Description

Technical Field

[0001] The present invention relates to the technical field of training devices, and particularly to a dance rehabilitation training device. Background Art

[0002] Rehabilitation training is an important means in rehabilitation medicine. It mainly enables the patient's affected limb to recover normal self-care functions through training, and enables the physical and psychological rehabilitation of the disabled as much as possible through training;

[0003] In dance training, due to intensity problems, there are often some injuries and illnesses, such as Achilles tendon tears. Injuries to the Achilles tendon require dancers to go through stages such as surgery, recuperation, and rehabilitation;

[0004] The existing structures for Achilles tendon recovery training ignore that patients cannot exert force due to long-term Achilles tendon injuries, so the strength of the calf muscles and the Achilles tendon needs to be strengthened. Only after the Achilles tendon is strengthened can the patient walk on the ground. Otherwise, the un-recovered initial-strength Achilles tendon cannot bear such intensity when walking. Summary of the Invention

[0005] The purpose of the present invention is to solve the defect in the prior art that after the Achilles tendon is injured and not recovered, subsequent injuries continue to occur, and a dance rehabilitation training device is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical scheme:

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0030] Embodiment 1

[0031] In view of the fact that the traditional Achilles tendon rehabilitation structure uses the pulling method to strengthen the training of muscle groups, but the pulling method will cause the muscles of the calf and thigh to compensate, so that the muscle groups near the Achilles tendon cannot be fully trained;

[0032] Refer to Figure 1-3 , a dance rehabilitation training device, including a base 1 and a pedal 2 arranged on the base 1;

[0033] A placement groove 12 is opened in the upper part of the base 1, a through-type square through-hole 3 is opened at the bottom of the pedal 2, and multiple rubber sleeves 4 are arranged on the upper part of the pedal 2;

[0034] A rope 5 is fixedly installed on the back of the pedal 2, and a counterweight assembly is connected to the lower end of the rope 5 for weight adjustment. A connecting frame 7 is parallelly installed on one side of the base 1, and a through-type guiding hole 6 is vertically opened at the distal end of the connecting frame 7, and the rope 5 passes through the guiding hole 6 and extends below the connecting frame 7;

[0035] In this device, the heel position of the patient is placed on the ankle fixing bracket 13, and the upper sole is sleeved inside the rubber sleeve 4. Since the sole has a physiological curve, a square through-hole 3 is opened at the lower end of the pedal 2, so that the lower sole is located inside the direction through-hole 3, and the upper sole is closely attached to the upper part of the pedal 2. The counterweight plate 10 is placed on the disc 9 for weight adjustment, so that at different rehabilitation stages, the weight adjustment can maximally meet the training of the muscles for weight.

[0036] The upper sole fits closely with the pedal 2 and rotates around the heel as the center. This can maximize the rotation angle of the sole. The larger the rotation angle, the more the muscle groups near the Achilles tendon can be maximally stimulated. And during this process, the muscles of the leg are avoided from participating, reducing the compensation of the leg muscles. The more effective the rehabilitation training for the Achilles tendon is;

[0037] The downward and upward pressing of the pedal 2 can stimulate the relaxation and stretching of the Achilles tendon part, and the Achilles tendon is trained using this principle;

[0038] Secondly, the connecting frame 7 and the guiding hole 6 can move the rope 5 away from the position of the base 1. In this way, during the up and down movement of the rope 5, there will be no contact friction with the pedal 2 and the base 1. Because vibration will occur during contact friction, this kind of vibration is unfavorable to the Achilles tendon that is in the process of rehabilitation. Therefore, reducing the vibration during the movement of the rope 5 can protect the Achilles tendon during rehabilitation training;

[0039] Embodiment 2

[0040] Reference Figure 8 , the difference between this embodiment and Embodiment 1 is that the counterweight assembly includes a round rod 8, a disc 9, and a counterweight disc 10. The round rod 8 is connected to the lower end of the rope 5, the counterweight disc 10 is horizontally connected to the bottom of the round rod 8, and the counterweight disc 10 is placed on the upper end of the disc 9,

[0041] The counterweight disc 10 is circularly arranged. A notch 19 is vertically opened on the counterweight disc 10. The notch 19 is clamped on the outside of the round rod 8, and the size of the round rod 8 and the notch 19 are matched with each other. The counterweight disc 10 is placed on the disc 9 to adjust the weight, so that during different rehabilitation stages, the weight adjustment can maximally meet the muscle's training requirements for weight.

[0042] Embodiment 3

[0043] During the rehabilitation training process, the sole rotates around the position of the heel, and the position of the heel presents an irregular movement mode. In this way, the direction of the force received by the Achilles tendon is irregular, which causes too much stimulation to the Achilles tendon and instead leads to problems with the Achilles tendon;

[0044] Reference Figure 1-7 , the difference between this embodiment and Embodiment 1 is that a chamber 17 is opened on the base 1 below the square through hole 3, a traction structure is also arranged inside the chamber 17, and the chamber 17 is communicated with the placement groove 12;

[0045] The traction structure includes an ankle fixing frame 13, a tray 14, a guide rod 15, a reset spring 16 and a connection hole 18. The connection holes 18 are distributed in an array on the tray 14. The guide rod 15 is installed on one side of the chamber 17, and the guide rod 15 passes through the connection hole 18 and extends to the other side of the tray 14. The outer side of the guide rod 15 is sleeved with a reset spring 16. The two ends of the reset spring 16 are respectively fixed on one side of the chamber 17 and the tray 14. The ankle fixing frame 13 is installed on the upper part of the tray 14, and the tray 14 is slidably arranged on the inner side of the chamber 17, and the size of the chamber 17 matches the size of the tray 14.

[0046] The ankle fixing frame 13 is arranged in an arc shape, and the pedal 2 is arranged on the upper end of the base 1 in an inverted form through the hinge 11;

[0047] First, the calf of the person being rehabilitated is placed on the inner side of the placement groove 12, and the heel is placed on the inner side of the ankle fixing frame 13. The tray 14 at the bottom of the ankle fixing frame 13 can move in a linear trajectory inside the chamber 17. When the upper sole drives the pedal 2 to be lifted, the heel drives the ankle fixing frame 13 to move to the side away from the placement groove 12. When the upper sole drives the pedal 2 to be pressed down, the heel drives the ankle fixing frame 13 to move to the side close to the placement groove 12. This arrangement can effectively limit the movement trajectory of the heel. At the same time, a return spring 16 is arranged between the tray 14 and the chamber 17. The return spring 16 is sleeved on the outside of the guide rod 15. The guide rod 15 plays a guiding role, and the return spring 16 can bring resistance to the heel during movement, as well as the effect of the tray 14 being reset. Regarding the resistance brought by the return spring 16, the upper sole and the heel position can be affected during training, so that the force on the entire sole is balanced, preventing the upper sole from being stressed while the heel is suspended, which further leads to the involvement and compensation of the calf muscles.

[0048] The working principle of the device is:

[0049] The device places the patient's heel on the ankle fixing frame 13, and the upper sole is set on the inner side of the rubber sleeve 4. Since the sole has a physiological curve, a square through hole 3 is opened at the lower end of the pedal 2, so that the lower sole is located on the inner side of the direction through hole 3, and the upper sole is close to the upper part of the pedal 2. The weight plate 10 is placed on the disc 9 to adjust the weight, so that in different rehabilitation stages, the weight adjustment can meet the muscle weight training to the greatest extent;

[0050] The upper sole of the foot fits with the pedal 2 and rotates with the heel as the center of the circle, which can maximize the rotation angle of the sole of the foot. The larger the rotation angle, the more the muscle groups near the Achilles tendon can be stimulated. In this process, the leg muscles are avoided from being involved, and the leg muscle compensation is reduced, so the rehabilitation training of the Achilles tendon is more effective.

[0051] When the pedal 2 is depressed and lifted, it can stimulate the relaxation and stretching of the Achilles tendon area, and the Achilles tendon is trained based on this principle;

[0052] Secondly, the connecting frame 7 and the guiding hole 6 can move the rope 5 away from the base 1. In this way, during the up and down movement of the rope 5, there will be no contact friction with the pedal 2 and the base 1. Because vibration will be generated during contact friction, such vibration is not beneficial to the Achilles tendon in the process of rehabilitation. Therefore, reducing the vibration during the movement of the rope 5 can protect the Achilles tendon during rehabilitation training;

[0053] First, place the calf of the rehabilitee inside the placement groove 12 and the heel inside the ankle fixing frame 13. The tray 14 at the bottom of the ankle fixing frame 13 can move in a linear trajectory inside the chamber 17. When the upper sole drives the pedal 2 to lift, the heel drives the ankle fixing frame 13 to move away from the placement groove 12. When the upper sole drives the pedal 2 to depress, the heel drives the ankle fixing frame 13 to move closer to the placement groove 12. Such a setting method can effectively limit the movement trajectory of the heel. At the same time, a return spring 16 is provided between the tray 14 and the chamber 17. The return spring 16 is sleeved outside the guiding rod 15. The guiding rod 15 plays a guiding role, and the return spring 16 can bring resistance to the heel during movement and the effect of resetting the tray 14. Regarding the resistance brought by the return spring 16, during training, both the upper sole and the heel positions can be subjected to force, so that the entire sole is in force balance, preventing the upper sole from being stressed while the heel is suspended, which may further lead to the participation and compensation of the calf muscles.

[0054] As described above, only the preferred specific implementation manner of the present invention is provided, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
