The invention discloses a lifting back-locking lock bar which comprises a bottom shell and a surface cover which are fixed through a screw rod, a spring bolt is arranged between the bottom shell and the surface cover, and a movable frame body is arranged in the bottom shell; two U-shaped supports are fixed to the bottom shell through screws and located in the movable frame body. A reset spring is arranged between the end, away from the spring bolt, of the movable frame and the inner wall of the bottom shell. A back locking block is arranged in the movable frame body, and the symmetrical edges of the back locking block can be located in the U-shaped support in a lifting mode. And an outer door handle structure and an inner door handle structure are arranged between the bottom shell and the surface cover. The outer door handle structure is reasonable in structural arrangement, the outer door handle structure rotates, the counter locking piece is lifted to achieve counter locking, operation is convenient and fast, the number of counter locking structures can be reduced, machining cost can be reduced, meanwhile, assembling cost can be reduced, assembling efficiency can be improved, using stability and reliability can be improved, and the outer door handle structure is high in applicability and good in practicability.
本发明公开了一种上提反锁锁利，包括通过螺杆固定的底壳和面盖，底壳与面盖之间设置有锁舌，底壳内设置有活动框体；底壳上通过螺钉固定有两个U形支架，两个U形支架处于活动框体内部；活动框体的远离锁舌一端与底壳内壁之间设置有复位弹簧；活动框体内设置有反锁块，反锁块的对称边沿可提升处于U形支架内；底壳和面盖之间设置有外门把手结构和内门把手结构。本发明的结构设置合理，外门把手结构转动并使反锁件上提实现反锁，其操作便捷，可以减少反锁结构的设置，有利于降低加工成本，同时也有利于降低装配成本，提高装配效率，并且也有利于提高使用平稳性和可靠性，适用性强且实用性好。
