Description

Technical Field

[0001] The utility model particularly relates to an autonomous exercise power-assisting belt. Background Art

[0002] Limb exercises are widely used for bedridden patients. Some patients who are bedridden due to leg injuries, foot injuries, lower limb paralysis or cerebral thrombosis, etc., cannot move their legs and feet independently due to long-term bed rest. Long-term static rest will cause muscle atrophy and slow recovery of the injured part's function, especially after ankle and knee joint injuries. If they are not active, the joint movement will be restricted. After the injured joint is fixed for two weeks, the connective tissue fibers will fuse, resulting in loss of joint function.

[0003] Currently, there are two ways for patients to exercise their lower limbs. One is for patients to use their hands to rotate their legs and feet back and forth, bend and straighten their legs to move their ankles, knees and leg muscles, or to hold on to the bed rails to turn over and exercise. This type of exercise is an active exercise by the patient and requires upper limb muscle strength to reach about level 4. The other way of exercise is for caregivers to assist patients in moving the ankles, knees and leg muscles of their legs and feet, but this method requires caregivers to operate and is more troublesome.

[0004] Existing hospitals use an exercise belt, one end of which is put on the patient's foot and the other end is held by the patient. The patient exercises the legs by pulling the exercise belt. This method can achieve the purpose of exercise, but can only be used for patients to exercise their lower limbs. It cannot assist patients in turning over and exercising their upper limbs, and its function is relatively simple.

[0005] The Chinese patent: CN114404870A, named: A self-controlled lower limb exercise belt, records that it includes a sheath, a resistance band and a leg strength band. The sheath is a long strip made of flexible material, and the two ends of the long strip are fixedly connected to the foot binding strap and the leg binding strap. There are connecting buckles at both ends of the sheath. The resistance band is made of elastic material, and multiple grips are provided along the length direction of the leg strength band.

[0006] As shown in the attached figure of patent CN114404870A, the technical solution of this patent is to hold the grip part and pull it hard when in use, and the connection buckle near the toes applies tension to the toes, automatically pulling the toes toward the calf to the extreme position and ensuring that the resistance band is straight. Then the patient straightens the instep while kicking the legs, achieving the effect of exercising the patient's lower limbs. This solution is an existing commonly used technology, which can achieve the effect of exercising the lower limbs, but cannot assist the patient in turning over and exercising the upper limbs. The function is relatively simple. At the same time, the exercise belt is troublesome to store when not in use and is easily tangled together, making it inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0033] The following is a combination of the appended examples of the present invention Figure 1-13 , the technical solutions in the embodiments of the present utility model are described in detail. Example

[0034] like Figure 1 and 2 As shown, an autonomous exercise assisting belt comprises an assisting belt body 1, a gripping portion 2 and a foot cover 3, wherein the foot cover 3 is detachably connected to one end of the assisting belt body 1, and the other end of the assisting belt body 1 can be controllably retracted in the gripping portion 2.

[0035] The gripping part 2 is composed of a shell 4, a bundling component 5, a length control component 6, a tension training module 7 and a turntable 8. The function of the gripping part 2 is to facilitate the patient's holding. The turntable 8 is installed in the shell 4 through a main shaft 41. One end of the assisting belt body 1 is wrapped around the turntable 8. The assisting belt body 1 is wrapped around the turntable 8 through the bundling component 5, and the length of the assisting belt body 1 bundled on the turntable 8 can be controlled and adjusted through the length control component 6. The tension training module 7 is arranged on both sides of the shell 4. The tension training module 7 is controllably coordinated with the turntable 8 in the shell 4. The torsion spring 75 in the tension training module 7 after cooperating with the turntable 8 provides resistance to the rotation of the turntable 8. When actively exercising the upper limbs, a certain force needs to be applied to pull the assisting belt body 1 out of the turntable 8 to complete the active exercise of the upper limbs.

[0036] like Figure 1 and 2 As shown, the power-assisting belt body 1 is a flat braided belt made of nylon, which has good tensile strength and durability as a whole. The power-assisting belt body 1 includes a connecting ring 12 and a pull ring 12 arranged on the power-assisting belt body 1.

[0037] The connecting ring 11 is opened at the front end of the power-assisting belt body 1, and the whole is a rectangular hole. The main function of the connecting ring 11 is to install the connecting buckle 13, and the foot cover 3 is connected to the power-assisting belt body 1 through the connecting buckle 13. The connecting buckle 13 is an existing common quick-hanging buckle and can be purchased and used directly.

[0038] The material of the connecting ring 11 is the same as that of the power-assisting belt main body 1. The connecting ring 11 is in a circular shape as a whole. One part of the connecting ring 11 is sewn together with the power-assisting belt main body 1, and multiple groups of connecting rings 11 are provided on the power-assisting belt main body 1. In this embodiment, 3 groups of connecting rings 11 are preferably provided. The function of the connecting ring 11 is to facilitate the patient to pull the connecting ring 11 in sequence to perform lower limb exercises or to use force to assist in turning over exercises when the patient is exercising his lower limbs or turning over.

[0039] When the power-assisting belt main body 1 is contracted, in order to facilitate the contraction of the power-assisting belt main body 1 and prevent obstruction by the connecting ring 11, a snap 14 is fixed on the power-assisting belt main body 1 near the connecting ring 11. The female snap 14 is fixed on the power-assisting belt main body 1, and the male snap 14 is fixed on the connecting ring 11. This fixing method is the existing technology. After the connecting ring 11 is connected to the power-assisting belt main body 1 through the snap 14, the connecting ring 11 is laid flat on the power-assisting belt main body 1 as a whole. In this way, when the power-assisting belt main body 1 is contracted, the connecting ring 11 can be contracted together, which facilitates the contraction of the power-assisting belt main body 1 and is easy to use.

[0040] Definition: In this embodiment, based on the power-assisting belt body 1, the end connected to the connecting buckle 13 is the front end (or head end), and the end connected to the turntable 8 is the rear end (or end end).

[0041] like Figure 1 and 2 As shown, the shell 4 includes two left and right shells connected together by screws. One end of the left and right shells has a gripping end 42 for the patient to hold. When the left and right shells are closed, there is a cavity for installing the turntable 8 in the middle of the left and right shells. At the same time, a main shaft 41 is inserted in the middle of the cavity, and the turntable 8 is sleeved on the outside of the main shaft 41.

[0042] In order to facilitate the contraction of the power-assisting belt body 1, a rectangular hole penetrating the shell 4 is opened on the side of the shell 4 away from the gripping end 42. This rectangular hole is named the power-assisting belt outlet 44. The power-assisting belt body 1 passes through the power-assisting belt outlet and is wound around the turntable 8.

[0043] In order to facilitate the fixation of the main shaft 41, a circular fixing ring is sleeved on the middle part of the main shaft 41. The fixing ring and the main shaft 4 are screwed and cannot move relative to each other. Four L-shaped fixing pins are arranged on the fixing ring along the radial direction of the fixing ring and are integrated with the fixing ring. The four fixing pins are distributed at intervals and are respectively connected to the housing 4 with screws to achieve the fixation of the main shaft 4 on the housing 4.

[0044] like Figure 2 、 3 As shown in Figures 4, 5, 6, 8 and 9, the turntable 8 includes a guard plate 81 and a connecting pipe 82. There are two guard plates 81, which are respectively sleeved on both ends of the connecting pipe 82, and the guard plates 81 and the connecting pipe 82 are connected together by screws. The connecting pipe 82 is sleeved on the main shaft 41, and the turntable 8 can rotate around the main shaft 41.

[0045] The guard plate 81 is a circular plastic plate. A circular through hole is opened in the middle of the guard plate 81 through the center of the circle. The diameter of the circular through hole is the same as the outer diameter of the connecting pipe 82. In order to facilitate the connection of the two guard plates 81 together, an annular boss is protruding perpendicular to the outside of the guard plate 81 on the circular end face of the guard plate 81. This boss is named the annular connecting platform 83. A circular through hole is opened on the surface of the annular connecting platform 83. The two sets of guard plates 81 are connected together by screws through the circular through hole. The end of the power-assisting belt body 1 is fixed on the arc surface of the annular connecting platform 83 and is wrapped around the annular connecting platform 83.

[0046] The connecting pipe 82 is a circular plastic pipe with a certain wall thickness. An annular boss is protruding outwards from the outer arc surface of the connecting pipe 82. The connecting pipe 82 and the guard plate 81 are fixed together by screws through the annular boss.

[0047] In order to facilitate the installation of the disc spring 51 in the bundling assembly 5, an annular groove is concave on the two annular end faces of the connecting tube 82 through the center of the connecting tube 82, and this groove is named functional groove 85. A disc spring 51 made of stainless steel sheet is placed in one of the functional grooves 85. The inner end of the disc spring 51 is fixed on the main shaft 41, and the outer end is fixed on the inner wall of the connecting tube 82 (this fixing method can be screw fixing or the existing commonly used fixing method). When the power-assisting belt main body 1 wrapped around the turntable 8 is pulled out, the turntable 8 will rotate accordingly. At this time, the disc spring 51 will be compressed by force. When the force applied to the power-assisting belt main body 1 is released, the turntable 8 will reset under the action of the disc spring 51, completing the bundling of the power-assisting belt main body 1, thereby completing the pulling out and bundling of the power-assisting belt main body 1.

[0048] In order to control the length of the assist belt body 1 that is pulled out or gathered, so that the assist belt body 1 gathered on the turntable 8 can be locked at any position, a length control component 6 is also provided in the shell 4. At the same time, a plurality of limit blocks 86 are provided on the outer surface of the guard plate 81 at intervals along the center of the guard plate 81. The limit blocks 86 cooperate with the locking blocks 65 in the length control component 6 to limit the rotation of the turntable 8.

[0049] The length control component 6 includes an unlocking button 61, a connecting rod 62 and an unlocking button limiting mechanism 63. The connecting rod 62 is hinged inside the shell 4. One end of the connecting rod 62 is connected to the unlocking button 61. There is a locking block 65 at the other end of the connecting rod 62. The locking block 65 can be movably cooperated with the upper limit block 86 of the guard plate 81 to realize the control of the rotation of the turntable 8.

[0050] The connecting rod 62 is a rod with an "L"-shaped cross section. The cross bar of the connecting rod 62 is hinged on the shell 4, and there is a slightly larger rectangular block at the end of the cross bar, which is named the locking block 65. The vertical rod of the connecting rod 62 passes through the outer wall of the shell 4 and is exposed to the outside, and there is also an unlocking button 61 for the user to press on the exposed vertical rod. Pressing the unlocking button 61 can drive the connecting rod 62 to rotate along the hinge, adjust the cooperation between the locking block 65 and the limit block 86, and then control the rotation of the turntable 8, thereby completing the adjustment of the contraction length of the power-assisting belt body 1 on the turntable 8.

[0051] In order to improve the stability of the cooperation between the locking block 65 and the upper limit block 86 of the guard plate 81, two cross bars are provided on the connecting rod 62, and a locking block 65 is provided at the end of each cross bar. The two locking blocks 65 correspond to a guard plate 81 respectively, and each locking block 65 can cooperate with the upper limit block 86 of the guard plate 81 to achieve position limitation. When no additional force is applied to the connecting rod 62, in order to make the locking block 65 and the upper limit block 86 of the guard plate 81 always in a coordinated state, a connecting block is connected between the two cross bars of the connecting rod 62, and a spring is fixed on the connecting block. This spring is named the first return spring 64. The other end of the first return spring 64 is against the inner wall of the shell. Under the action of the first return spring 64, the locking block 65 always cooperates with the limit block 86 to limit the rotation of the turntable 8.

[0052] The function of the unlock button limit mechanism 63 is to limit the position of the unlock button 61, release the cooperation between the locking block 65 and the upper limit block 86 of the guard plate 81, so that the turntable 8 can rotate freely, and then through the cooperation of the tension training module 7, it is convenient for the patient to perform upper limb tension training.

[0053] The unlock button limiting mechanism 63 includes a limiting plate 66 hinged to the outside of the shell 4 and two limiting cards 67 arranged on the left and right side shells. There is a limiting claw 68 on the limiting card 67. By pressing the limiting plate 66, the limiting plate 66 can rotate along the hinge and press on the outside of the unlock button 61, applying pressure to the unlock button 61, releasing the cooperation between the locking block 65 and the upper limit block 86 of the guard plate 81. At the same time, the limiting claw 68 can limit the limiting plate 66 at this time, so that it always remains in a state of applying force to the unlock button 61, so that the locking block 65 and the limiting block 86 are always in a released state.

[0054] The limiting plate 66 is a rectangular plate, one end of which is hinged to a hinge platform on the housing 4 , and a torsion spring is sleeved on the hinge shaft. When the limiting plate 66 applies force to the unlocking button 61 , the torsion spring is compressed.

[0055] The limit card 67 is a rod with a rectangular cross-section. A triangular limit claw 68 is fixed to the end of the limit card 67. When the limit plate 66 is pressed, the edge of the limit plate 66 will squeeze the limit claw 68, thereby causing the limit card 67 to shift until the limit plate 66 is completely stuck under the limit card 67.

[0056] In order to release the restriction of the limit claw 68 on the position of the limit plate 66, an unlocking paddle 69 is fixed integrally with the limit card 67 at the upper end of the limit card 67 near the limit claw 68. Turning the unlocking paddle 69 can drive the limit card 67 to bend, thereby releasing the restriction of the limit claw 68 on the position of the limit plate 66. At this time, the limit plate 66 is reset under the action of the torsion spring to release the force applied to the unlocking button 61. At this time, the connecting rod 62 rotates the locking block 65 to re-engage with the limit block 86.

[0057] Regarding the contraction and stretching process of the power-assisting belt body 1: when it is necessary to pull out the power-assisting belt body 1, first press the unlocking button 61 to release the cooperation between the locking block 65 and the limit block 86, and then pull the power-assisting belt body 1. At this time, the turntable 8 rotates and the power-assisting belt body 1 is pulled out. At the same time, the coil spring 51 is compressed. After it reaches the appropriate length, the unlocking button 61 is released. At this time, under the action of the first return spring 64, the locking block 65 and the limit block 86 are re-engaged. At this time, the turntable 8 cannot rotate;

[0058] When it is necessary to tighten the power-assisting belt body 1, first press the unlocking button 61 to release the cooperation between the locking block 65 and the limit block 86, and then loosen the power-assisting belt body 1. At this time, the turntable 8 rotates under the action of the coil spring 51, and then the power-assisting belt body 1 is wound on the turntable 8.

[0059] like Figure 1 、 12As shown in Figure 13, the foot cover 3 includes an upper ring 31, a middle ring 32 and a lower ring 33, wherein the upper ring 31 and the middle ring 32 have the same size, the lower ring 33 is slightly smaller, the ends of the middle ring 32 and the lower ring 33 are hinged together, and the upper ring 31 and the middle ring 32 are connected together by a V-shaped connecting belt 34.

[0060] The main function of the foot cover 3 is to fix the patient's foot to prevent the foot from slipping and affecting the exercise during lower limb exercise. The upper ring 31, the middle ring 32 and the lower ring 33 are all "C"-shaped. The straight rods at both ends of the upper ring 31, the middle ring 32 and the lower ring 33 are made of hard plastic, and the middle part is made of flexible rubber. The outside of the upper ring 31, the middle ring 32 and the lower ring 33 are wrapped with skin-friendly fabric to prevent the feet from getting hurt.

[0061] The V-shaped connecting belt 34 is made of the same material as the power-assisting belt body 1 , and its main function is to connect the upper ring 31 and the middle ring 32 . At the same time, a connecting ring 11 is provided at one end of the V-shaped connecting belt 34 , through which the foot cover 3 can be connected to the connecting buckle 13 on the power-assisting belt body 1 .

[0062] In order to improve the stability of the foot cover 3 on the patient's foot, a connecting cloth 35 is provided between the middle ring 32 and the lower ring 33. The connecting cloth 35 is made of skin-friendly material. One end of the connecting cloth 35 is fixed to the inner side of the middle ring 32 along the contour of the middle ring 32, and the other end is fixed to the outer side of the lower ring 33 along the contour of the lower ring 33. When the middle ring 32 and the lower ring 33 are parallel, the connecting cloth 35 is in a folded state. When the middle ring 32 and the lower ring 33 are opened along the hinge, the connecting cloth 35 will unfold to form a cloth pocket. The connecting cloth 35 can hold the patient's heel to prevent the foot from sliding during lower limb exercise, thereby improving the stability of the foot cover 3 on the patient's foot.

[0063] like Figure 7 、 8 As shown in Figures 9, 10 and 11, the tension training module 7 includes a sleeve 71, an adjusting knob 72 and a driven ring 74. The adjusting knob 72 is fixed to one end of the sleeve 71, and the driven ring 74 is sleeved on the other end of the sleeve 71 and can rotate freely along the sleeve 71. A torsion spring 75 is sleeved on the outside of the sleeve 71, and one end of the torsion spring 75 is connected to the driven ring 74, and the other end is connected to the sleeve 71. When the driven ring 74 rotates, the torsion spring 75 is compressed.

[0064] The main function of the tension training module 7 is to cooperate with the turntable 8. The spiral direction of the torsion spring 75 in the tension training module 7 is the same as the rotation direction of the turntable 8. When the power-assisting belt main body 1 is pulled out, the turntable 8 rotates, and the torsion spring 75 in the tension training module 7 applies resistance to the turntable 8. It is necessary to appropriately increase the applied force so that the applied force is greater than the torsional force of the torsion spring 75 to drive the turntable 8 to rotate and pull out the power-assisting belt main body 1, thereby realizing the patient's active tension exercise of the upper limbs. In order to achieve different exercise effects, the patient can adjust different sizes of force according to needs. A tension training module 7 is provided on each side of the shell 4. By changing the number of tension training modules 7 and the turntable 8, the difficulty of pulling out the power-assisting belt main body 1 during upper limb tension exercise can be adjusted, thereby achieving different exercise effects.

[0065] The sleeve 71 is a circular plastic tube. The inner diameter of the sleeve 71 is the same as the outer diameter of the main shaft 41. The sleeve 71 can be sleeved on the end of the main shaft 41. In order to facilitate the position fixation of the sleeve 71, five rectangular position fixing blocks 73 are fixed at intervals on the arc surface of the sleeve 71 near the end of the adjusting knob 72. The position fixing blocks 73 cooperate with the upper limit groove on the shell 4 to achieve the position fixation of the sleeve 71.

[0066] The driven ring 74 is a circular plastic ring. The inner diameter of the driven ring 74 is slightly smaller than the outer diameter of the sleeve 71. Five rectangular blocks are protruding from the arc surface of the driven ring 74. These rectangular blocks are named driven blocks 77. The five driven blocks 77 are evenly distributed on the driven ring 74. In order to facilitate the cooperation between the driven blocks 77 on the driven ring 74 and the turntable 8, five arc-shaped blocks 84 are protruding from the inner side wall near the end of the functional groove 85 of the connecting tube 82. The interval between two adjacent blocks 84 is slightly larger than the size of the driven block 77. The driven block 77 can be stuck in the interval between two adjacent blocks 84. When the turntable 8 rotates, the driven ring 74 can be driven to rotate under the action of the driven block 77.

[0067] In order to facilitate the installation of the tension training module 7, a circular through hole is opened on the left and right side shells of the shell 4 near the main shaft 41. The diameter of the circular through hole is equal to the outer diameter of the sleeve 71. At the same time, on the outer sides of the left and right side shells, a circular limiting ring 43 is fixed near the circular through hole. Five rectangular grooves are provided on the inner side surface of the limiting ring 43 along the radial inward direction of the limiting ring 43. These grooves are named first limiting grooves 45. The five first limiting grooves 45 are evenly distributed on the limiting ring 43. The position fixing block 73 on the sleeve 71 can be stuck in the first limiting groove 45, so that the driven block 77 on the driven ring 74 is always in a mating state with the turntable 8.

[0068] In order to facilitate the release of the cooperation between the driven block 77 and the turntable 8, five rectangular bosses are protruding along the outline of the limiting ring 43 on the outer annular surface of the limiting ring 43, and a rectangular groove is concave inwardly near the rectangular boss on the inner side surface of the limiting ring 43. This groove is named the second limiting groove 46. At the same time, a second return spring 76 is also provided in the functional groove 85. One end of the second return spring 76 rests on the driven ring 74, and the other end rests on the connecting pipe 82. Pressing and turning the adjusting knob 72 can move the position fixing block 73 out of the first limiting groove 45, and the position fixing block 73 is stuck in the second limiting groove 46, thereby releasing the cooperation between the driven block 77 and the turntable 8.

[0069] When the lever 74 is in the unlocked position, the lever 74 is in the unlocked position, and the second lever 74 is in the unlocked position, so that the lever 74 can be unlocked.
