Abstract: A strong, durable, and more portable logistics box is capable of being assembled to form a three-dimensional box shape on rollers to store and transport items and being flattened for storage. The logistics box includes walls and locking devices including a first locking device and a second locking device. The walls include a bottom wall and a plurality of sidewalls. The sidewalls include a first sidewall, a last sidewall, and at least one middle sidewall rotatably connected between the first sidewall and the last sidewall. The first locking device is disposed between the first sidewall and the last sidewall and detachably connects the first sidewall to the last sidewall. The bottom wall is rotatably connected to one of the sidewalls. The second locking device is disposed between the bottom wall and another one of the sidewalls and detachably connects the bottom wall to the another one of the sidewalls.

Abstract: An adjustable partition structure includes a guiding member, two sets of support blocks, and an adjustable partition structure. The guiding member is fixed to a rear plate. The two sets of support blocks are respectively disposed on two side plates. Each set of support blocks includes a number of support blocks arranged in a longitudinal direction of the side plates. The adjustable partition structure includes a sliding member and an adjustable partition plate. The sliding member defines a sliding hole. The guiding member is received in the sliding hole. The sliding member is slidable relative to the rear plate along the guiding member. The adjustable partition plate and the sliding member are rotationally coupled together. Two side edges of the adjustable partition plate respectively form an abutting piece. The two abutting pieces are supported by the support blocks on a same plane to support the adjustable partition plate.

Abstract: A control device includes a housing and a button received within the housing. The housing defines a through hole and a latching slot. The button defines a pressing portion and a resilient arm. The pressing portion is slidably mounted within the through hole. One end of the resilient arm is coupled to the pressing portion, and a second end of the resilient arm is latched within the latching slot. When the pressing portion is pressed, the pressing portion slides to trigger a signal transmitting mechanism within the housing to emit a signal and causes the resilient arm to deform. When the pressing portion is released, the resilient arm is resiliently restored to cause the pressing portion to return to an initial position.

Abstract: A smart locker storage unit with compartments of adjustable size includes a housing and at least one detachable shelf assembly. The detachable shelf assembly in the housing interior space includes at least one shelf support, a detachable shelf, and at least one shelf lock. The shelf support is secured to the housing. The detachable shelf divides the housing interior space into a plurality of adjustably-sized compartments. The shelf lock is mounted on the shelf support. When the shelf lock is in a locked position, the shelf lock secures the detachable shelf on the shelf support. When the shelf lock is in an unlocked position, the shelf lock allows disengagement of the detachable shelf.
