Description

Technical Field

[0001] The invention relates to the technical field of water pipes, in particular to a reinforced stainless steel water pipe. Background Art

[0002] Stainless steel water pipes are the best pipes for direct drinking water transportation. They have a very low leakage rate and can save precious water resources. The leakage rate of water pipes in the 1980s was about 17%, but after switching to stainless steel water pipes, the leakage rate dropped to 7%;

[0003] When stainless steel pipes are in use, due to their long length, they are easily bumped and deformed during installation, changing their shape. During long-term use, the pressure bearing capacity of different parts of the pipes is different, which can easily cause damage and reduce their service life. When stainless steel water pipes are bent by pipe bending machines, the bending parts are easily damaged, which can easily cause cracking and damage to the water pipes. Summary of the invention

[0004] The purpose of the present invention is to provide a reinforced stainless steel water pipe, which solves the technical problems that the pipe is easily deformed and deformed during installation, changing the shape of the pipe, and the pressure bearing capacity of different parts of the pipe is different during long-term use, which easily causes damage.

[0007] The support assembly includes a limiting ring, a roller, a support frame, a slide groove, fan blades and a central shaft seat. The inner wall of the tube body is fixedly connected to the limiting ring, and the inner side of the limiting ring is surrounded by a slide groove. A plurality of support frames are fixedly connected to the circumferential surface of the central shaft seat in an annular matrix. The end of the support frame is equipped with a roller through a pin shaft, and a plurality of fan blades are fixedly connected to the circumferential surface of the central shaft seat in an annular matrix.

[0008] As a further solution of the present invention: the central axis of the limiting ring is in the same straight line with the central axis of the tube body, and the central axis of the central axis seat is in the same straight line with the central axis of the limiting ring.

[0009] As a further solution of the present invention: three rollers are arranged in a ring matrix on the circumferential surface of the central shaft seat, and the rollers are engaged and snap-fitted in the sliding grooves.

[0010] As a further solution of the present invention: the thickening component includes a positioning ring, a folding sleeve, a positioning pin, an expansion spring and a rubber pad, the folding sleeve is sleeved on the outside of the tube body, and positioning rings are respectively fixed at both ends of the folding sleeve. Positioning screw holes are arranged in a circular matrix on the positioning ring, and a plurality of positioning pins are passed through the positioning ring in a circular matrix.

[0011] As a further solution of the present invention: an expansion spring is sleeved on the positioning pin, a rubber pad is packaged at the end of the positioning screw hole, and the surface of the rubber pad is in contact with the end face of the positioning pin.

[0012] As a further solution of the present invention: the inner wall of the positioning ring is in contact with the outer side of the tube body, and the central axis of the positioning pin is perpendicular to the central axis of the tube body.

[0013] The beneficial effects of the present invention are as follows: by setting a support assembly, a support frame is installed on the outside of the central shaft seat, and with the cooperation of the roller, the pipe body can be supported, the strength of the pipe body can be enhanced, and the deformation of the pipe body can be reduced. During the flow of water, with the cooperation of the fan blades, the roller slides along the slide groove, driving the central shaft seat to rotate, thereby achieving a better support effect, improving the strength of the water pipe, not easily deformed, and being able to be used for a long time.

[0014] By setting the thickening component, during the pipe bending operation, the folding sleeve between the two positioning rings is slid to the bending position, the two positioning rings are positioned, and after positioning, the water pipe is bent. After bending, the folding sleeve is wrapped around the outside of the pipe body, which can increase the wall thickness at the complete position and prevent the pipe body from cracking and leaking, making it safer to use and more stable in the pipe bending operation.
