Suspension folding door with double linkage rod linkage mechanism

Abstract

The invention relates to a suspension folding door with a double-frame connecting rod linkage mechanism, which relates to the field of doors adopting suspension folding movement as a feature. The suspension folding door with the double-frame connecting rod linkage mechanism comprises the suspension folding door and the double-frame connecting rod linkage mechanism. The suspension folding door is formed by a door post, a first door leaf and a second door leaf, wherein the first door leaf is arranged on the door post in a suspension way through a door shaft seat; the second door leaf is movably connected with the first door leaf through a hinge. The double-frame connecting rod linkage mechanism is formed by a first frame connecting rod, a second frame connecting rod and a triangular connecting rod; one end of the first frame connecting rod is hinged to one top end of the triangular connecting rod; one end of the second frame connecting rod is hinged to the other top end of the triangular connecting rod. A connecting mode of the suspension folding door and a double-single frame connecting rod linkage mechanism is characterized in that the other end of the first frame connecting rod is hinged to the door post, the other end of the second frame connecting rod is hinged to the door post; the third top end of the triangular connecting rod is hinged to the second door leaf. When the first door leaf is rotated, the second door leaf is rotated in a folding way relative to the first door leaf under the action of the double-frame connecting rod linkage mechanism. The suspension folding door with the double-frame connecting rod linkage mechanism is simple in structure, can realize synchronous linkage of the two door leaves, and has no pavement installation requirement.

Description

technical field [0001] The invention relates to the field of gates characterized by suspension folding movement, in particular to a suspension folding gate with a linkage mechanism of double linkage rods. Background technique [0002] Existing gates used for large-scale door openings mainly contain two types, one is a translation door that is opened and closed by a translation method, and the other is a telescopic door that is opened or closed by a telescopic method. These two types of gates have their own characteristics. The sliding gate has the advantages of high structural strength of the gate body, good reliability and strong protection ability, but it has the disadvantage of occupying a large area of ​​the site; the telescopic gate is mainly composed of the head assembly and several It is composed of movably connected door body components. In the contracted state, the site occupies a small area, but the structure is complex and the structural strength and reliability o...
