Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy profiles, in particular to an aluminum alloy door and window pressing line structure capable of resisting deformation due to external forces. Background Art

[0002] Door and window pressure strips, also known as door and window buckle strips or pressure strips, are the parts that come into direct contact with and hold down the glass. They come in a variety of shapes, with linear and arc-shaped designs being common. Pressure strips are typically connected to the door and window frames through clips, screws, or other mechanical connections. For example, in aluminum window frame pressure strip mounting systems, the arc pressure strip is secured to the inner window frame using pressure strip clamps.

[0003] With the development of the times, the glass used in aluminum alloy doors and windows has gradually increased. When the glass is affected by wind and other factors, the pressure on the glass will increase, and the strength requirements for the pressure lines of doors and windows will increase.

[0004] Some existing aluminum alloy door and window press-line structures rely on overlapping profiles and various structural combinations to prevent the press-line from popping out. However, when the press-line body is subjected to extreme stress and deformation, it cannot effectively provide support to resist external deformation, which can easily cause the profile to deform or even damage. To address this problem, we have proposed an aluminum alloy door and window press-line structure that can resist external force deformation. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-4 The utility model provides a technical solution for the wire pressing structure of aluminum alloy doors and windows that can resist deformation due to external forces: it includes a door and window frame 1 and a wire pressing body 2, and a side wall of the door and window frame 1 close to the glass is provided with a clamping groove 3 for connecting the wire pressing body 2, and the outer wall of the wire pressing body 2 is provided with a clamping part 4 adapted to the clamping groove 3, and the clamping part 4 is clamped and matched with the clamping groove 3 to realize the clamping and fixation of the wire pressing body 2. This is the existing technology and will not be described in detail here.

[0026] The clamping ends of the clamping part 4 (i.e., the force points of the wire pressing body 2 when the glass presses the wire pressing body 2) are connected to the inner wall of the wire pressing body 2 away from the clamping part 4 and form a supporting part 6. The formed supporting part 6 can strengthen the strength of the wire pressing body 2 to prevent it from deformation or damage.

[0027] A support plate 5 is slidingly provided on the door and window frame 1, which abuts against the clamping part 4. When the wire pressing body 2 is installed on the door and window frame 1, the clamping part 4 needs to be clamped in the clamping groove 3 first. During this process, the clamping part 4 will push the support plate 5 to slide on the door and window frame 1. A slot for inserting the support plate 5 is formed on the wire pressing body 2. The sliding support plate 5 will be inserted into the slot, and the support plate 5 will abut against one side of the wire pressing body 2 close to the glass. When the glass is subjected to external force and presses the wire pressing body 2, the support plate 5 will form a blocking effect on the side of the wire pressing body 2 close to the glass, further strengthening the strength of the wire pressing body 2 and preventing it from deformation or damage.

[0028] Specifically, the wire pressing body 2 is a triangular structure. The triangle is a stable structure that can better withstand the pressure and external force from the glass, and helps to evenly disperse the external force, reduce local stress concentration, and reduce the possibility of deformation.

[0029] The supporting portion 6 includes a reinforcing plate 61 fixedly connected to the clamping end of the clamping portion 4 (that is, the force point of the wire pressing body 2 when the glass presses the wire pressing body 2), and the ends of the reinforcing plate 61 are connected to the inner side wall of the wire pressing body 2 away from the clamping portion 4. These reinforcing plates 61 are interconnected and enclosed to finally form a regular triangular shape, so that the connection between the various components is more firm. A triangular-shaped supporting portion 6 is provided in the wire pressing body 2 with a triangular structure, and the mutual cooperation is more efficient, which provides a strong guarantee for the stability and reliability of the entire aluminum alloy door and window wire pressing structure, and further prevents deformation or damage of the wire pressing structure.

[0030] Specifically, a heat-insulating cavity 62 is formed between the reinforcing plates 61 to reduce heat conduction and increase the heat-insulating performance of the wire pressing structure.

[0031] Specifically, one of the clamping ends of the clamping portion 4 is fixed with a push plate 7, and the end of the support plate 5 extends into the clamping groove 3. A guide slope 52 is provided on the side of the support plate 5 facing the clamping portion 4. As the clamping portion 4 is clamped in the clamping groove 3, the clamping portion 4 will drive the push plate 7 to move toward the support plate 5, and make the end of the push plate 7 abut against the guide slope 52. As the push plate 7 moves, the push plate 7 makes the support plate 5 move toward the notch on the wire pressing body 2 under the guidance of the guide slope 52 and insert into the notch. An elastic member 51 is provided between the support plate 5 and the door and window frame 1. When the wire pressing body 2 is not installed, the elastic member 51 will retract the support plate 5 into the door and window frame 1 to prevent interference with the wire pressing body 2 and the clamping portion 4 when the wire pressing body 2 is installed.

[0032] Specifically, a thermal insulation groove 8 is formed between the support portion 6 and the inner wall of the wire pressing body 2. A first thermal insulation strip 9 is slidingly provided in the thermal insulation groove 8 and abuts against the inner wall of the wire pressing body 2, thereby further reducing heat conduction and increasing the thermal insulation performance of the wire pressing structure. The first thermal insulation strip 9 abuts against the inner wall of the wire pressing body 2, which can support the support portion 6.

[0033] Specifically, the clamping ends of the clamping parts 4 (i.e. the parts clamped and connected with the door and window frame 1) are provided with second insulation strips 10 that abut against the door and window frame 1, further reducing heat conduction and increasing the thermal insulation performance of the pressing structure.

[0034] Specifically, the outer wall of the wire pressing body 2 is fixed with an extended side plate 11 that abuts the glass to improve the blocking effect on the glass. The extended side plate 11 is provided with an arc-shaped surface on the side away from the glass. The arc-shaped surface can better disperse external force, reduce stress concentration, and improve the flatness and aesthetics of doors and windows.

[0035] Specifically, the outer wall of the wire pressing body 2 is fixedly connected to the door and window frame 1 with a reinforcing side plate 12. This ensures the stability and firmness of the wire pressing body 2 when installed on the door and window frame 1, improving the flatness and aesthetics of the door and window. A third insulation strip 13 is provided between the reinforcing side plate 12 and the door and window frame 1, which also improves the thermal insulation performance of the wire pressing structure.
