Description

Technical Field

[0001] This utility model relates to the technical field of windproof curtains, specifically, a side rail structure for windproof curtains. Background Technology

[0002] The side rails of a windproof curtain are tracks installed on both sides of the curtain fabric to prevent the curtain from being blown up by the wind. To facilitate disassembly and maintenance, existing windproof curtain side rails are usually designed as separate units. For example, Chinese Patent CN213573814U discloses a wear-resistant and anti-lifting rail and a windproof roller blind incorporating this rail. The specification states that the side rail body includes a main rail plate and a secondary rail plate. One side of the main rail plate has a slot with a protrusion on its side wall. One side of the secondary rail plate has a locking strip that matches the slot, with a groove on the strip. The protrusion matches the groove. The secondary rail plate is installed on the main rail plate via the locking strip. The main rail plate and secondary rail plate can be installed simply by the engagement of the locking strip and the slot, without the need for screws.

[0003] However, in the existing side rail structure, since the clips are simply connected by two fasteners, a certain gap needs to be reserved between the groove and the protrusion for easy disassembly and maintenance. If no gap is left, the guide rail plate is easy to break during disassembly. As a result, the part of the guide rail plate in the slot is prone to swinging, which leads to instability of the entire windproof curtain side rail. Utility Model Content
