Description

Smoke screen

The invention relates to a smoke-proof curtain, in particular to an innovative structure type revealer with simple structure, maintenance-free and accurate and reliable installation.

According to the current technical level, the fireproof cloth sold on the market will not burn itself when it reaches an almost incinerated state. The material itself is only equivalent to being carbonized, and its appearance can still maintain the original Therefore, it is widely used in fire escape, protective clothing, and other related fields. In recent years, it has been used for fire protection of large buildings. Its biggest purpose is to prevent thick smoke from flowing around and innocent. The people were stung.

The main approach is to divide large public buildings (such as department stores) into multiple disaster prevention areas in advance. When a fire occurs in any area, use a fire curtain to isolate the fire scene to prevent high temperature and dense smoke from spreading to other areas. To achieve the purpose of reducing loss of life and property.

Regarding the structure of the fire curtain, please refer to China's new patent case No. M452220 (hereinafter referred to as "the case"), which mainly uses the fire curtain with the door rail structure to prevent the hot air flow from scrambling at the scene of the fire. The case was set up on each of the two longitudinal sides of the fire-resistant rolling screen, and the fire-resistant rolling screen was wound in a roll box in advance by using a rotating shaft. When the fire broke out, put down the fire shutter and make the two beams The sleeves are respectively set on a corresponding guide rod. For the operation method of this case, please refer to the announcement manual for details.

The case, as described in its description, may indeed provide the effect of preventing hot air from flowing in the event of a fire. However, this conventional structure type still found the following problems in practical experience: In order to reduce the friction between the inside of the sheath and the guide rod when the fire curtain is lowered, it is usually done before the fire curtain is installed. Spread talc powder inside the sleeve in advance. However, the installation time and usage time may be many years, or even ten or twenty years. During this standby period, it is difficult to spray talcum powder inside the sleeve. Under the action of external force, agglomeration may occur, and its effect of reducing friction cannot be ensured. Furthermore, after a long time winding and fixing of the sleeve at a standby time, the sleeve is prone to wrinkle, causing the internal surface to be not smooth. In addition to the factors that cannot be ensured by the aforementioned talc powder's function of reducing friction, I am afraid that the time required for the fire curtain to fully lower will be prolonged; in addition, the fire curtain that has been fixed for a long time may be flexed and deformed after release. As a result, the bottom end of the harness sleeve cannot be accurately set on the guide rod, thereby losing the function that it should provide to prevent the hot air flow from chaos.

Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure that is more ideal and practical is what the users expect, and it is also the goal and direction for relevant industry players to strive for breakthroughs.
