Description

Technical Field

[0001] This invention relates to the field of folding door technology, specifically to a folding door with a stable structure. Background Technology

[0002] A folding door is a type of door that folds along a track using hinges. In home decoration, folding doors are often installed in areas with large door frames to improve the utilization of interior space. When folded, folding doors increase the passage area of ​​the door frame. Folding doors are mostly made of aluminum alloy and can be customized with different patterns to enhance the aesthetics of the decor. When installing a folding door, a sliding track of appropriate length needs to be installed according to the size of the door frame. Then, multiple door panels are connected by a pivot. Rollers are installed on the pivot and inside the sliding track, allowing the door panels to rotate around the pivot when pushed, thus folding and unfolding, closing and opening the door frame.

[0003] However, modern folding doors are prone to gaps at the pivot point between the two door panels, resulting in poor sealing. Furthermore, when closing the door with excessive force, the folding door can close too quickly and cause injury to people. Summary of the Invention

[0010] Preferably, the end of the contact wheel is attached to the surface of the connecting rod, and the contact wheel is an elastic wheel made of rubber.

[0011] Preferably, the stabilizing mechanism comprises a sliding groove, a moving block is slidingly connected in the inside of the sliding groove, the side of the moving block close to the bottom of the sliding groove is fixedly connected with a compression spring, the inside of the mounting frame is provided with a guide rod, the side wall of the guide rod is fixedly connected with a guide plate, the bottom of the guide rod is fixedly connected with a return spring, and the end of the guide rod is fixedly connected with a rubber block.

[0012] Preferably, the sliding grooves are arranged in the inside of the protrusion, and there are a plurality of sliding grooves which are uniformly arranged around the central axis of the protrusion.

[0013] Preferably, the moving block and the guide plate are located on the same horizontal plane, and there are a plurality of guide plates which are uniformly arranged on the side wall of the guide rod.

[0015] Preferably, the two sides of the connecting plate are provided with circular grooves which are inserted on the connecting columns of the two side door plates.

[0016] (Three) beneficial effects

[0017] Compared with the prior art, the present application provides a folding door with a stable structure, which has the following beneficial effects:

[0018] 1. The side of the door plate is rotatably connected with the connecting rod, the connecting rod is rotatably connected with the mounting frame through the rotating shaft, and the two sides of the mounting frame are rotatably connected with the door plates, so that the position of the rotating shaft between the two door plates is provided with the mounting frame, and the mounting frame can block the gap between the two door plates, thereby achieving the effect of blocking the connection between the two door plates and improving the sealing performance of the folding door.

[0019] 2. When the door plate is closed, the rotating speed is fast, the rotating speed of the rotating disc driven by the support rod is fast, at this time the stabilizing mechanism is triggered, the friction between the rubber block and the connecting rod is increased, and the rotating speed of the door plate is reduced, thereby achieving the effect of avoiding the injury caused by the fast movement of the door plate when closing.

[0020] 3. The support rod, driven by the push-out spring, causes the contact wheel to roll on the surface of the connecting rod, providing a certain support force to the pivot of the door panel, reducing the vibration when the door panel rotates. When the door panel rotates too fast, the stabilizing mechanism slows down its rotation speed, thereby improving the stability of the folding door during movement. Attached Figure Description
