The present invention relates to a cover device for the auxiliary lock, in particular by forming a cover device having a locking means on the auxiliary lock formed on one side of the door for preventing criminals from unlocking the auxiliary lock through the milk inlet, etc. It relates to a cover device for the auxiliary lock.

Generally, a milk inlet having a structure penetrating the inside and outside of the door is installed at the lower part of the door of an apartment, a house, etc. so that milk or newspaper deliveries can be put into the house from the outside.

However, in recent years, the criminal act of invading the inside by releasing the lock of the auxiliary lock by inserting the special equipment equipped with the endoscope camera into the milk inlet is rapidly increasing.

Therefore, the Republic of Korea Utility Model Registration No. 0284629 "Secondary lock safety cover" is conceived to solve the above problems, but as shown in Figure 1 cover portion 31 so as to completely wrap the latch handle (20) Is formed and hinged to the subsidiary lock main body 10 and bolted to the subsidiary lock main body through the cover, when the cover is tightened into the subsidiary lock main body, the cover is in close contact with the subsidiary lock main body and the latch handle The operation of the 20 is restrained, and when the auxiliary lock main body 10 is released to the outside, the cover is separated from the auxiliary lock main body and consists of a fixing bolt 40 to enable the operation of the latch handle 20.

However, the cover 30 is simply configured to be fixed by the fixing bolt 40 is rotated, which has the effect of completely closing the latch handle 20 of the auxiliary lock, this also has a special ring formed through the milk inlet Pulling the cover 30 using the equipment is easy to open it will have a closed end can not be maintained.

In addition, since the cover 30 is normally opened to face forward, the inconvenience of the user is increased due to the interference of the cover in the operation of the auxiliary lock.

Therefore, the present invention has been made in order to solve the problem as described above, it is possible to completely block the operation of the auxiliary locks of the offenders through the milk inlet by providing a cover means that is provided with a locking means to be opened and closed slidingly. It is to provide a dial cover device for the auxiliary lock that can minimize the interference and the use space in using the auxiliary lock.

The configuration for achieving the object of the present invention as described above in detail by the accompanying drawings as follows.

Figure 2 shows a perspective view of the dial-type cover device for the auxiliary lock of the present invention, the cover device 100 of the present invention is formed with a latch handle 20 in the front and the body is provided with a lock preventing knob 11 on one side. In the known auxiliary lock consisting of a cover for covering the body 10 and the body, the recess 110 formed to have a predetermined space on the upper side of the body 10, and to be screwed across the recess A shaft (120) formed, a dial (140) for locking and releasing corresponding to the shaft, an accommodating portion (131) and a cover (150) for accommodating the dial (140), and a body ( It is made of a cover 130 to be opened and closed while sliding along the side of 10).

On one side of the outer circumferential surface of the shaft 120, a plurality of key protrusions 121 are formed to protrude, and the dial 140 is formed with an opening and closing groove 142 corresponding to the key protrusion 121. At this time, the key protrusion 121 is formed in different directions to enable the opening and closing by operating the dial 140.

The locking means (A) is most preferably a locking device in the form of a dial 140 as shown in Figure 2, the dial 140 to a known button type locking device within a range that does not deviate significantly from the configuration of the present invention. Of course, it is also possible to form a locking means of various other configurations in addition to the button type.

In addition, in the present invention, a coupling hole 111 is formed at one side of the body 10, that is, at one side of the recess 110, for coupling the shaft 120, and at the end of the shaft 120, the spiral part 121 is formed. Is formed is screwed to the fastening hole 111. At this time, the through hole 112 for insertion of the shaft is formed in the body 10 to facilitate the coupling of the shaft 120.

In addition, the housing 131 formed in the cover 130 of the present invention is configured to facilitate the rotation of the dial 140 in the housing, the cover 150 is a configuration necessary to prevent the departure of the dial. At this time, one side of the cover 130 may be formed with a groove 132 for preventing the interference of the through hole 133 and the unlocking prevention knob 11 to facilitate the coupling of the shaft 120.

As described above, the present invention is engraved on the outer circumferential surface of the dial 140, the numbers are engraved (刻印) and the opening and closing grooves 142 correspond to the corresponding numbers, so that the locking means A can be released by manipulation of the dial number. It would be.

Therefore, the auxiliary lock installed in the present invention has a structure in which the locking means (A) is released only by matching the preset number by operating the dial 140, and the cover can also be opened only when the locking means is released. It is almost impossible to unlock the locking means, open the cover, and then open the auxiliary lock, so that it is possible to maintain a secure lock of the auxiliary lock.

Thus, the present invention is to prevent the easy opening and closing of the cover by the dial-type locking device to make the operation of the auxiliary lock through the milk inlet almost impossible to prevent crime, and also to allow the cover to move in a sliding manner by the user's operation And it is a very useful invention to facilitate the use by minimizing the interference.
