An extension tube 4 inserted into the formed coupling hole 8, a locking bar 3 extending in the same direction from the end of the extension tube 4 and to which a locking piece 2 serving as a latch is fixed, and a door (D) is formed to protrude from the rear surface of the case so as to be coupled to the auxiliary coupling hole (8a) formed through the front of (D), the end portion has a screw hole formed in the coupling base (6), and the screw hole of the coupling base (6) It is configured to include a fixing screw (7) to be screwed, and a fixing nut (4b) screwed to the screw thread (4a) of the extension tube (4).

According to this configuration, when the dial lock (1) is coupled to the door (D), first, the coupling hole (8) and the auxiliary coupling hole (8a) are formed in the door (D), and the extension tube (4) is coupled. In the hole 8, the coupling base 6 is inserted into the auxiliary coupling hole 8a, respectively.

In addition, at the rear side of the door D, the fixing nut 4b is screwed to the screw thread 4a of the extension tube 4 and rotated until the rear surface of the door D is pressed.

Finally, in the lower part of the case, the fixing screw 7 is coupled to the screw hole of the coupling table 6 to be fastened.

However, according to Patent Document 1 having such a configuration, there is a disadvantage in that the coupling operation itself is cumbersome because it is necessary to form the auxiliary coupling hole 8a in addition to the coupling hole 8 in the door D.

That is, the door (D) is formed with the coupling hole (8) and the auxiliary coupling hole (8a), but precisely drilled to fit the position of the extension tube (4) and the coupling table (6) in the field, and the horizontal of the dial-type lock. It is not easy to maintain the correct position, and if the position and level are slightly displaced, there is a disadvantage that it is not easy to perform the coupling operation because it must be drilled again.

Moreover, when additional work is performed by incorrectly determining the position of the auxiliary coupling hole 8a, there was a problem that the door D was inevitably damaged, and the auxiliary coupling hole 8a formed incorrectly on the rear surface of the door D was exposed. In the case, there was a disadvantage that was not good in appearance.

It is configured to include a latch unit 700 installed to be able to rotate relative to the guide hole 620.

According to this configuration, after inserting the coupling pipe portion 400 extending vertically from the rear surface of the case 100 into the mounting hole D0 of the door D, the fixed body 500 from the rear side of the door D ) Is coupled to the coupling pipe part 400, and the coupling support part 600 is coupled to the coupling pipe part 400 in a state in which the coupling support part 600 faces one surface of the fixed body 500, and then the coupling hole 610 and the coupling hole By fastening to the door D with a screw F or the like through 510, the rotary lock assembly 1000 may be firmly fixed to the door D.

Therefore, it is very easy to fix and install the rotary lock assembly 1000 to the door D.

In addition, the door D is not formed with any hole or groove for mounting other than the mounting hole D0, so that the door D is not damaged or the exterior is not damaged.

In order to couple the fastening support part 600 to the coupling pipe part 400, the fastening support part 600 has a cylindrical inner circumferential surface in which a first thread 631 is formed, and the rotation guide hole 620 is formed at the bottom. A fixing groove 630 may be formed, and a second screw thread 431 may be formed on an outer circumferential surface of the coupling pipe part 400 in which at least a portion of the circumferential direction is screwed to the first thread 631.

Accordingly, when the fixing groove 631 of the fastening support part 600 is aligned with the coupling pipe part 400 and then rotated, the fastening support part through the relative movement of the first screw thread 631 and the second screw thread 431 It moves until 600 is in close contact with the rear surface of the door D.
