Description
Technical Field
[0001] The utility model relates to a male joint structure which can improve the airtight effect and the flow guiding effect of a quick joint. Background Art
[0002] A quick joint commonly used for connecting pipelines for transmitting fluids (such as liquids or gases) is mainly a joint that allows users to quickly connect or disconnect the pipelines without using tools. The quick joint mainly includes a male joint and a female joint. The male joint is connected to the upstream pipeline, and the female joint is connected to the downstream pipeline. Among them, when the male joint and the female joint are disconnected and inserted into each other, the opening and closing of the internal valve body assembly can be controlled, thereby determining the flow of the pipeline fluid. Usually, the fluid flowing through the male joint and the female joint is high-pressure fluid. Therefore, if the bonding strength between the male joint and the female joint is weak, it is easy to be separated under the action of the fluid pressure in the pipeline; or when the internal assembly gap between the male joint and the female joint is too large, the airtight effect cannot be achieved, and the fluid is likely to leak out.
