The invention belongs to the technical field of door locks, and particularly relates to a door opening and closing mechanism which comprises a locking part and an unlocking part, the locking part comprises a frame, a rotatable spring bolt and a limiting piece are arranged in the frame, a limiting spring is arranged between the limiting piece and the inner wall of the frame, and the limiting spring enables the limiting piece to have the trend of abutting against the end, located in the frame, of the spring bolt; a torsional spring is connected between the spring bolt and the limiting piece, a lock block and a push block which can sequentially extend out of the frame along with rotation of the spring bolt are formed on the spring bolt, a notch is limited between the lock block and the push block, an unlocking hole penetrating through the lock block is formed in the lock block, an unlocking push rod capable of pushing the limiting piece is arranged in the unlocking hole, and the unlocking push rod is sleeved with a reset spring. The reset spring enables the unlocking push rod to tend to be away from the limiting piece. Compared with a traditional door lock, the door opening mechanism has the advantages that the structure required for opening and closing the door is optimized, the door opening mechanism is easier to mount and use, and meanwhile, the production cost is reduced.
本发明属于门锁技术领域，特指一种开关门机构，包括闭锁部与解锁部，闭锁部包括框架，框架内设有可转动的锁舌与限位件，限位件与框架内壁之间设有限位弹簧，限位弹簧使得限位件具有抵住锁舌上位于框架内一端的趋势，锁舌与限位件之间连接有扭簧，锁舌上形成有可随其转动依次伸出框架的锁块与推块，锁块与推块之间限定有缺口，锁块内形成有将其贯穿的解锁孔，解锁孔内设有可推动限位件的解锁推杆，解锁推杆上套有复位弹簧，复位弹簧使得解锁推杆具有远离限位件的趋势。该开门机构相对传统门锁对开关门所需要的结构进行了优化，更易于安装与使用，同时还降低了生产成本。
