Description

Technical Field

[0001] The present application relates to the technical field of fitness equipment, and in particular to a pelvic floor muscle trainer. Background Art

[0002] The pelvic floor muscles are the muscles that seal the pelvic floor. These muscles are involved in the urethra, bladder, vagina, uterus, rectum, and other organs. Loss of elasticity in these muscles can cause these organs to lose their normal position, leading to functional impairments such as pelvic organ prolapse, incontinence, and hemorrhoids. Pelvic floor muscle relaxation is particularly pronounced in postpartum women and older women. For this reason, people generally use pelvic floor muscle trainers to train their pelvic floor muscles, improving their elasticity and preventing them from becoming lax.

[0003] The pelvic floor muscle training device of the related art is also called a leg beautifying device, a buttock beautifying device or a buttock beautifying device, etc. Its structure generally includes a first lever arm, a second lever arm and a rotating shaft. The first lever arm and the second lever arm are provided with matching rotating connecting parts, which are connected by the rotating shaft so that the first lever arm and the second lever arm can rotate around the rotating shaft; a torsion spring is connected to the rotating shaft, one end of the torsion spring is connected to the first lever arm, and the other end of the torsion spring is connected to the second lever arm. The torsion spring provides a restoring force for the rotation of the first lever arm and the second lever arm, as well as an elastic force between the first lever arm and the second lever arm; The outer ends of the first and second lever arms are each equipped with a support portion or cushion that contacts the leg muscles. During use, the pelvic floor muscle trainer is placed between the legs, with the support portions of the first and second lever arms respectively contacting the inner leg muscles. The legs simultaneously clamp the first and second lever arms inward, thereby strengthening the pelvic floor muscles. For example, the pelvic floor muscle training devices disclosed in patent applications with publication numbers CN214260482U, CN217139121U, and CN218220972U. Another example is the pelvic floor muscle training devices disclosed in patent applications with publication numbers CN117815617A and CN216725673U. The resistance of the two arms to the leg clamping action can be adjusted by adjusting the compression of the spring, thereby making the resistance of the pelvic floor muscle training device adjustable to meet the needs of different people.

[0004] The pelvic floor muscle trainers of the above-mentioned related technologies generally have the following defects: First, the pelvic floor muscle trainer in which a torsion spring is arranged between the two force arms uses the elastic force of the torsion spring to make the two force arms provide resistance to the leg clamping action, but the resistance of the torsion spring is not adjustable, and cannot meet the resistance requirements of the pelvic floor muscle trainer for different training stages or different groups of people; Second, the pelvic floor muscle trainer in the related technology uses the compression amount of the spring to adjust the resistance of the two support arms to the leg clamping action. It has many internal parts, a relatively complex structure, troublesome assembly, and a high production cost. Utility Model Content

[0025] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of the present application and are not intended to limit the scope of protection of the embodiments of the present application. Those skilled in the art may adjust them as needed to suit specific application scenarios.

[0026] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.

[0027] In the embodiments of the present application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, a first feature being "above," "above," and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] See also Figures 1 to 5As shown; the embodiment of the present application discloses a pelvic floor muscle trainer, also known as a leg beautifying device, a buttock beautifying device, etc., whose structure includes a trainer body, the trainer body includes an elastic component 4 and two hollow lever arms: a first lever 1 and a second lever 2, the first lever 1 and the second lever 2 are arranged to be relatively inclined, and the first end of the first lever 1 is rotatably connected to the first end of the second lever 2, specifically, the first end of the first lever 1 is provided with a first connecting portion 100, the first end of the second lever 2 is provided with a second connecting portion 200 adapted to the first connecting portion 100, and the first connecting portion 100 and the second connecting portion 200 are rotatably connected through a rotating shaft 6, the second end of the first lever 1 and the second end of the second lever 2 are respectively connected to a cushion 3 that is against the leg muscles; the cushion 3 is respectively connected to the outside of the second end of the first lever 1 and the outside of the second end of the second lever 2, and the surface of the cushion 3 is set to be an arc surface adapted to the human leg muscles. When the pelvic floor muscle trainer is used, it is placed between the two legs, and the cushions 3 at the second ends of the first lever 1 and the second lever 2 are respectively against the inner sides of the legs.

[0030] Further in this embodiment, see Figure 4 and Figure 5 As shown, the elastic component 4 of the training device body is arranged in the two force arms. Specifically, the elastic component 4 includes a cable 400 and an elastic member 401. The cable 400 is a flexible cable 400, and the elastic member 401 is a columnar coil spring. The first end of the cable 400 is connected to the first force arm 1, and the second end of the cable 400 is connected to the first end of the elastic member 401 after passing through the rotating connection part of the two force arms, and the second end of the elastic member 401 is connected to the second force arm 2; the cable 400 and the elastic member 401 are in series relationship, and the cable 400 is always in a tensioned or taut state; when the two force arms are driven to perform repeated clamping actions, the cable 400 drives the elastic member 401 to stretch or reset axially, and the elastic member 401 provides resistance to the clamping action of the two arms to the legs. It has a simple structure, low production cost and is easy to install.

[0031] For example, Figure 4 and Figure 5 As shown, the first end of the cable 400 is connected to the limiting block 402, and the limiting block 402 is axially limited or fixedly connected to the end of the second end of the first lever 1. The second end of the cable 400 passes over the top of the rotating shaft 6 and is fixedly connected downward to the first end of the elastic member 401 in the second lever 2, and the second end of the elastic member 401 is connected to the second lever 2.

[0032] In order to make the resistance of the pelvic floor muscle trainer adjustable, the pelvic floor muscle trainer is further provided with an adjustment component 5, such as Figure 2 and Figure 4As shown, the adjustment assembly 5 is connected to the first lever 1 or the second lever 2, and is also connected to the cable 400 or the elastic member 401. The adjustment assembly 5 adjusts the resistance generated by the elastic member 401 when clamping the two lever arms by adjusting the stretched length of the elastic member 401. The adjustment assembly 5 makes the resistance of the pelvic floor muscle trainer adjustable, which can meet the resistance requirements of different groups of people at different training stages. Alternatively, during pelvic floor muscle training, the resistance of the pelvic floor muscle trainer can be gradually increased or decreased to achieve better training results.

[0033] Specifically in this embodiment, Figure 4 and Figure 5 As shown, the adjustment assembly 5 is connected to the second lever arm 2, and the adjustment assembly 5 includes a threaded rod 500 rotatably connected to the second lever arm 2 and an adjustment knob 501 arranged outside the second lever arm 2 and connected to the threaded rod 500. An adjustment block 502 is threadedly connected to the threaded rod 500, and the adjustment block 502 is connected to the second end of the elastic member 401. When the adjustment knob 501 is rotated, the adjustment block 502 moves along the axial direction of the threaded rod 500 and stretches or releases the elastic member 401. When the adjusting knob 501 is rotated to cause the adjusting block 502 to move along the axial direction of the threaded rod 500 toward the adjusting knob 501, the adjusting block 502 pulls the second end of the elastic member 401, causing the elastic member 401 to stretch a certain length. At this time, the resistance of the elastic member 401 to the two force arms increases; conversely, when the adjusting knob 501 is rotated to cause the adjusting block 502 to move along the axial direction of the threaded rod 500 toward the direction away from the adjusting knob 501 or toward the elastic member 401, the elastic member 401 contracts and resets. At this time, the resistance of the elastic member 401 to the two force arms decreases.

[0034] For example, the adjustment component 5 is rotatably connected to the second lever arm 2, specifically, as Figure 4 As shown, the threaded rod 500 of the adjustment assembly 5 is provided with an annular limiting groove 503 along the circumference, and a clamp 504 is connected to the second lever 2 to limit the axial movement of the threaded rod 500, and the clamp 504 is engaged in the annular limiting groove 503. The clamp 504 is also known as a retaining spring, which is engaged in the annular limiting groove 503 of the threaded rod 500, limiting the axial movement of the threaded rod 500 and allowing the threaded rod 500 of the adjustment assembly 5 to rotate circumferentially.

[0035] In this embodiment, if Figure 5 As shown, a slide groove 201 extending axially along the threaded rod 500 is provided in the second arm 2, and the adjustment block 502 is slidably connected in the slide groove 201. This arrangement allows the adjustment block 502 to move more smoothly and steadily when the traction elastic member 401 is stretched.

[0036] In some embodiments, as Figure 3As shown, the second ends of the first and second lever arms 1 and 2 are both tilted toward the center of the pelvic floor muscle trainer. This arrangement not only makes the structure between the two lever arms more compact and reduces the guaranteed volume of the product, but also allows the force of the two lever arms to be concentrated at the center of the pelvic floor muscle trainer during the clamping action, reducing or eliminating the lateral force between the two lever arms and ensuring the service life of the pelvic floor muscle trainer. The lateral force between the two lever arms refers to the pulling force that moves the two lever arms away from each other along the axis of the rotating shaft 6.

[0037] In some embodiments, to facilitate assembly between the elastic assembly 4 and the lever arm, a first cover plate 101 is connected to the first lever arm 1. Opening the first cover plate 101 opens the inner cavity of the first lever arm 1. In addition, a second cover plate 202 is connected to the second lever arm 2. Opening the second cover plate 202 opens the inner cavity of the second lever arm 2. This arrangement facilitates assembly and maintenance.

[0038] In other embodiments, the adjustment assembly 5 can also be a cam wrench rotatably connected to the second force arm 2, and the cam portion of the cam wrench is connected to the second end of the elastic member. The cam wrench can be rotated to a first state and a second state. In the first state, the cam portion of the cam wrench stretches the elastic member outward, and in the second state, the cam portion of the cam wrench compresses or releases the elastic member inward, thereby switching the elastic member between the two stretching lengths to achieve adjustment of the resistance between the two force arms.

[0039] In some embodiments, an adjustment assembly 5 can also be connected to the first lever arm 1, and the adjustment assembly 5 includes a threaded rod rotatably connected to the first lever arm 1 and an adjustment knob disposed outside the first lever arm and connected to the threaded rod. An adjustment block is threadedly connected to the threaded rod, and the adjustment block is connected to the first end of the cable. When the adjustment knob is rotated, the adjustment block moves axially along the threaded rod and stretches or releases the elastic member via the cable. In this embodiment, the adjustment assembly is rotatably connected to the first lever arm 1 and connected to the cable. In this way, the tension length of the elastic member can be adjusted via the cable, thereby adjusting the resistance between the two lever arms.

[0040] In the description of the embodiments of the present application, it should be noted that in the description of the present application, terms such as "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation.
