In FIG. 3, when the door 1 is closed, the head 134 and the long hole 210 of the rotor 130 coincide with each other, and then the door 1 in which the male part 100 is completely opened is opened. As shown in FIG. 4, the head 134 of the rotor 130 enters the long hole 210 of the female part 200. Then, as the tip of the push button 150 is pressed in contact with the pressing projection 220, the return spring 154 is compressed and the wing 151 is retracted along the V-shaped groove 132, the wing 151 is The force is transmitted to the pressure plate 114 by pushing the plunger 140 by the pushbutton 150 while retreating from the V-shaped groove 132. Accordingly, as the pressure plate 114 is retracted and the coil spring 111 is compressed, the lifting pin 113 rotates along the rotation guide hole 112, and the lifting pin 113 rotates the rotor 130. At this time, the rotor 130 is rotated by 90 ° because the rotation is terminated when the locking jaw 133 touches the stopper 120b of the outer cylinder 120, and eventually the head 134 is rotated by 90 ° so that the long shaft of the long hole 210 is rotated. It is changed in the direction crossing the direction is caught by the locking jaw 211 of the female portion 200 is in a locked state. At this time, in the process in which the male portion 100 is inserted into the female portion 200, the buffer cylinder 122 contacts the female portion 200 so that the shock absorbing spring 230 is gradually compressed, thereby absorbing the shock.

When the plunger 140 is pressurized, the locking protrusions 141 and 142 are relatively passed through the slots 152 to prevent malfunction of the plunger 140, and the locking protrusions 141 and 142 of the plunger 140 are caught in two stages. It is located in the rear side hole of the ball 115 to maintain the locked state, and immediately after the wing 151 moves over the V-shaped groove 132 toward the adjacent V-shaped groove 132, the push button 150 is rotated 90 ° While advancing to the restoring force of the return spring 154, it returns to the standby state.

When the front end of the push button 150 is pressed by the pressing protrusion 220 as described above, the rotor 130 rotates by 90 ° due to the interlocking action, and thus the head 134 of the rotor 130 on the engaging jaw 211 of the female part 200. ), The door 1 is locked with respect to the wall 2. Therefore, the present invention has a function of temporarily locking the door 1 to the wall 2 so that the strong wind does not close on its own.

And, if you want to close the door (1) If you press slightly toward the wall (2) before pulling the door (1) relatively pressing protrusion 220 to push the push button 150, at this time push button 150 As the retreat along the V-shaped groove 132, the lower end of the plunger 140, that is, the inclined surface 153 presses the locking projection 142, the upper locking projection 141 is moved to the initial position. That is, since the position of the locking protrusion 141 which is caught in the lower long hole of the second locking hole 115 and the position of the slot 152 do not coincide with each other, the push button 150 is pressed, and the locking protrusion is caused by the inclined surface 153. The locking state of the pushbutton 150 is released by pressing 141. At the same time, the elastic force of the coil spring 111, which has been compressed at the same time, acts as the pressure plate 114 and the lifting pin 113 made of the fuselage in the reverse direction at the same time, and at the same time, the rotor 130 rotates by 90 °. . Therefore, the head 134 of the rotor 130 is in a state capable of exiting the long hole 210 without being caught by the latching jaw 211 of the female part 200. At this time, the door 1 may be pulled out and closed. In addition, after the locking state of the plunger 140 is released, the push button 150 is advanced by the restoring force of the return spring 154 and is 90 ° by the wing 151 passing through the V-shaped groove 132 to the initial position. It is reversed to return to the state before the door 1 is fixed, that is, the standby state.
