<p>A helmet capable of enhancing mask sealing performance includes a housing and a transparent lune-shaped mask (1) provided in front of the housing. The mask (1) is hinged with two open ends of a U-shaped mouth component. An ear-shaped clamping plate (2) is fixedly connected on the mouth component. The clamping plate (2) includes an ear-shaped board (3) and an approximately rectangular cover plate (4). The cover plate (4) is provided in a mounting hole (22) of the board (3) and can slide in the mounting hole (22). A spring (10) is provided between the cover plate (4) and the mounting hole (22). An arc-shaped guiding edge (5) is provided on the board (3), and the mask (1) is hinged on the cover plate (4), thereon a guiding block (6) which is matched with the arc-shaped guiding edge (5) being provided. When the mask (1) is buckled, under the function of the restoring force of the spring (10), the mask (1) is buckled tightly on the sealing strip on the edge of the mask (1) such that the mask (1) is prevented from being uncovered by the air flow when the motorcycle is driven at high speed.</p> |
