In more detail, the right rotating spiral protrusion cam is formed on the rotating shaft installed in the hinge body, and the right rotating spiral guide groove formed on the upper and lower reciprocating operation pipes is installed, and the left rotating spiral guide groove is formed on the outer circumference of the reciprocating operating tube. When the reciprocating actuation pipe descends or ascends in accordance with the rotation of the rotating shaft, the piston installed at the lower end of the reciprocating actuation tube reciprocates up and down in the cylinder and moves the oil into the piston. The upper and lower parts of the rotary shaft support tube, which are interleaved with the irregularities on the inner circumference of the upper body of the fuselage, are inserted into the rotary tube by the hydraulic pressure acting during the movement of the oil. The bottom surface of the presser ring, which is tapered by a tapered hanging groove on the upper surface and is first bitten by the rotating shaft and the uneven portion. Insert the tapered ruled protrusions formed and insert a plurality of push pins to operate the connection ring up and down, and install the washers on the upper surface of the push pins to hold the washers with a coil spring installed on the outer periphery of the pressure pipe, The bracket is installed on the upper part of the pressure pipe, and the adjustment bolt is screwed on the upper end of the rotating shaft to adjust the elastic force of the coil spring.The bracket is extended and inserted into the magnet installed on one side of the hinge.The magnet is installed in the control box. It is connected to the gas and heat sensor connected with the sensor, and if heat is generated over a certain temperature due to fire or gas is generated, it is detected by the detector and the magnet is operated to separate the bracket from the upper part of the pressure gauge tube. Accordingly, the present invention relates to an automatic return device of a hydraulically actuated shock absorbing hinge, which causes the door to close at a high speed due to the weakness of the coil spring being held down and the locking protrusion protruding from the locking groove by the elastic spring force of the restoring spring.
