Description

An apparatus for locking a thing's drop twice}

The present invention relates to an inlet lock device, and more particularly, by double-closing the inside and the outside of the inlet in order to prevent theft accident using the inlet formed through the inside or outside of the building's wall or home front door. It relates to an inlet double locking device to ensure safety.

In general, the front door of the apartment, etc. is formed with a small article opening of a circular cross section penetrating the inside / outside to put the newspaper or milk into the room while it is closed. However, theft accidents frequently open the front door through the entrance using a predetermined tool and steal valuables left in the house by outsiders. Therefore, a locking device that can block this inlet in the room has been developed. One example of a typical inlet lock device is shown in FIG. 1 below.

Figure 1a is a perspective view showing a conventional inlet lock, Figure 1b is a partially enlarged perspective view showing in detail the inner portion of the locking device shown in Figure 1a.

At one side of the inlet 12 of the front door 10, the cover plate 122 is rotatably fixed to an upper end thereof, and an outer support member 120 having an inner diameter corresponding to the diameter of the inlet 12 is located. The outer support member 120 is provided with four protrusions 126 contacting the inner surface of the inlet 12 on one surface thereof, and screw holes 128 having a predetermined depth. On the other side of the inlet 10 is formed a cylindrical flange 112 on one surface, and four projections 114 are formed in each of the insertion hole 115 corresponding to the screw hole 128 in the inner circumference The hollow inner support member 110 is located. The other side of the inner support member 110 is provided with an inner locking hole 116 is formed at the bottom, the disk-shaped blocking plate 140 is hinged by the round bar pin 118 at the top. As shown in FIG. 1B, a lower portion of the blocking plate 140 is moved upward and downward through a spring (not shown) mounted therein so that a lower end portion thereof can enter and exit the locking hole 116. The plate lock 142 and a predetermined release piece 144 for releasing the locked state are formed. The inner support member 110 and the outer support member 120 are coupled by a long bolt 130 that is a fastening member after one end connected to each other at the inside / outside the inlet 12 of the front door 10 is connected.

In the conventional inlet having the above-described structure, the cover plate fixed to the outer support member 120 is not provided with a separate locking device can be easily opened through the cover plate 122 is flipped to one side, the inside Block plate fixed to the support member 110 is to be able to close or open the inlet 12 from the inside, as needed by the lock. That is, when the user presses the upper end of the engaging piece 142 of the lock formed on the cover plate 140 with a finger, the lower end portion protrudes downward and is inserted into the locking hole 116 to lock the inner blocking plate 140. On the contrary, when the release piece 144 is pressed in the locked state, the catching piece 142 is elastically restored by a spring mounted therein, and the lower end part is separated from the catching hole 116 while moving upward, thereby preventing the inner side blocking plate ( 140 is released.

However, in the conventional blocking device, the locking device is provided only on the inner blocking member, so that only the inner side of the inlet can be closed, but the locking device of the inner blocking member is often easily damaged by an impact or the like. There was a problem that was difficult to maintain more consistently. In addition, when only the inner barrier plate is locked with a lock, the cover can be opened, and the cover is opened, and then a wooden bar or metal rods are put in, and a block board made of plastic material is usually broken and inserted into the inside to release the lock to unlock the door. The lock was not enough to prevent theft.

Therefore, the present invention has been devised to solve the above-mentioned drawbacks, and it is possible to close the inside and the outside of the inlet twice in order to prevent various theft accidents using the inlet formed to pass through the inside and outside of the building's wall or home front door. It is an object of the present invention to provide an inlet double lock.
