Abstract:
The present application relates to the technical field of storage devices, and discloses a door lock assembly, comprising a driving push rod, a spring bolt, a fixed push rod, and a positioning apparatus or a vacuum apparatus. The driving push rod is connected to a handle by means of a connecting rod assembly, and the driving push rod is provided with a sliding slot. The spring bolt comprises a first abutting surface that is capable of abutting against the driving push rod, and a second abutting surface that is arranged corresponding to the first abutting surface. The fixed push rod comprises a first insertion portion inserted into the driving push rod, and a first abutting portion that is capable of abutting against the second abutting surface of the spring bolt. The positioning apparatus comprises a first elastic element for pushing the fixed push rod. When the door lock assembly is in a locking state, the spring bolt abuts against the fixed push rod, and the handle may drive the driving push rod by means of the connecting rod assembly to move and squeeze the first abutting surface of the spring bolt, so that the spring bolt moves and is separated from the fixed push rod. Meanwhile, the positioning apparatus pushes the fixed push rod, so that the door lock assembly is in an unlocked state. The present application also discloses a box device.
