The protection ring 5 is also made of a hardened steel or stainless steel, which is difficult to cut even if it is cut and broken by a sander or the like. This defense ring 5
Has a hollow frusto-conical portion 6 surrounding the front portion of the flange portion 4 of the cylinder lock 1. In addition, the protection ring 5 forms a step 8 in which the flange 4 of the cylinder lock 1 is locked when the cylinder lock 1 is fitted into the hollow portion of the protection ring 5. The hollow portion of the defense ring 5 needs to have a diameter that allows the key of the cylinder lock 1 to be inserted. Further, in order to fit the protection ring 5 into a hole formed in the door 10 and lock the same with the door 10, the protection ring 5 has a cylindrical portion 7 having a diameter smaller than the diameter of the bottom surface of the truncated cone 6, A step 9 is formed.

Next, a method of attaching the lock device of the present invention to the door will be described. First, a hole large enough to fit the cylindrical portion 7 of the protection ring 5 in the door 10 is formed.
Fit. The step ring 9 formed by the truncated cone 6 and the column 7 of the ring 5 locks the ring 5 to the door 10, and welds the back surface of the door 10 to the column 7 of the ring 5 by welding or the like. Stick. Next, the cylinder lock 1 is fitted into the hollow portion of the defense ring 5. The flange 4 of the cylinder lock 1 and the step 8 formed in the hollow part of the defense ring 5 are joined, and the cylinder lock 1 is locked. The cylinder lock 1 is fixed inside the door 10 with screws or the like. Further, it is also possible to fix a protection plate around the back surface of the door 10 in which the protection ring 5 is fitted by welding or the like, and to prevent the circumference of the protection ring 5 from being broken by a drill or the like.

The thickness of the frustoconical portion 6 of the protection ring 5 is such that when the lock device is to be cut and broken by the sander, the sander blade 11 does not directly contact the flange 4 of the cylinder lock 1 and 11 has a thickness that makes it very difficult to pass through the truncated cone 6 of the defense ring 5 and reach the flange 4 of the cylinder lock 1. Even if the frusto-conical portion 6 of the protection ring 5 is cut and reaches the flange 4 of the cylinder lock 1, a considerable amount of time is required, so that the anti-theft performance is sufficient. Furthermore, since the flange 4 of the cylinder lock 1 made of a hard steel material is present inside the truncated cone 6 of the protection ring 5, even if the protection ring 5 is cut and broken, the flange of the cylinder lock 1 is next. The part 4 needs to be destroyed and the antitheft property is extremely high. Further, since the portion protruding above the surface of the door 10 is the truncated cone 6 of the protection ring 5, it is difficult to directly pinch the protection ring 5 with pliers or strike with a hammer or the like.
