Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a folding door. Background Art

[0002] Due to the folding property of the folding door, it is suitable for a variety of scenarios, including home decoration, commercial places, offices, hospitals and schools, industrial plants, etc. The folding door is also particularly suitable for use in a small space. By opening and closing the folding door, the space can be flexibly changed, which not only ensures privacy but also maximizes the use of space. After searching, the patent with the announcement number CN206987648U discloses an automatic folding door, including a fixed column, a mounting bracket, a main folding door, an auxiliary folding door and a folding cylinder. The upper and lower ends of one side of the fixed column are respectively symmetrically provided with mounting brackets. The upper and lower ends of one side of the main folding door are respectively rotatably connected to the mounting brackets. A rotating plate is horizontally provided on the upper side of the main folding door. A folding cylinder is horizontally provided between the rotating plate and the fixed column. A main gear is horizontally fixed on a vertical main fixed shaft on one side of the folding door, and an auxiliary gear is horizontally fixed on an auxiliary fixed shaft on one side of the auxiliary folding door. Upper and lower connecting plates are horizontally arranged on the upper and lower sides of the main folding door respectively, and a folding transmission rod is horizontally arranged between one end of the upper connecting plate and the mounting bracket on the upper side of the fixed column. It can quickly and efficiently rotate and fold the two doors smoothly through a folding cylinder. However, it is convenient to fold in two stages, and the space occupied by folding is still not small enough. At the same time, the folding cylinder pushes the folding plate to drive the main folding plate to fold, which is more laborious to drive and has higher energy consumption. Therefore, a folding door is designed that can be folded in three stages to further reduce the occupied space and improve space utilization. At the same time, it is light and flexible to fold, and reduces the energy consumption of folding drive. Utility Model Content

[0013] (3) Beneficial effects

[0014] Compared with the prior art, the present invention provides a folding door with the following beneficial effects:

[0015] The folding door is provided with three-stage folding doors, which facilitates three-stage folding, reduces the occupied area as much as possible, and improves space utilization. The driving cylinder facilitates the bending, pushing and pulling of the folding door 2 in the middle position. When pulling, due to the action of the folding transmission mechanism between the folding door 2 and the folding door 1, the folding door 1 and the folding door 2 are driven to fold or unfold. At the same time, the driving cylinder is hinged to the folding door 2, and the folding is less labor-intensive than driving the folding door 1 to fold according to the lever principle, making the folding more lightweight and flexible, and further reducing the driving energy consumption. Under the action of the gravity of the folding door 3 itself, the folding door 3 can be driven to fold synchronously through cooperation with the folding transmission mechanism of the folding door 2 bracket, so that the folding door can be folded as a whole. The folding door can be folded in three stages, further reducing the occupied space and improving space utilization. At the same time, the folding is lightweight and flexible, and the folding driving energy consumption is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
