Description

Technical Field

[0001] The utility model belongs to the technical field of arm rehabilitation equipment, in particular to an arm rehabilitation exerciser. Background Art

[0002] Arm rehabilitation training is a rehabilitation method for arm injury, illness or impaired function after surgery. Its purpose is to help restore arm strength, flexibility, coordination, range of motion and fine motor control ability through a series of targeted exercises and activities. It is carried out under the guidance and supervision of a therapist to ensure the safety and effectiveness of the training.

[0003] After an arm injury or surgery, rehabilitation training is required in a timely manner to speed up the recovery of arm muscle function. Some rehabilitation equipment is independently set up and is not convenient to use next to the bed, which limits the patient's training scene and time. In addition, the weight adjustment of some equipment is not flexible enough to meet the needs of patients at different rehabilitation stages. For this reason, it is necessary to provide an arm rehabilitation exerciser that is set up in conjunction with the bed to facilitate special people who are inconvenient to get out of bed to conduct bed training, thereby expanding the patient training scene. Utility Model Content

[0010] Preferably, a wristband is fixedly connected to the rear end of the pull rope.

[0011] 1. The beneficial effect of the utility model is that the utility model counterweights the pulling force of the pull rope through the coordinated use of the support frame and the counterweight assembly, and guides the pull rope through the coordinated use of the support frame and the guide assembly. Then the user repeatedly pulls the pull rope, thereby achieving the purpose of convenient use, adjustable counterweight and stable pulling.

[0012] 2. The utility model limits the direction of the pull rope by using the steering wheel frame and the anti-slip pulley in coordination. At the same time, with the coordinated use of the fixed frame and the steering wheel frame, the anti-slip pulley can adjust itself according to the pulling direction of the pull rope, thereby preventing the pull rope from being separated from the surface of the anti-slip pulley and ensuring the stability of the pull rope during movement.

[0013] 3. The utility model uses a limit frame and a threaded handle to limit and fix the support frame, so that the support frame can be stably erected at the end of the bed. At the same time, the support frame can be rotated to the bottom of the bed, which is convenient for the user to store the support frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In the following, embodiments of the arm rehabilitation exerciser of the present utility model will be described with reference to the accompanying drawings.

[0022] Figures 1-4 An arm rehabilitation exerciser showing an embodiment of the present utility model includes a support frame 2 rotatably connected to the end of the bed tail of a hospital bed 1. At both ends of the bottom of the support frame 2, slidable limit frames 6 are provided. At the bottom of both sides of the support frame 2, threaded handles 7 are rotatably connected through bearings. The limit frames 6 are threadedly connected to the surface of the threaded handles 7. By the combined use of the limit frames 6 and the threaded handles 7, the support frame 2 is limited and fixed, enabling the support frame 2 to stand stably at the end of the hospital bed 1. At the same time, the support frame 2 can be rotated to the bottom of the hospital bed 1 for easy storage by the user. At both sides of the bottom of the inner cavity of the support frame 2, limit rods 8 are fixedly connected. The counterweight blocks 32 are slidably connected to the surface of the limit rods 8. A counterweight assembly 3 is arranged in the inner cavity of the support frame 2. At both sides of the top of the support frame 2, pull ropes 4 are provided. The rear ends of the pull ropes 4 are fixedly connected with bracelets 9. The counterweight assembly 3 includes fixed tubes 31 fixedly connected to both sides of the bottom of the inner cavity of the support frame 2. A plurality of counterweight blocks 32 are arranged in the inner cavity of the fixed tubes 31. The front ends of the pull ropes 4 are fixedly connected with connecting rings 35. A bolt pin 33 is rotatably connected to the inner cavity of the connecting ring 35. A nut sleeve 34 is welded to the front side of the counterweight block 32. The bolt pin 33 is threadedly connected to the inner cavity of the nut sleeve 34. At both sides of the top of the support frame 2, guide assemblies 5 are provided. The guide assembly 5 includes support wheels 51 fixedly connected to both sides of the top of the support frame 2. At both ends of the top of the rear side of the support frame 2, fixed frames 52 are fixedly connected. A steering wheel frame 53 is rotatably connected to the surface of the fixed frames 52. Two anti - detachment pulleys 54 are rotatably connected to the inner cavity of the steering wheel frame 53. The surface of the pull rope 4 is in rolling contact with the surface of the support wheel 51. The rear end of the pull rope 4 penetrates into the inner cavity of the steering wheel frame 53 and is in sliding contact between the two anti - detachment pulleys 54. By the combined use of the steering wheel frame 53 and the anti - detachment pulleys 54, the direction of the pull rope 4 is limited. At the same time, under the combined use of the fixed frame 52 and the steering wheel frame 53, the anti - detachment pulleys 54 can be adjusted automatically according to the pulling direction of the pull rope 4, thereby preventing the pull rope 4 from detaching from the surface of the anti - detachment pulleys 54 and ensuring the stability of the pull rope 4 during movement. At both ends of the top of the front side of the support frame 2, limit tubes 55 are fixedly connected. The pull rope 4 is arranged in the inner cavity of the limit tubes 55.

[0023] Working principle: When the utility model is used, the user rotates the support frame 2 so that the support frame 2 stands upright at the end of the bed 1, and then turns the threaded handle 7. The threaded handle 7 pushes the limit frame 6 through its surface thread, so that the bottom of the limit frame 6 contacts the top of the bed 1, thereby limiting and fixing the support frame 2. Then, the user threadably connects the bolt pin 33 to the inner cavity of the threaded sleeve 34 on the surface of the corresponding counterweight block 32 according to training needs. Then, the user pulls the hand ring 9, and the hand ring 9 drives the pull rope 4 to slide. During the sliding process, the pull rope 4 is guided by the support wheel 51 and the anti-slip pulley 54. During the pulling process, the pull rope 4 is used in conjunction with the connecting ring 35 and the bolt pin 33 to pull the counterweight block 32, so that the counterweight block 32 rises on the surface of the limit rod 8. Then, the pull rope 4 is released, so that the counterweight block 32 falls back under the action of gravity. The pull rope 4 is pulled back and forth, so that the user's arm can be trained.

[0024] To sum up: the arm rehabilitation exerciser, through the coordinated use of the support frame 2 and the counterweight assembly 3, counterweights the pulling force of the pull rope 4, and at the same time, through the coordinated use of the support frame 2 and the guide assembly 5, guides the pull rope 4. Then the user repeatedly pulls the pull rope 4, which can achieve the purposes of convenient use, adjustable counterweight and stable pulling.
