Abstract
The invention aims at providing a plastic pipe connecting structure which is good and reliable in sealing property. The plastic pipe connecting structure provided by the invention comprises a first plastic pipe connecting end and a second plastic pipe connecting end, and flanges matched with each other are respectively arranged on the first plastic pipe connecting end and the second plastic pipe connecting end. The plastic pipe connecting structure is characterized in that the first plastic pipe connecting end is provided with a cone-shaped pipe at the outer side of the flange, and the end of the second plastic pipe connecting end is provided with a cone-shaped hole matched with the cone-shaped pipe. When the first plastic pipe connecting end and the second plastic pipe connecting end are connected with each other, the cone-shaped pipe of the first plastic pipe connecting end is firstly inserted into the cone-shaped hole of the second plastic pipe connecting end, and the first plastic pipe connecting end and the second plastic pipe connecting end are fastened together by the flanges. The contact area between the first plastic pipe connecting end and the second plastic pipe connecting end can be enlarged due to the cone-shaped pipe and the cone-shaped hole, so that the sealing property can be effectively improved and the reliability can be improved.
Description
Technical field
The present invention relates to a kind of plastic tube linkage structure.
Background technique
Plastic tube has that cost is low, flexible, the characteristics of easy construction, has therefore obtained number of applications.Connection way between the conventional plastic pipe is to utilize flange that two sections plastic tubes are directly connected; Because plastics are prone to deform; Therefore between flange and the plastic tube and the gap between the plastic tube of two ends is difficult to sealing; Cause the joint to leak or leak gas easily, this can bring certain potential safety hazard to engineering, has seriously limited the application area of plastic tube.
Summary of the invention
The objective of the invention is to propose a kind of good seal performance, reliable plastic tube linkage structure.
Plastic tube linkage structure of the present invention comprises the first plastic tube connecting end and the second plastic tube connecting end; Be respectively equipped with the flange that cooperatively interacts on the said first plastic tube connecting end, the second plastic tube connecting end; It is characterized in that the said first plastic tube connecting end is provided with conical pipe in the outside of its flange, the end of the said second plastic tube connecting end is the cone shape hole that cooperates with said conical pipe.
When connecting the first plastic tube connecting end and the second plastic tube connecting end; At first the conical pipe with the first plastic tube connecting end inserts in the cone shape hole of the second plastic tube connecting end; And then utilize flange that the first plastic tube connecting end and the second plastic tube connecting end are tightened together; Because conical pipe and cone shape hole have increased the area of contact of the first plastic tube connecting end and the second plastic tube connecting end, therefore can effectively improve sealability, and improve reliability.
Further, for improving sealability, the outer surface of said conical pipe is provided with the multiple tracks bulge loop.
Plastic tube linkage structure of the present invention has effectively been improved the sealability of plastic tube linkage structure, and has been improved reliability through conical pipe and cone shape hole are set, and has good practicability.
Description of drawings
Fig. 1 is the structural representation of plastic tube linkage structure of the present invention.
Embodiment
Contrast accompanying drawing below; Through the description to embodiment, the effect of mutual alignment between the shape of specific embodiments of the invention such as related each member, structure, the each several part and annexation, each several part and working principle etc. are done further to specify.
Embodiment 1:
As shown in Figure 1, the plastic tube linkage structure of present embodiment comprises that the first plastic tube connecting end 1 and the second plastic tube connecting end, 2, the first plastic tube connecting ends 1 are provided with flange 11, and is provided with conical pipe 12 in the outside of flange 11; The end of establishing flange 21, the second plastic tube connecting ends 2 that cooperate with flange 11 on the second plastic tube connecting end 2 is the cone shape hole 22 that cooperates with said conical pipe 12.
When connecting the first plastic tube connecting end 1 and the second plastic tube connecting end 2; At first the conical pipe 12 with the first plastic tube connecting end 1 inserts in the cone shape hole 22 of the second plastic tube connecting end 2; And then utilize flange 11,21 that the first plastic tube connecting end 1 and the second plastic tube connecting end 2 are tightened together; Because conical pipe 12 has increased the area of contact of the first plastic tube connecting end 1 and the second plastic tube connecting end 2 with cone shape hole 22, so can effectively improve sealability, and improve reliability.
