Abstract

The utility model provides a concentric joint of a pressing groove. The concentric joint of the pressing groove comprises a body, connecting pipes of unequal pipe diameters which are integrated with the body are arranged at both ends of the body, and the central axes of two connecting pipes of unequal caliber sizes are in a same straight line. Long ring-shaped straight faces of consistent thickness which are formed between the inner walls and the outer walls of the two connecting pipes of the unequal caliber sizes are formed on the inner walls of the connecting pipes, outer ring-shaped groove faces which are convex downwards are arranged on the outer walls of the connecting pipes, and inner ring-shaped convex faces which are convex upwards are arranged on the ring-shaped straight faces in the connecting pipes, corresponding to the outer ring-shaped groove faces. The concentric joint of the pressing groove has the advantages of being capable of being quickly dismantled or installed, low in production cost, and good in sealing performance.

Description

The concentric joint of a kind of indent
Technical field
The utility model relates to a kind of pipe connecting component, particularly a kind of pipe connector.
Background technique
With one heart joint is link a kind of of pipeline, pipe fitting, and its effect is that the seal for pipe joints with different tube diameters couples together, and what the mouth of pipe of the connecting tube of concentric joint of the prior art mostly adopted is that internal thread connects, and its cost of production is high, and installation difficulty is large.
The model utility content
For the deficiencies in the prior art, the utility model provides a kind of indent concentric joint.
To achieve these goals, the technological scheme that its technical problem that solves the utility model adopts is: the concentric joint of a kind of indent, comprise body, the two ends of body are provided with the connecting tube that does not wait with body all-in-one-piece pipe diameter size, the central axis of two connecting tubes that described pipe diameter size does not wait is on the same straight line, the consistency of thickness that forms between the inwall of two connecting tubes that pipe diameter size does not wait and the outer wall and be formed with long annular at the connecting tube inwall and face directly, outer wall at described connecting tube is provided with to recessed outer ring groove face, and the annular in described connecting tube is faced corresponding outer ring groove face directly and is provided with convex interior annular convex surface.
Described interior annular convex surface faces directly with annular and the inwall intersection of connecting tube joins by cambered surface.
Connecting body between two connecting tubes on the described body becomes the hollow round table structure.
The beneficial effects of the utility model: concentric joint of the present utility model can be realized quick-detachment or installation, and cost of production is low, good seal performance.
