For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0028] As Figure 1 And Figure 2As shown, the utility model provides a kind of resistance adjustable pelvic floor muscle trainer, two connecting arms 1 and two supporting plates 2, one end of two described connecting arms 1 is connected together by torsion spring 3 as first end, oppositely, the other end of connecting arm 1 is second end, the first end 11 of two described connecting arms 1 is rotatably connected together, the second end 12 of two described connecting arms 1 is equipped with one described supporting plate 2 respectively, and torsion spring 3 is equipped at connecting place, the second end of two described first connecting arms 1 is opened to two sides under the elastic force of torsion spring 3 when the trainer is not applied external force, and it presents similar "eight" character type;When external force acts on supporting plate 2, with the continuous increase of external force, two described connecting arms 1 rotate around first end connecting place, and two supporting plates 2 are close to each other.The second end 12 of described connecting arm 1 is equipped with resistance adjustment assembly 4;
[0029] As Figure 2 Described, resistance adjustment assembly 4 includes: liftable variable diameter piece 41, knob 42 and reset spring 43, the torsion spring 3 is sleeved on the variable diameter piece 41, and the extension of the two ends of the torsion spring 3 is connected with a connecting arm 1 respectively, when two connecting arms 1 are clamped under external force, the part between the two ends of torsion spring 3 will occur elastic deformation of diameter reduction, when external force is removed, torsion spring 3 will restore original shape, at least the part of the variable diameter piece 41 that is in contact with the torsion spring 3 is tapered, which can be positive taper, or inverted taper.The one end of the variable diameter piece 41 abuts the knob 42, and the other end is connected with the reset spring 43, when the knob 42 rotates in different directions, under the cooperation of reset spring 43, the variable diameter piece 41 rises or falls.Wherein, the longitudinal section of the variable diameter piece 41 is substantially T-shaped, the vertical part is the variable diameter part, and the horizontal part is a functional table top, the bottom surface of knob 42 abuts and interacts with the functional table top.Moreover, the horizontal functional table top edge has an upwardly extending wall 412, which is in clearance fit with the connecting arm 1, and further realizes the guiding effect of wall 412 and the vertical structure in the connecting arm 1 in the lifting process of variable diameter piece 41 (see Figure 2 And Figure 5 ) Details.
[0030] When using the trainer, when it is necessary to adjust the resistance, by screwing knob 42, the variable diameter piece 41 rises or falls, and then the part of torsion spring 3 abutting with the variable diameter piece 41 is longer, that is, the part of torsion spring 3 capable of elastic deformation of diameter reduction is shorter, and then the elastic force of torsion spring 3 is larger, so that the resistance when two connecting arms 1 are clamped is larger.
[0031] In order to avoid the change of the resistance caused by the relative rotation between the knob 42 and the variable diameter piece 41 during use, the variable diameter piece 41 is provided with a limiting piece 5 in contact with the connecting arm 1, which is used to keep the variable diameter piece 41 rotating with the connecting arm 1 on which the knob is located, while not limiting the up-down movement of the variable diameter piece 41.
[0032] The pot bottom muscle trainer with adjustable resistance provided by the utility model realizes the adjustment of the length of the elastic deformation part of the torsional spring through the lifting of the variable diameter piece, realizes the adjustment of the torsional force of the torsional spring, and further makes the resistance between the two connecting arms meet the different use requirements of different users.
[0033] As shown in Figure 2 and Figure 8 , in order to avoid the relative rotation between the knob 42 and the variable diameter piece 41 during use, the further improvement of the technical scheme is that the part of the knob 42 in contact with the connecting arm 1 is provided with a convex and a recess 421 matched with each other. The convex or the recess can be circumferentially arranged. Since the reset spring 43 pushes the variable diameter piece 41 upward, the variable diameter piece 41 pushes the knob upward, so that the convex or the recess on the knob 42 can be embedded in and clamped with the recess or the convex at the corresponding position on the connecting arm 1 upwardly and downwardly. This design can avoid the relative rotation between the knob and the variable diameter piece during use, and when the resistance is adjusted, the convex can provide clear vibration feedback when sliding into and out of the recess, so that the trainer has more excellent use experience.
[0034] As shown in Figure 3 and Figure 4 , in order to fix the knob and avoid the relative rotation between the knob and the variable diameter piece during use, the further improvement of the technical scheme is that the bottom outer periphery of the knob 42 is provided with a transversely extending step piece 422, the upper surface of the step piece 422 is provided with a convex or a recess 421, and the connecting arm 1 in contact with the step piece 422 is provided with a matching structure 13 (as shown in Figure 8 ) matched with the convex or the recess 421 on the step piece 422. The matching structure 13 is: if the step piece 422 is a convex, the matching structure 13 is a recess; if the step piece 422 is a recess, the matching structure 13 is a convex. Whether it is a convex or a recess, it is multiple and circumferentially distributed.
[0035] As shown in Figures 4-7As shown, further improvement is that the lower surface of the knob 42 is provided with a first inclined surface 6 with continuously changing height, and the top surface of the variable diameter piece 41 is provided with a second inclined surface 7 matched with the first inclined surface 6, and the first inclined surface 6 and the second inclined surface 7 abut. When the knob 42 is screwed, the first inclined surface 6 and the second inclined surface 7 rotate relative to each other, and then the variable diameter piece 41 is pushed downward or moves upward under the cooperation of the reset spring 43, so as to realize the length of the abutment between the torsional spring 3 and the variable diameter piece 41, adjust the length of the elastically deformable part of the torsional spring 3, and realize the adjustment of the elastic force of the torsional spring 3.
[0036] As shown, Figures 4-7 In order to make the force applied by the knob 42 to the variable diameter piece 41 symmetrical and parallel to the central axis, and avoid the single force causing the variable diameter piece 41 to tilt, further improvement of the technical solution is that the lower surface of the knob 42 is symmetrically provided with at least two functional pieces 423 extending downward along the lower surface of the knob 42, the lower surface of the functional piece 423 is the first inclined surface 6 with continuously changing height, and the corresponding position of the functional piece 423 on the upper surface of the variable diameter piece 41 is provided with a functional groove 411, and the bottom surface in the functional groove 411 is the second inclined surface 7. Wherein, the functional piece 423 is a circular arc concentric with the knob 42, and correspondingly the functional groove 411 is also a circular arc concentric with the knob 42.
[0037] In order to avoid the variable diameter piece 41 from tilting and to move up and down more smoothly, further improvement of the technical solution is that the connecting arm 1 corresponding to the bottom end of the variable diameter piece 41 is provided with a vertical guide column 8 extending in the vertical direction, and the bottom of the variable diameter piece 41 is provided with a blind hole extending upward along the bottom end, the variable diameter piece 41 is sleeved on the guide column 8 through the blind hole, and the guide column 8 is designed to be hollow, and the reset spring 43 is placed in the guide column 8 and abuts against the inside of the guide column 8 at one end and abuts against the blind hole in the bottom of the variable diameter piece 41 at the other end, so as to provide upward elastic force for the upward reset of the variable diameter piece 41.
[0038] Further improvement is that the limiting piece 5 is a limiting protrusion, and the connecting arm 1 corresponding to the limiting protrusion is provided with a strip-shaped limiting recess extending longitudinally along the central axis of the variable diameter piece 41, and the limiting protrusion is embedded in the limiting recess, so that the connecting arm rotates and the variable diameter piece rotates at the same time.
[0039] Alternatively, the limiting piece 5 is a strip-shaped limiting groove or limiting hole extending longitudinally along the central axis of the variable diameter piece 41, and the connecting arm 1 is provided with a limiting protrusion extending into the limiting piece 5.
[0040] With the above ideal embodiment of the present application as the inspiration, through the above description, relevant staff can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and the technical scope must be determined according to the scope of claims.
