[0002] Folding doors are mainly suitable for partitions and screens in workshops, shopping malls, office buildings, showrooms and home decoration. They can be installed and used as inner and outer doors. They can effectively play the role of heat insulation, dust prevention, noise reduction, and shielding. According to different styles, folding doors are divided into side-mounted folding doors and sliding folding doors. Folding doors are multi-leaf folding doors that can be pushed to the side and take up less space.

[0003] The prior art patent document CN221856544U provides a household folding door with a supporting anti-collision structure. After the door panel body is closed, the inclined block is blocked by a block. Therefore, if the door panel body is hit when the door panel body is closed, the impact force is transmitted from the door panel to the inclined block, and then transmitted to the crossbeam through the block, so that the impact force is finally borne by the crossbeam, thereby improving the anti-collision ability of the folding surface and improving the overall strength of the folding surface after closing.

[0004] Although the above-mentioned existing technology can fold the door and prevent collisions when impacted, it can only prevent collisions with smaller impacts during use. When the impact is larger, the door leaf is easily concave and deformed. The structural strength of the door leaf itself in the folding door is not high, and the anti-collision effect is not very good, which cannot meet people's needs. Therefore, we need an inward-opening anti-collision folding door. Utility Model Content
