<p>A preloading cathode lock utilizing a leveraged force transmission component, comprising a lock body (21); a lock catch (22) capable of rotating around a main shaft (211) fixed on the lock body (21); a gear assembly (23) under the action of the lock catch (22) on the inner side of the lock body (21) when the lock catch (22) on the outer side of the lock body (21) is pressed; a swing cam (24) capable of shifting between a stopposition preventing a clamping head (2322) located at one end of the gear assembly (23) from moving and a release position releasing the clamping head (2322); and an electric control driving assembly controlling the swing of the swing cam (24). The preloading cathode lock has high working efficacy and working efficiency, and satisfies the requirement of employing a smaller solenoid force to open a door when a lock is under a relatively large external force, thus reducing the phenomenon that the lock cannot be immediately unlocked due to the force borne by the lock catch when an external force is applied to the lock catch or when the door is deformed.</p> |
