Description

With two sets of variable code locks

A lock with two sets of changing codes, especially a kind of locks with several holes drilled on the key plate respectively to form the first set of changing codes, and at least one outer block is sleeved on the key plate near the handle end to form a first convex Those who have completed the second set of locks with code-changing combination.

The commercially available steel ball lock combination (please refer to Figure 1 and Figure 2) is mainly a lock set completed by rotating the key 1 and inserting it into the key hole 20 of the inner lock core 2 inside the through hole 30 of the outer lock core 3. The design principle is that the key 1 is inserted into the lock core 20. When the key hole 20 of the inner lock core 2 is at the correct position of the check code, the inner bead 50 in the inner bead hole 22 of the inner lock core 2 corresponding to the position 14 of the drilled hole on the key plate 12 of the key 1 and the inner bead hole 22 of the inner lock core 2 and penetrate to the outer bead hole of the outer lock core 3 The outer ball 52 in the middle 32 will be fixed by the plug 56 of the outer ball hole 32, and the spring 54 will be displaced toward the hole 14 by the elastic force, so that the outer ball 52 on the tangent line between the top edge of the inner ball 50 and the hole 3 of the outer lock core 3 is fixed. The bottom edge is aligned with the position of the bead row 5. When the key 1 is rotated, the bottom edge of the outer bead 52 will move in a circular motion around the outer diameter of the inner lock core 2 and will not fall into the inner bead hole 22 of the inner lock core 2 (if the outer bead 52 sinks into the inner bead hole 22) The inner bead hole 22 will be stuck so that the inner lock core 2 cannot be rotated, which is collectively referred to in the industry as the "up-and-down phenomenon". This means that the key 1 can be successfully rotated and the key handle 10 can be successfully and smoothly rotated by aligning the code changing position. The ring groove 24 on the rear side of the lock core 2 is connected with the lock tongue and the door frame is opened to open the door. Since the above lock only provides a set of code changes, the thief can easily open the door and steal with the unlocking tool without the need for the preset key 1 at all. In view of this, after years of research, the present invention is finally developed, and its purpose is to provide a new type of lock with two sets of variable codes, which can only be correctly checked and unlocked by using the expected key 1 of the present invention.

A lock with two sets of variable code, the key 1 of the present invention (please refer to FIG. 3 and FIG. 4) is assembled by the key plate 12 fixed in the key plate hole 15 of the key handle 10, and the two sets of variable code are assembled by the key 1 respectively. A number of holes 14 are drilled on the key plate 12 to form a first set of variable codes, and at least a first protrusion 60 is formed on the two surfaces of the inner lock core adjacent to the key handle 10, and the two surfaces of the inner lock core are formed with equal numbers of matching numbers. A protrusion 60 corresponds to the hole 26 to complete the second set of code-changing locks.

The design of the first protrusion 60 and the corresponding hole 26 is necessary. The matching shape and the length of the first protrusion 60 determine the depth of the key 1 being inserted into the key hole 20 of the inner lock core 2, which is a brand-new code changer design concept.

The second embodiment of the present invention (please refer to FIGS. 8 , 9 and 10 ) is that the cross section of the key handle 10 on the front side of the key 1 provided with a number of screw holes 65 should be larger than that of the key handle 10 and its end surface is provided with a key The through-hole 66 and the corresponding number of screw holes 65 through which the plate 12 passes through the outer stopper 6, wherein, at least one first protrusion 60 is formed on either side of the outer stopper 6 adjacent to the inner lock core 2, and the inner The two faces of the lock core are formed with equal numbers of holes 26 that match the first protrusions 60 , and the key handle 10 and the outer locking piece 6 can be combined to complete the second set of locks for changing codes with the same number of screws 64 . It is detachable and can achieve the function of changing the second set of code at will. For example, the owner of the rental building can replace it by himself before each new tenant moves in to achieve the purpose of mobile code change.

In the third embodiment of the present invention (please refer to FIG. 11 ), at least one first protrusion 60 is formed on either side of the surface of the pivoted outer stopper 6 adjacent to the inner lock core 2 on the front side of the key handle 10 and the mirror If at least equal number of first protrusions 60 with the same shape are formed at the position of the shooting side, the key 1 can be inserted into the key hole 20 of the inner lock core 2 in any direction to open/close.

In the fourth embodiment of the present invention (please refer to FIG. 12 ), at least one first protrusion 60 is formed on either side of the surface of the pivoted outer stopper 6 adjacent to the inner lock core 2 on the front side of the key handle 10 and at other positions At least one first protrusion 60 with different shapes is formed, and the key 1 must be directed to the person inserted into the key hole 20 of the inner lock cylinder 2 to open/close.

The fifth embodiment of the present invention (please refer to FIG. 10 and FIG. 13 ) is that at least one first protrusion 60 is formed on either side of the surface of the pivoted outer catch 6 adjacent to the inner lock core 2 on the front side of the key handle 10 , And the outer side of the first protrusion 60 of the outer block 6 is at least provided with a second protrusion 62, wherein, the outer lock core 3 is formed with corresponding rings 34 that are equal to the first protrusions 60. When the key 1 is inserted, the corresponding ring 34 is formed. When the keyhole 20 of the inner lock core 2 is rotated to unlock, the second protrusion 62 will open/lock in a clockwise or counterclockwise circle in the corresponding ring 34 of the outer lock core 3 .

The fifth embodiment of the present invention (refer to FIG. 4 to FIG. 6 ) is that at least one first protrusion 60 is formed on the two surfaces of the key 1 and the key handle 10 adjacent to the inner lock core 2, and the 2 surfaces of the inner lock core are formed with equal numbers of matching first protrusions 60. A protrusion 60 corresponds to the hole 26 , wherein the inner bead hole 22 is formed at the radial position of the inner lock core 2 relative to the first protrusion 60 where the key 1 is inserted into the key hole 20 , and the outer lock core 3 is also provided with an outer bead hole at the relative position of the outer lock core 3 . The bead hole 32 is for inserting a bead row 5, until the first protrusion 60 of the key 1 has the function of unlocking the core code of the outer top bead row 5.
