Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present utility model. It will be apparent, however, to one skilled in the art that the utility model may be practiced without one or more of these details. In other instances, well-known features have not been described in detail in order to avoid obscuring the utility model.

In order to provide a thorough understanding of the present utility model, detailed steps and detailed structures will be presented in the following description in order to explain the technical solution of the present utility model. Preferred embodiments of the present utility model are described in detail below, however, the present utility model may have other embodiments in addition to these detailed descriptions.

Referring to fig. 1-2, the present utility model provides a sealed shutter door wherein the door leaf 10 of the shutter door is comprised of a plurality of elongated stiles enclosing a rectangle and a plurality of parallel arranged vanes 20 positioned within the stiles.

Each stile can be made of hollow aluminum materials and is internally provided with reinforcing ribs to ensure strength. The connection between the left side stile 11/right side stile 12 and the upper side stile 14/lower side stile 13 can be in the form of a plug connection, a screw connection or by means of a corner brace or the like. As shown in the figure, angle code slots 17 and screw holes 18 are formed in two ends of each stile, and after metal angle codes are inserted into two adjacent stiles, the two stiles are fixedly connected by screws.

The upper and lower ends of the left stile 11 and the right stile 12 are provided with notches 19 for inserting the left and right ends of the upper stile 14 and the lower stile 13, and the four stiles are more firm after being connected.

The left stile 11 or the right stile 12 is provided with a handle 30 to facilitate pulling the whole door leaf.

One end of each fan blade 20 is rotationally connected with the left stile 11 through a rotating shaft, the other end of each fan blade 20 is provided with a transmission gear 21, the transmission gear 21 is simultaneously meshed with two parallel racks in the right stile 12, a first rack 22 is fixedly arranged in the right stile 12, and a second rack 23 is slidably arranged in the right stile 12. When any one of the fan blades 20 is shifted, the transmission gear 21 of the fan blade 20 rotates along with the fan blade and drives the second rack 23 to slide, and the second rack 23 drives the transmission gears 21 of the rest of the fan blades 20 to rotate in the same direction, so that synchronous rotation of all the fan blades 20 is realized.

The transmission gear 21, the first rack 22 and the second rack 23 are all made of plastics, so that the transmission noise is low, and the manufacturing cost and the replacement cost are low.

Fig. 7 shows a connection manner between the driving gear 21 and the fan blade 20 in an embodiment, a waist-shaped circular insertion block 25 is disposed at one end of the driving gear 21, and correspondingly, a waist-shaped circular insertion hole 24 is disposed at one end of the fan blade 20, and the shaped insertion block 25 is inserted into the shaped insertion hole 24 to fixedly mount the driving gear 21 on the fan blade 20. The special-shaped plug block and jack design is adopted, so that the transmission gear 21 and the fan blade 20 are connected into a whole, and the phenomenon that the transmission gear and the fan blade generate relative sliding is avoided.

In order to improve the sealing performance of the shutter door, the utility model provides targeted improvement for both the fan blade and the door frame. We will make the side section of the fan blade 20 in a parallelogram, and the angle α between the front end surface and the upper and lower end surfaces of the fan blade 20 is 45 ° or 135 °, as shown in fig. 6. When the fan blades 20 are stirred to be in a vertical state, the shutter door is closed, the front end face and the rear end face of the fan blades 20 are flush to form a flat surface, the integrated effect is stronger, dust is not easy to accumulate, the adjacent end faces of the upper fan blades 20 and the lower fan blades 20 form wedge-shaped fit, and the tightness is better. In addition, the lower stile 13 and the upper stile 14 are respectively provided with a lower vertical baffle 15 and an upper vertical baffle 16 which are positioned on the front side and the rear side of the rotating shaft, the lower part of the front side of the lowermost fan blade 20 is attached to the lower vertical baffle 15, the upper part of the rear side of the uppermost fan blade 20 is attached to the upper vertical baffle 16, and the upper vertical baffle 16 and the lower vertical baffle 15 shield the gap between the upper fan blade 20 and the lower fan blade 20 and the inside of the door frame, so that the sealing effect is further improved, as shown in fig. 5. Compared with the existing shutter door/window, the sealing shutter door provided by the utility model can better separate air and light on the inner side and the outer side of the door after the fan blades are closed.

In an alternative embodiment, the wedge-shaped surfaces 27 of the upper and lower end surfaces of the fan blades 20, the rear side surface of the lower vertical baffle 15 and the front side surface of the upper vertical baffle 14 are provided with flexible materials, and when the fan blades 20 are closed, the flexible materials can further eliminate gaps between the fan blades and gaps between the upper and lower fan blades 20 and the inside of the door frame, so that the sealing effect is further improved.

The blade 20 may be made of a material customized according to the preference of the customer, for example, may be made of solid wood, or may be made of PVC material with reinforced metal strips inside, thereby improving strength.

It should be noted that the above-mentioned "up", "down", "left" and "right" are relative concepts, and do not limit the protection scope of the present utility model specifically, the fan blade in the drawing is turned up and down to implement opening and closing, in practical application, the fan blade may be turned left and right to implement opening and closing, so that the corresponding up and down directions and left and right directions need to be interchanged, and those skilled in the art can change the directions according to the practical requirements.
