Description

Heat insulation socket support structure

Technical Field

The utility model belongs to the technical field of aircraft structural design, concretely relates to thermal-insulated socket support structure.

Background

The traditional socket support structure for the aircraft mainly adopts integral forming, and the existing socket support structure is formed in an integral forming mode, so that the heat of the outer skin of the aircraft body can be conducted to a system socket through the heat conduction of the socket support, and the socket can be caused to break down due to overheating.

SUMMERY OF THE UTILITY MODEL

To the unable isolated heat-conducting problem of traditional socket bearing structure for the aircraft, the utility model provides a can realize that separation organism heat reaches thermal-insulated socket bearing structure to system's socket.

The above object of the present invention is achieved by the following technical solutions:

the utility model provides a thermal-insulated socket support structure, its characterized in that includes socket support, socket lid and thermal-insulated sealing washer, wherein has the recess clearance region between socket support and the socket lid amalgamation back, thermal-insulated sealing washer fill in socket support inner wall with in the recess clearance region, the terminal surface is pressed on thermal-insulated sealing washer's up end under the socket lid.

The socket support and the socket cover are both provided with lug pieces, and the socket support and the socket cover are connected with each other through detachable bolts through the lug pieces.

Because the socket support of the socket support structure for the aircraft is complex, the lug of the socket support is not easy to integrally form, so that the lug of the socket support and the socket support can be welded into a whole through welding, and argon arc welding is preferred for welding.

The utility model discloses a thermal-insulated socket support structure utilizes the regional design in groove gap after socket support and the assembly of socket cover, has guaranteed thermal-insulated sealing washer's packing, and the heat that can effectual separation organism covering reaches the system socket, avoids the overheated trouble of system socket.

Detailed Description

The heat insulation socket support structure of the present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic view of the thermal insulation socket support structure of the present invention. As shown, the insulated socket support structure includes a tab 1, a socket support 2, a socket cover 3, and an insulating gasket (not shown). In addition, the socket and the plug of each system are not shown in the figure

Fig. 2 is a schematic filling diagram of the heat insulating sealing ring of the heat insulating socket support structure of the present invention. As shown in fig. 2, a groove gap area exists between the socket support 2 and the socket cover 3 after being spliced, the heat insulation sealing ring 4 is filled in the inner wall of the socket support 2 and the groove gap area, and the lower end surface of the socket cover 3 is pressed on the upper end surface of the heat insulation sealing ring 4.

Socket support 2 and socket cover 3 all are provided with auricle 1, socket support 2 and socket cover 3 utilize through respective auricle 1 can dismantle bolt interconnect, and fig. 3 is the utility model discloses a thermal-insulated socket support structure's socket cover's installation schematic diagram, the thermal-insulated sealing washer 4 of not drawing in the figure. The socket cover 3 is detachable so that the heat insulating seal ring can be maintained and replaced, and the independent detachment and maintenance function of the system socket can be realized.

Since the socket base 2 of the socket base structure for the aircraft is complex, as shown in fig. 4, a plurality of protruding parts and edges exist, and the socket base is not easy to be integrally formed, the lug pieces 1 of the socket base 2 can be welded with the socket base 2 into a whole by welding, and argon arc welding is preferred. Since the receptacle cover 3 has a simple flat plate structure, the receptacle cover 3 and the tab 1 may be integrally formed.

The heat insulation sealing ring 4 can adopt a rubber pad with 300 ℃ high temperature resistance. The material of the socket holder 2 and the socket cover 3 may be an aluminum alloy or a titanium alloy, which can withstand higher temperatures.

The utility model discloses a thermal-insulated socket support structure's mounting means as follows:

four tabs 1 are welded integrally with a socket holder 2 by argon arc welding as shown in fig. 4, and then a heat insulating seal ring 4 is filled in a groove gap region between the socket holder 2 and a socket cover 3 and an inner wall of the socket holder 2 as shown in fig. 2. Finally, as shown in fig. 3, the socket cover 3 is connected to the socket holder 2 after the tab is welded by means of a detachable bolt.
