Rack type joint of hose

Abstract

The invention discloses a rack type joint of a hose. The rack type joint comprises a joint pipe body and two nut sleeves, casing transition segments are arranged at the two ends of the joint pipe body, two near ends, close to the casing transition segments, of a middle pipe body are each fixedly connected with a fixing sleeve, through holes are axially, annularly and evenly distributed on in the side walls of the fixing sleeves, two movable sleeves are arranged between the two fixing sleeves, each movable sleeve comprises a rack segment and a thread segment, each rack segment comprises multiple annular evenly-distributed racks, the racks, on the same side, of the movable sleeves are correspondingly inserted in the through holes of the fixing sleeves, the inner circumference face of each thread segment is at least provided with an axial guide groove, a guide convex edge is arranged on the outer wall of the middle pipe body, an outer thread is arranged on the outer circumference face ofeach thread segment, each nut sleeve comprises a conical face and an inner thread face, and the outer threads of the thread segments are matched with the inner threads on the inner thread faces of thenut sleeves. Compared with the prior art, the rack type joint has the beneficial effects of being convenient to mount and dismount, easy and convenient to operate, labor-saving, not prone to leakageand more not prone to falling off.

Description

Technical field [0001] The invention relates to a rack joint of a hose. Background technique [0002] At the production site of enterprises, there are often equipment that uses gas or liquid working medium. The medium conveying pipeline uses hoses. The connection and use of various high and low pressure hoses is a relatively common phenomenon, especially oxygen, This is especially true for thermal processing units where fuel gas, compressed air and nitrogen, hydrogen, argon, and carbon dioxide gas are working media. The connection method of the hose is generally connected by wire binding or pipe clamp (including extruded pipe clamp and screw tension pipe clamp). The common feature of these three connection methods is that the bundled or clamped hose is produced The inward compression deformation is realized by the friction resistance between the inner surface of the hose or the inner surface of the inner tube and the outer surface of the connecting tube core (inverted cone pipe ...

Problems solved by technology

[0005] But its disadvantage is that it is divided into three parts, which need to be matched with each other in size, and the processing process is cumbersome.

[0007] Its disadvantage is that the structure is too complex
