Abstract

The invention relates to the field of lock structures, and discloses a lock structure and a shielding door system. The lock structure comprises a mounting bottom plate, a first driving part, a sliding plate and two lock plates are arranged on the mounting bottom plate, the top end of the sliding plate is bent to form a bent part, an output shaft of the first driving part is connected with the bent part, a push plate is arranged at the bottom end of the sliding plate in the direction facing the mounting bottom plate in an extending mode and used for being connected with a second driving part, and a limiting column is arranged on the sliding plate; the lock plates are rotationally connected with the mounting bottom plate, the two lock plates are oppositely arranged, and lock grooves and hook grooves are formed in the lock plates. According to the lock structure, the sliding plates are arranged in a special structure mode, the mass of the sliding plates is reduced under the condition that the strength and the minimum deformation amount of the sliding plates are guaranteed, only when the two lock plates move to the first working position, the limiting columns can slide into the lock grooves, reliability is good, and under the unexpected condition, when the first driving piece cannot work, the sliding plates can slide into the lock grooves. And the sliding door can be opened through unlocking of the second driving piece, so that escape of passengers is ensured.

Description

technical field [0001] The invention relates to the field of lock structures, in particular to a lock structure and a screen door system. Background technique [0002] Rail transit has an increasing impact on people's daily life. The screen door system used in rail transit is a typical mechatronic product. The sliding doors of the screen door system are arranged at the edges of both sides of the rail transit platform to separate the vehicle running track from the platform, which not only ensures the safety of passengers, but also reduces the safety of passengers. The operating energy consumption of the ventilation system in the station reduces the noise impact on the platform when the train passes. Among them, the electromagnetic lock belongs to the transmission locking system of the rail transit screen door system. The main function is to assist the normal opening and locking of the sliding door to ensure the reliability of the sliding door opening and closing. In the sli...
