Description

TECHNICAL FIELD

[0001] The utility model relates to cabin door support technical field more particularly to an airplane cabin door support protection structure. BACKGROUND

[0002] The airplane emergency cabin door is provided with a stop nut, and the cabin door frame is provided with a cabin door support corresponding to the stop nut. After the airplane emergency cabin door is closed, the stop nut can abut against the stop block of the cabin door support to limit the cabin door, so that the cabin door is prevented from moving in the horizontal direction away from the fuselage, and safety is ensured. During the airplane assembly stage, the airplane emergency cabin door needs to be opened and closed for many times to cooperate with the work of each station. If the cabin door mechanism is not adjusted in place, for example, the lock washer on the stop nut of the emergency cabin door is not installed in place, the stop nut is close to the stop block, and since the emergency cabin door is opened and closed by lifting (the structure of the emergency cabin door and how to open and close it by lifting are prior art), the stop block is prone to being knocked and thus damaged. In addition, if the operation method of the emergency cabin door is improper, the stop block will also be damaged

[0003] For example, patent application No. CN202420948033.8 discloses an airplane cabin door support protection structure and airplane cabin door assembly, which belong to the technical field of airplanes. The airplane cabin door support protection structure and airplane cabin door assembly of the utility model utilize the protective sleeve with a C-shaped structure to attach to the third end face of the stop block that is prone to being knocked, thereby avoiding the problem of damage to the stop block. At the same time, the side of the protective sleeve close to the first end face along the second direction is flush with the first end face. On the one hand, the edge formed by the first end face and the third end face can be protected by the protective sleeve to avoid the problem of damage to the edge. On the other hand, the protective sleeve does not interfere with the stop portion, thereby not affecting the normal closing of the emergency cabin door. The first limiting portion and the first end face abut against each other and / or the second limiting portion and the second end face abut against each other to fix the protective sleeve, thereby improving the installation stability of the airplane cabin door support protection structure, facilitating disassembly and assembly, and not causing pollution to the surface of the stop block.

[0004] After the airplane cabin door support protection structure and airplane cabin door assembly are improved, the protective sleeve is sleeved on the stop block of the support body to facilitate protection of the stop block. When the protective sleeve is installed on the outer wall of the stop block, two methods are adopted. One is to directly sleeve the protective sleeve on the outer wall of the stop block, but this method is not stable enough for the installation of the protective sleeve, and the protective sleeve is prone to falling off the outer wall of the stop block. The other method is to use the back glue to bond the inner wall of the protective sleeve to the outer wall of the stop block. However, when the protective sleeve needs to be replaced after a long period of use, it is not convenient to quickly remove the protective sleeve, and the outer wall of the stop block is prone to leaving residual glue, thereby affecting the firmness of the bonding between the protective sleeve and the stop block in the future. Therefore, improvement is needed. SUMMARY
