Abstract
The present disclosure provides a foldable small flying and squat rack, which comprises a fixed rack, a pivot rack and pulley blocks disposed on the fixed rack and the pivot rack, wherein the pivot rack can rotate relative to the fixed rack, a counterweight assembly is disposed at the lower part of the fixed rack, and a connecting rope is connected at the upper part of the counterweight assembly; the connecting rope winds around the pulley blocks on the fixed rack and the pivot rack in turn to extend out, and then passes through a flying guide wheel to be connected to a grip part.
Claims20
A foldable small flying and squat rack, comprising
- a fixed rack, pivot racks and pulley blocks disposed on the fixed rack and the pivot racks, wherein the pivot racks comprise two pivot racks that are respectively rotatably connected to the fixed rack;
- and
- a counterweight assembly connected with the fixed rack in a sliding manner, wherein an upper part of the counterweight assembly is connected with a connecting rope-, which winds around the pulley blocks on the fixed rack and the pivot racks in turn to extend out;
- wherein each of the two pivot racks is provided with a pivot wheel set mechanism, and a connecting sheet is fixedly disposed on the pivot wheel set mechanism;
- and a rotary inner cylinder is fixedly disposed on the connecting sheet, and the pivot racks are rotatably connected with the fixed rack through the rotary inner cylinder;
- and the connecting rope passes through the rotary inner cylinder, and a pulley block of the pulley blocks comprises a first deflecting pulley and a second deflecting pulley, which are respectively disposed above and below the rotary inner cylinder;
- and
- wherein, a part of the connecting rope located at the position of a rotating axis of the rotary inner cylinder is always in a vertical state, and a tangent point of the connecting rope winding out of the first deflecting pulley and into the second deflecting pulley is located on the axis of the rotary inner cylinder, so as to avoid the connecting rope from being dragged by the rotation of a pivot rack of the pivot racks.
