[0029] Example

[0030] Please refer to Figure 1-Figure 5 This embodiment provides a limb exercise device, including a base 1 and two mounting cylinders 2 provided on the base 1. The two mounting cylinders 2 are parallel to each other and both ends of the mounting cylinders 2 are closed. A mounting chamber 3 is provided in the mounting cylinder 2. A slider 4 and a spring 5 are slidably provided in the mounting chamber 3. The top of the spring 5 abuts against the slider 4, and the bottom of the spring 5 abuts against the mounting cylinder 2.

[0031] The sidewall of the mounting cylinder 2 is provided with a guide hole 6 that communicates with the mounting chamber 3 along the sliding direction of the slider 4. The slider 4 is provided with a guide mounting plate 7. The end of the guide mounting plate 7, away from the slider 4, passes through the guide hole 6 and is provided with a footrest 8. In this embodiment, the two mounting cylinders 2 are connected together, and the two footrests 8 are located on the left and right sides, respectively, so that the user can easily place their feet on each footrest 8.

[0032] During actual use, the limb exercise device is placed on the ground, wherein the base 1 can be fixed to the ground by expansion screws or the like to improve the stability of the installation. The patient can sit on a hospital bed, a chair, or the like, with the patient's feet placed on the two foot pedals 8 respectively. Since the foot pedals 8 are mounted on the slider 4 through the guide mounting plate 7, a spring 5 is provided at the bottom of the slider 4. At this time, the user can alternately step on the foot pedals 8. When the left foot steps on the left foot pedal 8 and moves downward, the spring 5 on the left is compressed, and the resistance to the patient's left leg becomes greater. After stepping a certain distance, the left foot is retracted. At this time, the left foot pedal 8 is pushed upward and reset under the elastic force of the left spring 5. While retracting the left foot, the right foot steps on the right foot pedal 8 and moves downward. The above operation is repeated. The two legs alternately perform flexion and extension exercises, which promotes smooth blood circulation in the patient's lower limbs, reduces the labor intensity of the nursing staff, and is beneficial to the patient's recovery.

[0033] like Figure 1-Figure 3 As shown, in some embodiments of the present invention, anti-skid patterns are provided on the top of the footrest 8. By arranging the anti-skid patterns, the risk of the user's foot sliding on the footrest 8 can be reduced, making it convenient for the user to exercise.

[0034] like Figure 1 As shown, in some embodiments of the present invention, the bottom of the mounting cylinder 2 is rotatably mounted on the base 1 via a rotating shaft 10, and further includes an electric push rod 9, one end of which is hinged to the mounting cylinder 2, and the other end of which is hinged to the base 1. By providing the electric push rod 9, the present invention facilitates adjusting the tilt angle of the mounting cylinder 2 by extending and shortening the electric push rod 9, so that the angle of use can be adjusted to a comfortable level for the patient.

[0035] like Figure 1-Figure 5 As shown, in some embodiments of the present invention, an adjusting slide hole 11 is provided in the mounting cylinder 2, and the adjusting slide hole 11 is located below the mounting chamber 3 and is connected to the mounting chamber 3; an adjusting sliding block 12 is slidingly provided in the adjusting slide hole 11, and the bottom of the spring 5 is embedded in the adjusting slide hole 11 and abuts against the adjusting sliding block 12.

[0036] The present invention provides an adjustment slider 12, which can be slid within the adjustment hole 11 to adjust the height of the slider 12, thereby adjusting the length of the spring 5 before use. This facilitates adjusting the force applied by the patient to the foot pedal 8. For example, when used by a female patient, since they have less strength, the adjustment slider 12 can be adjusted downward, making the spring 5 longer and requiring less force to step down on the foot pedal 8. When used by a male patient, since they have greater strength, the adjustment slider 12 can be adjusted upward, making the spring 5 shorter and requiring more force to step down on the foot pedal 8.

[0037] like Figure 1-Figure 5As shown, in some embodiments of the present invention, an adjustment screw 13 is rotatably mounted at the bottom of the mounting barrel 2. The adjustment screw 13 passes through the adjustment slide 12 and is threadedly connected thereto. A drive plate 14 is disposed at the bottom of the adjustment screw 13. The drive plate 14 is located outside the mounting barrel 2 and is provided with a countersunk groove 15. The cross-sections of the adjustment slide 12 and the adjustment hole 11 are both polygonal. In this embodiment, the cross-sections of both the adjustment slide 12 and the adjustment hole 11 can be regular hexagons. This prevents the adjustment slide 12 from rotating within the adjustment hole 11 and only allows the adjustment slide 12 to slide axially within the adjustment hole 11.

[0038] The present invention facilitates adjustment of the position of the adjusting slide block 12 within the adjusting slide hole 11 by providing an adjusting screw 13. Since a driving plate 14 is provided at the bottom of the adjusting screw 13, and the driving plate 14 is provided with a countersunk groove 15, which can be a regular hexagonal groove, a regular hexagonal wrench can be inserted into the countersunk groove 15 during adjustment. By rotating the driving plate 14 with the wrench, the adjusting screw 13 rotates together. In this way, under the cooperation of the threaded connection, the rotating adjusting screw 13 can drive the adjusting slide block 12 to axially move and adjust the position within the adjusting slide hole 11, which is simple to operate.

[0039] like Figure 1-Figure 5 As shown, in some embodiments of the present invention, a limit rotating plate 16 is fixedly mounted on the outer wall of the adjusting screw 13. The limit rotating plate 16 is located in the adjusting slide hole 11 and below the adjusting slide block 12. By providing the limit rotating plate 16, the limit rotating plate 16 abuts against the inner wall of the mounting cylinder 2, thereby preventing the adjusting screw 13 from axially moving within the mounting cylinder 2.

[0040] like Figure 1-Figure 5 As shown, in some embodiments of the present invention, the drive plate 14 is fixedly sleeved with a ratchet 17, a pin 19 is fixedly provided at the bottom of the mounting cylinder 2, the pin 19 is rotatably provided with a pawl 18, and the pawl 18 engages with the ratchet 17; the pin 19 is sleeved with a torsion spring 20, one end of the torsion spring 20 is connected to the pin 19, and the other end of the torsion spring 20 is connected to the pawl 18.

[0041] The present invention provides a pawl 18 and a ratchet 17. After the position of the adjusting slide block 12 is adjusted by rotating the drive plate 14, the pawl 18 and the ratchet 17 are stably engaged together under the action of the torsion spring 20, thereby preventing the adjusting screw 13 from rotating during use. In other words, the adjusting slide block 12 is prevented from moving downward due to vibration and the downward thrust of the spring 5. In this way, the adjusting slide block 12 can be stably retained in the set position, improving stability during use. When the position of the adjusting slide block 12 needs to be adjusted downward, the relevant personnel only need to manually push the pawl 18 outward to disengage the pawl 18 from the ratchet 17.

[0042] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application.

[0043] Therefore, no matter from which point of view, the embodiments should be regarded as illustrative and non-restrictive, and the scope of this application is limited by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in this application. Any figure mark in the claims should not be regarded as limiting the claim involved. For those skilled in the art, various changes and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
