The proximal end of the humerus is spherical, and the glenoid fossa, where the scapula and humeral head meet, is a shallow glenoid fossa. The humeral head and glenoid fossa form the shoulder joint, which is surrounded by ligaments, tendons, and other tissues that stabilize the shoulder joint. Frozen shoulder, as the name suggests, is inflammation around the shoulder joint. Treatment for frozen shoulder often requires the use of rehabilitation devices.

[0023] 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 the embodiments.

[0024] Reference Figure 1-5 A device for treating shoulder periarthritis of the upper limbs rehabilitation comprises a base 1, the upper surface of the base 1 is fixedly connected to two columns 2, the inner walls of the two columns 2 are rotatably connected to a first screw rod 3, the outer surfaces of the two first screw rods 3 are threadedly connected to a movable plate 4, and the outer surface of the movable plate 4 is slidably connected to the inner wall of the column 2. In this embodiment, the sliding of the movable plate 4 is guided by the column 2, thereby improving the stability of the movable plate 4 during its movement, and a stretching component 5 is provided on the upper surface of the movable plate 4.

[0025] The stretching assembly 5 includes two vertical plates 501, the bottom surfaces of the two vertical plates 501 are fixedly connected to the upper surface of the movable plate 4, the outer surfaces of the two vertical plates 501 are provided with guide grooves 502, the inner walls of the two guide grooves 502 are slidably connected with moving blocks 503, and the side surfaces of the two moving blocks 503 close to each other are fixedly connected with connecting rods 504. In this embodiment, the movement of the moving blocks 503 is guided and limited by the guide grooves 502, thereby ensuring that the connecting rods 504 can be lifted and lowered stably, and the outer surface of the connecting rods 504 is provided with two sliding grooves 505.

[0026] The outer surface of the connecting rod 504 is fixedly connected to a fixed block 506, and both ends of the fixed block 506 are fixedly connected to a spring 507. The ends of the two springs 507 away from the outer surface of the fixed block 506 are fixedly connected to a slider 508. In this embodiment, the spring 507 is always in a pushing state, so that the slider 508 moves stably toward both ends, and the slider 508 is slidably connected to the outer surface of the connecting rod 504 and the inner wall of the slide groove 505. In this embodiment, the movement of the slider 508 is stably guided by the slide groove 505, so that the slider 508 can stably drive the toothed plug 512 to insert into the interior of the toothed groove 511.

[0027] The outer surface of the connecting rod 504 is rotatably connected to two winding rollers 509, and the outer surface of the winding rollers 509 is fixedly connected to the outer surface of the connecting rope 16. The inner walls of the two winding rollers 509 are installed with torsion springs 510, and one end of the torsion spring 510 is fixedly connected to the outer surface of the connecting rod 504. In this embodiment, the torsion spring 510 always drives the winding rollers 509 to reel in the connecting rope 16. If the movable plate 4 moves downward, the winding rollers 509 rotate in the opposite direction under the pull of the movable plate 4 and lengthen the connecting rope 16. The side of the two winding rollers 509 close to each other is provided with a toothed groove 5 11. The two sliders 508 are fixedly connected to a toothed plug 512 on the side away from each other, and the outer surface of the toothed plug 512 is inserted into the inner wall of the toothed groove 511. In this embodiment, after the toothed plug 512 is inserted into the inner wall of the toothed groove 511, the slider 508 is limited by the slide groove 505 and cannot rotate. Therefore, the insertion of the toothed plug 512 can limit the winding roller 509 and prevent it from rotating, thereby determining the length of the connecting rope 16. Two pull ropes 513 are fixedly connected to the outer surface of the connecting rod 504, and one end of the two pull ropes 513 is fixedly connected to the handle 514.

[0028] A dual-axis motor 6 is installed on the inner wall of the base 1, and both ends of the dual-axis motor 6 are fixedly connected to a second screw rod 7. The ends of the two second screw rods 7 that are away from each other are rotatably connected to the inner wall of the base 1, and the outer surfaces of the two second screw rods 7 are fixedly connected to the first bevel gear 8.

[0029] One end of each of the two first screw rods 3 is fixedly connected to a connecting shaft 9, and the outer surface of the connecting shaft 9 is rotatably connected to the inner wall of the base 1 and the column 2. One end of each of the two connecting shafts 9 is fixedly connected to a second bevel gear 10, and the second bevel gear 10 is meshed with the first bevel gear 8.

[0030] A bracket 11 is fixedly connected to the upper surface of the base 1 , and a sliding frame 12 is slidably connected to the inner wall of the bracket 11 . A plurality of counterweight plates 14 are placed on the surface of the base 1 , and the outer surface of the counterweight plates 14 is slidably connected to the inner wall of the sliding frame 12 .

[0031] Two sets of symmetrical sockets 13 are provided on the outer surface of the sliding frame 12. A pin 15 is inserted into the inner wall of each set of sockets 13, and the outer surface of the pin 15 is inserted into the inner wall of the counterweight plate 14. In this embodiment, the pin 15 is inserted into the sockets 13 at different heights, thereby limiting the counterweight plates 14 at different heights, so that different weights can be quickly changed. A connecting rope 16 is fixedly connected to the outer surface of the sliding frame 12, and the connecting rope 16 passes through the inner wall of the bracket 11 and extends to the outside.

[0032] Working principle: When using this embodiment, first start the dual-axis motor 6 to drive the second screw rods 7 at both ends to rotate. At this time, the meshing connection between the first bevel gear 8 and the connecting shaft 9 can drive the connecting shaft 9 and the first screw rod 3 to rotate. At this time, the rotation of the first screw rod 3 can drive the movable plate 4 to be raised and lowered. At this time, the movable plate 4 pulls the sliders 508 on both sides while adjusting to squeeze the spring 507. Then the movement of the slider 508 drives the toothed plug 512 to disengage from the inner wall of the toothed groove 511. Then, while the movable plate 4 is adjusting the lifting and lowering movement, the torsion spring 510 can always drive the winding roller 509 to rotate. Therefore, when the movable plate 4 moves upward, the winding roller 509 can drive the torsion spring 510 to rotate to reel in the connecting rope 16. If the movable plate 4 moves downward, At this time, the winding roller 509 rotates in the opposite direction under the pull of the movable plate 4 and lengthens the connecting rope 16. Afterwards, if the height of the movable plate 4 is determined, the pull on the slider 508 is released, and under the push of the spring 507, the slider 508 drives the toothed plug 512 to insert into the toothed groove 511 to limit the winding roller 509. Finally, if different weights need to be changed, it is only necessary to insert the pin 15 into the socket 13 at different heights to limit the counterweight plates 14 at different heights, so that different weights can be quickly changed. At this time, manually pull the handle 514 to drive the connecting rod 504 to move downward, and then the connecting rod 504 can drive the winding roller 509 to move, and under the connection of the connecting rope 16, it can drive the sliding frame 12 and the counterweight plate 14 to move, thereby performing rehabilitation training.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
