[0007] The door frame assembly includes a fireproof shell, a sliding assembly, and a fireproof airbag. The fireproof shell is fixedly connected to the lower end of the roller storage bin and wrapped around the front and back sides of the fireproof door. One end of the sliding assembly is evenly distributed inside the fireproof shell. The sliding assembly is slidably connected to the curtain sheet assembly. The fireproof airbag is located on both sides of the sliding assembly in the fireproof shell.

[0008] The sealing assembly includes a connecting spring and a fireproof sealing plate. The connecting spring is fixedly connected to the curtain assembly at the lower end of the fire door. The fireproof sealing plate is C-shaped and has a certain elasticity. The fireproof sealing plate is tightly clamped on both sides of the curtain assembly.

[0009] Furthermore: the curtain panel assembly includes a stainless steel outer layer and a fireproof and heat-insulating layer, and the stainless steel outer layer is fixedly connected to both sides of the fireproof and heat-insulating layer.

[0010] Furthermore: the sliding assembly includes a connecting piece and a sliding roller, the connecting piece is fixedly connected to the inner side of the fireproof shell, and the sliding roller is rotatably connected to one end of the connecting piece.

[0011] Furthermore: both ends of the fireproof and heat-insulating layer are provided with sliding grooves adapted to the sliding rollers.

[0012] Furthermore: both ends of the lower side of the fireproof sealing plate are provided with rounded corners.

[0013] Furthermore: the outer side of the door frame assembly on one side is electrically connected to a control panel, and buttons and an emergency stop switch are provided on the side of the control panel.

[0014] Furthermore: handles are fixedly connected to both sides of the sealing component.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] This patent sets a fire-resistant airbag in the door frame assembly to enhance the sealing of the side of the fire door without affecting the opening and closing of the fire door. By setting up a sealing assembly and connecting the spring, the fireproof sealing plate and the bottom surface are tightly fitted, thereby enhancing the sealing of the bottom surface of the fire door, effectively reducing flames and smoke, and preventing flames and smoke from threatening people's lives.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] Combined with attachment Figure 1-4 The utility model provides a fireproof rolling shutter door, including a roller retracting bin 1 and a fire door 2. The fire door 2 is composed of a plurality of curtain blade assemblies 3. The curtain blade assembly 3 is rotatably connected and movably connected to the lower end of the roller retracting bin 1 through a hinge. The lower end of the roller retracting bin 1 is located on both sides of the fire door 2 and is fixedly connected to a door frame assembly 4. The lower end of the fire door 2 is provided with a sealing assembly 5; the door frame assembly 4 includes a fireproof shell 41, a sliding assembly 42, and a fireproof airbag 43. The fireproof shell 41 is fixedly connected to the lower end of the roller retracting bin 1 and wrapped around the front and back sides of the fire door 2. One end of the sliding assembly 42 is evenly distributed on the inner side of the fireproof shell 41. The sliding assembly 42 is slidably connected to the curtain blade assembly 3. The fireproof airbag 43 is located on both sides of the sliding assembly 42 in the fireproof shell 41. On the other hand, the sliding component 42 increases the smoothness of the curtain assembly 3 in the process of moving up and down in the fireproof shell 41. The fire-resistant airbag 43 can fit tightly with the fire door 2 and the fireproof shell 41, ensuring the sealing on both sides of the fire door 2. The sealing component 5 includes a connecting spring 51 and a fireproof sealing plate 52. The connecting spring 51 is fixedly connected to the bottom of the curtain assembly 3 at the lower end of the fire door 2. The fireproof sealing plate 52 is C-shaped and has a certain elasticity. The fireproof sealing plate 52 is tightly clamped on both sides of the curtain assembly 3. After the fire door 2 is closed, the fireproof sealing plate 52 at the lower end of the fire door 2 is affected by the connecting spring 51 to fill the gap between the ground and the fire door 2, thereby ensuring the sealing between the lower end of the fire door 2 and the ground, and forming an effective fire barrier.

[0027] Example 2

[0028] Combined with the attached drawings

[0029] On the basis of embodiment 1, the curtain assembly 3 includes a stainless steel outer layer 31 and a fireproof insulation layer 32. The stainless steel outer layer 31 is fixedly connected to both sides of the fireproof insulation layer 32, which effectively enhances the strength and thermal insulation performance of the fire door 2. The sliding assembly 42 includes a connecting member 44 and a sliding roller 45. The connecting member 44 is fixedly connected to the inner side of the fireproof shell 41. The sliding roller 45 is rotatably connected to one end of the connecting member 44. The two ends of the fireproof insulation layer 32 are provided with a slide groove 33 adapted to the sliding roller 45, which increases the curtain assembly 3. The smoothness of sliding makes it easy for the curtain assembly 3 to slide inside the fireproof shell 41. The lower ends of the fireproof sealing plate 52 are provided with rounded corners, so that the fireproof sealing plate 52 can squeeze the fireproof airbag 43 more smoothly during the descent process, avoiding the fireproof airbag 43 blocking the descent of the fireproof sealing plate 52. The outer side of the door frame assembly 4 on one side is electrically connected to the control panel 6, and the side of the control panel 6 is provided with a button 61 and an emergency stop switch 62. Handles 53 are fixedly connected on both sides of the sealing assembly 5 for controlling the fireproof rolling shutter door.

[0030] The working principle of this application is: when encountering a fire, the fire door 2 is controlled to descend, and the sliding assembly 42 increases the smoothness of the curtain assembly 3 in the process of moving up and down in the fire shell 41. The rounded corners of the fireproof sealing plate 52 enable it to squeeze the fireproof airbag 43 more smoothly during the descent process. After the fire door 2 is closed, the fireproof airbag 43 fits with the fire door 2 and the fire shell 41, ensuring the sealing of both sides of the fire door 2. The fireproof sealing plate 52 at the lower end of the fire door 2 is acted upon by the connecting spring 51 to fill the gap between the ground and the fire door 2, ensuring the sealing between the lower end of the fire door 2 and the ground, forming an effective fire barrier to prevent the spread of fire and smoke.

[0031] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
