Description

Technical Field

[0001] The utility model relates to the technical field of window frame fixing, in particular to a centrally mounted shutter clamp. Background Art

[0002] Civil buildings have an increasing demand for sunshade. Built-in blinds and hollow glass have always been the star product in the sunshade industry. The combination of the frame and glass of built-in blinds and hollow glass (called lamination in the industry) is almost the same as the production process of hollow glass. A layer of pudding-based glue needs to be applied on the central blind frame. The applied pudding-based glue serves as a seal for the central blind. However, when the built-in blind is large in size, the deadweight of the built-in blind itself is also large, and the rectangular frame is easy to deform. At this time, the thickness of the pudding-based glue applied is uneven, and the colloid width is too wide. The frame is unevenly narrow, bent, discontinuous, and has broken marks. Gaps are prone to appearing at the joints of the louver frames. The louver frame joints are deformed and squeezed, causing the cover to fall off or deform. The accessories in the frame are prone to fall off or dislocation during the shaking and deformation process. Gaps appear at the corners of the spacer strips, desiccant leaks out, the corners of the spacer strips are loose, the frame falls off and falls apart, and the corners are prone to deformation and breakage during the shaking process. This makes the built-in louver insulating glass easy to fog and expose, affecting the product's aesthetics, affecting the product quality, and easily causing the product to fail to use normally.
