The lock cylinder construction of the present invention can be mounted to the body of any lock, such as for automotive locks, locomotive locks, bicycle locks, safe locks, etc., therefore, the description only refers to the structural fit of the lock cylinder. 1 to 6, the lock cylinder 10 includes a hollow cylinder 12 having an inner chamber 22; two independent shaft rotating bodies, that is, an upper shaft rotating body 14 and a lower shaft rotating body 16; 18. The upper shaft swivel 14, the lower shaft swivel 16 and the blocking body 18 have a circular cross section, and the cylinder 12 has a first end 20 and a second end 21, from the first end 20 to the second end. The 21 is formed with an inner chamber 22, and the cylinder 12 is provided with a plurality of holes 24 extending from the outer peripheral surface 26 to the inner chamber 22.

The upper shaft swivel 14 is housed in the inner chamber 22 of the cylinder 12 and is rotatable, and is provided with a key inlet 28 and a first passage 30 extending with a cross-shaped cross section, and the outer surface of the inlet 28 is additionally provided. A reference point 31 is provided for the key 40 to be aligned and easily inserted into the first passage 30.

The lower shaft swivel 16 is also placed in the inner chamber 22 and is rotatable, and is also provided with a first inlet 34 and a second passage 36. The second passage 36 is vertically aligned with the first passage 30, more specifically The cross-section of the second passage 36 and the first passage 30 are identical.

a blocking body 18 which is fixed to the inner chamber 22 of the cylinder and cannot be rotated. The most important feature is that the blocking body 18 is fixed between the upper shaft rotating body 14 and the lower shaft rotating body 16, A through hole 50 is formed, and the through hole 50 is formed with a third passage 52 having a cross shape. The third passage 52, the second passage 36, and the first passage 30 are formed to be the same along the central longitudinal axis. The cross-section shape allows the legitimate key 40 to be inserted.

The most important design feature of the present invention is that a blocking body 18 can be accommodated in the inner chamber 22 and between the upper shaft rotating body 14 and the lower shaft rotating body 16, and the blocking body 18 is fixed in the inner chamber. 22 does not rotate, and both the upper shaft swivel 14 and the lower shaft swivel 16 rotate. The blocking body 18 is provided with a through hole 50 and a through third channel 52. The blocking body 18 is further provided with a positioning hole 54 for the pin body 58 to pass through the positioning hole 27 of the cylinder 12 and the blocking body 18. The positioning hole 54 allows the blocking body 18 to be fixed to the cylinder 12. The through hole 50 of the blocking body 18 can provide the second length of the tooth row 47 of the key and enter the second passage 36 of the lower shaft rotating body 16, and the neck portion 48 of the key 40 is located in the through hole 50 of the blocking body 18, thus The first segment 30 of the key 40 is located in the first channel 30 of the upper shaft swivel 14 and the second segment 47 of the key 40 is located in the second passage 36 of the lower shaft swivel 16, and the key 40 is rotated to connect The upper shaft rotating body 14 and the lower shaft rotating body 16 are rotated simultaneously.
