Folding door

Abstract

The invention discloses a folding door which comprises a first connecting shaft, a second connecting shaft parallel to the first connecting shaft, at least two door leaves and a slide rail. The door leaves are hinged to the first connecting shaft in a rotatable mode and freely swing with the first connecting shaft as the joint. Each door leaf is a geometric cylinder formed by at least four arc-shaped leaves and provided with a cavity in the middle, wherein the arc-shaped leaves are connected with one another with the second connecting shaft as the joint, hinged to the joint in a rotatable mode and folded and stretched around the joint so that the door leaf can be stretched out and drawn back. The slide rail is arranged at the upper ends or the lower ends of the door leaves so that the door leaves can slide to be folded and stretched along the slide rail. Each door leaf with the cavity in the middle is formed after the corresponding arc-shaped leaves are hinged to the connecting shaft in the rotatable mode, and therefore the sound absorption and thermal insulation functions of the door leaves are improved. Through concave-convex structures evenly arranged on the outer surfaces of the door leaves, sound is reflected, and the sound shielding effect of the door leaves is improved.

Description

technical field [0001] The present invention relates to a piece of furniture, and more particularly, to a folding door capable of soundproofing. Background technique [0002] The traditional roll-type folding door uses a plurality of blades to connect to form a door body, and then rolls the plurality of blades into a cylinder to achieve the purpose of folding. The gap between these blades is very large, and the blades are single-layer blades. The cavity is formed to block and absorb sound, so the sound insulation and sound absorption effect is extremely poor. [0003] The patent with the application number of 201110033198.X discloses a folding door, which utilizes large leaves to be folded together to form a door body, but the large leaves are single-layer leaves, and sound and heat can easily penetrate the leaves, so sound insulation cannot be achieved The effect of heat insulation, this invention does not structurally solve the problem of sound insulation and heat insulat...

Problems solved by technology

[0002] The traditional roll-type folding door uses multiple blades to connect to form the door body, and then roll the multiple blades into a cylinder to achieve the purpose of folding. The gaps between these blades are very large, and the blades are single-layer blades. A cavity is formed to block and absorb sound, so the sound insulation and sound absorption effect is extremely poor

[0003] Patent application No. 201110033198.X discloses a folding door, which uses large leaves to fold together to form a door body, but this large leaf is a single-layer leaf, and sound and heat can easily penetrate the leaf, so it cannot achieve sound insulation The effect of heat insulation, this invention does not solve the problem of sound insulation and heat insulation of the door leaf structurally, and because there is a half leaf at the joint of the leaf, there is a gap between the half leaf and the leaf, which is easy to be caught by the hand and affects the appearance
