Round rods 9 are slidably installed in the two sliding holes 8. The ends of the two round rods 9 close to each other are fixedly installed with the same rectangular plate 10. Two rotating rods 11 are rotatably installed on the rectangular plate 10. One end of the two rotating rods 11 is fixedly installed with a disc 12. The ends of the two rotating rods 11 away from the two discs 12 are fixed. A limit block 1 is installed, and the two limit blocks 1 can prevent the two rotating rods 11 from falling off the rectangular plate 10. A handle 13 is provided on one side of the two discs 12.

The user holds the two handles with both hands, and the two discs 12 can be driven to rotate through the cooperation of the two handles and the two round rods. A clamping block 14 is fixedly installed on the inner wall of the side away from each other of the two frame blocks 5. The two clamping blocks 14 are triangular in shape. The two clamping blocks 14 are slidably installed in the corresponding two tooth grooves 7 respectively. A round block 15 is fixedly installed on the end of the two round rods 9 away from each other. Adjustment mechanisms are installed on the two circular blocks 15, and the two adjustment mechanisms include: four circular grooves 16, a fixing frame 17, a second threaded rod 18, a sliding block 19 and two snap-in blocks 20. The four circular grooves 16 are all opened on one side of the circular block 15, and the four circular grooves 16 are distributed in a ring array. The fixing frame 17 is fixedly installed on one side of the circular block 15, the second threaded rod 18 is rotatably installed on the fixing frame 17, a rotating wheel is fixedly installed on one end of the second threaded rod 18, and one end of the second threaded rod 18 is rotatably connected to the circular block 15, the sliding block 19 is threadedly installed on the second threaded rod 18, and the two snap-in blocks 20 are fixedly installed on one side of the sliding block 19, and the two snap-in blocks 20 are slidably installed in the corresponding two circular grooves 16.

[0023] In order to limit the movement tendency of the two frame blocks 5, increase the movement range of the two frame blocks 5, and increase the stability of the two frame blocks 5, two transverse rods are fixedly installed on the side of the two frame blocks 5 close to each other, and the four transverse rods are slidably connected to the two fixed blocks 2 respectively, and the ends of the four transverse rods away from the two frame blocks 5 are fixedly installed with limit blocks 2.

[0025] In order to reduce the wear of the eight circular grooves 16 , a protective pad is fixedly installed on the inner wall of one side of the eight circular grooves 16 , and the corresponding four protective pads are in contact with the four snap-in blocks 20 respectively.

[0026] In order to ensure a stable connection between the two threaded rods 18 and the two circular blocks 15, the ends of the two threaded rods 18 that are close to each other are supported, and the two circular blocks 15 are provided with mounting grooves on the sides that are away from each other. Bearings are fixedly installed on the inner walls of the two mounting grooves, and the two bearings are fixedly sleeved on the two threaded rods 18 respectively.

[0027] The working principle of the limb training device for the elderly provided by the utility model is as follows:

[0028] When the elderly need to use the limb trainer to exercise their shoulder joints and arms, if the height of the two discs 12 is not suitable, the two discs 12 can be adjusted according to actual needs. During operation, the rectangular plate 10 is supported to generate a supporting force on the rectangular plate 10, and then the threaded sleeve 3 is rotated. Under the influence of the thread, the two threaded rods 14 will move out of the threaded sleeve 3 at the same time, and the two threaded rods 14 will drive the two frame blocks 5, and the two frame blocks 5 will gradually move away from each other. The two frame blocks 5 will drive the two clamping blocks 14 to move at the same time, so that the two clamping blocks 14 are gradually moved out of the corresponding two tooth grooves 7. At this time, the fixing effect of the two frame blocks 5 on the mounting frame 6 has been released, and then the rotation of the threaded sleeve 3 is temporarily stopped according to one's own needs. To choose to move the rectangular plate 10 up or down, the rectangular plate 10 drives the mounting frame 6 through the two circular rods 9. After adjusting the rectangular plate 10 to an appropriate height, the height of the rectangular plate 10 is kept unchanged. At this time, the two clamping blocks 14 have been aligned with the other two tooth grooves 7. Then, the threaded sleeve 3 is rotated in the opposite direction, and the two threaded rods 14 move into the threaded sleeve 3 at the same time. The two frame blocks 5 gradually approach each other, driving the two clamping blocks 14 to be re-engaged in the corresponding two tooth grooves 7, thereby completing the fixation of the mounting frame 6. After adjustment, the two discs 12 on the rectangular plate 10 can be better suitable for the elderly who are currently using it, so that the elderly can move their bodies more freely and exercise more smoothly and comfortably during use, thereby enhancing their exercise experience.

[0029] Commonly, the two handles 13 are used to drive the two discs 12 to rotate, which can drive the user's upper limbs to swing up and down in a circle, thereby achieving exercise. If the up and down movement is more strenuous and uncomfortable, the placement direction of the rectangular plate 10 can be adjusted to change the direction of the user's force. During operation, the two threaded rods 18 are rotated in turn. During the rotation of the two threaded rods 18, the two sliding blocks 19 will be driven to slide, and the distance between the two sliding blocks 19 will be enlarged. The two sliding blocks 19 drive the four snap-in blocks 20 to move the four snap-in blocks 20 out of the corresponding four circular grooves 16. After the restriction of the four snap-in blocks 20 is lost, , the rectangular plate 10 can be rotated, and the rectangular plate 10 will rotate with the two circular rods 9 as the center of the circle, and the two discs 12 that were originally in an upright state are adjusted to a lying state, so that the two discs 12 are located above the rectangular plate 10, and after ensuring that the four snap-in blocks 20 are aligned with the other four circular grooves 16, the two threaded rods 18 are rotated in opposite directions in succession to move the four snap-in blocks 20 to the corresponding four circular grooves 16, and the rectangular plate 10 is fixed. At this time, the positions of the two discs 12 will be adjusted, and the force direction of the user has been changed, from the original up and down swing to the front and back swing, which is convenient for the user to use according to needs.

[0030] Compared with the related art, the limb training device for the elderly provided by the utility model has the following beneficial effects:

[0031] In the utility model, by manually rotating the threaded sleeve 3, the two frame blocks 5 and the two clamping blocks 14 can be driven to move simultaneously, and the fixation of the mounting frame 6 can be released, so that the height of the two discs 12 can be adjusted in time according to the needs of the user, so that the trainer can be suitable for elderly people with different appearances. In addition, the directions of the two discs 12 can be changed as needed, thereby changing the output direction of the trainer when it is used, thereby improving the flexibility of the equipment, making it suitable for different elderly people, relatively improving the user experience, and making it more practical.
