Therefore, the counterweight assemblies 300 located in different partition cylinders 4 are arranged in the flexible placement cylinder 13. The weight is also inconsistent, depending on the weight of the counterweight 15 placed in the flexible placement cylinder 13. Using multiple separation cylinders 4 can classify and place flexible placement cylinders 13 of various weights. After accurately adding the weight of the counterweight 15 to the multiple flexible placement cylinders 13, it is convenient for training personnel to match the weights and select the corresponding multiple flexible placement cylinders 13. Two flexible placement cylinders 13 are used as a group because if a longer flexible placement cylinder 13 is used, it is easy for the flexible placement cylinder 13 to be inconvenient to fully enter the storage chute 9, and it is inconvenient to reset from the storage chute 9 to the separation cylinder 4.

[0029] It also includes a mounting platform 16, the bottom of which is connected to a plurality of sliding slots 17, which are connected to the top of the receiving box 3, and the sliding slots 17 correspond to the counterweight components 300 one by one, wherein both sides of the sliding slots 17 are provided with through slots, and when the corresponding flexible placement cylinder 13 needs to be moved into the storage slide groove 9, the ferrous sheet 19 is made to slide in the sliding slot 17, and the moving path of the ferrous sheet 19 is restricted, so that the ferrous sheet 19 can only fall and rise vertically, so as to facilitate the ferrous sheet 19 to be magnetically connected to the electromagnetic seat 18 again, and to restrict the reset position of the flexible placement cylinder 13; Among them, multiple counterweight assemblies 300 are divided into two groups, and a magnetic suspension mechanism 400 is arranged between the multiple counterweight assemblies 300 located in the same group and the top of the containing box 3. The magnetic suspension mechanism 400 includes an electromagnetic seat 18 and a ferrous sheet 19. Multiple electromagnetic seats 18 are arranged at the bottom of the mounting platform 16. The electromagnetic seats 18 are located in the sliding groove 17. Each electromagnetic seat 18 is magnetically connected to a ferrous sheet 19. A suspension rope 20 is arranged between the ferrous sheet 19 and the flexible placement cylinder 13 located on the upper side. The electromagnetic seat 18 is a common electromagnet device in the prior art. By supplying power to the electromagnetic seat 18, the electromagnetic seat 18 generates magnetism to magnetically adsorb the ferrous sheet 19. When the flexible placement cylinder 13 needs to fall into the receiving chute 9, the corresponding electromagnetic seat 18 can be closed to make the ferrous sheet 19 fall in the sliding groove 17.

[0030] The top of the accommodating box 3 is provided with an integral lifting mechanism 500 for the multiple magnetic suspension mechanisms 400. The integral lifting mechanism 500 is used to reset the counterweight assembly 300. The integral lifting mechanism 500 includes a support ring sleeve 21, a connecting piece 22 and a connecting piece 23. Each sliding groove 17 is slidably connected with a support ring sleeve 21.

A plurality of support ring sleeves 21 are fixedly connected, and a lifting assembly is arranged between the connecting piece 23 and the mounting platform 16. First, the plurality of support ring sleeves 21 are all moved to the bottom of the sliding groove body 17. During the falling process of the iron sheet 19, the iron sheet 19 will fall onto the elastic buffer ring sleeve 27. The elastic buffer ring sleeve 27 can effectively buffer the impact force caused by the falling of the iron sheet 19. The iron sheet 19 stops falling after contacting the elastic buffer ring sleeve 27, and the hanging rope 20 will enter the partition cylinder 4. The hanging rope 20 has a certain length, so that during the process of the storage slide 9 driving the flexible placement cylinder 13 to move, the hanging rope 20 will not pull the flexible placement cylinder 13. The lifting assembly includes a lifting slot frame 24, a transmission screw 25 and a drive motor 26. The lifting slot frame 24 is fixedly connected to the mounting platform 16.

A drive motor 26 is arranged on the lifting slot frame 24. The output end of the drive motor 26 is fixedly connected to the transmission screw 25. When it is necessary to readjust the number of flexible placement cylinders 13 in the storage slide 9, the drive motor 26 is started to drive the transmission screw 25 to rotate, so that the connecting member 23 moves longitudinally in the lifting slot frame 24, and under the action of the connecting member 23 and multiple connecting pieces 22, the multiple support ring sleeves 21 rise in the multiple sliding slots 17, so that the fallen iron sheet 19 is moved back into the range of the electromagnetic seat 18, and the flexible placement cylinder 13 originally located in the storage slide 9 returns to the partition cylinder 4. At this time, the trainee selects the flexible placement cylinder 13 of the corresponding weight to continue to move into the storage slide 9.

[0031] Working principle of this professional abdominal training device for sports and fitness: First, the driving motor 26 is started by controlling the operating table 33, and the driving motor 26 drives the transmission screw 25 to rotate, so that the connecting member 23 moves longitudinally in the lifting slot frame 24. Under the action of the connecting member 23 and the multiple connecting pieces 22, the multiple supporting ring sleeves 21 move to the bottom of the multiple sliding slots 17. The trainee sits on the training chair 1 and selects to close the corresponding electromagnetic seat 18 by controlling the operating table 33, and releases the magnetic connection between the corresponding electromagnetic seat 18 and the ferrous sheet 19, so that the ferrous sheet 19 falls in the sliding slot 17. The ferrous sheet 19 stops falling after contacting the elastic buffer ring sleeve 27, and the flexible placement cylinder 13 enters the storage slide 9; The trainee holds the holding tube with both hands and performs crunch-like exercise training on the training seat 1. The holding tube, the height adjustment structure and the sliding seat 7 rotate together along the center point of the rotating ring sleeve 6 to assist the trainee in performing crunch-like abdominal training. The guide rope 12 enters the fixed cylinder 5 through the wire entry hole. During the movement of the sliding seat 7, the guide rope 12 is pulled to move in the fixed cylinder 5. The other end of the guide rope 12 pulls the storage chute 9 to move in the sliding box 2, so that the trainee can perform abdominal training. When it is necessary to readjust the number of flexible placement cylinders 13 in the storage chute 9, the drive motor 26 is started to drive the transmission screw 25 to rotate, so that the connecting member 23 moves longitudinally in the lifting slot frame 24, and under the action of the connecting member 23 and multiple connecting plates 22, the multiple support ring sleeves 21 rise in the multiple sliding slots 17, so that the fallen iron plates 19 are moved back into the range of the electromagnetic seat 18, and the flexible placement cylinder 13 originally located in the storage chute 9 returns to the partition cylinder 4. At this time, the trainee selects the flexible placement cylinder 13 of the corresponding weight to continue moving it into the storage chute 9.
