Description

Technical Field

[0001] This utility model relates to the field of roller shutter door post technology, specifically to a roller shutter door post cover plate installation structure. Background Technology

[0002] In Tianyou Technology, the doorpost cover plates for roller shutter doors are typically snapped onto the opening of the doorpost, creating an overlap between the doorpost and the cover plate, which is then fixed with bolts. After the bolts are fixed, the cover plate protrudes, creating gaps in the overlapping area and causing it to be out of sync, affecting aesthetics. Some designs use a snap-on method, where the cover plate extends to the sides of the doorpost and fits against the side wall, then is fixed from the side with bolts. While this method avoids gaps between the doorpost and the cover plate, it makes it difficult to install the cover plate when the doorpost is typically installed against a wall. The extended portion of the cover plate needs to be cut off before installation, which also affects aesthetics and is inconvenient for installation and disassembly. Therefore, a nail-free or bolt-free roller shutter doorpost cover plate installation structure is proposed. Utility Model Content
