Concealed guided groove for fire-proof rolling curtain

Abstract

The present invention belongs to a roller shutter component, in particular, it relates to a channel guide for fire-resisting rolling shutter door. Said fire-resisting roller shutter invisible channel guide is formed from machine frame, movable column body and rotation drive structure, on the column surface of said movable column body at least one channel guide is set along the major axis direction of said movable column body, the described rotation drive structure is supported by machine frame, one end of the described movable column body is hinged on the machine frame and drive-connected with the rotation drive structure. The invented fire-resisting roller shutter invisible channel guide can implement lifting and falling operation according to the user's requirement.

Description

technical field [0001] The invention relates to a component of a rolling door, in particular to a guide groove for a fireproof rolling door. Background technique [0002] In public areas such as libraries and shopping malls, this product of fire-resistant rolling doors is generally used, such as the disclosed "fire-proof rolling doors" of utility model patent ZL01247697.8. When a fire breaks out, the above-mentioned fire shutter door is closed to separate the fire area from the non-fire area, thereby preventing the fire from spreading. For many years, the guide groove of the rolling shutter in the fire shutter door has been fixed. When the internal space of the building in the area that needs to be protected has a large span, or when the stairwell needs to be closed laterally, it is necessary to set up a special fixed column. The guide groove of the roller blind is arranged on the fixed column. For fire-proof rolling doors, there are not many cases where the rolling door i...

Problems solved by technology

But at ordinary times when there is no fire, although the curtain body of the rolling shutter door is in the retracted state, the column still stands upright on the ground due to the above-mentioned fixed setting, which not only takes up space, but also is inconvenient to pass, and is not attractive in appearance.

At the same time, from the perspective of safety, the size of the above-mentioned fixed columns is generally large, and the large-sized fixed columns will consume a large amount of steel and cement

Although this phenomenon has existed for a long time, those skilled in the art have turned a blind eye to it, thinking that this problem cannot be solved and avoided, thus forming a technical prejudice
