Description

Technical Field

[0001] The utility model relates to the technical field of flow-through joints, in particular to a flow-through joint. Background Art

[0002] The peripheral parts of the engine include the intake system, fuel system, ignition system, cooling system, lubrication system, exhaust system, transmission system and auxiliary parts. These parts need to be connected through pipes and flow joints. A flow joint is a pipe fitting that connects pipes of different diameters or different types. It can connect pipes of different materials, or pipes of the same material but different diameters. The function of the flow joint is to connect the pipes to ensure the connectivity and integrity of the entire pipe system. It also plays a role in regulating the flow rate, reducing the impact of sudden changes in the pipe on the fluid, and reducing pipe vibration and noise.

[0003] Based on the above, the inventors have discovered the following problems: most of the current flow joints are composed of a joint seat and a pipe body, and the joint seat and the pipe body are mostly integral structures, and the pipe body and the joint seat cannot be disassembled, resulting in a limitation on the diameter of the pipe body on the flow joint. When the size of the pipe to be flow-connected is inconsistent with the size of the pipe body on the flow joint during the pipeline connection process, the flow joint needs to be replaced, which affects the installation efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a current-passing joint is provided to achieve a purpose with greater practical value. Utility Model Content

[0007] Furthermore, a circular plate is sleeved on the outside of the push rod, and a third spring is movably sleeved on the outside of the push rod, and two ends of the third spring are fixedly connected to one end of the circular plate and one end of the cylinder respectively.

[0008] Furthermore, both sides of the outer portion of the push rod are provided with sliding grooves, and both sides of the inner wall of the cylinder are provided with sliding bars, and the sliding bars and the sliding grooves are matched with each other and are slidably connected.

At this time, the pair of second positioning holes on the mounting head limit groove correspond one to one with the first positioning hole on the connecting head limit strip, and then by rotating the push rod, the cylinder is driven to rotate inside the mounting frame under the matching action of the slide bar and the slide groove, the angle of the positioning block is adjusted to align and match the positioning block with the first positioning hole and the second positioning hole, and the push rod is slowly pulled upward to move the positioning block upward.

[0019] The beneficial effect of adopting the above further solution is that by providing a sealing gasket, and the two sides of the sealing gasket respectively abut against the mounting head and the connecting head, the sealing between the mounting head and the connecting head is improved.

[0020] Furthermore, a flow hole is provided inside the joint seat, and connecting pipes are installed at the upper end and the bottom end of the joint seat near the flow hole, and threads are provided inside the connecting pipes.

[0021] The beneficial effect of adopting the above further solution is that by providing a connecting pipe and providing threads inside the connecting pipe, it is convenient to connect the connecting pipe with other fluid pipelines.

[0022] The beneficial effects of the utility model are as follows: the utility model provides a flow joint obtained by the above design. When it is necessary to disassemble the joint seat and the pipe body after plugging and connecting, the mounting head and the connecting head are movably plugged in, so that the limiting strip of the connecting head is located inside the limiting groove of the mounting head, so that the pair of second positioning holes are respectively located at the upper part and the bottom part of the first positioning hole. At this time, the pair of second positioning holes on the limiting groove of the mounting head correspond one to one with the first positioning hole on the limiting strip of the connecting head.
