Description

Technical Field

[0001] This utility model relates to the field of door and window installation technology, specifically to a mullion connection structure. Background Technology

[0002] Aluminum alloy windows are windows with frames and sashes made of aluminum alloy building profiles. They are divided into ordinary aluminum alloy doors and windows and thermally broken aluminum alloy doors and windows. Aluminum alloy windows are characterized by their aesthetics, airtightness, and high strength, and are widely used in the construction industry. In home decoration, aluminum alloy doors and windows are commonly used to enclose balconies.

[0003] When using existing mullion connectors, the mullion connector is usually fixed to one side of the door / window profile first, and then the other door / window profile in the vertical direction is fitted onto the mullion corner bracket for corner assembly. The mullion corner bracket passes through the frame and is tightened by set screws. Although this method can fix the mullion, when the mullion needs to be moved, it is impossible to quickly adjust the mullion because the set screws have already fixed the mullion corner bracket. The mullion must be removed, the mullion corner bracket screws loosened, the mullion corner bracket adjusted, and then the process repeated, which is complicated. Utility Model Content

[0004] To address the technical deficiencies in the background technology, this utility model proposes a mid-bracket connection structure, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0005] A mullion connection structure includes a frame profile, a central column profile, and a mullion angle bracket. The central column profile is vertically fixed to the inner side of the frame profile, and the mullion angle bracket is provided between the end of the central column profile and the frame profile.

[0014] The beneficial effects of this utility model are as follows:

[0015] The bottom end of the center mullion slides along the sliding groove on the frame profile. The center post profile is sleeved on the center mullion. When fixed, the hex socket screw is screwed in to tighten the center post profile. At the same time, the ejector pin inserts into the frame profile to fix the center mullion. When it is necessary to adjust the position of the center post profile, simply loosen the hex socket screw. At the same time, the ejector pin is automatically removed from the frame by the spring, and the connection structure between the frame profile and the center mullion is released simultaneously. This achieves a way to quickly adjust the connection position between the center post profile and the frame profile without disassembling the center mullion and the center mullion.
