Building door and window self-telescopic locking seal hardware structure

Abstract

The invention relates to the technical field of building door and window hardware systems, in particular to a building door and window self-telescopic locking seal hardware structure which comprises transmission assemblies, corner assemblies, connection transmission lock point assemblies, a middle lock angle driver, a lever handle and a lock base. The corner assemblies are fixedly arranged on thefour corners of the outer side wall of a window sash, the connection transmission lock point assemblies are fixedly arranged on an upper frame and a lower frame of the outer side wall of the window sash, and the two ends of the connection transmission lock point assemblies are fixedly connected with the corner assemblies on the two corners of the upper and lower ends of the window sash. The transmission assemblies are fixedly arranged on a side frame on one side of the window sash in an up-down symmetrical mode. The middle lock angle driver is fixed to a side frame, opposite to the side framewhere the transmission assemblies are arranged, of the window sash. According to the building door and window self-telescopic locking seal hardware structure, the structure is reliable, universality is high, the building whole window air tightness can be remarkably improved, building energy saving standards are improved, and the requirements of passive ultralow-energy-consumption buildings on window system air tightness can be met.

Description

technical field [0001] The invention relates to the technical field of building door and window hardware systems, in particular to a self-expanding locking and sealing hardware structure for building doors and windows. Background technique [0002] At present, China's energy-saving standards for residential buildings and public buildings have entered the third energy-saving stage of 65% energy-saving. Some cities and provinces have begun to implement the energy-saving 75% standard. With the continuous improvement of energy-saving standards, especially the promotion and application of passive low-energy buildings, Relevant standards such as energy saving put forward higher requirements for the airtightness and watertightness of the building's external window system. For the casement window system widely used in severe cold and cold regions, the hinge connection side of the window sash and the window frame cannot be stretched inward due to the hinge.

[0002] At present, China's energy-saving standards for residential buildings and public buildings have entered the third energy-saving stage of 65% energy-saving. Some cities and provinces have begun to implement the energy-saving 75% standard. With the continuous improvement of energy-saving standards, especially the promotion and application of passive low-energy buildings, Relevant standards such as energy saving put forward higher requirements for the airtightness and watertightness of the building's external window system. For the casement window system widely used in severe cold and cold regions, the hinge connection side of the window sash and the window frame cannot be stretched inward due to the hinge. Compress the sealing material on this side profile, resulting in the airtightness of the unit seam length on this side is much lower than that of other surrounding unit seams. Although starting from the hardware subsystem and sealing subsystem can improve the airtightness of the whole window, but This part is still one of the worst parts of the whole window airtightness. In addition, the door and window system has a long service period. Due to the aging, deformation and falling off of the sealing material, it will still make it difficult for the window system to meet the 75% energy-saving standard and the ultra-low energy consumption of the passive house building facing the window.
