Problems solved by technology

The transmission mechanism of the existing side-hung door generally adopts the form of connecting the door opener with the door post on the door leaf, so as to realize the rotation and opening of the single-leaf side-hung door along the rotating shaft, and the width of the door body is small; side hinged door
However, the conventional folding side-hung door cannot be opened by electric drive, and can only be opened or closed by manpower, and the folding fan of the side-hung door must be equipped with auxiliary supporting universal wheels before it can be used normally, which requires high road surface in the door opening.

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] This embodiment provides a folding door, such as figure 1 As shown, it includes an active door leaf 1 and a folding door leaf 2 hinged thereto. The active door leaf 1 is hinged to the door shaft 4 on the door post 3, wherein a rotary linkage mechanism 5 is arranged between the active door leaf 1 and the folding door leaf 2, as shown in FIG. figure 2 As shown, an "L"-shaped rigid toggle 5.1 is set on the rotary link mechanism 5, and the rotary link mechanism 5 is connected to the door post 3 through a pull rod 6 to realize 90° folding of the folding door leaf.

[0016] Further, a load-bearing bracket 7 is arranged on the active door leaf 1 and is hinged to the load-bearing hinge 8 on the door shaft 4 .

[0017] A drive mechanism 9 is arranged on the doorpost 3, and the drive mechanism 9 is connected with the active door leaf 1 through a drive cr...

Abstract

The invention relates to a folding door, in particular to a side-hung folding door with large width. The technical scheme includes that the folding door comprises a drive door leaf and a folding door leaf hinged with the drive door leaf, and the drive door leaf is hinged with a pivot on a door post. A rotary link mechanism is arranged between the drive door leaf and the folding door leaf, and an 'L'-shaped rigid crank is arranged on the rotary link mechanism which is connected to the door post through a pull rod. The folding door has the advantages that the folding door is suitable for electric side-hung doors with wide door openings, folding and unfolding of a door body occupy small space, the door body is not contacted with the ground in opening or closing, suspension operation has no requirement on pavement of the door openings, and the door body is simple in structure, reliable in operation, high in strength and high in wind resistance.

Description

technical field [0001] The invention relates to a folding door, in particular to a side-opening folding door with a large width. Background technique [0002] Large-sized door openings include telescopic doors that are opened or closed by telescopic means, and translation doors that are opened and closed by translational means. The strength of the retractable door is low, and the strength of the vertical hinged door is high. The transmission mechanism of the existing side-hung door generally adopts the form of connecting the door opener with the door post on the door leaf, so as to realize the rotation and opening of the single-leaf side-hung door along the rotating shaft, and the width of the door body is small; swing the door. However, the conventional folding side-hung door cannot be opened by electric drive, and can only be opened or closed by manpower, and the folding fan of the side-hung door must be equipped with auxiliary supporting universal wheels before it can b...
