In order to achieve the above object, the anti-theft lock of the present invention is a key retaining groove which is fixed to the key holder inside the lock body into which the key is inserted, the key piece groove is operated in engagement with the groove formed on the outside of the insertion portion of the key Inner grooves are also formed in a spiral shape, an insertion groove is formed on one side of the lock body to insert an external hook hole so that the hook rod can be hooked to the hook hole, and the clasp rod can be raised or lowered on the upper portion of the lock body. A hole is formed and the clasp is fully inserted into the lock body when the lock is locked.

Hereinafter, with reference to the accompanying drawings will be described in more detail the anti-theft lock of the present invention.

1 is a perspective view of an anti-theft lock and key according to a preferred embodiment of the present invention, Figure 2 is a perspective view of a key holder and a key formed inside the anti-theft lock according to a preferred embodiment of the present invention.

As shown, the key 30 is the insertion portion 32 is inserted into the lock is bent in a spiral, the fixing piece 20 formed in the key retainer 18 inside the lock body 10 is also formed bent in a spiral have. Accordingly, although not shown, the grooves (not shown) inside the grooves 18a of the key holder 18 that operate in engagement with the grooves 34 formed outside the insertion portion 32 of the key 30 also form a spiral. Done. The key 30 is inserted into the groove 18a of the key holder 18 inside the lock body 10, and after the groove 34 of the key and the groove (not shown) of the key holder are engaged, the key is rotated. To lock and / or open. When the key 30 is to be inserted into the groove 18a of the key holder 18, the user must insert the key while rotating the key in a predetermined direction. This is because the groove 34 formed outside the insertion portion 32 of the key 30 and the groove inside the groove 18a of the key holder 18 are formed in the helical direction. As such, the lock 100 has a recess formed in the groove 18a of the key retainer 18 so that the recess 32 of the key 30 is not formed so as to fit snugly in the lock. If the groove of the lock key retainer differs from the groove of the key insert, the lock cannot be opened. Therefore, it is impossible to open the lock by using a pin or another mechanism as in the prior art, there is an advantage that theft can be prevented.

On the other hand, the insertion groove 16 is formed on one side of the lock body 10, the hole 14 is formed on the lock body 10. Insertion groove 16 is formed to fasten the clasp 12 of the lock to the hook (50) by inserting the external hook (50), the hole 14 formed in the upper portion of the lock body 10 is a clasp The rod 12 is formed to be raised or lowered. When locking the lock 100, the clasp 12 is completely inserted into the lock body.

3 is a cross-sectional view of the anti-theft lock, in accordance with a preferred embodiment of the present invention. As shown in FIG. 3, after the key 30 is rotated and inserted into the groove 18a of the key retainer 18, the latch rod 12 of the lock is lowered so that the latch rod 12 is the body 10 of the lock. Once fully inserted, rotate the key 30. In this state, when the key 30 is rotated, the lock pin 22 of the lock is caught by the catching groove 24 formed on one side of the clasp 12 so that the lock is locked.

When the lock is to be opened, the key 30 is inserted into the groove (18a in FIG. 2) of the key holder 18 in the same manner, and then rotated. As the spring 26 comes out the clasp 12 is raised upwards.

Figure 4 is a plan view of a conventional hanger in which the lock of the present invention is locked, Figure 5 is a schematic diagram showing the state before and after the anti-theft lock is locked to the hook in accordance with a preferred embodiment of the present invention. 5 (a) is a state before it is caught, and (b) is a state after it is caught.

The lock 100 of the present invention is locked by being locked to a conventional general hook 50 fixed to the door 40. Referring to (a) and (b) of FIG. 5, a method of fixing the lock 100 of the present invention to the hook 50 is as follows. First, as shown in (a) of FIG. 5, the outer hook 50 is inserted into the insertion groove 16 of the lock 100, and then the lock rod 12 is lowered using a key in a state of being lowered. Will be locked. When the lock 100 is locked to the hook 50, the clasp does not protrude outward so as to be completely inserted into the lock body, and the lock 100 is in close contact with the door 40. As a result, criminals such as thieves cannot cut the clasps using a hacksaw or the like.
