Disk and pull ring are installed in round bar both ends respectively, and rectangular deck is set on round bar shaft, and disk and side on round bar shaft
Compressed spring is set in region between shape deck.
Preferably, the pedestal that is tethered at is spherical cap structure, and is opened up on its convex surface side for being embedded in the quick-release
The card slot of connector, and open up at card slot the hole of mating bolt installation.
Preferably, the bolt assembly includes bolt and plate nut, and wherein bolt is tethered at pedestal direction described in
Through being tethered at pedestal, basin type inner cavity and the body connector three, and by be arranged on body connector
The mating installation of plate nut.
The beneficial effect that a kind of cargo hold provided by the present invention is tethered at structure is, both ensure that the hermetic properties of cargo hold,
The connection of mooring network or arresting net is facilitated again, with structure is simple, light-weight, good manufacturability, is readily produced and assembles, dismantles
The advantages that convenient, maintainable high, while there is versatility again；The present invention uses modularized design, and realization is tethered at pedestal, quick-release
The standardized designs of connector, remaining structure can be according to the specific structure slight changes of different aircrafts, that is, mountable.

Specific embodiment
To keep the purposes, technical schemes and advantages of the invention implemented clearer, below in conjunction in the embodiment of the present invention
Attached drawing, technical solution in the embodiment of the present invention is further described in more detail.In the accompanying drawings, identical from beginning to end or class
As label indicate same or similar element or element with the same or similar functions.Described embodiment is the present invention
A part of the embodiment, instead of all the embodiments.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to use
It is of the invention in explaining, and be not considered as limiting the invention.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Structure is tethered to cargo hold of the invention with reference to the accompanying drawing to be described in further details.
As shown in Figure 1, a kind of cargo hold is tethered at structure, including quick-release coupling 1, be tethered at pedestal 3, airtight bowl 4, Airtight gasket 5,
Body connector 7 and bolt assembly.Wherein, airtight bowl 4 is by annulus outer and the basin type being connected with the annulus outer internal diameter
Inner cavity composition, what in basin type inner cavity, concave side was provided with embedded quick-release coupling 1 is tethered at pedestal 3.The quick-release coupling 1 is selected by justifying
Bar, disk, pull ring, rectangular deck and compressed spring combine the form to be formed, specially round bar both ends install respectively disk and
Pull ring is set with rectangular deck on round bar shaft, and pressure is set in the region between the disk and rectangular deck on round bar shaft
Contracting spring, as shown in Figure 2.Pedestal 3 is tethered at then using spherical cap structure, and straight side fits on the concave surface of basin type inner cavity, and is
It keeps on file then to open up the card slot for being embedded in quick-release coupling 1 on 3 convex surface side of seat, and opens up the hole of mating bolt installation at card slot
