Description

Technical Field

[0001] This application relates to the field of PVC window and door technology, and more specifically, to a PVC window and door structure with good sealing performance. Background Technology

[0002] Door and window structures are crucial for indoor ventilation in buildings, ensuring indoor air quality and preventing health problems caused by poor air circulation. Traditional PVC door and window structures, with only a single sealing strip and double-glazed windows, achieve a certain level of sealing, but their sealing and sound insulation capabilities are still somewhat insufficient. When the doors and windows are completely closed, ventilation is inevitably lost, while opening them causes serious air leakage and noise interference. Therefore, we propose a PVC door and window structure with better sealing performance. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The purpose of this application is to provide a PVC window and door structure with good sealing performance, which solves the technical problems in the background art. This window and door structure achieves good sound insulation and structural strength by installing three layers of composite glass in the inner frame. A first sealing strip is installed on the outer frame and a second sealing strip is installed on the inner frame. When the inner frame is closed, both the first and second sealing strips are pressed together, forming two good sealing structures. A ventilation structure is set at the bottom of the outer frame, and a silicone sealing bladder is set inside the frame cavity. By adjusting the amount of air injected into the silicone sealing bladder, the sealing pressure of the silicone sealing bladder can be adjusted to fill the gaps inside the frame cavity, achieving good sealing performance. Compared with traditional windows and doors with a single sealing structure, the sealing performance is greatly improved, and the sealing capacity and ventilation can be adjusted according to needs.

[0005] 2. Technical Solution

[0006] This application provides a well-sealed PVC window and door structure, comprising: an outer window frame and an inner window frame rotatably connected by hinges. The inner window frame has a triple-layer composite glass panel fixed at its upper limit, and the joint between the inner window frame and the triple-layer composite glass panel is filled with glass sealant. The outer window frame has a frame-shaped inner cavity containing a silicone sealing bladder. A hardware frame and a first sealing strip frame are detachably snap-fitted onto the inner wall of the outer window frame. A first stop frame is fixed along the inner wall of the outer window frame. A connecting mechanism is provided between the inner window frame and the window frame. A second sealing strip frame is detachably snapped onto the inner window frame.

A convex mounting groove is provided on the bottom back surface of the inner window frame. A multi-hole cover plate is detachably and limitly installed at the convex mounting groove. The convex mounting groove, the frame cavity, and the ventilation grille groove are connected.

[0007] By adopting the above technical solution, the window and door structure consists of an outer frame and an inner frame hinged together. The inner frame houses triple-layered composite glass, with sealant injected along the edges to enhance sound insulation and structural strength. A hardware frame is installed on the outer frame to mount a connecting mechanism, which connects to the inner frame, limiting the maximum opening angle of the inner frame. A first sealing strip is installed on the outer frame, and a second sealing strip is installed on the inner frame. When the inner frame is closed, the second sealing strip abuts against the first sealing strip. By pressing the first retaining frame together, a double sealing structure is formed using the first and second sealing strip frames. Compared to the traditional single-seal strip structure, this door and window structure greatly improves the sealing performance. The convex mounting groove at the bottom of the outer frame, the inner cavity of the frame, and the ventilation grille groove are connected, allowing for a certain degree of ventilation after the inner frame is closed. Furthermore, a silicone sealing bladder is installed inside the inner cavity of the frame. By injecting different amounts of air into the silicone sealing bladder using an air pump, the sealing pressure of the silicone sealing bladder can be adjusted to fill the gaps inside the inner cavity of the frame, thereby achieving good sealing performance and realizing an adjustable sealing capacity.
