Description

Technical Field

[0001] The utility model relates to the technical field of cargo hold protection, in particular to an aircraft cargo hold lining. Background Art

[0002] Aircraft cargo hold linings are an important component of the interior of the aircraft cargo hold. They are mainly used to protect cargo, enhance the strength of the cargo hold structure, and provide fire and waterproof functions. The cargo hold linings will protect the structure inside the aircraft cargo hold to prevent damage to it during transportation. Strong linings can help ensure that the cargo remains stable during flight and reduce the risk of damage caused by cargo movement. Liners help maintain the cargo hold environment and prevent moisture and chemicals from penetrating into the aircraft structure. Many lining materials have fireproof properties and can slow down the fire in the event of a fire, buying time for emergency treatment. During the installation process of the aircraft cargo hold linings, the aircraft cargo hold linings are installed on the inner wall of the aircraft cargo hold by bolts, providing a certain degree of protection and protection for the inner wall of the aircraft cargo hold and the cargo subsequently loaded into the aircraft cargo hold. Since certain vibration forces will be generated during the aircraft flight operation and cargo loading, it is necessary to perform stable connection operations on the aircraft cargo hold linings.

[0003] In the related art, during the use of aircraft cargo hold linings, protective strips are generally adhered to the surfaces of the aircraft cargo hold lining connections to protect and stabilize the bolts connecting the aircraft cargo hold linings so that they can be used.

[0004] However, during the current use of aircraft cargo hold linings, due to the method of sticking protective strips, as the loosening of the bolts and the friction between the protrusions and the cargo inside the aircraft cargo hold, the protective strips will be damaged, and the bolt protrusions will be damaged faster, resulting in loose connections of the aircraft cargo hold lining bolts, causing the protective performance of the aircraft cargo hold lining protrusions to decrease, affecting the installation connection stability and protectiveness of the aircraft cargo hold lining.
