Abstract: A swimming goggle includes an eyepiece frame, a head strap and two fastening assemblies for connecting the eyepiece frame and the head strap. Both sides of the eyepiece frame have a through-hole respectively. Both ends of the head strap have protrusions. The fastening assembly includes a fastening base and a shroud assembled with the fastening base. The fastening base has an operating arm formed with an engaging piece. The fastening base has three tongues, a locking hole corresponding to the through-hole, and a trough for allowing the head strap to pass through. The shroud has a hook disposed through the through-hole and engaged with the locking hole. The inner edge of the shroud is provided with three notches for allowing the three tongues to be inserted therein. By this structure, the present invention can be assembled firmly, and the head strap can be tightened or loosened easily.

Abstract: A swimming goggles buckle is latched to a head strap and swimming goggles. The head strap includes protruding strips. The swimming goggles buckle includes a fastener and a retaining component. The fastener includes connecting legs, a pivot portion and an elastic plate. The connecting legs latch the swimming goggles. The pivot portion is at the middle of the fastener. The elastic plate is installed on a side of the fastener. The retaining component includes a shaft, a latching portion and a press portion. The shaft is pivotally installed in the pivot portion. The latching portion is on a side of the shaft and corresponding to the protruding strips. The press portion is on another side of the shaft and corresponding to the elastic plate. The press portion is pressed to separate the latching portion or latch the protruding strips to adjust the length of the head strap by one hand.

Abstract: A buckle set, two of which pair off for being inset in frame of the swimming goggles on two sides so that a strap can be inserted in the buckle sets for fastening the swimming goggles on user's face. Structure of the present invention features a 2nd bump, which keeps the buckle in effective spacing even when the buckle is loaded with force and thus keeping the buckle well covered by the buckle hood.

Abstract: A swimming goggle structure includes two eye masks and a centrally located nose strap. Each eye mask has an outer edge forming a head strap buckle to which a head strap is connected and an inner edge forming a projecting joint section. The joint section forms a recessed slot and is jointed to an end of the nose strap by insert molding so that the end of the nose strap wraps and engages the joint section of each eye mask to form a tightly connected structure.

Abstract: A buckle set, which fits onto a strap for adjusting the strap to a desired length, generally fits onto the strap attached to goggles of almost any application, such as swimming goggles, scuba mask, or dust and wind goggles. Specifically, a buckle set allows a strap to easily and quickly be adjusted to a desired length from its two ends.
