DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0021] Combination Figure 1-Figure 5 The utility model discloses a sealing curtain for an adaptive window, comprising a flexible curtain body 1 and a driving assembly 2. The flexible curtain body 1 is made of aramid fiber, has extremely high tensile strength and elastic modulus, and can be stretched to adapt to sealing windows 5 of different sizes. Expansion strips 11 are arranged around the flexible curtain body 1. The expansion strips 11 are filled with expandable graphite. When encountering high temperature, the expandable graphite can expand rapidly to form a good sealing layer. A limiting assembly 3 is sleeved on the expansion strip 11.

[0022] In this embodiment, the driving component 2 includes a transverse telescopic frame 21, a longitudinal telescopic frame 22 and a driving motor group 23. The transverse telescopic frame 21 and the longitudinal telescopic frame 22 are distributed at right angles, and the driving motor group 23 is provided at one end of the transverse telescopic frame 21 and the longitudinal telescopic frame 22 close to each other. The driving motor group 23 controls the transverse telescopic frame 21 and the longitudinal telescopic frame 22 to extend or shorten. The transverse telescopic frame 21 and the longitudinal telescopic frame 22 are respectively movably connected to the limit components 3 at the corresponding positions. When the transverse telescopic frame 21 and the longitudinal telescopic frame 22 are extended or retracted, the limit components 3 are controlled to extend or retract, and then the transverse telescopic frame 21 drives the flexible curtain body 1 connected thereto to stretch transversely, and the longitudinal telescopic frame 22 controls the flexible curtain body 1 to stretch longitudinally, so that the flexible curtain body 1 can be close to the edge of the sealing window 5 and adapt to the size of the sealing window 5.

[0023] In this embodiment, the driving motor group 23 includes at least two micromotors, and the transverse telescopic frame 21 and the longitudinal telescopic frame 22 are respectively connected to a micromotor, and the output end of the micromotor is fixedly connected to a screw rod 231, and a threaded sleeve 232 is sleeved on the screw rod 231. The threaded sleeve 232 is movably connected to a support leg at one end of the transverse telescopic frame 21 or the longitudinal telescopic frame 22 through a rotating shaft. When the micromotor is working, it drives the screw rod 231 to rotate, and the screw rod 231 controls the threaded sleeve 232 to move along the screw rod 231, thereby controlling the extension and retraction of the transverse telescopic frame 21 and the longitudinal telescopic frame 22. The support legs of the transverse telescopic frame 21 and the longitudinal telescopic frame 22 that are close to each other and are not provided with the threaded sleeve 232 at one end are movably connected through the same movable shaft, and the movable shaft is movably connected to the limit assembly 3. During operation, the position of the movable shaft will not move. Accordingly, one end of the limit assembly 3 connected to the movable shaft is fixed, which is equivalent to fixing the position of one corner of the flexible curtain body 1.

[0024] In this embodiment, a control device 4 is provided on one side of the driving motor group 23. A control chip is provided in the control device 4 to set the working procedures of the driving motor group 23 and the heating resistance wire. The end of the screw rod 231 is connected to the outer wall of the control device 4 through a bracket. The control device 4 is electrically connected to the driving motor group 23. The control device 4 is used to control the operation of the driving motor group 23 and support the screw rod 231 at the same time.

[0025] In this embodiment, four groups of limit components 3 are provided, and the four groups of limit components 3 are distributed in a rectangular shape. The limit components 3 include an outer plate 31 and an inner slide 32. The outer plate 31 and the inner slide 32 are socketed, and one end of the outer plate 31 or the inner slide 32 or the combination of the outer plate 31 and the inner slide 32 located at the same right angle is fixedly connected to form four right-angle structures. The four groups of limit components 3 can be divided into a right-angle structure in which two outer plates 31 and the inner slide 32 are connected, a right-angle structure connected by one outer plate 31 and a right-angle structure connected by the inner slide 32, one end of the outer plate 31 and the inner slide 32 is fixedly connected, and the top angle position of the right-angle structure is fixedly connected to the right angle of the flexible curtain body 1. When the right-angle structure moves, it can synchronously drive the four corners of the flexible curtain body 1 to move.

[0026] In this embodiment, a slide groove 311 is opened on the inner wall of the outer sleeve 31, and the upper and lower surfaces of the inner slide plate 32 are connected with a slide bar 321 movably connected to the slide groove 311. The slide bar 321 moves in the slide groove 311 to realize the extension and retraction of the limit assembly 3. A clamping plate 312 is provided on the side of the outer sleeve 31 and the inner slide plate 32 close to the flexible curtain body 1. The clamping plate 312 prevents the expansion strip 11 from detaching from the outer sleeve 31 and the inner slide plate 32. The outer sleeve 31 and the inner slide plate 32 are flush with the side away from the flexible curtain body 1, and both are open structures. When the expansion strip 11 expands, it can fit tightly against the window to achieve sealing.

[0027] In this embodiment, heating resistance wires are embedded in the inner walls of the outer plate 31 and the inner slide plate 32. The heating resistance wires are electrically connected to the control device 4. The control device 4 controls the heating of the heating resistance wires. The temperature of the outer plate 31 and the inner slide plate 32 increases, which can control the expansion of the expansion strip 11.

[0028] Working process: install the control device 4 on a corner outside the sealing window 5, so that two groups of limit components 3 are respectively fitted with the inner walls of the sealing window 5, among which the right-angle structure fitted with the inner wall of the sealing window 5 is fitted with a right angle of the sealing window 5, and the control device 4 controls the drive motor group 23 and the heating resistance wire to work, and the horizontal telescopic frame 21 and the longitudinal telescopic frame 22 are extended, driving the limit components 3 to extend, and the flexible curtain body 1 is stretched until the four groups of limit components 3 are completely fitted with the inner wall of the sealing window 5, and the sealing window 5 is blocked by the flexible curtain body 1. At the same time, after the heating resistance wire heats the outer plate 31 and the inner slide plate 32, the expansion strip 11 expands due to the heat, and the expansion strip 11 is pressed against the side wall of the sealing window 5 to prevent the sealing curtain from loosening.

[0029] To sum up: the utility model is a sealing curtain for an adaptive window, and a flexible curtain body 1 is made of aramid fiber, which has extremely high tensile strength and elastic modulus and can adapt to sealing windows 5 of different sizes. At the same time, expansion strips 11 are arranged around the flexible curtain body 1, and the expansion strips 11 are filled with expandable graphite. When encountering high temperature, the expandable graphite can expand rapidly to form a good sealing layer, thereby improving the stability of the sealing curtain. The horizontal telescopic frame 21 and the longitudinal telescopic frame 22 are controlled by the driving motor group 23 to extend and retract, thereby driving the limit assembly 3 to control the flexible curtain body 1 to stretch, so that it can automatically adapt to the sealing needs of the sealing window 5 and is flexible to use.
