Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, an emergency oxygen module interface inspection tooling includes a tooling frame 3, an inspection panel 2, tooling feet 4, a first mounting bracket 1, a second mounting bracket 6, and positioning bolts 5; the middle part of the tooling frame 3 A sinking square emergency oxygen module inspection panel installation groove is provided. The inspection panel 2 is square as a whole, and three adjacent sides are fitted and fixed in the emergency oxygen module inspection panel installation groove, and the other side is connected to the There is a gap between the tooling frames 3, which is used to pass through the small door of the emergency oxygen module after opening; the first mounting bracket 1 and the second mounting bracket 6 are respectively symmetrically fixed on the upper surface of the tooling frame 3 corresponding to the inspection panel 2. Both sides of the two sides parallel to each other are fixed and installed; the positioning bolts 5 are installed horizontally on the first mounting bracket 1 and the second mounting bracket 6; the tooling feet 4 are fixedly installed on the tooling Four corner positions below the frame 3.
