Label declaration:
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in more detail.
Embodiment 1
The utility model provides a kind of high security anti-error lock, as shown in Figure 3, comprises the compositions such as lock body 1, latch hook 2, deadlock lever 3, trip lever 4, pellet 5, identity code 6; Described latch hook 2 is arranged on above lock body 1; Described deadlock lever 3, trip lever 4, identity code 6 are arranged in lock body 1, wherein, deadlock lever 3 locking latch hook 2, trip lever 4 controls the movement of deadlock lever 3, and deadlock lever 3 rear end is provided with spring 7, and lock shaft 2 lower end is provided with spring 9; Be provided with concealed pellet 5 bottom described trip lever 4, pellet 5 lower end is provided with spring 8.
As Fig. 5, be lock body substructure schematic diagram, a step surface 11 is arranged at bottom, step surface 11 has multiple blind round hole 12;
