The rotor of the lock of the present invention is divided into a lattice shape and the corresponding key is also formed into a lattice shape, making it difficult to unlock with other keys, and at the same time, it is possible to see the lock state. It's about a lock to secure.

Conventional locks are made of “ㅗ” type keyholes in the rotor, and the ball insertion holes drilled in the narrow surfaces on both sides put a coil spring in the ball and the presser cap and secure it with a stopper. (Notice: 82-1087 ), Although it is effective to safely insert the ball and the housing tube on the narrow side of the lock, there is a disadvantage that the key insertion groove for inserting the key cannot be safely secured, and the key insertion hole of the rotor Is known as a lock (notice: 81-188) to secure the stability of the lock by making the key in the form of "+" or "Y" and forming the key correspondingly. There is a drawback that it is easy to imitate the key required for unlocking because it is constantly being inserted into the door.

The present invention devised to solve these various drawbacks, the gland for opening the key insertion dog to the rotor in a lattice shape, but the horizontal axis of the construction is inserted into the horizontal axis of the key so that the rotor can rotate, the bell open Since the construction is divided into a plurality of upper and lower plural, the key formed in the "+", "Y", and "-" shape cannot enter into the construction. Accordingly, when the cross-stitcher is additionally intervened in any one of the deterrents, it is relatively safer than the conventional one. Open the key for the key (2) into the rotor (1), and open the top, bottom, left, and right side dry (3) one row and the end dry (4) (4 ') two open vertically In (4) and (4 '), the chain holes (5) and (5') are provided in a plurality of up and down directions, and the chain holes (5 ") are drilled as needed on any one side of the left and right transverse holes (3). can do.

In this way, in the key (2) to the inside of the key construction (4) (4 ') and the transverse construction (3), a row of transverse sea (7) horizontally protrudes, and as a bell two sea vertical sea ( 8) (8 ') are protruded. In the stator 6, the lock chamber 9 is provided so as to correspond to the lock holes 5 and 5 'of the rotor 1, and then inside the lock chamber 9, the coil spring 10 and the lock holder 11 are provided. ) Is inserted into the chain hole (5) (5 ') of the rotor 1, the drive pin 12 is inserted into the rotor 1 is inserted into the stator (6).

The present invention constituted as described above allows the rotor 1 to be inserted into the stator 6 so that the chains of the driving pin 12 and the stator 6 are inserted into the chain holes 5 and 5 'of the rotor 1. The crystallization 11 inserted in the chamber 9 contacts each other and is released by the driving action of the driving pin 12. (7) must be entered, and the vertical and vertical lines (8) and (8 ') of the key (2) must be correctly entered into the vertical and vertical rows of vertical construction (4) and (4'). The general key consisting of the Y-shape or the "-"-shape does not allow the construction (4) (4 ') (5) to be fitted and no unlocking is possible, so above all, it is possible to maintain the safety of the locked state. Also in the process, since there is no difficulty compared with the conventional lock, imitation is extremely difficult, and a precise lock can be obtained.

Claims (1)

The rotor 1 is divided into two rows of up, down, left, and right side dry holes (3) and two end dry holes (4) and (4 ') so that a plurality of chain holes (5) (5') (5 ") are provided. It is arranged on either side of the final construction (4) (4 ') or the horizontal construction (3), and the key (2) also protrudes one row of transverse wells (7) and two vertical longitudinal ships (8) (8') Lock.
