Swimming goggles have a left frame 2 and a right frame 3 respectively receiving lenses 5 therein, a connecting bridge 4 between the left frame 2 and the right frame 3, a head strap (8) with a plurality of abutting grooves, and buckles (7) for supporting the head strap. Each buckle (7) comprises an assembling frame 70 and a strap frame 71 pivotally assembled to each other. The assembling frame includes a pivoting shaft 701, an abutting arm 702 extending from the pivoting shaft 701, and a resilient arm 703 extending from the pivoting shaft and opposite to the abutting arm. Branches 704, 705 respectively extend from opposite sides of the resilient arm. A first controlling arm 706 and a second controlling arm 707 are formed on outward sides of the assembling frame (70) and adjacent to the branches for controlling the branches. The strap frame (71) defines a pivoting orifice 710 for pivoting to the pivoting shaft 701, and a guiding hole 712 for guiding the head strap. The head strap is operated by a couple of fingers, to aid ergonomics such that the strap may only be tightened without the controlling arms being squeezed together, but the strap may be both loosened and tightened when the controlling arms are squeezed together. |
