The invention relates to a subway door central lock mechanism which comprises an installation bottom plate fixed to a door body. An electromagnetic unlocking assembly, a pressure reset locking assembly and a rotary lock hook assembly are fixedly installed on the installation bottom plate. The rotary lock hook assembly comprises a hook, a rotary shaft and a bearing pedestal. The electromagnetic unlocking assembly comprises an electromagnet and a first fixed base. The electromagnet is provided with a telescopic connection rod. The pressure reset locking assembly comprises a damper and a second fixed base. The damper comprises a telescopic supporting rod. The free end of the telescopic supporting rod is hinged to the middle or the lower portion of a support rod. When the electromagnet is powered on, the telescopic connection rod pulls the support rod and drives the rotary shaft to rotate, then, the hook is rotated and uplifted to be unlocked, and the telescopic supporting rod can push the rotary shaft to rotate after the electromagnet is powered off so as to reset and lock the hook. The subway door central lock mechanism has the advantages that a traditional spring lock structure is changed, collision of all components will not occur basically in the unlocking and locking process, and therefore the damage rate of the components is greatly reduced; and the structure is relatively simple, the number of the components is relatively small, and the fault frequency is relatively low.
Description
technical field [0001] The invention belongs to the field of subway door locks, and in particular relates to a central lock mechanism for subway doors. Background technique [0002] With the rapid development of my country's subway industry, locomotives have put forward higher requirements for the reliability, maintainability and safety of the door system. The traditional central locking system of the door system has safety hazards in the use process due to the locking method of the central lock, and the structure of the locking device is complicated and there are many vulnerable parts. Therefore, in order to improve the safety of subway, need to develop a kind of novel subway door central locking mechanism, the mode of its locking should be different from the safer and more efficient other mode of bumping lock mode. Contents of the invention [0003] The present invention provides a central lock mechanism for subway doors, aiming to overcome the deficiencies in the prior...
