Detailed Description
It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in fig. 1 to 3, a lock cylinder 10 of the present invention includes a housing 11 and a cylinder core 12 disposed in the housing 11. The cylinder 12 includes an upper cylinder 100, a middle cylinder 200, and a lower cylinder 300, which are sequentially nested. An authorization assembly 600 is arranged between the upper lock core 100 and the middle lock core 200 and used for locking and limiting the upper lock core 100 and the middle lock core 200; when the lock core is locked, the authorization component 600 limits the axial rotation of the upper lock core 100 and the middle lock core 200, so that the upper lock core 100 and the middle lock core 200 are kept in locking linkage; when the lock cylinder is unlocked, the unlocking key 20 provides an authorization acting force to drive the authorization assembly 600 to act, and the locking linkage between the upper lock cylinder 100 and the middle lock cylinder 200 is released.
A clutch mechanism 500 is arranged between the middle lock core 200 and the lower lock core 300 and is used for clutch connection of the upper lock core 100 and the lower lock core 300. When the lock core is locked, the upper lock core 100 axially rotates under the action of external acting force, such as the rotating force of an unmatched unlocking key, the rotating force of tools such as an electric drill and the like, so as to drive the middle lock core 200 to rotate, and the middle lock core 200 drives the clutch mechanism 500 to act, so that the upper lock core 100 and the lower lock core 300 are in a separated state, and the lock core is idle. When the lock core is unlocked, the authorized acting force of the unlocking key 20 releases the locking linkage of the upper lock liner 100 and the middle lock liner 200, the unlocking key 20 is rotated to drive the upper lock liner 100 to axially rotate, the middle lock liner 200 is in a static state, the clutch mechanism 500 enables the upper lock liner 100 and the lower lock liner 300 to be in a linkage state, and the upper lock liner 100 drives the lower lock liner 300 to axially rotate, so that the lock core is unlocked.
When the unlocking key 20 is correct and authorized, the lock cylinder 10 of the invention releases the locking limit between the upper lock cylinder 100 and the middle lock cylinder 200 through the authorization assembly 600. The middle cylinder 200 cannot be interlocked with the rotation of the upper cylinder 100, and the middle cylinder 200 is in a stationary state in the housing 11 of the lock cylinder 10, and cannot drive the clutch mechanism 500 to operate, and cannot keep the upper cylinder 100 and the lower cylinder 300 in a separated state. At this time, under the connection of the clutch mechanism, the upper lock cylinder 100 and the lower lock cylinder 300 are in a linkage state, and the lower lock cylinder 300 is linked with the upper lock cylinder 100 by rotating the upper lock cylinder, so as to realize the unlocking of the lock cylinder.
When the unlocking key 20 is incorrect, unauthorized or a dismantling tool such as an electric drill is violently dismantled, the lock cylinder 10 enables the upper lock core 100 and the middle lock core 200 to keep linkage through the authorization assembly 600. The rotation of the middle lock core 200 can drive the clutch mechanism 500 to operate, and the upper lock core 100 and the lower lock core 300 are separated from each other and cannot enter the interlocking state. At this time, the upper cylinder 100 and the middle cylinder 200 idle in the housing 11, and a rotational force cannot be applied to the lower cylinder 300, and technical unlocking or forced unlocking cannot be achieved. By the design, the lock cylinder 10 realizes idling when the unlocking key is incorrect or unauthorized, unlocks when the unlocking key is correct and authorized, and prevents the key and the lock cylinder from being damaged when the unlocking key is incorrect or unauthorized. Meanwhile, the lock cylinder of the idle lock cylinder is not fixed, an electric drill has no contact point, violent damage is difficult, and the drilling resistance of the lock cylinder is improved.
