The utility model relates to a kind of overturning structure of heat exchanger tube plate polishing frock, overturning support, two positioning assemblies for positioning circular tube plate are arranged on the overturning support and present left-right symmetry distribution, the positioning assembly includes support component rotationally installed on overturning support.This overturning structure of heat exchanger tube plate polishing frock realizes the self-adaptive centering function of V-shaped clamping plate, ensures that the reference position of tube plate is consistent before and after turning over, avoids double-sided processing deviation, significantly improves the coaxiality and flatness of tube plate double-sided polishing, and the combination design of lifting component and elastic piece effectively disperses tube plate weight, avoids the edge deformation caused by excessive clamping force of tube plate, and when turning over is completed, electric push rod retracts, lifting frame is automatically reset under the action of elastic piece, reduces unnecessary operation process, further improves the efficiency of heat exchanger tube plate processing, and by adjusting the stroke of linear driver, different diameter tube plate can be adapted.

The utility model discloses an island cabinet is with the sealed formula mouth frame structure of preventing drooping, related island cabinet mechanical structure technical field, including mouth frame body and first screw hole, the mouth frame body's four corners are equipped with a plurality of first screw holes, the mouth frame body's four corners are equipped with the reinforced corner spare, the outer surface of reinforced corner spare is equipped with a plurality of second screw holes, the middle part of first screw hole and second screw hole is penetrated with screw, the one side welding of reinforced corner spare has upper support beam, lower support beam. The mouth frame body four corners L type reinforced corner spare of this island cabinet is with the sealed formula mouth frame structure of preventing drooping, and the body is fixed through screw, forms rigid corner part support, and the overall structure intensity is strengthened, and the edge corner deformation is inhibited and is drooping, and the upper support beam of the upper symmetry setting, lower support beam is connected through the hollow cylindrical support column of inside with cross -shaped reinforcing rib, constitutes the "G" type anti -deformation frame, effectively disperses the door body weight and mechanical stress, prevents the mouth frame from drooping further.

The utility model discloses a folding and unfolding structure of a multi-wheel-set landing gear for a model airplane. A landing wheel frame comprises a fixed frame rod and two groups of movable wheel frames, a plurality of landing wheel sets arranged in the length direction of the movable wheel frame are installed on the movable wheel frame. The movable wheel frames are arranged on the two sides of the fixed frame rod; the side end of the movable wheel frame is rotationally mounted at the side end of the fixed frame rod through a rotating shaft; the server is installed in the middle of the two movable wheel carriers, and a horizontally-arranged rotating cross rod is arranged at the lower end of the push rod. A group of rotating pull rods are respectively arranged between the rotating cross rod and the two groups of movable wheel carriers; two ends of the rotating pull rods are respectively hinged and matched with the rotating cross rod and the movable wheel carriers; in order to solve the problem that the folding and unfolding functions of an existing model airplane multi-wheel undercarriage set are difficult to achieve, reliable folding and unfolding of the multi-wheel undercarriage set are achieved through cooperative work of a large-tension server, a rotating transverse rod, a rotating pull rod and other structures, and the defects of a traditional servo control mode in application of the multi-wheel undercarriage are overcome.
