Telescopic copper pipe component

Abstract

The invention discloses a telescopic copper pipe component which comprises an inner pipe and an outer sleeve. The outer sleeve is sleeved on the inner pipe. A inner pipe through hole is formed in the center of the inner pipe. A plurality of linear grooves parallel with the central line of the inner tube are evenly distributed on the outer periphery of the inner pipe. Protrusions are disposed on the inner wall of the inner hole of the outer sleeve. The protrusions are disposed in the grooves. By the structure, when the outer sleeve is sleeved on the inner pipe, the protrusions can move linearly along the grooves, and the outer sleeve can move along the inner pipe. In addition, annular grooves are evenly formed in the outer periphery of the inner pipe, and the central line of each annular groove coincides with that of the inner pipe. When the protrusions enter the annular grooves, the outer sleeve can be relatively locked with the inner pipe by rotating the outer sleeve. The telescopic copper pipe is simple in structure and practical.

Description

technical field [0001] The invention relates to an improvement of a copper pipe, in particular to a telescopic copper pipe assembly with simple structure and practicality, the outer sleeve can move linearly along the inner pipe and can be locked. Background technique [0002] The retractable copper tube usually includes an inner tube and an outer tube; the outer tube can move linearly along the outer circumference of the inner tube to realize the telescopic function, and finally reach the length required for the use of the retractable copper tube; in the prior art The structure of the retractable copper tube is relatively complicated, and the cost of production and use is high; therefore, we have developed a simple and practical structure, and the outer sleeve can move linearly along the inner tube and can be locked. Contents of the invention [0003] In view of the above technical problems, the object of the present invention is to propose a telescopic copper tube assembl...
