Description

Technical Field

[0001] The utility model relates to the technical field of parts transportation, in particular to a crankshaft connecting rod parts blister tray. Background Art

[0002] The crankshaft connecting rod is an important component in the internal combustion engine. It connects the piston and the crankshaft, converting the reciprocating motion of the piston into the rotational motion of the crankshaft. This conversion process is an important part of the engine's internal energy conversion. After the crankshaft connecting rod is produced, the part needs to be transported to the assembly workshop for assembly.

[0003] At present, the existing crankshaft connecting rod parts are wrapped and transported by foam or air bag, which results in the consumption of more packaging materials. The packaging materials cannot be reused. At the same time, the crankshaft connecting rods are directly stacked and collide with each other during transportation. They cannot be fully fixed, resulting in chaotic stacking of parts and certain defects. Utility Model Content
