Rapid disassembly and assembly structure of airplane passenger service assembly

Abstract

The invention discloses a quick disassembly and assembly structure of an airplane passenger service assembly. A plurality of hanging holes are arranged in a guide rod in a length direction; and in aninstallation area of the passenger service assembly, the two guide rods are oppositely arranged, the guide rods are fixed to internal components of an airplane, at least two hooks are arranged on oneset of opposite sides of the passenger service assembly respectively, and the hooks on the two sides are buckled with the hanging holes in the corresponding sides respectively so that the passenger service assembly and the internal components of the airplane are fixed in a suspended mode. In the invention, rapid disassembly and assembly between the passenger service assembly and the airplane structure can be realized; and during installation, a small amount of thrust is applied to push the passenger service assembly upwards so that a lock catch on each hook is buckled into a suspension hole ineach guide rod, during disassembly, the lock catch on the hook is turned over towards an airplane structure by means of a tool, meanwhile, the passenger service assembly is jacked upwards, the lock catch is separated from the suspension hole, and then the passenger service assembly can be taken down. The structure is small and light, dismounting is convenient and fast, a requirement for an operation space is greatly lowered, and operation difficulty is greatly reduced.

Description

technical field [0001] The invention relates to a dismounting structure for component installation. Background technique [0002] Compared with the overall structure of the aircraft, the PSU (passenger service unit, passenger service unit) of an aircraft is relatively light in weight, and as a component that can directly contact with personnel, it needs to consider the requirements of humanization and easy disassembly and replacement. The installation mostly adopts the connection method of bolts and nuts with brackets to connect and fix the PSU panel and aircraft interior parts, etc. The disadvantages of this connection are: [0003] 1. The connection method of bolts and nuts with brackets greatly increases the weight of the overall aircraft, which in turn brings huge costs and fuel consumption; [0004] 2. Bolts and nuts need to be manually twisted during the installation process, which requires installation space and is restricted. Many sharp corner spaces and narrow posi...
