A hidden dial number lock which opens and closes a number or a letter of a circular disk in which numbers or characters are written on the outside in a rotational combination, characterized in that it comprises a lock (I) or a lock lock A disk 20 having at least two or more rings 10 and a display portion 22 having a disk groove 21 therein and engraved with numbers or letters on the outside thereof; A flange protrusion 31a which is coupled to the inside of the disc 20 and protrudes to be engaged with the disc groove 21 is provided on the outside and a flange protrusion 31a And a flange protruding portion 31b which is engaged with the inside of the disc 20 and protrudes to be engaged with the disc groove 21, , Internal phase Of the second flange of the donut shape and the same number of the display section 22, a flange groove (32b) is provided so that access to the lock projection (11) (30b); A main body portion 40 constituted by a lock ring engagement portion 41 to which the lock ring 10 is coupled, a lock ring separation preventing portion 42 and a disk engagement portion 43 to which the disk 20 is coupled; Wherein the lock is a hidden dial number lock.

5a is a top view showing a coupling relationship between the lock ring 10 and the disc 20 and the first flange 30a and b is a view showing the state of the lock ring 10 and the disc 20 and the second flange 30b, And c is a top view of still another embodiment showing the coupling relationship between the lock ring 10 and the disk 20 and the second flange 30b. Referring to FIG. 1, the flange groove 32b is formed so as not to overlap with the lock projection 11. It is also possible to remove the second flange 30b and engage the body portion 40 so that the disk 20 can rotate.

The second flange 30b is a dummy flange which is independent of the release of the lock by the plurality of flange grooves 32b and is independent of the release of the lock regardless of the number of the disk 20 to which the disk 20 is coupled. Thereby, a total of four discs 20 are provided by combining two first flanges 30a and two second flanges 30b in order, and numbers 0 through 9 are engraved on the display unit 22 For example, When the disk 20 is in the upper side and the flange grooves 32a of the first flange 30a are aligned in the order 1 and 2 respectively, the third and fourth disks 20 are connected to the dummy disk 100 Password combination is possible. Accordingly, even if the password is seen from the outside, it is difficult to grasp the clear password because the number of combinations is large.
