Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to a leg training device for flexible exercise. Background Art

[0002] With the improvement of people's living standards, the enthusiasm for fitness continues to rise. Various types of fitness equipment are constantly being introduced, and local fitness equipment for the buttocks, legs, pelvic floor muscles, etc. is also in great demand in the market. The pelvic floor muscles refer to the muscle group that closes the pelvic floor. This muscle group is like a "hanging net". The urethra, bladder, vagina, uterus, rectum and other internal organs are tightly suspended by this "net", thereby maintaining their normal position and performing their functions. Once the elasticity of this "net" deteriorates and the "hanging force" is insufficient, the organs in the "net" will not be able to maintain their normal position, resulting in corresponding functional disorders such as pelvic organ prolapse, urinary and fecal incontinence, hemorrhoids, etc., especially in postpartum women and older women. The phenomenon of pelvic floor muscle relaxation is more obvious.

[0003] Patent publication number CN217119251U discloses a leg clamp comprising a left bracket, a left support plate connected to a first end of the left bracket, and a right bracket connected to a first end of the right bracket. The left bracket and right bracket cavities are respectively formed at the second end of the left bracket and the second end of the right bracket. The left bracket and right bracket cavities are coupled and connected to each other by rotation about a central axis. A torque adjustment mechanism is provided within the cavities, comprising a coil spring, a coil spring mounting seat, an adjustment member, and a tooth assembly. One end of the coil spring is fixed to the coil spring mounting seat, and the other end is fixed to the adjustment member. The coil spring mounting seat is fixedly connected to the right bracket. The left bracket and the adjustment member have first and second latching positions. By changing the positions of the first and second latching positions, the winding ratio of the coil spring is changed, thereby adjusting the torque. However, this structure of the trainer has a single movement mode, which can only move the legs inward, and the trainer easily separates from the legs during exercise. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a flexible leg training device, which solves the problem that the exercise mode is single and the training device is easy to separate from the legs during exercise.

[0005] The technical solution adopted by the present invention is: a leg trainer for flexible exercise, including a first bracket and a second bracket, the second bracket is connected with a rotating cover, a torsion spring is connected between the rotating cover and the second bracket, the first bracket is provided with a ring, the ring is buckled on the rotating cover, the first bracket and the second bracket are both installed with a binding device, the ring is provided with a protrusion, the rotating cover is provided with a plurality of grooves on its circumference, or the rotating cover is provided with a protrusion, the ring is provided with a plurality of grooves on its circumference, and the protrusions are engaged with the grooves.

[0006] Through the above technical solution, when the first bracket and the rotating cover are installed, the protrusion on the ring can be inserted into any groove, and the first bracket and the second bracket form a certain angle. When the angle formed by the first bracket and the second bracket is small in the initial state, the legs can overcome the elasticity of the torsion spring and move outward to exercise the outer thigh muscle groups; when the angle formed by the first bracket and the second bracket is large in the initial state, the legs can overcome the elasticity of the torsion spring and move inward to exercise the inner thigh muscle groups; the utility model can exercise the inner and outer thigh muscle groups, and the exercise methods are more diverse; the binding device makes the connection between the trainer and the user's legs more firmly, avoiding the trainer from falling during training.

[0007] Furthermore, the number of the grooves is the same as the number of the bumps, and the grooves and the bumps are evenly distributed on the circumference.

[0008] Through the above technical solution, all the bumps are embedded in the grooves, reducing the force on each bump. The bumps are evenly distributed on the circumference so that the force on each bump is more even, and the service life of the trainer is longer.

[0009] Furthermore, the protrusion is in a strip shape and extends along the rotation axis direction of the first bracket and the second bracket.

[0010] Through the above technical solution, the contact area between the bump and the groove is increased, and the force-bearing area of ​​each bump is increased, thereby increasing the service life.

[0011] Furthermore, a clamping block is slidably connected to the second bracket, an elastic member is provided between the clamping block and the second bracket, a clamping hook is provided on the clamping block, an annular groove is provided on the first bracket, and the clamping hook is clamped on the annular groove.

[0012] Through the above technical solution, when in use, the hook is engaged with the annular groove on the first bracket to prevent the first bracket from detaching and sliding outward during movement; when the angle between the first bracket and the second bracket needs to be adjusted, press the blocks on both sides, and the hook can be disengaged from the annular groove, which facilitates the disassembly of the first bracket.

[0013] Furthermore, a first inclined surface is provided on a side of the hook close to the protrusion, and a second inclined surface is correspondingly provided on the ring.

[0014] Through the above technical solution, when installing the first bracket, the first inclined surface will slide toward the second inclined surface, causing the slider to slide inward and the elastic part to be compressed. When the first bracket is installed, the elastic part recovers, the slider slides outward, and the hook is engaged with the annular groove, making the installation process more convenient.

[0015] Furthermore, the binding device includes an arc-shaped plate, the first bracket and the second bracket are respectively connected to one of the arc-shaped plates, and a connecting belt is connected between the two ends of the arc-shaped plate.

[0016] The above technical solution can prevent the binding device from detaching from the legs during exercise, causing the trainer to fall.

[0017] Furthermore, it also includes screws, the arc-shaped plate includes a support plate and a strip plate, and the support plate and the strip plate are respectively provided with a first nut and a second nut, one of the binding devices uses the screw to selectively connect the first nut or the second nut to achieve connection with the first bracket, and the other binding device uses the screw to selectively connect the first nut or the second nut to achieve connection with the second bracket.

[0018] Through the above technical solution, when the angles of the first bracket and the second bracket are adjusted to make the legs move inward, the screw can be connected to the first nut, and the support plate is close to the inside; when the angles of the first bracket and the second bracket are adjusted to make the legs move outward, the screw can be connected to the second nut, and the support plate is close to the outside. The two movement modes make the force-bearing parts of the legs contact the support plate, making the use process more comfortable.

[0019] Furthermore, the first bracket and the second bracket are both provided with special-shaped holes, the support plate is provided with a first special-shaped block, the strip plate is provided with a second special-shaped block, and the first special-shaped block and the second special-shaped block are selectively inserted into the special-shaped holes.

[0020] Through the above technical solution, shaking of the binding device and the first bracket and the second bracket can be avoided during exercise, thereby increasing stability.

[0021] Furthermore, the number of the special-shaped holes on the first bracket is at least two, and the special-shaped holes are arranged along the length direction of the first bracket; the number of the special-shaped holes on the second bracket is at least two, and the special-shaped holes are arranged along the length direction of the second bracket.

[0022] Through the above technical solution, the positions of the first special-shaped block and the second special-shaped block and the special-shaped hole can be adjusted, thereby adjusting the distance from the first special-shaped block to the rotation axis between the first bracket and the second bracket, which saves more effort or increases resistance during exercise, making it convenient to adjust the training intensity.

[0023] Furthermore, strip-shaped holes are provided on both sides of the support plate, and one connecting belt connects two of the strip-shaped holes.

[0024] The above technical solution can prevent the trainer from sliding on the legs during exercise. BRIEF DESCRIPTION OF THE DRAWINGS
