Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] As Figures 1 to 4 shown, this embodiment provides a new type of waist twister, including:

[0039] A chassis 1, on which a swing arm 2 is rotatably provided, and pedals 3 are provided at both ends of the swing arm 2;

[0040] A reset device, when the swing arm 2 rotates relative to the chassis 1 under an external force and when the external force is withdrawn, the reset device is used to return the swing arm 2 to the position when no external force is applied;

[0041] A seat plate 4, rotatably arranged on the upper side of the swing arm 2; and,

[0042] A locking component, which is used to lock the swing arm 2 and the chassis 1.

[0043] In this embodiment, the waist twister includes a standing waist-twisting mode and a sitting waist-twisting mode. In the standing waist-twisting mode, the user steps on the pedals 3 with both feet and rotates the swing arm 2 relative to the chassis 1 through the strength of the waist and abdomen. In the sitting waist-twisting mode, the user's feet support on the ground and the buttocks sit on the seat plate 4. The function of the locking component is to prevent the swing arm 2 from rotating and hitting the legs in the sitting waist-twisting mode, thereby locking the swing arm 2 and the chassis 1.

[0044] To accommodate people with different heights and leg lengths, in this embodiment, an adjustment component is provided between the seat plate 4 and the swing arm 2, and the adjustment component is used to adjust the height of the seat plate 4 relative to the ground. Specifically, the seat plate 4 can be rotatably connected to the swing arm 2 through a rotating shaft, and the rotating shaft can be set as a telescopic type and can be adjusted and fixed at the adjusted length. To achieve a better fitness effect, a torsion spring can be provided between the seat plate 4 and the swing arm 2.

[0045] Among them, to facilitate switching between the two modes and for the user to step on the two pedals 3 with both feet respectively in the standing and twisting mode, the seat plate 4 can be set to be detachably connected to the swing arm 2. In this embodiment, the shape of the seat plate 4 can be set as a round cake shape or the like.

[0046] Among them, since the middle part of the swing arm 2 is rotatably connected to the chassis 1, the locking component can be set as a group and is arranged between one end of the swing arm 2 and the chassis 1;

[0047] Or, to achieve a better effect and prevent the swing arm 2 from swinging relative to the chassis 1, the locking component can also be set as two groups, and the two groups of locking components are respectively arranged between the two ends of the swing arm 2 and the chassis 1.

[0048] To facilitate switching between the two modes, the locking component is preferably a structure that is easy to disassemble. As a specific implementation manner, the locking component includes a bolt 21, a first through hole 22 provided at the end of the swing arm 2, and a second through hole 111 provided on the chassis 1. The bolt 21 locks the swing arm 2 and the chassis 1 by being inserted into the first through hole 22 and the second through hole 111. When it is necessary to switch to the standing and twisting mode, just toggle the bolt 21 to unlock the first through hole 22 and the second through hole 111.

[0049] Such as Figure 3As shown, the specific structure can also be set such that the bolt 21 is slidably disposed in the first through hole 22. The bolt 21 includes a locking position inserted in the first through hole 22 and the second through hole 111 and an unlocking position disengaged from the second through hole 111, thereby preventing the bolt 21 from falling and being lost. To facilitate user operation and improve safety, a locking portion 211 is provided on the bolt 21. On the side wall of the first through hole 22, there is a first positioning groove 221 that cooperates with the locking portion 211 to keep the bolt 21 in the locking position and a second positioning groove 222 that cooperates with the locking portion 211 to keep the bolt 21 in the unlocking position. Between the first positioning groove 221 and the second positioning groove 222, there is a guiding groove 223 for the locking portion 211 to switch between the first positioning groove 221 and the second positioning groove 222. The structures of the first positioning groove 221, the second positioning groove 222, and the guiding groove 223 can refer to the structure of a bolt-type door lock. In the standing and twisting mode, the locking portion 211 cooperates with the second positioning groove 222 to keep the bolt 21 in the unlocking position, and when the user drives the swing arm 2 to rotate reciprocally, the displacement of the bolt 21 can be avoided. In the sitting and twisting mode, the locking portion 211 cooperates with the first positioning groove 221 to keep the bolt 21 in the locking position, so that the swing arm 2 is locked to the chassis 1, preventing the swing arm 2 from being rotated by an external force and hitting the leg.

[0050] A bracket 11 is provided on the chassis 1. The bracket 11 is located outside the end of the swing arm 2. The second through hole 111 is provided on the bracket 11. The bolt 21 locks the swing arm 2 in the position when no external force is applied by being inserted into the first through hole 22 and the second through hole 111. When it is necessary to lock the swing arm 2 to the chassis 1, first align the first through hole 22 and the second through hole 111 coaxially, and then insert the bolt 21 into the second through hole 111.

[0051] Among them, the position of the locking assembly can also be set between the pedal 3 and the chassis 1, and the structure of the locking assembly can also be set to other structures that can achieve its functions.

[0052] In this embodiment, to facilitate the user to sit on the seat plate 4, the seat plate 4 is preferably disposed between the two pedals 3 and above the two pedals 3.

[0053] In this embodiment, as Figure 4As shown, as a specific embodiment, the reseter includes two reset ropes 5, and the two reset ropes 5 are respectively arranged at both ends of the swing arm. One end of each reset rope 5 is fixedly connected to the swing arm, and the other end is fixedly connected to the chassis 1. Two groups of calibration wheel 13 assemblies corresponding to the two reset ropes 5 one by one are arranged on the chassis. Each group of calibration wheel 13 assemblies includes two calibration wheels 13, and a channel is formed between the two calibration wheels 13, and the reset rope 5 passes through the corresponding channel. Specifically, two first rope winding posts 12 are provided on the chassis 1 and are respectively arranged on the left and right sides of the chassis 1, and two second rope winding posts 23 are provided on the swing arm 2 and are respectively arranged on the left and right sides of the swing arm 2. Both ends of each reset rope 5 are respectively fixed to the corresponding first rope winding post 12 and the second rope winding post 23.

[0054] In this embodiment, protrusions or massage beads can be arranged on the pedal 3 to increase the friction force or massage the soles of the feet. To improve safety, a stop block 31 can be arranged on the side of the pedal 3 away from the swing arm 2 to prevent the feet from slipping out of the pedal 3.
