In order to overcome the defects in the prior art, the utility model aims to provide the pipe joint with good sealing performance and deformation resistance.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
an anti-deformation pipe joint comprises a first connecting piece, a second connecting piece and a compression screw sleeve, wherein a pipeline channel is arranged in the middle of the first connecting piece; the outer ends of the first connecting piece and the second connecting piece are fixedly connected with pipelines on two sides respectively, and the inner ends of the first connecting piece and the second connecting piece are butted with each other; the outer surface of the first connecting piece is provided with a clamping table, the outer surface of the second connecting piece is provided with external threads, one end of the compression screw sleeve is sleeved on the second connecting piece through threads, and the other end of the compression screw sleeve is abutted to the clamping table; the inner surface of the abutting end of the first connecting piece is a conical surface; the outer surface of the butt joint end of the second connecting piece is a spherical surface; the outer surface of the abutting end of the second connecting piece abuts against the inner surface of the abutting end of the first connecting piece to form ball cone sealing; the inner surface of the butt joint end of the second connecting piece is provided with a caulking groove perpendicular to the axis of the pipeline, and the caulking groove is embedded with a compression-resisting ring which is matched with the caulking groove in shape.
Preferably: the cross section of the caulking groove is an isosceles trapezoid with a small upper part and a large lower part, and the side edges of the two vertex angles are arc-shaped curved surfaces for transition.
Preferably: the middle part of the inner side surface of the compression-resistant ring is provided with a supporting part protruding inwards.
Preferably: the inner diameters of pipelines at two ends (M/N sections of pipelines in the illustration) of the second connecting piece are conical pipe diameters with small inner diameter and large outer diameter.
According to the utility model, the compression-resistant ring structure is designed in the compressed second connecting piece, so that the inner wall of the second connecting piece cannot be micro-deformed even in long-term stressed use, and the sealing effect and the service life are improved. The structural design of the anti-compression ring matched with the caulking groove structure and the pipeline inner diameter design of the second connecting piece enable the installation and the disassembly of the anti-compression ring to be very convenient, and the caulking groove can be pressed in/extruded out by the anti-compression ring through the structural design of the supporting part and the impact of the supporting part through the installation pipe from one side.

Detailed Description
The structure and principles of the present utility model are fully described in connection with specific embodiments so that those skilled in the art may fully understand and practice the utility model.
As shown in fig. 1, 2 and 3, the deformation-preventing pipe joint comprises a first connecting piece 1, a second connecting piece 2 and a compression screw sleeve 3, wherein a pipeline channel is arranged in the middle of the first connecting piece; the outer ends of the first connecting piece 1 and the second connecting piece 2 are fixedly welded with pipelines on two sides respectively, and the inner ends are mutually butted; the outer surface of the first connecting piece 1 is provided with a clamping table 11, the outer surface of the second connecting piece 2 is provided with an external thread 21, one end of the compression screw sleeve 3 is sleeved on the second connecting piece 2 through threads, and the other end of the compression screw sleeve is abutted against the clamping table 11; the inner surface of the abutting end of the first connecting piece 1 is a conical surface or a spherical surface; the outer surface of the butt joint end of the second connecting piece 2 is a conical surface or a spherical surface; the outer surface of the abutting end of the second connecting piece 2 abuts against the inner surface of the abutting end of the first connecting piece 1 to form conical surface sealing, spherical surface sealing or ball cone sealing; the inner surface of the butt joint end of the second connecting piece 2 is provided with a caulking groove perpendicular to the axis of the pipeline, and the caulking groove is embedded with a compression ring 4 which is matched with the caulking groove in shape. In order to facilitate the fixed connection of the first connecting piece 1 and the second connecting piece 2 with the adjacent pipelines, the pipelines at the outer ends of the connecting pieces can be designed into a conical shape or a step shape as shown in the figure.
Because the butt joint end of the second connecting piece 2 is positioned on the inner side of the butt joint end of the first connecting piece 1, the butt joint end of the second connecting piece 2 is frequently stressed in long-term use, and micro deformation of the butt joint end of the second connecting piece 2 can be effectively reduced through the design of the anti-compression ring 4, and the leak tightness reduction or the pipe joint deformation caused by long-term use is prevented.
