In the face of such risks, it is required that the operator in the production process should monitor the product size regularly to ensure its qualification, which not only increases the labor intensity of the staff, but also reduces the production efficiency.

[0003] Moreover, during on-site construction, there are different pipe sizes between different equipment, which cannot be directly installed, and specific size conversion joints need to be selected for conversion, which also greatly increases the cost and improves the assembly difficulty. In view of the above-mentioned insufficient versatility between pipe and pipe fittings due to tolerance and size difference, there is an urgent need for a component to adaptively connect pipe and pipe fittings with certain size deviation. SUMMARY

[0038] Through this setting mode, when the user needs to connect the pipes of different diameters, the user first inserts the two pipes to be connected through receiving pipe 1, then inserts the clamping pawl 12 of receiving pipe 1 into adjusting pipe 2, in the process of inserting, the inner wall of adjusting pipe 2 extrudes clamping pawl 12, so that clamping pawl 12 clamps the pipe to be connected, then the card claw and receiving pipe 1 are fixed through thread connection or clamping mode, and the installation can be completed, the above operation is carried out on the pipe to be connected 3 at both ends of adjusting pipe 2, and the two incompatible pipes can be connected together, the pipe joint assembly can be compatible with a plurality of different sizes of pipes, greatly improves the versatility between pipe and pipe, and is convenient to operate, without special equipment, improves the efficiency of pipe assembly.

[0039] As an embodiment of the utility model, the outer side of clamping pawl 12 is provided with external thread structure, the inner wall of adjusting pipe 2 is provided with internal thread structure, and receiving pipe 1 is threadedly connected with adjusting pipe 2 through clamping pawl 12.

[0040] With this setup, when the size of the receiving pipe 1 needs to be adjusted to clamp the pipe 3 to be connected, the jaws 12 of the receiving pipe 1 are screwed into the inner wall of the adjusting pipe 2. During the screwing process, the inner wall of the adjusting pipe 2 gradually presses the jaws 12, causing the jaws 12 to contract and clamp the pipe 3 to be connected through the receiving pipe 1. After the jaws 12 clamp the pipe 3 to be connected, the jaws 12 can no longer contract, thus making the external thread on the jaws 12 and the internal thread on the adjusting pipe 2 tightly connected, improving the stability of the connection.

[0041] Example 2

[0049] As an embodiment of the utility model, the first boss 121 is provided with a slope 1211 on the side towards the end of the receiving pipe 1.

[0050] Through the setting mode, when the receiving pipe 1 is inserted, the first boss 121 may deviate and fail to be directly opposite the channel 22, at this time, the first boss 121 and the second boss 21 interact, at this time, the first boss 121 contacts the slope structure on the second boss 21, which is convenient for reducing the resistance of the first boss 121 in the insertion process, makes the insertion process of the first boss 121 more smooth, and improves the convenience of installation.

[0051] As an embodiment of the utility model, the second boss 21 extends along the circumferential direction of the adjusting pipe 2, and the plurality of second bosses 21 are equidistantly arranged along the axial direction of the adjusting pipe 2.

[0052] Through the setting mode, the adjusting pipe 2 is provided with corresponding second bosses 21 at different depths, after the user inserts the receiving pipe 1 into the adjusting pipe 2 to the appropriate depth, the receiving pipe 1 is rotated, the first boss 121 is clamped with the second boss 21 of the corresponding depth, and the fixed connection between the receiving pipe 1 and the adjusting pipe 2 is completed.

[0054] The following is a third embodiment of the utility model of the adjustable pipe joint assembly, which is similar to the first embodiment, and the difference lies in that the deformation groove 11 and the claw piece 12 are further limited.

[0055] As an embodiment of the utility model, the plurality of deformation grooves 11 are equidistantly distributed along the circumferential direction of the receiving pipe 1.

[0056] Through the setting mode, the equidistantly distributed deformation grooves 11 are favorable for making the receiving pipe 1 deform uniformly, reducing stress concentration after installation of the receiving pipe 1, and improving the service life of the pipe fitting.

[0057] As an embodiment of the present application, the claw pieces 12 are provided with four pieces.
