Traditional connection methods usually need to be connected through complex threads or hot melt connection, which requires professional installation tools and skills, and the operation is relatively cumbersome, which is not conducive to quick installation and disassembly.

[0003] The existing water pipe connection technology is complex, time-consuming and laborious, and requires special tools and equipment, which is not conducive to self-operation by ordinary users. In addition, some connection methods need to be fastened with external force, which may cause unstable connection. CONTENT OF THE UTILITY MODEL

[0006] Through the above scheme, since the existing water pipe connection technology is complex, time-consuming and laborious, and requires special tools and equipment, which is not conducive to self-operation by ordinary users, in addition, some connection methods need to be fastened with external force, which may cause unstable connection, by setting the upper clamping block and the lower clamping block, and setting the elastic gasket, the base, the spring and the positioning rod on the upper clamping block, and setting the elastic gasket, the positioning plate and the positioning hole on the lower clamping block, the upper clamping block and the lower clamping block can be quickly and stably connected and installed to the pipeline joint arm, which is simple in operation, stable in connection, avoids the use of special tools or equipment, and is suitable for self-installation by ordinary users, thereby improving the installation efficiency.

[0007] Further, the upper clamping block and the lower clamping block are both semicircular structures, and the upper clamping block and the lower clamping block are movably connected through the hinge.

[0008] Through the above scheme, the upper clamping block and the lower clamping block are connected through the hinge, and then the pipe section arm is quickly clamped and connected.

[0009] Further, the inside of the hinge is slidably inserted with equidistantly arranged bolts, and the outer circumferential surfaces of the bolts are respectively connected with the inner threads of the upper clamping block and the lower clamping block.

[0013] Further, one end of each positioning rod close to the positioning plate is an arc surface structure, and the upper surface of each positioning plate is provided with an inclined slope.

[0014] Through the above scheme, the positioning rod can automatically move to the inside of the base during the rotation and movement process under the joint action of the arc surface and the inclined slope of the positioning plate, thereby automatically completing the butt joint positioning operation of the upper clamping block and the lower clamping block.

[0015] Further, one side of each positioning rod away from the positioning plate is fixedly connected with a spring, and the other end of the spring is fixedly connected with the inside of the base.

[0016] Through the above scheme, the spring can exert a reaction force on the positioning rod, so as to automatically move back and insert into the positioning hole, thereby completing the butt joint positioning operation of the upper clamping block and the lower clamping block.

[0017] Further, the outer circumferential surface of each positioning rod is fixedly connected with a sliding block, and the inside of the base is provided with two sliding grooves, and the outer surfaces of the sliding blocks are slidably connected with the base through the sliding grooves.

[0018] Through the above scheme, the positioning rod is limited to avoid falling off from the inside of the base, and the stability of the movement of the positioning rod is also increased.

[0019] Further, the front surface of each sliding block is fixedly connected with a fixed plate, and the front surface of the fixed plate is fixedly connected with a tab.

[0020] Through the above scheme, the push piece can be simultaneously pushed to move the positioning rod inwards through the fixed plate and the sliding block, so as to move the positioning rod out of the positioning hole and cancel the positioning limitation between the upper clamping block and the lower clamping block.
