Description

windproof rolling door

technical field

The invention belongs to the technical field of construction engineering, in particular to a windproof rolling shutter door.

Background technique

At present, in the construction field of building doors and windows, the area of doors and windows is getting larger and larger. For the doors of workshops, garages, and warehouses, many of them use rolling doors. However, the existing rolling doors are relatively wide, especially in the case of strong winds. Under normal circumstances, individual curtains are easy to be blown off the guide rails on both sides, resulting in damage to the rolling shutter door, especially in places where typhoons are frequent in coastal areas.

Contents of the invention

In order to solve the deficiencies in the prior art, the present invention provides a windproof rolling shutter door.

In order to solve the above technical problems, the present invention adopts the following technical scheme: a windproof rolling door, including a rolling box and vertical guide rails arranged on both sides of the lower part of the rolling box, a reel is arranged in the rolling box, and a power is provided on the reel The driving device is wound on the reel with curtains with both ends sliding up and down along the vertical guide rails, and a curtain windproof device is arranged between the upper parts of the vertical guide rails.

The windproof device for the curtain comprises a horizontal guide rail in a rectangular structure, a U-shaped windproof column and two pulleys with annular grooves. The pulleys are suspended and slidably connected to the two long sides of the horizontal guide rail through grooves.

The lower end of the vertical guide rail is horizontally provided with a rectangular limit frame, the limit frame is arranged outside the lower part of the windproof column, and the middle part of the limit frame is provided with a lock.

By adopting the above-mentioned technical scheme, the windproof device for the curtain plays a good windproof effect on the curtain, preventing the curtain from being bent by strong winds and falling out of the vertical guide rail. The curtain windproof device mainly adopts a U-shaped windproof column. The curtain dropped on the reel falls in the windproof column, that is, the two vertical bars of the windproof column are located inside and outside the door respectively. The locking buckle is equivalent to dividing the original wider curtain into two parts, adding a vertical support to the curtain and increasing the overall strength of the curtain. When there is a strong wind, it is not easy for individual curtains to be bent And the situation of breaking away from the vertical guide rail; when the reel lifts the curtain, it pushes the windproof column and moves to the side of a vertical guide rail along the two long sides of the horizontal guide rail through two pulleys. The limit frame plays a role in the stability of the windproof column when it moves horizontally from side to side, and the lock buckle fixes the windproof column to prevent the windproof column from swinging and shifting when strong wind blows.

If the rolling shutter door body is horizontally wide due to special needs, several windproof columns can be appropriately added to improve the windproof strength of the door body.

The invention is novel in design and simple in structure, greatly increases the strength of the curtain sheet of the rolling shutter door when it is hit by strong wind, avoids the situation that the curtain sheet is bent by blowing and falls out of the vertical guide rail, has strong practicability, and is easy to popularize and apply.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 is an enlarged side sectional view of the curtain windproof device in Fig. 1 .

Detailed ways

As shown in Fig. 1, a kind of windproof rolling door of the present invention comprises rolling shutter box 1 and vertical guide rail 2 that is arranged on both sides of the lower part of rolling shutter box 1, and rolling shaft 3 is arranged in the rolling shutter box 1, and is arranged on the rolling shaft 3 There is a power drive device 4, the power drive device 4 is a tubular motor, the reel 3 is wound with curtains 5 with both ends sliding up and down along the vertical guide rails 2, and a curtain windproof device is arranged between the vertical guide rails 2 tops.

The curtain windproof device includes a horizontal guide rail 6 in a rectangular structure, a U-shaped windproof column 7 and two pulleys 9 with annular grooves 8. Fixedly connected, two pulleys 9 are hung and slidably connected on the two long sides of the horizontal guide rail 6 through the groove 8.

The lower end of the vertical guide rail 2 is horizontally provided with a rectangular limit frame 11, and the limit frame 11 is arranged on the outer side of the bottom of the windproof column 7, and the middle part of the limit frame 11 is provided with a lock catch 12. The buckle 12 is an existing mature technology, and the specific structure will not be repeated.

When in use, the power drive device 4 drives the reel 3 to rotate, and the curtain 5 wound on the reel 3 is put down along the vertical guide rail 2, and the curtain 5 just falls in the middle of the windproof column 7, that is, the two rods of the windproof column 7 are located at the door respectively. Inside and outside the door, then promote the windproof post 7 to move to the middle part of the horizontal guide rail 6 along two long sides of the horizontal guide rail 6 by two pulleys 9, and the lock catch 12 fixes the windproof post 7 and the limit frame 11. The windproof column 7 fixes all the curtains 5 as a whole, which increases the overall strength of the curtains 5. When there is a strong wind, it is difficult for individual curtains 5 to be bent and break away from the vertical guide rail 2 again. When the shutter door needs to be opened, the reel 3 lifts the curtain sheet 5, opens the lock catch 12, promotes the windproof column 7, and moves to a vertical guide rail 2 along two long sides of the horizontal guide rail 6 by two pulleys 9.
