Description

Technical Field

[0001] The utility model relates to the technical field of health care training devices, in particular to a Kegel trainer. Background Art

[0002] Kegel exercises, also known as perineum contraction exercises or pelvic floor muscle exercises, are named after Dr. Arnold Kegel of Los Angeles, USA. The purpose is to strengthen the pelvic floor muscles (or pubococcygeus muscles). These muscles stretch forward from behind the pubis and surround the vaginal orifice and rectum. Strengthening the training of the pubococcygeus muscle can improve the strength of the urethral and anal sphincters and prevent urinary incontinence and fecal incontinence.

[0003] As early as the 1940s, Dr. Kegel often recommended his patients to perform Kegel exercises to help treat stress urinary incontinence in postpartum women. Although the patients with pelvic floor muscle relaxation syndrome are mainly women, some men also suffer from this disease. Kegel exercises are applicable to both women and men and can improve the strength of the pelvic floor muscle groups of men and women.

Connecting portions 1241 can also be provided on both sides of the two support plates 124. The connecting portions 1241 are located between the support plates 124 and the inner wall of the housing, that is, the support plates 124 can be arranged between the two connecting portions 1241 to increase the support strength. The third sub - housing 121 and the fourth sub - housing 122 can be connected through these connecting portions 1241. The support plates 124 are also provided with engaging portions 1242, and the engaging portions 1242 are provided with opening and closing holes (not labeled).

[0062] The upper ends of the third sub - housing 121 and the fourth sub - housing 122 are also axially provided with at least one second mounting portion 125. The upper ends of the third sub - housing 121 and the fourth sub - housing 122 are also provided with notches 126 to expose the second mounting portion 125. Specifically, the inner walls of the upper ends of the third sub - housing 121 and the fourth sub - housing 122 are convexly provided with second mounting portions 125 on both sides, and notches 126 are provided on both sides of the upper ends of the third sub - housing 121 and the fourth sub - housing 122 to expose the second mounting portion 125. The second mounting portion 125 can be a connecting post, and a connecting hole 1251 is provided. The side wall 1261 of the notch 126 can be substantially flush with the outer peripheral edge 1252 of the connecting hole 1251 to expose as much of the link assembly 20 as possible. In other words, the side wall 1261 of the notch 126 and the outer peripheral edge 1252 of the connecting hole 1251 share a common plane.

[0063] The Kegel trainer 100 may include a plurality of link assemblies 20 which may be circumferentially spaced around the housing assembly 10. Each link assembly 20 includes a first link 21 and a second link 22 rotatably connected to the first link 21. The first link 21 is generally in a rod-like structure. The first link 21 and the second link 22 are respectively connected to the first housing 11 and the second housing 12. The first link 21 and the second link 22 are exposed by the notch 116 and the notch 126. When the link assembly 20 performs telescopic and reciprocating motions, the link portions of the first housing 11 and the second housing 12 that are exposed can simultaneously perform telescopic training and contraction training on the pelvic floor muscles.

[0064] The two ends of the first link 21 are respectively provided with a first connection portion 211 and a second connection portion 212. The second link 22 includes a third connection portion 221 and a fourth connection portion 222. The first connection portion 211 is rotatably installed in the corresponding first installation portion 115 through a push rod 23. The second connection portion 212 is rotatably connected to the third connection portion 221 through a first rotating shaft 24. The fourth connection portion 222 is rotatably installed in the corresponding second installation portion 125 through a second rotating shaft 25. At least a part of the first connection portion 211, the second connection portion 212, the third connection portion 221 and the fourth connection portion 222 are exposed from the first housing 11 and the second housing 12 by the notch 116 and the notch 126, so as to avoid the influence of the first housing 11 and the second housing 12 on the rotation of the link assembly 20.

[0065] The first connection portion 211 is axially provided with a first sliding groove 2111 along the first link 21. The second connection portion 212 is axially provided with a second sliding groove 2121 along the first link 21. The length of the first sliding groove 2111 is greater than the diameter of the push rod 23 (for example, the length of the first sliding groove 2111 is 3 - 5 times the diameter of the push rod 23). The length of the second sliding groove 2121 is greater than the diameter of the first rotating shaft 24 (for example, the length of the second sliding groove 2121 is 3 - 5 times the diameter of the first rotating shaft 24). The push rod 23 is received in the first sliding groove 2111. The two ends of the push rod 23 are respectively installed in the corresponding first installation portions 115, and the first link 21 can perform reciprocating and telescopic motions through the push rod 21. Since the length of the first sliding groove 2111 is greater than the diameter of the push rod 23 and the length of the second sliding groove 2121 is greater than the diameter of the first rotating shaft 24, when the push rod 23 drives the first link 21 to perform telescopic motion, the first link 21 can freely and smoothly perform telescopic and reciprocating motions simultaneously.

[0066] The third connecting portion 221 includes two oppositely arranged connecting arms (not labeled), and the fourth connecting portion 222 is connected below the two connecting arms. Each connecting arm is provided with a connecting hole 2211, and a connecting groove 2212 is formed between the two connecting arms. The connecting hole 2211 communicates with the connecting groove 2212. Each connecting arm is further provided with a notch 2213 communicating with the connecting hole 2211. Since the outer surface of the connecting arm is an arc surface, the connecting hole 2211 can be a straight hole, and the presence of the notch 2213 can prevent the first rotating shaft 24 from colliding with the outer surface of the connecting arm. The arc surface of the connecting arm can match the arc surfaces of the outer surfaces of the first housing 11 and the second housing 12 (such as having the same radian, etc.). The second connecting portion 212 of the first connecting rod 21 can be received in the connecting groove 2212, and the first rotating shaft 24 is movably received in the second sliding groove 2121, with both ends respectively received in the connecting holes 2211 and further extending into the notch 2213.

[0067] The outer surface of the fourth connecting portion 222 can also be an arc surface, which matches the arc surfaces of the outer surfaces of the first housing 11 and the second housing 12 (such as having the same radian, etc.). The fourth connecting portion 222 is provided with a connecting hole 2221, and the second rotating shaft 25 passes through the connecting hole 2221. Both ends of the second rotating shaft 25 are received in the corresponding second mounting portions 125, rotatably connecting the fourth connecting portion 222 to the second housing 12. The fourth connecting portion 222 can be received in the notch 126, and the third connecting portion 221 and the connecting arms together form a step 2222, and the step 2222 can be placed on the upper walls of the third sub-housing 121 and the fourth sub-housing 122, so that the third connecting portion 221 can be located between the first housing 11 and the second housing 12.

[0068] The transmission assembly 30 includes a bracket 31, a rotating member 32 received in the bracket 31 and connected to the driving assembly 40, a first sliding member 33 sleeved outside the bracket 31 and connected to the first housing 11, and a fixing member 34 disposed on the first sliding member 33. The rotating member 32 includes a guiding groove 321 that is spirally or obliquely arranged. The guiding groove 321 can be a two-way closed inclined groove or a spiral groove, and can be symmetrically arranged along the axis. The guiding groove 321 can spirally or obliquely extend from a first position (which can be a low point) on the outer surface of the rotating member 32 to a second position (which can be a high point), and then spirally or obliquely extend from the second position (which can be a high point) to the first position (which can be a low point). The fixing portion 342 of the fixing member 34 is received in the guiding groove 321. When the driving assembly 40 drives the rotating member 32 to rotate, the fixing portion 342 of the fixing member 34 interacts with the groove wall of the guiding groove 321, so that the first sliding member 33 drives the first housing 11 to perform a telescopic movement on the second housing 12 along the axis of the transmission assembly 30. Since the link assembly 20 is connected to the first housing 11 and the second housing 12, when the first housing 11 performs a telescopic movement on the second housing 12 along the axis of the transmission assembly 30, the link assembly 20 performs a reciprocating movement along the radial direction of the transmission assembly 30 while performing a telescopic movement along the axis of the transmission assembly 30.

[0069] It should be noted that the guiding groove 321 is a groove body with a high point and a low point arranged along the axis of the rotating member 32. When the first sliding member 33 slides along the guiding groove 321 under the action of the fixing member 34, the first sliding member 33 reciprocally moves along the high point and the low point of the guiding groove 321.

[0070] The bracket 31 includes a support portion 311 and a guiding portion 312.

[0071] At least one engaging portion 3112 is convexly provided on the outer wall of the supporting portion 311, and at least one engaging portion 3113 is provided at an interval from the at least one engaging portion 3112. At least one groove 413 is concavely provided on the outer wall of the driving member 41. The lower edge of the supporting portion 311 can be placed on the support plate 124. The engaging portion 3112 can be engaged in the groove 413, and the engaging portion 3113 can be engaged in the engaging hole of the engaging portion 1242, connecting the bracket 31 with the driving member 41 and the second housing 12.

[0072] A through hole 3114 communicating with the accommodating cavity 3111 is provided at the top of the guiding portion 312. The protrusion 322 at the top of the rotating member 32 is rotatably accommodated in the through hole 3114 to prevent the rotating member 32 from shaking. An accommodating hole 323 is provided in the bottom wall of the rotating member 32. The output shaft 411 of the driving member 41 can be accommodated in the accommodating hole 323. At least one fixing hole 324 is further concavely provided on the peripheral wall of the accommodating hole 323. At least one connecting protrusion 412 is convexly provided on the periphery of the output shaft 411. The connecting protrusion 412 can be accommodated in the fixing hole 324, so that the output shaft 411 can drive the rotating member 32 to rotate. In one embodiment, the cross section of the fixing hole 324 is generally in a cross-shaped structure, and of course, it can also be other structures (such as an irregular structure, a polygonal structure, etc.). The structure of the cross section of the connecting protrusion 412 matches the structure of the cross section of the accommodating hole 323. An opening 3121 is further provided in the guiding portion 312 along the axial direction. The fixing portion 342 of the fixing member 34 can pass through the opening 3121 and be accommodated in the guiding groove 321. The length of the opening 3121 can be substantially the same as the one-way stroke when the first housing 11 reciprocates.

[0073] The first sliding member 33 further includes a through hole 331, a receiving portion 332 for receiving the fixing member 34, and the second engaging portion 334. The receiving portion 332 is provided with a through hole 3321 and a mounting hole 3322. The through hole 3321 is preferably located at the lower end of the first sliding member 33. The first sliding member 33 is slidably sleeved on the bracket 31 through the through hole 331, and the shape of the inner wall of the through hole 331 matches the shape of the guiding portion 312. The fixing portion 342 of the fixing member 34 passes through the opening 312 and the through hole 3321 and is received in the guiding groove 321. The receiving portion 332 can be a groove, and the through hole 3321 and the mounting hole 3322 can be provided on the bottom wall of the groove. The fixing member 34 further includes a mounting block 341, and the fixing portion 342 protrudes from the mounting block 341. The mounting block 341 is provided with a mounting hole 3411, and a mounting member (such as a screw) can be mounted in the mounting hole 3322 and the mounting hole 3411 to fixedly connect the fixing member 34 and the first sliding member 33. The fixing portion 342 can be integrally formed with other parts of the mounting block 341 for easy installation and disassembly; it can also be formed separately and then connected integrally. The fixing portion 342 can be a metal column (such as a screw, a stud, a pin), a plastic column, a stone, or a wood, etc. The through hole 331 can be circular, polygonal, or irregular in shape, etc., and the shape of the guiding portion 312 matches the shape of the through hole 331, and can also be circular, polygonal, or irregular in shape, etc. In an embodiment, the inner wall of the through hole 331 has a plurality of straight walls and arc walls connected in pairs, and the outer wall of the guiding portion 312 also has a plurality of straight walls and arc walls connected in pairs.
