Description

Technical Field

[0001] The utility model relates to the technical field of fitness and rehabilitation equipment, in particular to a torsion spring torque control structure and a pelvic floor trainer. Background Art

[0002] It is known that the pelvic floor muscles refer to the muscle group that closes the pelvic floor. The pelvic floor muscles connect the pubic bones, coccyx, etc., surround the urethra, vagina and rectal openings, support the pelvic and abdominal organs, and also work together on the bladder, intestines and sexual function. Therefore, the pelvic floor muscles are closely related to sexual function, urination function, etc. Infection, inflammation, trauma, aging, women who do not exercise in time after childbirth, and men who undergo prostate cancer surgery can all cause the pelvic floor muscles to relax. At this time, corresponding functional disorders will occur, such as incontinence, pelvic organ prolapse, etc., so there are pelvic floor muscle trainers for training and repairing pelvic floor muscles. When using it, the user can put it between the legs, and then frequently open and close the legs to frequently squeeze the splint of the pelvic floor muscle trainer and the torsion spring in the pelvic floor muscle trainer, thereby achieving the purpose of training the pelvic floor muscles.

[0003] However, the maximum angle between the two splints on the traditional pelvic floor muscle trainer is fixed. For example, the Chinese utility model patent with authorization announcement number CN217246570U discloses an adjustable pelvic floor muscle trainer, including two connecting arms hinged to each other, the two connecting arms are combined to form a V-shaped structure, and a torsion spring is provided between the two connecting arms. Since the torsion force of the torsion spring between the two connecting arms cannot be adjusted, the appropriate output force cannot be adjusted according to the needs of the user, and therefore cannot meet the use requirements.

[0034] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0035] Example 1: See Figure 1 , Figure 2 and Figure 3 A torsion spring torque control structure includes two mutually hinged connecting arms 1, wherein a torsion spring 2 is arranged inside the two mutually hinged connecting arms 1, and a force control member 3 for controlling the inner diameter movement of the torsion spring 2 to adjust the torque of the torsion spring 2 is arranged on the two mutually hinged connecting arms 1. The torque of the torsion spring 2 is adjusted by the movement of the force control member 3 on the inner diameter of the torsion spring 2.

[0036] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the force control member 3 includes a mounting seat 31 arranged on a connecting arm 1, a shaft core 32 is arranged on the mounting seat 31, a force control member 33 is arranged on the shaft core 32, one end of the shaft core 32 extends from the other connecting arm 1 and is installed with an adjustment button 34, a torsion spring 2 is arranged on the mounting seat 31, and the two ends of the torsion spring 2 are respectively located inside the two corresponding connecting arms 1, which is conducive to realizing the automatic reset of the two mutually hinged connecting arms 1 after compression. It is to be noted that the mounting seat 31 is integrally arranged on a connecting arm 1, and the mounting seat 31 is a hollow structure, and the mounting seat 31 with a hollow structure can allow the other end of the shaft core 32 to pass through, and the shaft core 32 can rotate back and forth in the mounting seat 31.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, one end of the shaft core 32 extends from the other connecting arm 1 and is equipped with an adjusting button 34, and the other end of the shaft core 32 passing through the mounting seat 31 is provided with a nut 321, and the shaft core 32 is provided with a driving part 322 for driving the force control 33, so that the shaft core 32 is rotated by rotating the adjusting button 34 back and forth, and the shaft core 32 drives the force control 33 to swim (move) back and forth along the axial direction of the shaft core 32 through the driving part 322. A cover plate 11 is provided on the outer end surface of one of the connecting arms 1, and this arrangement is reasonable. In this embodiment, the cover plate 11 and the outer end surface of the connecting arm 1 can be connected by snapping, which is convenient for disassembly and installation.

[0038] I want to explain that if Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the driving part 322 adopts an external spiral, and correspondingly, an internal thread is provided in the inner cavity of the force control unit 33. The internal thread and the external spiral cooperate with each other to enable the force control unit 33 to move back and forth along the axial direction of the shaft core 32.

[0039] I would also like to point out that if Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 8As shown, in order to prevent the force control unit 33 from moving forward with the rotation of the shaft core 32 during the adjustment process, a guide protrusion 311 is provided on the mounting seat 31, and correspondingly, a guide recess 331 is provided on the force control unit 33. The guide protrusion 311 and the guide recess 331 cooperate with each other. When the guide recess 331 and the guide protrusion 311 are engaged with each other during the movement of the force control unit 33, the force control unit 33 cannot move forward with the rotation of the shaft core 32. In this embodiment, one guide protrusion 311 is provided on the mounting seat 31, and one guide recess 331 is provided on the force control unit 33. The number of the guide protrusion 311 and the guide recess 331 can also be determined according to other actual conditions.

[0040] like Figure 1 , Figure 2 and Figure 6 As shown, the outer diameter of the force control unit 33 is less than or equal to the inner diameter of the torsion spring 2. The torsion of the torsion spring 2 is usually customized according to the wire diameter and number of turns of the torsion spring. This structure solves the problem of adjusting the torsion of the torsion spring 2 in use based on the inverse relationship between the number of turns of the torsion spring 2 and the output force. The outer diameter of the force control unit 33 is less than or equal to the inner diameter of the torsion spring 2. The force control unit 33 prevents some turns of the torsion spring 2 from contracting and releasing the torque in use. According to the inverse proportional relationship that the fewer turns of the torsion spring 2, the greater the torque, the torsion of the torsion spring 2 is increased or decreased, which is convenient for the user to use. It should be noted that the force control unit 33 uses a sleeve with an axial hole. This arrangement is reasonable and convenient for moving back and forth on the shaft core 32.

[0041] Among them, Figure 1 As shown, the adjusting button 34 is fixedly connected to one end of the shaft core 32 by a fixing member, and in this embodiment, the fixing member can be a shaft sleeve and a retaining spring, and the shaft sleeve and the retaining spring cooperate with each other to fix the adjusting button 34 on one end of the shaft core 32. Other methods can also be used for the fixing member, which is not described in detail.

[0042] Embodiment 3: It can be described on the basis of Embodiment 1 or Embodiment 2, such as Fig. 9As shown, a pelvic floor trainer includes a pad support 10, and a pad support 10 is installed on each connecting arm 1 in the above-mentioned torsion spring torque control structure. During use, the utility model rotates the adjusting button 34, so that the rotation of the adjusting button 34 drives the rotation of the shaft core 32, and the driving part 322 on the shaft core 32 drives the force control 33 to swim (move) back and forth along the axial direction of the shaft core 32. In this embodiment, when the driving part 322 drives the force control 33 to move forward along the shaft core 32 until the guide recess 331 and the guide protrusion 311 are engaged together, the force control 33 will not move forward with the rotation of the shaft core 32. Since the outer diameter of the force control 33 is less than or equal to the inner diameter of the torsion spring 2, this type of use of the torsion spring 2 torque usually customizes the wire diameter and the number of turns of the torsion spring according to the torque used. This structure is based on the torque. The inversely proportional relationship between the number of turns of the torsion spring 2 and the output force solves the problem of adjusting the torque of the torsion spring 2 during use. The outer diameter of the force control unit 33 is less than or equal to the inner diameter of the torsion spring turns. The force control unit 33 prevents part of the turns of the torsion spring from contracting and releasing torque during use in the inner diameter of the torsion spring. According to the inversely proportional relationship that the fewer the turns of the torsion spring 2, the greater the torque, the torque of the torsion spring 2 is increased or decreased. When the force control unit 33 cannot move forward with the rotation of the shaft core 32, the force control unit 33 will prevent the torsion spring from contracting. In this way, the output force (that is, the torque) of the torsion spring 2 can be adjusted according to the overlap between the force control unit 33 and the torsion spring, which is convenient for adjustment according to the actual needs of the user. When using the utility model, the output torque is adjusted by rotating the adjustment button 34. In this way, the utility model is placed between the two legs, and the inner sides of the legs are clamped on the two pads 10 respectively. The legs are clamped inwardly to make the two connecting arms 1 rotate relative to each other, and then loosen. Under the action of the torsion spring 2, the two connecting arms 1 return to their original positions. This reciprocating process can achieve the effect of exercise, and it is convenient to adjust the output force according to the actual needs of the user, which can better meet the use requirements.

[0043] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts and rivets in the prior art, which will not be described in detail here.

[0044] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described in this article, or equivalent structural or equivalent process changes made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the utility model patent.
