Example

This embodiment adopts the structure described in any one of Embodiments 1 to 6, and replaces the door leaf 2 with a window sash to form a folding window. The sash can adopt any existing structure of the folding sash, and a corresponding power shaft is installed in the sash 21 and flip axis 22.

The operation process of the folding door provided in the above embodiment is as follows, when the door leaf 2 (window sashes) is fully opened, that is, all the door leaves 2 (window sashes) are opened and stacked close to one side of the wall hole, and the other side of the wall hole is fully opened , can pass in and out. When it needs to be closed, start the driving motor, the driving motor drives the closed-loop chain 18 to rotate, and the active tackle moves with it and drives the first door leaf 2 (window sash) to move. With the cooperation of the hinge 7 between the door leaves 2 (window sashes), the movement of the active tackle will drive the subsequent passive tackle to move one after another, and the door leaf 2 (window sashes) will be gradually pulled open and flipped closed. At the same time, the turning shaft 23 of the last door leaf 2 (window sash) is limited relative to the turning structure 12 and cannot move relative to the turning structure 12. The turning and closing of the door leaf 2 (window sash) will drive the turning structure 12 to move along the guide rail 11 and Further impel all door leaves 2 (window sashes) to flip and close synchronously. In the same way, when the turning shaft 23 of the first door leaf 2 (window sash) moves to the extreme end of the turning structure 12, the turning shaft 23 is also equivalent to being unable to move relative to the turning structure 12, and the first door leaf 2 (window sash) and The last door leaf 2 (window sash) pulls and compresses the turning structure 12 from the front and rear ends, so that all the door leaves 2 (window sash) are completely flattened and closed on the door frame (window frame), so that the door leaf 2 (window sash) is closed more tightly. Tight, with better sealing, heat preservation and waterproof performance. At this time, the resistance spring 6 can be shortened by compression (embodiments one, two, three, five, six and seven) or elongated (embodiment four). On the frame 1, the door leaf 2 (window sash) will not move excessively with inertia, which will affect the use effect.

When it needs to be opened, the active block is driven to move in the reverse direction, and the active block drives the first door leaf 2 (window sash) to move in the reverse direction, and the first door leaf 2 (window sash) no longer tightens the turning structure 12 and even pushes the turning structure 12 to reverse. Moving in the opposite direction, the turning structure 12 will move in the opposite direction along the guide rail 11 with the thrust of the first door leaf 2 (window sash) under the action of resisting the deformation restoring force of the spring 6, so as to realize the turning and opening of the door leaf 2 (window leaf) and avoid The support between the door leaf 2 (window sashes) forms the supporting resistance to the driving block. The active tackle continues to move and will gradually fold the door leaf 2 (window sash) to one side of the wall hole to realize full opening. In practical applications, when the folding door is completely closed, it can be locked automatically by using a motor with a lock, or a door and window lock can be additionally set to lock the door leaf 2 (window sash).

The above-mentioned embodiments only express several implementations of the utility model, and the description thereof is relatively specific and detailed, but it should not be construed as limiting the patent scope of the utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the scope of protection of the utility model patent should be based on the appended claims.
