An underwater travel switch structure converting linear motion into rotary motion

Abstract

The utility model relates to underwater stroke switch technical field discloses an underwater stroke switch structure of linear motion is converted to rotary motion, including waterproof casing, waterproof casing inside is provided with motion conversion subassembly, and motion conversion subassembly includes rotary trigger head and worm, and rotary trigger head rotationally connects at waterproof casing top, and worm fixedly connects at rotary trigger head bottom, and worm penetrates and connects at waterproof casing top wall, and waterproof casing inside is provided with shaft body, and shaft body rotationally connects with worm wheel, and worm wheel engages and connects at worm outside lateral tooth surface, and worm wheel side end face center fixedly connects with eccentric wheel. The utility model discloses through worm wheel and worm and eccentric link drive, and the linear pressing of inside switch is converted to the outside rotation, shortens dynamic sealing friction stroke, reduces the abrasion and the risk of water seepage. The buffer effect of transmission subassembly weakens the axial impact, and reduces the bounce frequency when the contact is pressed. Cooperation sealing inner shell and peripheral water blocking ring, constructs end face water seepage barrier.
