The invention discloses a pipe threaded flexible joint, which comprises a movable head, a two-way pipe and a rotating handle, wherein the movable head sleeves the two-way pipe, the rotating handle isarranged above the movable head, a first pipeline and a second pipeline are symmetrically arranged in the two-way pipe, the first pipeline is provided with a first butt-joint convex head on one end close to the second pipeline, the second pipeline is provided with a second butt-joint convex head on one end close to the first pipeline, the first pipeline and the second pipeline are connected by means of the first butt-joint convex head and the second butt-joint convex head, the outer side of a connecting region between the first butt-joint convex head and the second butt-joint convex head is provided with an upper fixing ring and a lower fixing ring, each of the upper fixing ring and the lower fixing ring is provided with a fixing device on one end away from the connecting region, and eachfixing device comprises a fixing block. The pipe threaded flexible joint has the beneficial effects that the first pipeline and the second pipeline are movably connected, can fix the connecting region, and can release the connecting region, thereby achieving the effect of facilitating disassembly.
Description
technical field [0001] The invention relates to a pipe thread joint, in particular to a pipe thread active joint. Background technique [0002] Joints such as two-way pipes, three-way pipes, etc. are widely used in production and life, and are indispensable components in various water, gas, and oil circuits. However, when connecting with pipelines, unions are generally used. [0003] In Chinese patent CN 201696759 U, a pipe threaded joint includes a multi-way pipe, a joint head and a sealing ring, and the joint head is sleeved on the end of the multi-way pipe; The card slot, the sealing ring is fixedly connected to the card slot; the inside and outside of the end of the multi-way pipe are provided with bumps or ring-shaped protrusions; or ring-shaped protrusions. The pipe thread joint of the utility model is easy to manufacture, flexible to disassemble and use, and can be designed into various forms such as right-angle elbows and tee pipes, and is suitable for various air ...
