Accompanying drawing explanation
Fig. 1 is the structure sectional view of this utility model pipeline sealing device；
Fig. 2 is the part-structure sectional view of this utility model sealing ring.
Detailed description of the invention
By feature of the present utility model, technological means and the specific purposes reached, merit can be further appreciated that
Can, with detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, this utility model pipeline sealing device includes the first pipeline 100, sealing ring
200 and second pipe 300, described sealing ring 200 lateral part and the laminating of the first pipeline 100 are arranged, described close
Seal 200 medial part is arranged with second pipe 300 laminating.
Described sealing ring 200 includes the first contact site 210 and the second contact site 220, described first contact site
210 and the second one-body molded setting of contact site 220, described first contact site 210 external diameter is less than the second contact site
220 external diameters, described first contact site 210 and the second contact site 220 lateral part are respectively arranged with screw-like structure
Threaded portion 230, described sealing ring 200 is fitted tightly with the first pipeline 100 medial part by threaded portion 230.
Described second contact site 220 medial wall protrudes out along the first contact site 210 direction and is provided with snap fit 240, described
Snap fit 240 and the second contact site 220 medial part enclose to set and are formed with draw-in groove 241, outside described second pipe 300
Portion and snap fit 240 fit tightly setting, due to the elastic construction of snap fit 240 so that snap fit 240 is second
Produce deformation under the squeezing action of pipeline 300 lateral part, and then support at second pipe 300 lateral part, the
When two pipelines 300 are intended to depart from the first pipeline 100 can by the opposition of the snap fit 240 of sealing ring 200,
