Description

Technical Field

[0001] This utility model relates to an eccentric adjustable foot mounting device for installation on an aircraft. Background Technology

[0002] Typically, multiple parallel sliding rails are installed in or on the floor of an aircraft cabin to flexibly and securely mount interior components such as seats, tables, cabinets, and partitions.

[0003] The aircraft slide rail features a groove extending along its length. The groove narrows and sits atop the slide rail. Several aligned notches are located on both sides of the groove, spaced at predetermined intervals, typically 1 inch apart. Interior trim components requiring connection to the slide rail have two or more feet at their bottom, each with raised edges. During installation, the raised edges of the feet are aligned vertically with the notches on the slide rail. The feet are then inserted into the groove, moved to offset the raised edges, and finally, the connecting screws are tightened to secure the interior trim components to the slide rail.

[0004] However, due to errors in the production of interior components and deformation during use, the position of the mounting feet may shift. This can make it difficult for the mounting feet to be properly engaged in the aircraft rails during installation, thus affecting the installation efficiency of the interior components.

[0029] Example:

[0030] like Figures 1 to 4 The eccentric adjustable foot mounting device shown in this embodiment is installed on an aircraft and includes a connecting block 9, a screw 2, a foot 8, a base 1, a fixing block 7, a small eccentric bushing 5, and a large eccentric bushing 6.

[0031] The base 1 is used to fix it in the mounting groove at the bottom of the interior trim component. In this embodiment, the base 1 has a horizontally penetrating operating space 1.1 in the middle, and a mounting opening 1.2 is provided in the middle of the lower part of the operating space 1.2. The mounting opening 1.2 penetrates the lower part of the base 1 vertically and horizontally. The side of the base 1 has an inlay groove 1.3 corresponding to the position of the mounting opening 1.2. The connecting block 9 has connecting ears 9.1 on both sides. The connecting block 9 is horizontally embedded in the mounting opening 1.2, and the connecting ears 9.1 are embedded in the inlay groove 1.3. The connecting ears 9.1 are fixedly connected to the base 1 by fixing bolts 4, so that the connecting block 9 can be detachably installed at the bottom of the base 1.

[0032] The larger eccentric bushing 6 is larger than the smaller eccentric bushing 5. Both the smaller eccentric bushing 5 and the larger eccentric bushing 6 are eccentric structures. Specifically, the center of the bushing hole 5.2 of the smaller eccentric bushing is offset from the center of the smaller eccentric bushing 5 itself, and the center of the bushing hole 6.2 of the larger eccentric bushing is offset from the center of the larger eccentric bushing 6 itself. The upper ends of both the smaller eccentric bushing 5 and the larger eccentric bushing 6 are equipped with adjusting heads. The adjusting heads are hexagonal in shape, allowing them to be rotated using conventional tools such as hex wrenches or sockets.

[0033] A vertical mounting hole 9.2 is provided in the middle of the connecting block 9. The diameter of the mounting hole 9.2 is equal to the outer diameter of the large eccentric bushing 6. The large eccentric bushing 6 fits into the mounting hole 9.2 and can rotate within it. The adjusting head 6.1 of the large eccentric bushing is located on top of the connecting block 9. The diameter of the sleeve hole 6.2 of the large eccentric bushing is equal to the outer diameter of the small eccentric bushing 5. The small eccentric bushing 5 fits into the sleeve hole 6.2 of the large eccentric bushing and can rotate within it. The adjusting head 5.1 of the small eccentric bushing is located on top of the large eccentric bushing 6. The screw 2 passes through the sleeve hole 5.2 of the small eccentric bushing. The external hexagonal thread head 2.1 of the screw is located on top of the small eccentric bushing 5, and the lower end of the screw 2 extends to the bottom of the connecting block 9.

[0034] The external hexagonal threaded head 2.1 of the screw, the adjusting head 5.1 of the small eccentric bushing, and the adjusting head 6.1 of the large eccentric bushing are all located in the operating space 1.1. External tools such as hexagonal wrenches or sockets can be easily inserted into the operating space 1.1 to adjust the screw 2, the small eccentric bushing 5, and the large eccentric bushing 6.

[0035] In this embodiment, the two sides of the foot 8 are respectively provided with protrusions 8.1, and the top center of the foot 8 is provided with a threaded hole 8.2. The foot 8 is threadedly connected to the lower end of the screw 2 through the threaded hole 8.2.

[0036] In this embodiment, the fixing block 7 is cylindrical with a through hole in the middle. The fixing block 7 is fitted onto the screw 2 and located between the foot 8 and the connecting block 9. Figure 4 As shown, the lower end of the fixing block 7 is provided with two downward protruding locking blocks 7.1. The two locking blocks 7.1 are located on both sides of the foot 8. The locking blocks 7.1 are used to engage with the notch 10.2 of the aircraft slide rail 10 during installation. When the locking blocks 7.1 are engaged with the notch 10.2 of the aircraft slide rail 10, the horizontal position of the foot 8 will be fixed, so that the foot 8 cannot slide.

[0037] In this embodiment, a washer 3 is also fitted on the upper end of the screw 2. The washer 3 is located between the external hexagonal thread head 2.1 of the screw and the adjusting head 5.1 of the small eccentric bushing.

[0038] The usage process of the eccentric adjustable foot mounting device in this embodiment is as follows:

[0039] The eccentric adjustable foot mounting device is fixedly installed on the bottom of the interior trim component via its fixing block 1. The foot 8 is located below the interior trim component. Usually, more than two eccentric adjustable foot mounting devices are installed on the bottom of the interior trim component to achieve stable fixation of the interior trim component.

[0040] When it is necessary to fix the interior parts to the aircraft slide rail 10, align the protrusion 8.1 of the foot 8 vertically with the notch 10.2 of the aircraft slide rail 10. At this time, as shown... Figure 5As shown, the foot 8 is then lowered into the groove 10.1 of the aircraft slide rail 10. During this process, if the position of the foot 8 shifts due to errors in the production of interior parts or deformation during use, causing changes in the distance between two or more foot 8s, making it difficult for the foot 8s to align and engage with the aircraft slide rail 10, external tools such as hex wrenches or sockets can be inserted into the operating space 1.1 to rotate and adjust the small eccentric bushing 5 and the large eccentric bushing 6. This will adjust the horizontal position of the foot 8, allowing two or more foot 8s to align with the aircraft slide rail 10 simultaneously and engage smoothly. After inserting the foot 8 into the groove 10.1 of the aircraft slide rail 10, slide it a certain distance along the groove 10.1 so that the protrusion 8.1 of the foot 8 is misaligned with the notch 10.2 of the aircraft slide rail 10, and the locking block 7.1 at the lower end of the fixing block 7 is vertically aligned with the notch 10.2 of the aircraft slide rail 10. Then, use an external hex wrench or socket wrench to rotate the screw 2 in the operating space, causing the foot 8 to rise. The locking block 7.1 at the lower end of the fixing block 7 then engages with the notch 10.2 of the aircraft slide rail 10. Finally, tighten the screw 2 to achieve fixation. Figure 6 As shown.

[0041] When it is necessary to remove interior trim components from the aircraft slide rail 10, use an external hex wrench or socket wrench to reach into the operating space and rotate the screw 2 in the opposite direction to loosen the screw 2. Then slide it along the aircraft slide rail 10 until the protrusion 8.1 of the foot 8 aligns with the notch 10.2 of the aircraft slide rail 10. After that, the interior trim component can be lifted upwards to achieve disassembly. During the disassembly process, if disassembly is difficult due to deformation, the position of the foot 8 can be adjusted by rotating and adjusting the small eccentric bushing 5 and the large eccentric bushing 6.

[0042] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
