This invention belongs to the field of unmanned aerial vehicle (UAV) technology and discloses an aerial docking mechanism for UAVs, comprising: a docking mechanism including a docking rod, wherein a wedge-shaped groove is formed at the connection between the upper and lower parts of the docking rod; and a take-up and take-down mechanism including a take-up and take-down housing, spring torsion plates, a torsion spring, and a rotating assembly. There are two spring torsion plates, symmetrically and horizontally installed within the take-up and take-down housing, with a central groove formed between the two spring torsion plates. The two outer sidewalls of the two spring torsion plates at their closest points are connected to the inner sidewalls of the take-up and take-down housing via the torsion springs; the two outer sidewalls of the two spring torsion plates at their furthest points are rotatably connected to the take-up and take-down housing via the rotating assembly. This invention enables two UAVs to dock in mid-air, achieving docking through the wedge-shaped groove of the docking rod and the UAV with the docking rod installed can also overcome the force of the spring torsion plates to separate, thus solving the problem of UAV docking in mid-air.

The utility model discloses a gas film air-conditioned cold store heat preservation device which comprises a gas film wall, a heat preservation plate is fixedly arranged on the inner wall of the gas film wall, a rail is fixedly connected to the upper portion of the outer surface of the heat preservation plate, a supporting rod is movably inserted into the lower surface of the end of the rail in a penetrating mode, and a first turning plate is fixedly connected to the outer surface of the supporting rod. A second turning plate is hinged to the side edge of the first turning plate. The two groups of turning plates I and turning plates II are arranged to form two door plates, the rotating rod is rotated to pull the rack through the rope, so that the supporting rod is driven to rotate to turn over the turning plates I and open the door plates, the turning plates I and the turning plates II are in a parallel state when articles do not need to be taken, and the warehouse door is closed; the heat preservation effect of the refrigeration house is ensured.

The invention discloses a fabricated decorative building, which relates to the technical field of fabricated buildings, and comprises an external wall panel, an upper hook claw and a lower hook claw which are mounted at two ends of the inner side of the external wall panel, a support rod mounted in the upper hook claw and the lower hook claw, and a water guide cover mounted on the inner wall of the external wall panel. According to the external wall panel mounting structure, the external wall panels are arranged, the multiple external wall panels can form a decoration layer on the outer surface of a building, the upper hook claws and the lower hook claws are arranged at the two ends of the inner side walls of the external wall panels correspondingly, and the external wall panels can be fixed to the supporting rods in a hanging mode through the upper hook claws and the lower hook claws, so that rapid assembly and disassembly of the external wall panels are achieved; according to the external wall panel hanging device, the clamping jaw capable of being turned over is arranged at one end of the upper hook claw, the clamping jaw can be turned over and lock the position of the supporting rod after the upper hook claw is connected with the supporting rod so as to improve the stability of the external wall panel after being assembled, the clamping jaw drives the pressing block, the transmission arm and the transmission block through extrusion of the external wall panel, and automatic locking after the external wall panel is hung can be achieved.
