Abstract: An LED heat dissipation structure includes a heat sink, a cover plate, and an air blowing device. The heat sink has fins. Gaps between the fins form a plurality of continuous air flow channels, and air discharge ends of the air flow channels (16) extend to a peripheral surface of the heat sink. The cover plate covers the fins, closes openings of the airflow channels at tip portions of the fins, and partially bulges and forms an air inlet chamber communicating with the air flow channels. The air blowing device forcibly blows air into the air inlet chamber.

Abstract: Disclosed is a seal strip, comprising a tubular seal strip body with a first end (116) and a second end (117), wherein the first end (116) extends into the second end (117) and is securely connected to the second end (117) by a sewing thread (113). Further disclosed are a method and a device for sewing the seal strip, wherein the sewing device comprises a seal strip feeding machine (1), a device (2) for positioning the ends of the seal strip, a device for inwardly folding an edge of the seal strip, a device (3) for butt-joining the ends of the seal strip, a device (5) for threading a needle for the seal strip, and a device (4) for sewing the seal strip. The two ends of the seal strip are securely connected by the sewing thread, providing a high connection strength; and the method and device for sewing the seal strip can accomplish complete automation in sewing the seal strip, thus greatly improving efficiency during the production and processing of the seal strip.

Abstract: The present invention provides a kind of clip fastener for attaching gaskets or gasket-like devices to a mounting surface, including a mounting surface engagement head, a neck and a protrusive base perpendicular to the plane of the head and attached to the neck. The present invention also presents a kind of method and equipment for mounting a clip fastener with protrusive base to gasket. Clip fastener base in present invention can be embedded into gasket, or rotated into woven gasket, or embedded into gasket being weaving. The head extend outwards across gasket and clip fasteners in the holes on mounting surface to fasten gasket to mounting surface firmly and effectively.
