It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

In one embodiment, please refer to fig. 1, which provides an adaptive lock cylinder, including an unlocking assembly, an elongated complementary member 17, a pulling lug 18 and a lock tongue, wherein the unlocking assembly is detachably connected to the elongated complementary member 17, the unlocking assembly is connected to the pulling lug 18, the pulling lug 18 is connected to the lock tongue, the unlocking assembly, the elongated complementary member 17 and the pulling lug 18 are axially arranged, when the elongated complementary member 17 is connected to the unlocking assembly, the length of the adaptive lock cylinder includes the sum of the lengths of the unlocking assembly, the elongated complementary member 17 and the pulling lug 18 in the axial direction, and when the elongated complementary member 17 is not connected to the unlocking assembly, the length of the adaptive lock cylinder includes the sum of the lengths of the unlocking assembly and the pulling lug 18 in the axial direction. The user drives through the subassembly of unblanking and dials and drags 18 rotations, dial and drag 18 and drive the spring bolt, can realize unblanking, add long complement 17 and can dismantle with the subassembly of unblanking and be connected, when the thickness of door is great, can adorn with adding long complement 17, add long lock core specification length, when the thickness of door is less, can dismantle with adding long complement 17, shorten lock core specification length, thereby make door or other devices of the different thickness of adaptation lock core can be nimble, the application range of adaptation lock core has been enlarged, the convenience in use of adaptation lock core has been improved.

Specifically, the subassembly of unblanking is the device that is used for to the adaptation lock core unblock, supplementary completion action of opening the door. The pulling and pulling device 18 is connected with the unlocking component and the lock tongue, the lock tongue can extend out or retract into the adaptive lock cylinder under the driving of the unlocking component, and when the lock tongue extends out of the adaptive lock cylinder, the door and the door frame are locked together, so that the door cannot be opened. When the lock tongue is retracted into the adaptive lock cylinder, the adaptive lock cylinder is in an unlocked state, and a user can smoothly open the door. The shape of the lock tongue is not unique, for example, the lock tongue can be an oblique lock tongue, a square lock tongue, an anti-sawing lock tongue, a double-hook lock tongue and the like, the lock tongue is usually a metal lock tongue, and the metal lock tongue has high strength, is not easy to damage and has long service life.

The structure of the unlocking assembly is not exclusive, please refer to fig. 1, taking the unlocking assembly comprising the lock cylinder 2 as an example, the lock cylinder 2 is connected with the pulling lug 18. A key hole is formed in the lock cylinder 2, and the key 1 is inserted into the unlocking assembly from the key hole to serve as a basis for unlocking and opening the door subsequently. More than two blades are arranged in the lock cylinder 2, each blade is combined to form a specific shape, when a key hole of the lock cylinder 2 is inserted into the matched mechanical key 1, the shape of each blade is matched with the shape of the matched mechanical key 1, the lock cylinder 2 is unlocked, a user can rotate the lock cylinder 2 by rotating the key 1 or other modes, the lock cylinder 2 rotates to drive the poking and dragging 18 to rotate, the poking and dragging 18 drives the lock tongue to retract into the adaptive lock cylinder, the adaptive lock cylinder is unlocked, and the user can complete door opening operation by pushing or pulling a door. It is understood that in other embodiments, the unlocking assembly may have other structures, and the corresponding connection relationship and workflow are adjusted accordingly, as long as those skilled in the art can realize the unlocking assembly.

The subassembly of unblanking can be dismantled with extension complement 17 and be connected, means that extension complement 17 can be in the same place with the subassembly of unblanking is connected, and the adaptation lock core includes extension complement 17 this moment. The extension piece 17 can also be detached, and the adapting lock cylinder does not comprise the extension piece 17. The manner of opening the detachable connection is not exclusive, and may be, for example, a threaded connection, a key connection, a pin connection, or a rivet connection, and may be selected according to actual requirements. The unlocking assembly, the lengthened supplementary piece 17 and the pulling lug 18 are axially arranged, that is, the central axes of the unlocking assembly, the lengthened supplementary piece 17 and the pulling lug 18 are on the same straight line, and the direction of the central axis is also the extending direction of the whole adaptive lock cylinder from the inside to the outside of the door. The lengthening supplementary piece 17 is used for increasing the length of the adaptive lock cylinder, when the lengthening supplementary piece 17 is connected with the unlocking assembly, the length of the adaptive lock cylinder comprises the sum of the lengths of the unlocking assembly, the lengthening supplementary piece 17 and the pulling piece 18 in the axial direction, and when the lengthening supplementary piece 17 is not connected with the unlocking assembly, the length of the adaptive lock cylinder comprises the sum of the lengths of the unlocking assembly and the pulling piece 18 in the axial direction. The length of the extension piece 17 is not unique, and the thickness of the door matched with the lock cylinder and the length of other devices matched with the lock cylinder can be adjusted according to requirements. The type of the lengthened patch 17 is not unique, for example, the lengthened patch 17 may be made of metal, the lengthened patch 17 of metal has high hardness and high strength, and is not easy to be damaged, and the lengthened patch 17 of metal also contributes to prolonging the service life of the adaptive lock cylinder.
