Description

Protective lock toggle device

The present invention relates to a lock structure, in particular to a strengthening of the lock's toggle mechanism so that it has better positioning, protection and stability functions.

According to the current situation, more sophisticated locks are installed for important access control in homes or offices to meet the needs of safe entry and exit. The structure of a conventional lock is shown in Figure 1, which shows a lock 90 provided on the door panel. The lock 90 includes a connected lock base 91 and a lock end plate 92. The lock base 91 is provided with a toggle base. Plate 911. The lock end plate 92 is provided with a locking hole 921, and a locking block 94 is movable at the locking hole 921; the lock end plate 92 is also provided with an inner insertion hole 924 and an outer insertion hole 923. 924 is inserted with an inner latch 926 for positioning an inner lock 99, and the end of the inner lock 99 is provided with a rotating plate 991; the outer jack 923 is inserted with an outer latch 925 for positioning an outer lock. The outer lock head 98 is provided with a key hole 981 for inserting a key for unlocking. A toggle member 93 is pivotally mounted on the toggle base plate 911. The toggle member 93 is provided with a keyhole 931. The keyhole 931 corresponds to the outer lock head 98 (keyhole 981).
