Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and particularly relates to a split middle mullion connecting piece structure and a door and window. Background Technique

[0002] In the manufacturing and installation process of aluminum alloy doors and windows, the middle mullion connecting piece, as a key accessory, its performance directly affects the overall stability, sealing performance and service life of the doors and windows. It is mainly used for connecting two aluminum alloy profiles at the corner. Usually made of aluminum alloy, it has many advantages such as good stability, strong weather resistance, not easy to deform, and long service life, and has a wide application in the installation of household doors and windows. The traditional middle mullion connecting piece mostly adopts an integral structure, which meets the basic connection requirements to a certain extent.

[0003] The Chinese invention patent with the publication number of CN104847232A discloses a middle mullion connecting piece for aluminum alloy casement doors and windows. It specifically includes a connecting piece body. The two side surfaces of the connecting piece body are serrated. A through hole is opened in the middle of the connecting piece body. One end of it is recessed inward on both sides to form grooves that match the surface of the column. An opening communicating with the through hole is opened at the other end. The cross beam is sleeved from the opening end of the connecting piece body. The column and the cross beam form a 90° T-shaped connection. The width of the connecting piece body at the end with the opening is greater than the width of the end with the grooves.

[0004] However, the above-mentioned middle mullion connecting piece belongs to the integral structure, and often can only achieve single fixation. When facing a complex and changeable installation environment, it is easy to cause the gaps between the profile cavities to be unable to be effectively filled and sealed, which not only affects the airtightness and watertightness of the doors and windows, but may also cause the connection parts to loosen or be misaligned due to factors such as thermal expansion and contraction and wind force during long-term use, thereby affecting the overall stability and safety of the doors and windows.
