Problems solved by technology
The radial seal is not easy to disassemble and assemble, and in the case of repeated disassembly and assembly, the sealing material is worn and the water resistance becomes poor. Once the seal fails, it cannot be repaired, and the sealant needs to be refilled

Embodiment Construction
[0025] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:
[0026] Attach the radome 1 (see figure 2 ) is designed as a composite structure composed of the mouth frame 6 and the cover body 7 . The mouth frame 6 is made of aluminum alloy, and the cover body 7 is made of glass fiber cloth. The mouth frame 6 and the cover body 7 are bonded with epoxy resin. A multi-stage waterproof edge is formed between the 7, and the bonding strength between the mouth frame 6 and the cover body 7 is increased at the same time.
[0027] Frame 6 in the radome port (see figure 2 ) is designed with an annular boss E on the inner side of the radome, and an O-ring 3 installation groove G is designed on the end face F of the radome annular boss, and the O-ring 3 is pasted in the installation groove G. At the same time in the cabin end frame 2 (see image 3 ) An annular boss K is designed inside the port, and the end surface N of the annular...

The invention relates to a seal structure for sleeve connection of a pod body and an antenna housing of an onboard electronic pod. The seal structure comprises an onboard electronic pod antenna housing and an onboard electronic pod body end frame and is characterized in that an opening frame is arranged at the opening end of the housing body of the onboard electronic pod antenna housing, an annular groove is formed in the outer side of the embedding section where the opening frame is connected with the housing body, and the annular groove is bonded to the housing body through epoxy resin. An annular boss is arranged on the inner side of the opening frame, an installation groove is formed in the end face of the annular boss, and an O-shaped sealing ring is bonded to the inside of the installation groove. An annular boss is arranged on the inner side of a port of the onboard electronic pod body end frame, and the end face of the annular boss and the outer end face of the pod body end frame are coplanar. The pod body end frame is sleeved in the opening frame, and the end face of the annular boss and the annular boss end face of the pod body end frame are bonded by means of screw fastening. The seal structure for sleeve connection of the pod body and the antenna housing of the onboard electronic pod can be applied to the fields of military and civil products which are free of flange connection in appearance, can only be in sleeve connection and are good in sealing and waterproof effects.
Description
technical field [0001] The invention belongs to the two technical fields of machinery and protection, and specifically relates to a sealing structure for the socket connection between the airborne electronic pod cabin and the radome. The solution is that it is inconvenient to install sealing material on the surface or apply sealant outside the seam, which is not convenient for product maintenance. It can be applied to military and civilian product fields that do not allow flange connections but can only be socketed and must be sealed and waterproof. Background technique [0002] In order to maintain the electronic equipment in the pod, the airborne electronic pod body and the radome adopt a split structure. The structure and shape of the outer surface of the pod affects the aerodynamic performance of the aircraft. In order to ensure that the aircraft has good aerodynamic stability and controllability, the airborne electronic pod cabin and the radome are connected by socket c...
