DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] In order to facilitate the addition of auxiliary sealing mechanisms, deformation is used to reduce the gap between the rolling door and the door frame, thereby improving the use effect, such as Figure 1-3 As shown, a smoke-proof fire-proof rolling shutter door of the utility model comprises a rolling bracket 1, a door frame assembly 2 and a positioning assembly 4, wherein the bottom of the rolling bracket 1 is connected to the door frame assembly 2 by bolts, a rolling shutter door assembly 3 is arranged between the door frame assemblies 2 in the rolling bracket 1, and a positioning assembly 4 is arranged between the door frame assemblies 2 and at the bottom of the rolling shutter door assembly 3;

[0032] The door frame assembly 2 includes a door frame 201 , a surface of the door frame 201 is provided with a groove 202 , a U-shaped sheath 203 is slidably connected in the groove 202 , and an inflatable cushion 205 is glued to the inner side of the U-shaped sheath 203 in the groove 202 .

[0033] When in use, the deformation caused by inflation can be utilized through the inflatable cushion 205, the U-shaped sheath 203 and the groove 202 to reduce the gap between the rolling door and the door frame 201, improve the sealing of the rolling door, and thus improve the fire and smoke isolation effect of the rolling door.

[0034] The outer surface of the door frame 201 is connected with an air nozzle via threads, and the air outlet end of the air nozzle is connected to the inflatable cushion 205 via a hose.

[0035] The surfaces of the door frame 201, the U-shaped sheath 203, the inflatable cushion 205, the rolling door assembly 3 and the positioning assembly 4 are all coated with fire retardant paint.

[0036] In order to improve the flexibility of rolling door opening, for example, Figure 1 , Figure 3 As shown, the utility model also includes that the positioning assembly 4 includes a fixed base 401, both sides of the fixed base 401 are sleeved and connected to the positioning block 402, and a compression spring 403 is installed on the inner side of the positioning block 402 in the fixed base 401 through a spring seat.

[0037] When in use, by fixing the base 401, the positioning block 402 and the compression spring 403, the elastic force can be used to push and form an auxiliary limiting mechanism. When the driving mechanism is damaged, a manual opening mechanism can be added to improve the flexibility of the rolling door.

[0038] For example, Figure 2 As shown, the utility model also includes that both sides of the U-shaped sleeve 203 are connected with protrusions 204 by bolts, and the U-shaped sleeve 203 is slidably connected to the groove 202 through the protrusions 204 on both sides, and a return spring 206 is installed in the groove 202 on the outside of the protrusion 204 through a card slot, and a slot 207 is opened on the surface of the door frame 201.

[0039] When in use, the protrusion 204 and the return spring 206 facilitate the use of elastic force to push the U-shaped sheath 203 back to perform a return action after the rolling door is opened, thereby avoiding affecting normal use.

[0040] For example, Figure 1 , Figure 5 As shown, the utility model also includes that one side of the winding bracket 1 is connected to an exhaust fan 101 by bolts, and the air outlet end of the exhaust fan 101 is located outside the winding bracket 1, and the outer surface of the winding bracket 1 is provided with an air outlet 102 corresponding to the exhaust fan 101.

[0041] When in use, the exhaust fan 101 and the air outlet 102 facilitate auxiliary smoke exhaust processing in the rolling bracket 1, further improving the smoke isolation and fire prevention effect of the rolling shutter door.

[0042] For example, Figure 3 As shown, the utility model further includes that a slot 404 is provided on the top of the fixed base 401 , and both sides of the slot 404 are connected with electromagnets 405 through bolts.

[0043] When in use, the slot 404 and the electromagnet 405 are used to facilitate the magnetic attraction generated by power-on to perform auxiliary limiting and fixing processing on the rolling shutter door assembly 3, thereby improving the stability of use. A second inflatable cushion is connected to the slot 404 by gluing.

[0044] For example, Figure 4 As shown, the utility model also includes that the rolling door assembly 3 includes a curtain piece 301, and the bottom of the curtain piece 301 is connected to a counterweight block 302 by bolts.

[0045] When in use, the curtain piece 301 and the counterweight block 302 are used to form a rolling shutter door, and the counterweight block 302 is made of iron.

[0046] For example, Figure 1 , Figure 5 As shown, the utility model also includes that a rolling curtain shaft 5 is installed in the winding bracket 1 through a bearing, a driving motor 6 is connected to the outer side of the winding bracket 1 through bolts, and the driving motor 6 is connected to the rolling curtain shaft 5 through a driving shaft.

[0047] When in use, the rolling shutter shaft 5 is driven by the driving motor 6 to rotate to perform the rolling and lowering actions of the rolling shutter door.

[0048] When the utility model is in use, the driving motor 6 is manually turned on to drive the rolling shutter shaft 5 to rotate, driving the rolling shutter door to retract and release, thereby realizing the opening and closing operation of the rolling shutter door. When the counterweight block 302 is inserted into the card slot 404, the electromagnet 405 is manually turned on, and the magnetic attraction generated by the electromagnet 405 is used to perform auxiliary limit fixing processing on the rolling shutter door.

[0049] After the rolling door is closed, an external air pump device can be connected through an air nozzle to inflate the inflatable cushion 205. The deformation caused by the inflation of the inflatable cushion 205 can push the U-shaped sheath 203 to slide outward, so that the outer side of the curtain piece 301 is stuck in the U-shaped sheath 203, thereby reducing the gap between the rolling door and the door frame 201, improving the sealing performance of the rolling door, and improving the smoke and fire protection effect and quality of the rolling door.

[0050] When the driving mechanism of the rolling door is damaged, the positioning block 402 can be manually pushed back into the fixed base 401 from the slot 207 on the outside of the door frame to separate the fixed base 401 from the door frame 201, and then the fixed base 401 can be manually lifted, and the elastic force of the compression spring 403 can be used to push the positioning block 402 to slide into the top slot 207 to complete the manual opening action. The added manual opening method can greatly improve the flexibility of the rolling door, avoid the damage of the driving mechanism affecting the work, and achieve the effect of temporary use.

[0051] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model.
