Detailed Description

In order to more fully understand the technical content of the present invention, the technical solution of the present invention will be further described and illustrated with reference to the following specific embodiments, but not limited thereto.

It is to be understood that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity/action/object from another entity/action/object without necessarily requiring or implying any actual such relationship or order between such entities/actions/objects.

It should be further understood that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or system. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or system that comprises the element.

As shown in fig. 1, the utility model provides a leg exercise mechanism for lower limb rehabilitation training, which comprises a fixed frame 1, a power assembly connected with the fixed frame, and a rotating frame 4 hinged with the fixed frame 1; the rotating frame 4 is connected with a leg support 5; the power assembly comprises a motor 2 and a screw rod 22 connected with the output end of the motor 2; the device also comprises a push block 3, wherein one end of the push block 3 is connected with the screw rod 22, and the other end of the push block 3 is connected with the rotating frame 4; the motor 2 rotates in a forward direction or a reverse direction to rotate the leg support 5 clockwise or counterclockwise. The push block 3 is positioned at the inner side of the fixed frame 1. The outer end of the screw rod 22 is provided with a connecting block 23, and one side of the connecting block 23 is connected with one end of the push block 3.
