Detailed Description

Preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative, exemplary, and should not be construed as limiting the scope of the utility model.

As shown in fig. 1 and 2, the waist twisting disk 100 horizontally swings in different directions, and includes a base 10 for fixing placement and a swing disk 20 located above the base 10. The wobble plate 20 is used to support a body part of the human body including the back where the buttocks, feet or thoracic vertebrae are located. The body part is pressed against the wobble plate 20 and moves back and forth and left and right, so that the wobble plate 20 can perform translational movement at various angles on the plane in which the body part lies. Preferably, the translational movement has an elastic potential energy assistance, or elastic potential energy, which can reset the wobble plate 20.

In addition, a fixed platen 30 is fixedly connected to the swing plate 20 below the base 10. The fixed platen 30 moves or resets on the corresponding movable plane along with the swing plate 20, thereby achieving the training purpose. The existence of the fixed pressure plate 30 can perform the connection positioning function on the swinging plate 20 in the longitudinal direction, so as to prevent the swinging plate 20 from being accidentally separated from the through hole upwards.

Preferably, as shown in fig. 3 and 4, and fig. 5 and 6, the wobble plate 20 in the present embodiment substantially coincides with the cross-sectional area of the base 10. Standing still or when the swing plate 20 is reset, the swing plate 20 is vertically flush with the outer wall surface of the base 10 to form a 'coherent, integral' twist plate.

In actual movement, the swing plate 20 and the fixed platen 30 move horizontally on the upper and lower planes of the base 10, respectively. The swinging disc 20 is fixedly connected with the fixed pressing disc 30 through a positioning assembly.

Specifically, as shown in fig. 3 and 4, the base 10 in the present embodiment includes a circular bottom plate 11 and a first circular flange 12 disposed at the periphery of the circular bottom plate 11. Similarly, the wobble plate 20 includes a circular top plate 21 and a second circular flange 22 provided on the outer periphery of the circular top plate 21.

As shown in fig. 7 to 10, a rolling assembly 40 is disposed between the upper surface of the circular bottom plate 11 of the base 10 and the lower surface of the circular top plate 21 of the swing tray 20. The specific structure of the rolling assembly 40 will be described in detail below.

Further, the circular bottom plate 11 of the present embodiment is provided with a through hole 13 at the center.

The arrangement of the elastic members 15 is matched with the movement of the swinging discs 20 which can move at all angles on the same plane, so that the swinging discs 20 can be reset no matter in which direction the swinging discs 20 move. And the elastic potential energy of the elastic member 15 reset can be used as an assistance to the movement of the swinging plate 20 to a certain extent so as to improve the effectiveness of the movement.

Preferably, the elastic member 15 is a spring; in the first state, the tension of the plurality of springs causes the wobble plate 20 to coincide with the projection of the base 10. In the second state, the force applied to the wobble plate 20 by the limb portions (buttocks, waist, and back portion corresponding to thoracic vertebrae) causes the wobble plate 20 to be eccentric to the base 10. The eccentric amplitude of the wobble plate 20 is based on the spacing between the positioning assembly 50 and the inner wall of the through hole 13. In this case, the rolling member 40 in the present embodiment always moves within the range of the outer peripheral wall of the swing plate 20 and the base 10. That is, the movable range of the rolling assembly 40 is always within the first circular flange 12 or the second circular flange 22, so as to avoid the rolling assembly from deviating from the predetermined movable range.

In the third state, the total potential energy stored by the springs drives the wobble plate 20 to return to the original position.

More specifically, as shown in fig. 11 and 12, the positioning assembly 50 includes a positioning post 51 extending downward from the center of the lower surface of the circular top plate 21, and a positioning pin 52 extending upward from the center of the upper surface of the fixed platen 30.

The positioning support column c1 is provided with a connecting hole matched with the positioning support pin c2, and the connecting hole and the positioning support pin are tightly matched; or the connecting hole is a threaded hole, the positioning support pin is a screw, and the connecting hole and the positioning support pin are connected through threads.

The number of the positioning support pins c2 is matched with that of the positioning support posts c 1; the elastic member 15 is connected between the positioning stay c1 and the connection stay 15. Preferably, a connecting groove is formed at the lower part of the positioning support column c1 in this embodiment, and one end of the spring is hooked on the connecting groove.

In addition, in the present embodiment, the rolling assembly 40 is a cage 41 and a plurality of rolling balls 42 distributed on the cage 41. The retainer 41 is an annular frame, a plurality of positioning seats are distributed on the annular frame at intervals, and each positioning seat is provided with either a single steel ball hole or a double steel ball holes, and the single holes and the double holes are arranged at intervals. The aperture of the single hole is larger than the aperture of each hole in the double holes. This arrangement can simplify the structure of the rolling assembly itself while ensuring more flexibility in rolling the steel balls 42. But more flexible technical effect, especially with the oscillating disk 20 which can move flexibly in multiple directions.

Of course, in actual production, the setting of the fixed platen 30 at the bottom of the waist twisting plate 100 may be omitted. The above-described technical solution can also be realized by only making a longitudinal limit on the swing 20. Those skilled in the art can increase or decrease the number according to actual needs.
