Air pipeline fast connector

Abstract

The invention discloses an air pipeline fast connector. The air pipeline fast connector comprises two or more embracing hoops, a connecting component and sealing rings, the connecting component is arranged between two embracing hoops and is connected with the embracing hoops, the number of the sealing rings is same as that of the embracing hoops, a circular groove is formed in the connecting portion of each embracing hoop inner wall and the connecting component, the inner diameter of the connecting component end opening enlarges and stretches outward with an arc shape, and a first containing portion is formed; the tail end of the first containing portion stretches outward to form a fitting portion, the fitting portion protrudes outward in the radial direction of the connecting component, the protruding portion extends in the direction far away from the end opening, and a first bulge loop correspondingly embedded with the circular groove in each embracing groove is formed; when the first bulge loop of the connecting component is embedded into the circular groove, a second containing portion is formed between the inner side wall of the circular groove and the end opening of the fitting portion, and each sealing ring is arranged in the second containing portion and is fitted with the end opening of the fitting portion tightly. The air pipeline fast connector has the advantages that the sealing performance is better, the assembly and disassembly are convenient, and ordinary maintenance is more facilitated.

Description

Technical field [0001] The invention relates to a connector, in particular to a quick connector for an air pipe. Background technique [0002] Fluid transportation systems are widely used to transport liquids or gases, such as water and gas. Among them, gasoline or natural gas is a more common example. Fluid transportation systems include fuel or natural gas pipelines that can transport thousands of kilometers, and pipelines that transport fluids. It can be made of different materials, including steel, iron, copper, aluminum and plastic; and the safety of fluid transportation pipelines that are thousands of kilometers long is not only related to the material of the pipeline, but also the installation of the pipeline; especially The connection between the straight-through pipeline and the straight-through pipeline, the pipeline needs to bend, and the fluid divider; the connection of the fluid conveying pipeline, the traditional method is to weld two metal pipelines, but most of th...

Problems solved by technology

[0003] In the fluid pipeline quick connector mentioned above, the two ends of the metal shell are used to connect to the pipeline to be connected, but since there is only one sealing device inside the metal shell, the connection between the pipeline to be connected and the metal shell is not sealed. In place, so the sealing effect is not ideal; moreover, for the connection between the straight-through pipeline and the straight-through pipeline, where the pipeline needs to turn and the fluid diversion, etc., it is necessary to prepare corresponding metal shells and sealing devices, so the template made Many, cumbersome process, high cost
