[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] like Figure 1-Figure 6 A wrist joint rehabilitation training device shown in the figure includes a base 1, which is hollow.

A telescopic mechanism 4 is installed in the base 1, and a connecting mechanism 5 is connected between the telescopic mechanism 4 and the rotating mechanism 3, and the telescopic mechanism 4 provides power for the rotating mechanism 3.

[0025] A further improvement of the technical solution is that the arm fixing device 2 includes a mounting frame, and a plurality of clamping belts 22 are installed on the mounting frame. The clamping belts 22 are used to fix the forearm. The clamping belts 22 are prior art, and the two sides are fixed by Velcro, so the size is adjustable to adapt to different sizes of forearms. The fixing plate 21 is installed on the base 1.

[0026] A further improvement of the technical solution is that the rotating mechanism 3 includes two fixed frames 31, and a sleeve 32 is installed on the fixed frame 31, a sliding rod 33 is slidably connected in the sleeve 32, and a disc 34 is installed at one end of the sliding rod 33, a rotating disk 35 is rotatably connected to the disc 34, and a U-shaped support frame 36 is provided on the rotating disk 35, one end of the U-shaped support frame 36 is installed on the rotating disk 35, and the other end of the U-shaped support frame 36 is provided with a hand-held portion 37, and the hand-held portion 37 is used for handholding.

[0027] The further improvement of the technical solution is that the hand-held part 37 includes a round rod 371, and an elastic sleeve 372 is sleeved on the round rod 371, a U-shaped guard plate 373 is installed on the round rod 371, and fixed blocks 374 are installed at both ends of the round rod 371. A slide groove 375 is opened on the fixed block 374, and the other end of the U-shaped support frame 36 passes through the slide groove 375. The U-shaped support frame 36 and the slide groove 375 are slidably connected. A threaded rod 376 is provided on one side of the fixed block 374, and one end of the threaded rod 376 extends to the inside of the slide groove 375. The threaded rod 376 and the fixed block 374 are threadedly connected. The threaded rod 376 cooperates with the fixed block 374 to adjust the position of the hand-held part 37 on the U-shaped support frame 36.

[0028] By limiting the fixing block 374 through the threaded rod 376, the position of the fixing block 374 on the U-shaped support frame 36 can be adjusted, thereby adjusting the position of the handheld part 37 on the U-shaped support frame 36 to accommodate patients with different arm lengths.

[0029] A further improvement of the technical solution is that the telescopic mechanism 4 includes a motor 41, a rotating rod 42 is installed at one end of the output shaft of the motor 41, and the end of the rotating rod 42 away from the motor 41 is rotatably connected to the inner wall of the base 1, an external thread is provided on the outer periphery of the rotating rod 42, a moving block 43 is sleeved on the rotating rod 42, and the moving block 43 is threadedly connected to the rotating rod 42 at the penetration point, and the motor 41 is a servo motor 41, which can rotate forward and reverse.

[0030] A further improvement of the technical solution is that the telescopic mechanism 4 can be replaced by other existing driving structures that can drive the connecting rod 51 to move horizontally back and forth.

[0031] A further improvement of the technical solution is that the connecting mechanism 5 includes a connecting rod 51, and the connecting rod 51 is installed on the moving block 43. Strip grooves 52 are provided on both sides of the base 1. The strip grooves 52 are connected to the inner cavity of the base 1. Both ends of the connecting rod 51 pass through and extend to the outside of the strip grooves 52. Both ends of the connecting rod 51 are installed with a first fixed plate 5321. The first fixed plate 5321 is rotatably connected to the second fixed plate 5421. The second fixed plate 5421 is rotatably connected to the third fixed plate 5521. The third fixed plate 5521 is fixedly connected to the rotating disk 35.

[0032] The connecting rod 51 is pushed to perform horizontal reciprocating motion by the telescopic mechanism 4, thereby driving the rotating disk 35 to rotate a certain angle and then return to its original position, thereby forming a deflection training of the wrist. In addition, the arm fixing device 2 is provided, and the wearable device can be used by wearing the clamping belt 22. The structural design is simple and convenient to use.

[0033] Through the structural design of the sleeve 32 and the slide rod 33, the sleeve 32 limits the slide rod 33 connected to the rotating disk 35, so as to realize the positioning of the rotating disk 35 during the movement, so that the rotation of the rotating disk 35 is more stable.

[0034] During the working process of this embodiment:

[0035] The user's forearm is placed in the clamping belt 22, the user holds the elastic sleeve 372, and then the clamping belt 22 fixes the user's forearm;

[0036] Next, the motor 41 can be started by remote control, and the motor 41 drives the rotating rod 42 to rotate forward and reverse, thereby driving the moving block 43 to reciprocate horizontally, and then drives the connecting rod 51 and the first fixed plate 5321 to reciprocate horizontally. The horizontal reciprocating motion of the first fixed plate 5321 drives the second fixed plate 5421 to rotate on the first fixed plate 5321, and the second fixed plate 5421 also moves with the first fixed plate 5321, and the second fixed plate 5421 drives the third fixed plate 5521 to reciprocate and move with the second fixed plate 5421.

[0037] The reciprocating rotation of the third fixing plate 5521 drives the rotating disk 35 to reciprocate by a certain angle. The offset angle of the rotating disk 35 is related to the moving distance of the moving block 43, thereby driving the U-shaped support frame 36 and the hand-held part 37 to reciprocate, thereby realizing the reciprocating rotation of the wrist joint of the user's wrist on the hand-held part 37.

[0038] When it is necessary to adjust the distance of the hand-held part 37 on the U-shaped support frame 36, the threaded rod 376 can be rotated, and the threaded rod 376 leaves the U-shaped support frame 36 to release the limit on the fixed block 374, so that the fixed block 374 slides on the U-shaped support frame 36. After the two threaded rods 376 release the limit on the fixed block 374, the distance of the fixed block 374 on the U-shaped support frame 36 is adjusted, thereby adjusting the position of the round rod 371 and the elastic sleeve 372 connected to the fixed block 374. After the adjustment is completed, the threaded rod 376 is rotated again, and the threaded rod 376 is close to the U-shaped support frame 36, thereby fixing the fixed block 374 connected to the threaded rod 376.
