[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 6 The utility model provides a technical solution: a waist trainer with adjustable strength, comprising a base 1, an L-shaped bracket 12 is installed on the top of the base 1, a mounting seat 18 is horizontally installed on the top of the L-shaped bracket 12, a support rod 13 is coaxially rotated in the mounting seat 18, the top of the support rod 13 is connected to the seat plate 11, the seat plate 11 is horizontal and has a seat cushion 10 on the surface, after the human body sits on the seat cushion 10, the human body can rotate around the support rod 13 on the seat plate 11, in order to make the L-shaped bracket 12 better supporting, at least one reinforcement frame 14 is provided on the side of the L-shaped bracket 12, the reinforcement frame 14 and the base 1 and the L-shaped bracket 12 form a triangular support structure;

[0030] like Figure 1 and Figure 2As shown, in the actual use process, the problem of foot placement of the human body after sitting on the seat 11 must also be considered, so the bottom of the support rod 13 is designed to be a structure extending horizontally toward the armrest 5, and footrests 2 are provided on both sides of the end of the support rod. When the human body sits on the seat 11, the feet can be placed on the footrests 2. During the rotation process, the bottom of the support rod 13 does not contact the reinforcement frame 14 to avoid contact between the two.

[0031] An armrest 5 is provided on the top of the base 1 and is located on one side of the seat 11. The armrest 5 includes a support frame 3 vertically mounted on the base 1. The top of the support frame 3 extends above the seat 11. The top of the support frame 3 is connected to the middle of the horizontal frame 4.

[0032] Both ends of the horizontal frame 4 are connected to L-shaped arms 6 extending in the opposite direction of the seat plate 11 , and handles 7 are provided at the ends of the L-shaped arms 6 .

[0033] like Figure 2 and Figure 3 As shown, a stopper 9 is provided at the middle of the top of the seat 11 near the armrest 5. It is very necessary to provide the stopper. When a person sits on the seat 11, the legs can be clamped on the side of the stopper 9, so that when the hands of the person grab the handle 7, the legs can clamp the stopper 9 to exert force.

[0034] A friction wheel 15 is coaxially provided on the outside of the side of the mounting seat 18, and a friction plate is provided on one side of the friction wheel 15. The bottom of the stopper 9 extends below the seat plate 11 and a screw progressive mechanism 16 is provided at the bottom thereof. Figure 5 and Figure 6 As shown, the screw advancement mechanism 16 includes an annular support 25 located on one side of the friction wheel 15. The top of the annular support 25 is connected to the bottom of the stopper 9 through a fixing frame 19, so that the annular support 25 is fixed below the stopper 9. An adjustment shaft 31 is slidably provided in the annular support 25, so that the adjustment shaft 31 can be extended and retracted in the annular support 25. In actual use, the adjustment shaft 31 is radially arranged with respect to the friction wheel 15, and the friction plate is installed at the end of the adjustment shaft 31 close to the friction wheel 15, so that the adjustment shaft 31 can drive the friction plate to advance in the opposite direction toward the friction wheel 15.

[0035] The end of the adjusting shaft 31 away from the friction wheel is located in the annular fixed seat 30. The end of the adjusting shaft 31 away from the friction wheel is provided with an external thread, and the annular fixed seat 30 is provided with an internal thread, so that the adjusting shaft 31 and the annular fixed seat 30 are threadedly connected. The end of the annular fixed seat 30 close to the friction wheel is coaxially provided with an annular bearing seat 23. The annular bearing seat 23 is rotatably mounted on the annular bearing support 24. The annular bearing seat 23 and the annular bearing support 24 are specifically connected through a bearing. The adjusting shaft 31 is placed in the annular bearing support 24, and the end of the annular bearing support 24 is coaxially connected to the side of the annular support 25.

[0036] A second bevel gear 22 is coaxially mounted on one end of the annular fixing seat 30 away from the friction wheel. The top of the second bevel gear 22 is meshed with the first bevel gear 21. The first bevel gear 21 is coaxially arranged below the rotating shaft 20. The rotating shaft 20 is located in the block seat 9, and the top of the rotating shaft 20 extends outside the top of the block seat 9. The rotating shaft 20 is rotatably connected to the block seat 9. A knob 8 is provided on the top of the rotating shaft 20.

[0037] Specifically, a guide shaft 29 parallel to the adjustment shaft 31 is provided on the mounting plate 27. The guide shaft 29 extends toward the rotating shaft 20. The guide shaft 29 is slidably placed in the connecting seat 28. The connecting seat 28 is mounted on the annular support 25.

[0038] When the knob 8 is turned, it drives the rotating shaft 20 to rotate, and the rotating shaft 20 drives the annular fixing seat 30 to rotate through the engagement of the first bevel gear 21 and the second bevel gear 22. Since the annular fixing seat 30 is threadedly connected to the adjusting shaft 31, the rotation of the annular fixing seat 30 can drive the adjusting shaft 31 to extend and retract in the annular support 25, thereby driving the friction plate to contact the friction wheel 15. That is, by turning the knob 8, the force between the friction plate and the friction wheel 15 can be adjusted, thereby changing the rotation force of the friction wheel 15.

[0039] The present application also improves the friction plate, such as Figure 5 and Figure 6 As shown, the friction plate includes a mounting plate 27 mounted on the end of the adjusting shaft 31. The mounting plate 27 is removably provided with a pressure plate 26 with an arc-shaped side on one side close to the friction wheel. A friction skin is provided inside the pressure plate 26. The mounting plate 27 and the arc-shaped pressure plate 26 are fastened by bolts. In this way, when the friction skin is worn to a preset value, the pressure plate can be removed and then replaced with a new friction skin.

[0040] Furthermore, in order to prevent the screw advancement mechanism 16 from coming into contact with people when rotating, a housing 17 is provided below the stopper 9 , and the housing 17 covers the screw advancement mechanism 16 therein.

[0041] To sum up, the operation process of the utility model is that the user can sit on the seat 11, then place his legs on both sides of the block seat 9, put his feet on the foot pedal 2, hold the handle 7 with both hands, and then clamp the block seat 9 with his legs, so that the waist can exert force to drive the seat 11 to rotate; after the user stops the seat 11, he can turn the knob 8 by hand. The knob 8 is set in front of the user for easy use, and the pressure between the friction skin and the friction wheel 15 can be adjusted by turning the knob 8, thereby changing the force of the friction wheel 15 when rotating left and right.
