Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of engine packaging, in particular to a heavy vehicle engine packaging box. BACKGROUND

[0002] Heavy vehicle engine, also known as heavy duty engine or heavy load engine, is an important term in mechanical engineering, which specifically refers to engines that provide power for heavy vehicles. According to the type and purpose of the vehicle, there are various types of heavy vehicle engines, including but not limited to diesel engines, gasoline engines and alternative fuel engines. Heavy vehicle engine is the core component that provides power for heavy vehicles, which are usually used for transporting heavy objects or working in complex and harsh environments. Heavy vehicle engines usually adopt modular design for easy maintenance and replacement of parts. In order to protect the engine from damage, facilitate transportation and storage, and improve logistics efficiency, a packaging box is needed during the transportation of heavy vehicle engines.

[0003] The traditional heavy vehicle engine packaging box first cleans the surface of the box body and the top cover, then places the heavy vehicle engine inside the box body, and then connects the top cover with the box body, and seals the box body and the top cover with adhesive tape. During transportation, only the adhesive tape is used for sealing, which is easy to loosen and fall off, exposing the engine to the air, which not only leads to poor connection stability, but also causes damage to the engine. To solve the above problems, some heavy vehicle engine packaging boxes connect the top cover with the box body, and then connect them at the connection between the top cover and the box body with bolts, which not only improves the connection stability, but also ensures the safety of the engine. However, this method only uses bolts to connect the packaging box, which not only increases the difficulty of disassembly and assembly, but also is prone to loosening. Therefore, a heavy vehicle engine packaging box is proposed. SUMMARY
