Description
TECHNICAL FIELD
[0001] The utility model relates to a combined support. BACKGROUND
[0002] In the field of aircraft and the like, the heat and sound insulation layer is an important insulation system of the aircraft, mainly used for reducing the influence of noise and heat on the cabin environment, which is usually made of special materials and laid in the air-tight area of the whole aircraft fuselage, aiming to bear the stability of maintaining the cabin temperature and humidity, isolate the external engine noise and the aircraft noise, improve the comfort of passengers and crew members and ensure safety, etc. In addition, the EWIS (Electrical Wiring Interconnection System) is also an important part of the aircraft system, which refers to any wire, wiring device or combination thereof, including end point device, installed in any part of the aircraft for transmission of electrical energy (including data and signals) between two or more end points, which includes a variety of products such as wires or cables, connectors, protective materials, clamps, etc.
[0003] At present, when there is a demand for installing heat and sound insulation layer and EWIS wire harness in some specific areas of the aircraft at the same time, the heat and sound insulation layer and the EWIS wire harness are usually connected to the fuselage structure respectively by using installation structures (such as supports, nylon nails, etc.). For example, in the case of allowing hole opening in the metal fuselage wall plate, etc., the heat and sound insulation layer can be fixed on the fuselage bulkhead by using perforated nylon nails, gaskets, etc. In the case of not allowing hole opening in the composite fuselage wall plate, etc., such as shown in Figure 10 , the heat and sound insulation layer 77 can be fixed by using nylon snaps 73 to paste on the fuselage wall plate 71 and the longeron 72, or by using gaskets and adhesive nails 74 to clamp the heat and sound insulation layer on the longeron for further fixation. In addition, as shown in Figure 11 , the wire harness 78 such as EWIS is generally connected to the fuselage structure by using the support 79, and the main fixing methods include tie straps or clamps 76, etc.
[0004] However, although the above fixing and installation method is simple, the separate installation and fixation inevitably leads to the large size of the installation structure and the complexity of the installation components. INVENTION CONTENTS

The same or corresponding reference numerals in the drawings represent the same components, and repeated description is omitted.
[0038] In addition, unless explicitly specified and limited, the terms indicating the orientation or positional relationship are used only for the convenience of description, and are not limited to the structural orientation or positional relationship, etc. The terms "mounting", "connecting", and "connecting" should be understood broadly, and the terms "first", "second", and "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance. The specific meanings of the above terms in the present application can be understood by those skilled in the art according to the specific circumstances.
[0039] Reference Figures 1 to 9 An embodiment of the present application discloses a combination support P, comprising a mounting base 1, a spacer 2, a wire harness support 3, an adapter 4, and a fastener 5.
[0040] <Mounting base 1>
[0041] The mounting base 1 has a seat portion 11 and a rod body 12 protruding from the seat portion 11. In addition, a rod body side threaded portion 121 is provided at the protruding end of the rod body 12 away from the seat portion 11, and a protrusion portion 13 is formed on the outer surface of the rod body 12. The protrusion portion 13 is annular and is provided in multiple in the axial direction of the rod body 12.
[0042] Specifically, as shown in Figure 2 The mounting base 1 is formed in a substantially T shape when viewed from the side. The seat portion 11 is formed in a sheet shape. The rod body 12 protrudes in a manner perpendicular to the seat portion 11. The side of the seat portion 11 where the rod body 12 is not formed (i.e. the side opposite to the spacer 2 described below) can be used as an adhesive surface for pasting to the fuselage wall panel. The pasting surface can be formed in a planar shape, and a pasting material can also be provided thereon, thereby avoiding damage to the fuselage wall panel. Preferably, the rod body side threaded portion 121 is formed as a hole with threads inside at the protruding end of the rod body 12.
[0043] <spacer 2>
[0044] The spacer 2 is detachably fitted to the rod 12 so as to sandwich the plate-shaped member with the seat 11. Specifically, as shown in Figure 3 the spacer 2 is formed in an elastic sheet shape and formed with a hole portion 21. The hole portion 21 includes an opening 211 through which the rod 12 passes and a plurality of slits 212 extending radially from the opening 211 toward the outer side of the rod 12. When the spacer 2 is fitted to the rod 12 through the opening 211, the portions of the spacer 2 between the slits 212 are allowed to move along the rod 12 to a prescribed position due to temporary elastic deformation by an external force such as a pressing action of an operator. When there is no external force, the spacer 2 is caught between two adjacent protrusion portions 13 of the outer surface of the rod 12 due to elastic return, that is, the opening 211 is fixedly engaged with the protrusion portions 13. At this time, the spacer 2 and the seat 11 are formed in a structure that can sandwich the plate-shaped member.
[0045] Further, the spacer 2 is preferably formed in a circular sheet shape, and the opening 211 is preferably formed at the central portion of the spacer 2. In the present embodiment, the slits 212 radiate four pieces at 90° angles from the center of the spacer 2, that is, the center of the circle (the plurality of slits 212 are formed in a cross shape as a whole), but are not limited thereto, and for example, can radiate two pieces at 180° angles from the center of the circle (the plurality of slits 212 are formed in a linear shape as a whole), or two pieces at 120° angles from the center of the circle, or can be formed in a herringbone shape, and the like.
[0046] <wire harness support 3>
[0047] The wire harness support 3 is a bracket for fixing a wire harness and is detachably provided on the side of the rod 12 opposite to the spacer 2 and the seat 11, and includes a bracket main body 31 connected to the rod 12 and a passing portion 32 provided to the bracket main body 31 and through which the wire harness passes.
[0048] Further, as shown in Figure 4 , Figure 5 the passing portion 32 can be formed in a plurality of pieces and the bracket main body 31 is integrally formed. Specifically, the passing portion 32 is located at the end portion of the bracket main body 31 and extends in a manner that the end portions of the two portions branched from the bracket main body 31 are brought close to each other in a semicircular shape. However, the shape of the passing portion 32 is not limited thereto, and for example, can be formed in a structure such as a band or a strap, as long as the wire harness can be fixed.
[0049] Further, a connecting portion 311 is formed on the bracket body 31 to be connected to the rod body 12, and the connecting portion 311 includes, but is not limited to, a connecting method such as engagement, screwing, and the like. For example, an engaging portion can be provided on the protruding end of the rod body 12, and the connecting portion 311 of the bracket body 31 is formed to be engaged by the engaging portion. Further, for example, a screw thread (rod body side screw thread portion 121) can be provided on the surface of the protruding end of the rod body 12, and the connecting portion 311 is formed as a hole having a screw thread, so that the both are screw-connected. Further, for example, if the rod body side screw thread portion 121 is formed as a hole having a screw thread inside on the protruding end of the rod body 12, the connecting portion 311 can be formed as a through hole, and in this case, a fastener 5 is required for connecting the wire harness support 3 to the mounting base 1.
[0050] <fastener 5>
[0051] The fastener 5 is, for example, a bolt or a screw having a screw thread, and is capable of being screw-connected to the rod body side screw thread portion 121 of the mounting base 1. Specifically, the fastener 5 is screw-connected to the rod body side screw thread portion 121 of the mounting base 1 after passing through the connecting portion (through hole) 311 of the wire harness support 3.
[0052] (single layer combination structure)
[0053] Hereinafter, a case where only one wire harness support 3 is required will be described.
[0054] First, the mounting base 1 is fixed to a specific portion of the fuselage, such as a wall panel 71, a hat stringer 72, or the like, by using a back adhesive or an adhesive, or the like.
[0055] Next, a heat and sound insulation layer 77 as a plate-like member is laid on the specific portion, and the rod body 12 of the mounting base 1 is passed through a corresponding hole portion of the heat and sound insulation layer, and then the grommet 2 is fitted, so that the heat and sound insulation layer is sandwiched between the grommet 2 and the seat portion 11 of the mounting base 1, thereby fixing the heat and sound insulation layer.
[0056] Next, the wire harness support 3 is mounted to the protruding end of the rod body 12 of the mounting base 1 by the connecting portion 311 and is fixed, and then the wire harness 78 is passed through the passing portion 32.
[0057] However, when one wire harness support 3 is not sufficient to satisfy the wire harness fixation, two or more wire harness supports 3 are required to be mounted, and therefore an adapter 4 is required. Hereinafter, this will be described in detail.
[0058] <adapter 4>
[0059] The adapter 4 is rod-shaped and used to connect multiple wire harness support members 3. One end of the adapter 4 is detachably connected to the protruding end of the rod body 12, and the other end is detachably connected to the wire harness support member 3. The adapter 4 includes a first adapter-side threaded portion 41 and a second adapter-side threaded portion 42. The first adapter-side threaded portion 41 is formed at one end of the adapter 4 and engages with the rod body-side threaded portion 121. The second adapter-side threaded portion 42 is formed at the other end of the adapter 4. Preferably, the second adapter-side threaded portion 42 is formed to engage with the first adapter-side threaded portion 41, that is, two adapters 4 can be connected to each other via the first adapter-side threaded portion 41 and the second adapter-side threaded portion 42.
[0060] In addition, such as Figure 6 As shown, preferably, the second adapter-side threaded portion 42 has a larger diameter than the first adapter-side threaded portion 41, and the diameter of the connecting portion (through hole) 311 is between the diameter of the first adapter-side threaded portion 41 and the diameter of the second adapter-side threaded portion 42, so that the connecting portion 311 of the wire harness support 3 abuts against the second adapter-side threaded portion 42 after being penetrated by the first adapter-side threaded portion 41 of the adapter 4. Furthermore, preferably, the second adapter-side threaded portion 42 has a blind hole 421 at its protruding end away from the first adapter-side threaded portion 41, and a thread is formed inside the hole. Preferably, the threaded portion 121 on the rod side is formed into a hole with internal threads at the protruding end of the rod 12, and the blind hole 421 has the same hole diameter and matching thread as the threaded portion 121 on the rod side. Therefore, the threaded portion 41 on the first adapter side is naturally matched with the thread of the blind hole 421. Thus, the adapter 4 itself can be continuously screwed together (i.e., multiple adapters 4 can be screwed together end to end).
[0061] (Superimposed combination structure)
[0062] The following explains the situation where two or more wire harness support members 3 are required.
[0063] like Figure 1 , Figure 7 As shown, the first adapter-side threaded portion 41 of the adapter 4 passes through the connecting portion 311 of the wire harness support 3 closest to the mounting base 1 and is screwed into the rod-side threaded portion 121. At this time, the wire harness support 3 is clamped by the second adapter-side threaded portion 42 and the rod 12. Then, another wire harness support 3 is installed at the top of the second adapter-side threaded portion 42 and fixed with fasteners 5. At this time, the wire harness support 3 is clamped by the second adapter-side threaded portion 42 and fasteners 5.
[0064] Figure 8 and Figure 9 This paper illustrates a specific application example of the combined support structure of this application on a hat-shaped stringer 72.
[0065] Although not shown, since the adapter 4 can be continuously screwed, more wire harness support members 3 can be continuously stacked as described above to meet the installation requirements of more wire harnesses. Furthermore, the wire harnesses can be arranged in staggered arrangement and the like by adjusting the wire arrangement height. Moreover, since the wire harness support member 3 is a clamped structure, it can freely rotate around the shaft, so that the installation direction of the wire harness can be further freely adjusted.
[0066] In addition, in the present embodiment, the mounting base 1 can be formed as a rigid structure such as a metal member, but can also be formed as an elastic structure such as a rubber member, and is not particularly limited as long as the function is not affected. As the adhesive material between the mounting base 1 and the fuselage wall panel 71, a commonly used adhesive on the market can be selected as long as the required strength is met, and of course other known structures such as rivet fixation can also be used.
[0067] In summary, the combined support of the present application adds the function of wire harness installation to the traditional thermal and acoustic insulation layer installation structure through a simple structure, and can realize single wire harness and multi-wire harness installation of EWIS wire harnesses, and support installation requirements in different directions and at different heights, and the combined support after combination can also be flexibly disassembled according to requirements, greatly increasing the adaptability. Therefore, the combined support of the present application can meet the installation requirements of the thermal and acoustic insulation layer and the installation requirements of the wire harness, reduces the number of components, improves the space utilization efficiency, and has a wide application prospect.
