Description

Smoke curtain

The invention relates to a smokeproof curtain, in particular to an innovative structural type revealer which is simple in structure, maintenance-free and accurate in installation.

According to the current technical standards, the fireproof cloth sold on the market will not burn itself when it is almost burned. The material itself is only equivalent to being carbonized, and its appearance can still maintain its original appearance. Characteristics, therefore, are widely used in fire escape, protective clothing and other related fields, and in recent years have been applied to fire protection of large buildings, the biggest purpose is to prevent smoke from smashing around and creating flawless The people were bruised.

The main practice is to divide large public buildings (such as department stores) into multiple disaster prevention areas in advance. When there is a fire in any area, the fire alarm screen is used to isolate the fire scene to avoid the spread of high temperature and thick smoke to other areas. And to reduce the loss of life and property.

For the structure of the fireproof curtain, please refer to the new patent case No. M452220 (hereinafter referred to as the "case"), which mainly uses the fireproof curtain with the door rail structure to prevent the hot air flow on the fire site. In this case, a sleeve is respectively arranged on the two longitudinal sides of the fireproof curtain, and the fireproof curtain is pre-wound in a roll box by using a rotating shaft. When the fire occurs, the fire curtain is placed down, and the two sets are respectively sleeved on a corresponding guide. The operation mode of the case is detailed in the announcement manual, and will not be described here.

As described in the specification, the case may indeed provide the effect of preventing hot air from colliding when a fire occurs. However, this kind of conventional structural type has found that the following problems still exist in the actual use experience: in order to lay down the fireproof curtain, the friction between the inside of the sheath and the guide rod is reduced, usually before the installation of the fireproof curtain The talcum powder is pre-sprayed inside the bundle. However, the installation time and the use time may be separated by many years, even for a dozen or twenty years. During this standby period, it is difficult to sprinkle the talcum powder inside the bundle, and the talcum powder is prolonged. Under the action of external force, agglomeration may occur, and the effect of reducing the friction cannot be ensured; in addition, after the bundle is fixed and fixed for a long time in the standby time, the sleeve is prone to wrinkles, and the inner surface thereof is not smooth enough. In addition, under the above-mentioned factors that the function of reducing friction of talcum powder cannot be ensured, it is likely to prolong the time for the fireproof curtain to be completely lowered; in addition, the fireproof curtain that has been wound and fixed for a long time may be deflected after being released. As a result, the bottom end of the bundle cannot be accurately set on the guide rod, thus losing the function of preventing the hot air flow from being smashed.

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 expected by users, and is also related to the industry's efforts to develop breakthrough goals and directions.

Referring to Figures 1, 2 and 3, there is shown a preferred embodiment of the smoke curtain of the present invention, but such embodiments are for illustrative purposes only and are not limited by this structure in the patent application. The smoke curtain comprises a piece of fireproof cloth material 10, and a heat resistant rubber strip 20 is disposed on each side of the longitudinal direction of the fireproof cloth material 10, and a bottom weight of the fireproof cloth material 10 is laterally mounted with a weight. Structure 11. In the preferred embodiment of the present invention, the heat-resistant strip 20 is a flat-shaped structure having a flexible property, and the joint with the fire-resistant cloth 10 is located on the line of the heat-resistant strip 20. In the preferred embodiment of the present invention, the heat-resistant rubber strip 20 and the fire-resistant cloth material 10 are combined with each other in a sewn manner, and the sewing thread 30 generated after the sewing is disposed along the center line of the heat-resistant rubber strip 20 . The heat resistant rubber strip 20 and the fireproof cloth material 10 are combined to divide the heat resistant rubber strip 20 into a first side panel and a second side panel; when the smoke curtain is in a retracted state or is not subjected to an external force The first side panel of the heat resistant strip 20 is attached to the fireproof fabric 10, and the second side panel is laterally extended relative to the fireproof fabric 10.

With the above structural composition design, the operation of the present invention will be described as follows: Please refer further to the figures 3 and 4, the present invention is used in conjunction with a 门-shaped door frame 40 in actual use; 40 includes a box body 41 horizontally fixed to the upper side of the passage to be closed, and two rail structures 42 respectively fixed to the two ends of the box body 41 and extending vertically downward respectively, wherein the inner space of the rail structure 42 is The internal spaces of the casing 41 are in communication with each other. The inner side of each of the track structures 42 is longitudinally formed with a guiding groove 43 which communicates with the inner and outer spaces of the track structure 42. Each guiding slot 43 includes an elongated section 431 extending to the outer space of the rail structure 42 and an involute section 432 coupled to the elongated section 431. In the preferred embodiment of the present invention, the involute section 432 is The V-shaped shape is provided so that the guiding groove 43 has a funnel-shaped cross section in plan view. A motor 50 is attached to the casing 41. The motor 50 is electrically connected to a fire alarm or a smoke detector (not shown). The motor 50 is extended with a reel 51.
