Abstract: A device for roasting beans which is significantly easier to install and place in a bean-roasting machine includes a chassis, a bean roasting tube, and a driving member. The chassis defines an accommodating cavity and a receiving hole communicating with the accommodating cavity. The bean roasting tube includes a rotating member and a chamber. The rotating member is detachably connected to the chassis. The chamber includes a first end plate, a second end plate opposite to the first end plate, and a bearing piece fixedly connected between the first end plate and the second end plate. The second end plate faces the receiving hole and is rotatably connected to the rotating member. The driving member is fixed to the first end plate and movable to drive the chamber to rotate in the accommodating cavity.

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 door pivot assembly used for secure storage includes a bushing, a nut and a bolt. The bushing is secured to a door frame, and the bushing has a non-threaded bore therethrough. The nut is secured to a door panel, and the nut has a threaded bore therethrough. The threaded bore of the nut aligns with the non-threaded bore of the bushing. The bolt passes through the door panel and the door frame. The bolt has a head, a threaded shaft, and a non-threaded shaft. The threaded shaft and the non-threaded shaft sequentially extend from the head. The threaded shaft is screwed into the threaded bore of the nut, and the non-threaded shaft is rotatably disposed in the non-threaded bore of the bushing, so that the door panel can be pivoted relative to the door frame. A smart locker having the door pivot assembly is also provided.

Abstract: A cabinet door mounting structure for detachably mounting a cabinet door to a cabinet body includes a mounting base, a mounting post, and a mounting plate. The mounting base defines a latching slot. The mounting post extends from the mounting base and is configured to rotationally couple the cabinet door to the cabinet body. The mounting plate is fixedly coupled to the cabinet door. The mounting plate is configured to be bent to latch the mounting plate in the latching slot to mount the cabinet door to the mounting base.
