Claims

[Claims for Utility Model Registration] A pair of hinge cylinders provided on a coaxial line and each having a hinge blade, and a hollow shaft inserted into one of the pair of hinge cylinders. and an opening in the other hinge cylinder to allow the protrusion of the shaft protruding outside the one hinge cylinder to rotate into the other hinge cylinder, which is a bottomed cylinder. an oil chamber formed in the other hinge cylinder in which oil is sealed; a piston engaged in serration engagement with the tip of the protrusion of the shaft body; a female threaded portion formed on the inner periphery of the other hinge cylinder that is screwed into the outer peripheral male threaded portion; a fitting hole formed inside the piston into which the tip of the protrusion of the shaft body fits; the piston and the shaft. a sliding hole formed between the protrusion of the body and serving as an oil passage; a speed regulating passage and a valve passage formed at the tip of the piston so as to communicate from the fitting hole to the outside of the piston; a check valve disposed on the outside of the valve passage; a regulating rod rotatably inserted into the hollow portion of the shaft and having a tapered side surface inserted into the regulating passage; , a spring made of one or more shape memory alloys with different temperature characteristics, which is inserted into the hollow part of the shaft and is arranged to push the regulating rod downward; and one end of the shaft. a speed regulating screw screwed into the side and connected to one end of the spring, and the opening/closing speed is adjusted by rotating the speed regulating screw, and the opening/closing speed is adjusted according to the temperature change of the oil. A damper hinge characterized in that a spring made of the shape memory alloy expands and contracts in accordance with the demand.
