However, although the conventional technology can effectively control the flow of smoke and the spread of fire, the structural design is more complicated, the assembly is difficult and the cost is higher. How to further solve the complex structure and reduce the cost and increase the durability, etc. It is an important research and development topic of the airtight structure of the fire-resistant rolling door box.

The invention relates to an airtight structure of a fireproof rolling door box body, which has a fireproof rolling door box body, each of which is provided with a door rail, and a driving device is arranged in the fireproof rolling door box body, the driving device is connected to a reel, and the reel A fire-resistant rolling screen is wound. The fire-resistant rolling screen is driven by a driving device to be rolled up or rolled down. The opening is a channel formed by the first side wall and the second side wall bent by the fire-resistant rolling door box correspondingly inward, and a C-shaped ring is respectively set at one end edge of the opening formed by the first side wall and the second side wall. In the case of a fire, the surface of the fire-resistant rolling screen that is pressed during a fire is tightly blocked on the end edge of the C-shaped ring to prevent flame diffusion and smoke flow.

The secondary feature of the present invention is that one end of the first side wall and the second side wall is provided with a fixed end, and the inner space of the C-shaped ring is covered on the fixed end; the first side wall and the second side wall are inclined and bent The rear fixed end is at the same height on the surface of the fire-resistant rolling door box; or the first side wall and the second side wall are inclined and bent, and the fixed end is a high and low height overlapping opening in the fire roll. On the surface of the door box; one end of the first side wall and the second side wall can be connected to one end piece, and the end piece is connected with the end piece by a screwing or riveting method to the joint hole opened at one end of the first side wall and the second side wall. , And the end piece is assembled and fixed to form an opening.

Please refer to the perspective view of the preferred embodiment of the present invention shown in FIG. 2, wherein the fireproof rolling door 1 of the present invention has a fireproof rolling door box 11 as in the conventional technology, and one door is provided on each side of the fireproof rolling door box 11. The rail 12 and the fire-resistant rolling door box 11 are provided with a rollable driving device, which is connected to a rotatable reel 3, and the reel 3 winds a fire-resistant rolling screen 4, which is driven by the driving device. Then, it can be controlled to roll up and roll down or roll down, and the fire curtain 4 is provided with a base 9 at the bottom side, so that the fire curtain 4 is supported on the ground when the fire curtain 4 is unfolded to the bottom of the stroke, or when it is rolled to the upper end of the stroke. By positioning.

Please refer to a partial AA ′ sectional view of the first preferred embodiment of the present invention shown in FIG. 3. The fire-resistant rolling door box 11 is viewed from the AA ′ side sectional view of FIG. 2. The box 11 is provided with an opening 113 provided in the fire-resistant rolling screen 4 wound by the reel 3, and the main technical feature of the present invention is that the opening 113 is formed by bending the fire-proof door box 11 inwardly to form a first section. A channel 113 formed by a side wall 111 and a second side wall 112, and a C-shaped ring strip 6 is sleeved on one end edge of the opening 113 formed by the first and second side walls 111 and 112, with a distance between the two C-shaped ring strips 6. That is, the opening 113 is formed. The passage formed by the opening 113 can be used for the fire-resistant rolling screen 4 rolled by the reel 3 to expand downward through the opening 113, and then the driving device is connected from the upper part and extended to the lower base 9.

Referring to FIG. 4 and FIG. 5, the sectional views of part B of the various designs shown in the first preferred embodiment of the present invention can solve the problem of the complicated and high-cost design of the airtight structure of the conventional fire-resistant rolling door box. With air-tightness effect and durability, the present invention has two opposite C-shaped ring strips 6 mounted on the inner end of the opening 113 channel against the surface of the fire-resistant rolling screen 4 rolled up by the top reel 3 downward. Wherein, one end of the first side wall 111 and the second side wall 112 is provided with a fixed end 1111/1121, and the C-shaped ring 6 is inserted into the inner space from the sides of the first side wall 111 and the second side wall 112 during assembly. Covered outside the fixed ends 1111 and 1121, the C-shaped ring strip 6 is mainly made of a metal material with a smooth surface as the main application material.

In the embodiment shown in FIG. 4, the first side wall 111 and the second side wall 112 are designed to form the opening 113 at an oblique bending, and the first side wall 111 and the second side wall 112 are formed after the oblique bending. The fixed end 1111 and 1121 are at the same height on the surface of the fire-resistant rolling door box 11. When a fire occurs, the flame or smoke pressure P is from the C-shaped ring 6 provided at the fixed end 1111 to the C-shaped ring provided at the fixed end 1121. When pressed in 6 directions, the surface of the compressed fire curtain 4 'is pressed against the end edge of the C-shaped ring 6 provided at the fixed end 1121. At this time, the strong pressure causes the surface of the fire curtain 4' and the C-shaped ring 6 The higher the degree of airtightness, the closer the flame diffusion and the smoke flow can be blocked, and a good airtightness effect can be achieved.

Before the acceptance, in another aspect of the embodiment of FIG. 5, the first side wall 111 and the second side wall 112 are designed to form the opening 113 by oblique bending, wherein the first side wall 114 and the second side wall 115 are obliquely bent. The rear fixed end 1141/1151 is a high-low-height overlapping opening 113 on the surface of the fire-resistant rolling door box 11 so that the fire-proof rolling curtain 4 passes through the high-low overlapping opening 113 and presents an S-shaped passage. When a fire occurs, the flame or smoke pressure P is pressed from the C-shaped ring 6 provided on the fixed end 1111 toward the C-shaped ring 6 provided on the fixed end 1121, and the position of the side of the surface of the pressed fire curtain 4 'is tight. On the edge of the C-shaped ring 6 provided on the fixed end 1141, the position of the other side of the fireproof curtain 4 'below is tightly pressed on the edge of the C-shaped ring 6 provided on the fixed end 1151. At this time, strong pressure pulls The higher the air-tightness between the surface of the fireproof curtain 4 'and the C-shaped ring 6, the more tightly it can block the flame diffusion and smoke flow, and achieve a good air-tight effect.

Please refer to the cross-sectional view of part B of the second preferred embodiment type of the present invention shown in FIG. 6 and FIG. 7. In this type, the first side wall 111/114 and the second side wall 112/115 of the foregoing two modes are mainly one end. Instead, it is connected to one end piece 8. The end piece 8 is made of Teflon and other surface scratch-proof and fire-resistant materials. The end piece 8 is connected to the first side wall 111/114 and the first side wall 111/114 with a joint by means of screwing or riveting. The coupling holes 1112/1122/1142/1152 formed at one end of the second side wall 112/115 are formed, and the end piece 8 is assembled and fixed to form the opening 113 in the two forms as previously described.

To sum up, the present invention adopts the air-tight structure of the fire-resistant rolling door box of the foregoing type. The structural design makes the structure simple and simultaneously has the air-tight effect of fire and smoke insulation. It can also reduce the cost of assembly and materials, and there is no same or similar The previous case was designed first, which complied with the application requirements of the Patent Law, and filed an application for an invention patent in accordance with the law.
