Description

TECHNICAL FIELD

[0001] The utility model relates to the field of pipe material, especially a PVC pipe material with end breakage prevention. BACKGROUND

[0002] PVC pipe material is a common plastic pipe material, which is widely used in pipeline systems in the fields of construction, industry, agriculture, etc.

[0003] When the PVC pipe material is used, two adjacent pipelines are usually connected by using a fixing part, or two adjacent pipelines are connected by using a hot melting device. However, after the pipelines are connected, the two ends of the connected pipelines are still in an open shape. Therefore, when the pipelines are used, the end of the pipeline at the opening will be torn and broken when it is pressed.

[0004] In order to improve the protection of the end of the pipeline at the opening, a metal protective sleeve is usually sleeved on the end of the pipeline at the opening to improve the strength of the end of the pipeline. When the metal protective sleeve is installed, it is usually fixed by using screws or adhesion. The use of screws will cause damage to the pipeline itself, and the use of adhesion will not facilitate the disassembly of the metal protective sleeve when the pipeline is connected again, thereby reducing the convenience of use.
