Description

【Technical field】 [0001] The invention relates to the technical field of door lock equipment, in particular to a double lock cylinder lock head. 【Background technique】 [0002] The tumbler lock that family uses is usually made up of lock housing and two horizontally arranged lock cores at present, is connected with lock head shift fork by inner assembly between two lock cores. When the key is inserted into the keyhole, the key will push the upper pin just out of the pin hole of the lock cylinder, and at the same time push the inner component to the lock cylinder on the other side. At this time, the lock cylinder can be rotated by twisting the key, and at the same time, the inner assembly is driven, and then the inner assembly drives the lock fork to move the dead bolt to open the lock. Such action can be completed inside and outside the door, therefore, it is more convenient to use. [0003] However, most of the existing double lock core locks on the market have the proble...
