Technical Field

[0001] The present application relates to the field of aviation airborne product installation technology, and in particular to a quick-install and quick-disinstall structure for aircraft interior panels. Background Art

[0002] Aircraft interior panels, as the name suggests, are panels used to decorate the interior of an aircraft, thereby increasing the aesthetic performance of the aircraft interior. They are all made of special materials and have good physical properties. During the design process of aircraft interiors, it is necessary to consider both the quick installation and removal functions of the interior panels and the aesthetics of the interior. Traditional interior panels are usually fixed with ordinary screws, and operators fix the interior panels to the inside of the fuselage with screws.

[0003] With respect to the above-mentioned related technologies, the inventors believe that when using screws to install interior panels, the nail heads will inevitably be exposed during the installation of screws and other fasteners, and the edges of the interior trim are prone to uneven seams and step differences, and the installation is cumbersome and inconvenient for operators to operate. Summary of the invention

[0007] By adopting the above technical solution, by extending the two ends of the interior panel into the interior of the plug-in gap, and then shielding the edge position of the interior panel with the profile, and fixing the interior panel with the clamping structure, it is convenient for the installer to install and fix the interior panel inside the body.

[0008] Optionally, one end of the second plate body facing away from the interior panel is fixedly connected to a connecting plate, the bottom end of the second plate body facing away from the connecting plate is fixedly connected to a first clamping plate, the bottom end of the connecting plate close to one end of the second plate body is fixedly connected to a second clamping plate, and a decorative cover is clamped between the first clamping plate and the second clamping plate.

[0009] By adopting the above technical solution, by fixing one end of the decorative cover to the first clamping plate and the other end of the decorative cover to the second clamping plate, it is convenient to fix the decorative cover, and the surface of the profile is shielded by the decorative cover, thereby improving the aesthetics of the overall installed structure.

[0010] Optionally, the second plate body includes a fixed portion close to one side of the first plate body and a sliding portion located below the fixed portion, the fixed portion and the sliding portion being slidably connected therebetween, and the first clamping plate is fixed on the sliding portion, the decorative cover is an elastic member, and when the decorative cover is clamped between the first clamping plate and the second clamping plate, the decorative cover is in a compressed state, the sliding portion is fixedly connected with a first elastic member, an end of the first elastic member facing away from the sliding portion is fixedly connected with a card block, the fixed portion is provided with an avoidance hole relative to the position of the card block, and the interior trim panel is provided with a card slot relative to the position of the card block, when the card block is located at one end of the avoidance hole close to the connecting plate, the card block and the card slot are staggered, and when the card block is located at one end of the avoidance hole facing away from the connecting plate, the card block and the card slot are opposite and the card block can extend into the interior of the card slot.

[0011] By adopting the above technical solution, after the decorative cover is installed between the first clamping plate and the second clamping plate, since the decorative cover is in a compressed state, the decorative cover pushes the sliding part to slide toward the side away from the connecting plate, driving the clamping block to move inside the avoidance hole toward the side away from the connecting plate, and then the clamping block and the clamping slot are relative to each other, and the clamping block is pushed into the inside of the clamping slot by the first elastic member, so as to facilitate the fixation of the interior panel, and when the interior panel needs to be removed and replaced, it is only necessary to remove the decorative cover from between the first clamping plate and the second clamping plate, and the first elastic member drives the clamping block to disengage inside the clamping slot, thereby sliding the interior panel and the second plate body relative to each other and disengaging them.

[0012] Optionally, when the blocking block is located at one end of the avoidance hole close to the connecting plate, the distance between the two opposite first plates is smaller than the distance between the two opposite second plates; and when the interior panel is fully extended into one of the plug-in gaps, the interior panel abuts against the first plate at the other end and disengages from the second plate, and when the blocking block is located at one end of the avoidance hole away from the connecting plate, the distance between the two opposite first plates is the same as the distance between the two opposite second plates.

[0016] Optionally, a spring sheet is inserted into the first plate body, the spring sheet includes an inserting portion, the inserting portion is inserted into the first plate body, and a clamping portion is fixedly connected to the bottom end of the inserting portion, and the clamping portion extends into the inserting gap.

[0017] By adopting the above technical solution, the plug-in part is plugged and fixed on the first plate body, and then the clamping part extends into the inside of the plug-in gap, and the interior panel is clamped and fixed by the clamping part, thereby reducing the up and down movement of the interior panel and limiting the position of the interior panel.

[0018] Optionally, a pressing groove is provided on the upper surface of the interior trim panel at a position relative to the pressing portion, and the pressing portion can extend into the pressing groove.

[0019] By adopting the above technical solution, the clamping part can be extended into the clamping groove through the opening, thereby limiting the position of the interior panel, and when the clamping part extends into the clamping groove, it means that the interior panel is moved into place, which facilitates the card block to extend into the card slot.

[0020] Optionally, weight-reducing holes are provided on surfaces of the first plate body and the second plate body.

[0021] By adopting the above technical solution, the mass of the profile can be reduced by opening the weight-reducing holes, thereby reducing the counterweight of the overall installation structure and reducing the impact on the machine body.
