Technical Field
[0001] The utility model relates to the technical field of ventilation window frames, in particular to a double L-shaped ventilation window corner connection frame. Background Art
[0002] Ventilation windows are a common decorative accessory. Modern decorating concepts place higher demands on their functionality and materials. Depending on the installation location, height, width, and climate conditions, ventilators require stronger materials and more rational structures to achieve a perfect combination of durability, operability, and aesthetics.
[0003] The products currently on the market are relatively simple. Whether it is a PVC ventilation window or a natural wood ventilation window, each has its own advantages and disadvantages.
[0004] In some ventilation windows, there are often situations where the windows need to be made into corners. The normal practice for windows is to use special corner profiles to connect two windows together to achieve the effect of window corners. However, since there are 3-4 types of profiles in the corner part, it greatly affects the ventilation area of the corner part, and affects the line of sight and indoor aesthetics.
