Description

Technical Field

[0001] This invention relates to the field of rehabilitation exercise technology, specifically to a resistance training device for patients with chronic kidney disease. Background Technology

[0002] Chronic kidney disease (CKD) is a chronic structural and functional disorder of the kidneys caused by various factors (with a history of kidney damage lasting more than 3 months). This includes pathological damage with normal or abnormal renal glomerular filtration rate (GFR), abnormal blood or urine composition, abnormal imaging findings, or an unexplained decrease in GFR (<60 ml / min·1.73 m²) for more than 3 months. Diseases that cause CKD include various primary and secondary glomerulonephritis, renal tubular injury, and renal vascular diseases. In rehabilitation exercises for CKD, limb exercises are particularly important.

[0003] Currently, most exercises for patients' limbs involve resistance training, with common exercises including weightlifting, cycling, and sit-ups. When performing weightlifting, the weight needs to be adjusted according to the patient's rehabilitation stage. Existing weightlifting devices mostly change the weight by adding or removing weights, but this method requires repeated loading and unloading of weights, which is not only cumbersome but also prone to causing weights to fall and injure the user, reducing the device's safety. Therefore, to address these technical problems, a resistance training device for patients with chronic kidney disease is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a resistance training device for patients with chronic kidney disease, which allows for easy adjustment of lifting weights and improves the safety of device use.

[0005] A resistance training device for patients with chronic kidney disease includes: a base and an exercise mechanism. Two sets of uprights are spaced apart on the base, each set of uprights is equipped with a mounting base, and mounting frames are connected to the two sets of mounting bases. The exercise mechanism includes:

[0006] The lifting rod has two ends that can be slidably mounted on the mounting frame along the height direction of the base;

[0007] A mounting plate is provided on the lifting rod;

[0008] The first spring is provided at both ends of the mounting plate with multiple sets of first springs detachably arranged at intervals. The mounting bracket has multiple sets of through holes corresponding to the multiple sets of first springs, and the multiple sets of first springs can pass through the multiple sets of through holes.

[0009] The first adjustment mechanism includes two sets of baffles and a first drive assembly. The two sets of baffles are slidably disposed on the mounting frame along the length direction of the base and can sequentially block or open multiple sets of through holes. The first drive assembly is disposed on the mounting frame and connected to the two sets of baffles. The first drive assembly is used to drive the two sets of baffles to slide.

[0010] The beneficial effects of the above-mentioned resistance training device for patients with chronic kidney disease are as follows:

[0011] Weightlifting exercises can be performed by gripping the lifting bar and sliding it up and down with the upper limbs. When the weight needs to be adjusted, the first drive assembly drives two sets of baffles to slide, which block the through holes. At this time, when the lifting bar moves upward, it drives multiple sets of first springs to move upward through the mounting plate. The upward movement of the first springs causes the first spring corresponding to the blocked through hole to abut against the baffle. This increases the force required for the lifting bar to move upward. By controlling the sliding of the two sets of baffles to change the number of blocked through holes, the corresponding number of first springs can abut against the two sets of baffles. This makes it easy to change the weight according to the patient's needs. Changing the weight is convenient and does not require disassembling the first springs, thus improving the safety of the device.

[0012] In one embodiment, the first drive assembly includes a bidirectional screw, two sets of synchronous pulleys, and a synchronous belt. The mounting bracket has guide grooves extending through multiple sets of through holes. Two sets of baffles are slidably disposed within the guide grooves. The bidirectional screw is rotatably disposed within the guide grooves, with both ends threadedly connected to the two sets of baffles. One set of synchronous pulleys is coaxially disposed on the bidirectional screw, and the other set of synchronous pulleys is rotatably disposed on the mounting bracket, close to the mounting base. The two sets of synchronous pulleys are connected by the synchronous belt. By rotating the synchronous pulley close to the mounting base, this rotation drives the other set of synchronous pulleys to rotate via the synchronous belt, which in turn drives the bidirectional screw to rotate. The rotation of the bidirectional screw, in conjunction with the threaded engagement of the two sets of baffles, drives the two sets of baffles to slide, making the sliding of the two sets of baffles convenient. Stopping the rotation of the synchronous pulleys stops the rotation of the bidirectional screw, and stopping the rotation of the bidirectional screw fixes the two sets of baffles, making the fixation of the two sets of baffles convenient.

[0013] In one embodiment, the exercise device further includes a fall protection component, the fall protection component comprising:

[0014] The lifting rod has mounting grooves at both ends, and the locking blocks are slidably disposed in both sets of mounting grooves. The mounting frame has locking slots at both ends, and multiple sets of locking slots are spaced apart along the height direction of the base. One end of each set of locking blocks can pass through the locking slot.

[0015] The second spring connects the other end of both sets of locking blocks to the side wall of the mounting groove via the second spring.

[0016] A pressing assembly is disposed on the lifting rod and connected to the two sets of locking blocks. The pressing assembly is used to drive the two sets of locking blocks to move closer together so that the two sets of locking blocks are separated from the locking groove.

[0017] In one embodiment, the pressing component includes:

[0018] The pressure rod has multiple sets of connecting shafts spaced apart. The multiple sets of connecting shafts can slide through the lifting rod radially and are limited by a limiting knob. Both ends of the pressure rod are provided with abutment rods. Both sets of locking blocks are provided with inclined surfaces. The bottom ends of the two sets of abutment rods contact the two sets of inclined surfaces respectively.

[0019] The third spring is sleeved on each of the multiple connecting shafts, with its two ends abutting against the pressure rod and the lifting rod, respectively. When holding the lifting rod, pressure is applied to the pressure rod with the fingers, causing it to move closer to the lifting rod. At this time, the third spring is compressed and contracts, and the moving abutment pushes against the inclined surface, causing the locking block to move and separate from the locking groove. Simultaneously, the second spring is compressed and contracts, and the separation of the locking block from the locking groove releases the locking of the lifting rod. At this point, force can be applied to move the lifting rod up and down for weightlifting. When the hand slips off the lifting rod, the lifting rod moves downward under the force of gravity and the reaction force of the first spring. At the same time, the pressure on the pressure rod disappears, and the reaction force of the third spring causes the pressure rod to move in the opposite direction and reset. The reverse movement of the pressure rod causes the abutment to release the pressure on the inclined surface. At this point, the reaction force of the second spring drives the locking block to move in the opposite direction. When the lifting rod moves downward and the locking block aligns with the locking groove, the locking block passes through the locking groove and fixes the lifting rod, thereby preventing the lifting rod from falling and injuring the user, and improving the safety of the device.

[0020] In one embodiment, the exercise mechanism further includes a second adjustment mechanism, the second adjustment mechanism comprising:

[0021] An adjustment component is provided, wherein the mounting frame is connected to two sets of mounting seats via the adjustment component, and the adjustment component can drive the mounting frame to rotate so that both ends of the mounting frame are perpendicular to the column;

[0022] A pressure plate is located between the lifting rod and the mounting plate. Both ends of the pressure plate are provided with connecting sleeves, and two sets of the connecting sleeves are fitted onto the lifting rod.

[0023] A transmission assembly connects the column, the mounting bracket, and the connecting sleeve. Rotation of the mounting bracket drives the pressure plate to rotate via the transmission assembly, positioning the lifting rod between the pressure plate and the mounting plate. By adjusting the mounting bracket, the two ends of the mounting bracket are made perpendicular to the column, and the pressure plate is rotated via the transmission assembly, positioning the lifting rod between the pressure plate and the mounting plate. At this point, the patient can support their upper limbs on the pressure plate to perform wall push-ups. By changing the resistance training method, the device can be used by different patients, improving its practicality.

[0024] In one embodiment, the adjusting assembly includes a worm gear and a worm. One end of the mounting bracket has a first fixing hole, and the other end has a first fixing shaft. One set of mounting seats has a second fixing shaft, and another set has a second fixing hole. The first fixing hole is fitted onto the second fixing shaft, and the first fixing shaft passes through the second fixing hole. The worm gear is coaxially mounted on the first fixing shaft. The worm is rotatably mounted on the mounting seat and meshes with the worm gear. By rotating the worm, the worm meshes with the worm gear, driving the worm gear to rotate. The rotation of the worm gear drives the first fixing shaft to rotate, which in turn drives the mounting bracket to rotate. This facilitates driving the mounting bracket to rotate. Furthermore, by stopping the rotation of the worm, the worm stops rotating and engages with the worm gear, thus fixing the worm gear and the mounting bracket. This makes fixing the mounting bracket convenient.

[0025] In one embodiment, the transmission assembly includes a drive shaft, a telescopic shaft, a first gear, a second gear, a first bevel gear, and a second bevel gear. The drive shaft is rotatably mounted on the mounting bracket, and the telescopic shaft is rotatably mounted on the lifting rod, with one end slidably passing through the drive shaft. The first gear is rotatably mounted on the mounting bracket, and the second gear is mounted on the second fixed shaft and meshes with the first gear. The number of teeth of the second gear is twice that of the first gear. The first gear and the drive shaft are both coaxially mounted with the first bevel gear, and two sets of the first bevel gears mesh. The telescopic shaft and one set of the connecting sleeves are both coaxially mounted with the second bevel gear, and two sets of the second bevel gears mesh. When the mounting frame rotates, it drives the first gear to rotate around the second gear. Since the first gear and the second gear mesh, the first gear rotates. The rotation of the first gear drives the transmission shaft to rotate through the meshing of two sets of first bevel gears. The rotation of the transmission shaft drives the telescopic shaft to rotate. The rotation of the telescopic shaft drives the connecting sleeve to rotate through the meshing of two sets of second bevel gears. The rotation of the connecting sleeve drives the pressure plate to rotate. Driving the pressure plate to rotate is convenient and allows the device to quickly switch the exercise mode.

[0026] In one embodiment, a limiting block is provided on the drive shaft along its axial direction, and a limiting groove is formed on the periphery of the telescopic shaft along its axial direction. The limiting block is slidably disposed within the limiting groove. By providing the limiting block and the limiting groove to cooperate, the drive shaft can easily drive the telescopic shaft to rotate.

[0027] In one embodiment, a lifting assembly is further included, the lifting assembly comprising:

[0028] The telescopic column is provided in two sets. The two sets of telescopic columns can be slidably installed on the two sets of columns along the height direction of the base, and the top of the two sets of telescopic columns are respectively connected to the two sets of mounting seats.

[0029] A second drive assembly is disposed on the base and connected to the two sets of telescopic columns. The second drive assembly can drive the two sets of telescopic columns to slide.

[0030] In one embodiment, the second drive assembly includes adjusting screws, rotating shafts, and a dual-output motor. The dual-output motor is mounted on the base, and both output ends of the motor are connected to rotating shafts via couplings. Adjusting screws are rotatably mounted within both sets of columns. One end of each adjusting screw is threadedly connected to one of the two sets of telescopic columns, and the other end of each adjusting screw is equipped with a third bevel gear. A fourth bevel gear is mounted on each of the two rotating shafts, with the third and fourth bevel gears meshing at the same end. The dual-output motor drives the two rotating shafts to rotate, which in turn drives the two sets of fourth bevel gears to rotate. The meshing of the fourth and third bevel gears with the fourth bevel gears drives the adjusting screws to rotate in the same direction. This rotation, in turn, engages with the threaded connections of the telescopic columns, causing them to slide. This sliding movement of the telescopic columns moves the two mounting seats up and down, which in turn moves the mounting frame up and down, thus adjusting the exercise height of the device for different patients.

[0049] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0050] Please see Figure 1 , 3 4, 8, One embodiment of a resistance training device for patients with chronic kidney disease includes a base 10 and a training mechanism 30.

[0051] The base 10 has two sets of uprights 101 spaced apart, each set of uprights 101 having a mounting base 102, and mounting brackets 20 connected to the mounting bases 102. Specifically, it also includes a lifting assembly 80, which comprises telescopic columns 805 and a second drive assembly. Two sets of telescopic columns 805 are provided, slidably mounted on the two sets of uprights 101 along the height direction of the base 10, and their tops are respectively connected to the two sets of mounting bases 102. The second drive assembly is mounted on the base 10 and connected to the two sets of telescopic columns 805, and drives the two sets of telescopic columns 805 to slide.

[0052] The second drive assembly includes an adjusting screw 806, a rotating shaft 802, and a dual-output motor 801. The dual-output motor 801 is mounted on the base 10, and both output ends of the dual-output motor 801 are connected to the rotating shaft 802 via couplings. Adjusting screws 806 are rotatably mounted inside both sets of columns 101. One end of each set of adjusting screws 806 is threadedly connected to two sets of telescopic columns 805, and the other end of each set of adjusting screws 806 is equipped with a third bevel gear 804. A fourth bevel gear 803 is mounted on each set of rotating shafts 802, and the third bevel gear 804 and the fourth bevel gear 803 at the same end mesh.

[0053] In the above embodiment, by starting the dual-output motor 801, two sets of rotating shafts 802 are driven to rotate. The rotation of the two sets of rotating shafts 802 drives two sets of fourth bevel gears 803 to rotate. The rotation of the two sets of fourth bevel gears 803 meshes with the two sets of third bevel gears 804, which drives the two sets of adjusting screws 806 to rotate in the same direction. The rotation of the two sets of adjusting screws 806 in the same direction engages with the two sets of telescopic columns 805 through threaded engagement, which drives the two sets of telescopic columns 805 to slide. The sliding of the two sets of telescopic columns 805 drives the two sets of mounting seats 102 to move up and down. The up and down movement of the two sets of mounting seats 102 drives the mounting frame 20 to move up and down. The up and down movement of the mounting frame 20 adjusts the exercise height of the device, making it convenient for different patients to use.

[0054] The exercise mechanism 30 includes a lifting rod 301, a mounting plate 302, first springs 303, and a first adjustment mechanism. The lifting rod 301 is slidably mounted on the mounting frame 20 at both ends along the height direction of the base 10. Specifically, in this embodiment, each end of the lifting rod 301 is provided with a slider 3012, and the mounting frame 20 has two sets of sliding grooves 206 corresponding to the two sets of sliders 3012, allowing the two sets of sliders 3012 to slidably mount within the two sets of sliding grooves 206 along the height direction of the base 10. The mounting plate 302 is mounted on the lifting rod 301. Multiple sets of first springs 303 are detachably mounted at intervals at both ends of the mounting plate 302, and the mounting frame 20 has multiple sets of through holes 201 corresponding to the multiple sets of first springs 303, allowing the multiple sets of first springs 303 to pass through the multiple sets of through holes 201. Specifically, in this embodiment, the multiple sets of first springs 303 are threadedly connected to the mounting plate 302, facilitating the installation and removal of the first springs 303. The first adjustment mechanism includes two sets of baffles 304 and a first drive assembly. The two sets of baffles 304 are slidably mounted on the mounting frame 20 along the length of the base 10 and can sequentially block or open multiple sets of through holes 201. The first drive assembly is mounted on the mounting frame 20 and connected to the two sets of baffles 304. The first drive assembly is used to drive the two sets of baffles 304 to slide.

[0055] Based on the above embodiments, the first driving assembly further includes a bidirectional screw 305, two sets of synchronous pulleys 306, and a synchronous belt 307. The mounting frame 20 has a guide groove 202 with multiple through holes 201. Two sets of baffles 304 are slidably disposed within the guide groove 202. The bidirectional screw 305 is rotatably disposed within the guide groove 202, and its two ends are threadedly connected to the two sets of baffles 304 respectively. One set of synchronous pulleys 306 is coaxially disposed on the bidirectional screw 305, and the other set of synchronous pulleys 306 is rotatably disposed on the mounting frame 20 and close to the mounting base 102. The two sets of synchronous pulleys 306 are connected by the synchronous belt 307. Specifically, in this embodiment, a first rocker wheel is coaxially connected to the synchronous pulley 306 close to the mounting base 102. The first rocker wheel facilitates the rotation of the synchronous pulley 306.

[0056] In the above embodiment, weightlifting exercises can be performed by gripping the lifting bar 301 and sliding it up and down with the upper limbs. When it is necessary to adjust the weight, the synchronous pulley 306 near the mounting base 102 is rotated. The rotation of the synchronous pulley 306 drives another set of synchronous pulleys 306 to rotate via the synchronous belt 307, which in turn drives the bidirectional screw 305 to rotate. The rotation of the bidirectional screw 305 engages with the threads of the two sets of baffles 304, causing the two sets of baffles 304 to slide away from each other. The two sets of baffles 304 sliding away from each other can block the through holes 201. When a suitable number of through holes 201 are blocked, the rotation of the synchronous pulley 306 is stopped. At this time, the bidirectional screw 305 stops rotating and engages with the threads of the two sets of baffles 304. After fixing and adjusting, when the lifting rod 301 moves upward, it drives multiple sets of first springs 303 to move upward via the mounting plate 302. The upward movement of the multiple sets of first springs 303 causes the first spring 303 corresponding to the blocked through hole 201 to abut against the baffle 304. At this time, the force required for the lifting rod 301 to move upward is increased, thereby increasing the lifting weight of the device. By rotating the bidirectional screw 305 to drive the two sets of baffles 304 to slide, the number of blocked through holes 201 can be changed, causing the corresponding number of first springs 303 to abut against the two sets of baffles 304. This makes it easy to change the lifting weight according to the patient's needs. Changing the lifting weight is convenient and does not require disassembling the first springs 303, thus improving the safety of the device.

[0057] Please see Figures 3 to 5 In one embodiment, the exercise mechanism 30 further includes a fall protection component 40, which includes a locking block 403, a second spring 404, and a pressing component. The lifting rod 301 has mounting grooves 3011 at both ends, and a locking block 403 is slidably disposed within each of the two sets of mounting grooves 3011. The mounting bracket 20 has locking slots 203 at both ends, with multiple sets of locking slots 203 spaced apart along the height direction of the base 10. One end of each set of locking blocks 403 can pass through the locking slot 203. The other end of each set of locking blocks 403 is connected to the side wall of the mounting groove 3011 via the second spring 404. The pressing component is disposed on the lifting rod 301 and connected to the two sets of locking blocks 403. The pressing component is used to drive the two sets of locking blocks 403 to move closer together, so that the two sets of locking blocks 403 separate from the locking slots 203.

[0058] Specifically, the pressing assembly includes a pressure rod 402 and a third spring 401. Multiple sets of connecting shafts 4021 are spaced apart on the pressure rod 402. These connecting shafts 4021 can slide radially through the lifting rod 301 and are limited by a limiting knob 4022. Both ends of the pressure rod 402 are provided with abutment rods 4023, and both sets of locking blocks 403 are provided with inclined surfaces 4031. The bottom ends of the two sets of abutment rods 4023 contact the two sets of inclined surfaces 4031 respectively. A third spring 401 is sleeved on each of the multiple sets of connecting shafts 4021, with both ends of the third spring 401 abutting against the pressure rod 402 and the lifting rod 301 respectively.

[0059] In the above embodiment, when holding the lifting bar 301 for weightlifting exercises, pressure is applied to the pressure bar 402 with the fingers, causing the pressure bar 402 to move closer to the lifting bar 301. At this time, the third spring 401 is compressed and contracts, and the abutment bar 4023 moves to press the inclined surface 4031, causing the locking block 403 to move and separate from the locking groove 203. Simultaneously, the second spring 404 is compressed and contracts, and the locking block 403 separates from the locking groove 203, thus releasing the lock on the lifting bar 301. At this time, the upper limbs can be used to move the lifting bar 301 up and down for weightlifting exercises. When the hand slips off the lifting bar 301, the lifting bar 301 is subjected to gravity and the first spring 304. Under the reaction force of spring 3, the lifting rod 402 moves downward. At the same time, the pressure on the lifting rod 402 disappears. The reaction force of the third spring 401 causes the lifting rod 402 to move in the opposite direction and reset. The reverse movement of the lifting rod 402 causes the abutment rod 4023 to release the pressure on the inclined surface 4031. At this time, the reaction force of the second spring 404 drives the locking block 403 to move in the opposite direction. When the lifting rod 301 moves downward and the locking block 403 aligns with the locking groove 203, the locking block 403 passes through the locking groove 203 to fix the lifting rod 301, thereby preventing the lifting rod 301 from falling and injuring the user, and improving the safety of the device.

[0060] Please see Figures 3 to 5 In one embodiment, the exercise mechanism 30 further includes a second adjustment mechanism, which includes an adjustment component 50, a pressure plate 60, and a transmission component 70. The mounting frame 20 is connected to two sets of mounting seats 102 via the adjustment component 50. The adjustment component 50 can drive the mounting frame 20 to rotate so that both ends of the mounting frame 20 are perpendicular to the column 101. The pressure plate 60 is located between the lifting rod 301 and the mounting plate 302. Connecting sleeves 601 are provided at both ends of the pressure plate 60, and the two sets of connecting sleeves 601 are fitted onto the lifting rod 301. The transmission component 70 connects the column 101, the mounting frame 20, and the connecting sleeves 601. Rotation of the mounting frame 20 can drive the pressure plate 60 to rotate via the transmission component 70, so that the lifting rod 301 is located between the pressure plate 60 and the mounting plate 302.

[0061] Specifically, the adjusting assembly 50 includes a worm gear 501 and a worm 502; the mounting bracket 20 has a first fixing hole 204 at one end and a first fixing shaft 205 at the other end. One set of mounting seats 102 has a second fixing shaft 1021, and another set of mounting seats 102 has a second fixing hole 1022. The first fixing hole 204 is fitted onto the second fixing shaft 1021, and the first fixing shaft 205 passes through the second fixing hole 1022. The worm gear 501 is coaxially mounted on the first fixing shaft 205, and the worm 502 is rotatably mounted on the mounting seat 102 and meshes with the worm gear 501. In this embodiment, a second handwheel is provided at one end of the worm 502. The second handwheel facilitates the rotation of the worm 502, making rotation convenient and effortless.

[0062] The transmission assembly 70 includes a transmission shaft 703, a telescopic shaft 704, a first gear 701, a second gear 706, a first bevel gear 702, and a second bevel gear 705. The transmission shaft 703 is rotatably mounted on the mounting bracket 20. The telescopic shaft 704 is rotatably mounted on the lifting rod 301, and one end of the telescopic shaft 704 is slidably inserted into the transmission shaft 703. The first gear 701 is rotatably mounted on the mounting bracket 20. The second gear 706 is mounted on the second fixed shaft 1021 and meshes with the first gear 701. The number of teeth of the second gear 706 is twice that of the first gear 701. The first gear 701 and the transmission shaft 703 are both coaxially mounted with first bevel gears 702, and the two sets of first bevel gears 702 mesh. The telescopic shaft 704 and one of the connecting sleeves 601 are both coaxially mounted with second bevel gears 705, and the two sets of second bevel gears 705 mesh.

[0063] A limiting block 7031 is provided on the drive shaft 703 along its axial direction, and a limiting groove 7041 is provided on the periphery of the telescopic shaft 704 along its axial direction. The limiting block 7031 is slidably disposed in the limiting groove 7041.

[0064] In the above embodiment, by rotating the worm 502, the worm 502 meshes with the worm wheel 501, driving the worm wheel 501 to rotate. The rotation of the worm wheel 501 drives the first fixed shaft 205 to rotate, which in turn drives the mounting bracket 20 to rotate. When the mounting bracket 20 rotates until both ends of the mounting bracket 20 are perpendicular to the column 101, the rotation of the worm 502 is stopped. The worm 502 stops rotating and engages with the worm wheel 501 to fix the worm wheel 501, thereby fixing the mounting bracket 20. Simultaneously, when the mounting bracket 20 rotates, it drives the first gear 701 to rotate around the second gear 706. Since the first gear 701 and the second gear 706 mesh, at this time... The rotation of the first gear 701 drives the transmission shaft 703 to rotate via the meshing of two sets of first bevel gears 702. The rotation of the transmission shaft 703, through the engagement of the limiting block 7031 and the limiting groove 7041, drives the telescopic shaft 704 to rotate. The rotation of the telescopic shaft 704, through the meshing of two sets of second bevel gears 705, drives the connecting sleeve 601 to rotate. The rotation of the connecting sleeve 601 drives the pressure plate 60 to rotate, thereby rotating the pressure plate 60 out and positioning the lifting rod 301 between the pressure plate 60 and the mounting plate 302. With the pressure plate 60 rotated out, the patient can support their upper limbs on it to perform wall push-ups. By changing the resistance training method, it is convenient for different patients to use, improving the practicality of the device. Conversely, by rotating the worm gear 502 in the opposite direction to reset the mounting frame 20, the pressure plate 60 can be reset, allowing for weightlifting exercises. Switching between different training methods is convenient and quick.

[0065] Based on the above embodiments, a further anti-slip pad 602 is provided on the surface of the pressure plate 60 facing away from the lifting rod 301. By providing the anti-slip pad 602, when the patient performs wall push-ups, the patient's hands come into contact with the anti-slip pad 602, thereby increasing the friction between the patient's hands and the pressure plate 60 and preventing the patient from slipping during wall push-ups.

[0066] The specific implementation method of the above-mentioned resistance training device for patients with chronic kidney disease is as follows:

[0067] During weightlifting exercises, by holding the lifting bar 301 and applying pressure to the pressure bar 402 with your fingers, the pressure bar 402 moves closer to the lifting bar 301. At this time, the third spring 401 is compressed and contracts, and the abutment bar 4023 moves and presses the inclined surface 4031, causing the locking block 403 to move and separate from the locking groove 203. At the same time, the second spring 404 is compressed and contracts, and the locking block 403 separates from the locking groove 203, thus releasing the lock on the lifting bar 301. At this time, you can apply force with your upper limbs to move the lifting bar 301 up and down to perform weightlifting exercises.

[0068] When it is necessary to change the weight for weightlifting exercises, the synchronous pulley 306 near the mounting base 102 is rotated. This rotation drives another set of synchronous pulleys 306 via the synchronous belt 307, which in turn drives the bidirectional screw 305. The bidirectional screw 305, through its threaded engagement with the two sets of baffles 304, drives the two sets of baffles 304 to slide away from each other. This relative movement of the two sets of baffles 304 blocks the through holes 201. When a suitable number of through holes 201 are blocked, the rotation of the synchronous pulley 306 is stopped. At this point, the bidirectional screw 305 stops rotating and, through its threaded engagement with the two sets of baffles 304, fixes the two sets of baffles 304. After adjustment, when the lifting rod 301 moves upward... When the lifting rod 301 moves upward via the mounting plate 302, multiple sets of first springs 303 move upward, causing the first spring 303 corresponding to the blocked through hole 201 to abut against the baffle 304. This increases the force required for the lifting rod 301 to move upward, thereby increasing the lifting weight of the device. By rotating the bidirectional screw 305 to drive the two sets of baffles 304 to slide, the number of blocked through holes 201 can be changed, causing the corresponding number of first springs 303 to abut against the two sets of baffles 304. This allows the lifting weight to be easily changed according to the patient's needs. Changing the lifting weight is convenient and does not require disassembling the first springs 303, improving the safety of the device.

[0069] Meanwhile, during weightlifting exercises, when the hand slips off the lifting bar 301, the lifting bar 301 moves downward under the force of gravity and the reaction force of the first spring 303. At the same time, the pressure on the pressure bar 402 disappears, and the reaction force of the third spring 401 causes the pressure bar 402 to move in the opposite direction and reset. The reverse movement of the pressure bar 402 causes the abutment bar 4023 to release the pressure on the inclined plane 4031. At this time, the reaction force of the second spring 404 drives the locking block 403 to move in the opposite direction. When the lifting bar 301 moves downward and the locking block 403 aligns with the locking groove 203, the locking block 403 passes through the locking groove 203 to fix the lifting bar 301, thereby preventing the lifting bar 301 from falling and injuring the user, and improving the safety of the device.

[0070] When switching exercise modes is required, rotating the worm gear 502 engages with the worm wheel 501, driving the worm wheel 501 to rotate. The rotation of the worm wheel 501 then drives the first fixed shaft 205 to rotate, which in turn drives the mounting frame 20 to rotate. When the mounting frame 20 rotates until both ends are perpendicular to the column 101, rotating the worm gear 502 stops. The worm gear 502 then engages with the worm wheel 501 to fix the worm wheel 501, thus fixing the mounting frame 20. Simultaneously, the rotation of the mounting frame 20 drives the first gear 701 to rotate around the second gear 706. Since the first gear 701 and the second gear 706 are engaged, this… When the device is in operation, the first gear 701 rotates, which drives the transmission shaft 703 to rotate through the meshing of two sets of first bevel gears 702. The rotation of the transmission shaft 703 drives the telescopic shaft 704 to rotate through the engagement of the limiting block 7031 and the limiting groove 7041. The rotation of the telescopic shaft 704 drives the connecting sleeve 601 to rotate through the meshing of two sets of second bevel gears 705. The rotation of the connecting sleeve 601 drives the pressure plate 60 to rotate, thereby rotating the pressure plate 60 out and positioning the lifting rod 301 between the pressure plate 60 and the mounting plate 302. With the pressure plate 60 rotated out, the patient can support their upper limbs on the pressure plate 60 to perform wall push-ups. By changing the resistance training mode, it is convenient for different patients to use, improving the practicality of the device. Conversely, by rotating the worm gear 502 in the opposite direction to reset the mounting frame 20, the pressure plate 60 can be reset, allowing for weightlifting exercises. Switching between different training modes is convenient and quick.
