Under the action of the sealing assembly, the soundproof and fireproof plastic-steel door and window does not squeeze and fix the plurality of glasses, and can separate the glass from the plastic-steel door and window body. At this time, a new glass is inserted into the inside of the plastic-steel door and window body, and then the glass is initially fixed by the mounting seat, and the above-mentioned reverse movement is performed, so that the two fixing frames squeeze the sealing block, thereby fixing the glass, and at the same time, under the squeezing of the sealing block, it can effectively achieve a sealing effect.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 5 A plastic steel fire-resistant window with good sealing performance comprises a window frame 1, an outer window frame 2 and an inner window frame 3, the outer window frame 2 and the inner window frame 3 are respectively slidably mounted in the window frame 1, and a sealing component is installed at the alignment position of the outer window frame 2 and the inner window frame 3;

[0023] The sealing assembly includes a sealing groove 4, a movable opening 5, a movable plate 6, a sealing strip 7 and a handle 8. The sealing groove 4 is opened on the surface adjacent to the outer window frame 2 and the inner window frame 3. The movable opening 5 is opened on the inner window frame 3. The movable opening 5 is aligned with the sealing groove 4. The movable plate 6 is slidably installed in the movable opening 5. The sealing strip 7 is fixedly installed on the movable plate 6. The shape of the sealing strip 7 matches the sealing groove 4. The handle 8 is fixedly installed on the movable plate 6 and is located on the back of the sealing strip 7.

[0024] The movable opening 5 includes a limiting front section 51, a movable section 52 and a limiting rear section 53. The movable plate 6 is slidably installed in the movable section 52. The width of the limiting front section 51 is the same as the width of the sealing groove 4. The width of the movable section 52 is larger than the width of the limiting front section 51. The width of the limiting rear section 53 is smaller than the width of the movable section 52. The limiting front section 51 and the limiting rear section 53 behind the limiting front section 51 enable the movable plate 6 to move only in the movable section 52.

[0025] A magnetic attraction component is installed on the movable plate 6, and the magnetic attraction component fixes the position of the movable plate 6. The movable plate 6 is stabilized at a corresponding position through the suction force of the magnetic attraction component on the movable plate 6;

[0026] The magnetic attraction component includes a first magnetic attraction strip 9 and a second magnetic attraction strip 10. The first magnetic attraction strip 9 is fixedly installed on the four corners of the moving section 52, and mounting grooves are provided on the four corners of the moving plate 6. The second magnetic attraction strip 10 is fixedly installed in the mounting groove. The first magnetic attraction strip 9 and the second magnetic attraction strip 10 are magnetically attracted. When the sealing strip 7 is pushed into the sealing groove 4, the second magnetic attraction strip 10 at the end of the sealing strip 7 on the moving plate 6 is magnetically attracted to the first magnetic attraction strip 9 at the edge of the limiting front section 51. When the sealing strip 7 is pulled out, the second magnetic attraction strip 10 near the end of the handle 8 is magnetically attracted to the first magnetic attraction strip 9 at the limiting rear section 53.

[0027] Two slots 11 are provided on the handle 8, and the spacing between the slots 11 is equal to the movable distance of the movable plate 6. When the sealing strip 7 is pushed into the sealing groove 4, the limiting piece 12 is stuck in one of the slots 11, and when the sealing strip 7 is pulled out, the limiting piece 12 is stuck in the other slot 11;

[0028] A limit plate 12 is rotatably installed on the inner window frame 3, and the limit plate 12 is clamped in the clamping groove 11. The limit plate 12 fixes the handle 8 and the movable plate 6 to prevent the magnetic attraction force generated by the first magnetic strips 9 at both ends to the second magnetic strips 10 from causing the movable plate 6 to move.

[0029] In the utility model, after the window is pushed to be closed, the handle 8 is pushed to push the movable plate 6 toward the inner and outer window frames 2, thereby pushing the sealing strip 7 out of the movable opening 5, so that the sealing strip 7 is inserted into the sealing groove 4, and the sealing strip 7 fills the gap between the two windows, thereby improving the sealing between the two windows after the window is closed.

[0030] In general, regarding the technical problem: for sliding windows, there is a gap between the outer frames of the two windows after they slide closed, resulting in poor sealing; a technical solution is adopted: a sealing component is set between the two windows; because the implementation process of the technical solution is: after pushing the window to close, push the handle 8 to push the movable plate 6 toward the inner and outer window frames 2, thereby pushing the sealing strip 7 out of the movable opening 5, so that the sealing strip 7 is inserted into the sealing groove 4, and the sealing strip 7 fills the gap between the two windows; this will inevitably solve the technical problem, and the technical effect achieved is: the sealing between the two windows is improved after the window is closed.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
