Description

Technical Field

[0002] Leg rehabilitation therapy assistive devices are an important type of medical tool designed to help patients with leg injuries or limited leg function regain the ability to walk and live. These devices include various orthotics, walkers, rehabilitation machinery and life-assistive devices. For patients who need rehabilitation after injury or surgery, leg rehabilitation therapy assistive devices provide support and stability to help them gradually restore walking and leg function. These devices can be adjusted according to individual needs to ensure the best treatment effect. At the same time, they help reduce additional burden and reduce the risk of secondary injuries. Leg rehabilitation therapy assistive devices are widely used in rehabilitation centers, hospitals and home environments. Through customized treatment plans and the guidance of professional medical staff, patients can gradually achieve independent walking and improve their quality of life. These devices not only provide important support for rehabilitation, but also provide more autonomy and freedom for those with limited leg function, helping them to reintegrate into social life. During use, the patient's rehabilitation needs vary depending on their injury conditions during the lower limb rehabilitation process.

[0023] Furthermore, the anti-skid foot pad 4 penetrates the outer surface of the training device housing 2, and the number of the anti-skid foot pad 4 is two.

[0024] Furthermore, the sit-stand switching mechanism 6 includes an articulated base 601, a seat base 602, a seat cushion 603, a synchronization rod 604, a connecting rod 605, an articulated platform 606, an articulated rod 607, an articulated sleeve 608 and a support rod 609. One end of the extension base 5 is fixedly connected to the articulated base 601, the top hinge of the articulated base 601 is connected to the seat base 602, the top surface of the seat base 602 is fixedly connected to the seat cushion 603, the outer surface of the seat base 602 is fixedly connected to the synchronization rod 604, the outer surface of the trainer base 1 is fixedly connected to the connecting rod 605, and the connecting rod 606 is fixedly connected to the outer surface of the trainer base 1. One end of the connecting rod 605 is fixedly connected to an articulated platform 606, the top surface of the articulated platform 606 is hingedly connected to an articulated rod 607, one end of the articulated rod 607 is hingedly connected to an articulated sleeve 608, and the inner surface of the articulated sleeve 608 is fixedly connected to a support rod 609. Through the arrangement of the articulated base 601, the seat base 602, the seat cushion 603, the synchronization rod 604, the connecting rod 605, the articulated platform 606, the articulated rod 607, the articulated sleeve 608 and the support rod 609, during use, the articulated base 601 is used to articulate the seat base 602 so that it can rotate and limit the rotation. The rotation angle is limited to within sixty degrees, and the current angle can be locked. The seat cushion 603 is installed on the top of the seat base 602 to contact the user's buttocks or legs to increase the comfort of use. The articulated platform 606 is connected to the training device base 1 through a connecting rod 605. Each articulated platform 606 is hinged with a connecting rod 605. The top of the connecting rod 605 is connected to the support rod 609 through an articulated sleeve 608 to form a parallel screw structure. The articulated platform 606 is the base and the support rod 609 is the connecting rod. Both connecting rods 605 are rockers. When the seat base 602 During rotation, since the synchronization rod 604 passes through the connecting rod 605, the connecting rod 605 will rotate together, and the position of the handrail 609 will drop. However, since it is a parallel four-bar structure, it is always parallel to the hinged platform 606. In this way, when the seat base 602 rotates downward, it is stuck by the hinged base 601, and the handrail 609 is fixed at the bottom position as a sitting armrest.

When the seat base 602 rotates, since the synchronization rods 604 penetrate the connecting rod 605, the connecting rod 605 will rotate together, so that the sitting state of the seat base 602 is synchronized with the sitting state of the handrail 609.

[0026] Furthermore, there are two articulated platforms 606 and they are symmetrically distributed on both sides of the training device base 1. There are two articulated rods 607 on each articulated platform 606. The support rod 609 runs through the articulated sleeve 608.

During use, when the trainer is used in a sitting position, the support column 702 is installed by engaging the base 701, and the rotating rod 703 can rotate and drive the friction shell 704 and the handle 705 to rotate. The user can raise or lower the handle 705 by himself to drive the friction shell 704 at the other end to move. Since the friction shell 704 is in contact with the rotating wheel 3, the greater the force of the friction shell 704 pressing down the rotating wheel 3, the greater the friction force, and the more difficult it is for the trainee to use the anti-slip foot pad 4 to rotate the rotating wheel 3. In this way, the trainee can control the friction force during rotation to increase or reduce the training intensity.

[0028] Furthermore, the support column 702 passes through the rotating rod 703, the friction shell 704 is slidably connected to the rotating wheel 3, the rotating rod 703 can rotate and drive the friction shell 704 and the handle 705 to rotate, the friction shell 704 is in contact with the rotating wheel 3, the greater the force with which the friction shell 704 presses down the rotating wheel 3, the greater the friction force, and the more difficult it is for the trainee to use the anti-slip foot pad 4 to rotate the rotating wheel 3, so that the trainee can control the friction force during rotation to increase or reduce the training intensity.

[0029] Furthermore, the friction shell 704 is made of hard rubber, and the handle 705 is made of PP plastic. The hard rubber has high friction and hardness, and the PP plastic is corrosion-resistant and can reduce the influence of the user's hand sweat.

[0030] Working principle: An auxiliary training stand for leg rehabilitation treatment. During use, the trainer base 1 provides stable support, and a rotating wheel 3 is rotatably connected in the trainer shell 2. The external non-slip foot pad 4 simulates the riding action to drive the rotating wheel 3 to rotate to achieve lower limb training. The articulated base 601 is used to articulate the seat base 602 so that it can rotate and limit the rotation angle. The seat pad 603 is installed on the top of the seat base 602 to contact the user's buttocks or legs. The articulated platform 606 is connected to the trainer base 1 through a connecting rod 605. Each articulated platform 606 is articulated with a connecting rod 605. The top of the connecting rod 605 is connected to the articulated sleeve 608 and the handrail 609. A parallel screw structure is formed. When the seat base 602 rotates, the synchronous rod 604 passes through the connecting rod 605, and the connecting rod 605 will rotate together. The position of the handrail 609 will drop, but it is always parallel to the hinged platform 606 because it is a parallel four-bar structure. The support column 702 is installed by engaging the base 701. The rotating rod 703 can rotate and drive the friction shell 704 and the handle 705 to rotate. The user can raise or lower the handle 705 by himself to drive the friction shell 704 at the other end to move. Since the friction shell 704 is in contact with the rotating wheel 3, the friction force and training intensity of the rotating wheel 3 can be increased or reduced, thereby completing an auxiliary training bracket for leg rehabilitation treatment.
