Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to a pelvic floor muscle trainer with adjustable angle. Background Art

[0002] The pelvic floor muscles are crucial for maintaining the normal physiological position and function of the pelvic organs. Pelvic floor muscle trainers have been developed to strengthen these muscles. Current pelvic floor muscle trainers consist of two hinged connecting frames with a torsion spring positioned between them. The free ends of the frames are fitted with a contact plate that fits against the legs. During training, the contact plate rests against the legs, allowing the frames to swing back and forth, clamped by the legs.

[0003] However, when using a traditional pelvic floor muscle trainer, as the legs are clamped, the angle of the fitting plate cannot be adjusted, so the contact area between the legs and the fitting plate gradually decreases, and the angle between the two continues to increase, which in turn causes the pelvic floor muscle trainer to slip. Utility Model Content

[0004] In order to solve the above problems, the utility model adopts the following technical solution: an angle-adjustable pelvic floor muscle trainer, comprising: two connecting arms and two supporting plates, wherein the first ends of the two connecting arms are rotatably connected together and a torsion spring is provided at the connection, and the second ends of the two connecting arms are respectively provided with one supporting plate;

[0005] A mounting groove is provided at the second end of the connecting arm, and the supporting plate is rotatably mounted in the mounting groove via a connecting seat provided on the back side.

[0006] A further improvement is that a platform extending from one connecting arm toward the other connecting arm is provided at the top of the connecting seat, and the support plate is installed on the platform, the center point of the connection between the platform and the support plate 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.

[0007] A further improvement is that the installation groove is a waist-shaped groove arranged along the length direction of the connecting arm, and the end of the connecting seat is arranged in the waist-shaped groove through a rotating shaft.

[0008] A further improvement is that the support plate is rotatably mounted on the connecting seat, and the support plate can be rotated in a plane around the central axis of the connecting seat.

[0009] A further improvement is that a first spherical groove is provided at the connection between the connecting seat and the supporting plate, a first spherical end is provided on the back of the supporting plate, and the supporting plate is connected to the first spherical groove through the first spherical end.

[0010] A further improvement is that the mounting groove is a second spherical groove, and the connecting seat is provided with a second spherical end matching the second spherical groove, and the second spherical end is inserted into the second spherical groove.

[0011] The beneficial effects of the utility model are:

[0012] The utility model provides an angle-adjustable pelvic floor muscle trainer, in which the support plate is rotatably mounted on the mounting groove via a connecting seat on the back, so that the angle of the support plate can be moved with the user during use, so that the support plate always fits completely with the legs to avoid slipping; at the same time, the opening size of the mounting groove can limit the rotation angle of the connecting seat, thereby playing a limiting role, avoiding the support plate from rotating upward at an excessively large angle, which may cause the trainer to slip.

[0021] It should be noted that Figure 1-3 These are all structural schematic diagrams of the pelvic floor muscle trainer in a clamped state.

[0022] Example 1

[0023] like Figures 1 to 3 As shown, the utility model provides an angle-adjustable pelvic floor muscle trainer, comprising: two connecting arms 1 and two supporting plates 2, wherein one end of the two connecting arms 1 connected together by a torsion spring is a first end, and relatively speaking, the other end of the connecting arm 1 is a second end, the first ends 11 of the two connecting arms 1 are rotatably connected together, the second ends 12 of the two connecting arms 1 are respectively provided with a supporting plate 2, and a torsion spring is provided at the connection. When no external force is applied to the trainer, under the elastic force of the torsion spring, the second ends of the two first connecting arms 1 open to both sides, presenting an "eight" shape; when an external force acts on the supporting plate 2, as the external force continues to increase, the two connecting arms 1 rotate around the connection at the first end, and the two supporting plates 2 approach each other.

[0024] In order to enable the rotation angle of the support plate 2 to follow the user's use, in the present technical solution, a mounting groove 3 is provided at the second end 12 of the connecting arm 1. The opening direction of the mounting groove 3 is perpendicular to the length extension direction of the connecting arm 1, and is located on the outside of the rotation direction of the connecting arm 1. The support plate 2 is rotatably installed in the mounting groove 3 through the connecting seat 4 connected on the back, and its rotation direction can be a plane rotation 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 4 and the mounting groove 3, thereby realizing multi-directional following of the support plate 2.

[0025] The utility model provides an angle-adjustable pelvic floor muscle trainer, in which the support plate is rotatably mounted on the mounting groove via a connecting seat on the back, so that the angle of the support plate can be moved with the user during use, so that the support plate always fits completely with the legs to avoid slipping; at the same time, the opening size of the mounting groove can limit the rotation angle of the connecting seat, thereby playing a limiting role, avoiding the support plate from rotating upward at an excessively large angle, which may cause the trainer to slip.

[0026] Example 2

[0027] If the directions of the forces acting on the two support plates 2 are not in the same plane when the pelvic floor muscle trainer is in use, it is easy for the trainer to rotate around the central axis during use, thereby causing the trainer to slip. This problem has not been solved, and the further improvement of the technical solution is as follows: an angle-adjustable pelvic floor muscle trainer, 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 connected together by rotation, 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. When no external force is applied to the trainer, 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 acts on the support plates 2, as the external force continues to increase, the two connecting arms 1 rotate around the connection at the first end, and the two support plates 2 approach each other.

[0028] In order to enable the rotation angle of the support plate 2 to follow the user's use, in the present technical solution, a mounting groove 3 is provided at the second end 12 of the connecting arm 1. The opening direction of the mounting groove 3 is perpendicular to the length extension direction of the connecting arm 1, and is located on the outside of the rotation direction of the connecting arm 1. The support plate 2 is rotatably installed in the mounting groove 3 through the connecting seat 4 connected on the back, and its rotation direction can be a plane rotation 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 4 and the mounting groove 3, thereby realizing multi-directional following of the support plate 2.

[0029] like Figure 2 and Figure 3The top of the connecting seat 4 is provided with a platform 5 extending from one connecting arm 1 toward the other connecting arm 1, and the back of the support plate 2 is fixedly or movably mounted on the platform 5. When the support plate 2 and the platform 5 are fixedly connected, the support plate 2, the platform 5, and the connecting seat 4 can be integrally formed. The center point of the connection between the platform 5 and the support plate 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. In this way, during use, the forces acting on the two support plates 2 are on the same plane, so no axial rotation occurs.

[0030] At the same time, since the platform 5 extends toward the direction of the connecting arm 1, and the center point of the connection between the platform 5 and the support plate 2 is located in the middle position of the two connecting arms 1, the outer edge of the platform 5 in the direction toward the connecting arm 1 will inevitably exceed the middle position of the two connecting arms 1 and cover part of the opposite connecting arm 1, thereby achieving 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, thereby avoiding the connecting arm 1 from rotating too much and hitting the back of the opposite support plate 2, causing damage to the connection of the support plate 2 connecting seat 4.

[0031] Example 3

[0032] like Figure 1 and Figure 2 The utility model shown provides an angle-adjustable pelvic floor muscle trainer, comprising: two connecting arms 1 and two supporting plates 2, wherein one end of the two connecting arms 1 connected together by a torsion spring is a first end, and relatively speaking, the other end of the connecting arm 1 is a second end, the first ends 11 of the two connecting arms 1 are rotatably connected together, the second ends 12 of the two connecting arms 1 are respectively provided with a supporting plate 2, and a torsion spring is provided at the connection. When no external force is applied to the trainer, under the action of the elastic force of the torsion spring, the second ends of the two first connecting arms 1 open to both sides, presenting an "eight" shape; when an external force acts on the supporting plate 2, as the external force continues to increase, the two connecting arms 1 rotate around the connection at the first end, and the two supporting plates 2 approach each other.

[0033] In order to enable the rotation angle of the support plate 2 to follow the user's use, in the present technical solution, a mounting groove 3 is provided at the second end 12 of the connecting arm 1. The opening direction of the mounting groove 3 is perpendicular to the length extension direction of the connecting arm 1, and is located on the outside of the rotation direction of the connecting arm 1. The support plate 2 is rotatably installed in the mounting groove 3 through the connecting seat 4 connected on the back, and its rotation direction can be a plane rotation 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 4 and the mounting groove 3, thereby realizing multi-directional following of the support plate 2.

[0034] A further improvement is that the mounting groove 3 is a waist-shaped groove arranged along the length direction of the connecting arm 1, and a rotating shaft perpendicular to the rotation plane of the connecting arm 1 is installed in the waist-shaped groove. If the rotating shaft is fixedly installed in the waist-shaped groove, a through hole is opened at the end of the connecting seat 4, and the rotating shaft passes through the through hole, so that the connecting seat 4 can rotate around the rotating shaft. At the same time, by adjusting the size of the gap between the waist-shaped groove and the connecting seat 4 during manufacturing, the swing angle of the connecting seat 4 can be limited. The distance between the rotating shaft and the end of the waist-shaped groove is adjusted as needed during manufacturing, and the swing angle range of the connecting seat 4 can also be adjusted.

[0035] In another embodiment, the rotating shaft is fixedly mounted at the bottom end of the connecting seat 4, 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 the 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 mounted on the bearings, thereby realizing the free rotation of the rotating shaft.

[0036] Example 4

[0037] In order to adapt to the different use angles of the training device, this embodiment is a further improvement on the basis of the third embodiment in that the support plate 2 is rotatably mounted on the connecting seat 4 and the support plate 2 can be rotated in a plane around the central axis of the connecting seat 4. Therefore, when the training device is in use, the connecting arm can be in the same direction as the thigh or in a different direction. The rotation of the support plate 2 can be achieved in the following two ways:

[0038] The first method is to have a raised cylinder on the back of the support plate 2, with the top of the cylinder connected to the disc. The connecting seat 4 is provided with a groove, and the opening of the groove is designed to be closed, that is, the groove is just stuck on the cylinder, and the groove is closed to enclose the disc in the groove, so that the disc will not fall out of the groove and can still rotate freely.

[0039] The second type: a raised cylinder is provided on the back of the support plate 2, a groove is provided on the connecting seat 4, and a bearing is fixed in the groove, and the raised cylinder on the back of the support plate 2 is fixed on the bearing, thereby realizing the planar rotation of the tray 2.

[0040] Example 5

[0041] The difference between this embodiment and the fourth embodiment is that a first spherical groove is provided at the connection between the connecting seat 4 and the supporting plate 2. The first spherical groove can be a groove extending inwardly from the top of the connecting seat 4, or a groove formed by the upwardly protruding wall at the top of the connecting seat 4. The back of the supporting plate 2 is provided with a protrusion, the top of which is a first spherical end. The supporting plate 2 is connected to the first spherical groove via the first spherical end, thereby achieving multi-directional rotation of the supporting plate 2. To simplify the assembly process, when the upwardly protruding wall at the top of the connecting seat 4 forms a groove, at least one opening extending from the top to the bottom of the groove can be provided on the wall. In this way, the first spherical end on the back of the connecting seat 4 can be easily assembled into the first spherical groove. In order to increase the damping of the rotation of the support plate 2, an external thread can be set on the outside of the upwardly protruding wall at the top of the connecting seat 4, and a cover with an internal thread and a raised through hole for accommodating the back side of the support plate 2 and connecting it with the first spherical end is matched therewith. The inner wall of the cover is conical. As the cover is tightened, the upwardly protruding wall at the top of the connecting seat 4 is tightened inward, thereby pressing the first spherical end, thereby increasing the friction between the first spherical groove and the first spherical end, and increasing the rotation damping of the support plate 2.

[0042] At the same time, the size of the opening of the first spherical groove and the diameter of the connection between the support plate 2 and the first spherical end can limit the rotation angle of the support plate 2. By adjusting the sizes of these two points during manufacturing, it is possible to prevent the support plate 2 from rising too much, causing the trainer to slip between the legs during use.

[0043] Example 6

[0044] The difference between this embodiment and the third embodiment is that the multi-directional rotation of the connecting seat 4 is achieved by a spherical joint connection method, specifically:

[0045] The mounting groove 3 is a second spherical groove, and the connecting seat 4 is provided with a second spherical end that matches the second spherical groove, and 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 refer to the fifth embodiment.

[0046] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
