[0033] Please refer to Figures 1-6 , the present utility model provides a technical solution: an impact-resistant and wind-resistant rapid soft door, including an opener housing 7 and a right housing 9. The lower end of the opener housing 7 is welded with a left track housing 2, and the lower end of the right housing 9 is welded with a right slideway housing 19;

[0034] A rolling curtain assembly with an automatic reset function is arranged inside the right housing 9. The rolling curtain assembly includes an arc slideway 11, a guide wheel 12, a straight rail guide groove component 13, a channel steel joint component 14, a reset wheel component 15, a self-drilling screw 24, and a snap chain 25. The arc slideway 11 is fixed inside the right housing 9 by screws. The straight rail guide groove component 13 is installed on the arc slideway 11 by screws. The guide wheel 12 is installed on the straight rail guide groove component 13 by screws. The channel steel joint component 14 is installed inside the right housing 9 by screws. The reset wheel component 15 is installed on the channel steel joint component 14. The snap chain 25 moves along the reset wheel component 15, the channel steel joint component 14, the arc slideway 11, and the guide wheel 12.

[0035] The surface of the door opener housing 7 is screwed with a support plate 6. Inside the door opener housing 7, a door opener control box motor 5 is installed. The output end of the door opener control box motor 5 is connected to a driving drum 4. The driving drum 4 is connected to a driven drum 3 through a chain and gears. The driven drum 3 is installed between the support plate 6 and the right housing 9. The driving drum 4 is drivingly connected to a snap chain 25 through a sprocket. The snap chain 25 is connected to its counterweight 10 through a curtain fastener 23. The snap chain 25 is in contact with the surface of the driven drum 3. The counterweight 10 is installed on the surface of the driven drum 3.

[0036] A door curtain 8 is arranged on the surface of the driving drum 4. The left track housing 2 is screwed with a left track component 1 on its surface.

[0037] The right slide housing 19 is screwed with a right slide component 18 on its surface. A damping spring 21 is arranged between each of the multiple screws and the right slide component 18.

[0038] The opposite surfaces of the left track component 1 and the right slide component 18 are both connected with POM polymer tracks 22. A plurality of curtain fasteners 23 are slidably installed inside each of the two POM polymer tracks 22.

[0039] A plurality of curtain fasteners 23 are all clamped on the door curtain 8. The other ends of the curtain fasteners 23 corresponding to the right side are all installed on the snap chain 25.

[0040] The door opener housing 7, the right housing 9, the left track housing 2 and the right slide housing 19 are all installed on the wall through expansion bolts 20.

[0041] An infrared photoelectric trigger 16 is electrically installed at the lower end of the right slide housing 19. An airbag 17 is installed at the lower end of the right slide housing 19.

[0042] When the door needs to be opened, the door opener control box motor 5 is started to drive the driving drum 4 to rotate. The rotation of the driving drum 4 drives the sprocket on the surface of the driving drum 4 to move. The sprocket on the driving drum 4 drives the snap chain 25 to move upward, driving a plurality of curtain fasteners 23 to move upward. At the same time, the driven drum 3 is driven by the counterweight 10 to accelerate the rotation of the driving drum 4, so as to increase the rate of rolling up the door curtain by the driving drum 4 to open the door.

[0043] Among them, a plurality of curtain fasteners 23 are stuck inside the corresponding POM polymer tracks 22, which can improve the wind resistance of the door curtain 8.

[0044] When the outside accidentally touches and impacts the door curtain 8, the curtain fasteners 23 corresponding to the right side of the door curtain 8 leave the inside of the corresponding POM polymer tracks 22, so as to protect the door body from being damaged due to being involved.

[0045] When the door is opened again, the buckle chain 25 drives the multiple curtain fasteners 23 to move, and through the adjustment of the reset wheel component 15, the channel steel joint component 14, the arc slide 11, the guide wheel 12, and the straight rail guide groove component 13, the multiple curtain fasteners 23 move along the buckle chain 25 back to the corresponding POM polymer track 22 during the movement, and the door body enters a normal state.

[0046] By arranging multiple curtain fasteners 23 to slide inside the corresponding POM polymer track 22, when the outside collides with it, the curtain fastener 23 will automatically detach from the inside of the POM polymer track 22 to avoid collision and damage to the door body, thereby protecting the door body. When it is necessary to restore the original state, it is only necessary to start the door opener control box motor 5 again to drive the sprocket on the active reel 4, thereby driving the snap chain 25 and then driving the corresponding curtain fastener 23 to move. The snap chain 25 moves the curtain fastener 23 along the reset wheel component 15 to the inside of the POM polymer track 22, restore the limit, thereby achieving a self-repair effect and avoiding affecting normal work.

[0047] By arranging a plurality of curtain fasteners 23 to slide inside the POM polymer track 22, the POM polymer track 22 can restrict the curtain fasteners 23, thereby improving the wind resistance of the door curtain 8 so that it will not be deflected or damaged when subjected to a wind of level 6-7.

[0048] By providing a counterweight 10, when the door is opened, the counterweight 10 pulls the driven reel 3 to rotate, thereby assisting in increasing the movement speed of the buckle chain 25, thereby increasing the door opening speed to 2.4 m / s.

[0049] By arranging two rows of damping springs 21 on the left track cover 2 and the right slideway cover 19, the buffering and vibration-damping capabilities of the door frame are improved, thereby reducing damage to the track caused by collision.

[0050] Working principle: When the door needs to be opened, the motor 5 of the door opener control box is started to drive the active reel 4 to rotate. The rotation of the active reel 4 drives the sprocket on the surface of the active reel 4 to move. The sprocket on the active reel 4 drives the buckle chain 25 to move upward, driving multiple curtain fasteners 23 to move upward. At the same time, the driven reel 3 is driven by the balance hammer 10 to accelerate the rotation of the active reel 4.

[0051] When the door curtain 8 is accidentally impacted by the outside world, the corresponding curtain fastener 23 on the right side of the door curtain 8 leaves the inside of the corresponding POM polymer track 22 .

[0052] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
