Description

Technical Field

[0001] The utility model relates to the technical field of medical exercise equipment, and particularly relates to an exercise assistance tool. Background Art

[0002] After breast cancer surgery, in order to prevent lymphoedema, patients usually need to do appropriate exercises. Among them, the hand needs to do fist clenching exercises, and the arm needs to do upward lifting exercises. However, patients need to gradually increase the height of arm lifting. The best training method is to stop for a period of time when the patient's arm is lifted to the limit position that can be tolerated to allow the body to adapt to this height. After adaptation, then lift the arm to a higher height, and so on to gradually recover. But because staying at the limit position that can be tolerated will cause continuous pain, it is very difficult for the patient to do this by himself. Therefore, it is necessary to rely on the help of others or on equipment. Relying on others will waste manpower and the stability is poor. It is not easy for the patient to control the lifted height by himself and is easy to exceed the limit, thus causing damage to the patient. Relying on equipment, the existing equipment has a relatively single function and can only simply exercise the fingers or lift the arm, but cannot exercise both at the same time, which takes more time. Content of the Utility Model

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide an exercise assistance tool, which effectively solves the problem that the existing device is inconvenient to exercise the hand and the arm at the same time.

[0004] The technical solution it adopts is that the utility model includes a hollow seat body. There are two Z-shaped blocks which are opposite left and right and can move up and down in the seat body. The two Z-shaped blocks are symmetrical left and right and can move relatively or away from each other. The outer ends of the two Z-shaped blocks extend out of the seat body, and rotatable swing boxes are respectively arranged at their opposite ends. Two ratchets which are distributed left and right and have a left and right axial direction are fixed in the Z-shaped block. The two ratchets are fixedly connected by a connecting column. The tooth directions of the two ratchets are opposite. A connecting sleeve which is coaxial with the ratchet and has a concave axial cross-section is slidably connected in the swing box. The ratchet is located in the connecting sleeve. Two pawls corresponding to the ratchet one by one are hinged in the connecting sleeve. A pull rope is arranged in the swing box. The upper end of the pull rope is fixedly connected with the connecting sleeve on its corresponding side. A plurality of connecting ropes which are distributed in the up and down direction are arranged on the swing box. The connecting ropes penetrate through the swing box and are fixedly connected with the pull rope.

[0005] The beneficial effect of the utility model is that when the patient's hand is straightened, the arm can be lifted upward but cannot fall. When the patient's hand makes a fist, it can fall but cannot be lifted upward. Therefore, when the patient is doing arm lifting exercises, he needs to cooperate with fist clenching exercises of the hand. Only by such cooperation can the arm lifting exercises be carried out normally. This changes the patient's usual simple arm lifting exercises and simple hand fist clenching exercises, saves time, improves the exercise efficiency and effect, and promotes the patient's early recovery.

[0012] The following further describes in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0013] As shown by Figures 1 to 6 , it includes a hollow seat body 1. Inside the seat body 1, there are two Z-shaped blocks 2 that are opposite left and right and can move up and down. The two Z-shaped blocks 2 are symmetric left and right and can move relative to or away from each other. The outer ends of the two Z-shaped blocks 2 extend out of the seat body 1, and rotatable swing boxes 3 are respectively provided at their opposite ends. Inside the Z-shaped blocks 2, two ratchets 4 that are distributed left and right and have a left and right axial direction are fixed. The two ratchets 4 are fixedly connected by a connecting column 5. The tooth directions of the two ratchets 4 are opposite. Inside the swing box 3, a connecting sleeve 6 that is coaxial with the ratchet 4 and has a concave axial cross-section is slidably connected. The ratchet 4 is located inside the connecting sleeve 6. Inside the connecting sleeve 6, two pawls 7 corresponding to the ratchet 4 one by one are hinged. Inside the swing box 3, a pull rope 8 is provided. The upper end of the pull rope 8 is fixedly connected to the connecting sleeve 6 on its corresponding side. On the swing box 3, a plurality of connecting ropes 9 are provided and are distributed in the up and down direction. The connecting ropes 9 penetrate through the swing box 3 and are fixedly connected to the pull rope 8.

[0014] In order to enable the two Z-shaped blocks 2 to move up and down and relative to or away from each other, a slider 10 is slidably connected inside the seat body 1. A left and right axial screw rod 11 is rotatably connected to the slider 10. The thread directions on the left and right sides of the screw rod 11 are opposite and are connected to the Z-shaped block 2 on its corresponding side. The rear end of the Z-shaped block 2 is located inside the seat body 1 and contacts the inner side wall of the seat body 1.

[0015] In order to limit the position of the slider 10, the rear end of the slider 10 extends out of the seat body 1. A plurality of limiting grooves 12 distributed in the up-and-down direction are formed at the rear end of the seat body 1. A limiting block 13 that can be inserted into the limiting groove 12 is slidably connected to the rear end of the slider 10.

[0016] In order to enable the swing box 3 to rotate, rotating rings 14 coaxial with the connecting column 5 are respectively fixed to the opposite ends of the two swing boxes 3. The connecting sleeve 6 is located inside the rotating ring 14.

[0017] In order to facilitate the control of the movement of the pawl 7, a compression spring is fixed between the connecting sleeve 6 and the swing box 3. The pawl 7 is fixedly connected to the connecting sleeve 6 through an elastic piece. A reversing column in contact with the pulling rope 8 is fixed inside the swing box 3. A pulling ring 15 is fixed to the connecting rope 9.

[0018] In order to enable the swing box 3 and the patient's arm to swing simultaneously, a plurality of straps 16 distributed in the up-and-down direction are respectively fixed to the front and rear ends of the swing box 3.

[0019] When the present utility model is in use, the initial state is that the swing box 3 is in the up-and-down direction. The pawl 7 far from the swing box 3 is engaged with the ratchet wheel 4, and the pawl 7 close to the swing box 3 is located directly above the connecting column 5 and is not engaged with the ratchet wheel 4 close to the swing box 3;

[0020] The patient sits on the seat body 1 with the back against the seat body 1. Push the limiting block 13 to the right to move the limiting block 13 out of the limiting groove 12, release the limit on the slider 10, move the slider 10 up and down. The slider 10 drives the screw rod 11 to move up and down, and the screw rod 11 drives the Z-shaped block 2 to move up and down. When the rotating ring 14 approaches the patient's shoulder and is located below the shoulder, stop moving the slider 10 and insert the limiting block 13 into the limiting groove 12 again, and the height of the Z-shaped block 2 is determined;

[0021] Rotate the screw rod 11. Since the Z-shaped block 2 contacts the side wall of the seat body 1, the Z-shaped block 2 cannot rotate. Therefore, when the screw rod 11 rotates, the two Z-shaped blocks 2 will move relatively under the action of the threads with different helix directions on both sides. When the swing box 3 contacts the patient's arm, stop rotating the screw rod 11. At this time, the distance between the two Z-shaped blocks 2 is determined under the action of the thread self-locking property. If the swing box 3 contacts the patient's back when the patient sits on the seat body 1, that is, the distance between the two Z-shaped blocks 2 is less than the shoulder width of the patient, the screw rod 11 can be rotated in the reverse direction first to move the two Z-shaped blocks 2 away from each other to adjust the distance between the two Z-shaped blocks 2, and then move the slider 10 to adjust the height of the Z-shaped block 2;

[0022] After adjusting the height of the Z-shaped block 2, tie the patient's arm to the swing box 3 with the strap 16, and let the patient's fingers pass through the pull ring 15 at the corresponding position, that is, the pull ring 15 that the patient's fingertips can just hook into. At this time, the patient can lift the arm upward. When the arm is lifted, the patient's hand is in a straight state. The swing box 3 drives the rotating ring 14 and the connecting sleeve 6 to rotate synchronously. Since the pawl 7 far from the swing box 3 cooperates with the ratchet wheel 4 at this time, the patient can normally lift the arm. When it is lifted to the limit position that the current body can bear, if the patient wants to maintain this height for a period of time, stop swinging upward. At this time, with the cooperation of the ratchet wheel 4 and the pawl 7 far from the swing box 3, the swing box 3 cannot swing downward, thus realizing the fixation of the lifted height;

[0023] When the patient wants to swing the arm downward back to the initial position, the patient's fingers hook the pull ring 15 to make a fist. The pull ring 15 moves under the pull of the fingers. The pull ring 15 pulls the pull rope 8 to move through the connecting rope 9. The pull rope 8 pulls the connecting sleeve 6 to move outward, so that the pawl 7 far from the swing box 3 disengages from the ratchet wheel 4, and the pawl 7 close to the swing box 3 engages with the ratchet wheel 4 close to the swing box 3. At this time, the patient can swing the arm downward, and cannot swing upward under the cooperation of the ratchet wheel 4 and the pawl 7. After the patient swings the arm downward, the patient can release the pull ring 15, that is, the fingers are opened. At this time, the connecting sleeve 6 moves outward under the action of the compression spring, so that the pawl 7 far from the swing box 3 engages with the ratchet wheel 4, and the pawl 7 close to the swing box 3 disengages from the ratchet wheel 4. At this time, the arm can be lifted again, that is, the arm can be lifted when the patient's fingers are opened, and the arm can be swung downward when the hand makes a fist. In this way, the finger clenching exercise is carried out while the arm is lifted, making the exercise more efficient and reliable.

[0024] The utility model has the advantages of simple structure, convenient operation, novel concept and strong practicability. Through the setting of the pawl, ratchet wheel, connecting sleeve, pull rope, compression spring, connecting rope and pull ring, the displacement of the pawl is driven by the patient's hand clenching, so as to realize the control of the one-way swing of the swing box, meet the exercise requirements of the patient for lifting the arm and clenching the fist, and enable the patient to fix the height after the arm swings, so that the patient can gradually adapt to the height of the arm swing, thereby improving the exercise effect. And multiple pull rings can meet the use of patients with different arm lengths. The use requirements of different patients are met through the screw rod, slider and Z-shaped block, increasing the practicability of the device.
