Description

Combined lock core Technical Field The invention relates to the technical field of locks, in particular to a combined lock cylinder. Background The lock core is a core component of the lockset and is responsible for controlling the unlocking of the lockset, and a plurality of anti-theft technologies are adopted, and the lock core comprises a plurality of special-shaped anti-pulling marble and precise number marble structures, so that the lock core has high technical unlocking prevention safety performance. With the development of technology, electronic locks have been widely used. When the lock core is installed in the lockset, the existing lock core can be installed only through the screw penetrating through the fixing screw hole of the lock core shell when being installed and fixed. The mounting means is single, is difficult to satisfy convenient quick installation to different screen cabinet tool to lock, needs to change the structure, perhaps changes the lock core, uses and becomes inconvenient. Disclosure of Invention The invention aims to provide a combined lock cylinder, which realizes different installation modes through a first assembly hole on an installation part, a second assembly hole on a lock cylinder shell and an assembly groove, is suitable for various screen cabinet locks and is more convenient to use. In order to solve the technical problems, the technical scheme is that the combined lock cylinder comprises a mounting part, a lock cylinder shell and a lock cylinder piece arranged in the lock cylinder shell, wherein the lock cylinder shell is detachably arranged on the mounting part, the mounting part is attached to the side wall of the lock cylinder shell, a first assembly hole is formed in the side part of the mounting part, and a second assembly hole and an assembly groove for fixing are formed in the side wall of the lock cylinder shell towards the direction of a shaft core. According to the technical scheme, the lock cylinder is inserted into the handle of the lock, the lock cylinder is fixedly installed through inserting the screw into the first assembly hole on the installation part, or the lock cylinder and the handle are fixedly installed through inserting the screw into the second assembly hole and the assembly groove on the side wall of the lock cylinder shell, so that the lock cylinder is convenient and quick to install, is suitable for various screen cabinet locks, and is more convenient to use. The combined lock cylinder is characterized in that the second assembly hole is parallel to the axial lead of the assembly groove. The second assembly hole is parallel to the assembly groove, so that the assembly is conveniently carried out on the same side of the lock cylinder shell when the screw is inserted for fixation. The front end of the lock cylinder shell is extended to form a central bulge, and intelligent chips are sleeved on the central bulge. The intelligent chip can play a dustproof role, and dust is prevented from entering the lock core shell. The combined lock cylinder is characterized in that the lock cylinder shell is provided with a central hole penetrating through the axis of the lock cylinder shell, one end of the central hole penetrates through the central protrusion, and the lock cylinder piece is assembled in the central hole.
