Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

A titanium alloy pressure-resistant cabin, which particularly refers to figures 1, 2, 3 and 4. Have cabin body 1, cabin stem 2 and cabin seat 3, the cabin body 1, cabin stem 2 and cabin seat 3 all adopt titanium alloy material to make, cabin body 1 is the bowl form structure, cabin stem 2 sets up in the 1 lower extreme of the cabin body, and with the 1 seamless connection of the cabin body, cabin stem 2 is step form cylinder structure, and it includes first cylinder 21, second cylinder 22 and third cylinder 23, first cylinder 21 outer wall is equipped with the external screw thread, second cylinder 22 is the smooth surface with the 23 outer wall of third cylinder, just the radius of a cylinder 21, second cylinder 22 and third cylinder 23 is steadilyd decrease one by one, cabin seat 3 is the pie structure, and it sets up in 2 lower extremes of cabin stem, and with the lower extreme seamless connection of third cylinder 23.

Referring to fig. 2, in order to limit the upper limit of the air pressure inside the cabin and prevent the air from leaking, a first shaft hole 24 is formed in the first cylinder 21, a second shaft hole 25 is formed in the second cylinder 22 and the third cylinder 23, the second shaft hole 25 extends into the first cylinder 21, and the diameter of the first shaft hole 24 is smaller than that of the second shaft hole 25.

Referring to fig. 1 and 2, in order to set different levels of pressure, the radius of the first cylinder 21 is 30mm, the radius of the second cylinder 22 is 24mm, and the radius of the third cylinder is 18mm

Referring to fig. 4, for the convenience of connection, the screw shaft is fixed, and the inner wall of the second shaft hole 25 is provided with internal threads, and the whole internal threads penetrate through the cabin 1.

Referring to fig. 3, the chamber 3 has a thickness of 8mm and a diameter of 20mm in order to increase the pressure. The internal middle image is upwarped, the upwarp degree is small, and the angle is about 30 degrees.
