Description

Technical Field

[0001] The present invention relates to the field of wearable technologies, and particularly to a lower limb double-arch inner support rope suspension double-pulley load-reducing stepping device. Background Art

[0002] Standing requires certain muscle tension to be maintained. In addition, when standing, a person's lower limbs hang down, and the blood flow is less when standing without moving, which will cause a series of health problems, specifically as follows: 1. Effects on bones and muscles: Standing for a long time causes great pressure on the soles of the feet, directly affecting foot health. Moreover, the long-term support of both feet increases the pressure on various parts of the spine, resulting in unbalanced spinal stress and soft tissue fatigue, and then causing diseases in multiple parts such as the feet, neck, shoulders, waist, and back. Therefore, people who stand for a long time are at high risk of occupational musculoskeletal disorders; 2. Effects on lower limb venous blood vessels: When standing for a long time, due to the long vertical distance between the heart and the lower limbs, the blood vessel walls of the lower limbs need to bear an additional pressure load caused by the vertical distance. And the lumen of the venous blood vessels is thin, and the ability to resist pressure load is poor, so it is easily damaged, leading to varicose veins of the lower limbs.

[0003] In life, people such as teachers, nurses, surgeons, salespersons, waiters, and greeters need to stand for a long time. Especially in some industries that involve handling and long-distance walking, standing for a long time affects the physical health of workers. For this reason, we propose a lower limb double-arch inner support rope suspension double-pulley load-reducing stepping device to solve the above problems. Summary of the Invention

Detailed implementation manners

[0035] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings.

[0036] See Figures 1-9 , a lower limb double-arch inner support rope suspension double-pulley load-reducing stepping device, including a support plate 1 placed on the abdomen. The support plate 1 is supported by engineering plastic or aluminum alloy plates and is placed at a soft position on the abdomen during use. At the top of one side of the support plate 1, there is a edge plate 12. The edge plate 12 is arranged obliquely upward relative to the support plate 1, which increases the height of the fixed pulley 10 and at the same time keeps the fixed pulley 10 at a certain distance from the body, improving the comfort of the hand pulling the pull rope 6 and also avoiding friction between the pull rope 6 and the body, thus improving the comfort of using the device. On one side of the edge plate 12, two fixed pulleys 10 are fixed. By means of the fixed pulleys 10, the pulling direction of the pull rope 6 is changed, which is convenient for the hand to apply force and avoids the pull rope from knotting. On the outer sides of both sides of the two fixed pulleys 10, there are limit structures to control the length of the pull rope 6. After installation, the double-arch is kept in a bent and stressed state. Between the two fixed pulleys 10, there are two limit blocks 11 to separate the two pull ropes 6 and control the positions of the two pull ropes 6, avoiding the pull rope 6 being wound around the adjacent fixed pulley 10 and the other pull rope 6 or getting stuck on the adjacent fixed pulley 10 when the pull ropes are loosened or tightened. There are limit holes on the limit blocks 11. On one side of the support plate 1, there is a movable plate 16 with adjustable position. According to the length of the bow member 5 and the height of the user, the position of the movable plate 16 is adjusted, thereby adjusting the force-bearing position, making the double-arch in a suitable position, improving the support ability of the double-arch and the comfort of the user. On one side of the movable plate 16, there is a base 24. A rotating shaft is installed on the base 24. The two ends of the rotating shaft penetrate through the base 24 and extend to both sides of the base 24. At both ends of the rotating shaft, there are fish-eye bearings 17, which can rotate a certain angle towards the outside of the thigh while rotating back and forth, facilitating the spreading of the legs during use. On one side of the fish-eye bearing 17, there is a clamping sleeve 25. On one side of the clamping sleeve 25, there is a fixed column 23 for fixing the pull rope 6. The plug plate 37 is detachably connected inside the clamping sleeve 25. On the clamping sleeve 25, there is a first fixing member 19 for fixing the plug plate 37, and the upper connecting member 21 can be disassembled by loosening the first fixing member 19;

[0037] The lower end of the plug board 37 is connected to the upper connecting member 21. The lower part of the upper connecting member 21 is provided with a lower connecting member 27. One end of the connecting bow member 5 of the upper connecting member 21 and the lower connecting member 27 is bent outward. One end of the upper connecting member 21 and the lower connecting member 27 is provided with a jack 38. Both jacks 38 are installed with the bow member 5, which is convenient for the installation and disassembly of the bow member 5, improves the installation and disassembly efficiency of the bow member 5, and is convenient for carrying after combined installation and disassembly. The cross-section of the bow member 5 is flat elliptical, and the force application directions are the same after installation, and it will not tilt in other directions, improving the safety of the wearable device. The two bow members 5 are connected by an installation sleeve 48, reducing the length of the bow member 5 and being convenient for carrying. The upper connecting member 21 is provided with a second fixing member 22 for fastening the bow member 5, and the lower connecting member 27 is provided with a third fixing member 28 for fastening the bow member 5. Both ends of the bow member 5 are provided with positioning holes 47, and the positioning holes 47 correspond to the fourth fixing member 49, the second fixing member 22, and the third fixing member 28 respectively, improving the firmness of the bow member 5 after installation. The installation sleeve 48 is provided with a fourth fixing member 49 for fastening the bow member 5, and the bow member 5 is fixed after being installed, realizing the disassembly and installation of the device. The moving plate 16 is provided with a baffle mechanism. The baffle mechanism is located between the two upper connecting members 21. The baffle mechanism can control the position of the pull rope 6 and prevent the bow members 5 on both sides from colliding due to in-toe walking. One side of the lower connecting member 27 is fixed with two fixing plates 39, and a movable pulley 40 is installed between the two fixing plates 39, with stable support and effectively avoiding the pull rope from detaching from the movable pulley 40;

[0038] A drawstring 6 is fastened to a fixing post 23 on one side of a support plate 1. The drawstring 6 sequentially passes through a movable pulley 40, a baffle mechanism, a limiting hole, a fixed pulley 10, and a limiting structure and extends to the other side of the support plate 1. The drawstring 6 assists in bending a bow member 5 through a pulley block, thereby facilitating the bending of the legs during walking, reducing the force exerted by the legs. At the same time, the pulley block can also reduce the force exerted by the hands. A limiting bead 15 is fixed on the drawstring 6, and the limiting bead 15 corresponds to the limiting structure. After installation, when the bow member 5 is released, the limiting bead 15 on the drawstring 6 abuts against a limiting ring 9, keeping the bow member 5 bent. One end of the drawstring 6 is fixed with a handle 14. The handle 14 can be a horn handle during exercise, which can enable the hands to exert force evenly. A wire guiding device for limiting the drawstring 6 is provided on both bow members 5 on the same side. Due to the characteristics of the pulley block, the drawstring 6 forms two reciprocating lines after passing through the pulley block. The drawstrings 6 on the same side are located on the same wire guiding device. The drawstring 6 is connected in multiple sections through safety buckles. The same drawstring 6 is divided into multiple sections, which is convenient for later disassembly and placement. During use, it is connected through a safety buckle. A support block 41 is fixed to the bottom of the lower connecting member 27. When worn, the support block 41 abuts against the ground, conducting the force received by the double bow to the ground. Connecting blocks 42 are fixed to the outer sides of both lower connecting members 27. An installation groove is provided on one side of the connecting block 42, and a limiting groove 44 is provided on one side of the installation groove, facilitating the clamping of a limiting wheel 46 into the installation groove. The limiting groove 44 penetrates the side wall of the installation groove. A rotating rod 29 is hinged to the other side of the connecting block 42. One side of the rotating rod 29 and one side of the connecting block 42 are jointly connected with a tension spring 43, which can quickly close when the rotating rod 29 is opened by an external force and is not subject to force. One end of the rotating rod 29 is fixed with a limiting plate 30. The outer side of the limiting plate 30 is arc-shaped. The limiting plate 30 corresponds to the installation groove. The lowermost end of the limiting plate 30 is located at two-thirds of the position of the installation groove. The limiting plate 30 blocks the notch of the installation groove. A rotating block 45 is provided on one side of the limiting plate 30, forming a protrusion on one side of the limiting plate 30. When it is necessary to open the limiting plate 30, the rotating block 45 is hooked by the toes and rotated upward to open the notch of the installation groove. A limiting wheel 46 is provided in the installation groove. When the limiting wheel 46 is located in the installation groove, it cannot be opened from the inside under the action of the limiting plate 30. When installing the limiting wheel 46, the limiting wheel 46 abuts against one-third of the installation groove flowing out of the limiting plate 30. During installation, the limiting wheel 46 is moved forward. Due to the arc-shaped outer side of the limiting plate 30, under the action of the arc surface, the limiting plate 30 rotates upward, and the limiting wheel 46 enters the installation groove to complete the installation. One end of the limiting wheel 46 is fixed with a fixed shaft. One end of the fixed shaft penetrates the limiting groove 44 and extends to one side of the connecting block 42. A foot fixing member 32 is fixed to one side of the fixed shaft, facilitating foot wearing. After wearing, the position of the fixed shaft is located inside the toe of the foot, facilitating the user's body to lean forward and receive force. The foot fixing member 32 can be a footrest that can fix the toes, but the thickness should not be too thick. The bottom of the foot fixing member 32 and the bottom of the support block 41 are on the same horizontal plane, avoiding discomfort caused by uneven foot force.The bottom of the foot fixing part 32 is provided with an anti-skid rubber strip to improve the anti-skid ability when worn. A fastening belt 31 is fixed on one side of the foot fixing part 32. One end of the fastening belt 31 is detachably connected to the other side of the foot fixing part 32. The fastening belt 31 is fixed to the foot fixing part 32 by passing it around one side of the ankle. A waist safety sling 4 is provided at the lower part of the other side of the support plate 1 for wearing on the buttocks. An abdominal belt 3 is also provided on the other side of the support plate 1 for fixing on the abdomen. After installation, the force is transmitted to the body through the abdomen and buttocks. The abdominal belt 3 is fixed by the connecting belt 2 and the Japanese buckle. A flexible gasket is provided on the inner side of the abdominal belt 3. The flexible gasket corresponds to the support plate 1 to improve the comfort when worn. A shoulder strap is provided on one side of the abdominal belt 3 to reduce the deformation of the abdominal belt 3 when it is stressed. The first fixing part 19, the second fixing part 22 and the third fixing part 28 are all adjustment screws or plum handle rubber head screws, which are convenient for quick installation and removal of the wearable device, thereby improving the portability of the device.

[0039] In the present invention, the baffle mechanism includes two baffles 18 fixed on the movable plate 16, which can block the bow 5 from deflecting inward, thereby preventing the bows 5 on both sides from colliding. The two baffles 18 are rotatably connected to multiple connecting rods 20. When the pull rope 6 hits the connecting rod 20 and slides on the connecting rod 20, it can drive the connecting rod 20 to rotate, thereby reducing the wear on the pull rope 6. The pull rope 6 is located between the two baffles 18.

[0040] In the present invention, a slide groove 13 is provided on one side of the support plate 1, and the movable plate 16 is installed in the slide groove 13 through a slider. The movable plate 16 slides on the support plate 1 through the slide groove 13 and the slider. The movable plate 16 is provided with a hexagonal tightening structure 26 for fixing the movable plate 16. The tightness of the slider is adjusted by adjusting the hexagonal tightening structure 26 to tighten the movable plate 16.

[0041] In the present invention, the limiting structure includes two mounting plates 8 fixed on the edge plate 12, the two mounting plates 8 are located on the outside of the two fixed pulleys 10, an adjusting rod 7 is fixed on the mounting plates 8, a limiting ring 9 is fixed at one end of the adjusting rod 7, and the limiting ring 9 can control the position of the pull rope 6 and also control the length of the pull rope 6 between the two pulleys.

[0042] In the present invention, the wire device includes a fastener 33 detachably connected to two bows 5. The fastener 33 can be a clip clamped on the bow 5. Second connecting ropes 36 are connected to both fasteners 33. The second connecting ropes 36 have a certain elasticity. Two limiting tubes 34 are provided at one end of the second connecting rope 36. Two adjacent limiting tubes 34 are connected by a first connecting rope 35. The second connecting rope 36 is connected to one of the limiting tubes 34 to limit the position of the limiting tube 34. After the pulling rope 6 passes through the limiting tube 34, friction of the pulling rope 6 is avoided. After the same pulling rope 6 is deflected by the movable pulley 40, it is located on one side of the bows 5 on the same side. The pulling ropes 6 on the same side penetrate through two limiting tubes 34.

[0043] As can be seen from the above technical solutions, during use, the safety buckle is used to connect the pull rope 6. One end of the same control pull rope 6 is connected to the fixed column 23 on one side of the support plate 1, and then passes through the baffle mechanism of the moving plate 16 and the wire device on the bow member 5 in sequence to prevent the pull rope 6 from getting entangled during work. The pull rope 6 then passes through the movable pulley 40, the wire device on the bow member 5, the baffle mechanism, and the limit hole on the other side of the support plate 1, and extends to the other side of the support plate 1 through the fixed pulley 10 and the limit structure on the other side of the support plate 1. The pull rope 6 is connected by a safety buckle between the baffle mechanism and the wire device, which is convenient for disassembling the wearable device. The pull rope 6 on the left side is controlled by pulling the pull rope 6 with the handle 14 on the right side, and the pull rope 6 on the left side is used to control the movable pulley 40 on the right side. During use, the user first wears the waist safety sling 4 on the buttocks, and then fixes the abdominal belt 3 on the abdomen, so as to fix the support plate 1 on the abdomen 3. The shoulder strap can be connected to the abdominal belt 3 to fix the abdominal belt 3 secondarily. Then, the foot fixing member 32 is worn on the foot and fixed on the foot by the fastening belt 31. The two bow members 5 are installed on an installation sleeve 48 and fixed by the fourth fixing member 49.
