Description

Technical Field

[0001] This utility model relates to the field of thermal break window technology, specifically to a thermal break window with good sealing performance of insulated glass. Background Technology

[0002] Thermally broken aluminum is an upgraded and improved product of aluminum alloy doors and windows. It uses thermal break strips to break the aluminum alloy profile in two, thus achieving thermal insulation and blocking the transfer of heat. In winter, the outdoor temperature will not be conducted into the room through the door and window materials, and the indoor temperature will not be dissipated to the outside through the materials, achieving the effect of energy saving and heat preservation.

[0003] like Figure 1 As shown, the existing thermal break window mainly includes an inner frame 1', an outer frame 2', an inner mullion frame 3', an outer mullion frame 4', glass 5', and a glass bead 6'. The inner frame 1' and the outer frame 2' are connected by a first thermal insulation component 7', and the inner mullion frame 3' and the outer mullion frame 4' are connected by a second thermal insulation component 8'. One side of the glass bead 6' is sealed to the glass 5' with glass glue, and the glass bead 6' is connected to the inner frame 1' and the outer frame 2'. A cavity 9' is formed between the outer frame 2', the inner frame 3' of the mullion, and the outer frame 4' of the mullion. Since it is difficult for workers to fill the cavity with silicone sealant during installation, they only need to apply a layer of silicone sealant to the surface. Therefore, the silicone sealant is only connected to the connection between the glass pressure line and the glass on one side. It is equivalent to the glass pressure line and the glass being directly closed with metal. When the wind pressure is too high, the silicone sealant is squeezed and deformed and is easy to fall off, resulting in water and air leakage in the window. Moreover, the installation is cumbersome and inefficient for workers. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a thermal break window with good airtightness of insulated glass.

[0005] This utility model is achieved through the following technical solution: a thermally broken window with good airtightness, comprising an inner frame, an outer frame, an inner mullion frame, an outer mullion frame, glass, and a glass pressure line. The inner frame and the outer frame are connected by a first thermal insulation component, and the inner mullion frame and the outer mullion frame are connected by a second thermal insulation component. An outer frame fixing plate is integrally connected to the outer surface of the outer frame facing the glass, and an outer mullion fixing plate is integrally connected to the outer surface of the outer mullion facing the glass. The glass is disposed between the glass pressure line and the outer frame fixing plate and the outer mullion fixing plate. A pressure line fixing groove is provided on the outer surface of both the inner frame and the inner mullion frame facing the glass. An inner sealing strip is provided on the side of the glass pressure line facing the glass, and the glass pressure line abuts against the glass through the inner sealing strip. An outer sealing strip is provided between the other side of the glass and the outer frame fixing plate and the outer mullion fixing plate.

[0006] Preferably, the glass pressure line of this utility model includes a pressure line profile body. The outer surface of the pressure line profile body facing the inner frame of the frame material and the inner frame of the mullion are provided with positioning parts adapted to the pressure line fixing groove. The outer surface of the pressure line profile body extends with a retaining edge facing the glass. The retaining edge is provided with an abutting protrusion integrally formed thereon. The abutting protrusion abuts against the outer side of the inner sealing strip.

[0007] Preferably, the inner sealing strip of this utility model includes a hollow strip-shaped strip body. The strip body has a positioning groove for positioning the clamping edge on the side facing the glass pressure line. The strip body has a groove on the side facing the glass, and support portions for abutting against the glass are formed on both sides of the groove.

[0008] Preferably, the side of the abutting protrusion facing the inner sealing strip of this utility model has an anti-slip structure.

[0009] Preferably, the outer surface of the frame fixing plate and the mullion fixing plate of the present invention is provided with a groove for fixing the outer sealing strip on the side facing the glass.

[0010] Compared with the prior art, this utility model has the following advantages and beneficial effects: This utility model provides an inner sealing strip between the glass pressure line and one side of the glass so that the glass pressure line will not directly contact the glass, making it less likely for the sealing strip to deform due to excessive wind pressure, reducing the problem of water and air leakage in the window, improving the window sealing performance, and making the installation simple and efficient for workers.

[0029] Reference Figures 2 to 4As shown, a thermally broken window with good airtightness includes an inner frame 1, an outer frame 2, an inner mullion frame 3, an outer mullion frame 4, glass 5, and glass trim 6. The inner frame 1 and the outer frame 2 are connected by a first thermal insulation member 12, and the inner mullion frame 3 and the outer mullion frame 4 are connected by a second thermal insulation member 34. An outer frame fixing plate 20 is integrally connected to the outer surface of the outer frame 2 facing the glass 5, and a mullion is integrally connected to the outer surface of the outer mullion frame 4 facing the glass 5. The outer frame fixing plate 40 and the glass 5 are located between the glass pressure line 6 and the outer frame fixing plate 20 and the inner frame fixing plate 40 of the mullion. The outer surface of the inner frame 1 of the frame material and the inner frame 3 of the mullion are provided with pressure line fixing grooves 13 on the side facing the glass 5. The glass pressure line 6 is provided with an inner sealing strip 7 on the side facing the glass. The glass pressure line 6 abuts against the glass 5 through the inner sealing strip 7. An outer sealing strip 8 is provided between the other side of the glass 5 and the outer frame fixing plate 20 and the outer frame fixing plate 40 of the mullion.

[0030] To ensure a secure connection between the glass bead and the glass via the inner sealing strip, the structure of the glass bead and the inner sealing strip will be described below.

[0031] The glass pressure line 6 includes a pressure line profile body 60. The outer surface of the pressure line profile body 60 facing the inner frame 1 of the frame material and the inner frame 3 of the mullion is provided with a positioning part 61 that is adapted to the pressure line fixing groove 13. The outer surface of the pressure line profile body 60 facing the glass side extends a retaining edge 62. The retaining edge 62 is provided with an abutting protrusion 63 integrally formed therewith. The abutting protrusion 63 abuts against the outside of the inner sealing strip 7.

[0032] The inner sealing strip 7 includes a hollow strip-shaped strip body 70. The strip body 70 has a positioning groove 71 for positioning along the edge of the clip on the side facing the glass 5 pressure line. The strip body 70 has a slot 72 on the side facing the glass. Support parts 73 for supporting one side of the glass 5 are formed on both sides of the slot 72. The slot 72 and the glass side form a sealed first cavity. Since the strip body 70 is a hollow structure, it forms a second cavity, which can increase the buffering performance of the inner sealing strip. When the wind pressure is too high, the inner sealing strip can improve the buffering effect, ensure that the inner sealing strip is not easily deformed, and has good sealing performance.

[0033] To further improve the stability of the glass pressure line and the inner sealing strip 7, an anti-slip structure 64 is provided on the side of the abutting protrusion 63 facing the inner sealing strip. The anti-slip structure 64 can be corrugated, thereby increasing the support effect of the strong glass pressure line.

[0034] The outer frame fixing plate 20 and the middle mullion outer frame fixing plate 40 have a strip groove 9 for fixing the outer sealing strip 8 on the side of the outer surface facing the glass 5. The outer sealing strip 8 has a corrugated pattern on the side facing the glass to increase the contact area and improve the stability between the outer sealing strip 8 and the glass.

[0035] In addition, both the inner sealing strip 7 and the outer sealing strip 8 are made of EPDM composite foam. Because the strip is made of EPDM composite foam, it expands when exposed to water, thus achieving better sealing performance. Of course, the strip can also be made of other materials, as long as it can achieve the sealing performance; it is not limited to the strip expanding when exposed to water to achieve sealing performance.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
