An angle-adjustable waist twister

Technical field

The invention belongs to the technical field of fitness equipment, and in particular relates to an angle-adjustable waist twister.

Background technique

In the existing Chinese patent database, a patent named waist twisting and stretching combination trainer has been disclosed. The application number is CN202221771864.X and the application date is 2022-07-11. This utility model discloses a waist twisting and stretching combination. The training device includes a base, a casing, and a main casing board. The main casing board and the casing are rotatably arranged on the base. The main casing board is provided with a hinge seat and an angle support seat, and a pedal is hinged on the hinge seat. There is a support frame hinged on the pedal, and the angle of the support frame is adjustable on the angle support base. There is a rotation locking mechanism between the main plate of the housing and the base. When the pedal is supported by the support frame and the angle support base, the rotation locking mechanism locks On the base, if the pedal cannot rotate relative to the base, leg stretching training can be performed; when the pedal is placed flat on the main board of the housing, the rotation locking mechanism is separated from the base, and the pedal can rotate relative to the base, allowing waist twisting training . After adopting the above structure, it has the advantages of simple and compact structure, convenient function conversion and adjustment, integrating waist twisting and leg stretching training functions, and can meet different training requirements.

Detailed ways

The technical solution of the present application will be further described below in conjunction with the accompanying drawings and examples.

As shown in Figure 1-3, it is an angle-adjustable waist twister, which includes a frame body 1. The frame body 1 includes two longitudinal bars 2 arranged in parallel and spaced apart. One end of the two longitudinal bars 2 is connected by a cross bar 3. The frame body 1 The body 1 is provided with a rotating base 4. A rotating plate 5 is rotatably connected to the rotating base 4. A rotating plate 6 is detachably connected to the upper surface of the rotating plate 5. Both free ends of the rotating plate 5 are hinged with horizontal connecting rods 7.
