Description

Technical Field

[0001] The utility model relates to the technical field of door and window structures, in particular to an inward-opening window structure with high sealing performance. Background Art

[0002] Doors and windows generally refer to various windows or doors arranged at openings such as windows or entrances to separate the interior and exterior of a building. Door frames and window frames mostly adopt frames made of pressed metal profiles or non-metal profiles. Generally, doors and windows with only single-layer glass have poor heat insulation and sound insulation performance. Therefore, most of the doors and windows constructed at the entrances of offices, schools, hospitals or merchants with certain requirements for heat insulation or sound insulation use double-layer glass.

[0003] An inward-opening window is a window design in which the window can be opened inward. This design provides various benefits, including safety, space saving, convenient cleaning, energy saving and good sound insulation. This design not only facilitates cleaning the interior and exterior of the window, but also, due to their good sealing performance, can effectively reduce the noise between the interior and the exterior, providing a relatively quiet and comfortable living environment for the occupants.

[0004] Such as Figure 1-2 For the existing inward-opening window products in the market as shown, a special-shaped heat insulation strip is passed through the glass fan profile, and the sealing and closing are achieved by the collision between the special-shaped heat insulation strip and the rubber strip of the window frame profile. However, the actual overlapping amount is small, and the overlapping amount cannot achieve a good sealing effect, resulting in a reduction in the sealing performance of the whole window. Summary of the Invention

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an inward-opening window structure with high sealing performance.

[0006] To achieve the above purpose, the technical solution provided by the utility model is: an inward-opening window structure with high sealing performance, including a frame profile and a glass fan profile installed with the frame profile. The glass fan profile rotates inward relative to the frame profile. The frame profile includes an inner frame profile, an outer frame profile, a heat insulation strip I clamped therebetween, and a sealing rubber strip I installed on the heat insulation strip I. The sealing rubber strip I is formed with a plug post I inserted into the heat insulation strip I and an L-shaped overlapping portion I extending towards the glass fan profile. The glass fan profile includes an inner glass fan profile, an outer glass fan profile and a heat insulation strip II. The glass fan profile further includes a sealing rubber strip II installed on the heat insulation strip II. The sealing rubber strip II is formed with a plug post II connected to the heat insulation strip II and an overlapping portion II contacting the L-shaped overlapping portion I. The overlapping portion II is superposed at the notch of the L-shaped overlapping portion I to form a sealing portion.

[0007] Preferably, the L-shaped lapping part I includes a base and an extension part extending from the base. The extension part contacts the lapping part II, and the height of the extension part covers the height of the lapping part II on the cross-sectional plane.

[0008] Preferably, the L-shaped lapping part I and the lapping part II are integrally vulcanized and welded rubber strips.

[0009] Preferably, a baffle for supporting the side of the lapping part II away from the L-shaped lapping part I is formed on the inner side of the inner profile of the glass sash.

[0010] Preferably, the heat insulation strip II includes an outer heat insulation plate II and an inner heat insulation plate II integrally combined with it. A slot II for inserting and sleeving the plug post II is formed on the inner heat insulation plate II.

[0011] Furthermore, reinforcing strips II are formed between the outer heat insulation plate II and the inner heat insulation plate II and cross each other.

[0012] Preferably, the heat insulation strip I includes an outer heat insulation plate I and an inner heat insulation plate I integrally combined with it. A slot I for inserting and sleeving the plug post I is formed on the inner heat insulation plate I.

[0013] Furthermore, reinforcing strips I are formed between the outer heat insulation plate I and the inner heat insulation plate I and cross each other.

[0014] Preferably, it further includes a screen window profile installed on the frame profile. The screen window profile includes an outer screen window profile and an inner screen window profile. The screen window profile rotates inwards relative to the frame profile, and the screen window profile and the glass sash profile form a double-inside-opening window structure.

[0015] Compared with the prior art, the overlapping amount is increased by installing two overlapping sealing rubber strips between the frame profile and the glass sash profile. The higher the overlapping amount, the better the airtightness, the better the watertightness, and the better the sound insulation performance; both of the two sealing rubber strips are integrally vulcanized and welded rubber strips, further improving the sealing performance.

[0020] The present utility model will be further described below in conjunction with specific embodiments: Embodiment 1

[0021] See the attached Figure 3-4 As shown, an inward-opening window structure with high sealing performance. Whether it is a single inward-opening window, including a frame profile 1 and a glass sash profile 2 installed on the frame profile 1, or a double inward-opening window product, it also includes a screen window profile 8 installed on the frame profile 1. The glass sash profile 2 and the screen window profile 8 rotate inward relative to the frame profile 1. The frame profile 1 includes a frame inner profile 11, a frame outer profile 12, a heat insulation strip I 3 clamped therebetween, and a sealing strip I 4 installed on the heat insulation strip I 3. The sealing strip I 4 is formed with a plug post I 42 inserted into the heat insulation strip I 3 and an L-shaped overlapping portion I 41 extending towards the glass sash profile 2. The glass sash profile 2 includes a glass sash inner profile 21, a glass sash outer profile 22, and a heat insulation strip II 5. A soundproof glass is installed between the glass sash inner profile 21 and the glass sash outer profile 22. The screen window profile 8 includes a screen window outer profile 81 and a screen window inner profile 82. A screen is installed between the screen window outer profile 81 and the screen window inner profile 82. As Figure 1-2 shown, for existing single or double inward-opening window products on the market, the heat insulation strip II 5 is an irregular heat insulation strip inserted between the glass sash outer profile 22 and the glass sash inner profile 21. Sealing closure is achieved by the collision between the irregular heat insulation strip and the sealing strip I 4. However, the actual overlapping amount is small, and the overlapping amount cannot achieve a good sealing effect, resulting in a reduction in the sealing performance of the entire window.

[0022] Therefore, in order to increase the overlapping amount and enhance the sealing performance, the glass sash profile 2 further includes a sealing strip II 6 installed on the heat insulation strip II 5. The sealing strip II 6 is formed with a plug post II 62 connected to the heat insulation strip II 5 and an overlapping portion II 61 in contact with the L-shaped overlapping portion I 41. The overlapping portion II 61 overlaps at the notch of the L-shaped overlapping portion I 41 to form a sealing portion 7. Both the L-shaped overlapping portion I 41 and the overlapping portion II 61 are integrally vulcanized and welded rubber strips, further improving the sealing performance.

[0023] Specifically, the L-shaped overlapping portion I 41 includes a base and an extension portion 411 extending from the base. The extension portion 411 is in contact with the overlapping portion II 61. The height H of the extension portion 411 covers the height of the overlapping portion II 61 on the cross-sectional horizontal plane, so that the overlapping amount of the overlapping portion II 61 and the extension portion 411 of the L-shaped overlapping portion I 41 is high. Embodiment 2

[0024] The difference from Embodiment 1 is that: when the glass sash profile 2 collides with the frame profile 1 during closing, the sealing strip II 6 and the sealing strip I 4 will collide with each other. In order to extend the service life of the sealing strip II 6 installed on the heat insulation strip II 5, a baffle 211 is formed on the inner side of the inner profile 21 of the glass sash to support the side of the overlapping part II 61 away from the L-shaped overlapping part I 41. Whenever the overlapping part II 61 overlaps and collides with the L-shaped overlapping part I 41, the side of the overlapping part II 61 away from the L-shaped overlapping part I 41 will be supported on the baffle 211, so that the impact on the sealing strip II 6 is reduced. Embodiment 3

[0025] The difference from Embodiment 1 is that: the heat insulation strip II 5 includes an outer heat insulation plate II 51 and an inner heat insulation plate II 52 integrally formed therewith. A slot II for inserting the plug II 62 is formed on the inner heat insulation plate II 52, and reinforcing strips II 53 are formed between the outer heat insulation plate II 51 and the inner heat insulation plate II 52 and cross each other.

[0026] In the prior art, the heat insulation strips between the outer frame profile 12 and the inner frame profile 11 and between the outer glass sash profile 22 and the inner glass sash profile 21 are generally composed of an outer heat insulation plate and an inner heat insulation plate. The outer heat insulation plate and the inner heat insulation plate are two different components respectively. The inner heat insulation plate can also be formed into a special-shaped heat insulation strip to achieve a small amount of overlap with the L-shaped overlapping part II 41.

[0027] The heat insulation strip II 5 in the present application not only integrally forms the outer heat insulation plate II 51 and the inner heat insulation plate II 52, but also has reinforcing strips II 53 formed between them and crossing each other to enhance the structural strength of the heat insulation strip II 5. Moreover, it can also form several independent cavities inside the heat insulation strip II 5 to slow down the heat transfer of air and enhance the heat insulation effect.

[0028] Similarly, the heat insulation strip I 3 includes an outer heat insulation plate I 31 and an inner heat insulation plate I 32 integrally formed therewith. A slot I for inserting the plug I 42 is formed on the inner heat insulation plate I 32, and reinforcing strips I 33 are formed between the outer heat insulation plate I 31 and the inner heat insulation plate I 32 and cross each other, achieving the same effect as the heat insulation strip II 5.
