[0057] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0058] Specific Implementation Example I:

[0059] This invention provides an embodiment:

[0060] To enhance airtightness, such as Figure 1 A curtain sealing device includes: an air source 1, a support assembly 2, and an expansion member 3; wherein, the support assembly 2 is arranged around the perimeter of the curtain K, and can be arranged on the three sides other than the top; the expansion member 3 is disposed inside the support assembly 2 and connected to the air source 1. Preferably, the curtain K is located between the wall that fixes the support assembly 2 and the expansion member 3. When sealing is required, such as in the event of a fire, the air source 1 inflates the expansion member 3 to increase its volume, thereby pressing the curtain K to form a sealing structure.

[0061] Specifically, this embodiment provides a specific implementation structure for the support component 2:

[0062] The support component 2, such as Figure 23. Includes: a support body 201 and a connector 202; wherein, the support assembly 2 can be an integrally formed aluminum alloy profile; the connector 202 can be fixed to one side of the support body 201 by bolts or other fasteners for fixing to the external wall surface; preferably, the support body 201 is provided with a recessed area 2A for placing the expansion member 3; on the one hand, it can limit the expansion member 3, and on the other hand, it can protect the expansion member 3 and prevent it from being damaged and leaking air during use; such as Figure 3 The sealant at points A, B, C, and D is sufficient to meet the sealing requirements for curtain K.

[0063] Meanwhile, in the above-described implementation structure, only the expansion member 3 is used as a sealing element to seal the curtain K. However, if the external fire lasts for a long time or the smoke temperature is very high, simply using the expansion member 3 as a sealing element may also cause smoke leakage problems. Based on this, this embodiment also provides another specific implementation structure for the support component 2:

[0064] The support component 2, such as Figure 4 It includes: a support body 201, a connector 202, and a moving mechanism 203; wherein, the connector 202 is disposed on one side of the support body 201 for fixing to the outside; the moving mechanism 203 is disposed on the side of the support body 201 near the curtain K for moving towards the curtain K when the volume of the expansion member 3 increases.

[0065] In this embodiment, due to the addition of the movable mechanism 203, when the volume of the expansion member 3 increases, the movable mechanism 203 is driven to move towards the curtain K, forming a secondary sealing structure composed of the expansion member 3 and the movable mechanism 203, which further improves the sealing effect.

[0066] Specifically, the activity mechanism 203, such as Figure 5 The system includes: a guide member 2031, a reset member 2032, a pressure plate 2033, a movable plate 2034, and a hinge structure 2035; wherein, one end of the guide member 2031 is disposed on the side of the support body 201 facing the curtain K; the reset member 2032 is coaxially disposed on the guide member 2031; the pressure plate 2033 is disposed on the end of the reset member 2032 facing the curtain K; the movable plate 2034 is movably disposed on the pressure plate 2033 and contacts the expansion member 3; the hinge structure 2035 is disposed between the movable plate 2034 and the pressure plate 2033, and is used to drive the movable plate 2034 to move towards the curtain K through the pressure plate 2033;

[0067] During use, the addition of the hinge structure 2035 and the reset component 2032 causes the movable plate 2034 to compress the hinge structure 2035 under the action of the expansion component 3, thereby moving the pressure plate 2033 towards the curtain K to form a sealing structure. Moreover, the hinge structure 2035 only starts to work when the volume of the expansion component 3 increases to a certain extent. If the external smoke concentration is not high, only the expansion component 3 is needed for sealing, i.e., a primary sealing structure is sufficient. If the external smoke concentration is too high, the expansion component 3 continues to increase, causing the pressure plate 2033 to move towards the curtain K to form a secondary sealing structure, ensuring airtightness.

[0068] Preferred, such as Figure 6 The hinge structure 2035 includes: a first connecting rod 20351, a second connecting rod 20352, a third connecting rod 20353, and a fourth connecting rod 20354; wherein, one end of the second connecting rod 20352 is hinged to one end of the first connecting rod 20351 to form a first connection 1S; one end of the third connecting rod 20353 is connected to one end of the guide member 2031 to form a third connection 3S; one end of the fourth connecting rod 20354 is connected to the other end of the third connecting rod 20353 to form a fourth connection 4S; the first connection 1S is located at one end of the guide member 2031; the fourth connecting rod 20354... A second connection 2S is provided at the other end of the guide member 2031; the other end of the second connecting rod 20352 is connected to the end of the guide member 2031 to form a second connection 2S; the other end of the first connecting rod 20351 is connected to the end of the guide member 2031 to form a sixth connection 6S; the other end of the fourth connecting rod 20354 is connected to the end of the guide member 2031 to form a fifth connection 5S; and the end of the guide member 2031 near the sixth connection 6S serves as a movable end and is connected to the movable plate 2034; the other end of the guide member 2031 is fixed to the support body 201.

[0069] To ensure the direction of movement of the movable plate 2034, a first guide structure is provided between the movable plate 2034 and the pressure plate 2033; a second guide structure is provided between the pressure plate 2033 and the support body 201. In this embodiment, both the first guide structure and the second guide structure can be guide structures with protrusions and guide grooves. For example, the bottom of the movable plate 2034 is provided with a protrusion, and the pressure plate 2033 is provided with a groove corresponding to the protrusion, thereby achieving guidance.

[0070] Preferred, such as Figure 7The guide member 2031 includes a first guide portion 20311 and a second guide portion 20312; wherein the first guide portion 20311 and the second guide portion 20312 are sleeve mechanisms; further, the ends of the first guide portion 20311 and the second guide portion 20312 are provided with annular protrusions to limit the reset member 2032; in specific use, the two ends of the reset member 2032 can be fixed on the annular protrusions of the first guide portion 20311 and the second guide portion 20312 respectively.

[0071] Preferably, the pressure plate 2033 is provided with a fireproof and flame-retardant layer on the side facing the curtain K to prevent combustion and fire caused by excessive temperature.

[0072] It needs to be clarified that: Figure 1-4 The S in the diagram represents the wall where the window is located.

[0073] Specific Implementation Example II:

[0074] In specific embodiment I, the support body 201 and the wall S clamp the curtain K, thus forming a sealed structure. However, in actual use, the condition of the wall surface varies. If there is damage or poor flatness, it will affect the sealing effect of the technical solution described in specific embodiment I.

[0075] Based on this, such as Figure 8-9 The present invention also discloses two embodiments:

[0076] In this embodiment, the support body 201 is a profile, such as an aluminum profile; the curtain K is located in the middle of the support body 201, which is a profile; the structure of other parts is the same as in specific embodiment I.

[0077] In specific construction, such as Figure 8 and Figure 9 Two different installation methods are disclosed, which can be adjusted according to the structure near the specific window for easy installation. In addition, to improve reliability, an inflatable fireproof cotton layer P is provided on the side of the movable plate 2034 facing the curtain 4 so that the inflatable fireproof cotton layer P can provide a final seal in case of excessive temperature. It should be noted that, similarly, for specific embodiment I, those skilled in the art can also set the inflatable fireproof cotton layer P as needed, which is not described in the attached drawings.

[0078] Specific Implementation Example III:

[0079] The present invention also provides an embodiment:

[0081] It should be clarified that: control unit 4 can be a microcontroller, PLC or other programmable intelligent unit; expansion component 3 can be a Ф12 pressure tube.

[0082] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
