Abstract

The utility model provides a can prolong type PVC pipe, can prolong type PVC pipe includes the at least two PVC pipes of body, the inner wall of the one end of PVC pipe is equipped with first rubber circle, the outer wall of the other end of PVC pipe is equipped with second rubber circle, first rubber circle with second rubber circle is connected, the one end of PVC pipe is located to first rubber circle, and the one end of another PVC pipe is located to the second rubber circle, and the diameter of another PVC pipe is less than the former PVC pipe, and beneficial effect is as follows: the device has simple structure, makes the extension simpler, collects the pipe sections one by one when not in use, and extends the pipe sections of the sections into a whole longer pipeline when in use.

Description

Extensible PVC pipe

Technical Field

The utility model relates to a pipeline especially designs a can prolong type PVC pipe.

Background

The pipeline is used for conveying gas-liquid media for a long time and is connected through threads. Sealed by a green tape. The pipe connections are often complicated. And water leakage is easily formed at the screw connection position. It is therefore desirable to provide a solution to such technical problems.

Disclosure of Invention

The utility model provides a can prolong type PVC pipe, the aim at of this device of design development, this device simple structure makes to connect long also simpler, and the collection of a festival when not using is long into the longer pipeline of whole root with the tube coupling of festival when using.

The technical scheme is as follows: the utility model provides a can prolong type PVC pipe, can prolong type PVC pipe includes the at least two PVC pipe 1 of body, the inner wall of the one end of PVC pipe 1 is equipped with first rubber circle 2, the outer wall of the other end of PVC pipe 1 is equipped with second rubber circle 3, first rubber circle 2 with second rubber circle 3 is connected, the one end of PVC pipe 1 is located to first rubber circle 2, and second rubber circle 3 locates the one end of another PVC pipe 1, and the diameter of another PVC pipe 1 is less than the former PVC pipe 1, makes two PVC pipe 1 like this be the telescopic machanism that the ring is buckled mutually, and this embodiment has three to connect, and under the state that many PVC pipe 1 were elongated, first rubber circle 2 with second rubber circle 3 takes place the extrusion for the leakproofness between the PVC pipe 1 becomes very good, and the pipeline that forms wholly can regard as the carrier of water. First rubber circle 2, second rubber circle 3 are taper sleeve shape structure, first rubber circle 2 is located the internal diameter of 1 outer mouthful of PVC pipe is less than PVC pipe 1 is kept away from the internal diameter of 1 outer mouthful of PVC pipe, second rubber circle 3 is located the external diameter of 1 outer mouthful of PVC pipe is greater than PVC pipe 1 keeps away from the external diameter of 1 outer mouthful of PVC pipe.

The utility model has the advantages as follows: can not continue behind PVC pipe 1 to be stimulateeed, first rubber circle 2, second rubber circle 3 form mutual extrusion under the effect of tapering under the condition of stimulateeing again to make two PVC pipe 1 connect and more step up, PVC pipe 1's one end is located to first rubber circle 2, and another PVC pipe 1's one end is located to second rubber circle 3, and another PVC pipe 1's diameter is less than the PVC pipe 1 of the former, makes two PVC pipe 1 like this be the telescopic machanism that the ring was buckled mutually, and this device simple structure makes to lengthen also simpler, and the collection of a section when not using is long into the whole longer pipeline of root length with the tube coupling of a section when using.

Drawings

Fig. 1 is a schematic structural diagram of the extendable PVC pipe of the present invention.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

In the figure 1, a PVC pipe 1, a first rubber ring 2 and a second rubber ring 3.

The utility model provides a can prolong type PVC pipe, can prolong type PVC pipe includes the at least two PVC pipe 1 of body, the inner wall of the one end of PVC pipe 1 is equipped with first rubber circle 2, the outer wall of the other end of PVC pipe 1 is equipped with second rubber circle 3, and the connected mode of first rubber circle 2, second rubber circle 3 and PVC pipe 1 is the powerful glue bonding. The first rubber ring 2 is buckled with the second rubber ring 3, as shown in fig. 1, the PVC pipe 1 is mutually sleeved and then stretched, when the PVC pipe is pulled to the positions of the first rubber ring 2 and the second rubber ring 3, because the first rubber ring 2 and the second rubber ring 3 are both in a taper sleeve-shaped structure, the PVC pipe 1 cannot be continuously pulled after being stretched, and the first rubber ring 2 and the second rubber ring 3 form mutual extrusion under the effect of taper under the condition of being pulled again, so that the two PVC pipes 1 are connected more tightly, and the principle of the PVC pipe cannot be easily retracted after being stretched by force is the same as that of a fishing rod. First rubber circle 2 locates the one end of PVC pipe 1, and second rubber circle 3 locates the one end of another PVC pipe 1, and the diameter of another PVC pipe 1 is less than former PVC pipe 1, makes two PVC pipes 1 can be the telescopic machanism that the ring is buckled mutually like the fishing rod like this, and this embodiment has three to connect, and under the state that many PVC pipes 1 elongated, first rubber circle 2 with second rubber circle 3 takes place the extrusion for leakproofness between the PVC pipe 1 becomes very good, and the pipeline of formation wholly can regard as the carrier of water. First rubber circle 2, second rubber circle 3 are taper sleeve shape structure, first rubber circle 2 is located the internal diameter of 1 outer mouthful of PVC pipe is less than PVC pipe 1 is kept away from the internal diameter of 1 outer mouthful of PVC pipe, second rubber circle 3 is located the external diameter of 1 outer mouthful of PVC pipe is greater than PVC pipe 1 keeps away from the external diameter of 1 outer mouthful of PVC pipe.
