This invention relates to the field of tank processing technology, and discloses a tank bottom assembly, a tank, and a method for forming the tank bottom assembly. The tank bottom assembly includes a tank bottom and a transition ring. The transition ring is located at the open end of the tank bottom and is integrally formed with the tank bottom. The outer wall of the transition ring has a first step surface and a second step surface that are vertically arranged. The first step surface is arranged radially along the transition ring, and the outer edge of the second step surface away from the first step surface is inclined towards the outer wall of the tank bottom to form a guide slope. The tank includes a cylindrical section and the aforementioned tank bottom assembly. The method for forming the tank bottom assembly includes the following steps: fixing the outer ring of a constraint plate, and shearing and spinning the plate using a spinning wheel to obtain a first formed part; releasing the outer ring constraint and fixing the inner ring constraint, and flanging and spinning the outer ring using a spinning wheel to form a column section; machining a mating interface on the outer wall of the column section to obtain an integrally formed tank bottom and transition ring. The tank has better quality and lower processing costs.

The utility model belongs to the technical field of connectors, and particularly relates to a quick connector which comprises a body with a connecting hole, a sealing piece capable of forming sealing with an inserted pipeline is arranged in the connecting hole, one side of the sealing piece abuts against a limiting mechanism arranged on the inner side of the connecting hole for limiting, and the other side of the sealing piece abuts against a pressing ring for limiting. A clamping jaw and a sealing cover are arranged on the side, away from the sealing piece, of the pressing ring, the clamping jaw comprises an annular framework arranged between the pressing ring and the sealing cover and a plurality of clamping teeth arranged on the annular framework, supporting clamping teeth protrude from the end, close to the clamping jaw, of the sealing cover to one side of the clamping jaw, and the peripheral face of an annular boss is a circular truncated cone face. And the diameter of the circular truncated cone surface is gradually increased outwards from one side of the clamping jaw. The clamping teeth can be effectively supported, the clamping teeth are prevented from being turned over towards the side away from the pressing ring, a pipeline is effectively clamped, and the pipeline is prevented from being disengaged.
