Description

Technical Field

[0001] This utility model belongs to the field of door and window structure technology, specifically relating to a high watertight pressure line structure for improving the sealing performance between door and window glass and frame profile. Background Technology

[0002] Doors and windows consist of components such as profiles, glass, hardware, and sealing materials, and the combination of these components directly affects the overall performance of the doors and windows. During the manufacturing and processing of doors and windows, performance requirements must be met while also considering ease of installation.

[0003] In existing window and door systems, the glass and frame are typically sealed with rubber strips. As wind pressure changes, the seal gap is dynamic, adjusted by the elasticity of the rubber strip. This structure often experiences seal failure during heavy rain and strong winds: a small amount of rainwater enters below the glass and drains through the drainage holes. When positive wind pressure acts on the window or door surface, the amount of water entering increases while drainage capacity decreases, leading to water accumulation below the glass and seepage into the room. Furthermore, existing glazing bead systems are often rigidly connected to the frame profiles, leaving insufficient space for sealing, making the glazing bead a potential source of water leakage. Utility Model Content

[0004] This invention addresses the aforementioned problems by providing a highly watertight pressure wire structure with reliable sealing.

[0005] This utility model adopts the following technical solution: It includes a window frame profile, an outer edge on the exterior side of the window frame profile, and a pressure line assembly on the interior side of the window frame profile. A glass panel is disposed between the pressure line assembly, the window frame profile, and the outer edge. The pressure line assembly comprises a pressure line base and an outer pressure line. The pressure line base has a U-shaped cross-section, and its lower part engages with a groove on the window frame profile. The outer pressure line has an L-shaped cross-section, and a groove is provided on one side of its vertical portion. A molded clip is disposed within the groove, and the molded clip engages with the upper end of the pressure line base. The horizontal portion of the outer pressure line is positioned above the vertical portion and corresponds to the glass panel.

[0006] In a preferred embodiment of this utility model, the pressure line base and the window frame profile are fixed together by screws.

[0007] As another preferred embodiment of this utility model, a sealant is provided between the pressure line substrate and the window frame profile on one side surface of the glass plate.

[0008] As a third preferred embodiment of this utility model, an inner adhesive strip is provided between the horizontal portion of the outer buckle and the glass panel; an outer adhesive strip is provided between the outer edge of the window frame profile and the glass panel.

[0009] Advantages of the present utility model: 1. By setting the wire pressing component as a structure composed of a wire pressing base body and an external snap-on wire pressing, where the cross-section of the wire pressing base body is "匸"-shaped and is snap-fitted with the notch on the window frame profile, the wire pressing base body can be firmly positioned, enhancing the structural stability and avoiding the problem of water leakage caused by looseness at the connection between the wire pressing and the window frame profile.

[0010] 2. The external snap-on wire pressing has an L-shaped cross-section. The vertical part is snap-fitted with the wire pressing base body through an injection molding clip, forming a reliable snap connection. The horizontal part is pressed on the glass plate member, thus forming a double support in the structure and making the wire pressing installation more firm.

[0011] 3. The wire pressing base body and the window frame profile are fixed by screws. The wire pressing base body not only relies on snap positioning but also increases the mechanical fixing force, ensuring that the wire pressing is not easily loosened during long-term use and improving the durability.

[0012] 4. Sealant is filled at the position between the wire pressing base body and the glass plate member, effectively filling the tiny gaps and further enhancing the sealing performance at the wire pressing. Even under strong impacts of wind pressure and rain, the sealing effect can still be maintained.

[0013] 5. A glass inner rubber strip is provided between the horizontal part of the external snap-on wire pressing and the glass plate member, and a glass outer rubber strip is provided between the outer edge of the window frame profile and the glass plate member, forming an internal and external double-sealing structure. This double-sealing can not only prevent rainwater from entering from the outside but also block the air flow between indoors and outdoors, thus significantly improving the overall waterproofness and airtightness of the doors and windows.

Detailed Embodiment

[0017] As shown in the figure, a high watertight wire pressing structure of the present utility model includes a window frame profile 1. An outer edge 2 is provided on the outdoor side of the window frame profile 1. A wire pressing component 3 is installed inside the window frame profile 1. A glass plate member 4 is clamped and fixed between the wire pressing component 3, the window frame profile 1, and the outer edge 2.

[0018] The pressure line assembly 3 consists of a pressure line base 31 and an outer pressure line 32. The pressure line base 31 has a "U"-shaped cross-section, and its lower part engages with the groove 11 on the window frame profile 1, ensuring that the pressure line base 31 can be stably installed on the window frame profile 1. Based on this engagement, the pressure line base 31 is further fixedly connected to the window frame profile 1 by screws 12, thereby improving the overall connection strength and preventing loosening due to temperature changes or external forces during long-term use.

[0019] The outer clamping wire 32 has an L-shaped cross-section, with a slot 321 on one side of the vertical portion. A molded clip 322 is embedded within the slot 321. The molded clip 322 engages with the upper end of the clamping wire base 31, allowing the outer clamping wire 32 to be securely fastened to the base 31. This structure provides a vertical clamping effect for the outer clamping wire 32, while its horizontal portion 322 rests above the glass panel 4, effectively preventing rainwater from seeping in through the gap between the clamping wire and the glass.

[0020] To further improve sealing performance, sealant 5 is filled between the pressure line substrate 31 and the window frame profile 1 on the side near the glass panel 4. This sealant effectively fills small gaps and enhances the watertightness of the pressure line. Even under conditions of strong winds and heavy rain, the sealant 5 forms a barrier to prevent rainwater from seeping into the room.

[0021] Meanwhile, an inner sealing strip 6 is installed between the horizontal portion of the outer retaining line 32 and the glass panel 4 to form an inner seal; an outer sealing strip 7 is installed between the outer edge 2 of the window frame profile 1 and the glass panel 4 to form an outer seal. The two sealing strips work together to prevent external rainwater from entering below the glass and to block air convection, further improving the overall waterproofness and airtightness.

[0022] As can be seen from the above embodiments, the high watertightness pressure line structure of this utility model utilizes the combination structure of the split pressure line base and the external pressure line, the snap-fit ​​effect of the injection-molded clips, the fixing of screws, and the synergistic effect of sealant and double-layer adhesive strips. This not only improves the stability and ease of construction of the structure, but also significantly enhances the sealing performance of the pressure line area and the glass edge, ensuring that the doors and windows can maintain good watertightness and service life even in strong winds and rain.

[0023] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
