Embodiments of the present invention are described below with reference to the accompanying drawings, in which:
fig. 1 is the utility model provides a position adjustable stainless steel package is moulded to package and is moulded the stereogram of hot-water line is moulded to the package.
Detailed Description
The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
Referring to fig. 1, the stainless steel plastic-covered hot water pipe with adjustable plastic-covered position provided by the present invention includes a stainless steel pipe 10 and a plastic cover 20 movably covering the stainless steel pipe 10.
The stainless steel pipe 10 is provided with an external thread 11 on the outer side wall in a protruding manner, and the plastic sleeve 20 is provided with an internal thread on the inner side wall. The internal thread of the plastic sleeve 20 is in threaded connection with the external thread 11 of the stainless steel pipe 10.
In this embodiment, the external threads 11 on the outer sidewall of the stainless steel tube 10 are thread segments arranged at intervals, so that the difficulty in manufacturing can be reduced.
The length of the plastic sleeve 20 is less than that of the stainless steel tube 10, and both ends of the stainless steel tube 10 protrude out of the plastic sleeve 20.
The outer side wall of the end part of the stainless steel pipe 10 is provided with a plurality of first clamping grooves 12 along the circumferential direction in a concave mode, and the outer side wall of the plastic sleeve 20 is provided with a plurality of second clamping grooves 21 along the circumferential direction in a concave mode.
In one embodiment, the number of the first clamping grooves 12 at any end of the stainless steel tube 10 is 2, and the first clamping grooves are arranged at two ends of the stainless steel tube 10 along the radial direction; the second engaging grooves 21 are disposed at two ends of the plastic sleeve 20 along the radial direction.
