Three-leg star shaped assembly structure for supporting chair legs

Abstract

The invention disclosure relates to the technical field of supporting chair legs, in particular to a three-leg assembly and disassembly structure for supporting chair legs in a star shape. The foot is movably connected to the end of the mounting part away from the central support. By providing a mounting groove and a connecting section, the connecting section of the supporting foot is vertically inserted into the mounting groove, so that the cylinder axis part is clamped into the limiting groove and then rotated the support foot upward ninety degrees, until the abutment section abuts against the limiting groove, the support foot can be installed.

1 . A star-shaped three-leg assembly and disassembly structure for supporting chair legs, comprising a central support, a mounting portion and a supporting leg, wherein the mounting portion is integrally fixed to an outer side wall of the central support, a support foot is movably connected to an end of a mounting part away from the central support, and a bottom end of the support foot is rotatably connected with a walking pulley, wherein a through slot is opened at a center of a top surface of the central support, and a connecting column is movably inserted in the through slot;
 wherein a mounting groove is opened at a head end of the mounting portion, two side walls of the mounting groove are integrally provided with a rotating groove, and an inner rear end of the mounting groove is positioned a limiting groove, a connecting section is integrally fixed at a tail end of the support leg, and a cylinder axis is removablyt inserted through a middle of the connecting section, and the rear end of the connecting section is integrally connected with an abutting section, wherein the abutting section sits in a horizontal direction when the abutting section of the support leg is locked to the mounting portion, wherein the mounting portion is distributed in an annular array aroune the outside center support; a shape of an inner wall of the insertion slot matches a shape of the outer wall of a connecting column, and the connecting column is movably inserted into an inside of the central suport through the insertion slot; wherein the limiting groove is formed by the inner wall of the mounting groove protruding toward the central support, and the limiting groove movably abuts below the abutting section: wherein the cylinder axis portion is cylindrical and protrudes from a side of the connecting section to both sides, and the length of the cylinder axis is greater than the width of the connecting section: wherein a length of the cylinder axis portion is greater than a distance between the two groove walls of the mounting groove, and the length of the cylinder axis portion is less than or equal to the distance between the two groove walls of the rotating groove.
