Description

Rolling door

Technical Field

The utility model relates to a rolling slats door.

Background

The rolling door is usually formed by connecting thin plates or a plurality of curtain sheets, when high wind pressure or other external force acts on a closed door curtain, the door curtain is easy to deform and apply pulling force to limiting units at two sides of the door curtain, and when the pulling force is too large, a guide rail or the door curtain is very easy to damage. In addition, the shape and the function of the roller shutter door in the prior art are single, and the commercial value of the large-breadth roller shutter door is not well utilized. In the current society with high price of advertisement space and limited advertisement position, the use value and commercial value of the facade are ignored by people and cannot be fully utilized.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a rolling slats door that good reliability, commercial utilization are high.

In order to achieve the above purpose, the utility model adopts the technical scheme that: a rolling shutter door comprises a door curtain, the bottom of the door curtain is provided with a counterweight rod, an advertisement curtain is arranged on the outer side of the door curtain, and the bottom of the curtain body of the advertisement curtain is connected with the counterweight rod.

Compared with the prior art, the utility model discloses there are following technological effect: the side part of the advertisement curtain positioned outside the door curtain is in a free state, so that the pressure applied to the door curtain can be greatly reduced, and the reliability of the rolling door is ensured. Moreover, the advertising curtain can fully utilize the space of the door opening, thereby greatly expanding the commercial value and increasing the income of users.

Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.

A rolling door comprises a door curtain 10 with a weight rod 11 at the bottom, an advertisement curtain 20 is arranged outside the door curtain 10, and the bottom of the advertisement curtain 20 is connected with the weight rod 11. When the door curtain 10 is unfolded and closed on the door opening, the counterweight rod 11 is positioned at the bottom of the door opening, the advertisement curtain 20 is unfolded along with the counterweight rod, at the moment, the advertisement curtain 20 positioned outside the door curtain 10 mainly bears external forces such as wind pressure and the like, the advertisement curtain 20 with the free side part changes the wind direction, the external force applied to the door curtain 10 is greatly reduced, and therefore components on the side part of the rolling door are protected, and the rolling door is prevented from being damaged.

Preferably, the top of the advertisement curtain 20 is connected to the advertisement rotating shaft 21, and the power source drives the rotating shaft 21 to rotate so as to wind the advertisement curtain 20 around the shaft body.

Specifically, as shown in fig. 2-4, the shaft 21 is mounted within a housing 22, and the housing 22 is attached to the underside, outside, or to a structure located outside the roller shutter housing 12 of the roller shutter housing 12.

The distance between the box body 22 and the door curtain 10 is less than 500mm, so that the phenomenon that the distance between the rest door curtains 10 of the advertisement curtain 20 is too large to influence the pressure reduction effect is avoided.

Specifically, in this embodiment, one end of the torsion spring sleeved on the rotating shaft 21 is fixedly connected to the box 22, and the other end is connected to the shaft body of the rotating shaft 21, and the torsion spring provides an elastic force to drive the advertisement curtain 20 to be wound on the rotating shaft 21. In other embodiments, a motor or other means commonly used in the art may be used as a power source for the rotating shaft 21.

Preferably, the housing 22 is made of ferromagnetic material, a strong magnet is disposed on the lower side/outer side of the roller shutter door housing 12 or on a structure located on the outer side of the roller shutter door housing 12, and the housing 22 is fixedly installed by magnetic force. The bottom of the advertisement curtain 20 is detachably matched with the weight rod 11 so as to facilitate the replacement of the advertisement curtain 20.
