Double track heavy hanging folding door

Abstract

Disclosed is a double track heavy hanging folding door which comprises a door body and a combined fixed frame located on the periphery of the door body and used for mounting the door body. The door body comprises a first folding door body and a second folding door body which oppositely join together and have the same structure, wherein the first folding door body comprises a plurality of folding door leaf units rotatably connected together. The combined fixed frame comprises an upper combined sliding way and a lower combined sliding way which are located on the upper portions and the lower portions of the folding door leaf units correspondingly and slidably matched with the folding door leaf units. Vertical edge frames rotatably connected with the folding door leaf unit on the outmost side are fixed to the two corresponding ends of the upper combined sliding way and the lower combined sliding way. According to the double track heavy hanging folding door, the larger span and opening space are achieved, bearing capacity is higher, pushing and pulling are quite flexible and easy, using is convenient, sealing performance is good, waterproof performance is high, wind pressure resistant performance is high, and the appearance is concise and harmonious.

Description

technical field [0001] The invention relates to a folding door, in particular to a double-track heavy hanging folding door. Background technique [0002] Folding door is a kind of foldable door suitable for wider openings. It is divided into two types: side-mounted folding door and push-pull folding door. It has the characteristics of multiple folding, which can be pushed to the side and takes up less space. . [0003] The folding door structure is mainly composed of door frame, door leaf, transmission parts, pivoting arm parts, transmission rod, orientation device, etc. The number of folding door leaves is reasonably set according to the width of the door opening. Although the folding door has the advantages of good applicability and easy use, its The hardware used in the assembly is complicated, the installation requirements are high, it is easy to wear, and the actual use cost is also high. [0004] Currently commonly used folding door structure, such as a folding door ...
