Embodiment Construction

[0014] see figure 1 - Figure 4 , to provide a new connection structure between a thin-walled stainless steel pipe 7 and a pipe joint 1. The diameter of the connecting end of the pipe joint 1 is reduced, and its outer wall is provided with two sealing rings 2 and a circular ring in the axial direction from the pipe mouth. Buckle groove 3, each sealing ring 2 is respectively covered on each sealing ring groove 4 provided on the outer wall, and the buckle groove 3 is covered with a ring-shaped buckle 6 with a notch 5, which can act on the notch 5 through a special tool, Put buckle 6 on or remove buckle slot 3. The connecting end port of the stainless steel pipe 7 forms a ring-type clamping position 8 through flaring.

[0015] Specifically, the outer wall of the buckle 6 is provided with an annular rib 9 with a bevel, and the rear side of the rib 9 is close to the inner edge of the ring mouth of the ring-shaped locking position 8, so that the gap between the buckle 6 and the ri...

Abstract

The invention discloses a novel connecting structure of a thin-wall stainless steel pipe and a pipe joint. The pipe diameter of the connecting end of the pipe joint is decreased; a plurality of seal rings and a circular fastener slot are axially and sequentially arranged on an outer wall of the pipe joint from a pipe orifice; each seal ring sleeves on each seal ring slot arranged on the outer wall; an annular fastener with a notch sleeves outside the fastener slot; the end port of the connecting end of the stainless steel pipe is flared to form an annular fastening position; and between the connecting end of the stainless steel pipe and the connecting end of the pipe joint, the seal rings on the outer wall of the connecting end of the pipe joint are in extrusion connection with an inner wall of a smooth surface of the connecting end of the stainless steel pipe, and the fastener of the connecting end of the pipe joint is correspondingly fastened with the annular fastening position of the connecting end of the stainless steel pipe. The connecting structure is simpler in structure, and has better sealability and fastening performance for the connection between the thin-wall stainless steel pipe and the pipe joint so as to achieve an excellent connecting effect.

Description

technical field [0001] The invention relates to a thin-walled stainless steel pipe, in particular to a novel connection structure between a thin-walled stainless steel pipe and a pipe joint. Background technique [0002] Most of the existing thin-walled stainless steel pipes and pipe joints are connected by threads, or the connections are loose, prone to leakage, or have complex structures and high processing costs, which need to be improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new connection structure between a thin-walled stainless steel pipe and a pipe joint. Good connection effect. [0004] In order to solve the above technical problems, the technical solution of the present invention is to provide a new connection structure between a thin-walled stainless steel pipe and a pipe joint. A plurality of sealing rings and circular buckle grooves, each sealing ring is overlaid on the sealing ring gr...
