Technical Field
[0001] This utility model relates to the field of doors and windows, and in particular to a PVC exterior window structure that can be fitted with a security mesh window. Background Technology
[0002] PVC windows, following wood, iron, and aluminum alloy windows, were actively promoted by the government in the mid-1990s. Due to their lower price and good performance-to-price ratio, they are still widely used today.
[0003] With the high-quality development of society, many traditional materials are gradually being replaced. Take window screens, which are closely related to our daily lives, as an example. Traditional window screens are mainly made of nylon. In today's society, nylon window screens have been gradually phased out. First of all, they cannot be exposed to the sun for a long time. Once exposed to sunlight for a long time, their service life will be greatly shortened.
[0004] Diamond mesh security screens outperform traditional nylon screens in various aspects. Their application in PVC windows aims to comprehensively improve window quality and enhance security. However, installing diamond mesh security screens on existing PVC windows is relatively cumbersome due to their greater weight compared to nylon screens. It requires multiple people to align the screen with the door / window and then secure it with bolts. Therefore, a new PVC window structure capable of housing diamond mesh security screens is proposed. Utility Model Content
