[0010] like Figs. 1 to 4 As shown, an upper limb rehabilitation training chair includes a seat 1 and an arm traction device. The arm traction device comprises a lever 2, a pedal 3, a guide wheel 4, a guide wheel frame 5 for fixing the guide wheel 4, a pull cable 6, and an arm support 7. The lever 2 is horizontally positioned and hinged to the bottom of the seat 1, with the hinge point located in the middle forward position. The pedal 3 is placed flat in front of the seat 1 and fixed to the front end of the lever 2. The guide wheel 4 and guide wheel frame 5 are located on the side of the seat 1. One end of the pull cable 6 is fixedly connected to the rear end of the lever 2, and the other end extends along the direction of the guide wheel 4. The armrest 7 is mounted from bottom to top, with guide wheels positioned along the edge of the seat from bottom to top. The guide wheel frame is used to fix the guide wheels and guide the pull cable to hang forward. The armrest 7 is an "L"-shaped bracket consisting of a forward-extending horizontal section and an upward-extending vertical section. The end of the vertical section of the armrest 7 is hinged to one side of the back of the seat 1, and the rear side of the vertical section abuts against the guide wheel frame 5, allowing the armrest to swing only forward. The front end of the horizontal section of the armrest 7 is connected to the end of the pull cable 6 hanging above. The lever 2 and pull cable 6 can be driven by the pedal 3 to swing the armrest 7. When sitting in the seat, the arm to be trained is placed on the armrest, and the pedal is pressed. The pull cable can then be used to continuously swing the armrest around the hinge axis at the end of the vertical section, thereby driving the arm to perform rehabilitation training activities around the shoulder.
[0011] The horizontal section of the arm support 7 is equipped with a forearm support plate 8, which is located on the top surface of the front section of the horizontal section of the arm support 7. The rear end of the forearm support plate 8 is hinged to the horizontal section of the arm support 7. After the pull cable 6 is changed from the front end of the horizontal section of the arm support 7 to the front end of the forearm support plate 8, the forearm support plate 8 can be swung by the pull cable 6. When the arm rests on the forearm support plate, the weight of the arm is transmitted to the arm support through the forearm support plate, causing the arm support to resist the guide wheel frame. When the pull cable moves the forearm support plate up and down, the arm support will not swing accordingly.
[0012] The horizontal section of the arm bracket 7 and the front end of the forearm support plate 8 are respectively provided with shaft holes, and the end of the pull cable 6 is provided with a connecting hook 9. By inserting the connecting hook 9 into the shaft hole, the arm bracket 7 or the forearm support plate 8 can be pulled to swing.
[0013] The pull wire 6 is connected with the front end of the forearm support plate 8, and the arm support 7 and the forearm support plate 8 are connected by the locking member 10. When the arm support and the forearm support plate are locked together by the locking member, the pull wire can swing the arm support, and after the locking is released, the pull wire can swing the forearm support plate. The locking member can be various existing devices such as a lock, a bandage or a bolt.
[0014] The locking member 10 is a "U"-shaped fork, and the arm support 7 and the forearm support plate 8 are respectively provided with insertion holes corresponding to the connection and cooperation of the "U"-shaped fork. When the two ends of the "U"-shaped fork are inserted into the insertion holes of the arm support and the forearm support plate, the two can be locked together.
[0015] The arm support 7 and the guide wheel frame 5 are respectively provided with insertion holes corresponding to the connection and cooperation of the "U"-shaped fork at the corresponding positions. When the "U"-shaped fork is inserted into the insertion holes between the arm support and the guide wheel frame, the pull wire will only pull the forearm support plate. At this time, the "U"-shaped fork has a place to put, and can also play the role of stabilizing the arm support.
[0016] The front end of the forearm support plate 8 is provided with a shaft hole, and the end of the pull wire 6 is provided with a connecting hook 9 connected with the shaft hole at the front end of the forearm support plate 8. After the locking member is set, only the forearm support plate can be connected.
[0017] The lever 2 has two, which are respectively hinged on both sides of the seat 1. The pedal is fixed at the front end of the two levers, and the pull wire is connected with one of the levers. The arm pulling device can be set on either side or both sides of the seat according to needs.
