The airport luggage scale includes a frame, a weighing scale, and a conveyor. The electronic weighing scale is installed on the frame, and the conveyor is located above the weighing scale. The conveyor is detachably connected to the frame. The conveyor is equipped with a first positioning part, and the frame is equipped with a first positioning fitting part. The frame is equipped with a self-locking device, and the self-locking device includes a limiting part. The limiting part is configured to limit the first positioning part after it is matched with the first positioning fitting part, so that the conveyor is fixedly installed on the frame. The luggage scale limit part includes a stopper, and one end of the stopper near the first positioning fitting part has a guiding slope. The first positioning part is configured to contact the guiding slope before the first positioning part is matched with the first positioning fitting part, so as to drive the stopper to move away from the first positioning fitting part. The aviation luggage scale conveyor is equipped with a second positioning part, which is located near the front end of the conveyor, and the first positioning part is located near the rear end of the conveyor. The frame is equipped with a second positioning fitting part, which is located lower than the first positioning fitting part. The conveyor can rotate relative to the second positioning fitting part to enable the first positioning part to cooperate with the first positioning fitting part.

One of the second positioning part and the second positioning matching part of the airport luggage scale is a pivot slot, and the other is a support rod, which can be limited within the pivot slot. The self-locking device also includes a guide sleeve, a guide rod, and an elastic member, with the guide sleeve installed on the inner side of the frame; The guide rod is inserted into the guide sleeve and connected to the limit part; The elastic component is set on the guide rod, with one end of the elastic component in contact with the limit part and the other end of the elastic component in contact with the guide sleeve. The self-locking device also includes a driving device, which is connected to the limiting part. The driving device can drive the limiting part to move away from the first positioning fitting part, or the driving device can drive the limiting part to move above the first positioning fitting part. The self-locking device also includes a connecting part; The driving device includes a reciprocating driving mechanism, which is installed on the outer side of the frame. The frame is equipped with a sliding track, and the connecting part is installed on the sliding track. One end of the connecting part is connected to the reciprocating driving mechanism, and the other end of the connecting part is connected to the limit part. The self-locking device also includes a driving device and a connecting part. The driving device includes a reciprocating driving mechanism, which is installed on the outer side of the frame. The frame is provided with a sliding track, and the connecting part is installed on the sliding track. One end of the connecting part is connected to the reciprocating driving mechanism. The part of the connecting part near the guide rod is provided with a through hole, and the guide rod passes through the through hole. The end of the guide rod away from the guide sleeve is provided with a limiting protrusion to stop the connecting part.

The reciprocating drive mechanism of the aviation luggage scale includes a screw assembly, which includes a screw nut and a screw rod. The screw nut is installed on the outer side of the frame, and the screw rod is connected to the screw nut thread. The screw rod is connected to one end of the connecting part, and can move back and forth along its own axis to drive the limit part to move. One of the first positioning part and the first positioning matching part of the airport luggage scale is a positioning slot, and the other is a positioning rod, which can be limited within the positioning slot. The luggage scale also includes a buffering device, which is connected to the frame and located between the conveyor and the weighing device. The luggage scale frame includes a crossbeam, which is located above the weighing scale; The buffer device includes a buffer rod and an elastic buffer component. The buffer rod is connected to the crossbeam in a movable manner. One end of the buffer rod is provided with a first limit protrusion, and the other end of the buffer rod is provided with a second limit protrusion, which can be in contact with the side of the crossbeam near the weighing scale. The elastic buffer component is sleeved on the buffer rod, and one end of the elastic buffer component is in contact with the first limit protrusion, while the other end of the elastic buffer component is in contact with the crossbeam.
