Preferably, a waterproof gasket is provided on the inner wall of the annular groove.

Preferably, there are four clamping blocks, and the gap between two clamping blocks is the same size as the clamping blocks.

Preferably, the thread A is provided on the inner or outer ring of the left pipe joint; the thread B is provided on the inner or outer ring of the right pipe joint.

The beneficial effects of the invention are: the invention can ensure sufficient connection with the pipeline, and the installation and disassembly are easy.

detailed description

The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

Please refer to Fig. 1 to Fig. 5, the embodiment of the present invention comprises:

A pipe joint, comprising: a left pipe joint 1 and a right pipe joint 2; the left pipe joint 1 is cylindrical, the outer ring of one end of the left pipe joint 1 is provided with a thread A, and the left pipe joint 1 connects the thread A with the Pipeline connection, the other end of the left pipe joint 1 is provided with four blocks 3, the blocks 3 are distributed along the outer ring of the left pipe joint 1, the gap between two blocks 3 is the same size as the blocks 3, and the blocks 3 can pass through Block 3 connects the left pipe joint 1 to the right pipe joint 2; the outer ring of the left pipe joint 1 is provided with a regular hexagonal clamping block 4, and the center line of the clamping block 4 is aligned with the left pipe joint 1 The axes are on the same straight line, and the clamping block 4 is located on the left pipe joint 1 between the clamping block 3 and the thread, the clamping block 4 can facilitate the use of a wrench to connect or disassemble the left pipe joint 1 and the pipeline; The right pipe joint 2 is in the shape of a regular hexagonal prism, and the center line of the right pipe joint 2 has a circular through hole, which can ensure the flow of liquid in the pipeline; the outer ring of one end of the right pipe joint 2 is provided with a thread B, The right pipe joint 2 is connected to the pipeline through the thread B, and the other end surface of the right pipe joint 2 is provided with an annular groove, the axis of the annular groove is on the same line as the axis of the circular through hole; Stopper 5, stopper 5 and described clamping block 3 are staggered to be set, and the notch of the same size as clamping block 3 is formed between two described stoppers 5, and clamping block 3 can be stuck in the annular groove by stopper 5; There is a certain distance between the stopper 5 and the inner wall of the annular groove and the bottom of the annular groove, so that the left pipe joint 1 is stuck in the annular groove; a spring 6 is arranged in the annular groove, and one end of the spring 6 is fixed in the annular groove At the bottom of the groove, the other end of the spring 6 abuts against the stopper 5 to ensure the stability of the connection between the left pipe joint 1 and the right pipe joint 2 .
