After the main lock tongue 26 pops up, when the cam 15 is rotated clockwise to the front limit by screwing the safety knob on the inner panel, the cam salient point 16 is clamped into the limit hole at the rear side of the upper cover plate 2 under the action of the cam salient point spring 36, at this time, the front limit foot of the cam 15 props against the front inclined plane of the clamping position of the V-shaped opening arranged at the left side surface on the lock tongue fixing plate 25, so that the main lock tongue 26 assembly props up, and at this time, the lock cannot be unlocked outdoors (namely, the reverse locking is realized).
The automatic mechanical lock solves the problem that a standard thumb wheel lock core cannot be used, is convenient for production and stock preparation of companies, and reduces fund backlog.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
