Quick pipe joint

Abstract

The invention provides a quick pipe joint, which is used for quickly connecting a low-pressure compressed air pipeline. In order to realize conveying of compressed air, most conventional joints can only be used together with matched pipes, namely, a large-caliber pipe is matched with a large joint, a small-caliber pipe is matched with a small joint and the large and small joints cannot replace each other. A compressed air output joint is provided with a metal guide pipe; the tail end of the guide pipe, namely, a compressed air input direction, is provided with a rubber pipe; a compressed air input joint is provided with a pneumatic needle; and the pneumatic needle is pushed into a flattened rubber pipe, so that compressed air flows inwards from a hollow pneumatic needle and a communicating process is finished. Simultaneously, the compressed air output joint is provided with a shoulder port and the input joint is provided with a hook, so that the compressed air output joint and the input joint are prevented from falling.

Description

Technical field: [0001] The invention relates to a quick pipeline connector, which is used for quick connection of low-pressure compressed air pipelines. Background technique: [0002] Compressed air is a common tool in industrial production. In order to realize the delivery of compressed air, there are now various types of joints, but most of the existing joints can only be used in matching models. Large-diameter pipes are equipped with large joints, and small-diameter pipes Equipped with small joints, the large and small joints cannot be mixed, so that some stations in the workshop are equipped with multiple compressed air joints of different calibers for the setting of different air consumption. Invention content: [0003] In order to solve the problem that the existing pipe joints of large and small diameters must be matched and cannot be used together, resulting in inconvenient use, the present invention proposes a quick pipe joint. There is a rubber tube at the end ...

Problems solved by technology

[0003] In order to solve the problem that the existing pipe joints of large and small diameters must be matched and cannot be used together, resulting in inconvenient use, the present invention proposes a quick pipe joint. There is a rubber tube at the end of the tube, that is, in the direction of compressed air input. One end of the rubber tube is set on the guide tube, and the other end extends in the direction of compressed air input. When the joint is not in use, the rubber tube is compressed by the compressed air. The rubber tube blocks the overflow of compressed air
