This utility model discloses a portable antenna base for microwave communication, including a support base. A second baffle is inserted into the inner wall of the first baffle, and a third baffle is inserted into the inner wall of the second baffle. A first locking knob is inserted into the upper edge of one side of the first and second baffles, and a second locking knob is inserted through the lower end of one side of the first baffle. This portable antenna base for microwave communication can be bolted on using a first fixing bolt, a mounting plate, and a mounting plate. Different shaped mounting plates can be fixed using the matrix screw holes of the mounting plate, resulting in better installation adaptability. It can be easily pushed and pulled using a push-pull handle and rollers, and can be stably supported and fixed using threaded sleeves and threaded rods, ensuring stable installation. The first, second, and third baffles can be flipped and unfolded to form a protective structure, and can be powered by a lithium battery.

This invention relates to the field of vehicle-mounted refrigeration equipment technology, specifically to a drawer slide structure, a vehicle-mounted refrigerator, and its assembly method. The drawer slide structure includes a slide rail and a drawer. The slide rail includes a sliding part and a fixed part, with the sliding part slidably connected to the fixed part. A drawer mounting plate is connected to the bottom of the drawer, and the mounting plate is fixedly connected to the sliding part of the slide rail. The fixed part is fixedly connected to a base, which is fixedly connected to the inner liner of the vehicle-mounted refrigerator. A drawer locking groove is connected to the bottom of the drawer. A locking connector is connected to the drawer mounting plate, and the connector engages with the locking groove. This invention creatively solves the problems of existing drawer slide structures, such as inconvenience in disassembly, limited load-bearing capacity, and poor operational stability, demonstrating significant progress and practical value.

This utility model belongs to the field of sliding door technology, and in particular to an anti-sway sliding door. The anti-sway sliding door includes a first sliding door, a second sliding door, and an upper track. The tops of the first and second sliding doors are respectively arranged in the upper track, and the bottoms of the first and second sliding doors are respectively provided with a first lower track and a second lower track. The first and second lower tracks are respectively provided with lower tracks for rolling along the ground. The first and second lower tracks are also respectively provided with a first side track and a second side track. A first anti-sway kit is provided between the first and second side tracks. When the first and second sliding doors are pushed and pulled left and right, the first anti-sway kit prevents the first and second sliding doors from swinging in opposite directions, making the sliding process more stable and providing a better user experience.
