[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 An adjustable waist twisting machine includes a base frame 1 and a pedal frame 2. Pedals 3 are symmetrically arranged on the pedal frame 2. A rotating support 4 is located at the center of the base frame 1, and the pedal frame 2 rotates to engage with the rotating support 4 of the base frame. An elastic return assembly 5 is provided between the base frame 1 and the pedal frame 2. The base frame 1 has several lower adjustment holes 6, and the bottom of the pedal frame 2 on the opposite side of the pedal 3 has several upper adjustment holes 7. The elastic return assembly 5 includes an elastic rope 51 and locking bolts 52 that engage at both ends of the elastic rope 51. The locking bolts 52 at both ends are respectively fixed to the upper adjustment holes 7 and the lower adjustment holes 7. Within the adjustment hole 6, the two ends of the elastic rope 51 are fixed and limited within different upper and lower adjustment holes 7 and 6, thereby adjusting the resistance by adjusting the range of motion. The further away from the center of the rotating support, the greater the twisting force required for the same range of motion, and vice versa. The elastic rope 51 is generally set at intervals of 2 adjustment holes for optimal elasticity recovery. At the same time, the elasticity recovery component 5 is set at the gap between the base frame 1 and the pedal frame 2 and transitioned through the locking bolt 52, which can also effectively avoid noise caused by friction between the pedal frame 2 and the elastic component, resulting in an excellent user experience.

[0022] The upper adjustment hole 7 and the lower adjustment hole 6 are offset from each other. The distance between the upper adjustment hole 6 and the rotating support 4 is greater than the distance between the lower adjustment hole 6 and the rotating support 4. The back of the upper adjustment hole 7 is the pedal 3. The outer end of the elastic rope 51 is fixed to the upper adjustment hole 7, which makes the waist twisting effect better.

[0023] Both the upper adjustment hole 7 and the lower adjustment hole 6 are fitted with fastening seats 8 for fixing the locking bolt 52. The upper end of the locking bolt 52 has a groove for engaging the two ends of the elastic rope. The fastening seat 8 is used to fix the locking bolt 52 to prevent it from directly contacting the adjustment hole and causing friction, thus reducing noise. A silent sleeve 521 is provided on the locking bolt 52 for the elastic rope 51 to be sleeved on. The silent sleeve 521 prevents it from directly contacting the elastic rope and causing friction, thus reducing noise.

[0024] The elastic rope 51 is provided with limit sleeves 9 at both ends, which ensure that the elastic rope 51 is stably fitted on the locking bolt 52.

[0025] The pedal frame 2 is provided with a sleeve 10 that mates with the rotating support 4. The sleeve 10 has an upper bearing 11 and a lower bearing 12 at both ends. The sleeve 10 is also equipped with a knob 21 that is rotatably connected to the rotating support 4. The double bearings of the upper bearing 11 and the lower bearing 12 at both ends of the pedal frame 2 ensure the smoothness of the twisting rotation. The knob 21 can realize the assembly and disassembly of the pedal frame 2 on the base frame 1.

[0026] A detachable upright connecting frame 13 is provided on one side of the center of the base frame 1. The upright connecting frame 13 is also fitted with a lower upright 14 and an upper upright 15. The upper upright 15 is detachably sleeved inside the lower upright 14. A handrail frame 16 is also detachably provided on the upper upright 15. The upright connecting frame 13 is used to connect the lifting upright and the handrail to further improve stability and adaptability.

[0027] The base frame 1 is equipped with anti-slip and noise-reducing sleeves 17 around its perimeter. The anti-slip and noise-reducing sleeves 17 not only prevent slipping but also reduce noise.

[0028] The pedal 3 is evenly provided with several massage protrusions 18, which are distributed in a fan shape, so as to realize the foot massage function while twisting the waist.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
