[0054] The gait training device for rehabilitation further comprises a moving piece, a rotating piece, a lifting piece and a limiting piece.

[0055] The moving part is used to drive the base 1 to move, which includes a concave block 101, a fixed shaft 102 and a pulley 103. The concave block 101 is fixed on the bottom surface of the base 1, the fixed shaft 102 is fixed in the concave block 101, and the pulley 103 is rotatably sleeved on the fixed shaft 102. The moving part is symmetrically provided with four about the axis of the base 1. The base 1 is moved by the combination of the concave block 101, the fixed shaft 102 and the pulley 103. The four pulleys 103 are symmetrically distributed on both sides of the axis of the base 1. When the device needs to be moved, the user applies a horizontal pushing force or pulling force, the pulley 103 rotates on the fixed shaft 102, the friction is converted into rolling friction, so that the device can be more easily moved on the ground. The device can be moved to different use places such as a ward and a rehabilitation training room.

[0056] The rotating part is used to drive the rotating shaft 2 to rotate, which includes an L-shaped block 21, a first motor 22, a worm 23 and a worm gear 24. The L-shaped block 21 is fixedly sleeved on the base 1, the first motor 22 is fixed on the L-shaped block 21, the worm 23 is fixed on the output end of the first motor 22, and the worm gear 24 is fixed on the rotating shaft 2. The worm gear 24 is rotatably connected with the base 1, and the worm 23 is meshed with the worm gear 24. When the patient needs to turn around or change the training direction, the first motor 22 can be started by controlling the button 8, the first motor 22 drives the worm 23 to rotate, the worm 23 drives the worm gear 24 to rotate, so that the rotating shaft 2, the connecting rod 3 and the fixed rod 4 rotate as a whole, the direction of the seat 6 is changed, and the requirement of the patient to change the training direction during the rehabilitation training is met, for example, the direction of the seat 6 is adjusted when the training is changed from forward walking to lateral movement.

[0057] The lifting part is used to drive the screw 5 to slide up and down, which includes a sleeve frame 51, a second motor 52, a transmission shaft 53, a bevel gear 54, a support shaft 56, a bevel gear 55, a circular table 57 and a spring 58. The sleeve frame 51 is fixedly sleeved on the fixed rod 4, the second motor 52 is fixed on the side wall of the sleeve frame 51, the transmission shaft 53 is fixed on the output end of the second motor 52, the bevel gear 54 is fixedly sleeved on the transmission shaft 53, the support shaft 56 is fixed on the top surface of the sleeve frame 51, the bevel gear 55 is rotatably sleeved on the support shaft 56, the bevel gear 54 is meshed with the bevel gear 55, the circular table 57 is fixed on the bottom surface of the screw 5, and the spring 58 is sleeved on the screw 5. The two ends of the spring 58 are fixedly connected with the top surface of the circular table 57 and the bottom surface of the fixed rod 4. The spring 58 can play a buffering and auxiliary supporting role. When the seat 6 bears a large pressure, the spring 58 can absorb part of the impact force, protect the safety of the patient and improve the comfort of riding.

[0058] The bevel gear 55 is threadedly connected to the screw 5. The bevel gear 55 is hollow and has an external thread that mates with the screw 5. The patient can activate the second motor 52 via the control button 8 according to their height and training needs. The second motor 52 drives the transmission shaft 53 and the bevel gear 54 to rotate. The bevel gear 54 drives the bevel gear 55 to rotate. Due to the threaded connection between the bevel gear 55 and the screw 5, the screw 5 slides up and down within the fixed rod 4, thereby adjusting the height of the seat 6.

[0059] During training, the patient's body movements may generate significant impact, especially when sitting down or standing up. Spring 58 effectively cushions these impacts, preventing injury to the patient's spine, hips, and other areas. Meanwhile, the limiting mechanism of the handrail 7 not only facilitates height adjustment but also ensures stability during use through a dual locking mechanism of compression spring 73 and nut 75. Patients can confidently rely on the handrail 7 for support and balance adjustments, improving safety and comfort during training.

[0060] The limiting component is used to restrict the lifting and sliding of the handrail frame 7. The limiting component includes a socket 71, a T-shaped rod 72, a compression spring 73, a screw groove 74, and a nut 75. The socket 71 is opened on the handrail frame 7 and the sockets 71 are arranged linearly. The T-shaped rod 72 is slidably connected to the device base frame 1 and is inserted into the socket 71.

The screw groove 74 is opened on the T-shaped rod 72 and the nut 75 is threadedly connected to the T-shaped rod 72. The nut 75 and the T-shaped rod 72 are threadedly connected through the screw groove 74.

[0061] Control button 8 is electrically connected to the first motor 22 and the second motor 52. This allows patients or medical staff to easily operate and control the motors, enabling the switching and adjustment of various functions.

[0062] The functional principle of this utility model can be explained through the following operation methods:

[0063] When using this device, first adjust the height of the handrail 7, pull out the T-shaped plug 72 from the socket 71 currently connected to the handrail 7, then raise or lower the handrail 7 to a suitable height, release the T-shaped plug 72, and under the elastic force of the compression spring 73, the T-shaped plug 72 will insert into the corresponding socket 71, thereby quickly adjusting and fixing the height of the handrail 7. The nut 75 can further lock the position of the T-shaped plug 72 through the threaded engagement with the screw groove 74, preventing the T-shaped plug 72 from coming out of the socket 71 due to accidental collisions or other factors during use. This effectively ensures the stability of the height of the handrail 7 during training, allowing patients to safely and reliably rely on the handrail 7 for support and balance adjustment, improving safety and comfort during training.

[0064] Subsequently, according to the height of the body and the specific training needs to adjust, through the control button 8 to start the second motor 52 drive shaft 53 rotation, so that the fixed on the transmission shaft 53 bevel gear 54 with it rotates and engages with the bevel gear 55, so that the drive bevel gear 55 around the shaft 56 rotation, in turn drive screw 5 in the fixed rod 4 along the axial sliding, in turn realize the height of the bench 6 adjustment, in the process of bench 6 lifting, spring 58 play a buffer and auxiliary support role. When the bench 6 bears greater pressure (such as the patient sits down or gets up the moment), the spring 58 is compressed, can absorb part of the impact force, avoid the impact force is too large to cause harm to the patient's spine, hips and other body parts, at the same time after the motor stops working, spring 58 can assist in maintaining the position of the screw 5 stable, guarantee the bench 6 height relative constant, provide more comfortable and safe ride experience for the patient.

[0065] When the patient in the rehabilitation training process has the need to turn around or change the training direction, the control button 8 at the top of the handrail frame 7 can be operated to start the first motor 22, and the first motor 22 drives the worm 23 to rotate. Since the worm 23 is engaged with the worm gear 24 fixed on the rotating shaft 2 and connected with the device base 1, according to the worm gear 24 worm 23 transmission principle, the rotation of the worm 23 will drive the worm gear 24 to rotate around the axis of the rotating shaft 2, in turn drive the connecting rod 3 and the fixed rod 4 connected with the rotating shaft 2 to rotate synchronously, finally realize the steering function of the bench 6, for example, when carrying out different direction gait simulation training, the direction of the bench 6 can be adjusted flexibly to adapt to the training requirements, and then complete the gait training.

[0066] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art according to the technical solution and the utility model concept of the present application within the scope of the present application disclosed in the technical field, according to the technical solution and the utility model concept of the present application, equivalent replacement or change, should be covered in the protection scope of the present application.
