[0029] EMBODIMENTS
[0030] As Figures 1-5 A plane suitcase top lifting mechanism, comprising a suitcase 10, a side face connecting assembly 20, a vertical connecting assembly 30 and a damping assembly 40.
[0031] The suitcase 10 comprises all the components necessary for a suitcase itself, and is itself prior art, so no further description is given.
[0032] The side face connecting assembly 20 serves as a strong support component for improving the stability of the suitcase 10 connected to the body.
[0033] The vertical connecting assembly 30 can improve the flexibility of movement of the suitcase 10 on the body.
[0034] The shock absorbing assembly 40 can reduce the shock suffered by the luggage case 10 when the flight state of the aircraft changes.
[0035] The side connecting assembly 20 includes a side plate support 21, a toothed plate one 22, a toothed plate two 23, and a plurality of connecting components, including commonly used connecting components such as bushings, screws, gaskets, nut seats, etc. Without special instructions, the connecting components can be used by those skilled in the art to complete common connections.
[0036] The side plate support 21 is fixed to the side wall of the luggage case 10 by screws, gaskets, and bushings. The toothed plate one 22 and the toothed plate two 23 are arranged on one side of the side plate support 21. The nut seat is fixed to the toothed plate two 23 by rivets. The side plate support 21 and the toothed plate one 22 are both provided with a slot hole, and a bushing is embedded in the slot hole. An open slot is formed in the bushing. By determining the position of the bushing in the slot hole and changing the axis position of the open slot, the screw can move in the open slot. The screw threaded through the toothed plate one 22 is connected with the nut buckle on the toothed plate two 23. The nut buckle is fixed to the nut seat by a clamp to stabilize and limit the position of the toothed plate one 22 and the toothed plate two 23 on the side of the side plate support 21. Because the axis length of the open slot in the bushing is greater than the diameter of the screw, the toothed plate two 23 can move up and down relative to the toothed plate one 22 to adjust the connection position relationship.
[0037] The contact surface of the toothed plate one 22 and the toothed plate two 23 is provided with teeth. The teeth on the toothed plate one 22 and the toothed plate two 23 are engaged with each other, which improves the convenience of installing the toothed plate one 22 and the toothed plate two 23 and improves the friction between the toothed plate one 22 and the toothed plate two 23.
[0038] If only the screw is used to fasten the toothed plate one 22 and the toothed plate two 23, there is a risk of loosening. However, the combination of the screw and the tooth engagement structure can firmly fix the toothed plate one 22 and the toothed plate two 23 to the luggage case side support, thereby improving the stability of the connection.
[0039] Preferably, the distance between the teeth is 0.6 mm.
[0040] Preferably, the direction of the teeth is perpendicular to the vertical direction.
[0041] In this embodiment, the side plate support 21 is first fixed to the side wall of the luggage case 10, and then the position relationship of the toothed plate one 22 and the toothed plate two 23 is determined. Finally, the toothed plate one 22 and the toothed plate two 23 are fixed to one side of the side plate support 21.
[0042] The vertical connecting assembly 30 comprises a pull rod 31, a connecting bracket 32, a sliding block 33 and a sliding rail 34. One end of the pull rod 31 is embedded with a universal shaft, a pin shaft penetrates through the universal shaft, the rear of the side plate bracket 21 and extends into the inner wall of the luggage case 10, and is limited by a latch; after the other end is aligned with the connecting bracket 32, another pin shaft penetrates through the pull rod 31 and the connecting bracket 32, and the pin shaft is limited by a corresponding latch. In this way, the two ends of the pull rod 31 are rotatably connected with the side plate bracket 21 and the connecting bracket 32 respectively, and the connecting bracket 32 is fixed by a nut, a gasket and the sliding block 33. When in use, the sliding block 33 can slide into the sliding rail 34 from the side to drive the entire luggage case 10 to slide on the sliding rail 34 to adjust the left and right positions. The sliding rail 34 is fixed to the body.
[0043] When installed, the gap positions of the two luggage cases 10 are taken, the side plate bracket 21 is fixed to the corresponding positions of the two adjacent luggage cases 10, a pin shaft penetrates through the side connecting assembly 20 on one side, the vertical connecting assembly 30 and the side connecting assembly 20 on the other side in sequence, and finally a latch is inserted to prevent falling off.
[0044] Further, the damping assembly 40 comprises a bushing 41, a damping rubber 42, a metal inner ring 43 and a rubber clamp 44. The damping rubber 42 is sleeved in the bushing 41, the metal inner ring 43 is sleeved in the damping rubber 42, and the rubber clamp 44 is buckled on the bushing 41 to prevent the damping rubber 42 from falling off. The metal inner ring 43 is sleeved on the pin shaft penetrating through the universal shaft.
[0045] When the aircraft is shaken during operation, no matter where the vibration comes from, the body vibration is transmitted to the damping assembly 40 through the vertical connecting assembly 30. The damping rubber 42 in the damping assembly 40 can play a damping role to reduce the amplitude of the vibration further transmitted to the luggage case 10, thereby achieving the damping purpose and improving the stability of the luggage case 10 placed in the body.
[0046] In summary, the benefits of the present application are:
[0047] 1. The tooth meshing structure in the side connecting assembly 20 increases the friction in the vertical direction. The tooth meshing structure in combination with the fixing effect of the screw can firmly fix the tooth plate one 22 and the tooth plate two 23 on the side plate bracket 21, thereby improving the stability of the connection between the luggage case 10 and the body.
[0048] 2. The tooth meshing structure of the tooth plate one 22 and the tooth plate two 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 fixed nut buckle on the tooth plate two 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 tolerance of the assembly.
[0051] 5. The shock absorbing assembly 40 reduces the probability of impact and abnormal sound when the luggage 10 is subjected to shock during flight.
[0052] The above merely describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the present application.
