Description

Technical Field

[0001] The invention relates to the technical field of rehabilitation devices, and in particular to an automatic ankle fastening device. Background Art

[0002] According to records, all tissues and organs of the human body are supported by the skeletal system, especially the spine that supports the center. The spine is composed of seven cervical vertebrae, twelve thoracic vertebrae, five lumbar vertebrae and one sacral vertebra. The central nervous system passes through the gaps between the vertebrae from the spinal cord. Once the vertebrae are displaced or bent, or compression or even strain on the surrounding muscles and ligaments occurs, it will directly affect the passing nerves and indirectly cause the end organs, muscles or secretory glands supplied by the nerves. In addition, as long as the spinal nerves are compressed, it will not only cause pain on the surface of the limbs, but also paralysis of the hands and feet in severe cases, and will also cause the decay of internal organs and other organs.

[0003] Long-term abnormal cervical spine posture will result in the following consequences:

[0004] 1. The trapezius muscles at the back of the neck and shoulders are tense (the trapezius muscles of people with neck and shoulder pain will be stiff);

[0005] 2. Strain causes certain muscles in the front and back of the neck to be passively strengthened or stretched, causing them to contract weakly, which in turn compresses nerves and blood vessels, affecting the normal oxygen and blood supply to the brain; and,

[0006] 3. Frequent bad postures can cause bone deformation and form bad body postures, such as thoracic curvature, scoliosis, hunchback, uneven shoulders, etc. Therefore, spinal rehabilitation is based on neuroanatomy and biomechanics as its theoretical basis, using appropriate techniques to quickly correct the spine, so that the spinal nerves can be relieved and the root cause of the pain can be eliminated. To solve more serious spinal diseases, surgery is the only way, while milder spinal symptoms can be improved through auxiliary medical equipment such as muscle electrical stimulation, waist belts or spinal braces, or sitting or lying physiotherapy beds combined with physiotherapists' massage or other techniques.

[0007] Medical institutions often use stretching equipment or traction equipment to correct or rehabilitate patients. For example, the applicant of this case proposed patent number: ZL200710034811.3 "Three-dimensional vector spine rehabilitation device", and patent announcement number I324511 "Three-dimensional vector spine rehabilitation device". However, for the muscle groups around the neck and shoulders, a more supportive and soothing device is needed to achieve comprehensive symptom relief of cervical and lumbar disc syndrome.

[0008] Another example is patent cases No. 201031393, No. I542306 or No. 201031393, which have structures for fixing the ankles of users, such as Figures 1 to 2CAs shown, the rehabilitation device 1 comprises an upper section 11, a middle section 12, a lower section 13 and an ankle fixing section 14. The user's head is at the upper section 11, the body lies or crouches at the middle section 12, and the buttocks and legs extend from the lower section 13 to the ankle fixing section 14. It should be noted that the structure and technical features of the rehabilitation device 1 are not the subject of this case, and only the ankle fixing section 14 for fixing the user's ankle is briefly described here.

[0009] The ankle fixing section 14 extends from the lower section 13 and has a symmetrical ankle cushion 141. A support rod 142 is provided between the two ankle cushions 141. A connecting rod 143 that can slide up and down and position is sleeved on the support rod 142. An ankle fixing pad 144 is provided on the connecting rod 143. When the user takes a prone position on the rehabilitation device 1, the height of the connecting rod 143 is adjusted so that the bottom of the ankle fixing pad 144 rests on the user's ankle. Although the ankle fixing section 14 can properly support and fix the user's ankle, there are still many deficiencies in actual use, such as: the connecting rod 143 must be manually operated to adjust the height of the ankle fixing pad 144, which is not only time-consuming and labor-intensive, but also may affect the user's comfort and safety. Secondly, the sliding and positioning of the connecting rod 143 may not be accurate and stable enough, resulting in an inappropriate or changed position of the ankle fixing pad 144, affecting the rehabilitation effect. Moreover, such a design requires another person to manually install the ankle fixing section 14 to fasten the ankle, which is very unsuitable for the user to fasten the ankle fixing section 14 by himself. In view of the above shortcomings in practice, the inventor studied methods to improve the above shortcomings and finally produced the present invention. Summary of the invention

[0063] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] like Figure 3 To Figure 5 As shown, it can be seen that the structure of the present invention is connected to the default rehabilitation device 2, which has a head section 21, a body section 22, a lower limb end 23, and a support frame 24, and the support frame 24 is provided with a connecting plate 241; it should be noted that the structure and technical features of the rehabilitation device 2 are not the target of this case, and the head section 21, the body section 22, the lower limb end 23, and the support frame 24 are not repeated here; the ankle frame automatic buckling device 3 at least includes: a plurality of ankle pads 31, an electrically controlled drive motor 33, and a rotating support frame 34, wherein:

[0065] The ankle pads 31 are symmetrically arranged on the connecting plates 241 .

[0066] A plurality of fixing seats 32 are respectively arranged under the connecting plate 241 to fix the electric control driving motor 33 on the connecting plate 241. The electric control driving motor 33 is extended with a rotating shaft 331, and the rotating shaft 331 is between two correspondingly arranged fixing seats 32. The electric control driving motor 33 can be a servo motor, a stepping motor, a pneumatic rotating shaft, a hydraulic rotating shaft, or a traditional motor with a speed controller.

[0067] The rotating support frame 34 includes a shaft connection portion 341, a T-shaped tube 342, and a plurality of rollers 343, wherein: the shaft connection portion 341 is provided at one end of the rotating support frame 34, and the T-shaped tube 342 is provided at the other end, and the shaft connection portion 341 is shaft-connected to the rotating shaft 331; there is a height difference between the rotating support frame 34 and the shaft connection portion 341. In a preferred embodiment, the rotating support frame 34 is connected to the shaft connection portion 341 after being bent in an arc shape, or the rotating support frame 34 is connected to the shaft connection portion 341 after being bent obliquely, so as to achieve a structure in which a height difference is formed between the rotating support frame 34 and the shaft connection portion 341;

[0068] Each flexible roller 343 is provided with an axis set 344 at the axis center. Further explanation is required: the roller 343 is composed of a connecting shaft 3441, two sleeves 3442, and a plurality of connecting components 3443, and is sleeved and assembled with the aforementioned T-tube 342; the axis set 344 is sleeved on the T-tube 342, and the sleeve 3442 of the axis set 344 is provided with a plurality of bearings or linear bearings, so that the flexible roller 343 can reciprocate and rotate and swing on the T-tube 342; the flexible roller 343 can be made of foam, silicone or rubber material.
