The invention relates to a compressed air delivery pipeline system, in particular to a crossover coupling of a quick-connection compressed air delivery pipeline and a use method thereof. The crossover coupling of the quick-connection compressed air delivery pipeline comprises a pipe coupling and a clamping member, wherein the pipe coupling comprises a coupling pipe in which a vent hole is arranged; the clamping member is composed of a left clamping shoe and a right clamping shoe; the lower part of the left clamping shoe and the lower part of the right clamping shoe are mutually articulated; the upper part of the left clamping shoe and the upper part of the right clamping shoe are connected by a locking mechanism; the right clamping shoe and the coupling pipe are integrated into a whole; around boss is arranged at the middle of the right clamping shoe; an air inlet is arranged on the end surface of the round boss; the air inlet is communicated with the vent hole in the coupling pipe; a drill hole boss is arranged in a position corresponding to the air inlet on the left clamping shoe; and a drill hole is arranged on the drill hole boss. The invention realizes quick connection between a delivery pipeline with a large pipe diameter and a delivery pipeline with a small pipe diameter, and the product of the invention has the characteristics of simple structure, convenient implementation and firm connection.
Description
technical field [0001] The invention relates to a compressed air delivery pipeline system, in particular to an adapter for quickly connecting compressed air delivery pipelines and a method for using the adapter. Background technique [0002] There are many kinds of pipe joints for connecting compressed air pipes. For example, the applicant applied for a compressed air quick pipe joint (application number: 200810063105.6, application date: 2008-07-10), the pipe joint includes a joint pipe and an end cap, and the end cap and the joint pipe are detachably connected by threads. The end of the pipe is provided with a snap ring seat; the inner end of the snap ring seat extends into the inside of the joint pipe, and a sealing ring is provided against the snap ring seat, and the inner ring of the sealing ring protrudes from the inner diameter of the snap ring seat; the snap ring The outer end surface of the seat is provided with a metal elastic snap ring, the elastic snap ring incl...
