Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0040] Embodiment 1:

[0041] Reference Figure 1-Figure 3 The utility model provides an embodiment: a hip joint autonomous function training auxiliary device, including a rear strap 1, the rear strap 1 and the front strap 205 can be tied to the patient's calf to fix the device, the outer wall of the rear strap 1 is provided with two groups of telescopic mechanisms 4, after the telescopic mechanism 4 is extended, the lever principle can be used to facilitate internal and external rotation force, a group of telescopic mechanisms 4 The front end outer wall is provided with a winding mechanism 2, and the front strap 205 can be automatically wound up by the winding mechanism 2 to facilitate the patient to wear the device, and can adapt to patients with different calf thicknesses.

[0042] Reference Figure 2-Figure 3 The winding mechanism 2 includes a winding drum 201, which is fixed to the front end outer wall of a group of support rods 401 on the right side. The inner wall of the winding drum 201 is fixedly connected with a partition 204. Two groups of partitions 204 are provided and are symmetrically distributed in the upper and lower inner walls of the winding drum 201. A limiting component is provided on the top outer wall of the winding drum 201. The inner wall of the winding drum 201 is clamped with a rotating shaft 202 through the limiting component. The limiting component can limit the rotating shaft 202 to fix the length of the front strap 205 pulled out. The rotating shaft 202 is rotatably connected to the inner wall of the winding drum 201. When the front strap 205 is pulled outward, the rotating shaft 202 can rotate accordingly.

[0043] Reference Figure 2-Figure 3The outer wall of the rotating shaft 202 is fixedly connected with a spiral spring 203. The spiral spring 203 is also provided with two groups and is symmetrically distributed in the upper and lower inner walls of the winding drum 201. One end of the spiral spring 203 is fixedly connected to the outer wall of the rotating shaft 202, and the other end of the spiral spring 203 is fixedly connected to the inner wall of the winding drum 201. When the front strap 205 is pulled outward, the rotating shaft 202 rotates and drives the spiral spring 203 to contract under force. When the front strap 205 stops being pulled, the rotating shaft 202 is reversed due to the elastic force of the spiral spring 203 itself. By rotating in the direction, the front strap 205 can be automatically rolled up into the winding drum 201, so that the front strap 205 and the rear strap 1 are fixed to the calf. The inner wall of the top end of the rotating shaft 202 is provided with multiple groups of grooves 206, and the grooves 206 can be engaged with the clamping block 304 to limit the rotating shaft 202 and fix the length of the front strap 205 pulled out. The outer wall of the rotating shaft 202 is wrapped with the front strap 205, and the device can be fixed by the front strap 205 and the rear strap 1, and the front strap 205 can be automatically rolled up and fixed after the patient puts it on, which is more convenient.

[0044] Reference Figure 3 The limiting assembly includes a fixed block 301, which is fixedly connected to the top outer wall of the winding drum 201. The inner wall of the fixed block 301 is elastically connected to a pull rod 303 through a spring A302. Pulling the pull rod 303 upwards can release the limit of the rotating shaft 202. The pull rod 303 passes through the top outer wall of the winding drum 201. When not affected by external force, the pull rod 303 pops up downward due to the elastic force of the spring A302 itself, and the bottom end of the pull rod 303 is plugged into the top inner wall of the rotating shaft 202.

[0045] Reference Figure 3 One end of the spring A302 is fixedly connected to the outer wall of the pull rod 303, and the other end of the spring A302 is fixedly connected to the inner wall of the fixed block 301. The outer wall of the pull rod 303 is slidably connected to the inner wall of the fixed block 301. When the pull rod 303 is pulled upward, the block 304 is disengaged from the groove 206, and the front strap 205 can be pulled outward, so that the patient can put his legs into the front strap 205 and the rear strap 1, and the block 304 is engaged with the groove 206. The arrangement of the group of grooves 206 enables the block 304 to engage with the grooves 206 when the rotating shaft 202 is rotated to multiple angles, so that the front strap 205 can be pulled out to different lengths and fixed to accommodate patients with different calf thicknesses. The outer wall of the bottom end of the pull rod 303 is fixedly connected with the block 304, and the block 304 is engaged with the grooves 206. At this time, the rotating shaft 202 can be limited, and the length of the front strap 205 pulled out can be fixed, and the device can be fixed to the patient's calf.

[0046] Reference Figure 4-Figure 5The telescopic mechanism 4 includes a support rod 401, which is fixedly connected to the outer wall of the rear strap 1. The telescopic mechanism 4 is provided with two groups. The two groups of support rods 401 are respectively fixed to the outer walls of both ends of the rear strap 1. The outer wall of the support rod 401 is fixedly connected to the outer wall of the winding drum 201. The winding drum 201 is fixed to the front end outer wall of the right group of support rods 401. One end of the front strap 205 is fixedly connected to the outer wall of the rotating shaft 202, and the other end is fixedly connected to the outer wall of the left group of support rods 401.

[0047] Reference Figure 4-Figure 5 The outer wall of the support rod 401 is fixedly connected to the outer wall of the front strap 205, and the inner wall of the support rod 401 is slidably connected to the moving rod 402. The overall length of the telescopic mechanism 4 can be adjusted by pulling the moving rod 402. The outer wall of the support rod 401 is fixedly connected to the protrusion 405, and the inner wall of the protrusion 405 is elastically connected to the limiting rod 404 through the spring B406. When not affected by external force, the limiting rod 404 pops out outward due to the elastic force of the spring B406 itself and engages with the slot 403, thereby fixing the position of the moving rod 402.

[0048] Reference Figure 4-Figure 5 One end of the spring B406 is fixedly connected to the outer wall of the limit rod 404, and the other end of the spring B406 is fixedly connected to the inner wall of the protrusion 405. The outer wall of the limit rod 404 is slidably connected to the inner wall of the protrusion 405. When it is necessary to pull the moving rod 402, the limit rod 404 can be pulled outward to make the limit rod 404 disengage from the slot 403, so that the limit of the moving rod 402 can be released, and the moving rod 402 can be pulled out. By utilizing the principle of leverage, the length of the force arm is increased to drive the hip joint to flex, such as the hip joint in the sitting or supine hip flexion position, to exert force internally and externally, so as to exercise. The outer wall of the moving rod 402 is provided with multiple groups of slots 403, and the limit rod 404 is engaged with the slots 403. The setting of multiple groups of slots 403 can enable the moving rod 402 to be pulled out to multiple lengths for fixation, which is convenient for different patients to use.

[0049] Embodiment 2:

[0050] Reference Figure 6-Figure 8The top inner wall of the moving rod 402 is provided with a rotating mechanism 5, and the folding handle 503 can be rotated laterally through the rotating mechanism 5, and can be directed toward both sides or toward the patient himself, so as to be adjusted according to the patient's comfort level of exertion. The rotating mechanism 5 includes a rotating rod 501, and the rotating rod 501 is rotatably connected to the top inner wall of the moving rod 402. The folding handle 503 can be rotated by rotating the rotating rod 501, and the top outer wall of the rotating rod 501 is rotatably connected to the folding handle 503. The folding handle 503 can be stored in the rotating rod 501 when not in use to reduce space. When it is needed, the folding handle 503 can be unfolded, and the folding handle 503 can be held with both hands when the patient is in a supine position. 03 Traction assists in flexion and extension of the hip joint, increases the degree and strength of hip joint flexion, the outer wall of the moving rod 402 is threadedly connected with a positioning bolt 502, and the positioning bolt 502 contacts the outer wall of the rotating rod 501. When the rotating rod 501 needs to be rotated to adjust the direction of the folding handle 503, the positioning bolt 502 can be loosened to disengage it from the rotating rod 501, and the rotating rod 501 can be rotated to rotate the folding handle 503. When the folding handle 503 is rotated to a suitable position, the positioning bolt 502 can be tightened to make the positioning bolt 502 fit tightly with the rotating rod 501, so that the rotating rod 501 can be limited and the direction of the folding handle 503 can be fixed.

[0051] Working principle: When in use, the patient can first pull the pull rod 303 upward to disengage the block 304 from the groove 206, and then pull the left set of support rods 401 outward to drive the front strap 205 to be pulled outward, and the front strap 205 drives the rotating shaft 202 to rotate, so that the scroll spring 203 is forced to contract. After the front strap 205 is fully pulled open, the patient can pass the calf through the front strap 205 and the rear strap 1, so that the top of the front strap 205 and the rear strap 1 is flush with the patient's knee joint, and then the right set of support rods 401 can be loosened, and the scroll spring 203 can be pulled outward. The spring 203 drives the shaft 202 to rotate in the opposite direction due to its own elastic force, so that the front strap 205 is wound around the shaft 202, and the winding is automatically completed. At this time, the pull rod 303 can be loosened, so that the pull rod 303 pops up downward due to the elastic force of the spring A302 itself, and the block 304 is engaged with the groove 206, so that the position of the shaft 202 can be fixed, thereby fixing the length of the front strap 205 pulled out, and automatically fitting the front strap 205 to the patient's calf, and combining with the rear strap 1 to fix the device on the patient's calf, it can be worn and used.

[0052] Then the patient can flip the folding handle 503 outward, and then pull the limit rod 404 outward to disengage the limit rod 404 from the slot 403, pull the moving rod 402 upward to a certain length, and then engage the limit rod 404 with the slot 403 to fix the length between the moving rods 402 and the moving rods 402. After the support rod 401 and the moving rod 402 are extended, the lever principle can be used to make it easier to exert force for internal and external rotation. At this time, the telescopic mechanism 4 can be pushed left and right, and the lever principle can be used to increase the length of the force arm, so as to drive the hip flexion position such as sitting or supine hip flexion position to exert force, and perform functional exercises for internal and external rotation of the hip joint. The patient can cross the calf on the knee of the other leg, and by pushing the telescopic mechanism 4 up and down, it is more convenient to exert force for cross-legged exercise using the lever principle.

[0053] When performing hip flexion exercises, the patient does not need to pull out the moving rod 402, but can directly unfold the folding handle 503 and loosen the positioning bolt 502 to adjust the direction of the folding handle 503, such as Figure 8 As shown, when the folding handle 503 is adjusted to a position where the patient can hold it more comfortably and then fixed with the positioning bolt 502, the patient can hold the folding handle 503 with both hands in a supine position and pull it, thereby pulling the calf with the upper limbs to further assist in flexing and extending the hip joint, so that the hip joint can be flexed to the largest possible required angle for exercise, thereby avoiding the problem that the patient has no force point in the hip joint and is unable to exercise alone, thereby achieving hip flexion and internal and external rotation exercises for a single person.

[0054] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
