Abstract

The invention discloses a mechanical lock for a safety door. The mechanical lock for the safety door comprises a front fixed plate. Fastening screw holes are formed in the front surface of the front fixed plate. The fastening bolt holes are connected with a rear fixed plate in the manner that bolts are inlaid into fastening hole sleeves. A door handle is arranged on the surface of the front fixedplate. The door handle is in transmission connection with a transmission rod through a handle connecting shaft. A finger type groove is formed in the outer surface of the door handle. A rotary shaft lantern ring is arranged at the position of connection between the front fixed plate and the handle connecting shaft. A key hole is formed in the front surface of the front fixed plate. A spring bolt is arranged on one side of the front fixed plate. A key sleeve is arranged on the inner surface of the rear fixed plate. The key sleeve is connected with a spring bolt through a spring bolt plate. Pressing gaskets are arranged at the corners of periphery of the outer surface of the rear fixed plate. A spring bolt hole is formed in one side of the rear fixed plate. According to the mechanical lock for the safety door, the mechanical lock is simple and reasonable in integrally structural design, relative simple in installation and detachment process, high in protection performance, and very highin flexibility and reliability.

Description

technical field [0001] The invention relates to the technical field of mechanical locks, in particular to a mechanical lock for a safety door. Background technique [0002] With the progress of the times, security doors are no longer limited to the use of ticket checking in airports, subways, etc., but are more used in high-end office buildings, libraries, theaters, factories, enterprises, exhibition centers, stadiums, tourist attractions, etc., to provide you with A fast, smooth and efficient two-way controllable passage is established, combined with a competitive and high-quality safe passage control system. Among them, the safety door as a fire exit is the most important. The safety door is generally equipped with a corresponding mechanical lock for the safety door. To the management role, it can play the necessary safety protection effect on the safety door when necessary. [0003] However, the mechanical lock of the existing safety door is more loaded down with trivial...
