Description

Cover apparatus for dial lock {Cover apparatus for dial type aid lock}

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 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 devised to solve the problem as described above, it is possible to completely block the operation of the auxiliary lock of the criminals 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.

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

Figure 2 shows a perspective view of the dial-type cover device for the present invention the auxiliary lock, the present invention cover device 100 is formed with a latch handle 20 in the front and the lock release prevention knob 30 is installed 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 significantly deviate 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, the present invention is a coupling hole 111 is formed on one side of the body 10, that is, the concave portion 110 for the coupling of the shaft 120, the spiral portion 121 at the end of the shaft 120 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 accommodating part 131 formed on the cover 130 of the present invention is configured to facilitate rotation of the dial 140 in the accommodating part, and the cover 150 is a configuration necessary to prevent the dial from being separated. In this case, a groove 132 may be formed at one side of the cover 130 to prevent interference between the through hole 133 and the unlocking prevention knob 30 so as to facilitate the coupling of the shaft 120.

As such, 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 the operation of the dial number. It would be.

Therefore, the auxiliary lock provided with the present invention has a structure in which the locking means (A) is released only by manipulating the dial 140 to match a preset number, 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.

As such, the present invention prevents the easy opening and closing of the cover by a dial locking device, making it almost impossible to operate the auxiliary lock through the milk inlet, thereby preventing the crime, and also allowing the cover to move in a sliding manner. And it is a very useful design to facilitate the use by minimizing the interference.
