Description

Technical Field

[0001] This invention relates to the field of aircraft packaging technology, and more particularly to a side-by-side connection structure for aircraft packaging boxes. Background Technology

[0002] Currently, aircraft packaging boxes are often transported by connecting two boxes in parallel to improve transportation efficiency. To ensure that the two side-by-side boxes do not tip over or fall due to transport inertial loads, a reliable and convenient method is needed to connect the two boxes.

[0003] Conventional side-by-side connection assemblies have high requirements for the height difference and spacing between the two packaging boxes. However, in actual operation, uneven surfaces (height difference greater than 5mm) are often encountered, making it impossible to install the side-by-side connection assemblies. Therefore, it is often necessary to level the two packaging boxes to the same horizontal height (height difference < 5mm) and hoist them to a fixed spacing. This introduces a significant amount of additional work into the packaging box shipping process. Summary of the Invention

[0004] The purpose of this invention is to provide a side-by-side connection structure suitable for aircraft packaging boxes.

[0005] To achieve the above objectives, the present invention provides a side-by-side connection structure for aircraft packaging boxes, comprising:

[0006] Two connectors are installed on the two aircraft packaging boxes respectively;

[0007] Two connectors are mounted on two connecting seats, each rotatably up and down. Each connector is provided with a stud section. The stud sections of the two connectors are spaced apart and opposite to each other. The two opposite stud sections are connected by a threaded sleeve. By rotating the threaded sleeve, the distance between the two opposite stud sections can be adjusted.

[0008] Optionally, the connector is an L-shaped post, including a stud section and a connecting section, wherein the stud section and the connecting section are arranged perpendicularly;

[0009] The connector is provided with a connecting hole, and the connecting section can be rotated up and down and inserted into the connecting hole.

[0010] Optionally, a stepped area is provided on the inner side of the connecting section. The surface of the stepped area is an arc surface, and the length of the stepped area is greater than the axial length of the connecting hole. When the threaded sleeve is locked with the two opposite stud sections, the arc surface of the stepped area matches the connecting hole.

[0011] Optionally, the arc surface of the step difference region is eccentric to the outer circumferential surface of the connecting segment, and the two have the same diameter.

[0012] Optionally, the step difference between the outer circumferential surface of the connecting section and the arc surface of the step zone is 3 to 5 mm.

[0013] Optionally, the threaded sleeve is provided with a gripping part.

[0014] Optionally, an anti-detachment part is provided between the gripping part and the connector. When the threaded sleeve is locked with the two opposite stud sections, the anti-detachment part restricts the rotation of the threaded sleeve relative to the connector.

[0015] Optionally, the anti-slip part can be a fixing strap or a felt buckle;

[0016] At least one of the connectors is provided with a fixing seat, and the fixing seat is provided with a fixing hole. When the screw sleeve is locked with the two opposite stud sections, one end of the fixing band or felt buckle is connected to the gripping part, and the other end passes through the fixing hole and is connected to the fixing seat to prevent the screw sleeve from rotating.

[0017] Optionally, the connector is a U-shaped post, including two stud sections and a connecting section, wherein the two stud sections are arranged in parallel and spaced apart, and the connecting section is arranged perpendicular to the stud section.

[0018] Alternatively, the threads of the two sleeves may be in opposite directions.

[0019] The above-mentioned technical solution of the present invention has the following advantages: The side-by-side connection structure for aircraft packaging boxes provided by the present invention includes two connecting seats and two connecting members. The two connecting seats are respectively installed on two aircraft packaging boxes, and the two connecting members are respectively rotatably connected to the two connecting member seats. Each connecting member is provided with a stud section, and the stud sections of the two connecting members are arranged opposite each other at a distance. The two opposite stud sections are connected by a threaded sleeve. By rotating the threaded sleeve, the distance between the two opposite stud sections can be adjusted. This side-by-side connection structure for aircraft packaging boxes can achieve a firm connection of two aircraft packaging boxes side by side. Furthermore, it has good adaptability, is easy to operate, and has a simple structure. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1

[0043] See Figures 1-4As shown, the side-by-side connection structure for aircraft packaging boxes provided in this embodiment of the invention includes two connecting seats 1 and two connecting members 2. The two connecting seats 1 are respectively installed on two aircraft packaging boxes, and the two connecting members 2 are rotatably connected to the two connecting seats 1 respectively. Specifically, each connecting seat 1 is rotatably connected to one connecting member 2, and the rotation of the connecting member 2 relative to the connecting seat 1 is in the up-down direction (here, the up-down direction refers to the top and bottom positions when the side-by-side connected aircraft packaging boxes are normally placed, see [reference]). Figure 5 ) rotation.

[0044] See Figure 2 and Figure 3 As shown, each connector 2 is provided with a stud section 21. The stud sections 21 of the two connectors 2 are arranged opposite each other at intervals. The two opposite stud sections 21 are connected by a screw sleeve 3. By rotating the screw sleeve 3, the distance between the two opposite stud sections 21 can be adjusted.

[0045] When using, please refer to Figure 5 As shown, two aircraft packaging boxes 6 to be connected are placed side by side. The stud sections 21 of the two connectors 2 are spaced apart and connected by screw sleeves 3. After the screw sleeves 3 are in place, the two aircraft packaging boxes 6 are firmly connected side by side. If the surfaces on which the two aircraft packaging boxes 6 are placed are uneven or there is a height difference due to machining accuracy errors, the two connectors 2 will adaptively flip up or down to achieve a firm connection between the two aircraft packaging boxes 6 side by side. This side-by-side connection structure for aircraft packaging boxes is adaptable, easy to operate, and simple in structure.

[0046] It should be noted that the number of side-by-side connection structures between the two aircraft packaging boxes 6 is determined based on the installation requirements and is not limited here. Multiple side-by-side connection structures can be individually height-adjusted to further improve adaptability.

[0047] In some implementations, see Figure 2 and Figure 3 As shown, connector 2 is an L-shaped post, including a stud section 21 and a connecting section 22, which are arranged perpendicularly. Those skilled in the art should understand that "perpendicular arrangement" here means that the axes of the stud section 21 and the connecting section 22 are perpendicular or approximately perpendicular, thus forming an L-shaped structure. In some integrally molded connection schemes, a transition angle due to bending may be formed at the connection between the stud section 21 and the connecting section 22; this situation still falls under the category of the stud section 21 and the connecting section 22 being perpendicularly arranged.

[0048] The connector 1 has a connecting hole 11, and the connecting segment 22 is rotatably inserted into the connecting hole 11. This embodiment does not impose excessive limitations on the structure of the connector, as long as it meets the requirements for installing the connector 2 and connecting with the aircraft packaging box 6. In a preferred embodiment, the connector 1 includes a connecting plate with multiple through holes for screws to pass through. The connecting plate is attached to the mounting surface of the aircraft packaging box 6, and the connector 1 is fixed to the aircraft packaging box 6 by screws. A protrusion is provided on the side of the connecting plate facing away from the aircraft packaging box 6, and the connecting hole 11 is provided on the protrusion for the connecting segment 22 to pass through.

[0049] Regarding the fit between the connecting segment 22 and the connecting hole 11, in some embodiments, see [link to relevant documentation]. Figure 2 and Figure 3 As shown, the inner side of the connecting section 22 is provided with a step area 221. The surface of the step area 221 is an arc surface. The length of the step area 221 is greater than the axial length of the connecting hole 11. When the threaded sleeve 3 is locked with the two opposite stud sections 21, the arc surface of the step area 221 cooperates with the connecting hole 11 to lock and fix the connecting piece 2.

[0050] To improve the fit between the stepped area 221 and the connecting hole 11, preferably, the arc surface of the stepped area 221 is eccentric to the outer circumferential surface of the connecting segment 22, and both have the same diameter. More preferably, the step difference between the outer circumferential surface of the connecting segment 22 and the arc surface of the stepped area 221 is 3-5 mm, for example, 3 mm, 3.6 mm, 4 mm, 4.5 mm, 5 mm, etc.

[0051] In some embodiments, to simplify the structure and reduce weight, the connecting seat 1 serves as a common mounting base for the connecting member 2 and the lifting ring (not shown in the figure), see [reference]. Figure 4 As shown, the connecting seat 1 has two connecting holes 11 spaced vertically. The connecting hole 11 located at the top is used to install the hoisting hole for hoisting the flight packaging box.

[0052] To facilitate the rotation of the threaded sleeve, in some embodiments, see [reference needed]. Figures 1-5 As shown, the threaded sleeve 3 is provided with a gripping part 4. In some specific embodiments, the gripping part 4 can be any structure that is convenient for the operator to grip, such as a gripping post structure, a handle, a protrusion, etc. In some preferred embodiments, the gripping part 4 is a rotating wheel, which is fixed on the threaded sleeve 3 and is very easy to operate.

[0053] To prevent relative rotation between the threaded sleeve 3 and the connecting member 2 during transportation, in some embodiments, see [reference needed]. Figures 1-5As shown, an anti-detachment part 5 is provided between the gripping part 4 and the connecting member 2. When the threaded sleeve 3 is locked with the two opposing stud sections 21, the anti-detachment part 5 restricts the rotation of the threaded sleeve 3 relative to the connecting member 2. In some specific embodiments, the anti-detachment part 5 can be a pin, passing through the insertion holes of both the threaded sleeve and the connecting member to prevent relative rotation between the two. In some preferred embodiments, the anti-detachment part 5 is a fixing strap or felt buckle. After the threaded sleeve is locked in place, one end of the fixing strap or felt buckle is fixed to the gripping part, and the other end is fixed to at least one of the connecting members 2 to prevent relative rotation between the two. In one embodiment, see [link to embodiment]. Figure 2 As shown, one of the connectors 2 is provided with a fixing seat 23, and the fixing seat 23 is provided with a fixing hole 231. When the screw sleeve 3 is locked with the two opposite screw segments 21, one end of the fixing strap or felt buckle is connected to the grip part 4, and the other end passes through the fixing hole 231 and is connected to the fixing seat 23 to prevent the screw sleeve 3 from rotating.

[0054] Example 2

[0055] See Figure 6 and Figure 7 As shown, this second embodiment is basically the same as the first embodiment, and the similarities will not be repeated. The difference is that the connector 2 is a U-shaped post, including two stud sections 21 and a connecting section 22. The two stud sections 21 are arranged in parallel and spaced apart, and are perpendicular to the connecting section 22. During connection, the two threaded sections 21 of the connector 2 are connected to the two stud sections 21 of the other connector 2 by a screw sleeve 3, thereby locking the two connectors 2 together. This results in a stronger connection, and the separate connection at both points provides a certain degree of protection against detachment during transportation.

[0056] To further enhance the anti-loosening function, in some embodiments, the threads of the two threaded sleeves 3 are in opposite directions.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that not every embodiment contains only one independent technical solution, and in the absence of conflict between solutions, the various technical features mentioned in each embodiment can be combined in any way to form other implementation methods that can be understood by those skilled in the art.

[0058] Furthermore, without departing from the scope of the present invention, modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some of the technical features, shall not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
