Embodiment Construction

[0019] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0020] The embodiment structure of the scheme of the present invention is by figure 2 shown. There is a pipe shaft 2 with a fluid passage in it. After the present invention is connected to the pipeline to be connected, the fluid passage communicates with the passage of the connected pipeline to reliably connect the entire pipeline. The pipe shaft 2 The right end has a threaded section for connection, which is generally connected with a pressure reducing valve when it is used to connect the gas source pipeline of the gas tank and the gas stove; The limit member 9 that acts as a limit to the outer sleeve 3 is shown as a limit stop ring. The wall of the outer sleeve 3 is provided with a radial through hole 4, and two or three radial through holes 4 can also be provided. A fastener 5 is arranged in the hole 4, and the outer wall surface of the fastener 5 is pr...

Abstract

The pipe joint for quickly-connecting pipeline is characterized by that the outer wall surface of the pipe shaft is equipped with inner sleeve, the outer wall surface of the inner sleeve is equipped with outer sleeve, and the wall of outer sleeve is equipped with fastener with threaded outer wall surface, its outer sleeve also is equipped with handle wheel and spring acting on fastener, and the left part and right part of said spring are respectively tightly-fitted with outer wall surface of right end of inner sleeve and outer wall surface of spacer, and the outer wall surface of the inner sleeve is equipped with groove. The handle wheel is turned to drive the outer sleeve and fastener to make them turn, and when the inside of fastener is fallen intothe groove, the top of thread of its outer wall surface is smooth with outer wall surface of outer sleeve, and when the inside wall surface of fastener is slid to outer wall surface of inner sleeve, the screw-thread of its outer wall surface is projected from outer wall surface of outer sleeve.

Description

technical field [0001] The invention belongs to a quick pipe joint, and is especially suitable for pipe joints that need to be installed and disassembled frequently, such as pipe joints for connecting household gas tanks and gas stove pipes. Background technique [0002] Pipe joints are often connected to the pipes to be connected by the threads at both ends. For example, the connection between the existing household gas stove gas source pipeline and the gas tank, see figure 1 The gas source of the gas cooker is connected through the threaded connection between the threaded member 1 and the interface end of the gas tank. For pipe joints with this type of structure, it is necessary to rotate the threaded member for nearly ten or more turns to satisfy disassembly or reliable connection. The operations of rotation, installation and disassembly are cumbersome and inconvenient to use, and the bayonet phenomenon that occurs can easily damage the connecting thread and affect its ...
