Two-speed integrated hook lock and its locking method

Abstract

The invention relates to a two-gear integrated hook lock. The two-gear integrated hook lock comprises a lock box and a main transmission device in the lock box and is characterized in that hook lock devices are arranged in a lock panel at the lateral end of the lock box and are linked to the main transmission device; lock point shafts are arranged at the lateral end of a door frame horizontally, and open grooves are formed in the corresponding positions of the lock panel; when a door leaf and the door frame are closed, the lock point shafts are located in the corresponding open grooves and are connected to the hook lock devices in a clamped mode. The two-gear integrated hook lock automatically carries out two-gear locking when a door is closed, is convenient to open and is high in theft resistance and lock-picking resistance. A locking method adopts a brand new idea and is wide in application range.

Problems solved by technology

The existing anti-theft lock parts have a large number of transmissions, large volume, heavy weight, high cost, complicated structure, many wearing parts, and high mechanical failure rate due to improper operation.

Existing anti-theft doors only have one deadbolt that locks automatically when the door is closed indoors, but this deadbolt is in a free state, and can be opened with an accessory through the door gap outdoors.
