Background

The information disclosed in this background of the invention is only for enhancement of understanding of the general background of the invention and is not necessarily to be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

The pliability refers to the range of motion of each joint and the ability of the soft tissues such as muscles, tendons and ligaments to stretch. For the dancer, the good flexibility of each part of the body is the basic guarantee for finishing the dancing action, and the flexibility of the shoulder, the waist, the hip, the leg and other parts of the dancer is higher in requirement, because the parts are the parts with large body movement in the dancing process. Poor flexibility not only makes it difficult to master the dance movements well, but also limits the exertion of force, speed and coordination, and if the dance movements are forced to be performed, muscles, ligaments and the like are easily damaged.

Therefore, the dancer should train both the soft openness and flexibility of the body. Passive training is one of the important ways of training that is flexible. At present, passive training mainly depends on assistance of teachers or companions, and training is insufficient due to the fact that the assistors are difficult to continuously accompany training. Therefore, there is a need to develop devices suitable for use in physical flexibility training.

The gear groove body and the gear sealing cover with the special structure not only realize the restraint of the first gear, but also ensure the normal rotation of the first gear, thereby driving the screw rod, enabling the screw rod to reciprocate up and down, assisting a trainer to carry out the flexible training of the waist, and the gear groove body also has the function of stabilizing the screw rod.

The gear cover 9 is the same as the gear groove body 8 in structure, and the gear cover 9 is detachably connected to the gear groove body 8 through bolts so as to facilitate installation and detachment of the first gear 10. The first gear 10 is horizontally installed in the circular gear groove 18, the balls 11 are arranged in the accommodating cavities formed by the second groove 20 and the third groove 22 on the lower surface of the first gear 9 and the accommodating cavities formed by the third groove 22 on the upper surface of the first gear 9 and the second groove 20 of the gear cover 9, and the first gear 9 is supported above the bottom surface of the circular gear groove 18 by the balls 11.

For the screw rod 12, the lower end of the screw rod passes through the threaded hole 23 in the center of the first gear 9 and the support plate 7 and then extends to the lower part of the support plate 7, the screw rod 12 is in threaded connection with the threaded hole 23, and the upper end of the screw rod 12 extends to the upper part of the gear cover 9.

The driving motor 13 is fixed on the upper surface of the supporting plate 7 and located on one side of the gear groove body 8, the second gear 14 is horizontally arranged and fixedly connected to a motor shaft of the driving motor 13, and the second gear 14 penetrates through the opening groove 21 and then is meshed with the first gear 9. The holding part 15 is detachably connected to the lower end face of the screw rod 12, the control button 16 is arranged on the holding part 15, and the elevator 3 and the driving motor 13 are both connected with the control button 16.

With continued reference to fig. 1, in another embodiment, a first flexible layer 24 is attached to the surface of the first recess 17, and the first flexible layer 24 is a sponge layer, and the first flexible layer mainly functions to protect the fixed part of the leg of the trainer and keep the trainer comfortable during the training.

With continued reference to fig. 1, in another embodiment, the holding portion 15 is composed of a connecting cylinder 25 and two cross bars 26, wherein the connecting cylinder 25 is detachably connected to the screw rod 12 through a bolt, the two cross bars 26 are horizontally connected to two sides of the connecting cylinder 25 respectively, the control button 16 is arranged on the connecting cylinder 25, and the cross bars 26 can be conveniently held by a practicer during training and further perform regular up-and-down movement along with the screw rod 12.

With continued reference to fig. 1, in another embodiment, a second flexible layer 27 is disposed on the outer surface of the cross bar 26, and the second flexible layer 27 is made of rubber, which can increase the friction between the palm of the trainer and the cross bar 26 to prevent slipping.

With continued reference to fig. 1, in another embodiment, the external threads on the surface of the screw rod 12 are only distributed on the upper portion of the screw rod 12, and since the screw rod 12 does not need to move up and down greatly, only the surface of the screw rod within the movement range is provided with threads to match with the threaded holes 23.

Referring to fig. 6, in another embodiment, the bottom plate 1 is provided with a positioning hole 28, the positioning hole 28 is located right below the screw rod 12, and the diameter of the positioning hole 28 is larger than that of the screw rod 12, so that the lower end of the screw rod 12 can enter the positioning hole 28. After the holding part 15 is removed, the lower end of the screw rod 12 is positioned in the positioning hole 28, at the moment, the screw rod 28 can be used as a steel pipe for steel pipe dance training, so that the flexibility and strength training of other parts of the body can be carried out, and a trainer can carry out multidirectional training only through the device.

Referring to fig. 7, in another embodiment, the second fixing frame 5 is a semi-cylindrical structure, the arc surface of the second fixing frame is disposed upward, and the arc surface is connected with a third flexible layer 29, the third flexible layer 29 is made of sponge, so that when a trainer performs leg pressing training, the contact portion of the second fixing frame 5 and the leg is more comfortable.

When the novel leg fixing frame is used, a trainer holds the holding part 15 by hands, then extends two legs into the first groove 17, presses the control button 16 to enable the elevator 3 to move downwards, and when the elevator 3 moves to just contact the ankle or the leg of the trainer, the elevator stops moving, so that the leg of the trainer is positioned in the first fixing frame 4 and the second fixing frame 5, and meanwhile, certain freedom degree is achieved. Then press the control button 16 that driving motor 13 corresponds, driving motor 13 carries out positive and negative rotation operation according to predetermined periodicity, thereby drive lead screw 12 and carry out regular up-and-down reciprocating motion, this thereby train trainer's waist flexibility, the benefit of doing so is that trainer can master the degree of training according to setting up control button 16 on the portion 15 of gripping at any time, do not need other people supplementary, even break away from the portion 15 because unexpected hand, also can not cause the injury to trainer, because when the hand breaks away from the portion 15 of gripping, lead screw 12's motion has just lost the constraint effect to trainer, make trainer in time break away from possible danger. When only leg training is needed, the leg can be only put on the second fixing frame 5 to perform leg pressing training, so that the flexibility of the leg can be trained.

Finally, it should be understood that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
