[0008] Preferably, a locking pin is sleeved on the square rod.

[0009] Compared with the prior art, the lock core clutch mechanism of the present invention controls the drive rod to match or separate with the base of the drive mechanism through the connecting rod after the key is inserted into the lock cavity. When matched, the lock can be unlocked through the handle mechanism, and when separated, the lock cannot be unlocked through the handle mechanism. The lock core clutch mechanism has a simple structure, is easy to unlock, and has high safety performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a three-dimensional schematic diagram of the lock cylinder clutch mechanism of the present invention.

[0011] Figure 2 It is a cross-sectional view of the lock cylinder clutch mechanism of the present invention. DETAILED DESCRIPTION

[0012] The present invention is further described in detail below with reference to the accompanying drawings.

[0013] like Figure 1 to Figure 2As shown, the lock cylinder clutch mechanism includes a lock cylinder 1, a handle mechanism 2 and a driving mechanism 3. The lock cylinder 1 and the driving mechanism 3 are arranged on both sides of the handle mechanism 2. The lock cylinder 1 includes a key 11, a lock cavity 12 and a connecting rod 13. The handle mechanism 2 includes a housing 22 and a driving rod 21 accommodated in the housing 22. The driving rod 21 is square. The driving mechanism 3 includes a base 31, a square rod 32 embedded in the base 31 and a spring 33 arranged at the end of the square rod 32. The end of the connecting rod 13 extends into the housing 22 and is inserted into the end of the driving rod 21. Both ends of the driving rod 21 are provided with grooves, and the grooves are square. One end of the spring 33 abuts against the end of the square rod 32, and the other end of the spring 33 cooperates with the groove of the driving rod 21. The end of the connecting rod 13 cooperates with the groove at the end of the driving rod 21. A lock pin is sleeved on the square rod 32. The lock pin can be extended and retracted by driving the square rod 32 to achieve locking or unlocking. A torsion spring is sleeved on the end of the square rod 32.

[0014] When the key 11 is inserted into the lock cavity 12 and turned, the connecting rod 13 rotates and pushes the driving rod 21 to move toward the driving mechanism 3. The driving rod 21 compresses the spring 33 and enters the base 31. The base 31 is provided with a square cavity that matches the driving rod 21. Turning the handle mechanism 2 can drive the square rod 32 to rotate, thereby driving the lock pin to extend and retract.

[0015] The handle mechanism 2 is rotated, and when the handle mechanism 2 is rotated, the driving rod 21 drives the square rod 32 to rotate, and when the square rod 32 is rotated, the locking pin is retracted.

[0016] Therefore, the square rod 32 can be rotated to drive the base 31 and the lock cavity 12 to rotate by rotating the driving rod 21. A lock pin is connected to the square rod 32, and the door lock can be opened by rotating the base 31 and the lock cavity 12.

[0017] When locking the door, the handle mechanism 2 is released, the torsion spring drives the square rod 32 to rotate and drives the lock pin to extend and lock, the key 11 rotates in the opposite direction to reverse the connecting rod 13 and the drive rod 21 is pulled out of the square cavity of the base 31 under the action of the spring 33. After the lock pin on the lock cavity 12 is locked, since the drive rod 21 has been separated from the square cavity of the base 31, the rotating shell 22 cannot drive the square rod 32 to rotate to retract the lock pin and unlock.

[0018] The lock cylinder clutch mechanism of the present invention controls the drive rod 21 to match or separate with the base 31 of the drive mechanism 3 through the connecting rod 13 after the key 11 is inserted into the lock cavity 12. When matched, the lock can be unlocked by the handle mechanism 2, and when separated, the lock cannot be unlocked by the handle mechanism 2. The lock cylinder clutch mechanism has a simple structure, is easy to unlock, and has high safety performance.

[0019] Finally, it should be noted that the above embodiments only illustrate the technical solutions of the present invention, rather than limiting it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
