Abstract

The present invention provides an auto locked lock cylinder transmission structure after destruction, comprising a body which includes two lock cylinders. The two lock cylinders each include a driving block, which sets a penetrated driver axially, and the lock cylinders are respectively provided with an elastic component, which are respectively axially and elastically pressed against the driver, so that the driver is pressed against the direction of the cam. The lateral edge of the said driver is configured to a caging component. The cam is installed with a general passage which corresponds to the driver, so that the driver can drive to the cam. The radial wall surface of the general passage is installed with a limit unit corresponding to the limit component, and the said limit component and the corresponding limit unit are elastically connected while they are in alignment with each other. By means of it, different drivers are directly or indirectly against each other in the general passage and the limit unit are not aligned with the caging component at an initial position. And when one of the said driver is not elastically pressed by the corresponding elastic component, it will be elastically pressed by the said elastic component of the other driver to be pushed away from the general passage, and the other said limiting unit of the driver is assembled to the corresponding limiting units. As a result, the end of the lock cylinder and driving block after destruction can only be idly rotated but turn the cam to unlock and thus achieve the result of burglar-proofing while another end of the lock cylinder can still unlock by transmission to the cam with its driver, which prevents the body of the lock being locked because of another end of the lock cylinder being destroyed.

Description

However, its automatic locking setting is limited to a single side. If one side of the first clutch member is damaged, the automatic locking mechanism will lose its function, so that intruders can still pass through it. Therefore, the lock can only It is suitable for the indoor and outdoor doors of general compartments; and in some occasions, due to safety, it is necessary to install lock cores on both sides of the door body to unlock through the key, and to prevent intruders from breaking the locks on both sides and passing through, then Conventional locks cannot be used because of the automatic locking mechanism on one side, resulting in insufficient safety.
