[0038] The following will be combined with Figures 1 - 12Describe a leg exercise device for geriatric care of the present invention, including: an exercise seat 100, and a fixed seat 200 fixedly connected to the surface of the exercise seat 100; an exercise mechanism 300, the exercise mechanism 300 is installed on the surface of the fixed seat 200, and the surface of the exercise mechanism 300 extends to the lower end of the exercise seat 100; wherein, the exercise mechanism 300 includes a strength component 310 installed inside the fixed seat 200, an angle component 320 is arranged at one end of the strength component 310 away from the fixed seat 200, a calf placement seat 340 is connected below the angle component 320, and an electric control component 330 is arranged on one side of the angle component 320 and the strength component 310, and the surface of the electric control component 330 extends to one side of the fixed seat 200;

[0039] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 12 As shown, the strength component 310 includes two connecting frames 311, a regulating seat 312 and a connecting seat 314. The two connecting frames 311 are respectively arranged between the fixed seat 200 and the angle component 320. The regulating seat 312 is fixedly connected to one end of the connecting frame 311 close to the fixed seat 200. The regulating seat 312 is hinged to the inner side of the fixed seat 200. The connecting seat 314 is arranged between the two connecting frames 311. A side sliding rod 313 is fixedly connected to one side of the connecting seat 314 close to the electric control component 330. The side sliding rod 313 is slidably connected to one side of the connecting frame 311. A side groove 3115 is opened on one side of the connecting frame 311 close to the electric control component 330. A middle hole 3111 is opened inside the connecting frame 311. Guide holes 3112 are opened on the side surface of the connecting frame 311 above and below the middle hole 3111. A positioning groove 3113 is opened on the surface of the connecting frame 311 close to the guide hole 3112. A positioning rod 3114 is slidably connected to the inner wall of the positioning groove 3113. The side sliding rod 313 is slidably connected to the inner wall of the side groove 3115;

[0040] A middle rod 315 is fixedly connected to the inner wall of the connecting seat 314. Pistons 3151 are fixedly connected to both ends of the middle rod 315. The pistons 3151 are slidably connected to the inner wall of the adjacent middle hole 3111. Guide rods 3152 are arranged above and below the middle rod 315 and are embedded and installed inside the connecting seat 314. The guide rods 3152 are slidably connected to the inner wall of the adjacent guide hole 3112;

[0041] When the device is in use, the electric control component 330 can drive two side sliding rods 313 to slide inside the side grooves 3115. The positioning rod 3114 slides inside the positioning groove 3113, and the positioning rod 3114 is positioned inside the positioning groove 3113 by cooperating with bolts, so as to be appropriately adjusted according to the leg length of the patient. When moving, under the action of the positioning rod 3114, the two connecting frames 311 are positioned, and in cooperation with the side sliding rod 313 sliding inside the side groove 3115, the stability of the sliding of the connecting seat 314 can be maintained. At the same time, the middle rod 315 drives the piston 3151 to slide inside the middle hole 3111. At this time, under the action of the piston 3151, the gas inside the middle hole 3111 is extruded. Through extrusion, the gas inside the connecting frame 311 is discharged to the outside relatively slowly. Thus, when the elderly are undergoing rehabilitation exercises, relatively slow movements can be formed, avoiding excessive exercise intensity of the patient and damaging muscle tissues, and protecting the safety of the patient's nursing and rehabilitation;

[0042] The regulation seat 312 includes a hinge frame 3121, a circular seat 3122 and a rubber seal 3123. The hinge frame 3121 is hinged to the inner side of the fixed seat 200. The circular seat 3122 is fixedly connected to the inside of the hinge frame 3121. The rubber seal 3123 is fixedly connected to the inner wall of the hinge frame 3121. A regulation knob 3124 is rotatably connected to the surface of the circular seat 3122. One side of the regulation knob 3124 is fixedly connected to a communication pipe 3125. The other end of the communication pipe 3125 extends into the adjacent middle hole 3111. An O-ring 3126 is embedded on the surface of the communication pipe 3125. The O-ring 3126 contacts the inner wall of the adjacent middle hole 3111. A plurality of groups of ventilation holes 3127 are formed on the surface of the communication pipe 3125;

[0043] When the device is in use, the movement of the middle rod 315 drives the piston 3151 to extrude the gas inside the middle hole 3111. The gas is extruded and enters the inside of the communication pipe 3125, and is discharged to the outside through the ventilation holes 3127. There are four groups of ventilation holes 3127 in total, and the number of air outlet holes in each group of ventilation holes 3127 is different, so that the gas discharge amount is different. The rubber seal 3123 can block three groups of ventilation holes 3127. When the patient needs to make adjustments, the regulation knob 3124 can be manually rotated to adjust the air output of different ventilation holes 3127, and thus different adjustments can be made to the exercise effect of the patient;

[0044] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10As shown, the angle component 320 includes a connecting angle bracket 321, a connecting angle seat 322, and a sector gear ring 3221. The connecting angle bracket 321 is fixedly connected to the end of another connecting bracket 311 away from the fixed seat 200. The connecting angle seat 322 is rotatably connected to the inner wall of the connecting angle bracket 321. The sector gear ring 3221 is fixedly connected to the upper end of the connecting angle seat 322. The lower end of the connecting angle seat 322 is fixedly connected to the upper end of the lower leg placement seat 340. A sector gear 323 is arranged inside the connecting angle bracket 321. A directional block 3241 is fixedly connected to the inner wall of the sector gear 323. An outer arc groove 3212 is formed on the side of the connecting angle bracket 321, and an inner arc groove 3211 is formed inside the connecting angle bracket 321. An edge arc stopper 3213 is fixedly connected to the inner wall of the outer arc groove 3212 near the connecting cross bar 324. An arc-shaped sliding block 3215 is slidably connected to the inner wall of the outer arc groove 3212. A through hole 3214 is formed on one side of the arc-shaped sliding block 3215. A limiting screw 3216 is threadedly connected to the inner walls of two of the through holes 3214. A connecting cross bar 324 is fixedly connected to the inner wall of the directional block 3241. One end of the connecting cross bar 324 penetrates to the outside of the connecting angle bracket 321 and is fixedly connected to a connecting round block 3242;

[0045] When in use, the patient places the lower leg on the lower leg placement seat 340. During leg exercise, the lower leg placement seat 340 is driven to swing by the leg, thereby driving the connecting angle seat 322 to follow and offset in angle. At this time, the sector gear ring 3221 rotates and limits the angle of the inner arc groove of the sector gear 323 through the two arc-shaped sliding blocks 3215 and under the action of the limiting screw 3216. Through such a limit, the amplitude of the patient's leg exercise can be controlled, avoiding a large angle during the patient's leg exercise and straining the patient's leg muscle tissue, and assisting in ensuring the safety of the patient's exercise operation;

[0046] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 、 Figure 11 、 Figure 12As shown in the figure, the electric control component 330 includes a receiver group 331, a first articulated rod 332 and a second articulated rod 333. The receiver group 331 is installed on the side surface of the connecting angle bracket 321. The first articulated rod 332 is installed on the surface of the connecting cross bar 324. A transmitter 3321 is embedded inside the first articulated rod 332. The second articulated rod 333 is articulated at the lower end of the first articulated rod 332. The other end of the second articulated rod 333 is articulated with a horizontal push rod 334. The other end of the horizontal push rod 334 is fixedly connected to a connecting plate 335. The other side of the connecting plate 335 is connected with an electric push rod 336. The electric push rod 336 is fixedly connected to the side surface of the adjacent connecting frame 311. The electric control component 330 further includes a controller 337 installed on the side surface of the fixed seat 200. A display screen 3371 is arranged on one side of the controller 337. An operation button 3372 installed on the surface of the controller 337 is arranged on one side of the display screen 3371;

[0047] When the angle of the device is offset by the provided connecting round block 3242, the first articulated rod 332 is driven to move in an arc. Since both ends of the second articulated rod 333 are articulated with the first articulated rod 332 and the horizontal push rod 334, when the second articulated rod 333 is horizontal, the horizontal push rod 334 drives the side sliding rod 313 to move towards the fixed seat 200 through the connecting plate 335. When the second articulated rod 333 tends to be vertical, the side sliding rod 313 is driven to move away from the fixed seat 200. When the patient's calf placement seat 340 drives the angle component 320 to move, the electric control component 330 drives the strength component 310 to move;

[0048] Moreover, when the first articulated rod 332 follows the offset, the transmitter 3321 will cooperate with the receiver group 331. The transmitter 3321 is the transmitting end. Multiple receiving ends are embedded inside the receiver group 331. The transmitter 3321 transmits signals to the adjacent receiving ends and transfers the signals to the controller 337. By analyzing the signals through the controller 337, when the patient has bradykinesia, the controller 337 drives the electric push rod 336 to drive the horizontal push rod 334 to move through the connecting plate 335 to assist the patient in exercise operations. When the patient is using it, the controller 337 can be controlled through the operation button 3372.

[0049] When the device is in use: When in use, the patient places the lower leg on the lower leg placement seat 340. The leg drives the lower leg placement seat 340 to swing, causing the connecting angle seat 322 to deviate in angle. The two arc-shaped sliding blocks 3215 of the sector gear ring 3221 are restricted by the limit screw rod 3216 to limit the rotation angle of the arc-shaped groove inside the sector gear 323. When the connecting round block 3242 deviates, it drives the first hinge rod 332 to move in an arc. Both ends of the second hinge rod 333 are hinged to the first hinge rod 332 and the transverse push rod 334. When the first hinge rod 332 follows the deviation, the transmitter 3321 will cooperate with the receiver group 331. The transmitter 3321 is the transmitting end, and multiple receiving ends are embedded and installed inside the receiver group 331. The transmitter 3321 emits signals to adjacent receiving ends and transmits the signals to the controller 337;

[0050] Through the analysis of the signals by the controller 337, the signal intervals received by multiple receiving ends will gradually lengthen during the patient's exercise. At this time, it indicates that the patient has bradykinesia. The controller 337 drives the electric push rod 336 to drive the transverse push rod 334 to move through the connecting plate 335 to assist the patient in the exercise operation. The connecting plate 335 drives the two side sliding rods 313 to slide inside the side groove 3115. The positioning rod 3114 slides inside the positioning groove 3113 and cooperates with the bolt positioning rod 3114 to position the position inside the positioning groove 3113, and adjusts appropriately according to the patient's leg length. The two connecting frames 311 are positioned to cooperate with the side sliding rods 313 to slide inside the side groove 3115 to maintain the stability of the sliding of the connecting seat 314. The middle rod 315 drives the piston 3151 to slide inside the middle hole 3111. Under the action of the piston 3151, the gas inside the middle hole 3111 is squeezed, and the gas inside the connecting frame 311 is discharged to the outside relatively slowly. When the elderly are undergoing rehabilitation exercises, relatively slow movements are formed.

[0051] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0052] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
