Locking Cylinder

1 is an exploded perspective view of the present invention.

2 (a) and 2 (b) is a longitudinal cross-sectional view showing the operating state of the present invention during the second.

The present invention is designed to improve the lock, and the conventional locks are formed in one side of the uneven part of the key, so when a key of a similar size is inserted into the lock, instead of its own key, the lock body of the lock may be There was a problem that the lock is released and the lock is released, and in addition to this case, the conventional lock that has been fixed has been frequently released due to the easy release using wires and other iron pieces.

The present invention has been made to solve the problem in consideration of the above-mentioned conventional problems, and the structure, operation and effects by the accompanying drawings in detail as follows.

After intervening a plurality of flow plates 3 each having different lengths and recessed positions of the filth grooves 3 between the diaphragms 5, they are burnt with a sliding shaft 6 that is loaded with springs 6 '. In inserting the rotating body 1 into the cylinder 7 by inserting the fixed disk 1 'into the body 1 and fastening with a bolt 1 ", the inserting piece 4 is rotated. The plurality of flow pieces 3 and the recess 7 'built in the c) are inserted between the cylinders 7 recessed in the inner circumferential surface.

In the figure, reference numeral 2 is a fixing piece, 8 is a key, and 8 'is an uneven portion.

In the present invention, the uneven portion 8 'is inserted into the rectangular insertion hole installed in the fixed disk 1' by pressing the key 8 formed in the bottom portion, and the length and the position of the groove 3 'are respectively different. A plurality of flow plates 3 are each pressed at regular intervals by the uneven portion 8 formed on the bottom of the key 8 and the grooves 3 'recessed at one end of the flow plate 3 coincide with each other. Therefore, the blast furnace in which the insertion piece 4 inserted into the recess 7 ', which is recessed on the inner circumferential surface of the cylinder 7, is inserted into the recess 3' of the flow plate 3 (second (b) in the drawing). The pivot body 1 inserted into the cylinder 7 is rotated as a ratio, so that the unlocking piece of the lock is operated by the sliding shaft 6 which is pivoted so that the unlocking of the lock is achieved. When re-locking the lock, as shown in the above, the pivot body 1 rotated in one direction is formed with a key having an uneven portion 8 '( 8) When rotating in a circular shape using the spring 6 ', the plurality of flow plates 3 piled up with the spring 6' are returned to the original shape, so that each groove 3 'is displaced from each other, and the insertion piece which has been inserted into the groove 3' is inserted. (4) is inserted into the recess 7 'concave on the inner circumferential surface of the cylinder 7 (see also the second (a) in the drawing), so that the rotational body 1 inserted in the cylinder 7 cannot be rotated. The lock is firmly tightened because it is done.

As described above, the press-fitting cylinder of the present invention has a plurality of flow plates having different heights and positions of the recesses and grooves 3 'configured to correspond to the heights and heights of the uneven portions 8' formed at the bottom of the key 8. 3) is interposed between the diaphragm 5, and then mounted firmly on the sliding shaft 6 protruding with the spring 6 ', so that the height of the uneven portion 8' formed at the bottom of the key 8 is increased. In the case where the length of the flow plate 3 does not coincide with each other, the recesses 3 'concave in the plurality of flow waves 3 do not coincide with each other, and thus the grooves 7' concave in the inner circumferential surface of the cylinder 7 Since the rotating body 1 does not rotate from the cylinder 7 by the inserted inserting piece 4, it is impossible to unlock the lock. Also, when a wire and other iron pieces are used as in the prior art, a large number of fluid plates 3 ) Can not be pressed regularly, so the lock can never be achieved, so various interior doors Locks of this set is designed to improve the practical designed with a rugged hanging jeongsangtae and impossible work at all except its own key and superior endurance, and work to correct the equipment used Hebrews.

Claims (1)

After interposing a plurality of flow plates 3 having different lengths and positions of grooves 3 'between each diaphragm 5, the rotating body is supported by the sliding shaft 6 formed by the spring 6'. 1) The inserting piece 4 is inserted into the rotating body 1 in inserting the rotating member 1 into the cylinder 7 by attaching the fixed disk 1 'and fastening with the bolt 1 ". An indentation cylinder for a lock, which is inserted between a plurality of flow plates (3) and recesses (7 ') formed in the inner circumferential surface of the cylinder (7).
