DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0025] See also Figures 1 to 4 , provided by an embodiment of the utility model, is a high airtightness heat-insulating inward-opening window, comprising an outer frame 1, a middle stile 2 and a window sash 3, wherein the outer frame 1, the middle stile 2 and the window sash 3 are respectively covered by a thermal insulation strip 101, and the thermal insulation strip 101 is filled with an outer frame heat-insulating foam 102;

[0026] A sealing strip A201 is provided on the outdoor side of the middle muntin 2 and the window sash 3, a sealing strip B202 is provided in the middle of the middle muntin 2 and the window sash 3, and a sealing strip C203 is provided on the indoor side of the middle muntin 2 and the window sash 3.

[0027] Specifically, sealing strip A is a single-arm structure with a water-shedding effect; sealing strip B is a multi-cavity structure design to increase the thermal insulation performance of the window and block heat convection, and the overlapping part with the fan is a duckbill structure to increase the compression deformation between the frame and the fan; sealing strip C is a composite foaming structure, in which the part pressed into the groove is a hard structure, and the surface part is a foamed part. The foamed material can increase the deformation of the strip between the frame and the fan.

[0028] Specifically, a drainage isobaric chamber 304 is formed between the sealing strip A201 and the sealing strip B202, and a heat preservation chamber 305 is formed between the sealing strip B202 and the sealing strip C203.

[0029] Specifically, the flange length A between the middle stile 2 and its outer frame is matched with the overlap amount a1 between the sealing strip B202 and the window sash 3. The purpose of this setting is to increase the airtightness of the window sash. The value of A is 25-28.5mm, and the value of a1 is 3-4.5mm. The value of A of general doors and windows is about 20-22mm, and the value of a1 is about 2mm. When there is a deviation in the left-right or up-and-down overlap between the sash and the frame, the airtightness of the inward-opening window cannot be guaranteed.

[0030] Specifically, a sash support 301 for fixing the sash glass is provided in the window sash 3 , and the frame at the connection between the sash glass and the window sash 3 is filled with sash glass thermal insulation foam 302 .

[0031] Specifically, the sash glass is connected to the window sash 3 via a sash glass adhesive strip 306 on the outdoor side, and the sash glass is connected to the sash buckle strip 303 via a glass fixing adhesive strip 307 on the indoor side. The connection between the sash buckle strip 303 and the window sash 3 is filled with a foam adhesive strip.

[0032] Specifically, a glass fixing support 103 for fixing the fixed glass is provided inside the outer frame 1, and a glass fixing adhesive strip B108 is provided at the connection between the outer side of the fixed glass and the outer frame 1.

[0033] Specifically, a glass fixing adhesive strip A105 is provided at the connection between the inner side of the fixing glass and the frame buckle strip 106 , and a buckle strip foam adhesive strip 107 is filled at the connection between the frame buckle strip 106 and the outer frame 1 .

[0034] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific frame buckle strips 106 and sash buckle strips 303 described in the above embodiments. The frame buckle strips 106 and sash buckle strips 303 are designed as closed cavity structures to improve the stability of glass installation and reduce heat transfer and convection.

[0035] Specifically, there is a step deviation X between the fixed pressure line of the frame buckle strip 106 and the outer frame. The purpose of this setting is to avoid the problem of too wide visible surface of the indoor and outdoor frame structure; the step deviation X is 2-3mm.

[0036] Specifically, the window sash 3 is rotatably connected with a handle 308, and the handle 308 is engaged with the slot on the middle mullion 2 through its latch. The purpose of this arrangement is to tightly connect the window sash 3 and the middle mullion 2 through the handle 308 to prevent the window sash 3 from opening without external force.

[0037] In the embodiment of the utility model, the relevant technicians will respectively overlap the outer frame 1, the middle mullion 2, and the window sash 3 through the broken bridge strip 101 during installation, and fill the outer frame insulation foam 102 in the cavity of the broken bridge strip 101, and fill the solid glass insulation foam 104 and the fan glass insulation foam 302 on the frames around the solid glass and the fan glass, and at the same time, the solid glass and the fan glass are respectively supported and inserted into the solid glass support 103 and the fan glass support 301, and the insulation foam material is disconnected and filled at the installation place of the solid glass support 103 and the fan glass support 301 to further increase the airtightness. Effect: This structure adopts a three-seal structure, which divides the internal structure into two parts: a drainage isobaric chamber 304 and an insulation chamber 305. The overlap of the second seal in the middle is particularly important for improving the air tightness of the external window. Therefore, the flange length A between the middle stile 2 and its outer frame is matched with the overlap amount a1 of the sealing strip B202 and the window sash 3 strip to ensure sufficient overlap, thereby ensuring the integrity of the air tightness of the external window. During the operation of the sash, the design of this structure avoids the problem of scratches between the outer half of the window sash 3 profile and the sealing strip B202.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0039] The fixed connection referred to in this application refers to a connection in which a part or component is fixed without any relative movement, which can be divided into detachable connection and non-detachable connection.

[0040] (1) Removable connection: The parts are fixed together by screws, splines, wedge pins, etc. This connection method can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0041] (2) Non-detachable connection: mainly refers to welding, riveting and tenoning. Since forging, sawing or oxygen cutting are required for disassembly during maintenance or replacement, spare parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.) during connection.

[0042] The sliding connection referred to in the present application means that the component can slide along a linear trajectory, and the hinged connection referred to in the present application means that the component can rotate along an axial constraint.

[0043] In some cases, the sliding connection and hinge referred to in the present application may also be damped so that the components have the ability to maintain a desired position.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
