Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
According to the cross section structure schematic diagram of the present utility model shown in Fig. 1, figure includes clip 1, close
Seal 2, pipeline 3, partition the 11, first cross section 12, the 4, second cross section, the cross section shape of described clip 1
Shape is c-type, and described clip 1 cross section includes the 11, second cross section 12, cross section, described second cross section 11
For rectangle with rounded corners, described first cross section 12 is connected by a straightway and two oblique line sections, described
Straightway and oblique line section junction are with fillet, and two oblique line Duan Ziyu straightway junctions are gradually expanded form.
Described sealing ring 2 gap of matching with the first cross section 12 of described clip 1 is connected, described clip 1 and pipe
The contact of 3, road connects, and described sealing ring 2 is placed in the gap that described clip 1 matches with described pipeline 3
