The detailed description and technical content of the present invention are described in conjunction with the drawings as follows: Please refer to FIG. 1, the present invention provides a fire-proof smoke shielding curtain 10 which is implemented with two spaced door rails 20 to form a fire-proof shield In the cigarette door 30, the fire shielding smoke screen 10 is in a normal state, that is, when a fire alarm does not occur, the fire shielding smoke screen 10 will be hidden and It cannot be observed from the appearance of the fireproof and smoke shielding roller door 30. Once a fire alarm occurs, the fireproof and smoke shielding roller screen 10 is lowered by a driving device 31 to move the fire and smoke shielding roller screen 10 in the two door rails 20, As shown in Figure 2.

Please refer to FIGS. 2 to 4 to explain the structure of the door rail 20 first. Each door rail 20 of the present invention has a hollow area 21 and a guide curtain channel 22 connecting the hollow area 21. Specifically, the guide curtain The channel 22 is formed by two spaced-apart flat plates 221 with a channel width 222 between the two plates 221, and the portion of the fireproof smoke shielding roller screen 10 located at the guide screen channel 22 has a first roller screen thickness 11, the The thickness 11 of the first rolling curtain is smaller than the width 222 of the channel, so that the fire-proof and smoke-shielding rolling curtain 10 can be worn therein. Further, two sides of the fireproof smoke shielding roller 10 are provided with two lugs 12 and 13 along the sides. In one embodiment, the two lugs 12 and 13 can be integrally formed on the fireproof smoke shielding roller 10, that is, the two The lugs 12 and 13 can be formed by folding the fire-proof and smoke-shielding roll 10 respectively, or the two lugs 12 and 13 can be connected to the same side of the fire-proof and smoke-shielding roll 10 by any combination such as stitching and bonding . After the two lugs 12 and 13 are connected to the fireproof and smoke shielding roller 10, the two lugs 12 and 13 on the same side are located at two opposite points 14 and 15 on both sides of the fire and smoke shielding roller 10, respectively.

Referring again to FIG. 3, each lug 12(13) of the present invention has a first arc-shaped segment 121(131) and a second arc-shaped segment connected head to tail of the first arc-shaped segment 121(131) 122 (132). In one embodiment, the first arc-shaped segment 121 (131) and the second arc-shaped segment 122 (132) are formed by bending the same sheet, that is, the first arc The segment 121 (131) is integrally formed with the second arc-shaped segment 122 (132). Moreover, the sheet material may be a cloth material. Further, during implementation, the two lugs 12, 13 on the same side are disposed in the same hollow area 21, and the connection between the two lugs 12, 13 and the fire-proof smoke shielding curtain 10 has a larger than the guide Curtain channel 22 of the second roll thickness 16.

Next, please refer to FIG. 3 and FIG. 5 again to describe the embodiment of the fireproof smoke shielding roller 10, and since the embodiment of the fireproof smoke shielding roller 10 is the same on both sides, the fireproof smoke shielding roller 10 will be described on one side. First, suppose that at the initial stage, a fire alarm occurs and the fire shielding smoke curtain 10 has descended along the door rail 20. The fire shielding smoke curtain 10 was not subjected to the heat flow in the initial stage, so that the two lugs 12, 13 are located in the hollow area 21 Inside, and is not limited, more specifically, because the two lugs 12, 13 are not pulled by the fire shielding smoke roll 10, the connection between the two lugs 12, 13 and the fire shielding smoke roll 10 is not blocked The guide curtain channel 22. Once the fire shielding smoke screen 10 is subjected to the hot air flow, the portion of the fire shielding smoke screen 10 facing the hot air flow will be shifted in the direction of the hot air flow. At this time, the fire shielding smoke screen 10 will pull the two convexes The ears 12 and 13 make the connection between the two lugs 12 and 13 and the fire and smoke shielding curtain 10 and close the guide channel 22. In addition, the two lugs 12 and 13 located on the other side of the fire shielding smoke screen 10 will similarly close the guide curtain channel 22 when the fire shielding smoke screen 10 is pressed by the hot air flow. At this time, due to each of the door rails 20 Both are closed by the two lugs 12 and 13 so that the hot air flow cannot enter the hollow area 21, so that the fireproof smoke shielding curtain 10 can prevent the hot airflow from entering the fireproof smoke shielding curtain 10 without hot airflow one side.

As mentioned above, through the present invention, the fire and smoke shielding curtain 10 can be implemented in combination with the existing door rail 20 structure without special design of the door rail 20. In addition, the present invention is provided with the lugs 12 and 13 so that no additional components need to be used on the fire shielding smoke roll 10 to achieve the purpose of preventing hot air flow. Compared with the conventional one, the present invention is simpler in structure , So that the fire smoke shielding curtain 10 can be more widely used.

In one embodiment, please refer to FIG. 3 and FIG. 5 again, each lug 12 (13) is not sewn to one end of the fire-proof smoke screen 10 as a free end 124 (134), and each lug 12(13) When not pulled by the fireproof smoke screen 10, each of the lugs 12(13) can move in the hollow area In domain 21. When the fire shielding smoke screen 10 is compressed by the hot air flow, the fire shielding smoke screen 10 is compressed and pulls the connection between the fire shielding smoke screen 10 and the two lugs 12, 13 so that the connection will be blocked by the guide curtain Channel 22, at this time, the first arc-shaped section 121 (131) of each lug 12 (13) will contact the guide curtain channel 22, thereby making each lug 12 (13) interfere with the guide curtain channel 22 The deformation or displacement in the direction away from the guide channel 22 occurs. It is worth noting that the drawing formula of the present invention is only an illustration, that is to say, the fireproof and smoke shielding roller 10 may be different according to the actual state during implementation.

In yet another embodiment, and referring to FIGS. 7 and 8, each of the lugs 12 (13) defines a first arc segment 121 (131) and the second arc segment 122 (132) A tubular space 123 (133), and each inner side of the door rail 20 has at least two auxiliary ropes 23, 24 respectively corresponding to one of the lugs 12 (13), more specifically, each auxiliary rope 23 (24 ) Is provided in the tubular space 123 (133) of each lug 12 (13), and one end of the auxiliary rope 23 (24) is weighted and fixed so that each auxiliary rope 23 (24) is implemented There will be no displacement. Specifically, when the fireproof smoke shielding curtain 10 is forced by the hot air flow, the two lugs 12, 13 are pulled by the fireproof smoke shielding curtain 10 and the fireproof smoke shielding curtain 10 and the two lugs 12, 13 The connecting place closes the guide channel 22. Once the hot air flow is too strong, the fire shield smoke screen 10 will vigorously pull the two lugs 12, 13 so that the two lugs 12, 13 are extremely compressed and are squeezed into the guide curtain channel 22. In addition, since the two auxiliary ropes 23 and 24 are located in one of the lugs 12 (13), respectively, the two lugs 12 and 13 can specifically increase the two lugs 12 and 13 and the fireproof smoke shielding curtain 10 The thickness of the joint makes the two lugs 12 and 13 not disengage from one of the door rails 20 even when the fireproof smoke shielding curtain 10 is extremely pulled. In this way, according to the present invention, the two auxiliary ropes 23, 24 are arranged so that the two lugs 12, 13 will not be separated from one of them The door rail 20 can prevent the fire and smoke shielding curtain 10 from falling off the two door rails 20 due to excessive hot air flow, and can effectively block the flow of dense smoke.

In summary, the above is only a preferred embodiment of the present invention, and it should not be used to limit the scope of the present invention, that is, all changes and modifications made according to the scope of the patent application of the present invention should still belong to the present invention Of patent coverage.
