggling action to hit the volleyball towards the juggling bullseye 8 behind the transparent window 3, so that the volleyball touches the transparent window 3 and bounces back to the vicinity of the athlete, so that the athlete receives the volleyball and hits the volleyball towards the juggling bullseye 8 for the second time. This cycle realizes the juggling training for the athlete. If the athlete fails to use enough force to hit the volleyball towards the transparent window 3 or the juggling rebound board 1 due to a juggling error, the volleyball The ball will fall on the volleyball interception net 15 under the action of inertia, so that the volleyball interception net 15 cooperates with the recovery bracket 10 and the volleyball interception side net 11 to intercept and recover the fallen volleyball. When the volleyball interception net 15 is partially damaged, the hand wheel 18 is rotated to rotate with the self-locking worm 17. At this time, the self-locking worm 17 will rotate with the winding replacement roller 13 under the action of the cooperation and connection with the self-locking worm gear 14, so that the winding replacement roller 13 can rewind the volleyball interception net 15 through rotation, and at the same time, the unwinding replacement roller 12 will also loosen the volleyball interception net 15, so that the damaged part of the volleyball interception net 15 can be rolled up by the winding replacement roller 13, and at the same time, the complete volleyball interception net 15 will replace the damaged volleyball interception net 15, so as to continue to intercept and recover the volleyball.
