Problems solved by technology

Since the size of the large and small sliders in the axial direction of the lock body is small, if the lock body is very long, it is necessary to increase the length of the inner lock cylinder or the outer lock cylinder, and it is difficult to ensure the inner and outer lock cylinders in processing. Cylindricity, when the key is used to drive the lock cylinder to rotate, there will be a stagnation phenomenon between the lock cylinder and the lock head body, the rotation of the lock cylinder is not flexible, and it is inconvenient to open

Abstract

The invention relates to a locking cam of a lengthened safe-guard door lock. The structure is as follows: the locking cam comprises a locking cam body provided with a lock core hole, a lock core and a connection body which are arranged in the lock core hole and mutually connected, wherein, the connection body is simultaneously connected with a shifting block on the locking cam. The locking cam ischaracterized in that a movable connecting mechanism which connects the lock core and the connection body is arranged between the lock core and the connection body, the connecting mechanism can move radially corresponding to the lock core. On one hand, as the connecting mechanism has certain length, the lock core needs not to be very long, thus facilitating control of mismachining tolerance of the lock core, on the other hand, when the lock core hole in the locking cam body is very long, the connecting mechanism can move, thus reducing part of the mismachining tolerance of the lock core hole and further facilitating the lock core to rotate flexibly.

Description

technical field [0001] The invention relates to a lock head for assembling on an anti-theft door lock, in particular to a lengthened lock head of an anti-theft door lock. Background technique [0002] Anti-theft door locks are generally unlocked by rotating the lock cylinder in the lock head with a key. Due to the increasing thickness of the current anti-theft door, the lock head assembled on the anti-theft door lock is also lengthened accordingly, which increases the difficulty of production and process, and the quality cannot be guaranteed. This is also a headache in the lock industry. . Such as Chinese patent: 200420114615.9 discloses a kind of lock end of existing structure. Its structure includes the lock head body, the inner and outer lock cylinders coaxially arranged in the lock head body, and the small slider and the big slider which are axially hinged together are arranged between the inner and outer lock cylinders in the lock head body. block, large and small sl...
