Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a pelvic floor muscle trainer with adjustable resistance and angle. Background Technology

[0002] The pelvic floor muscles are an important muscle group that maintains the normal physiological position of the pelvic organs and enables them to perform their normal physiological functions. To train these muscles, pelvic floor muscle training devices have been developed. Currently, training devices for the pelvic floor muscles consist of two hinged frames connected by a torsion spring. The free ends of the frames have plates that fit against the legs. During training, the plates fit against the legs, and the frames swing back and forth under the clamping force of the legs.

[0003] However, different people have different levels of pelvic floor muscle strength, thus requiring training devices with varying resistance to achieve better training results. Furthermore, as users continue to use the device and their pelvic floor muscle strength increases, they also need to use pelvic floor muscle training devices with greater resistance to further enhance their strength. Traditional pelvic floor muscle training devices, however, do not have adjustable resistance, making it impossible to achieve these goals.

[0004] Meanwhile, with traditional pelvic floor muscle trainers, as the legs tighten during use, the contact area between the legs and the plate gradually decreases because the angle of the plate cannot be adjusted, and the angle between the two increases, which leads to the pelvic floor muscle trainer slipping off.

[0006] The resistance adjustment assembly includes: a height-adjustable variable diameter component, a knob, and a return spring. The torsion spring is sleeved on the variable diameter component. At least the portion of the variable diameter component that contacts the torsion spring is a cone with a continuously changing diameter. One end of the variable diameter component abuts against the knob, and the other end is connected to the return spring. When the knob is rotated in different directions, the variable diameter component rises or falls. The variable diameter component is provided with a limiting component that contacts the connecting arm, so that the variable diameter component rotates together with the connecting arm.

[0007] A further improvement is that the part of the knob that contacts the connecting arm has mutually cooperating protrusions and recesses.

[0008] A further improvement is that the knob has a stepped component on its bottom outer periphery, the stepped component has protrusions or recesses, and the connecting arm that contacts the stepped component has a mating structure that engages with the protrusions or recesses on the stepped component.

[0009] A further improvement is that the lower surface of the knob has a first inclined surface with continuously varying height, and the top surface of the variable diameter component has a second inclined surface that cooperates with the first inclined surface.

[0010] A further improvement is that at least two functional components are symmetrically arranged on the lower surface of the knob, the lower surface of the functional components is the first inclined surface, and a functional groove is provided at the corresponding position of the functional component on the upper surface of the variable diameter component, the bottom surface of the functional groove is the second inclined surface.

[0011] A further improvement is that a guide post is provided inside the connecting arm corresponding to the bottom end of the variable diameter component, the bottom end of the variable diameter component is sleeved on the guide post, and the return spring is provided inside the guide post.

[0014] A further improvement is that the top of the connecting seat is provided with a platform extending in the direction of the connecting arm, and the tray is installed on the platform. The center point of the connection between the platform and the tray is located in the middle of the two connecting arms, and the line connecting the two center points is parallel to the rotation plane of the two connecting arms.

[0015] A further improvement is that the mounting groove is an oblong groove arranged along the length of the connecting arm, and the end of the connecting seat is disposed in the oblong groove via a rotating shaft.

[0016] A further improvement is that the tray is rotatably mounted on the connecting seat, and the tray can rotate in a plane about the central axis of the connecting seat.

[0017] The beneficial effects of this utility model are:

[0018] The pelvic floor muscle trainer with adjustable resistance and angle provided by this utility model adjusts the length of the elastically deformable part of the torsion spring by raising and lowering the variable diameter component, thereby adjusting the torsion spring torque. This allows the resistance between the two connecting arms to meet the different usage needs of different users. At the same time, the support plate is rotatably mounted on the mounting groove through the connecting seat on the back, so that the angle of the support plate can follow the user's movements during use, ensuring that the support plate is always in complete contact with the legs and preventing slippage.

[0034] Example 1

[0035] like Figure 1 and Figure 2 As shown, this utility model provides a pelvic floor muscle trainer with adjustable resistance, comprising two connecting arms 1 and two support plates 2. One end of the two connecting arms 1 is connected together by a torsion spring 3, which is the first end. The other end of the connecting arm 1 is the second end. The first ends 11 of the two connecting arms 1 are rotatably connected together. Each of the second ends 12 of the two connecting arms 1 is provided with a support plate 2, and a torsion spring 3 is provided at the connection point. When no external force is applied, under the elastic force of the torsion spring 3, the second ends of the two first connecting arms 1 open to both sides, forming a figure-eight shape. When an external force is applied to the support plates 2, as the external force increases, the two connecting arms 1 rotate around the connection point at the first end, and the two support plates 2 move closer to each other. A resistance adjustment component 4 is provided at the second end 12 of each connecting arm 1.

[0036] like Figure 2As shown, the resistance adjustment assembly 4 includes: a height-adjustable variable diameter component 41, a knob 42, and a return spring 43. The torsion spring 3 is sleeved on the variable diameter component 41. A connecting arm 1 is connected to the extension of each end of the torsion spring 3. When the two connecting arms 1 are clamped under external force, the portion between the two ends of the torsion spring 3 undergoes elastic deformation with a reduced diameter. When the external force is removed, the torsion spring 3 returns to its original shape. At least the portion of the variable diameter component 41 in contact with the torsion spring 3 is a cone with a continuously changing diameter. This cone can be a regular cone or an inverted cone. One end of the variable diameter component 41 abuts against the knob 42, and the other end is connected to the return spring 43. When the knob 42 rotates in different directions, the variable diameter component 41 rises or falls under the action of the return spring 43. The longitudinal section of the variable diameter component 41 is approximately T-shaped, with the vertical portion being the variable diameter section and the horizontal portion being a functional platform. The bottom surface of the knob 42 abuts against and interacts with this functional platform. Furthermore, the edge of the horizontal functional platform has an upwardly extending wall 412, which is clearance-fitted with the connecting arm 1. Thus, during the lifting and lowering of the variable diameter component 41, the wall 412 cooperates with the vertical structure within the connecting arm 1 to achieve a guiding function (e.g., ...). Figure 2 and Figure 7 As shown,).

[0037] When using this trainer, if it is necessary to increase the resistance, the variable diameter part 41 is raised or lowered by turning the knob 42. As a result, the part of the torsion spring 3 that abuts against the variable diameter part 41 becomes longer. That is, the part of the torsion spring 3 that can undergo elastic deformation with a smaller diameter becomes shorter, and the elastic force of the torsion spring 3 becomes greater, so that the resistance increases when the two connecting arms 1 are clamped.

[0038] like Figure 2 As shown, in order to avoid changes in resistance that are not intended by the user due to the knob 42 and the variable diameter component 41 not rotating in the same direction during use, the variable diameter component 41 is provided with a limiting component 5 that contacts the connecting arm 1. The limiting component 5 is used to keep the variable diameter component 41 rotating with the connecting arm 1 where the knob is located, while not restricting the up and down movement of the variable diameter component 41.

[0039] like Figure 3As shown, in order to allow the tray 2 to rotate at an angle that adjusts according to the user's use, in this technical solution, a mounting groove 9 is provided at the second end 12 of the connecting arm 1. The mounting groove 9 is perpendicular to the length extension direction of the connecting arm 1 and is located on the outer side of the rotation direction of the connecting arm 1. The tray 2 is rotatably mounted in the mounting groove 9 via a connecting seat 10 connected to the back side. Its rotation direction can be a plane along the length direction of the connecting arm 1, and its rotation plane is parallel to the rotation plane of the connecting arm 1. Preferably, the connecting seat 10 inside the mounting groove 9 has a protruding rotating shaft 101, and the connecting arm 1 has a circular groove or hole for engaging the rotating shaft 101; or the inner wall of the connecting arm 1 inside the mounting groove 9 has a cylindrical protrusion towards the connecting seat 10, and the connecting seat 10 corresponding to the cylindrical protrusion has a groove for engaging the cylindrical protrusion. These structures enable the tray to move in the second direction, ensuring that the tray always fits completely against the legs and prevents slippage. At the same time, the size of the mounting slot opening limits the rotation angle of the connecting seat, thus acting as a limit and preventing the tray from rotating too much upward, which could cause the trainer to slip off.

[0040] The adjustable pelvic floor muscle trainer provided by this utility model adjusts the length of the elastically deformable part of the torsion spring by raising and lowering the variable diameter component, thereby adjusting the torsion spring torque and allowing the resistance between the two connecting arms to meet the different usage needs of different users.

[0041] like Figure 5 As shown, to prevent relative rotation between the knob 42 and the reducing component 41 during use, a further improvement to this technical solution is that the part of the knob 42 that contacts the connecting arm 1 is provided with a mutually cooperating protrusion and recess 421. This protrusion or recess can be circumferentially arranged. Since the return spring 43 pushes upward against the reducing component 41, and the reducing component 41 pushes upward against the knob, the protrusion or recess on the knob 42 and the corresponding recess or protrusion on the connecting arm 1 can be vertically aligned and locked together. This design not only prevents relative rotation between the knob and the reducing component during use, but also provides clear vibration feedback when the protrusion slides into and out of the recess during resistance adjustment, resulting in a superior user experience for this training device.

[0042] like Figure 5 and Figure 6 As shown, in order to fix the knob and prevent relative rotation between the knob and the reducing component during use, a further improvement of this technical solution is that the knob 42 has a laterally extending stepped component 422 on the outer periphery of its bottom. The upper surface of the stepped component 422 has a protrusion or recess 421, and the connecting arm 1, which contacts the stepped component 422, has a mating structure 13 that engages with the protrusion or recess 421 on the stepped component 422 (e.g., ...). Figure 10(As shown). The mating structure 13 is as follows: if the stepped member 422 is a protrusion, then the mating structure 13 is a depression; if the stepped member 422 is a depression, then the mating structure 13 is a protrusion. Whether it is a protrusion or a depression, there are multiple protrusions and they are evenly distributed circumferentially.

[0043] like Figure 5-9 As shown, a further improvement is made whereby the lower surface of the knob 42 has a first inclined surface 6 with continuously varying height, and the top surface of the variable diameter component 41 has a second inclined surface 7 that cooperates with the first inclined surface 6, with the first inclined surface 6 and the second inclined surface 7 abutting against each other. When the knob 42 is turned, the first inclined surface 6 and the second inclined surface 7 rotate relative to each other, thereby pushing the variable diameter component 41 down or, with the cooperation of the return spring 43, moving the variable diameter component 41 up, thus adjusting the length of the torsion spring 3 that abuts against the variable diameter component 41, thereby adjusting the length of the elastically deformable part of the torsion spring 3 and thus adjusting the elastic force of the torsion spring 3.

[0044] like Figure 5 and Figure 6 As shown, in order to ensure that the force applied by the knob 42 to the reducing component 41 is symmetrical and parallel to the central axis, and to avoid the reducing component 41 tilting due to a single force, a further improvement of this technical solution is that at least two functional components 423 are symmetrically provided on the lower surface of the knob 42. These functional components 423 extend downwards along the lower surface of the knob 42. The lower surface of each functional component 423 is a first inclined surface 6 with continuously varying height. A functional groove 411 is provided at the corresponding position of each functional component 423 on the upper surface of the reducing component 41. The bottom surface of the functional groove 411 is a second inclined surface 7. The functional component 423 is an arc shape concentric with the knob 42, and correspondingly, the functional groove 411 is also an arc shape concentric with the knob 42.

[0045] like Figure 2 As shown, to prevent the variable diameter component 41 from tilting and to ensure smoother up-and-down movement, a further improvement of this technical solution is that a vertically extending guide post 8 is provided inside the connecting arm 1 corresponding to the bottom end of the variable diameter component 41, and a blind hole extending upward from the bottom end is provided inside the bottom of the variable diameter component 41. The variable diameter component 41 is sleeved on the guide post 8 through the blind hole, and the guide post 8 is hollow. The reset spring 43 is placed inside the guide post 8, with one end abutting against the inside of the guide post 8 and the other end abutting against the blind hole at the bottom of the variable diameter component 41, providing an upward elastic force when the variable diameter component 41 resets upward.

[0046] A further improvement is that the limiting member 5 is a limiting protrusion, and the connecting arm 1 corresponding to the limiting protrusion is provided with a strip-shaped limiting groove extending longitudinally along the central axis of the variable diameter member 41. The limiting protrusion is embedded in the limiting groove, so that when the connecting arm rotates, the variable diameter member can rotate together.

[0047] Alternatively, the limiting member 5 is a strip-shaped limiting groove or limiting hole extending longitudinally along the central axis of the variable diameter member 41, and the connecting arm 1 is provided with a corresponding limiting protrusion extending into the limiting member 5.

[0048] Example 2

[0049] The difference between this embodiment and Embodiment 1 is that:

[0050] In order to enable the tray 2 to rotate in accordance with the user's use, in this technical solution, a mounting groove 9 is provided at the second end 12 of the connecting arm 1. The opening direction of the mounting groove 9 is perpendicular to the length extension direction of the connecting arm 1 and is located on the outer side of the rotation direction of the connecting arm 1. The tray 2 is rotatably installed in the mounting groove 9 through the connecting seat 10 connected to the back. Its rotation direction can be a plane along the length direction of the connecting arm 1, and its rotation plane is parallel to the rotation plane of the connecting arm 1; or a spherical universal joint structure is formed between the connecting seat 10 and the mounting groove 9, thereby realizing the multi-directional following of the tray 2.

[0051] In this embodiment, the pelvic floor muscle trainer with adjustable resistance and angle has a support plate that is rotatably mounted on the mounting slot via a connecting seat on the back. This allows the angle of the support plate to move with the user during use, ensuring that the support plate always fits completely against the legs and prevents slippage. At the same time, the size of the opening of the mounting slot can limit the rotation angle of the connecting seat, thus acting as a limit and preventing the support plate from rotating too much upward, which could cause the trainer to slip off.

[0052] Example 3

[0053] If the forces exerted by the two support plates 2 on the pelvic floor muscle trainer are not in the same plane during use, rotation around the central axis is likely to occur, leading to slippage of the trainer. To solve this problem, a further improvement of this technical solution is: a pelvic floor muscle trainer with adjustable resistance and angle, comprising: two connecting arms 1 and two support plates 2. One end of the two connecting arms 1 connected together by a torsion spring is the first end, and the other end of the connecting arm 1 is the second end. The first ends 11 of the two connecting arms 1 are rotatably connected together, and the second ends 12 of the two connecting arms 1 are respectively provided with a support plate 2, and a torsion spring is provided at the connection point. When no external force is applied, under the elastic force of the torsion spring, the second ends of the two first connecting arms 1 open to both sides, presenting a figure-eight shape; when an external force is applied to the support plates 2, as the external force increases, the two connecting arms 1 rotate around the connection point of the first end, and the two support plates 2 move closer to each other.

[0054] In order to enable the tray 2 to rotate in accordance with the user's use, in this technical solution, a mounting groove 9 is provided at the second end 12 of the connecting arm 1. The opening direction of the mounting groove 9 is perpendicular to the length extension direction of the connecting arm 1 and is located on the outer side of the rotation direction of the connecting arm 1. The tray 2 is rotatably installed in the mounting groove 9 through the connecting seat 10 connected to the back. Its rotation direction can be a plane along the length direction of the connecting arm 1, and its rotation plane is parallel to the rotation plane of the connecting arm 1; or a spherical universal joint structure is formed between the connecting seat 10 and the mounting groove 9, thereby realizing the multi-directional following of the tray 2.

[0055] As shown in the figure, the top of the connecting seat 10 is provided with a platform 20 extending towards the connecting arm 1, and the back of the tray 2 is fixedly or movably mounted on the platform 20. When the tray 2 and the platform 20 are fixedly connected, the tray 2, the platform 20, and the connecting seat 10 can be integrally formed. The center point of the connection between the platform 20 and the tray 2 is located in the middle of the two connecting arms 1, and the line connecting the two center points is parallel to the rotation plane of the two connecting arms 1. Thus, during use, the forces acting on the two trays 2 are on one plane, and therefore axial rotation will not occur.

[0056] Meanwhile, since the platform 20 extends towards the opposite connecting arm 1, and the center point of the connection between the platform 20 and the tray 2 is located in the middle of the two connecting arms 1, the outer edge of the platform 20 in the direction of the opposite connecting arm 1 will inevitably exceed the middle of the two connecting arms 1 and cover part of the opposite connecting arm 1. This achieves the limitation of the opposite connecting arm 1, so that the movement angle of the two connecting arms 1 can only be from the maximum to 0 degrees, and will not rotate to a negative angle. This avoids the connecting arm 1 rotating too much and hitting the back of the opposite tray 2, causing damage to the connection of the tray 2 connecting seat 10.

[0057] Example 4

[0058] In order to enable the tray 2 to rotate in accordance with the user's use, in this technical solution, a mounting groove 9 is provided at the second end 12 of the connecting arm 1. The opening direction of the mounting groove 9 is perpendicular to the length extension direction of the connecting arm 1 and is located on the outer side of the rotation direction of the connecting arm 1. The tray 2 is rotatably installed in the mounting groove 9 through the connecting seat 10 connected to the back. Its rotation direction can be a plane along the length direction of the connecting arm 1, and its rotation plane is parallel to the rotation plane of the connecting arm 1; or a spherical universal joint structure is formed between the connecting seat 10 and the mounting groove 9, thereby realizing the multi-directional following of the tray 2.

[0059] A further improvement is that the mounting groove 9 is an oblong groove arranged along the length of the connecting arm 1. A rotating shaft perpendicular to the rotation plane of the connecting arm 1 is installed in the oblong groove. If the rotating shaft is fixedly installed in the oblong groove, a through hole is opened at the end of the connecting seat 10, and the rotating shaft passes through the through hole, so that the connecting seat 10 can rotate around the rotating shaft. At the same time, the swing angle of the connecting seat 10 can be limited by adjusting the size of the gap between the oblong groove and the connecting seat 10 during manufacturing. The distance between the rotating shaft and the end of the oblong groove can be adjusted as needed during manufacturing, which can also realize the adjustment of the swing angle range of the connecting seat 10.

[0060] In another embodiment, the rotating shaft is fixedly installed at the bottom of the connecting seat 10, and both ends of the rotating shaft are inserted into the grooves on the inner wall of the waist-shaped groove. The ends of the rotating shaft and the grooves can be clearance fit, or bearings can be fixedly installed in the grooves on the inner wall of the waist-shaped groove, and the ends of the rotating shaft are installed on the bearings, thereby realizing the free rotation of the rotating shaft.

[0061] Example 5

[0062] To accommodate different usage angles of the trainer, this embodiment further improves upon embodiment four by rotatably mounting the tray 2 on the connecting seat 10, and allowing the tray 2 to rotate in a plane around the central axis of the connecting seat 10. This allows the connecting arm to be aligned with or opposed to the thigh during use. Specifically, the rotation of the tray 2 can be achieved preferably in the following two ways:

[0063] The first type: The back of the tray 2 has a raised cylinder, and the top of the cylinder is connected to a disc. The connecting seat 10 has a groove, and the opening of the groove is designed to be narrowed, that is, the narrowed opening of the groove fits precisely into the cylinder, and the narrowed opening of the groove encloses the disc in the groove, so that the disc will not fall out of the groove and can rotate freely.

[0064] The second type: The back of the tray 2 is provided with a protruding cylinder, and the connecting seat 10 is provided with a groove, and a bearing is fixedly installed in the groove. The protruding cylinder on the back of the tray 2 is fixed on the bearing, thereby realizing the planar rotation of the tray 2.

[0065] Example 6

[0066] The difference between this embodiment and Embodiment 5 is that: a first spherical groove is provided at the connection between the connecting seat 10 and the support plate 2. This first spherical groove can be a groove extending inward from the top of the connecting seat 10, or it can be a groove formed by the upward-protruding wall at the top of the connecting seat 10. The back of the support plate 2 has a protrusion, the top of which is a first spherical end. The support plate 2 is connected to the first spherical groove through the first spherical end, thereby realizing multi-directional rotation of the support plate 2. To simplify the assembly process, when the upward-protruding wall at the top of the connecting seat 10 forms a groove, at least one opening extending from the top to the bottom of the groove can be opened on the wall. In this way, the first spherical end on the back of the connecting seat 10 can be easily assembled into the first spherical groove. To increase the damping of the rotation of the pallet 2, an external thread can be provided on the outer side of the upward-protruding wall at the top of the connecting seat 10. Matching this is a cover with an internal thread and a protruding through hole for accommodating the connection between the back of the pallet 2 and the first spherical end. The inner wall of the cover is conical. As the cover is tightened, the upward-protruding wall at the top of the connecting seat 10 tightens inward, thereby pressing the first spherical end, increasing the friction between the first spherical groove and the first spherical end, and increasing the rotation damping of the pallet 2.

[0067] Meanwhile, the size of the opening of the first spherical groove and the diameter of the connection between the tray 2 and the first spherical end can limit the rotation angle of the tray 2. By adjusting the size of these two parts during manufacturing, the upward angle of the tray 2 is prevented from being too large, which would cause the trainer to slip off between the legs during use.

[0068] Example 7

[0069] The difference between this embodiment and embodiment four is that the multi-directional rotation of the connecting seat 10 is achieved through a spherical joint-like connection method, specifically:

[0070] The mounting groove 9 is a second spherical groove, and the connecting seat 10 is provided with a second spherical end that matches the second spherical groove. The second spherical end is inserted into the second spherical groove. The form and assembly method of the second spherical groove and the first spherical end can be referred to in Embodiment 5.

[0071] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
