[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the utility model.

[0018] As shown in the drawings, the utility model discloses a kind of plastic clamping pieces of anti-falling of folding screen door, including two pages 1, and rotating rod 2, rotating rod 2 has two fans ring 20, two the page 1 includes screen 11, and upper clamping piece 12 and lower clamping piece 13 inserted in screen 11, upper clamping piece 12 and lower clamping piece 13 are plastic integrated injection molding, this is the structure of existing folding screen door, screen 11 includes first rotating shaft 111, upper clamping piece 12 is provided with the second rotating shaft 121 corresponding to first rotating shaft 111, lower clamping piece 13 is provided with the third rotating shaft 131 corresponding to first rotating shaft 111, first rotating shaft 111, second rotating shaft 121 and third rotating shaft 131 are inserted in fan ring 20, and are rotationally connected in fan ring 20, first rotating shaft 111, second rotating shaft 121 and third rotating shaft 131 are all on the same vertical line, to form a rotating shaft whole rotationally connected in fan ring 20, the top of second rotating shaft 121 is provided with plug 3, plug 3 and second rotating shaft 121 are split structure, plug 3 is separate part, plug 3 is set to the upper end inside fan ring 20, and is fixedly connected with fan ring 20.

[0019] The utility model discloses a kind of plastic clamping pieces of anti-falling of folding screen door, by setting the plug 3 of split structure in the top of second rotating shaft 121, plug 3 is fixedly connected with fan ring 20, and plug 3 can prevent rotating rod 2 from loosening and falling due to second rotating shaft 121 in bottom top, to prevent scratching frame due to falling, while improving aesthetic sense and using fluency.

[0020] In the embodiment, the plug 3 is arranged in the fan ring 20, and the plug 3 and the fan ring 20 are interference fit, so that the plug 3 is clamped in the inner wall of the fan ring 20 to be fixed. Preferably, the upper end of the fan ring 20 is provided with a reduced section, and the plug 3 is arranged in the reduced section. It should be noted that the rotating rod 2 is a profiled strip, and the inner diameter of the fan ring 20 can be selected to be uniform. After the plug 3 is arranged in the fan ring 20, the fan ring 20 is extruded at the position corresponding to the plug 3 to form a reduced section, so that the plug 3 is clamped in the reduced section. Alternatively, the diameter of the plug 3 can be made larger than the diameter of the first rotating shaft 111, and the plug 3 is interference fit with the inner wall of the fan ring 20. The rotating rod 2 is sequentially inserted into the first rotating shaft 111, the third rotating shaft 131, and the plug 3 is arranged at the top of the second rotating shaft 121. Then, the rotating rod 2 is pulled upwards, so that the top of the fan ring 20 is matched with the plug 3.
