[0015] Compared with the prior art, the beneficial effects of the present invention:

[0016] 1. The push-type limiting device for facilitating connection with the limb. The patient sits on the upper surface of the seat, places the patient's legs on the upper surfaces of the calf plate and the thigh plate, and uses straps to fix the patient's legs. The patient's feet rest on the surface of the pedal, achieving the positioning of the patient's legs. At the same time, when the patient's legs perform stretching exercises, the provided bearing two can bend along with the patient's legs, and the provided calf plate and thigh plate are bent and adjusted synchronously.

[0017] 2. The push-type limiting device for facilitating connection with the limb. After the patient sits on the surface of the seat, the patient rotates the rotating handle. Under the meshing action of the ratchet teeth, the transmission chain drives the lifting roller to perform lifting and lowering movements, lowering the lifting roller to a position where the patient's hand can grasp it, enabling the adjustment of the patient's hand, and also being able to adjust the height of the lifting roller to cope with the arm lengths of different patients and perform limb pushing movements for patients of different heights.

[0018] 3. The push-type limiting device for facilitating connection with the limb. After lowering the lifting roller to the position of the patient's hand, the patient rotates the grip by a certain angle so that the limiting block corresponds to the limiting groove position, and the grip can be pulled out a certain length from the central position on the surface of the lifting roller. At the same time, the adjusting rod can be rotated synchronously by an angle, making the two sides on the surface of the adjusting rod correspond to and be clamped with the internal teeth on both sides of the transmission chain, playing a role in fixing the lifting roller.

[0019] 4. The push-type limiting device for facilitating connection with the limb. After the grip is pulled out a certain length from the central position on the surface of the lifting roller, the grip slides to one side through the chute, corresponds to the positioning groove position, and is clamped with the snap ring. Under the action of the thrust, the sleeve rod and the connecting rod drive the slider to slide on the guide rail surface, and then synchronously slide and adjust the patient's legs clamped on the surfaces of the calf plate and the thigh plate. The provided buffer spring can play a buffering effect for the stretching movement of the patient's legs. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0031] 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 present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment

[0033] Please refer to Figure 1 - Figure 7As shown in the figure, the purpose of this embodiment is to provide a push-type limiting device for facilitating limb connection, including a limiting device 100, a lifting mechanism 200, and a pushing mechanism 300. The lifting mechanism 200 is movably installed on one side of the surface of the limiting device 100, and the pushing mechanism 300 is slidably installed on one side of the surface of the lifting mechanism 200. The lifting mechanism 200 includes a lifting unit and a clamping unit. A lifting roller 204 is installed on the surface of the lifting unit, and a grip 205 and an adjusting rod 209 are installed on the surface of the clamping unit. The adjusting rod 209 is movably clamped to both sides of the surface of the limiting device 100 by rotating the grip 205. The pushing mechanism 300 includes a pushing unit and a folding unit. A pedal 304 is installed on the surface of the pushing unit, and a calf plate 312 and a thigh plate 313 are installed on the surface of the folding unit. The calf plate 312 and the thigh plate 313 perform a folding movement on one side of the surface of the lifting mechanism 200 through the pedal 304;

[0034] After the patient sits at the bottom left side of the surface of the limiting device 100 and aligns the patient's legs with the calf plate 312 and the thigh plate 313, the patient's instep is supported by the pedal 304, and the height of the lifting roller 204 is adjusted by using the lifting unit, so that the patient can grasp the grip 205, slide the grip 205 off the surface of the lifting roller 204, and be clamped corresponding to the pushing unit. Then, the calf plate 312 and the thigh plate 313 can be slid left and right on the right side of the surface of the pushing mechanism 300 to perform a push-type stretching movement on the patient's legs. At the same time, the folding unit provided can make the calf plate 312 and the thigh plate 313 bend synchronously with the patient's legs, ensuring that the patient maintains a certain sense of comfort when performing the push-type stretching movement of the legs.

[0035] According to Figure 1 As shown in the figure, considering the need to realize the protection function of the limiting device 100, in this embodiment, the limiting device 100 includes a support frame 101. A back plate 102 is installed on the back of the upper surface of the support frame 101, and a seat 103 is installed on the lower surface of the back plate 102. The two sides of the upper surface of the seat 103 are vertically corresponding to the position of the surface of the lifting mechanism 200;

[0036] Furthermore, through the seat 103 and the back plate 102, the patient can sit and lean against the right side of the surface of the limiting device 100, and the support frame 101 plays a role in supporting and stabilizing the limiting device 100;

[0037] The improvement lies in: effectively enabling the patient to perform a push-type stretching movement on the legs in a sitting position, so that the patient's upper body can be in a relaxed state. At the same time, it does not require the full-time accompaniment of medical staff, reducing the workload of medical staff and also reducing the pressure generated by the patient during limb rehabilitation training.

[0038] According to Figure 2As shown in the figure, considering the need to achieve the clamping function of the lifting unit, in this embodiment, the lifting unit includes a transmission chain 201, a rotating gear 202 is engaged with the lower surface of the transmission chain 201, a rotating handle 203 is connected to the center position of the surface of the rotating gear 202, a lifting roller 204 is engaged with the surface of the transmission chain 201 for lifting, and a grip 205 is rotatably clamped to the center position of the surface of the lifting roller 204;

[0039] Further, by the patient rotating the rotating handle 203, the rotating gear 202 is driven to rotate. Under the action of the meshing of the teeth, the transmission chain 201 is operated, and then the lifting roller 204 is adjusted for lifting on the surface of the transmission chain 201, effectively adjusting the lifting roller 204 to the position of the patient's hand, facilitating the patient to grasp the grip 205;

[0040] The improvement lies in that: after the patient sits on the seat 103, the height of the lifting roller 204 can be directly adjusted, and the grip 205 is adjusted to a position where the patient's hand can grasp it and corresponds to the surface position of the clamping unit, facilitating the subsequent pushing and stretching movement of the patient's legs, and the operation is convenient and simple.

[0041] According to Figure 3 As shown in the figure, considering the need to achieve the clamping function of the clamping unit, in this embodiment, the clamping unit includes a chute 206, a limiting block 207 is fixedly sleeved on the back surface of the grip 205, a limiting groove 208 is formed on the surface of the lifting roller 204, an adjusting rod 209 is connected to the back surface of the grip 205, the chute 206 is formed on one side of the surface of the lifting roller 204, the surface of the chute 206 corresponds to the surface position of the limiting groove 208, and the limiting block 207 is clamped corresponding to the limiting groove 208 by rotating the grip 205;

[0042] Further, after the patient makes the grip 205 correspond to the surface position of the pushing mechanism 300 in parallel, first rotate the grip 205 to make the limiting block 207 correspond to the limiting groove 208, the grip 205 can be pulled out to a certain depth and corresponds to the formed chute 206, so that the grip 205 can slide and separate on the surface of the lifting roller 204 through the chute 206. At the same time, after the grip 205 rotates, the provided adjusting rod 209 rotates synchronously and is clamped corresponding to both sides of the inner wall of the transmission chain 201, playing a role of limiting and clamping the lifting roller 204;

[0043] The improvement lies in that: when the patient rotates the grip 205, under the action of the limiting block 207 and the adjusting rod 209, the grip 205 is separated from the surface of the lifting roller 204 and is clamped corresponding to the surface of the pushing mechanism 300, enabling the patient to perform a pushing and stretching movement on the legs. At the same time, the lifting roller 204 is also limited and clamped on the surface of the transmission chain 201, facilitating the subsequent re-clamping of the grip 205 back to the surface of the lifting roller 204.

[0044] According to Figures 4 - 5 and Figure 7 As shown, considering the need to achieve the pushing function of the pushing unit, in this embodiment, the pushing unit includes a guide rail 301. A slider 302 is slidably connected to the surface of the guide rail 301. A first bearing 303 is movably installed on one side of the surface of the slider 302. A pedal 304 is movably connected to one side of the surface of the first bearing 303. A buffer spring 305 is connected to one side of the surface of the pedal 304. A through groove 306 is formed on the upper surface of the guide rail 301. A connecting rod 307 is connected to the upper surface of the slider 302. A sleeve rod 308 is fixedly sleeved on one side of the upper surface of the connecting rod 307. A clamping ring 310 is fixedly connected to one side of the surface of the sleeve rod 308. A positioning ring 309 is sleeved on one side of the surface of the sleeve rod 308. A positioning groove 311 is formed around the outer surface of the clamping ring 310. The surface of the clamping ring 310 is movably clamped with the surface of the handle 205;

[0045] Furthermore, by correspondingly clamping the handle 205 with the clamping ring 310, the sleeve rod 308 and the connecting rod 307 are synchronously pushed on the surface of the positioning ring 309, and the slider 302 is used to slide left and right on the surface of the guide rail 301. The pedal 304 can support the patient's foot, and at the same time, the first bearing 303 provided can enable the pedal 304 to rotate and adjust on the surface of the slider 302;

[0046] The improvement lies in that the clamping ring 310 and the positioning ring 309 can enable the handle 205 to always slide left and right in a straight line state. At the same time, the first bearing 303 provided can facilitate the patient to adjust the angle of the foot, effectively enabling the patient's foot to step on the surface of the pedal 304 stably and comfortably, and the buffer spring 305 provided has a certain buffering effect on the leg pushing and stretching movement of the patient.

[0047] According to Figure 6 As shown, considering the need to achieve the folding function of the folding unit, in this embodiment, the folding unit includes a calf plate 312. A second bearing 314 is connected to one side of the surface of the calf plate 312. A thigh plate 313 is connected to one side of the surface of the second bearing 314. A strap 315 is connected to the outer surface of the second bearing 314. One side of the surface of the calf plate 312 is fixedly connected to the lower surface of the pedal 304. The calf plate 312, the thigh plate 313 and the pedal 304 are synchronously slid left and right on the surface of the guide rail 301 through the slider 302;

[0048] Furthermore, by placing the patient's leg on the upper surfaces of the calf plate 312 and the thigh plate 313 and using the strap 315 to fix the leg joint position, when the patient's leg is subjected to a pushing and stretching movement, the second bearing 314 provided can enable the calf plate 312 and the thigh plate 313 to bend and keep the same movement as the patient's leg;

[0049] The improvement lies in: using the second bearing 314 to let the patient perform a leg pushing stretching exercise. During this process, the lower leg plate 312 and the thigh plate 313 can produce a synchronous adaptation effect with the patient's leg, effectively enabling the patient to maintain a certain sense of comfort when performing the leg pushing stretching exercise.

[0050] To sum up, the working principle of this solution is as follows: The patient sits on the upper surface of the seat 103, places the patient's leg on the upper surfaces of the lower leg plate 312 and the thigh plate 313, uses the strap 315 to fix the patient's leg, and the patient's foot presses against the surface of the pedal 304 to position the patient's leg. At the same time, when the patient's leg performs a stretching exercise, the second bearing 314 provided can bend along with the patient's leg, and the provided lower leg plate 312 and thigh plate 313 bend and adjust synchronously, and the pedal 304 also tilts and adjusts along with the first bearing 303 on the surface of the slider 302 to ensure the stretching exercise of the patient's leg and maintain a sense of comfort.

[0051] After the patient sits on the surface of the seat 103, the patient rotates the rotating handle 203. Under the meshing action of the ratchet teeth, the transmission chain 201 drives the lifting roller 204 to perform a lifting movement, lowers the lifting roller 204 to a position where the patient's hand can grasp it, can adjust the patient's hand, and can also adjust the height of the lifting roller 204 according to the arm lengths of different patients to perform limb pushing movements for patients of different heights.

[0052] After lowering the lifting roller 204 to the patient's hand position, the patient rotates the grip 205 by a certain angle so that the position of the limit block 207 corresponds to the position of the limit groove 208. The grip 205 can be pulled out a certain length from the central position on the surface of the lifting roller 204. At the same time, the adjusting rod 209 can be rotated synchronously by an angle so that both sides of the surface of the adjusting rod 209 are correspondingly clamped with the racks on both inner walls of the transmission chain 201 to fix the lifting roller 204. After the grip 205 is pulled out a certain length from the central position on the surface of the lifting roller 204, the grip 205 slides to one side through the chute 206, corresponds to the position of the positioning groove 311, and is correspondingly clamped with the snap ring 310. Under the action of the thrust, the sleeve rod 308 and the connecting rod 307 drive the slider 302 to slide on the surface of the guide rail 301, and then synchronously slide and adjust the patient's leg clamped on the surfaces of the lower leg plate 312 and the thigh plate 313. The provided buffer spring 305 can play a buffering effect to perform a limb stretching exercise on the patient's leg.
