[0018] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0019] In the above solution, the patient can perform rehabilitation exercises by continuously pulling the resistance rope back and forth with the upper limb, and the resistance rope can be clamped by the first clamping plate. The clamping of the two first clamping plates can form a fixed resistance to the resistance rope. If the patient needs to adjust the magnitude of the resistance, the clamping assembly can be used to drive a plurality of second clamping plates so that the second clamping plates can clamp the resistance rope, thereby achieving the purpose of adjusting the resistance of the resistance rope, being able to adjust the magnitude of the force of the resistance rope of the device, improving the practicability of the device, and facilitating adaptation to the different magnitudes of force required by the patient during exercise;

[0020] By providing the first semi-circular plate and the second semi-circular plate, first install the first semi-circular plate on the surface of the resistance rope. Subsequently, flip the second semi-circular plate so that when the inner side of the second semi-circular plate fits with the inner side of the first semi-circular plate, the rectangular block is inserted into the rectangular groove on the first semi-circular plate. The first semi-circular plate facilitates the user to pull the resistance rope, improving the anti-slip property and stability of the user when using the resistance rope. Moreover, when the first semi-circular plate and the second semi-circular plate are installed, a plurality of fixing blocks are also driven to be positioned and inserted into the limiting grooves on the resistance rope, which can improve the stability of the first semi-circular plate and the second semi-circular plate during use, and avoid the surface of the resistance rope of the device becoming smooth during long-term use, resulting in a slipping phenomenon between the patient's hand and the resistance rope when the patient exercises and pulls the resistance rope;

[0021] When it is necessary to clean the resistance rope, inject the cleaning agent into the water inlet. The cleaning agent enters the storage tank through the water inlet and then flows onto the surface of the resistance rope through the drain holes. At the same time, pull the resistance rope. When the resistance rope is pulled, it drives the guide wheel to rotate. The rotation of the guide wheel can drive the second worm and the second worm gear, so that the limiting rod drives the gear to drive the first ring to rotate. The first ring drives the cleaning brush, and while the cleaning brush rotates, it can cooperate with the cleaning agent to clean the dust and impurities on the surface of the resistance rope, effectively removing microorganisms such as bacteria and viruses, reducing the risk of cross-infection, and improving the health of the user;

[0022] When the device is idle, pull the third ring. The third ring drives the L-shaped block to be removed from the L-shaped plate. Subsequently, pull the third ring downward so that the third ring drives the folding plate to move downward. When the third ring is pulled to align with the lower end of the limiting block, then insert the L-shaped block into the second limiting groove on the limiting block for restriction, facilitating the fixation of the folding plate, avoiding the aging of the resistance rope and causing damage to the resistance rope. Moreover, the folding plate can also prevent dust and impurities from adhering to the surface of the resistance rope when the device is not in use, and the service life of the device can be extended through the folding plate.

[0041] As Figures 1 to 9 shown, an embodiment of the present invention provides an upper limb functional exercise device for thoracic surgery care, including a main body unit 100;

[0042] The main body unit 100 includes a housing 101. A first limiting groove 102 is formed inside the housing 101. A power cord 103 is disposed in the first limiting groove 102. The power cord 103 includes a vertical section, a horizontal section, and an inclined section. The horizontal section and the inclined section are located in the first limiting groove 102, and the vertical section is located outside the first limiting groove 102. Three guide wheels 104 are rotatably connected to the inner wall of the first limiting groove 102 through a rotating shaft, and the three guide wheels 104 are drivingly connected through the power cord 103.

[0043] The adjusting unit 200 includes two first clamping plates 201. The two first clamping plates 201 are symmetrically and fixedly connected to the inner wall of the first limiting groove 102. A plurality of second clamping plates 202 are symmetrically and slidably connected to the inner wall of the first limiting groove 102. A connecting rod 203 is fixedly connected to the outer side of each of the plurality of second clamping plates 202. A semi-sphere 204 is fixedly connected to the outer side of the connecting rod 203. A clamping assembly 300 for adjusting the second clamping plates 202 is arranged on the inner wall of the first limiting groove 102.

[0044] By adopting the above technical solution, the patient can perform rehabilitation exercises by continuously pulling the power rope 103 back and forth with the upper limb. The first clamping plates 201 can clamp the power rope 103. The clamping of the two first clamping plates 201 can form a fixed resistance to the power rope 103. If the patient needs to adjust the magnitude of the resistance, the clamping assembly 300 can be used to drive the plurality of second clamping plates 202, so that the second clamping plates 202 can clamp the power rope 103, thereby achieving the purpose of adjusting the resistance of the power rope 103 and facilitating the adaptation to the different power requirements of the patient.

[0045] As Figure 2 and Figure 4 As shown, the clamping assembly 300 includes two rotating rods 301. The two rotating rods 301 are symmetrically and rotatably connected to the inner wall of the first limiting groove 102. A plurality of fan-shaped top blocks 302 are fixedly connected to the outer walls of the two rotating rods 301. The angular difference between adjacent two top blocks 302 is the same. The angle of the top block 302 closest to the first clamping plate 201 is zero, and the angles of the other top blocks 302 increase in turn along the direction away from the first clamping plate 201. The corresponding top blocks 302 are in contact with the corresponding semi-spheres 204. Magnets that attract each other are arranged in the top blocks 302 and the semi-spheres 204. A first worm gear 303 is fixedly connected to the middle of the rotating rod 301. A first worm 304 is rotatably connected to the inner wall of the first limiting groove 102. The first worm 304 rotatably penetrates through the outer shell 101. The thread directions of the left and right ends of the first worm 304 are opposite. The first worm 304 meshes with the first worm gear 303. Knobs 305 are fixedly connected to the left and right ends of the first worm 304.

[0046] By adopting the above technical solution, when it is necessary to adjust the resistance of the power cord 103, turn the knob 305, so that the knob 305 drives the first worm 304 to rotate. The first worm 304 drives two first worm wheels 303 to rotate simultaneously. Since the thread directions at the left and right ends of the first worm 304 are opposite, the two rotating rods 301 rotate in opposite directions. The rotating rod 301 drives the top block 302, causing the top block 302 to rotate. The rotation of the top block 302 can press the semi-sphere 204 to move, so that the semi-sphere 204 drives the connecting rod 203, and the connecting rod 203 drives the second clamping plate 202 to move inward. When the two second clamping plates 202 approach each other, they can clamp the power cord 103, thereby increasing the resistance of the power cord 103. The more the number of the second clamping plates 202 clamping the power cord 103, the greater the resulting resistance.

[0047] As Figure 4 and Figure 6 shown, first horizontal pieces 205 are fixedly connected to the inner sides of the two first clamping plates 201, second horizontal pieces 206 are fixedly connected to the inner sides of the plurality of second clamping plates 202, a sliding groove 207 that cooperates with the first horizontal pieces 205 and the second horizontal pieces 206 is formed in the power cord 103, the first horizontal pieces 205 are slidably connected in the sliding groove 207, and the plurality of second horizontal pieces 206 face the sliding groove 207.

[0048] By adopting the above technical solution, the position of the power cord 103 can be restricted by setting the first horizontal pieces 205, which is convenient for the subsequent second horizontal pieces 206 to clamp the power cord 103, and the first horizontal pieces 205 and the second horizontal pieces 206 can also prevent the power cord 103 from rotating.

[0049] As Figure 5 shown, a plurality of first semi-circular plates 208 are arranged on the outer side of the power cord 103, a second semi-circular plate 209 is rotatably connected to the inner sides of the plurality of first semi-circular plates 208, a rectangular block 210 is fixedly connected to the inner side of the second semi-circular plate 209, a rectangular groove 211 that cooperates with the rectangular block 210 is formed in the first semi-circular plate 208, mounting membranes 212 are fixedly connected to the outer sides of the first semi-circular plate 208 and the second semi-circular plate 209, the mounting membranes 212 both face the sliding groove 207, a limiting component 400 for restricting the rectangular block 210 is arranged in the middle of the first semi-circular plate 208, and the two ends of the first horizontal pieces 205 and the second horizontal pieces 206 are both rounded.

[0050] By adopting the above technical solution, during use, the first semi-circular plate 208 is installed on the surface of the power rope 103. Subsequently, the second semi-circular plate 209 is flipped so that when the inner sides of the second semi-circular plate 209 and the first semi-circular plate 208 are mutually attached, the rectangular block 210 is inserted into the rectangular groove 211 on the first semi-circular plate 208. The first semi-circular plate 208 facilitates the user to pull the power rope 103, improving the anti-slip property and stability of the user when using the power rope 103.

[0051] As Figure 5 and Figure 6 shown, a plurality of fixing blocks 213 are fixedly connected to the inner sides of the first semi-circular plate 208 and the second semi-circular plate 209, and a plurality of limiting grooves 214 that cooperate with the fixing blocks 213 are formed on the power rope 103.

[0052] By adopting the above technical solution, when the first semi-circular plate 208 and the second semi-circular plate 209 are installed, a plurality of fixing blocks 213 are driven to be positioned and inserted into the limiting grooves 214 on the power rope 103, which can improve the stability of the first semi-circular plate 208 and the second semi-circular plate 209 during use.

[0053] As Figure 5 shown, the limiting component 400 includes a sliding block 401. A guiding groove 402 is formed in the middle of the first semi-circular plate 208. The sliding block 401 is slidably connected to the inner wall of the guiding groove 402. The upper end of the sliding block 401 is fixedly connected to a sliding rod 403. The sliding rod 403 is slidably inserted through the first semi-circular plate 208. A spring 404 is fixedly connected between the inner top wall of the guiding groove 402 and the sliding block 401. The spring 404 is in a stretched state and is wound around the outer side of the sliding rod 403. The lower end of the sliding block 401 is fixedly connected to a plug pin 405. A slot that cooperates with the plug pin 405 is formed in the mounting film 212. The upper end of the sliding rod 403 is fixedly connected to a pulling block 406.

[0054] By adopting the above technical solution, when it is necessary to disassemble the first semi-circular plate 208 and the second semi-circular plate 209, pull the pulling block 406, so that the pulling block 406 drives the sliding rod 403, and the sliding rod 403 drives the sliding block 401 to move upward, causing the spring 404 to be compressed. While the sliding block 401 moves upward, it drives the plug pin 405 to leave the slot on the rectangular block 210, and the rectangular block 210 is released from the restriction. Subsequently, flip the second semi-circular plate 209 and remove the second semi-circular plate 209 and the first semi-circular plate 208 from the power rope 103, which is convenient for the installation and disassembly of the first semi-circular plate 208 and the second semi-circular plate 209.

[0055] As Figure 7As shown, a first ring 215 is rotatably connected to the inner wall of the first limiting groove 102. A cleaning brush 216 is fixedly connected to the inner side of the first ring 215. The force rope 103 slidably penetrates through the middle of the cleaning brush 216. An inlet 217 is fixedly connected to the upper end of the first ring 215. The inlet 217 rotatably penetrates through the housing 101. A storage groove 218 is formed in the middle of the first ring 215. A plurality of drain holes 219 are formed in the inner wall of the storage groove 218. A driving assembly 500 for driving the cleaning brush 216 is arranged on the first ring 215.

[0056] By adopting the above technical solution, the cleaning agent is injected into the inlet 217, enters the storage groove 218 on the first ring 215 through the inlet 217, and then flows out to the force rope 103 through the drain holes 219. Cooperating with the cleaning brush 216, the dust and impurities on the force rope 103 can be cleaned, the bacteria, viruses and other microorganisms can be effectively removed, the risk of cross-infection can be reduced, and the health of the users can be improved.

[0057] As Figure 8 shown, the driving assembly 500 includes a toothed ring 501. The toothed ring 501 is fixedly connected to the outer side of the first ring 215. A second worm 502 is fixedly connected to the right end of the guide wheel 104. A limiting rod 503 is rotatably connected to the inner wall of the first limiting groove 102. A second worm gear 504 is fixedly connected to the limiting rod 503. The second worm gear 504 cooperates with the second worm 502. A gear 505 is fixedly connected to the limiting rod 503. The gear 505 meshes with the toothed ring 501.

[0058] By adopting the above technical solution, during use, when the force rope 103 is pulled, the guide wheel 104 is driven while the force rope 103 rotates, so that the guide wheel 104 drives the second worm 502. The second worm 502 drives the second worm gear 504 to rotate, so that the second worm gear 504 drives the limiting rod 503 to rotate. While the limiting rod 503 rotates, the gear 505 is driven, so that the gear 505 drives the toothed ring 501, and the toothed ring 501 drives the first ring 215 to rotate, so that the first ring 215 drives the cleaning brush 216 to clean the force rope 103.

[0059] As Figure 9 shown, a second ring 220 is fixedly connected to the housing 101. A folding plate 221 is fixedly connected to the lower end of the second ring 220. A third ring 222 is fixedly connected to the lower end of the folding plate 221. The force rope 103 slidably penetrates through the middle of the second ring 220, the folding plate 221 and the third ring 222.

[0060] By adopting the above technical solution, the folding plate 221 can protect the power cord 103, avoid the aging phenomenon of the power cord 103, and thus improve the service life of the power cord 103.

[0061] As Figure 1 and Figure 9 shown, symmetrically fixed to the left and right ends of the third ring 222 are L-shaped blocks 223. The L-shaped blocks 223 are made of rubber material. Symmetrically fixed to the front end of the outer shell 101 are L-shaped plates 224. The L-shaped blocks 223 are engaged with the L-shaped plates 224. Symmetrically fixed to the front end of the outer shell 101 are limit blocks 225. A second limit groove 226 is formed in the middle of the limit block 225.

[0062] By adopting the above technical solution, when the device is idle, pull the third ring 222. The third ring 222 drives the L-shaped block 223 to be removed from the L-shaped plate 224. Subsequently, pull the third ring 222 downward so that the third ring 222 drives the folding plate 221 to move downward. When the third ring 222 is pulled to align with the lower end of the limit block 225, then insert the L-shaped block 223 into the second limit groove 226 on the limit block 225 for restriction, which is convenient for fixing the folding plate 221.

[0063] The working process provided by the present invention is as follows:

[0064] When the present invention is in use, first, the patient can perform rehabilitation exercises by continuously pulling the power cord 103 back and forth with the upper limb. If the patient needs to adjust the resistance of the power cord 103, turn the knob 305, so that the knob 305 drives the first worm 304 to rotate. The first worm 304 drives two first worm wheels 303 to rotate simultaneously. Since the thread directions at the left and right ends of the first worm 304 are opposite, the two rotating rods 301 rotate in opposite directions. The rotating rod 301 drives the top block 302, causing the top block 302 to rotate. The rotation of the top block 302 can compress the semi-sphere 204 to move, so that the semi-sphere 204 drives the connecting rod 203, and the connecting rod 203 drives the second clamping plate 202 to move inward. When the two second clamping plates 202 approach each other, they can clamp the power cord 103, thereby increasing the resistance of the power cord 103. The more the second clamping plates 202 clamp the power cord 103, the greater the resistance caused, so as to achieve the purpose of adjusting the resistance of the power cord 103 and facilitate adapting to different strength requirements of the patient. When it is necessary to reduce the resistance to the power cord 103, turn the knob 305 in the reverse direction, so that the knob 305 drives the first worm 304 to rotate. Since there are magnets attracting each other in the top block 302 and the semi-sphere 204, the second clamping plate 202 is released from the restriction on the power cord 103. And the first semi-circular plate 208 and the second semi-circular plate 209 on the power cord 103 can improve the stability of the patient when using the power cord 103 and avoid slipping between the patient's hand and the power cord 103. When it is necessary to disassemble the first semi-circular plate 208 and the second semi-circular plate 209, pull the pull block 406, so that the pull block 406 drives the sliding rod 403, and the sliding rod 403 drives the sliding block 401 to move upward, compressing the spring 404. When the sliding block 401 moves upward, it drives the pin 405 to leave the slot on the rectangular block 210, and the rectangular block 210 is released from the restriction. Then, flip the second semi-circular plate 209 and remove the second semi-circular plate 209 and the first semi-circular plate 208 from the power cord 103, which is convenient for disassembling and replacing the first semi-circular plate 208 and the second semi-circular plate 209. When it is necessary to clean the power cord 103, inject the cleaning agent into the water inlet 217. The cleaning agent enters the storage tank 218 on the first ring 215 through the water inlet 217 and then flows out to the power cord 103 through the drain holes 219. At the same time, pull the power cord 103. When the power cord 103 rotates, it drives the guide wheel 104, so that the guide wheel 104 drives the second worm 502, and the second worm 502 drives the second worm wheel 504 to rotate, so that the second worm wheel 504 drives the limiting rod 503 to rotate. When the limiting rod 503 rotates, it drives the gear 505, so that the gear 505 drives the toothed ring 501, and the toothed ring 501 drives the first ring 215 to rotate, so that the first ring 215 drives the cleaning brush 216 to rotate. And when the cleaning brush 216 rotates, it can cooperate with the cleaning agent to clean the dust and impurities on the surface of the power cord 103.It can effectively remove microorganisms such as bacteria and viruses from the power rope 103 and reduce the risk of cross-infection. When the device is idle, pull the third ring 222. The third ring 222 drives the L-shaped block 223 to be removed from the L-shaped plate 224. Subsequently, pull the third ring 222 downward so that the third ring 222 drives the folding plate 221 to move downward. When the third ring 222 is pulled to align with the lower end of the limit block 225, then insert the L-shaped block 223 into the second limit groove 226 on the limit block 225 for restriction, which is convenient for fixing the folding plate 221, avoiding the aging of the power rope 103, and the folding plate 221 can also prevent dust and impurities from adhering to the surface of the power rope 103 when the device is not in use.
