Description

Technical Field

[0001] This utility model relates to the field of leg rehabilitation equipment technology, specifically a leg rehabilitation exercise device. Background Technology

[0002] Leg rehabilitation is a systematic project that focuses on restoring normal leg function, effectively relieving pain and discomfort, strengthening leg muscles, and comprehensively improving mobility. It is typically suitable for people who have leg dysfunction due to injury, surgery, illness, or long-term lack of exercise.

[0003] In existing leg rehabilitation training, the maximum force that the leg can withstand is closely related to the patient's weight, age, and current rehabilitation status. Typically, training is conducted by having the leg contact a support surface. However, some patients, due to a lack of safety awareness, may subject their legs to excessive force during training and fail to disengage from the support surface in time, potentially causing secondary leg injury. To more effectively ensure patient safety, this application proposes a leg rehabilitation exercise device. Utility Model Content

[0004] The purpose of this invention is to provide a leg rehabilitation exercise device to solve the problem that patients cannot accurately judge the maximum force that their legs can withstand during existing leg rehabilitation training, which may lead to secondary leg injuries.

[0006] The push rod top block includes a top block, the bottom of which is fixedly connected to an electric push rod, and a roller is rotatably connected to the inner side of the top of the top block.

[0007] The pulley rocker arm component includes a rocker arm mounting shaft, on which a driving pulley is fixedly connected. Two rocker arms are symmetrically and fixedly connected at both ends of the rocker arm mounting shaft through the bottom support frame and around its axis. The two ends of the rocker arm mounting shaft are rotatably connected to the inner ends of the bottom support frame. The pulley mounting disc component includes a disc mounting shaft, on which a driven pulley is fixedly connected. The two ends of the disc mounting shaft are rotatably connected to the inner ends of the bottom support frame. Two mounting discs are symmetrically arranged at both ends of the driven pulley, and the two mounting discs are fixedly connected to the disc mounting shaft.

[0008] The pressure foot pedal component includes a foot pedal, one end of which is rotatably connected to a foot pedal mounting block. Two pressure sensors are symmetrically fixedly connected to the upper and lower ends of the foot pedal mounting block. The foot pedal mounting block is slidably connected to the inner side of the other end of the swing arm, and the two pressure sensors are fixedly connected to the inner side of the other end of the swing arm.

[0009] The upper support frame includes a seating section, one end of which is fixedly connected to a gripping section, and the bottom of the seating section is fixedly connected to the bottom support frame. One end of the transmission belt is meshed with the driving pulley, and the other end of the transmission belt is meshed with the driven pulley. The outer side of the counterweight wheel is provided with multiple waist-shaped grooves that rotate evenly around the axis, and the inner side of the counterweight wheel is rotatably connected to the disc mounting shaft.

[0010] The push rod adjustment rod includes a push rod mounting plate. Two adjustable electric push rods are symmetrically fixedly connected to both ends of one side of the push rod mounting plate. A locking rod is provided on one side of the two adjustable electric push rods that are close to each other. The other end of the adjustable electric push rod is fixedly connected to the mounting plate. One end of the locking rod is fixedly connected to the push rod mounting plate. A ball is rolled inside the other end of the locking rod.

It can select an appropriate number of counterweight wheels for rehabilitation training according to the patient's leg condition, thus avoiding secondary leg injury.

[0014] 2. This invention utilizes the contact between the patient's leg and the foot pedal to rotate the pulley swing arm component. The rotation is then driven by a transmission belt, which in turn rotates multiple counterweight wheels on the pulley mounting plate component for rehabilitation training. When the patient experiences leg discomfort and lifts their leg, a pressure sensor converts the pressure into an electrical signal, which is transmitted to the controller. The controller then controls the electric push rod of the top block to lift the top block, which in turn locks the counterweight wheels in place via a slot. This prevents the counterweight wheels from continuing to rotate due to rotational inertia, thus avoiding damage to the patient's leg and more effectively protecting patient safety.

[0023] Please see Figure 1-6This utility model provides a technical solution: a leg rehabilitation exercise device, including a bottom support frame 1, a wheeled swing arm component 2 is provided at one end of the top inner side of the bottom support frame 1, a wheeled mounting plate component 3 is provided at the other end of the top inner side of the bottom support frame 1, an upper support frame 4 is provided at the top of the bottom support frame 1, two pressure foot pedal components 5 are uniformly and symmetrically arranged around the axis at both ends of the wheeled swing arm component 2, a transmission belt 6 is provided on the outer side of the wheeled swing arm component 2, multiple counterweight wheels 7 are uniformly spaced on the inner side of both ends of the wheeled mounting plate component 3, two push rod adjusting rods 8 are uniformly and rotatably arranged around the axis on the outer side of both ends of the wheeled mounting plate component 3, a controller 9 is provided at one end of the top of the upper support frame 4, and multiple push rod top blocks 10 are respectively provided at the bottom of the multiple counterweight wheels 7;

[0024] The push rod top block 10 includes a top block 1001, a top block electric push rod 1002 is fixedly connected to the bottom of the top block 1001, and a roller 1003 is rotatably connected to the inner side of the top of the top block 1001. By setting the roller 1003, the friction between the top of the top block 1001 and the rotating counterweight wheel 7 can be reduced, avoiding damage to the counterweight wheel 7 and affecting the accuracy of the counterweight.

[0025] The pulley rocker arm component 2 includes a rocker arm mounting shaft 201, on which a driving pulley 202 is fixedly connected. Two rocker arms 203 are symmetrically and fixedly connected at both ends of the rocker arm mounting shaft 201 through the bottom support frame 1 around the axis. The two ends of the rocker arm mounting shaft 201 are rotatably connected to the inner ends of the bottom support frame 1. The pulley mounting disc component 3 includes a disc mounting shaft 301, on which a driven pulley 302 is fixedly connected. The two ends of the disc mounting shaft 301 are rotatably connected to the inner ends of the bottom support frame 1. Two mounting discs 303 are symmetrically arranged at both ends of the driven pulley 302. The two mounting discs 303 are fixedly connected to the disc mounting shaft 301.

[0026] The pressure foot pedal component 5 includes a foot pedal 501, with a foot pedal mounting block 502 rotatably connected to one end of the foot pedal 501. Two pressure sensors 503 are symmetrically fixedly connected to the upper and lower ends of the foot pedal mounting block 502. The foot pedal mounting block 502 is slidably connected to the inner side of the other end of the swing arm 203. The two pressure sensors 503 are fixedly connected to the inner side of the other end of the swing arm 203. By setting two pressure sensors 503, the force exertion of the patient's leg can be detected, and the device can be monitored to see if it is in motion. This facilitates the control of the rotation of the counterweight wheel 7 and prevents the counterweight wheel 7 from continuing to rotate due to inertia, which could cause injury to the patient's leg.

[0027] The upper support frame 4 includes a seating section 401, with a gripping section 402 fixedly connected to one end of the seating section 401. The bottom of the seating section 401 is fixedly connected to the bottom support frame 1. One end of the transmission belt 6 is meshed with the drive pulley 202, and the other end of the transmission belt 6 is meshed with the driven pulley 302. The outer side of the counterweight wheel 7 is evenly rotated around the axis with multiple waist-shaped slots 701. The inner side of the counterweight wheel 7 is rotatably connected to the disc mounting shaft 301. By setting multiple waist-shaped slots 701, it is convenient for the push rod adjusting rod 8 and the push rod top block 10 to cooperate with each other to adjust the number of counterweight wheels 7 and conduct more reasonable training.

[0028] The push rod adjusting rod 8 includes a push rod mounting plate 801. Two adjusting electric push rods 802 are symmetrically fixedly connected to both ends of one side of the push rod mounting plate 801. A locking rod 803 is provided on one side of the two adjusting electric push rods 802 close to each other. The other end of the adjusting electric push rod 802 is fixedly connected to the mounting plate 303. One end of the locking rod 803 is fixedly connected to the push rod mounting plate 801. A ball bearing 804 is rolled on the inner side of the other end of the locking rod 803. The other end of the locking rod 803 passes through the mounting plate 303 and is movably engaged with the counterweight wheel 7 through multiple waist-shaped slots 701. The locking rod 803 is slidably connected to the mounting plate 303. The top block 1001 is movably engaged with the counterweight wheel 7 through multiple waist-shaped slots 701. The bottom of the top block electric push rod 1002 is fixedly connected to the bottom support frame 1. By setting the ball bearing 804, the friction generated by the contact between the locking rod 803 and the counterweight wheel 7 can be reduced, avoiding wear of the counterweight wheel 7 and affecting the counterweight.

[0029] The controller 9 is fixedly connected to the top of the grip part 402, electrically connected to the pressure sensor 503, electrically connected to the adjusting electric push rod 802, and electrically connected to the top block electric push rod 1002. By setting the controller 9 on the top of the grip part 402, it is easier for the patient to control the device and carry out more reasonable rehabilitation training.

[0030] Working principle: The patient's buttocks contact the seating part 401, and both hands grasp the grip part 402. Through the controller 9, an appropriate number of counterweight wheels 7 are selected. The controller 9 sends electrical signals to multiple adjusting electric push rods 802, causing the multiple adjusting electric push rods 802 to drive the locking rod 803 to move, thereby engaging with the corresponding number of counterweight wheels 7 through the waist-shaped locking groove 701. The patient's two feet contact and apply pressure to the two foot pedals 501 respectively. The foot pedals 501 transmit the pressure to the pressure sensor 503, which converts the pressure into an electrical signal and transmits it to the controller 9. The controller 9 sends electrical signals to control multiple top block electric push rods 1002 to lower the corresponding top block 1001, releasing the corresponding counterweight wheel 7. This causes the patient to drive the two pressure wheel foot pedals 501 components, which in turn move through the two swing arms 203. The active pulley 202 on the movable swing arm mounting shaft 201 rotates, which drives the driven pulley 302 at the other end of the transmission belt 6 to rotate, thereby driving the multiple push rod adjusting rods 8 on the two mounting plates 303 to rotate. This causes the multiple push rod adjusting rods 8 to drive the counterweight wheel 7 to rotate for rehabilitation training. When the patient stops training, the foot pedal 501 loses pressure, which in turn causes the pressure sensor 503 to lose pressure. The pressure sensor 503 converts the pressure back into an electrical signal and transmits it to the controller 9. The controller 9 controls the multiple top block electric push rods 1002 to rise, which causes the roller 1003 on the top of the top block 1001 to fit tightly against the rotating counterweight wheel 7. When the waist-shaped groove 701 of the counterweight wheel 7 coincides with the top block 1001, the top block 1001 is engaged in the waist-shaped groove 701, thereby fixing the counterweight wheel 7 and stopping its rotation.

[0031] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
