The existing connecting pipe fitting can realize the connection operation of the water pipe so as to ensure that the water pipe can normally supply water. However, in the actual operation process, the following defects exist, because the existing water pipe is generally arranged in narrow or remote corners and other areas, and because the straight pipe fitting can not be bent at will, the replacement operation of a maintainer is inconvenient, the installation difficulty is high, and the quick and convenient replacement operation is difficult to realize; the length of the straight pipe fitting cannot be stretched, so that after the pipe section at the damaged part or the leakage part is cut off, the length of the required straight pipe fitting cannot be too short or too long, the replacement operation is high in professional, and popularization and use of installation and replacement operations of non-professional personnel (such as non-professional family members) are difficult to achieve.
SUMMERY OF THE UTILITY MODEL
The utility model provides a convenient connection pipe fitting is changed in pipeline usefulness and installation, its main aim at overcome current connection pipe fitting structural design ideal inadequately, can not realize quick convenient change and be difficult to realize shortcoming such as using widely of non-professional personnel installation change operation.
In order to solve the problem, the utility model adopts the following technical scheme:
a connecting pipe fitting for a pipeline and convenient to install and replace comprises a metal telescopic pipe, and a left plastic joint and a right plastic joint which are respectively connected to the left end part and the right end part of the metal telescopic pipe.
Furthermore, the metal telescopic pipe, the left plastic joint and the right plastic joint are formed in one step through injection molding.
Furthermore, the left and right plastic joints are plastic quick joints communicated with the pipeline in a hot melting mode.
Furthermore, the left and right plastic joints are plastic quick joints communicated with the pipeline in a gluing mode.
Further, the metal telescopic pipe is a stainless steel telescopic pipe; and the left plastic joint and the right plastic joint are both PVC quick joints.
Further, the metal telescopic pipe is formed with the left plastic joint and the right plastic joint on the outer side walls of the left end and the right end of the metal telescopic pipe respectively in an injection molding mode through an injection molding machine.
From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: this connecting pipe structural design ideal adopts the design that the metal expansion pipe combines left and right plastic joint for when this product can be buckled by arbitrary angle and tensile operation, can be linked together with current plastics water pipe with hot melt or rubber coating mode again, change convenient operation, the installation degree of difficulty is little moreover, can realize quick convenient change operation, especially is in the plastics water pipe change operation in comparatively narrow space or regions such as remote corner. And if the distance between the upper connecting point and the lower connecting point is slightly larger or smaller after the pipe section at the damaged part or the leakage part is cut off, the distance can be adjusted by stretching or contracting the metal telescopic pipe without worrying about the problems that the product is not installed and the like, the professional degree during installation is greatly reduced, and the popularization and the use of installation and replacement operations of non-professional personnel (such as non-professional family members) can be realized.

Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
Example one
Reference is made to figures 1, 2 and 3. A connecting pipe fitting for a pipeline and convenient to install and replace comprises a metal telescopic pipe 1, and a left plastic joint 2 and a right plastic joint 3 which are respectively connected to the left end part and the right end part of the metal telescopic pipe 1. The metal extension tube 1, the left plastic joint 2 and the right plastic joint 3 are formed in one step by injection molding. When the pressure-bearing pipeline (such as a plastic water pipe) is used, the left and right plastic joints 2 and 3 are plastic quick joints which are communicated with the pipeline in a hot melting or gluing mode. Adopt flexible pipe 1 of metal to combine the design of left and right plastic joint 2, 3 for when this connecting pipe fitting can be buckled by arbitrary angle and tensile operation, can be linked together with current plastics water pipe with hot melt or rubber coating mode again, change convenient operation, the installation degree of difficulty is little moreover, can realize quick convenient change operation, especially be in the plastics water pipe change operation in areas such as comparatively narrow space or remote corner.
