Description

fixed lock

technical field

The utility model relates to a lock, in particular to a fixed lock that can lock a linkage rod by means of a plurality of lock cores.

Background technique

Common locks used on doors include horn locks and multi-stage locks, such as the "lock operating mechanism" of Taiwan Patent No. M441009 and the "multi-stage bolt toggle structure" of M273604. The two opposite ends of the body are respectively provided with a rotatable trumpet-shaped handle, and a lock cylinder is arranged in one of the aforementioned handles. The lock cylinder part is also provided with a lock hole outside the handle, and the key is inserted into the lock hole At this time, the lock key can be used to rotate to drive the lock tongue to retract, so as to achieve the purpose of unlocking.

The disadvantage of the aforementioned horn lock design is that Xiaoxiao often directly uses thin pieces to insert the door gap to force the lock tongue to retract, so that the purpose of unlocking can be achieved without the use of a key, and the security is relatively insufficient. Although the multi-stage lock can be used The multi-channel lock structure is designed to avoid prying open, but the structure is too complicated and the cost is high. In addition, users often only use the basic lock tongue buckle function in order to avoid the inconvenience of multi-channel opening procedures. It is easy to be picked open, and the security is relatively insufficient. However, the above-mentioned prior art can only use a single lock cylinder, and cannot arrange multiple lock cylinders to increase the difficulty of unlocking, but it is still easy to be cracked in a short time.

In addition, the "auxiliary lock" of Taiwan Patent No. M362275 mainly has a lock head, a lock bolt and a rotary knob assembly. The lock head is installed on the outer side of the door panel and has a transmission rod. The lock bolt is installed on the door panel The plate is provided with a lock tongue that can protrude from the end surface of the door panel. The rotary knob assembly is installed on the inner surface of the door panel and connected with the transmission rod that passes through the lock bolt. By turning the rotary knob assembly, the lock tongue can be controlled to unlock or lock. The action of locking, and this kind of lockset is comparatively complicated in structure equally, also can't be provided with a plurality of lock cylinders to increase the difficulty of unlocking, and the security of door lock is comparatively insufficient.
