Telescopic PE pipe

Abstract

The invention discloses a telescopic PE pipe which comprises a third PE pipe. Third PE pipe fastening screws are arranged on the outer circle wall of a third flange. The inner side of the third PE pipe is connected with a second PE pipe in a sleeving manner. Second PE pipe fastening screws are arranged on the outer circle wall of a second flange. The inner side of the second PE pipe is connected with a first PE pipe in a sleeving manner. First PE pipe fastening screws are arranged on the outer circle wall of a first flange. Flange fixing holes are formed in each of the first flange, the secondflange and the third flange. According to the telescopic PE pipe, the second PE pipe is connected to the interior of the third PE pipe in a sleeved manner, the first PE pipe is connected to the interior of the second PE pipe in a sleeved manner, the length of the part, stretching out of the third PE pipe, of the second PE pipe and the length of the part, stretching out of the second PE pipe, of the first PE pipe can be controlled through the third PE pipe fastening screws, the second PE pipe fastening screws and the first PE pipe fastening screws, and therefore the length of the whole PE pipecan be adjusted; and when not used, the whole PE pipe is shrunk to be shortest, and the whole PE pipe is convenient to carry at this moment.

Description

technical field [0001] The invention relates to a PE pipe, in particular to a stretchable PE pipe. Background technique [0002] Due to the comprehensive advantages of safety, sanitation, convenient construction and long service life, PE pipes are widely used in building water supply, building drainage, buried drainage pipes, building heating, gas pipelines, electrical and telecommunications protection casings, and industrial pipes. , Agricultural pipes and other fields. [0003] However, the length of PE pipes currently on the market cannot be adjusted during use. Since the distance between every two nozzles that need to be connected changes in production and life, if special treatment is made according to special circumstances, it is not only inconvenient to install. Moreover, it is time-consuming and labor-intensive, so if there is a stretchable PE pipe, that is, a PE pipe that can adjust the length, then the length of the PE pipe can be adjusted according to the distanc...

[0003] However, the length of PE pipes currently on the market cannot be adjusted during use. Since the distance between every two nozzles that need to be connected changes in production and life, if special treatment is made according to special circumstances, it is not only inconvenient to install. Moreover, it is time-consuming and labor-intensive, so if there is a stretchable PE pipe, that is, a PE pipe that can adjust the length, then the length of the PE pipe can be adjusted according to the distance between the two butt joints, so as to facilitate the installation of the PE pipe
