[0013] Optionally, the support column has multiple through holes along the vertical direction, and the second locking pin passes through one of the through holes.

[0014] Optionally, the leg training assembly further includes a locking bolt and a pin. One end of the pin passes through the first lifting column, and the other end of the pin is configured as a multi-faceted column structure. The rotating frame has polygonal holes so that the pin can be fitted into the polygonal holes. The locking bolt is screwed onto the pin so that the locking bolt and the pin together clamp the rotating frame.

[0015] Optionally, the rotating frame includes a frame body and a crossbar, the polygonal hole is located on one end of the frame body, and the crossbar is vertically arranged on the side of the frame body away from the first lifting column.

[0016] Optionally, the rotating frame further includes multiple counterweights, and the frame body has multiple counterweight holes, with each counterweight detachably inserted into each of the counterweight holes.

[0017] Optionally, the arm training component includes a second lifting column, a horizontal arm, a telescopic rope, and a pull ring.

[0033] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention.

[0034] like Figure 1 and Figure 2As shown, a detachable rehabilitation training device 10 includes a base 100, a training mechanism 200, and a chair 300. The base 100 is provided with four fixed seats 400. In one of the fixed seats 400, a retractable first locking post 410 is provided on the side wall of the fixed seat 400. The training mechanism 200 includes four pillars 210, two symmetrically arranged leg training components 220, and two symmetrically arranged arm training components 230. One end of each pillar 210 is inserted into each fixed seat 400, and each first locking post 410 passes through each pillar 210. The two leg training components 220 are detachably mounted on two of the pillars 210, and the two arm training components 230 are detachably mounted on the other two pillars 210. The chair 300 is detachably mounted on the base 100, and the two arm training components 230 are located on both sides of the chair 300, and the two leg training components 220 are located on the front side of the chair 300.

[0035] Specifically, multiple fixing seats 400 are installed on the base 100, with a gap between each of the four fixing seats 400. Further, a retractable first locking post 410 is provided on the side wall of each fixing seat 400. Further, four support pillars 210 are detachably inserted into the four fixing seats 400. Specifically, after the four support pillars 210 are inserted into the four fixing seats 400, the first locking posts 410 on the four fixing seats 400 pass through the four support pillars 210 respectively, so that the support pillars 210 are locked and fixed to the corresponding fixing seats 400. Further, two leg training components 220 are respectively installed on the two support pillars 210 located on the front side, and two arm training components 230 are respectively installed on the two support pillars 210 located on the rear side. The leg training components 220 are used for leg rehabilitation training, and the arm training components 230 are used for arm rehabilitation training. The chair 300 is detachably mounted on the base 100 and is positioned between the two leg training components 220 and the two arm training components 230. The two leg training components 220 are located at the front of the chair 300, and the two arm training components 230 are located on either side of the chair 300. By detachably mounting the chair 300, the two leg training components 220, the two arm training components 230, and the support column 210, compared to the existing integrated structure of rehabilitation training chairs, it can be disassembled into several parts for storage when not in use, thus saving space and making it more convenient to use. Furthermore, as the chair 300 is a detachable structure, it is not fixed, allowing users to choose a suitable seat according to the actual situation. This reduces the weight of the seat during transport, thereby reducing the overall weight of the rehabilitation training device, allowing users to move it at any time.

[0036] Preferably, the fixing seat 400 is fixed to the base 100 by welding, thus ensuring sufficient structural strength between the fixing seat 400 and the base 100.

[0037] like Figure 3 As shown, optionally, a push-out spring 420 is provided inside the fixing seat 400. The two ends of the push-out spring 420 abut against the first locking post 410 and the fixing seat 400 respectively, so that one end of the first locking post 410 protrudes from the outer side wall of the fixing seat 400.

[0038] Specifically, in order to make the first locking post 410 tend to protrude from the outer wall of the fixing seat 400 in its natural state, an ejection spring 420 is installed in the fixing seat 400 to push the first locking post 410, so that the first locking post 410 protrudes from the outer wall of the fixing seat 400 to lock the support post 210.

[0039] like Figure 1 and Figure 2 As shown, optionally, the leg training component 220 includes a first lifting column 221 and a rotating frame 222. One end of the first lifting column 221 is inserted through the support column 210. A retractable second locking column is provided inside the first lifting column 221. The second locking column is used to insert the support column 210. One end of the rotating frame 222 is rotatably mounted on the first lifting column 221. The other end of the rotating frame 222 falls naturally under its own weight.

[0040] Specifically, one end of the first lifting column 221 is inserted into the support column 210. A retractable second locking column is provided inside the first lifting column 221; for example, the second locking column has the same structure as the first locking column 410. For example, a spring is also installed inside the first lifting column 221, which pushes the second locking column, causing it to protrude from the outer wall of the first lifting column 221 in its natural state. Thus, after the first lifting column 221 is inserted into the support column 210, the second locking column will pass laterally through the support column 210 for fixation. This achieves a detachable installation structure between the first lifting column 221 and the support column 210, and between the support column 210 and the fixing base 400. The end of the rotating frame 222 away from the first lifting column 221 naturally falls under its own weight. Thus, the user can lift the end of the rotating frame 222 away from the first lifting column 221 with the instep of their foot to perform leg rehabilitation training.

[0041] like Figure 1 and Figure 2 As shown, optionally, the support column 210 has multiple through holes 211 along the vertical direction, and the second locking column passes through one of the through holes 211.

[0042] Specifically, to enable individuals of different leg lengths to use the detachable rehabilitation training device 10 of this application for rehabilitation training, the height of the first lifting column 221 relative to the support column 210 is adjustable. Specifically, multiple through holes 211 are vertically formed on the outer wall of the support column 210, allowing the first lifting column 221 to be inserted into a designated position on the support column 210 as needed, and then the second locking column to pass through the corresponding through hole 211. Furthermore, it should be noted that the insertion structure between the first lifting column 221 and the support column 210 also achieves the purpose of detachable installation.

[0043] like Figure 1 and Figure 2 As shown, optionally, the leg training component 220 also includes a locking bolt 224 and a pin 225. One end of the pin 225 passes through the first lifting column 221, and the other end of the pin 225 is configured as a multi-faceted column structure. The rotating frame 222 has polygonal holes so that the pin 225 can be inserted into the polygonal holes. The locking bolt 224 is screwed onto the pin 225 so that the locking bolt 224 and the pin 225 together clamp the rotating frame 222.

[0044] Specifically, one end of the pin 225 passes through the first lifting column 221. For example, a bearing is installed on the first lifting column 221, allowing the pin 225 to pass through the bearing and rotate relative to the first lifting column 221. Furthermore, to fix the pin 225 and the rotating frame 222 as a single unit, a multi-faceted column structure is incorporated into part of the pin 225. A matching polygonal hole is formed in the rotating frame 222, and the multi-faceted column structure of the pin 225 is inserted into the polygonal hole of the rotating frame 222. Finally, a locking bolt 224 is screwed onto the pin 225, so that the locking bolt 224 and the pin 225 together clamp the rotating frame 222, thus fixing the rotating frame 222 and the pin 225 as a single unit.

[0045] like Figure 1 and Figure 2 As shown, optionally, the rotating frame 222 includes a frame body 2221 and a crossbar 2222. The polygonal hole is located on one end of the frame body 2221, and the crossbar 2222 is vertically arranged on the side of the frame body 2221 away from the first lifting column 221.

[0046] Specifically, one end of the frame 2221 is fixed to the pin 225, and the other end of the frame 2221 hangs down naturally, with the crossbar 2222 located on the hanging end of the frame 2221. Thus, the crossbar 2222 facilitates the user's instep applying lifting force to it. In one embodiment, the frame 2221 and the crossbar 2222 are integrally formed, for example, the frame 2221 and the crossbar 2222 are fixed by welding.

[0047] like Figure 1 and Figure 2 As shown, optionally, the rotating frame 222 also includes multiple counterweights 2223, and the frame body 2221 has multiple counterweight holes, with each counterweight 2223 detachably inserted into each counterweight hole.

[0048] It should be noted that the counterweight 2223 is detachably mounted on the frame 2221. This allows users to add the number of counterweights 2223 according to their specific rehabilitation needs, thereby setting the rotating frame 222 to a suitable weight and better enabling the legs to undergo rehabilitation training.

[0049] like Figure 1 and Figure 2 As shown, optionally, the rotating frame 222 also includes a handle 2224, which is located on the end of the frame 2221 away from the crossbar 2222. Thus, when a user is performing leg rehabilitation training, if the weight of the frame 2221 is too great, they can apply a gripping force to the handle 2224, thereby reducing pressure on the legs and making it easier to use.

[0050] like Figure 1 , Figure 2 and Figure 4 As shown, optionally, the arm training component 230 includes a second lifting column 231, a horizontal arm 232, a telescopic rope 233, and a pull ring 234. One end of the second lifting column 231 is threaded onto the support column 210. A retractable third locking post is provided inside the second lifting column 231 for threading the support column 210. One end of the horizontal arm 232 is located on the second lifting column 231, and the other end of the horizontal arm 232 extends horizontally toward the leg training component 220. One end of the telescopic rope 233 is connected to the second lifting column 231, and the other end of the telescopic rope 233 passes through the horizontal arm 232. The pull ring 234 is located on the end of the horizontal arm 232 away from the second lifting column 231, and the pull ring 234 is connected to the other end of the telescopic rope 233.

[0051] Specifically, the second lifting column 231 is inserted into the top of the support column 210. A retractable third locking post is installed within the second lifting column 231, allowing the third locking post to pass through the side wall of the support column 210. This enables the second lifting column 231 to be detachably mounted on the support column 210. Furthermore, since the support column 210 has multiple through holes 211 along the vertical direction, by having the third locking post pass through one of these holes 211, the height of the second lifting column 231 relative to the support column 210 can be adjusted. This allows the arm training component 230 to be adjusted to a specified height to accommodate users of different heights. Moreover, the second lifting column 231 and the support column 210 are detachably mounted, allowing them to be disassembled into parts for easy storage when not in use. Finally, a horizontal arm 232 is mounted on the second lifting column 231, extending horizontally. One end of the telescopic rope 233 is fixed to the inner wall of the second lifting column 231, and the other end passes through the horizontal arm 232 and is connected to the pull ring 234 located at the front end of the horizontal arm 232. Thus, by pushing or pulling the pull ring 234, the user causes the telescopic rope 233 to deform under force, thereby achieving rehabilitation training for the arm. It should be noted that the telescopic rope 233 is a rope with elastic tension; for example, it is a rubber band structure.

[0052] like Figure 4 and Figure 5 As shown, optionally, the arm training assembly 230 also includes a sleeve post 236, a reversing post 237, and a lifting spring 238. The sleeve post 236 is disposed on the second lifting post 231, and the sleeve post 236 has a plurality of first slots 2361 circumferentially opened. The reversing post 237 is disposed on the cross arm 232, and a limit post 239 is provided on the outer side wall of the reversing post 237. The reversing post 237 is inserted into the sleeve post 236. The lifting spring 238 is located inside the sleeve post 236, and the lifting spring 238 abuts against the sleeve post 236 and the reversing post 237 respectively, so that the limit post 239 is located in one of the first slots 2361.

[0053] Specifically, to allow users to better target different muscles in their arms for stretching exercises, the horizontal arm 232 is designed with an adjustable angle. Specifically, the sleeve post 236 is mounted on top of the second lifting post 231, and the reversing post 237 is mounted on the bottom of the horizontal arm 232. The sleeve post 236 has multiple first slots 2361 circumferentially formed, and a limiting post 239 is provided on the outer wall of the reversing post 237. Furthermore, a lifting spring 238 is installed inside the sleeve post 236, with both ends of the lifting spring 238 abutting against the sleeve post 236 and the reversing post 237 respectively. Thus, under the elastic thrust of the lifting spring 238, the reversing post 237 tends to rise, causing the limiting post 239 on the outer wall of the reversing post 237 to fall into one of the first slots 2361. Thus, when it is necessary to adjust the angle of the horizontal arm 232 relative to the second lifting column 231, a downward pressure is applied to the horizontal arm 232, causing the limiting column 239 to disengage from the first slot 2361. Then, a horizontal thrust is applied to the horizontal arm 232, causing the horizontal arm 232 to rotate around the sleeve column 236 until the horizontal arm 232 rotates to the designated position. After that, the downward pressure applied to the horizontal arm 232 is released, causing the limiting column 239 to fall back into the new first slot 2361 to achieve repositioning.

[0054] like Figure 4 , Figure 6 and Figure 7 As shown, optionally, the boom 232 includes a boom 2321, a carriage 2322, and a rocker arm 2323. A fourth locking post is provided inside the reversing column 237. A collar 2324 is provided on the boom 2321. The collar 2324 is sleeved on the reversing column 237 so that the fourth locking post passes through the collar 2324. Multiple second locking slots 23211 are opened in the boom 2321 along the horizontal direction. The carriage 2322 is slidably disposed inside the boom 2321. The rocker arm 2323 is rotatably disposed on the carriage 2322. A locking post 2325 is provided on the rocker arm 2323. The rocker arm 2323 is used to drive the locking post 2325 to be accommodated in one of the second locking slots 23211 so that the carriage 2322 and the boom 2321 are relatively fixed.

[0055] Specifically, a collar 2324 is installed at the bottom of the boom 2321, and a retractable fourth locking pin is installed inside the reversing column 237. Thus, when the collar 2324 is fitted onto the reversing column 237, the fourth locking pin passes through the collar 2324, securing the collar 2324 and the reversing column 237 together, thereby allowing the boom 2321 and the reversing column 237 to be detachably installed and fixed. Multiple sliding grooves are formed inside the boom 2321, and multiple second locking slots 23211 are formed on the inner wall of the sliding grooves. When the slide 2322 can slide within the sliding grooves, one end of the rocker arm 2323 is rotatably mounted on the slide 2322. A locking pin 2325 is provided on the rocker arm 2323, for example, the locking pin 2325 can be fixed to the rocker arm 2323 by welding. Thus, under its own weight, the rocker arm 2323 causes the locking post 2325 to engage with one of the second locking slots 23211. Because the inner wall of the second locking slot 23211 engages with the locking post 2325, the carriage 2322 cannot continue to slide along the groove of the boom 2321. It should be noted that the pull ring 234 is located at the front end of the carriage 2322. Thus, by setting an adjustable front-to-back position of the carriage 2322 relative to the boom 2321, the starting position of the pull ring 234 on the crossarm 232 is adjustable, thus adapting to users with different arm lengths and providing greater compatibility.

[0056] like Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, optionally, the arm training component 230 also includes a winding coil 2311, a ratchet 2312, and a pawl 2313. The winding coil 2311 is rotatably disposed inside the second lifting column 231. The ratchet 2312 is concentrically fixed with the winding coil 2311. One end of the pawl 2313 is rotatably disposed on the inner side wall of the second lifting column 231, and the other end of the pawl 2313 abuts against the ratchet 2312. One end of the telescopic rope 233 is wound around the winding coil 2311.

[0057] It should be noted that the winding coil 2311 is mounted inside the second lifting column 231 via a rotating shaft. The ratchet 2312 is coaxially mounted on one end of the winding coil 2311, and the pawl 2313 is rotatably mounted on the inner wall of the second lifting column 231, with one end of the pawl 2313 engaging a tooth of the ratchet 2312. Thus, by engaging the ratchet 2312 with the pawl 2313, the ratchet 2312 can only rotate in one direction. By rotating the ratchet 2312, the winding coil 2311 is driven to rotate, allowing the telescopic rope 233 to be wound around or released from the winding coil 2311. When the telescopic rope 233 is wound around the winding coil 2311, the tension of the telescopic rope 233 is increased, which in turn increases the tensile force of the pull ring 234. Therefore, users can adjust the tension of the pull ring 234 according to their actual needs, thereby enabling better rehabilitation training of the arm.

[0058] like Figure 4 As shown, in one embodiment, a first roller 2326 is rotatably provided at the end of the carriage 2322 near the pull ring 234, and a second roller 2327 is provided at the end of the boom 2321 near the collar 2324, so that the telescopic rope 233 passes through the second roller 2327 and the first roller 2326 in sequence.

[0059] It should be noted that since the telescopic rope 233 needs to make multiple turns after being pulled out from the winding coil 2311 before being fixed to the pull ring 234, in order to avoid friction between the telescopic rope 233 and components such as the boom 2321 and the slide 2322, a first roller 2326 is installed at the front end of the slide 2322 via a bearing, and a second roller 2327 is installed at the position of the boom 2321 near the collar 2324. This allows the telescopic rope 233 to change direction through the first roller 2326 and the second roller 2327, thus preventing wear between the telescopic rope 233 and the boom 2321, the slide 2322, etc.

[0060] In one embodiment, the fourth, third, and second locking pins are structurally identical to the first locking pin 410. Specifically, the first locking pin 410 protrudes from the outer wall of the fixing base 400 under the elastic thrust of the ejector spring 420. Therefore, the fourth, third, and second locking pins are each equipped with a spring for pushing, causing the second, third, and fourth locking pins to protrude and lock under the elastic thrust.

[0061] like Figure 1 and Figure 2 As shown, in one embodiment, the base 100 includes two folding plates 110, the sides of which are hinged together. Two fixing seats 400 are located on one of the two folding plates 110, and the other two fixing seats 400 are located on the other of the two folding plates 110. In this way, the base 100 can be folded for storage, further reducing the space it occupies.
