CLAMPING STRUCTURE FOR FASTENING HOSE

摘要

PURPOSE: A clamping structure is provided to durably maintain a connecting portion between hoses in an airtight or watertight manner by allowing a fastened state of a hose to be reliably maintained regardless of change in outer diameter of the hose due to aging thereof. CONSTITUTION: A clamping structure comprises a clamp spring(3), a fastening bolt assembly(5) and a clamp plate(1). The clamp spring(3) is circular in shape in order to surround a hose. The clamp spring(3) is configured to form a plurality of asperities along its circumference. The fastening bolt assembly(5) is connected to a flat section provided on the clamp spring(3). The fastening bolt assembly(5) is adapted to be tightened as the clamp spring(3) slides. The clamp plate(1) abuts against an inner peripheral surface of the clamp spring(3) to form the circumference of a circle. Opposite ends of the clamp plate(1) are slidingly connected to the flat section of the clamp spring(3).
