referring to fig. 5, the base 100 is provided with a card slot 101 along the X direction; referring to fig. 6, a central portion of the card slot 101 forms a placement space of the card seat 201; referring to fig. 2, the base 100 is provided with a trapezoidal through hole 102 along the Y direction; one end of the trapezoidal through hole 102 is a large-diameter hole 1021, the other end of the trapezoidal through hole is a small-diameter hole 1022, and the small-diameter hole 1022 is communicated with the clamping groove 101; the buckle spring 203 is placed in the large-diameter hole 1021, one end of the buckle ejector rod 202 is located outside the large-diameter hole 1021, and the other end of the buckle ejector rod 202 penetrates through the small-diameter hole 1022 after penetrating through the buckle spring 203 and is finally fixed on the surface of the buckle seat body 201; the surface of the buckle seat body 201 is also fixedly provided with a buckle fixing rod 204, and the buckle fixing rod 204 is arranged in parallel with the buckle top rod 202.
The principle of use of the snap unit 200 is:
when the assembly of fixed plate and quick-release hinge structure on the aircraft cabin skeleton needs to be realized, the use mode is: when no external force is applied to the snap ejector 202, the snap seat 201 is located in the middle of the snap groove 101 under the action of the snap spring 203, so as to snap the snap groove 101, which is the state shown in fig. 6.
Then, in the state of fig. 6, the buckle rod 202 is pushed leftward, the buckle rod 202 overcomes the acting force of the buckle spring 203 to compress the buckle spring 203, so as to move the buckle base 201 leftward, and further move the buckle base 201 away from the slot 101, and meanwhile, when the buckle base 201 moves leftward, the buckle rod 204 fixed on the buckle base 201 is also driven to move leftward, and further the buckle rod 204 is moved away from the slot 101.
At the moment, the quick-release hinge structure is moved, the fixing plate on the aircraft cabin framework is inserted into the clamping groove 101, and at the moment, the through hole formed in the fixing plate has the same height as the buckle fixing rod 204; then, the leftward pushing force on the snap rod 202 is released, and under the action of the snap spring 203, on the one hand, the snap fixing rod 204 moves rightward and is inserted into the through hole formed in the fixing plate, so as to limit and fix the fixing plate. On the other hand, the buckle base 201 moves rightwards, so that the fixing plate is clamped, and the clamping effect on the fixing plate is realized. Therefore, the quick-release hinge structure and the fixing plate are connected and fixed.
When the quick-release hinge structure needs to be disassembled, the buckle base body 201 is separated from the clamping groove 101 only by pushing the buckle ejector rod 202 leftwards, and meanwhile, the buckle fixing rod 204 is separated from the through hole formed in the fixing plate, so that the quick-release hinge structure can be taken down. Therefore, the quick-release hinge structure has the advantages of convenience and quickness in mounting and dismounting.
