As shown in FIG. 1B, a lower end portion of the ring engaging hole 116 is moved upward and downward through a spring (not shown) mounted therein at a predetermined position under an outer surface of the cover plate 140. The lock ring 142 is formed to be retractable, and a predetermined release button 144 for releasing the locked state is formed. The inner blocking member 110 and the outer blocking member 120 are fastened by a long bolt 130 which is a fastening member after one end facing each other inside and outside the inlet 12 of the front door 10 is connected.

In the conventional blocking device having the above-described structure, the outer blocking member 120 is not formed with a separate locking device, the outer side of the inlet 12 easily through the cover plate 122 is flipped to one side. On the other hand, the inner blocking member 110 is provided with a locking ring 142 and a release button 144 for releasing the cover plate 140 hingedly coupled therein. The inlet 12 may be closed or opened. That is, when the user presses the upper end of the locking ring 142 formed on the cover plate 140 with a finger, the lower end portion protrudes downward and is inserted into the hooking hole 116 so that the inner blocking member 110 is formed.

Is released.

However, in the conventional blocking device, since the locking device is formed only on the inner blocking member, only the inner side of the inlet can be reliably closed, and the locking device of the inner blocking member is often damaged by an impact or the like, so that the closing state of the inlet can be maintained more continuously. There was a problem that is difficult to maintain.

In addition, when the blocking device is applied to the home front door, the landlord must go through the trouble of locking and releasing the lock device every time, as well as if the landlord goes out or left without locking the lock of the inner blocking member. There were many problems that were difficult to properly prevent the theft accident.

An object of the present invention to solve the above problems is to block the inside and the outside of the entrance to double closing to prevent various theft accidents using the entrance formed to pass through the inside and outside of the building wall or home front door.
