Abstract
The utility model relates to the technical field of plastic pipes, in particular to an R expanded port quick-connection plastic pipe. The R expanded port quick-connection plastic pipe comprises a plastic pipe body, one end of the plastic pipe body is provided with a pipe cavity thickening structure, and the second end of the plastic pipe body is provided with an outer pipe wall necking structure. The R expanded port quick-connection plastic pipe is characterized in that the outer side of the outer pipe wall necking structure is provided with a groove surrounding the outer pipe wall by one circle, a rubber loop is arranged inside the groove, a thickened hunching structure is arranged inside the pipe cavity thickening structure and is arranged inside a pipe cavity by one circle, a rubber ring in interference fit with the rubber loop is arranged inside the hunching structure, the outer portion of the end portion of the second end is provided with a chamfer structure, the chamfer ranges from 45 degrees to 30 degrees, the angle formed between the plane of the end portion of the second end and the axis of the plastic pipe body is of a structure with the angle ranging from 30 degrees to 45 degrees, and the plastic pipe has the advantages of being convenient to use, good in airtight performance and capable of achieving quick connection.
Description
Technical field
The utility model relates to plastic tube technical field.
Background technique
In order to realize when plastic tube is installed, can connect fast, the technological scheme of taking in prior art is such: plastic tube one end has the structure of tube chamber chap, the other end has the structure that outer tube wall attenuates, during installation, intert and connect, when such plastic tube is installed, also want gluing, there is the shortcoming of poor air-tightness.
Summary of the invention
The purpose of this utility model will overcome above-mentioned shortcoming exactly, provides a kind of R enlarging easy to use, that tightness is good to connect soon plastic tube.
The technical solution of the utility model is achieved in that a kind of R enlarging connects plastic tube soon, comprise plastic tube body, plastic tube body one end has the structure of tube chamber chap, the second end has the structure that outer tube wall attenuates, it is characterized in that: the structure outside that described outer tube wall attenuates has around the outer tube wall groove of a week, has rubber ring in groove.
In the structure of tube chamber chap, also have the ridge structure of chap, ridge structure is to arrange for one week in tube chamber, has the rubber ring with rubber ring interference fit in ridge structure.
Say further, the second described outside, end end has chamfering structure.
Preferably, the chamfering of the second described outside, end end is 45-30 degree.
Further say, the angle that the face of the second described end end becomes at axis with plastic tube body is the structure of 30-miter angle.
The beneficial effects of the utility model are: such plastic tube have advantages of easy to use, tightness good, can realize soon and connecing.
Accompanying drawing explanation
