Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic pipe joints, and more specifically to a quick-insertion pneumatic pipe joint. Background Art

[0002] Pipe fittings are the connection tools between pipes and are the detachable connection points between components and pipes. They play an indispensable role in pipe fittings and are one of the two main components of pipes. There are many types of pipe fittings. Commonly used pipe fittings can generally be divided into two types: hard pipe fittings and hose fittings. Most of the hose fittings used in pneumatic pipelines are hose fittings, which are generally crimped hose fittings. Existing hose fittings generally include ferrules, flaring cores, flaring sleeves, flaring nuts, etc., which have complex structures and are inconvenient to disassemble and assemble. They are not conducive to rapid installation and disassembly in narrow spaces and are not very convenient to use.

[0003] The prior art discloses a Chinese utility model quick-plug pneumatic pipe fitting with publication number CN203797207U. The utility model has a reasonable structure. The PU hose can be directly inserted into the pipe fitting to be connected thereto. The front end of the PU hose is inserted and contacts the step four on the elbow. When the disc spring is reset, the edge of its inner ring is clamped into the outer wall of the PU hose to achieve fixation, and the sealing ring is in contact with the outer wall of the PU hose to maintain air tightness. However, the fixing and removal of the hose is mainly achieved by pressing a button. Therefore, when in use, it is very easy to press the component by mistake, thereby causing the hose to detach from the pneumatic pipe fitting during use. In addition, the button and the core sleeve are fixed and clamped by several steps, so the components are difficult to separate. When a component is damaged, it is difficult to replace and repair. Therefore, the present application proposes a quick-plug pneumatic pipe fitting. Utility Model Content
