[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0024] This embodiment provides a portable hand rehabilitation and care device, such as... Figures 1-4 As shown, the portable hand rehabilitation and care device includes a box body 1 and a box cover 2 fixedly installed at the opening of the box body 1. A roller 3 is rotatably connected inside the box body 1. A pull cable 4 is wound on the roller 3, one end of which is fixedly connected to the roller 3. The other end of the pull cable 4 passes through the side wall of the box body 1 and is fixedly connected to a finger ring 41 for wearing on the finger that needs care. A coil spring 5 is provided inside the box body 1 between the roller 3 and the box cover 2 for resetting the roller 3. One end of the coil spring 5 is connected to the roller 3, and the other end is connected to the box cover 2 through an adjustment mechanism 6 that can adjust the tension of the coil spring 5. A wristband 7 for wearing on the wrist is fixedly installed on the side of the box body 1 away from the box cover 2.
[0025] The adjusting mechanism 6 comprises a rotating shaft 61 rotatably installed at the center of the box cover 2 and connected with one end of the inner ring of the coil spring 5, a plurality of ratchet teeth 611 fixedly connected with the top end side of the rotating shaft 61 and arranged in an annular array, a push piece 62 abutting against the side of the ratchet teeth 611 for preventing the rotating shaft 61 from rotating back, a rectangular connecting rod 621 fixedly connected with the top of the push piece 62 and penetrating through the top surface of the box cover 2, a button 63 fixedly connected with the top end of the rectangular connecting rod 621, a compression spring 622 sleeved outside the rectangular connecting rod 621 and connected with the box cover 2 and the button 63 at both ends, and a knob 64 rotatably connected with the top surface of the box cover 2 and fixedly connected with the top end of the rotating shaft 61, wherein the rectangular connecting rod 621 is slidingly connected with the box cover 2.
[0026] In use, the user wears the wrist strap 7 on the wrist, then pulls the pull rope 4 to make the finger ring 41 sleeved on the finger to be nursed, when the pull rope 4 is pulled, the winding roller 3 rotates, the coil spring 5 is further compressed to store energy, and after the finger is relaxed, the reaction force of the coil spring 5 retracts the pull rope 4 and the finger ring 41, so that the finger can be nursed in this way; when it is needed to adjust the tightness of the coil spring 5, the knob 64 is rotated to drive the rotating shaft 61 to rotate, thereby driving the one end of the inner ring of the coil spring 5 connected with the rotating shaft 61 to rotate synchronously, so that the number of turns of the coil spring 5 is changed, the initial damping of the coil spring 5 is increased, and the difficulty of pulling the pull rope 4 is increased, and at the same time, under the action of the push piece 62, the push piece 62 is deformed and displaced when the arc surface of the ratchet teeth 611 contacts the push piece 62, and the end of the tooth of the ratchet teeth 611 after passing contacts the end of the push piece 62 again to prevent the rotating shaft 61 from rotating back, and the initial damping of the coil spring 5 is gradually increased by continuously rotating the knob 64. When it is needed to reset, the button 63 is pressed to drive the push piece 62 to move downward through the rectangular connecting rod 621 until the push piece 62 is out of the thickness range of the ratchet teeth 611, after the push piece 62 is out of contact, the rotating shaft 61 is reset under the reaction force of the coil spring 5, the initial damping of the coil spring 5 returns to zero, and after the button 63 is released, the rectangular connecting rod 621 drives the push piece 62 to reset to the action range of the ratchet teeth 611 under the action of the compression spring 622.
[0027] The one end of the inner ring of the coil spring 5 has a clamping plate 52, the side of the rotating shaft 61 has a clamping frame 612 clamped with the clamping plate 52, the one end of the outer ring of the coil spring 5 is wound into a winding drum 51, and the winding roller 3 has a connecting column 31 inserted with the winding drum 51, so that the two ends of the coil spring 5 are respectively installed and fixed with the rotating shaft 61 and the winding roller 3, the connection is convenient, and the detachable design facilitates subsequent maintenance and replacement.
[0028] It should be noted that the thickness of the ratchet 611 is equal to the thickness of the push piece 62, and the length of the rectangular link 621 is greater than the thickness of the ratchet 611 to ensure that the push piece 62 can be driven by the rectangular link 621 and be separated from the ratchet 611; the thickness of the ratchet 611 is equal to the thickness of the push piece 62, which ensures that the push piece 62 can form a stable resistance when abutting against the side surface of the ratchet 611 to prevent the rotation of the rotating shaft 61; and the length of the rectangular link 621 is greater than the thickness of the ratchet 611, which ensures that when the button 63 is pressed, the push piece 62 can be driven by the rectangular link 621 and be smoothly separated from the ratchet 611 to release the one-way resistance to the rotating shaft 61.
[0029] Specifically, the box body 1 has at least three clamping heads 11 arranged in a ring array on one end side close to the box cover 2, and the box cover 2 has a clamping sleeve 21 corresponding to the position of each clamping head 11; this design enables the box body 1 and the box cover 2 to be tightly connected together to form a closed space for accommodating and protecting the components such as the winding roller 3 and the pull cable 4, and also facilitates subsequent maintenance and replacement.
[0030] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
