In more detail, a multi-turn spiral protruding cam is formed on the rotary shaft installed in the fuselage to which the fixing piece is attached, and then inserted into a right-turn spiral guide groove formed on the upper and lower reciprocating operation pipes. When the reciprocating automatic tube is operated up and down according to the rotation of the rotary shaft, the piston installed at the bottom of the reciprocating operation tube moves up and down in the cylinder. While the oil is moved up and down the piston through the flow path at this time, the buffer is generated by the hydraulic pressure acting during the movement of the oil to slowly close the door installed by the door rotation shaft of the present invention.

When the reciprocating actuating pipe 32 is lowered by the protruding cam 31 and the piston 36 is lowered, hydraulic pressure is generated in the cylinder 12, and the oil outlet 22 which can be adjusted by the needle valve 23 is oil. ) And the flow path 21 associated with the upper end of the cylinder 12 to the upper portion of the piston 36. At this time, the oil is flowed in the process of cushioning by the hydraulic pressure is made so that the door 62 is closed slowly. When the piston 36 keeps descending and blocks the '[' type flow path 20 and the outlet 22 at the same time, the piston 36 stops descending and stops the door 62 from closing at the same time. do. In this process, the oil in the cylinder 12 is flowed between the cylinder 12 and the piston 36 by the elastic force of the coil spring 49a. When the flow path 20 of the '[' type is opened, the hydraulic pressure is reduced. Nearly apart, the door is accelerated by the elastic force of the coil spring 49a and closes at a high speed. And the center of the rotary tube 41 is connected to the rotary shaft 30 and the connection ring 40 installed on the upper portion of the body 11, the ruler tapered on the upper surface of the support tube 42 for supporting the rotary shaft 30 The groove 43 is formed so that the tapered ruler protrusions 45 formed on the lower portion of the presser ring 44 are inserted into the recessed portion, and the presser pin 46 is driven to the connecting ring 40 so as to be operated up and down. It is to be pressed on the holding ring 40, the washer 47 installed on the upper end of the holding pin 46 is pressed by a coil spring 49 wound around the holding pipe 48 to maintain the rotated state at a predetermined angle. . In order to return to the original position in case of fire, the low melting point metal ring 50 is inserted into the upper portion of the coil spring 49 and fixed to the rotating shaft 30 by the bolt 51, so that the temperature is higher than a predetermined temperature during the fire. When raised, the low melting point metal ring 50 melts and falls, so that the elastic force of the coil spring 49 is extremely weakened and tapered by the elastic force of the coil spring 49a installed on the outer circumference of the fuselage 11 and the rotary tube 41. Since the tapered ruler protrusions 45 in the ruler groove 43 are terminated and returned to their original positions, the square protrusion rods formed on the upper portion of the cap 60 connected to the upper portion of the rotary tube 41 are fixed. The door 62 installed in the 61 is closed, so there is an advantage of minimizing the damage caused by the fire.
