Bolt 5 is supported by gripper shoe 6, described bolt can bolt 5 in box-like housing 3 for open lock retrieving position and for close locking 1 extended position between flatly move.

Latch 4 can in box-like housing 3 for open lock retrieving position and for close locking extended position between flatly move.

In order to mobile latch 4, have the action bars 11 for promoting latch 4, it is pivoted to box-like housing 3 in 12; Also there is the mechanism for motion to be delivered to catch bar 11 from key.

Being positioned at, the top of gripper shoe 6 is one group of lockplate or barriers 7, and each in this group lockplate all can the mode of vertical translation move, and has the window 8 with tooth, and described tooth defines the passage recess 9 corresponding with the password of the key locking 1.

Each lockplate 7 includes stretching out and regaining the first vertical slots 14 and the second vertical slots 15 that direction is departed from bolt 5.

In the first vertical slots 14, first drives pivot 16 be engaged and be fixed on box-like housing 3, and in the second vertical slots 15, second drives pivot 17 engaged and be also fixed on box-like housing 3.

Especially, the driving pivot 16 and 17 together with linked up by the groove 14 of all lockplates 7 and 15 respectively (string) is cylinder respectively, and the cover plate of described cylindrical axis and box-like housing 3 is oriented orthogonally to.

Locking piece 10 or mortise lock (Mentonnet) are fixed on the gripper shoe 6 of bolt 5 and are positioned at window 8 inside.

The key of lock 1 is suitable for by making the tooth of window 8 unanimously activate lockplate 7, to open the passage that locking piece 10 can slide wherein.

The above-mentioned safety lock substantially belonging to general lockplate type.

There is shown other CONSTRUCTED SPECIFICATION of lock, because they are well known, thus describe no longer herein.

Replacing representation is carried out by burglary-resisting system in most important, the most novel aspect of lock 1, this burglary-resisting system comprises mobile device, when lockplate is subject to the barrier force along the withdrawal direction of bolt 5, this mobile device can make at least one and lockplates all especially in lockplate automatically move towards maximum raised position.

More particularly, when lockplate is in the raised position close to maximum raised position, this mobile device works to mobile lockplate 7.
