Description

Technical Field

[0001] This invention relates to the field of training device technology, specifically to a pelvic floor muscle function exercise device for women with pelvic floor relaxation. Background Technology

[0002] Pelvic floor muscle trainers are divided into internal and external types. External trainers indirectly exercise the pelvic floor muscles by using the legs, especially the thighs, to perform opening and closing movements. For female users, pelvic floor muscle training is an important muscle group that supports and maintains the balance of intra-abdominal pressure. By exercising the thigh opening and closing movements, the contraction and relaxation ability of the pelvic floor muscles can be indirectly strengthened, thereby improving their function and endurance. Most existing external pelvic floor muscle exercisers that utilize the opening and closing movements of the human leg use electronic or mechanical counting methods to allow users to monitor the number of opening and closing movements in real time. However, exercisers need to observe the number of movements and rely on their subjective will to decide whether to stop exercising. This method is easily affected by human factors and cannot ensure accurate and consistent exercise counts. Exercisers need to actively operate the device, such as pressing a button or actively stopping the movement. This requires exercisers to pay attention and operate actively at all times, which can easily cause inconvenience and fatigue. At the same time, this type of exercise device cannot be well used by some women who are still in the recovery period of pelvic floor muscles after surgery. If these women lack self-safety awareness during exercise, they may over-exercise, which will not only lead to poor exercise results, but may even cause accidental injury to muscles or limbs. It can be seen that the existing pelvic floor muscle exercise devices of this type have poor overall safety and flexibility. Therefore, this invention proposes a pelvic floor muscle exercise device for women with pelvic floor relaxation, in order to make up for and improve the shortcomings of the prior art.

Using the positioning bracket, which is a semi-circular arc with a smaller diameter at the top and a larger diameter at the bottom and is made of rubber, the user can place the inner thigh close to the upper surface of the positioning bracket during use. The position of the positioning bracket allows the user to refer to the placement and posture of their own legs when performing pelvic floor muscle exercises, thereby ensuring the correct posture and comfort of the user when performing pelvic floor muscle exercises.

[0013] Compared with known public technologies, the technical solution provided by this invention has the following beneficial effects: This invention utilizes the insertion of a locking shaft and a shaft hole to promptly lock and limit the perforated sliding shaft and the curved surface combination plate, automatically pausing the pelvic floor muscle exercise. Compared to existing technologies that use electronic or mechanical counting and rely on the exerciser's subjective will to pause exercise for appropriate rest after observing the number of exercises, this solution can automatically lock the curved surface combination plate to actively pause the exercise without requiring the exerciser to constantly monitor the number of exercises. This provides the pelvic floor muscles with timely rest and recovery time, avoiding over-fatigue and muscle injury, and helps improve the effectiveness of pelvic floor muscle function training. At the same time, it can also significantly reduce the risk of accidental injury during pelvic floor muscle exercise, thereby ensuring the safety of the pelvic floor muscle function training process. Meanwhile, as the exerciser repeatedly performs pelvic floor muscle exercises, some muscle groups in the upper thighs will be intermittently contacted by the combination bar. The upper end of the bar is spherical, and by using the contact between the spherical surface of the bar and the exerciser's thighs, the muscle groups in the thighs can be activated in a targeted manner. This helps to strengthen and shape the leg muscles, improve muscle strength and firmness, and stimulate the thigh muscles through the contact motion of the bar, thereby promoting blood circulation and oxygen supply. This helps to improve the metabolic activity of the muscles and reduce the exerciser's fatigue. During pelvic floor muscle exercises, the pushing motion of the lumbar support reminds the exerciser to maintain an upright posture at all times. This helps correct the common forward leaning or hunching that occurs when exercising in a seated position, allowing the spine to maintain its normal physiological curvature and reducing discomfort and fatigue in the lower back. Maintaining an upright posture requires the involvement of core muscles, including abdominal, back, and pelvic floor muscles. The pushing motion of the lumbar support forces the user to maintain the correct sitting posture through coordinated contraction of the core muscles, thereby enhancing the core stability of the pelvic floor muscles and the strength of the abdominal muscles. In addition, the positioning support is a semi-circular shape made of rubber with a smaller diameter at the top and a larger diameter at the bottom. When using it, the user can place the inner thigh close to the upper surface of the positioning support. The position of the positioning support can help the user refer to the placement and posture of their own legs when performing pelvic floor muscle exercises, thereby ensuring the correct posture and comfort of the user when performing pelvic floor muscle exercises. At the same time, the through grooves in the positioning support also help the user to dissipate heat around the inner thigh during exercise. Attached Figure Description

A locking shaft 219 is evenly fixedly connected to the end of the displacement shaft 217 near the perforated sliding shaft 21. A shaft hole 221 is evenly opened at the position of the perforated sliding shaft 211 corresponding to the locking shaft 219. A boosting spring 220 is fixedly connected to the upper outer wall of the ring rod 218. The end of the boosting spring 220 away from the ring rod 218 is fixedly connected to the upper outer wall of the locking shaft 219. The assist spring 220 is initially in a compressed state, and the length of the assist spring 220 after releasing its elastic force allows the locking shaft 219 to be inserted into the shaft hole 221. The surfaces of the grooves in the arc-shaped twin groove plate 22 are all polished, and the lengths of the grooves are equal. The pawl 28 with a shaft and a torsion spring is movably inserted into the upper end face of the rope winding power shaft 27 via a rotating shaft. A second torsion spring is sleeved on the part where the pawl 28 with the shaft and the rope winding power shaft 27 are movably inserted. In use, the user can temporarily separate the pawl 28 with the shaft and the ratchet drive disc 29 by moving the pawl 28 with the shaft upward to stretch the second torsion spring.

The side of the displacement block 213 near the upper limit groove of the fixed rod frame 212 is slidably connected to the limit groove through the limit rod. Specifically, the pawl with shaft torsion spring 28, ratchet drive disc 29, synchronous belt 210, belt shaft 211, and displacement block 213 can be implemented as follows: When the pawl 28 with the shaft torsion spring rotates counterclockwise, it can drive the ratchet drive disc 29 to rotate one revolution, and then drive the disc shaft 211 to rotate one revolution through the synchronous belt 210. After the disc shaft 211 rotates one revolution, it can drive the displacement block 213 to move upward by a constant distance. The displacement block 213 can move upward by ten constant distances on the outer wall of the disc shaft 211. After the displacement block 213 moves ten constant distances, it will cause the magnetic plate 216 and the magnetic plate 2131 to be at the same horizontal position. It is worth noting that the aforementioned "ten constant distances" correspond to the exerciser performing ten pelvic floor muscle exercises. Magnetic plate 216 and magnetic plate 2131 have opposite magnetic poles, and the final position of magnetic plate 2131 after moving upward is within the magnetic attraction range of their opposite magnetic poles.

The outer surface of the lumbar support 47 is covered with a soft sponge layer to ensure the comfort of the user's back. The lumbar support 47 is located in the middle of the upper surface of one side of the main support plate 1.

[0018] The working principle and steps are as follows: Initial state constraints: The perforated sliding shaft 21 is located at the ends of both sides inside the arc-shaped twin slot plate 22, and the magnetic plate 2131 of the displacement block 213 is located at the bottom of the shaft 211 with disc. The principle and steps of an adjustable self-locking exercise mechanism: First, the exerciser can place the main support plate 1 horizontally on the desired exercise area. Then, the exerciser places both legs on either side of the curved combination plate 13. At this time, the exerciser can use the position of the positioning support 310 to adjust the position of their legs accordingly, ensuring that their thighs correspond to the positioning support 310. Then, the exerciser can slowly squat down and sit on the upper surface of the main support plate 1. After sitting down, the exerciser can lean their back against the surface of the lumbar support 47. At this time, the exerciser can make minor adjustments to the position of their limbs to ensure that the upper part of their thighs can be in contact with the upper surface of the positioning support 310. At the same time, the exerciser also needs to ensure that the middle part of their thighs can contact and be in contact with the outer wall of the curved combination plate 13. This ensures that the exerciser has a correct posture when performing pelvic floor muscle exercises, and also improves the overall comfort of the exerciser during the pelvic floor muscle exercise process. At this point, the exerciser can gradually apply external force to the outer walls of both sides of the curved composite plate 13 using their leg muscles, causing the curved composite plate 13 to rotate around the fixed central axis 12 as a fulcrum and move in opposite directions. During this process, the torsion spring connected to the rotating connection between the fixed central axis 12 and the curved composite plate 13 will undergo elastic deformation under the force. When the curved composite plate 13 moves to its maximum distance in opposite directions, the exerciser can gradually reduce the external force applied to the curved composite plate 13. At this time, under the rebound force of the torsion spring, the curved composite plate 13 and the exerciser's thigh will gradually move back to the initial position. By repeating the above steps, the exerciser can perform pelvic floor muscle training. Simultaneously, during the pelvic floor muscle exercises performed by the trainees, as the curved composite plate 13 rotates around the fixed central axis 12 in a direction of opposing movement, the perforated sliding shaft 21 will also be simultaneously slid along the groove trajectory of the curved twin-groove plate 22 near the side of the horizontal plate 24, gradually moving towards the center position. Specifically, this can be described as follows: Figure 6 As shown, and in addition... Figure 4 As shown, as the perforated sliding shaft 21 moves, the sliding protrusion 25 will slide synchronously. The movement of the sliding protrusion 25 will cause the portion of the power rope 26 wrapped around the outer wall of the rope-winding power shaft 27 to gradually move away from the outer wall of the rope-winding power shaft 27. During this process, under the frictional force between the power rope 26 and its outer wall, the rope-winding power shaft 27 will rotate clockwise, and the torsion spring at the lower end of the rope-winding power shaft 27 will undergo elastic deformation. Simultaneously, the clockwise rotation of the rope-winding power shaft 27 will also synchronously cause the shaft-mounted torsion spring pawl 28 to move. For example... Figure 8 As shown, at this time, the pawl 28 with shaft torsion spring is in contact with the inner wall of the ratchet drive disk 29 and is moving in a circular motion. Based on the meshing state of the pawl 28 with shaft torsion spring and the ratchet drive disk 29 at this time, and since the ratchet drive disk 29 is connected to the outer wall of the horizontal plate 24 through the plate body rotation, the ratchet drive disk 29 will not rotate during the clockwise rotation of the pawl 28 with shaft torsion spring driven by the rope winding power shaft 27. Conversely, as the exerciser and the curved composite plate 13 reset, the rope-winding power shaft 27 will rotate in the opposite direction under the rebound force of the torsion spring, thus retracting the power rope 26 back to its outer wall. After the rope-winding power shaft 27 rotates in the opposite direction (counterclockwise), the torsion spring pawl 28 on the upper surface of the rope-winding power shaft 27 will drive the ratchet drive disc 29 to rotate counterclockwise. The ratchet drive disc 29 then drives the pulley shaft 211 to rotate synchronously via the synchronous belt 210. As the pulley shaft 211 rotates, because the internal center of the displacement block 213 and the pulley shaft 211 form a ball screw structure, the rotation of the pulley shaft 211 will cause the displacement block 213 and the magnetic plate 2131 to gradually move upwards synchronously. During this process, if... Figure 8 As shown, since the side of the displacement block 213 closest to the fixed rod frame 212 is slidably connected to the limiting groove opened on the surface of the fixed rod frame 212 through the limiting rod, the displacement block 213 and the magnetic plate 2131 will always move vertically upward. As the trainee repeatedly trains, during each reset of the arc surface combination plate 13, it will drive the belt shaft 211 to rotate in one direction, thereby driving the displacement block 213 and the magnetic plate 2131 to move upward by a fixed distance. Thus, after the exerciser has been exercising their pelvic floor muscles for a period of time, as the shaft 211 rotates and the displacement block 213 and magnetic plate 2131 move upwards until magnetic plate 2131 and magnetic plate 216 are on the same horizontal line, the magnetic attraction between the opposite magnetic poles of magnetic plate 2131 and magnetic plate 216 will cause magnetic plate 216 to gradually move closer to magnetic plate 2131. Simultaneously, this will cause the horizontal plate 215 to slide along the rectangular hole in the perforated horizontal bar 214. This, in turn, will cause the cylindrical shaft to move synchronously, gradually moving away from and eventually away from the circular hole on one side of the displacement shaft 217. (See reference for details.) Figure 15 As shown; At this time, since the assisting spring 220 is initially compressed, and the length of the assisting spring 220 after releasing its elastic force allows the locking shaft 219 to be inserted into the shaft hole 221, as the cylindrical shaft moves away from the circular hole, the displacement shaft 217 will be caused to move horizontally along the upper part of the ring rod 218 under the rebound force of the assisting spring 220, thereby causing the locking shaft 219 to be inserted into the shaft hole 221. After the locking shaft 219 is inserted into the shaft hole 221, the perforated sliding shaft 21 will be limited and unable to continue moving. That is, the arc-shaped combination plate 13 fixedly connected to it will also be unable to move, making it impossible for the exerciser to continue exercising. Therefore, when the exerciser is performing pelvic floor muscle exercises, and after a period of exercise, the locking shaft 219 and the shaft hole 221 can be used to lock and limit the perforated sliding shaft 21 and the arc-shaped combination plate 13 in a timely manner, thus automatically pausing the exerciser's pelvic floor muscle exercise. Compared with the existing technology that uses electronic or mechanical counting and then relies on the exerciser's subjective will to pause the exercise for appropriate rest after observing the number of exercises, this solution can automatically lock the arc-shaped combination plate 13 to actively pause the exercise without the exerciser's real-time attention to the number of exercises. This provides the exerciser's pelvic floor muscles with timely rest and recovery time, avoids over-fatigue and muscle injury, helps improve the exercise effect of pelvic floor muscle function, and can also significantly reduce the risk of accidental injury during pelvic floor muscle exercises, thereby ensuring the safety of the pelvic floor muscle function exercise process. And after the exercisers have finished resting, at this time... Figure 8 and Figure 9 As shown, since the pawl 28 with a shaft torsion spring is movably inserted into the upper end face of the rope winding power shaft 27 via a rotating shaft, and a second torsion spring is sleeved at the part where the pawl 28 with the shaft torsion spring is movably inserted into the rope winding power shaft 27, during use, the exerciser holds the pawl 28 with the shaft and moves it upward to stretch the second torsion spring, which temporarily separates the pawl 28 with the ratchet drive disc 29. At this time, the pawl 28 with the shaft torsion spring is not engaged with the ratchet drive disc 29. Subsequently, the exerciser manually moves the displacement block 213 down from the upper outer wall of the disc shaft 211 to return it to its initial state. During this process, the disc shaft 211 will... It will rotate clockwise, which in turn drives the ratchet drive disc 29 to rotate clockwise via the synchronous belt 210. Since the torsion spring pawl 28 is disengaged from the ratchet drive disc 29 at this time, the clockwise rotation of the ratchet drive disc 29 will not drive the rope winding power shaft 27 to rotate. Then, the exerciser can manually reverse the horizontal plate 215 with shaft, the cylindrical shaft, the displacement shaft 217 and the locking shaft 219 to start the second exercise. In the process of resetting the displacement block 213 and other components, the exerciser can have an independent operating experience, which can improve the exerciser's operating experience of this device.

[0019] The principle and steps of limb positioning mechanisms: At the same time, such as Figure 9 , Figure 10 , Figure 11As shown, in the above process, the rope-winding power shaft 27 rotates clockwise under the friction between the power rope 26 and its outer wall. Simultaneously, it also causes the transmission shaft 31 and the toothed disc 32 to rotate. As the toothed disc 32 rotates, it drives the helical toothed slide plate 33, which meshes with it, to slide horizontally along the horizontal groove on the outer wall of the bracket 23. This causes the displacement crank 34 and the assist block 35 to move synchronously via the helical toothed slide plate 33. As the assist block 35 moves horizontally, its inclined surface gradually contacts and presses against the central convex shaft plate 3. The ball-shaped column at the center of the bottom surface of the 6-axis causes the central convex shaft plate 36 and the limiting side plate 37 to gradually move upward along the outer wall of the limiting sleeve spring shaft 38. At the same time, it compresses the return spring on the upper outer wall of the limiting sleeve spring shaft 38, which in turn drives the combined rod 39, composed of multiple rectangular rods evenly distributed, to move upward synchronously. After the combined rod 39 moves upward, it will abut against the muscle group around the upper thigh of the exerciser. When the arc-shaped combined plate 13 returns to its original position, it will drive the assist block 35 to return to its original position in the opposite direction. At this time, the central convex shaft plate 36 and the combined rod 39 will automatically move downward and return to their original position under the rebound force of the return spring. In this way, as the exerciser repeatedly performs pelvic floor muscle exercises, some muscle groups in the upper thigh will be intermittently contacted by the combination bar 39. The upper end of the bar 39 is spherical, and by using the contact between the spherical surface of the bar and the exerciser's thigh, the muscle groups in the thigh can be specifically activated, which is beneficial for strengthening and shaping the leg muscles, improving muscle strength and firmness. At the same time, the contact movement of the bar stimulates the muscles in the thigh, thereby promoting blood circulation and oxygen supply, which helps to improve the metabolic activity of the exerciser's muscles and reduce the exerciser's fatigue.

[0020] The principle and steps of the lower back support and stimulation mechanism: Synchronously, when the limiting side plate 37 moves upward along the outer wall of the limiting sleeve spring shaft 38, it will also simultaneously cause the assisting plate 41 to move upward, as can be described in detail below. Figures 11 to 14As shown, as the assist plate 41 moves upward, it continuously presses against the power plate 42, causing the end of the power plate 42 near the assist plate 41 to rotate upward around the upper end of the bracket 43. Since the bracket 43 is located near the assist plate 41, based on the lever principle, as the end of the power plate 42 near the assist plate 41 rotates upward, the end of the power plate 42 away from the assist plate 41 rotates downward, thereby driving the contact shaft 44 to rotate downward. As the contact shaft 44 moves downward, it will abut against the inclined part of the side block 45. As the contact shaft 44 continues to move downward, the side block 45 will drive the adjustment base plate 46 and the waist support 47 to slide horizontally towards the side closer to the assist plate 41. During this process, the adjustment base plate 46 slides along the reset groove opened on the surface of the main support plate 1. At the same time, during the sliding process, the reset slider will press the reset spring in the reset groove. As the waist support 47 moves, it will abut against the back of the exerciser. Therefore, during pelvic floor muscle exercises, the pushing motion of the lumbar support 47 can remind exercisers to maintain an upright posture at all times. This helps correct the common forward leaning or hunching that occurs when exercising in a seated position, allowing the spine to maintain its normal physiological curvature and reducing discomfort and fatigue in the lower back. Maintaining an upright posture requires the involvement of core muscles, including abdominal, back, and pelvic floor muscles. The pushing motion of the lumbar support 47 requires users to coordinate the contraction of their core muscles to maintain the correct sitting posture, thereby enhancing the core stability of the pelvic floor muscles and the strength of the abdominal muscles.

[0021] Once the exerciser has finished exercising, the user can stand up from above the main support plate 1.
