Description

Technical Field

[0002] Stainless steel corrugated hose is a flexible industrial metal material with good temperature and pressure resistance. It is classified by use: mainly including metal bellows, corrugated expansion joints, corrugated heat exchange tubes, diaphragm boxes, etc. Metal bellows are made of thin-walled stainless steel welded pipes through corrugated processing. They are flexible and have good temperature and pressure resistance. They are suitable for the transportation of various fluid media such as air, steam, various industrial gases, water, oils, and medicines. It plays an important role in the reciprocating motion of the pipe system, absorption of thermal expansion system, vibration absorption, and center adjustment of the piping. According to the different classifications of the bellows, there are mainly two types, one is annular corrugated hose, and the other is spiral bellows.

[0003] After searching, an insulated stainless steel corrugated hose with a publication number of CN219242989U specifically discloses an insulated stainless steel corrugated hose, including a connecting pipe, an insulating sheet is provided on the inner wall of the connecting pipe, a bellows is provided on the outer wall of the connecting pipe, connecting heads are provided on two opposite side walls of the bellows, limiting sheets are provided on two opposite side walls of the bellows, and a protective component for reducing the probability of scalding is provided on the bellows. The present application has the effect of reducing the probability of scalding of staff.

[0004] The above patent only achieves the effect of reducing the probability of workers being scalded by connecting pipes, insulating sheets, bellows, connectors, limit sheets and protective components. However, during the use of the stainless steel corrugated hose, due to the different ways of using the stainless steel corrugated hose, when the stainless steel corrugated hose is pulled, it only relies on the threaded connection between the screw mouth and the screw tube to allow the stainless steel corrugated hose to resist the pulling force, which cannot fully protect the normal use of the stainless steel corrugated hose. Due to the mutual pulling, the screw mouth of the stainless steel corrugated hose will slip, causing the pipe connected to the stainless steel corrugated hose or the stainless steel corrugated hose and the screw mouth to fall off. This is not convenient for the stainless steel corrugated hose to be used for the transportation of liquids or gases, and is likely to cause safety hazards.

[0005] Therefore, it is necessary to invent a kind of anti-slip stainless steel corrugated hose to solve the above problems. Utility Model Content
