Description
Technical Field
[0001] The utility model relates to the technical field of leg rehabilitation equipment, in particular to a neurology lower limb rehabilitation device. Background Art
[0002] Patients with lower limb nerve diseases usually have difficulty walking, and may even suffer from lower limb paralysis. In order to prevent the patient's lower limb muscles from atrophying, caregivers are required to perform lower limb rehabilitation exercises on the patient, which increases the workload of caregivers. There are some existing lower limb rehabilitation devices that require the foot to push the pedal when exercising the legs. The pedal has a return function to exercise the lower limbs, but some patients are more serious and cannot apply thrust by themselves. They need to bend their legs in different ways to promote blood circulation in the legs and achieve the effect of training and rehabilitation. However, the existing pedals cannot provide automatic pulling force and return force to train the leg bending and promote blood circulation. Utility Model Content

DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0021] Reference Figure 1-6 A neurological lower limb rehabilitation device comprises a base 1, a seat 2, a foot push block 3 and a mechanical push assembly, wherein the seat 2 is arranged at the rear end of the upper surface of the base 1, two movable grooves 4 are arranged in the middle of the upper surface of the base 2, a foot push block 3 is arranged in the movable groove 4, and an inclined footrest surface 33 is arranged on the side of the foot push block 3 facing the seat 2, limiting slide rails 31 are arranged on both sides of the lower half of the foot push block 3, limiting slide grooves 311 for installing the limiting slide rails 31 are arranged on the inner walls of both sides of the movable groove 4, a spring cavity is arranged at one end of the movable groove 4, and the movable groove 4 is provided with a spring cavity. A sliding rod 5 is provided from the other end of the movable groove 4 to the movable cavity, and the sliding rod 5 movably passes through the foot push block 3. A return spring 51 is sleeved on the sliding rod 5 between the foot push block 3 and the spring cavity. The mechanical pushing assembly includes a pulling block 6, a screw rod 7 and a servo motor 71. The pulling block 6 is installed in the second limiting sliding groove on the two side walls of the movable groove 4 through a second sliding rail 61. The pulling block 6 is spirally sleeved on the screw rod 7, and one end of the screw rod 7 is connected to the rotating shaft of the servo motor 71. A connecting piece connected to the upper surface of the pulling block 6 is provided at the bottom of the foot push block 3.
[0022] With the support of a doctor or family member, the patient sits on the chair 2, places the sole of the foot on the inclined footrest surface 33, pushes hard (using the foot to push), pushes the foot push block 3 to bend the leg, and when it cannot be pushed, pulls the leg back, and the foot push block 3 automatically returns (pushed back by the return spring). However, such exercise requires a certain thrust of the leg. If the leg is weak, the leg is bent and returned to exercise the leg. At this time, the pulling block 6 needs to be pushed to the end. When the leg is not placed on the foot push block 3, the connecting piece is started to move down and connected with the pulling block 6. During exercise, the leg is placed on the inclined footrest surface 33, and the servo motor rotates back and forth, driving the pulling block 6 to move back and forth, pushing the leg to bend and return, and realizing the leg rehabilitation exercise of the weak patient.
[0023] The foot push block 3 is provided with two sets of straps 32 on both sides of the inclined footrest surface 33 , and a crescent-shaped heel baffle 331 is provided at the bottom of the inclined footrest surface 33 .
[0024] When the foot is placed on the foot and moved or separated from the foot push block 3, the foot surface is tied with a strap, and the heel is placed on the crescent-shaped heel baffle 331 to prevent it from sliding down.
[0025] The return spring 51 includes a first section outside the spring cavity and a second section inside the spring cavity. The return spring 61 is sleeved with a plurality of gaskets 52 on the slide bar 5 between the first section and the second section.
[0026] In order to increase the rebound force of the return spring when it moves a certain distance, the first segment is pulled outward to leave a gap between the first segment and the second segment. Several gaskets 52 are put on as needed to increase the elastic force of the return spring. The rebound force will increase every time the foot push block 3 moves a certain distance.
[0027] The gasket 52 comprises an upper semicircular gasket and a lower semicircular gasket, which are spliced and connected with bolts 521. When the gasket 52 is put on, the upper semicircular gasket and the lower semicircular gasket are spliced, and the bolts are inserted from the mounting holes and screwed into the other semicircular gasket for connection.
[0028] The connecting member includes a push-down cylinder 8 and a connecting rod. The push-down cylinder 8 is embedded in the four corners of the bottom of the foot push block 3. The cylinder shaft of the push-down cylinder 8 is connected to the connecting rod. Four rod insertion holes 62 are provided at the four corners of the upper surface of the pulling block 6.
[0029] The push-down cylinder 8 pushes the connecting rod downward to insert it into the rod insertion hole 62, thereby achieving connection. When connection is not required, the connecting rod can be pulled up.
[0030] The inclination angle of the inclined footrest surface on the foot push block 3 is 45°, which is more in line with the foot bending requirements.
[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
