Foldable storage stool

Abstract

The invention provides a foldable storage stool, which has the advantages of simple structure, wear-resistant structure, good reliability and long service life. And the backrest, the stool includes a base plate, the backrest includes a hard plate, the hard plate and the base plate are rotatably connected by a hinge device, the first hinge of the hinge device is fixed on the upper surface of the base plate, and the second hinge is fixed on the lower surface of the hard plate Above, the two sides in the width direction of the first hinge are respectively provided with the first side walls along the length direction of the first hinge, and the two sides in the width direction of the second hinge are respectively provided with the first side walls along the length direction of the second hinge. Two side walls, one end of the two first side walls is respectively provided with a first connecting ear, one end of the two second side walls is respectively provided with a second connecting ear, the first connecting ear is correspondingly located inside the second connecting ear, the second connecting ear A limiting surface is provided on the outer side of the connecting ear, and the limiting surface cooperates with the second hinge to limit the rotation.

Description

technical field [0001] The invention relates to the technical field of stool structures, in particular to a folding storage stool. Background technique [0002] In the existing foldable storage stool, the stool cap is installed behind the stool seat to form a stool. For example, the Chinese invention patent with the notification number 203709630U discloses a foldable stool, which is provided with a foldable backrest by setting a hinge device. Its hinge device adopts a hinge structure with three sections connected to each other. It adopts the longitudinal limit surface of the hinge in the middle to cooperate with the hinges at both ends to limit the rotation. However, in actual use, we found that the section in the middle The longitudinal limit surface of the hinge is only a thin layer, and its limit structure is weak and cannot withstand high pressure. In actual use, when the user leans on the backrest, the limit structure will be dislocated and damaged due to excessive forc...

[0002] In the existing foldable storage stool, the stool cap is installed behind the stool seat to form a stool. For example, the Chinese invention patent with the notification number 203709630U discloses a foldable stool, which is provided with a foldable backrest by setting a hinge device. Its hinge device adopts a hinge structure with three sections connected to each other. It adopts the longitudinal limit surface of the hinge in the middle to cooperate with the hinges at both ends to limit the rotation. However, in actual use, we found that the section in the middle The longitudinal limit surface of the hinge is only a thin layer, and its limit structure is weak and cannot withstand high pressure. In actual use, when the user leans on the backrest, the limit structure will be dislocated and damaged due to excessive force of the user. As a result, the hinge structure is damaged, affecting the normal use of the backrest, making the folding storage stool poor in reliability and short in life, and the hinge structure can only realize that the backrest is perpendicular to the seat cushion, but this vertical backrest design is less comfortable to use
