Embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model being described further and illustrating.
The concrete structure of the utility model embodiment as shown in Figures 1 to 4.
As depicted in figs. 1 and 2, fluid line ready-packaged joint comprises the first pipe joint 11 and is locked and the second pipe joint 12 be communicated with the first pipe joint 11 for inserting in the first pipe joint 11.
As shown in Figure 1, the second pipe joint 12 comprises the cylindrical part 121 for inserting in the first pipe joint 11.As shown in Figure 2, the first pipe joint 11 is provided with the passage 111 of the cylindrical part 121 for holding the second pipe joint 12, is provided with seal ring 20 in passage 111.As shown in Figure 2, when the second pipe joint 12 inserts the first pipe joint 11, seal ring 20 is clipped between passage 111 inwall and cylindrical part 121 outer wall, and is drive fit between passage 111 inwall and seal ring 20 outer wall, between cylindrical part 121 outer wall and seal ring 20 inner hole wall.
As shown in Figure 1, insert on the direction of insertion A of the first pipe joint 11 at the second pipe joint 12, cylindrical part 121 outer wall is with the tapering being greater than zero and the front end external diameter of cylindrical part 121 is less than rear end external diameter.Particularly, the tapering of cylindrical part 121 outer wall of the second pipe joint 12 is 1 degree.In other embodiments, cylindrical part outer wall range of taper is 1 degree to 10 degree, if the radial dimension of the second pipe joint is comparatively large, just cylindrical part outer wall can be made comparatively steep-taper.
As shown in Figure 3 and Figure 4, the cross section of seal ring 20 is Y-shaped.Particularly, insert on the direction of insertion A of the first pipe joint 11 at the second pipe joint 12, front end 21 internal diameter of seal ring 20 is less than rear end 22 internal diameter, and front end 21 external diameter of seal ring 20 is larger than rear end 22 external diameter, and front end 21 end face of seal ring 20 is provided with groove 23.In the present embodiment, the shape of cross section of groove 23 is wide at the top and narrow at the bottom trapezoidal, and in other embodiments, the shape of cross section of groove can be del.The effect of offering groove 23 is the elasticity improving seal ring 20 front end 21, avoids seal ring 20 front end 21 elasticity not enough and causes and be difficult to insert.On the other hand, when fluid pressure in the first pipe joint 11 and the second pipe joint 12 increases, the pressure that liquid produces in the groove 23 of seal ring 20 front end surface also can increase, groove 23 two side radial force increases, thus seal ring 20 front end can radially further expand, can become more tight between cylindrical part 121 outer wall of seal ring 20 and the second pipe joint 12, passage 111 inwall of the first pipe joint 11, sealing strengthens, and that is to say that the larger sealability of fluid pressure is better.
As depicted in figs. 1 and 2, in the present embodiment, seal ring 20 has two and the centre of two seal rings 20 is provided with isolating ring 30, and the groove 23 of two seal rings 20 towards all with direction of insertion A in the same way.
As depicted in figs. 1 and 2, in addition, fluid line ready-packaged joint also comprises the limited ring 50 for preventing seal ring 20 from departing from passage 111.Limited ring 50 is clipped between cylindrical part 121 outer wall of passage 11 inwall and the second pipe joint 12.A in the direction of insertion inserting the first pipe joint 11 at the second pipe joint 12, limited ring 50 is located at the rear of second seal ring 20.
As depicted in figs. 1 and 2, in addition, fluid line ready-packaged joint also comprises the flexible locking ring 40 for being fixed on by the second pipe joint 12 in first pipe joint 11.Second pipe joint 12 is provided with the bulge loop 122 for coordinating to fix the second pipe joint 12 with locking ring 40.When the second pipe joint 12 inserts in the first pipe joint 11, locking ring 40 is fixed in the first pipe joint 11 and locking ring 40 and bulge loop 122 are supported mutually.The concrete structure of locking ring 40 is identical with the elastic card claw structure of Chinese patent CN201748083U, or can with reference to the locking ring structure of Chinese patent CN1916474A.
More than state only with embodiment to further illustrate technology contents of the present utility model; so that reader is easier to understand; but do not represent mode of execution of the present utility model and be only limitted to this, any technology done according to the utility model extends or recreation, all by protection of the present utility model.
