Description

TECHNICAL FIELD

[0001] The utility model relates to the field of roller shutter, especially to an elastic buckle seat, a roller shutter track and a windproof roller shutter. BACKGROUND

[0002] The windproof roller shutter is an additional product applied to outdoor leisure pavilions, awnings, sunshades and other outdoor products, used for blocking sunlight or wind on one side. Elastic pieces or elastic blocks are usually arranged in the two side tracks of the windproof roller shutter to tighten the curtain fabric on both sides and prevent the curtain fabric from being deflected when subjected to wind resistance.

[0003] The wind resistance in different regions and at different times is different. To meet the demand, different numbers of elastic pieces are arranged in the track to ensure that the curtain fabric does not deflect. However, too many elastic pieces arranged in the track will affect the smoothness of the roller shutter, and too few elastic pieces may cause insufficient pulling force, which still causes the curtain fabric to deflect.

[0004] On the existing windproof roller shutter, to prevent the elastic pieces or elastic blocks from falling out of the two side tracks, they are usually fixed in the track by adhesion or screw fastening, such as the screw fixing shown in CN217760807U. Figure 2 The screw fastening method requires pre-drilling screw holes on the chain track. Excessive pre-drilled screw holes will weaken the structure of the chain track. The adhesion method requires waiting for a certain period of time for the glue to solidify, which wastes time. Both methods are inconvenient. SUMMARY
