Embodiment Construction

[0028] (first embodiment)

[0029] will now combine Figure 1-7 The first embodiment of the present invention will be described.

[0030] The pipe joint device according to the first embodiment of the present invention is constructed such that figure 1 and 5 As shown, the first pipe member 2 having the male fitting is engaged with the pipe fitting member 10 through the window portion 38 formed on the second pipe fitting member 3 having the female fitting. The pipe joint member 10 is mounted on the second pipe member 3 .

[0031] The first pipe member 2 is formed in a cylindrical shape to allow refrigerant to flow, and the tip of the insertion side thereof is formed as a male-side joint part (male joint) 22 whose diameter is opposite to the cylindrical part 21 is increased. The joint portion 22 is provided with a groove 23 in which an O-ring 5 as an airtight member is mounted, and an engaged member 24 (engaged portion) formed into a substantially cylindrical shape is provi...

Abstract

A piping joint device for connecting a first piping member having a male joint and a second piping member having a female joint includes: a piping joint member provided with a plurality of diametrically deformable engagement portions; and a plurality of window portions provided in an extension cylinder portion of the second piping member to be engaged with the engagement portions. The male joint of the first piping member is inserted into the female joint of the second piping member in one touch by using deformation of the engagement portions, and a detent portion is provided at an engagement position where the engagement portions engage with the first piping member to prevent a rotation.

Description

technical field [0001] The present invention relates to a pipe fitting arrangement comprising a first fluid pipe member having a male fitting and a second fluid pipe member having a female fitting for connecting. The pipe joint device is suitable for application in, for example, pipe joints of refrigerant pipe components of a vehicle air-conditioning refrigeration cycle. Background technique [0002] Conventionally, in this type of pipe fitting device, there is a pipe fitting for connecting a first fluid piping member having a male fitting and a second fluid piping member having a female fitting, the fitting having a pair of first narrow The first slot is formed at a position opposite to the axis of one end of the cylindrical body. In addition, engaging portions protruding toward the shaft are formed at a plurality of positions on the circumferential thin-walled portions at both ends of the main body, and the first slot or the second slot is not formed thereon. [0003] Th...
