* Explanation of symbols for main parts of the drawings

(4): fixed pin

The present invention has been devised to solve the above-mentioned drawbacks. The present invention is divided into two to four equal parts of a cylindrical rotary body with a key insertion hole horizontally, so that the rotary body is inserted into the key insertion hole with a wire, an awl, or a flat iron piece. Even if the pivoting pin is correct, the pivoting body rotates. In this case, even if the first pivoting part is slightly rotated, if the key insertion hole of the second rotational body and the key insertion hole of the first rotational body do not coincide, the second rotational body is not rotated. Even if it is rotated together, the third rotating body is separated and can not be easily solved so that it is difficult to make a fastening and takes a lot of time, which will be described in detail with reference to the accompanying drawings.

Like a known lock, a cylindrical pivot is inserted into the lock body, a key insertion hole is installed in the center of the pivot, and a plurality of anchor pins are spring-loaded in the through holes drilled on one or both sides of the pivot. In this case, two cylindrical rotating bodies are formed, one or more through-holes are installed in the rotating body 1, and the fixing grooves 3 and through-holes are installed in the rotating body 2, and the fixing grooves 3 are shot by springs. By inserting the fixing pin 4, it is a structure of a lock that may form a plurality of rotating bodies, as in the other embodiments of the present invention shown in Figure 4 (b) and 4 (c).

(1 ') (1' ') is the rotating body, (5) (5') (5 '') and (6) (6 ') are through-holes, 7 is the key, 7a, 7b, 7c, 7d , 7e, 7f are key grooves keyed to the key.

The present invention composed of such a structure is inserted into the rotating body (1) and the rotating body (2) in turn in the lock body and the fixing pin (4) is spring-loaded in the fixing groove (3) cut on one side of the rotating body (4) When inserting the), the rotating body (2) does not fall out, and when fastening, the locking pin is not unlocked unless the position and size of the locking pin coincide with the key grooves provided on one or both sides of the key. In the present invention, the rotating body (1) (2) is composed of two or more, when fastening with a wire, awl, or flat iron pieces, the rubbing pins of the first rotating body (2) coincide with the rotating body (2). Even if the second rotating body (2) is configured separately from the rotating body (1), do not rotate, and once the rotation body (2) is slightly rotated by the fastener, the key insertion hole is staggered, so that the second rotating body (1) Wire, auger and iron on key inserter The result soejil equipment such can no longer be inserted.

As shown in Figs. 4 (b) and 4 (c) in the above manner, by installing a plurality of rotating bodies, the fastening is extremely difficult, and the fastening takes a long time, and thus can serve as a complete lock. There is a working effect.

Claims (1)

As shown in the figure, a plurality of cylindrical pivots 1, 1 ', 1' ', 2 are sequentially placed in the body of the lock, and the fixing recess 3 is cut in the support of the pivot 2 to spring Lock by inserting the fixing pin (4) shot by.
