Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a pressure line structure. Background Technology

[0002] In the door and window industry, the glazing bead is also called a "fastening strip" or "glazing strip." It is a thin, long profile installed inside the window or sash frame to firmly hold and fix the glass in place, while simultaneously concealing the gap between the glass edge and the profile, thus balancing safety, sealing, and aesthetics. Conventional aluminum alloy door and window glazing bead installations, such as the glazing bead assembly for aluminum-wood composite windows disclosed in patent publication number CN206681610U, involve snapping it onto the interior surface, requiring a certain amount of operating space. However, in actual on-site installation, various special scenarios may arise, such as obstacles on the interior surface preventing operation. Therefore, some installations use reverse installation of the window frame, placing the glazing bead externally. However, this installation method poses safety hazards. Utility Model Content

[0003] To address the shortcomings in the aforementioned background technology, this utility model proposes a composite pressure line structure for aluminum alloy windows, which solves the problems of high operating space requirements and difficulty in installation under special working conditions for conventional aluminum alloy door and window pressure line installation.

[0004] The technical solution of this utility model is implemented as follows: A composite pressure line structure for aluminum alloy windows is set between the frame and the glass, including a lower pressure line assembly set at the lower part of the frame and an upper pressure line set at the upper part of the frame; the lower pressure line assembly includes a pressure line base fixed on the frame, and a decorative pressure line is snapped onto the pressure line base; an inner adhesive strip is provided between the upper pressure line, the decorative pressure line and the glass. The pressure line base can both restrict the glass to prevent it from falling out and provide a snap-on base point for the decorative pressure line; it can also be quickly installed when it is blocked by obstacles such as walls; in this embodiment, the snap-on upper pressure line and the decorative line connected to the pressure line base cooperate to ensure the safety and sealing of the door and window, and make the installation convenient and quick.

[0005] Further preferably, the frame includes an inner aluminum frame, a heat insulation strip, and an outer aluminum frame, with the heat insulation strip located between the inner and outer aluminum frames and engaging with them to ensure the stability of the frame.

[0006] Further optimization involves the lower pressure line assembly and the upper pressure line being snapped onto the corresponding inner aluminum of the frame, with an outer adhesive strip between the outer aluminum of the frame and the glass, thus improving the overall sealing performance.

[0007] Further optimization involves an integrally formed left and right latch on the connecting surface of the aluminum frame, which together form a latching groove. The pressure line base and the upper pressure line are engaged in the corresponding latching groove, and the pressure line base is fixed to the aluminum frame with screws. This ensures the stability of the pressure line base, minimizes the error tolerance in the installation of the decorative pressure line, and achieves one-time molding for positioning, improving strength and facilitating installation.

[0008] Further optimization reveals that the wire clamping base includes a base profile, with a short arm clamping part and a long arm clamping part on the upper part of the base profile, and a hanging part on the right side of the base profile, with a clamping protrusion on the hanging part corresponding to the right clamping claw; this improves installation efficiency while ensuring the stability of the clamping.

[0009] Further preferred, the bottom of the seat profile has a protrusion, and the seat profile has a connecting hole, which corresponds to the threaded hole set in the snap-fit ​​groove; the screw passes through the connecting hole and can be threadedly connected to the threaded hole.

[0010] Further preferred, the decorative molding includes a molding profile body, with a vertical stop arm and a first claw at the lower part of the molding profile body, the vertical stop arm and the first claw forming a first groove, and a short arm engaging part engaging in the first groove; a horizontal stop arm is provided on the right side of the molding profile body, with a second claw and a third claw on the horizontal stop arm, the second claw forming a second groove with the molding profile body, and a long arm engaging part engaging in the second groove; and an inner glass adhesive strip engaging between the third claw and the glass.

[0011] Further optimization involves aligning the vertical stop arm with the inner aluminum side of the frame to ensure aesthetics; and positioning the short arm latch above the left claw to guarantee overall stability and strength.

[0012] Further optimization involves providing a left straight jaw and a right arc-shaped jaw on the connecting surface of the upper pressure line. The left straight jaw engages with the left jaw, and the right arc-shaped jaw engages with the right jaw.

[0013] Further optimization involves providing a fourth clamping claw on the right side of the upper pressure line, with the inner sealant strip positioned between the fourth clamping claw and the glass; this ensures the stability of the inner sealant strip while improving overall sealing performance.

[0014] The beneficial effects of this utility model are as follows: This utility model adopts a composite installation method in which the upper pressure line is directly snapped on, and the lower part uses a decorative pressure line and a pressure line base snapped on. This satisfies the installation requirements in limited space while ensuring overall strength and aesthetics. The pressure line base can be fixed to the frame with screws. The decorative pressure line is snapped onto the pressure line base. The snapping of the decorative pressure line and the pressure line base is opposite to the direct snapping of the upper pressure line to the frame, requiring no large installation space and suitable for the installation of pressure lines in narrow spaces. It solves the problem that normal pressure line installation requires a large operating space and is difficult to install under special working conditions.

[0015] When the frame is in normal condition, it is secured with a clamping wire. When it is blocked by obstacles such as walls, it can be secured using decorative clamping wire, clamping wire base, and screws. The clamping wire base can both restrict the glass from falling out and provide a locking point for the decorative clamping wire. This improves installation stability and enhances the overall wind pressure resistance, air tightness, and water tightness. It ensures the safety and sealing of doors and windows while making installation and maintenance faster and more convenient. It has the advantages of scientific structural design and strong practicality. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1, as Figure 1This invention discloses a composite pressure line structure for aluminum alloy windows. The pressure line structure is positioned between the frame 1 and the glass 7. Specifically, the composite pressure line structure includes a lower pressure line assembly located at the lower part of the frame 1 and an upper pressure line 6 located at the upper part of the frame 1. Typically, interior surface obstructions can hinder the installation of the pressure line at the lower part of the frame. The lower part of the frame 1 uses the lower pressure line assembly. The lower pressure line assembly includes a pressure line base 3 fixed to the frame 1. The pressure line base can be connected to the frame using screws. A decorative pressure line 4 is snapped onto the pressure line base 3. The snapping of the decorative pressure line with the pressure line base 3 is similar to the snapping of the upper pressure line directly onto the frame, requiring minimal installation space and suitable for installation in confined spaces. The upper pressure line 6 is directly snapped onto the upper part of the frame. In other words, this invention uses a composite installation method where the upper part of the frame is directly snapped onto the upper pressure line, and the lower part uses a composite installation method where the decorative pressure line and the pressure line base are snapped together. This satisfies the requirements for installation in limited spaces while ensuring overall strength and aesthetics. It solves the problems of high operating space requirements and difficulty in installation under special working conditions associated with normal pressure line installation. In this embodiment, an inner sealant strip 5 is provided between the upper pressure line 6, the decorative pressure line 4 and the glass 7 to improve the overall sealing performance.

[0020] In this embodiment, the frame 1 includes an inner aluminum 101, a thermal break strip 102, and an outer aluminum 103. The thermal break strip 102 is located between the inner aluminum 101 and the outer aluminum 103 and is snap-fitted into them. Making the frame a three-cavity composite structure of "inner aluminum + thermal break strip + outer aluminum" essentially separates and integrates the three functions of "load-bearing frame, thermal break, and outdoor protection" into a single profile, making the indoor side robust, the outdoor side weather-resistant, and the middle completely thermally insulated, resulting in a lightweight, economical, and energy-efficient window.

[0021] In this embodiment, specifically, the lower pressure line assembly and the upper pressure line 6 are respectively snapped onto the corresponding inner aluminum 101 of the frame. The pressure lines press from the indoor side to the edge of the glass, serving the following purposes: 1. Fixing the glass: preventing the glass from shifting under wind pressure or impact; 2. Sealing and dustproofing: working with the adhesive strip to prevent air, rainwater, and dust from entering the room; 3. Decorative finishing: covering the burrs and adhesive seams at the edge of the glass, resulting in a cleaner appearance. An outer adhesive strip 8 is provided between the outer aluminum 103 of the frame and the glass 7 to ensure sealing; glass pads 9 are provided on the thermal insulation strip 102 and the outer aluminum 103 of the frame to support the glass and ensure its stability.

[0022] Example 2, as Figure 3This embodiment illustrates a composite pressure line structure for aluminum alloy windows. Based on Embodiment 1, this embodiment further optimizes the structure. Specifically, the connecting surface of the aluminum 101 within the frame is provided with an integrally formed left claw 101-2 and a right claw 101-3, forming a snap-fit ​​groove 101-1. The pressure line base 3 and the upper pressure line 6 are snapped into the corresponding snap-fit ​​grooves 101-1, and the pressure line base 3 is fixed to the aluminum 101 within the frame by screws 2. After the pressure line base 3 is snapped into the aluminum 101 within the frame, it is locked by screws 2. The pressure line base 3 both restricts the glass 7 from falling out and provides a snap-fit ​​base point for the decorative pressure line 4. Normally, the frame 1 is secured using the pressure line 6. When obstructed by a wall 10, the decorative pressure line 4, the pressure line base 3, and the screws 2 can be used for securing. Figure 2 .

[0023] like Figure 4 In this embodiment, the wire pressing base 3 includes a base profile 301. The upper part of the base profile 301 is provided with a short arm snap-fit ​​part 302 and a long arm snap-fit ​​part 303. The short arm snap-fit ​​part 302 and the long arm snap-fit ​​part 303 are integrally formed with the base profile 301. The right side of the base profile 301 is provided with a hanging part 304. The hanging part is integrally formed with the base profile, and the hanging part 304 is provided with a snap-fit ​​protrusion 305 corresponding to the right claw 101-3. This ensures the firmness of the wire pressing base and the aluminum buckle in the frame, and at the same time facilitates quick snap-fit ​​installation.

[0024] As a preferred embodiment, the bottom of the base profile 301 is provided with a protrusion 306, which serves to prevent slipping, provide backup water drainage, and improve the rigidity of the profile. The base profile 301 is provided with a connecting hole, which corresponds to the threaded hole provided in the snap-fit ​​groove 101-1; the screw 2 passes through the connecting hole and can be threaded into the threaded hole; it is used to fix the pressure line base; the pressure line base is directly locked to the aluminum inside the frame with screws, anchoring the force path to the most rigid metal main frame of the entire window at one time, thereby improving wind pressure resistance, air tightness, and water tightness.

[0025] In this embodiment, the decorative molding 4 includes a molding profile body 401. The lower part of the molding profile body 401 has a vertical stop arm 402 and a first claw 403. The vertical stop arm 402 and the first claw 403 are integrally formed with the molding profile body, forming a first groove. A short arm engaging part 302 engages within the first groove. A horizontal stop arm 404 is located on the right side of the molding profile body 401. A second claw 405 and a third claw 406 are located on the horizontal stop arm 404. The second claw 405 forms a second groove with the molding profile body 401, and a long arm engaging part 303 engages within the second groove. Thus, the molding base and the decorative molding form two engagements, ensuring the stability of the connection after pressing. The inner glass adhesive strip 5 is engaged between the third claw 406 and the glass 7, ensuring both the stability of the inner glass adhesive strip and the sealing performance. The vertical arm 402 is flush with the side of the aluminum 101 inside the frame, ensuring an aesthetically pleasing installation; the short arm latch 302 is located above the left latch 101-2, providing more stable load-bearing capacity.

[0026] In this embodiment, the connecting surface of the upper pressure line 6 is provided with a left straight claw 601 and a right arc-shaped claw 602. The left straight claw 601 engages with the left claw 101-2, and the right arc-shaped claw 602 engages with the right claw 101-3. The straight claw and the arc-shaped claw engage with the aluminum inside the frame to ensure the stability of the engagement. A fourth claw 603 is provided on the right side of the upper pressure line 6, and the inner glass adhesive strip 5 is located between the fourth claw 603 and the glass 7; this ensures both the stability of the inner glass adhesive strip and the sealing performance.

[0027] like Figure 5 In this utility model, the frame 1 is normally secured with a pressure line 6. When it is blocked by obstacles such as walls, it can be secured with a decorative pressure line 4, a pressure line base 3, and screws 2. The pressure line base is directly locked to the aluminum inside the frame with screws, anchoring the force path to the most rigid metal main frame of the entire window at once, which improves wind pressure resistance, air tightness, and water tightness. Importantly, the pressure line and the pressure line base 3 are secured together, with the pressure line directly securing to the frame, requiring no large installation space, making it suitable for installing pressure lines in narrow spaces.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
