Description

Technical Field

[0001] This utility model belongs to the technical field of aircraft electrical circuit interconnection system, specifically relating to an equipment cabinet mounting rod for an amphibious aircraft. Background Technology

[0002] Aircraft equipment cabinets are primarily used for the fixed installation and electrical connection of airborne electronic equipment. They serve as integrated installation areas for various electronic devices on an aircraft and also incorporate design features such as waterproofing, ventilation, cooling, and shock absorption. The cabinet body is mostly a metal frame structure, with internal structural components primarily connected by bolts and rivets. The cabinet is fixed to the aircraft mainly through connections such as bottom structural beams to the aircraft structural support plates with nuts / bolts, bottom structural beams to the aircraft structural guide rails via anchor bolts, or connections between the top or side of the cabinet and the aircraft with tie rods.

[0003] To accommodate the installation and fixation of multiple electronic systems, aircraft equipment cabinets are typically large in size and heavy in weight. In addition, the assembly of the cabinet's structural components is quite complex. Therefore, there are significant errors in the assembly dimensions when assembling on board. The fixed-size structural installation requires a high level of assembly technology and is difficult to implement. Utility Model Content

[0004] This utility model provides a mounting rod for an equipment cabinet, which can solve the technical difficulties such as the assembly error of the equipment cabinet body and the high requirements for the on-machine assembly and installation process when the rod size is fixed, and reduces the assembly difficulty.

[0005] To address the existing technical problems, the present invention provides a mounting rod for an equipment cabinet of an amphibious aircraft, comprising an equipment cabinet support rod 101, a mounting base 102 between the rod cabinet and the rod structure, and a mounting base 103 between the rod structure and the equipment cabinet support rod 101. The equipment cabinet support rod 101 includes a support rod body 3, with internal threads at both ends. One end of the support rod body 3 is threadedly connected to a tension rod a2, and the other end is threadedly connected to a tension rod b4. The tension rod a2 is connected to the support rod end a1, and the tension rod b4 is connected to the support rod end b5. The support rod end a1 is connected to the mounting base between the rod structure and the equipment cabinet support rod 101. 103 is rotatably connected. The end b5 of the support rod is rotatably connected to the mounting base 102 between the pull rod cabinet and the equipment cabinet. The mounting base 102 between the pull rod cabinet and the equipment cabinet are connected. The mounting base 103 between the pull rod structure and the machine body structure are connected. By rotating the tension rod a2 and the tension rod b4, the extension and retraction of the tension rod a2 and the tension rod b4 can be adjusted to meet the connection distance requirements with the equipment cabinet and the machine body structure. By rotating the mounting base 102 between the pull rod cabinet and the mounting base 103 between the pull rod structure and the machine body structure, the connection angle requirements between the mounting base 102 between the pull rod cabinet and the equipment cabinet and the connection angle requirements between the mounting base 103 between the pull rod structure and the machine body structure can be met.

[0006] Furthermore, the equipment cabinet support rod 101 is a metal cylindrical structure.

[0007] Furthermore, tension rod a and tension rod b are respectively embedded in both ends of the equipment cabinet support rod 101 through internal threads. The extension length of tension rod a and tension rod b is adjusted according to the actual installation size requirements of the equipment cabinet. After the extension length of tension rod a and tension rod b is adjusted to the correct position, they are tightened with nuts.

[0008] Furthermore, the support rod end a1 and support rod end b5 have the same structure, both being fork-ear structures. One end of the fork-ear structure is connected to the corresponding tension rod, and the other end is provided with two symmetrical lugs. An opening is provided between the two lugs to cooperate with the mounting base 102 between the pull rod cabinet and the mounting base 103 between the pull rod structures. The mounting base 102 between the pull rod cabinet and the mounting base 103 between the pull rod structures are rotatably connected in the opening by a screw. When the angle of the mounting base 102 between the pull rod cabinet and the mounting base 103 between the pull rod structures meets the installation requirements, the mounting base 102 between the pull rod cabinet and the mounting base 103 between the pull rod structures are locked by the nut on the screw.

[0009] Furthermore, the mounting base 102 between the pull rod cabinets includes a mounting base body with four mounting holes a7 for connecting to the equipment cabinet. The mounting base body has a triangular lug with a top mounting hole a6. The triangular lug engages with the opening of the support rod end b5. A screw passes through the connecting hole on the lug of the support rod end b5 and the top mounting hole a6 on the lug, rotatably connecting the mounting base 102 between the pull rod cabinets and the support rod end b5. When the mounting angle of the mounting base 102 between the pull rod cabinets is rotated to the correct position, the nut on the screw locks the mounting base 102 between the pull rod cabinets, preventing the mounting base 102 between the pull rod cabinets and the support rod end b5 from rotating relative to each other.

[0010] Furthermore, the mounting base 103 between the tie rod structures includes a mounting base body. Two mounting holes b9 are provided on the side of the mounting base body for connection with the machine body structure. A round lug is provided at one end of the mounting base body, and a top mounting hole b8 is provided on the round lug. The round lug mates with the opening of the support rod end a1. By passing a screw through the connecting hole on the lug of the support rod end a1 and the top mounting hole b8 on the round lug, the mounting base 103 between the tie rod structures and the support rod end a1 are rotatably connected. When the mounting angle of the mounting base 103 between the tie rod structures is rotated to the correct position, the nut on the screw locks the mounting base 103 between the tie rod structures and the support rod end a1 so that the mounting base 103 between the tie rod structures and the support rod end a1 no longer rotate relative to each other.

[0011] Beneficial effects This utility model provides a mounting rod for an equipment cabinet on an amphibious aircraft, which has the following advantages: The mounting rod connects the equipment cabinet to the aircraft structure, ensuring reliable installation and fixation of the cabinet. Simultaneously, the extension length of the rod is adjustable by embedding tension rods at both ends of the support rod via internal threads. The installation angle is adjusted by rotating the axes of the mounting seats between the cabinet and the support rod, as well as the mounting holes between the mounting seats and the support rod. This reduces the dimensional tolerance requirements and installation difficulty during the assembly of the equipment cabinet on the aircraft. Attached Figure Description

The four mounting holes of the mounting base 102 between the equipment cabinet and the tie rod structure are fastened to the equipment cabinet with bolts. The two mounting holes of the mounting base 103 between the tie rod structure and the support rod are fastened to the machine structure with bolts.

[0016] The equipment cabinet support rod 101 serves as a connector between the equipment cabinet body and the frame web, achieving a fixed connection between the top and sides of the equipment cabinet body and the frame structure. The main body of the equipment cabinet support rod 101 is cylindrical, with tension rods embedded at both ends via internal threads. The extension length of the tension rods can be adjusted according to the actual installation dimensions. After the extension length of the tension rods is adjusted to the correct position, they are tightened with nuts.

[0017] The mounting base 102 between the pull rod cabinets has four mounting holes on its base that are securely connected to the equipment cabinet via bolts and nuts. The top hole is also secured to the equipment cabinet support rod via bolts and nuts, with a double-fastening mechanism using mechanical safety features. The mounting base can rotate around the axis of the mounting hole that mates with the equipment cabinet support rod to adjust the mounting angle.

[0018] The mounting base 103 between the tie rod structures has two holes at one end that are connected to the web of the machine frame via bolts and nuts for fastening, and a single hole at the other end that is reliably connected to the equipment cabinet support rod via bolts and nuts for fastening, with double fastening achieved through a mechanical safety mechanism. The mounting base between the tie rod structures can rotate around the axis of the mounting hole that mates with the equipment cabinet support rod to adjust the installation angle.

[0019] Specifically, the equipment cabinet support rod 101 includes an equipment cabinet support rod body 3. Both ends of the equipment cabinet support rod body 3 are provided with internal threads. One end of the equipment cabinet support rod body 3 is threadedly connected to the tension rod a2, and the other end is threadedly connected to the tension rod b4. The tension rod a2 is connected to the support rod end a1, and the tension rod b4 is connected to the support rod end b5. The support rod end a1 is rotatably connected to the mounting base 103 between the support rod structure and the support rod end b5 is rotatably connected to the mounting base 102 between the support rod cabinet and the pull rod. The cabinet mounting base 102 is connected to the equipment cabinet, and the rod structure mounting base 103 is connected to the machine body structure. By rotating the tension rods a2 and b4, the extension and retraction of the tension rods a2 and b4 can be adjusted to meet the connection distance requirements with the equipment cabinet and the machine body structure. By rotating the rod cabinet mounting base 102 and the rod structure mounting base 103, the connection angle requirements between the rod cabinet mounting base 102 and the equipment cabinet and between the rod structure mounting base 103 and the machine body structure can be met.

[0020] The equipment cabinet support rod 101 is a metal cylindrical structure. The two ends of the equipment cabinet support rod 101 are respectively embedded with tension rod a and tension rod b through internal threads. The extension length of tension rod a and tension rod b is adjusted according to the actual installation size requirements of the equipment cabinet. After the extension length of tension rod a and tension rod b is adjusted to the correct position, they are tightened with nuts.

[0021] Among them, the support rod end a1 and support rod end b5 have the same structure, both being a fork-ear structure. One end of the fork-ear structure is connected to the corresponding tension rod, and the other end is provided with two symmetrical lugs. An opening is provided between the two lugs to cooperate with the mounting base 102 between the pull rod cabinet and the mounting base 103 between the pull rod structure. The mounting base 102 between the pull rod cabinet and the mounting base 103 between the pull rod structure are rotatably connected in the opening by a screw. When the angle of the mounting base 102 between the pull rod cabinet and the mounting base 103 between the pull rod structure meets the installation requirements, the mounting base 102 between the pull rod cabinet and the mounting base 103 between the pull rod structure are locked by the nut on the screw.

[0022] The pull-rod cabinet mounting base 102 includes a mounting base body with four mounting holes a7 for connecting to the equipment cabinet. The mounting base body has triangular lugs with top mounting holes a6. The triangular lugs engage with the opening of the support rod end b5. A screw passes through the connecting hole on the lug of the support rod end b5 and the top mounting hole a6 on the lug, rotatably connecting the pull-rod cabinet mounting base 102 to the support rod end b5. Once the mounting angle of the pull-rod cabinet mounting base 102 is rotated to the correct position, the nut on the screw locks the pull-rod cabinet mounting base 102, preventing relative rotation between the pull-rod cabinet mounting base 102 and the support rod end b5.

[0023] The tie rod structure mounting base 103 includes a mounting base body with two mounting holes b9 on its side for connection to the machine body structure. One end of the mounting base body has a round lug with a top mounting hole b8. The round lug engages with the opening of the support rod end a1. A screw passes through the connecting hole on the lug of the support rod end a1 and the top mounting hole b8 on the round lug to rotatably connect the tie rod structure mounting base 103 to the support rod end a1. When the installation angle of the tie rod structure mounting base 103 is rotated to the correct position, the nut on the screw locks the tie rod structure mounting base 103, so that the tie rod structure mounting base 103 and the support rod end a1 no longer rotate relative to each other.

[0024] This invention connects the equipment cabinet to the aircraft structure via a mounting rod, ensuring reliable installation and fixation of the equipment cabinet. Simultaneously, the extension length of the support rod is adjusted by embedding tension rods at both ends using internal threads. The installation angle is adjusted by rotating the axes of the mounting seats between the equipment cabinet and the mounting holes between the support rod and the equipment cabinet, thus reducing the dimensional tolerance requirements and installation difficulty during onboard equipment cabinet assembly.
