Description

Technical Field

[0001] This utility model relates to the field of door and window structure technology, and more specifically, to a door and window outer frame structure that improves the performance of the fixed glass part. Background Technology

[0002] Most door and window products on the market currently use a three-layer seal at the frame and sash positions, while the outer frame position for the fixed glass only has two layers of seals. This often only improves the performance of the opening mechanism, neglecting the performance of the fixed parts. Fixed glass accounts for about two-thirds of the total window area, a significant proportion. Therefore, the fixed glass area, as the weakest link in the entire door and window, suffers from lower performance than the opening sash due to a lack of structural optimization, resulting in a reduction in overall window performance.

[0003] In addition, due to the lack of standardized installation practices in the market, many insulated glass units come into direct contact with the frame, resulting in spontaneous breakage of the insulated glass and causing after-sales problems for users. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a door and window frame structure that improves the performance of the fixed glass part.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A window and door frame structure for improving the performance of fixed glass components includes an exterior profile and an interior profile connected by a thermal break strip. A first limiting edge is provided on one side of the exterior profile, and a second limiting edge is provided on one side of the interior profile. Both the first and second limiting edges are located on the same side of the exterior and interior profiles. A double-glazed unit is sandwiched between the first and second limiting edges. A flexible sealing strip is provided on the side of the thermal break strip closest to the double-glazed unit, and the flexible sealing strip abuts against the double-glazed unit.

[0007] Furthermore, in this utility model, the flexible sealing strip includes a connecting strip connected to the heat insulation strip, and a first edge and a second edge spaced apart on the connecting strip. The first edge is located near the outdoor profile, and the second edge is located near the indoor profile. The length of the first edge is greater than the length of the second edge, and both the first edge and the second edge abut against the insulating glass.

[0008] Furthermore, in this utility model, a watertight cavity is formed between the outdoor profile and the first edge; and an airtight cavity is formed between the indoor profile and the second edge.

[0009] Furthermore, in this invention, a water collection trough is also provided inside the aforementioned watertight cavity.

[0010] Furthermore, in this utility model, a groove is provided on the side of the heat insulation strip near the insulating glass, and a locking block adapted to the groove is provided on the side of the connecting strip near the heat insulation strip, and the locking block engages with the groove.

[0011] The beneficial effects of this utility model are:

[0012] 1. The flexible sealing strip installed on the thermal insulation strip divides the area between the first limiting edge and the second limiting edge into two cavities (watertight cavity and airtight cavity). The flexible sealing strip is located in the middle of the insulating glass, which forms an isotherm, blocks the convection of heat, and improves the thermal insulation performance of the fixed position outer frame.

[0013] 2. When rainwater flows into the outdoor profile through the insulated glass, it will be blocked by the flexible sealing strip (first edge), and the rainwater will flow into the watertight cavity, then be collected by the water collection trough, and finally discharged to the outside.

[0014] 3. The added flexible sealing strip in the middle will improve the airtightness of the outer frame at each fixed position, reduce the exchange of indoor and outdoor air, and improve the comfort of living.

[0015] 4. Because the edge strength of insulated glass is relatively low, the edge of insulated glass is prone to spontaneous breakage when it encounters a hard object. Therefore, using flexible sealing strips can make soft contact between the insulated glass and the frame, thereby reducing the risk of spontaneous breakage of the insulated glass.

Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Please see Figure 1 and Figure 2 This utility model provides a technical solution:

[0021] A window / door frame structure for improving the performance of the fixed glass section includes an outdoor profile 102 and an indoor profile 103 connected by a thermal break strip 101. A first limiting edge 201 is integrally formed on one side of the outdoor profile 102, and a second limiting edge 301 is integrally formed on one side of the indoor profile 103. Both the first limiting edge 201 and the second limiting edge 301 are located on the same side of the outdoor profile 102 and the indoor profile 103. An insulated glass unit 401 is sandwiched between the first limiting edge 201 and the second limiting edge 301. To improve the performance of the frame for fixing the glass section, a flexible sealing strip 501 is installed on the side of the thermal break strip 101 near the insulated glass unit 401. After the insulated glass unit 401 is installed, the flexible sealing strip 501 abuts against the insulated glass unit 401.

[0022] Specifically, in this embodiment, the flexible sealing strip 501 includes an integrally formed connecting strip 5011, a first edge 5012, and a second edge 5013. The connecting strip 5011 is connected to the thermal insulation strip 101, and the first edge 5012 and the second edge 5013 are installed alternately on the connecting strip 5011. During installation, the first edge 5012 is installed closer to the outdoor profile 102, and the second edge 5013 is installed closer to the indoor profile 103, with the length of the first edge 5012 being greater than the length of the second edge 5013. After the insulating glass 401 is installed, both the first edge 5012 and the second edge 5013 abut against the insulating glass 401, and both the first edge 5012 and the second edge 5013 are inclined towards the outdoor profile 102.

[0023] Reference Figure 1 After the insulated glass 401 is installed, a watertight cavity 601 is formed between the outdoor profile 102, the first limiting edge 201, the insulated glass 401, and the first baffle 5012. When rainwater enters the outdoor profile 102 through the insulated glass 401, it is blocked by the flexible sealing strip 501 (first baffle 5012) and flows into the watertight cavity 601. An airtight cavity 701 is formed between the indoor profile 103, the second limiting edge 301, the insulated glass 401, and the second baffle 5013. This airtight cavity 701 prevents the exchange of air between the indoor and outdoor spaces, thereby improving the comfort of living.

[0024] In order to facilitate the collection of rainwater in the watertight cavity 601, a water collection tank 801 is also provided in the watertight cavity 601 in this embodiment. The water collection tank 801 can discharge the rainwater in the watertight cavity 601 to the outside.

[0025] In order to achieve a quick connection between the flexible sealing strip 501 and the heat insulation strip 101, in this embodiment, a groove 901 is provided on the side of the heat insulation strip 101 near the insulating glass 401, and a locking block 902 adapted to the groove 901 is provided on the side of the connecting strip 5011 near the heat insulation strip 101, and the locking block 902 is engaged with the groove 901.
