Description

Technical Field

[0001] The present invention relates to the field of aircraft luggage case structures, and more particularly to a top hanging mechanism for an aircraft luggage case. Background Art

[0002] The load capacity of luggage boxes on civil aircraft needs to be designed to be larger. They need to withstand the relevant loads of flight conditions, ground conditions and emergency landing conditions at the same time. Therefore, the connection between the luggage box and the fuselage structure must be firm.

[0003] The existing connection method is not very stable, mainly because bolt connections are easily affected by fastening failure and abnormal tightening. During multiple tightening processes, the thread groove of the bolt is easily worn, resulting in loose connections. In addition, the stability of bolt connections is also affected by factors such as material quality, design rationality, and manufacturing process. The sheet metal itself is relatively thin, and the traditional connection method is prone to damage to the connection parts, affecting the overall stability. Summary of the invention

[0029] Example

[0030] like Figure 1-Figure 5 A top hanging mechanism for an aircraft luggage box includes a luggage box 10, a side connection assembly 20, a vertical connection assembly 30 and a shock absorbing assembly 40.

[0031] The suitcase 10 includes all necessary parts of a suitcase, and is prior art, so it will not be described in detail.

[0032] The side connection assembly 20 is used as a strong supporting component to improve the stability of the luggage case 10 connected to the body.

[0033] The vertical connection assembly 30 can improve the mobility of the luggage case 10 on the body.

[0034] The shock absorbing assembly 40 can reduce the vibration of the luggage box 10 when the flight state of the aircraft changes.

[0035] The side connection assembly 20 includes a side plate bracket 21, a tooth plate 1 22, a tooth plate 23, and a plurality of connection components. The connection components include common connection components such as bushings, screws, washers, nut seats, etc. Due to the versatility of the connection components, unless otherwise specified, technicians in this field can use the connection components to complete common connections.

[0036] The side panel bracket 21 is fixed to the side wall of the luggage box 10 by screws, washers and bushings. The tooth plate 1 22 and the tooth plate 23 are both arranged on one side of the side panel bracket 21; the nut base is fixed to the tooth plate 23 by rivets. The side panel bracket 21 and the tooth plate 1 22 are both provided with slots, in which bushings are embedded, and an open slot is provided in the bushing. By determining the position of the bushing in the slot and changing the axial position of the open slot, the screw can move in the open slot. The screw in the open slot passes through the tooth plate 1 22 and is connected to the nut buckle on the tooth plate 23. The nut buckle is fixed to the nut base by a clamp to stably limit the position of the tooth plate 1 22 and the tooth plate 23 to the side of the side panel bracket 21. Because the axial length of the open slot in the bushing is greater than the screw diameter, the tooth plate 23 can move up and down relative to the tooth plate 1 22 to adjust the connection position relationship.

[0037] Among them, teeth are provided on the contact surfaces of tooth plate 1 22 and tooth plate 2 23, and the teeth on tooth plate 1 22 and the teeth on tooth plate 2 23 are meshed with each other, which on the one hand improves the convenience of installing tooth plate 1 22 and tooth plate 2 23, and on the other hand plays a role in increasing the friction between tooth plate 1 22 and tooth plate 2 23.

[0038] If the tooth plate 1 22 and the tooth plate 2 23 are fastened only by screws, there is a risk of loosening. However, the inner tooth plate 1 22 and the tooth plate 2 23 can be firmly fixed to the side bracket of the luggage box by means of a tooth meshing structure in combination with screws, thereby improving the stability of the connection.

[0039] Preferably, the tooth spacing is 0.6 mm.

[0040] Preferably, the direction of the teeth is arranged perpendicular to the vertical direction.

[0041] In this embodiment, the side panel bracket 21 is first fixed to the side wall of the luggage box 10, and then the positional relationship between the tooth plate 1 22 and the tooth plate 2 23 is determined, and then the tooth plate 1 22 and the tooth plate 2 23 are fixed to one side of the side panel bracket 21 together.

[0042] The vertical connection assembly 30 includes a pull rod 31, a connecting bracket 32, a slider 33 and a slide rail 34. A universal shaft is embedded in one end of the pull rod 31. The pin passes through the universal shaft and the side plate bracket 21 and then extends into the inner wall of the suitcase 10, and is limited by a latch. After the other end is aligned with the connecting bracket 32, another pin is taken to pass through the pull rod 31 and the connecting bracket 32, and the corresponding latch is used to limit the pin. In this way, the two ends of the pull rod 31 are respectively connected to the side plate bracket 21 and the connecting bracket 32 ​​for rotation, and the connecting bracket 32 ​​is fixed by a nut, a gasket and a slider 33. When in use, the slider 33 can slide into the slide rail 34 from the side, driving the entire suitcase 10 to slide on the slide rail 34 to adjust the left and right positions. The slide rail 34 is fixed to the body.

[0043] During installation, take the gap position between the two suitcases 10, fix the side panel bracket 21 to the corresponding position of the two adjacent suitcases 10, use the pin to pass through the side connection component 20 on one side, the vertical connection component 30, and the side connection component 20 on the other side in sequence, and finally insert the pin to prevent it from falling off.

[0044] Furthermore, the shock absorbing assembly 40 includes a bushing 41, a shock absorbing rubber 42, a metal inner ring 43 and a rubber clamp 44. The shock absorbing rubber 42 is sleeved inside the bushing 41, the metal inner ring 43 is sleeved inside the shock absorbing rubber 42, and the rubber clamp 44 is buckled on the bushing 41 to prevent the shock absorbing rubber 42 from falling off. The metal inner ring 43 is sleeved on the pin shaft that passes through the universal shaft.

[0045] When the aircraft is vibrated during operation, no matter where the vibration comes from, when the vibration of the aircraft body is transmitted to the shock absorbing assembly 40 through the vertical connection assembly 30, the shock absorbing rubber 42 in the shock absorbing assembly 40 can play a shock absorbing role, reducing the amplitude of the vibration further transmitted to the luggage box 10, thereby achieving the purpose of shock absorption and improving the stability of the luggage box 10 placed in the aircraft body.

[0046] In summary, the benefits of this application are:

[0047] 1. The tooth meshing structure in the side connection assembly 20 increases the friction in the vertical direction. The tooth meshing structure and the fixing effect of the screws can firmly fix the tooth plate 1 22 and the tooth plate 2 23 on the side plate bracket 21 to improve the stability of the connection between the suitcase 10 and the body.

[0048] 2. The meshing structure between the teeth of the tooth plate 1 22 and the tooth plate 2 23 also facilitates the adjustment of the positional relationship between the two in the vertical direction during installation, and the adjustment accuracy is high.

[0049] 3. The fixing nut buckle on the tooth plate 23 can be quickly disassembled, which is convenient for disassembly and replacement.

[0050] 4. The pull rod 31 is provided with a universal shaft assembly, which increases the assembly margin of the assembly.

[0051] 5. The shock-absorbing assembly 40 can reduce the probability of collision and abnormal noise when the luggage case 10 is vibrated during flight.
