Household coded safe-guard chain door lock with chip key
The invention relates to a household coded safe-guard chain door lock with a chip key. The household coded safe-guard chain door lock comprises a front panel, a rear panel and a middle locking mechanism. An input terminal interface is formed in the front panel. A manual safety knob is arranged on the rear panel. Handle rotating shafts on the front panel and the rear panel are connected with a drive core of the middle locking mechanism. A motor box assembly is arranged in the middle locking mechanism, and provided with a clamping gear. The clamping gear is meshed with a driving gear of the middle locking mechanism. The driving gear drives a lock tongue of the middle locking mechanism to stretch out and draw back. The motor box assembly is controlled to be opened and closed through the input terminal interface in the front panel. According to the household coded safe-guard chain door lock, the situation that due to the fact that a key hole is blocked by a key billet or foreign matter, the key hole cannot be used can be fundamentally prevented. Meanwhile, the scruple of a user about surroundings in the door opening process can be eliminated. In an electronic door lock, due to the fact that a magnetic card has no code limit, a key card is likely to be copied. An induction type switch is transformed into a contact type switch, the price of a chip door lock is lowered, and the lock can be accepted by more people.
