Abstract
The utility model aims at providing a plastic pipe connection structure with a good and reliable sealing property. The plastic pipe connection structure disclosed by the utility model comprises a first plastic pipe connection end and a second plastic pipe connection end, and matched flanges are respectively arranged on the first plastic pipe connection end and the second plastic pipe connection end. The plastic pipe connection structure is characterized in that a taper pipe is arranged at the outer side of the flange on the first plastic pipe connection end; a taper hole matched with the taper pipe is arranged at the end part of the second plastic pipe connection end; when the first plastic pipe connection end and the second plastic pipe connection end are connected, the taper pipe at the first plastic pipe connection end is firstly inserted into the taper hole at the second plastic pipe connection end, and then the first plastic pipe connection end and the second plastic pipe connection end are fastened together by the flanges. The contact area of the first plastic pipe connection end and the second plastic pipe connection end is increased by the taper pipe and the taper hole, so that the sealing property can be effectively improved, and the reliability is improved.
Description
Technical field
The utility model 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 a large amount of application.Connection way between traditional plastic tube is to utilize flange that two sections plastic tubes are directly connected, because plastics easily deform, therefore between flange and the plastic tube and the gap between the plastic tube of two ends is difficult to sealing, cause easily the joint to leak or leak gas, this can bring certain potential safety hazard to engineering, has seriously limited the application area of plastic tube.
The model utility content
The purpose of this utility model is to propose a kind of good seal performance, reliable plastic tube linkage structure.
Plastic tube linkage structure of the present utility model comprises the first plastic tube connecting end and the second plastic tube connecting end, be respectively equipped with the flange that cooperatively interacts on described the first plastic tube connecting end, the second plastic tube connecting end, it is characterized in that described the first plastic tube connecting end is provided with conical pipe in the outside of its flange, the end of described the second plastic tube connecting end is the cone shape hole that cooperates with described 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 described conical pipe is provided with the multiple tracks bulge loop.
Plastic tube linkage structure of the present utility model has effectively been improved the sealability of plastic tube linkage structure, and has been improved reliability by 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 utility model.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and working principle etc. are described in further detail.
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 described 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 and cone shape hole 22 have increased the area of contact of the first plastic tube connecting end 1 and the second plastic tube connecting end 2, therefore can effectively improve sealability, and improve reliability.
