This utility model relates to the field of equipment support technology, specifically to an assembly bracket for an external sensor unit of a UAV. The assembly bracket includes a unit assembly frame with a connecting groove. A first locking crossbeam is slidably connected to the inner side of the connecting groove, and one end of the first locking crossbeam is fixedly connected to a lateral limiting post. A lower housing is embedded inside the first locking crossbeam and applies a pushing force to a sliding filler block originally located inside the first locking crossbeam, causing the sliding filler block to insert into a recessed locking seat. At this time, the self-locking switch is not subjected to the squeezing force of the lower housing, thus turning on the sensor power in the assembled state, which can be used to indicate that the stable installation has been completed. Simultaneously, because the first locking crossbeam is constrained by fixing bolts and the filling of the sliding filler block and the recessed locking seat on both sides, the overall installation gap is reduced, which can reduce vibration and ensure the stability of the externally mounted unit during flight.

This invention provides a food processing machine, including a main unit and a mixing cup detachably mounted on the main unit. The mixing cup contains a pulverizing blade. The main unit has a motor assembly for driving the pulverizing blade to rotate. The main unit includes a main unit housing, which forms a mounting cavity for mounting the motor assembly. The main unit housing has an opening communicating with the mounting cavity. At least a portion of the motor assembly forms the outer surface of the main unit together with the main unit housing through the opening, thereby reducing the size of the main unit, especially its height, making assembly simple and easy to handle.

This invention relates to the field of engine turbocharger technology and provides a turbine end sealing structure, including an intermediate shell on which a turbine shaft and a turbine housing are mounted; a turbine is mounted on the turbine shaft; a nozzle ring is mounted on the turbine housing; a turbine housing insert is installed inside the turbine housing; and a sealing plate is mounted on the nozzle ring, which mates with the turbine housing insert. The sealing plate is embedded in the nozzle ring to reduce the installation gap between the nozzle ring and the turbine housing, and to reduce the gap between the nozzle ring and the turbine housing insert, thereby ensuring that engine exhaust gas does not easily leak from the turbine end of the turbocharger.

This utility model discloses a locking linkage mechanism for a civil defense door in the field of security inspection technology. It includes a left civil defense door panel, a right civil defense door panel, and a housing.
