It can be installed and used as both inner and outer doors. It can effectively play the role of heat insulation, dust prevention, noise reduction, sound insulation, and shielding.

[0003] When currently using folding doors, it is often impossible to quickly open the folding doors, which affects the convenience of opening the folding doors. In addition, the folding doors are often inconvenient to store and process after being unfolded, which makes it easy for folding doors used in households to occupy space after being unfolded, thereby affecting the practicality of the folding doors and wasting space resources when in use. Therefore, we propose a fast hard folding door. Utility Model Content

[0021] Example

[0022] See also Figures 1 to 4 In an embodiment of the utility model, a fast rigid folding door includes a door frame 1, and a bottom plate 2 is arranged at the bottom of the door frame 1. Under the action of the door frame 1 and the bottom plate 2, it is not only convenient to install the door, but also ensures the stability of the door during actual use, thereby ensuring the use efficiency of the door.

[0023] The door frame 1 is provided with a slide groove on the left and right inner walls, and a limit block 15 is slidably provided in the slide groove, and a mounting shell 6 is provided on the limit block 15. The mounting shell 6 is provided with a mounting plate 8 on the left and right sides of the front outer wall, and a first rotating shaft 801 is provided at the bottom of the mounting plate 8. The first rotating shaft 801 is rotatably provided with a first door panel 4, and a second door panel 5 is provided on the inner side of the first door panel 4 through a hinge. The mounting shell 6 is also slidably provided with two left and right sliders 16, and the front ends of the left and right sliders 16 are provided with a fixed block 9, and the bottom of the fixed block 9 A second rotating shaft 901 is provided, and the second rotating shaft 901 is rotatably connected to the second door panel 5. In actual use, when the door needs to be folded and opened, the left and right sliding blocks 16 are used to drive the fixed block 9 to move to both sides, thereby driving the second door panel 5 to move to both sides. At this time, under the action of the second rotating shaft 901, the hinge and the first rotating shaft 801, the first door panel 4 and the second door panel 5 can be folded and stored, and the mounting shell 6 can be moved to the rear side at the same time, so that the door can be further stored.

[0024] A bidirectional screw 7 is also rotatably provided inside the mounting shell 6, and the bidirectional screw 7 passes through the left and right sliders 16 and is slidably connected to the left and right sliders 16. At this time, rotating the bidirectional screw 7 can drive the left and right sliders 16 to move closer or farther away, thereby realizing the folding of the door panel. A cavity is also provided inside the mounting shell 6, and the bidirectional screw 7 passes through the side wall of the cavity and extends into the cavity. A first bevel gear 10 is provided on the bidirectional screw 7 in the cavity through a key connection, and a rotating shaft 11 is also rotatably provided in the cavity. A second bevel gear 12 is provided on the rotating shaft 11 through a key connection, and the second bevel gear 12 is meshed with the first bevel gear 10. At this time, the bidirectional screw 7 can be driven to rotate through the second bevel gear 12 and the first bevel gear 10 through the rotating shaft 11, thereby driving the slider 16 to move, and then the door is folded.

[0025] A worm wheel 13 is also provided on the rotating shaft 11 above the second bevel gear 12 through a key connection, and a worm 17 is also rotatably provided in the cavity. The worm 17 is meshed with the worm wheel 13. At this time, rotating the worm 17 can drive the worm wheel 13 to rotate, thereby utilizing the rotating shaft 11, the second bevel gear 12 and the first bevel gear 10 to drive the bidirectional screw 7 to rotate, thereby folding the door. In addition, because the worm wheel 13 and the worm 17 have a self-locking function, it is ensured that the state of the door after folding can be limited, thereby ensuring the folding quality of the door. A motor 1701 is also provided on the outer wall of the door frame 1, and the power output shaft of the motor 1701 is connected to the worm 17 through a coupling, and the motor 1701 can drive the worm 17 to rotate.

[0026] An electric push rod 14 is also provided inside the door frame 1. The end of the telescopic arm of the electric push rod 14 is connected to the mounting shell 6. The electric push rod 14 can be used to drive the mounting shell 6 to move back and forth inside the door frame 1. A protective cover plate 3 is also provided on the door frame 1 on the front side of the mounting shell 6. Under the action of the protective cover plate 3, the mounting shell 6 and its constituent components can be protected, thereby ensuring the use efficiency of the door.

[0027] During actual use, when the door needs to be folded, the staff starts the motor 1701 to drive the worm 17 to rotate, thereby driving the worm wheel 13 to rotate, and then driving the bidirectional screw 7 to rotate through the rotating shaft 11, the second bevel gear 12 and the first bevel gear 10, so that the left and right sliders 16 move to both sides. The movement of the slider 16 drives the fixed block 9 and the second rotating shaft 901 connected to its bottom to move to both sides, thereby driving the second door panel 5 to move to both sides. In this process, since the second door panel 5 is connected to the first door panel 4 through a hinge, and the first door panel 4 is connected to the mounting plate 8 through the first rotating shaft 801, therefore, under the joint action of the second rotating shaft 901, the hinge and the first rotating shaft 801, the first door panel 4 and the second door panel 5 can be smoothly folded and stored. After the door is folded and stored, the electric push rod 14 is used to drive the mounting shell 6 to move to the rear side, so that the door is further stored.
