Abstract
The utility model discloses a thin-wall metal connection conveying pipe, the pipe body is a hollow metal pipe with certain extension, the external wall of the end part of the pipe body swells at least three sections of hollow projections, each section of projection is positioned on a same plane which is vertical to the central axial line of the pipe body, the design of the utility model increases the pipe end strength, greatly reduces the wall thickness of the pipe, and saves a great quantity of metal material; as the pipe is connected with a connecting piece, the end part of the pipe is not damaged, and the speed of the connection and the assembly is quick; the utility model has the advantages that the repeated assembly and disassembly are convenient, the firmness is good, and the tightness is good, etc.
Description
Technical field
The utility model relate to connect with or liquid, gas delivery with the field, particularly thin-wall metal tube of tubing.
Background technique
Metal pipe is stainless steel pipe particularly, in many-sided extensive uses such as water supply, heat supply, air feed, railing, guardrail, balustrades.And at present, most metal pipe often uses the hinge worm tooth of damage pipe end or is welded to connect method when connecting use, and the wall thickness of hinge worm tooth tubing need be reserved enough surpluses for the processing of tube wall, causes the metallic material waste.When employing was welded to connect method, the metal material alloying constituent was wandered away when welding temperature was too high, influenced tubing working life and cause easily to get rusty, and simultaneously, exists difficulty is installed, technical requirements height, shortcoming such as the construction environment narrow limitation is big.According to Chinese patent 03225536.5 " a kind of conveying connecting tube " employing is body end protuberance one circle bulge loop, the metal connecting tube structure has the wall thickness of minimizing and is connected easy advantage, but this mode is confined to circular pipe connects purposes, as square tubular, irregular tubing such as elliptical tube just is difficult to expand protuberance one circle bulge loop, so adopt the welding method that connects the technology relative complex when these tubing connect, this method difficulty of construction is big, installation rate causes engineering cost to increase slowly.
The model utility content
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, proposes a kind of being easy to and connects, and is connected firmly, the thin-wall metal of good seal performance connects delivery pipe during as conveying, fundamentally reduce the metallic material consumption of tubing, reduce production costs, lower the labor intensity that connects.
The purpose of this utility model is achieved by the following technical solution: thin-wall metal connects delivery pipe, body is the hollow metal tube with certain ductility, protuberance has at least three sections cannular boss, each section boss all to be on the same plane vertical with the body central axis on the outer wall of body end.Further, stressed evenly for making the connection sealing, equidistant between each section boss.For adapting to different connections, body is hollow circular pipe or hollow ellipse shape pipe.All right, adopting body is hollow many seamed edges pipe, and swelling at least on each faceted pebble has one section boss.The intensity that connects for guaranteeing, each section boss is contour, boss to the distance of body port smaller or equal to 50mm, and its aspect ratio tube wall exceeds smaller or equal to 3mm.
Such tubing, when being used for the output of liquid, gas, as long as fitted seal circle, packing ring, pipe cap can be directly and the pipe fitting of all size, lead directly to, threeway, four-way, elbow etc. are tightly connected securely.Need not carry out damaging processing or welding to the tubing end, need not twist worm tooth and reserve the cutting process surplus; As long as firmly is connected with pipe fitting with bore, have light weight when nonfluid carries tubing to connect, wall approaches the good airproof performance that is connected firmly, installation connection and dismantle advantages such as efficient and convenient.
Description of drawings
Fig. 1 is a schematic representation of the present utility model;
Fig. 2 is embodiment two a schematic representation;
Fig. 3 is the schematic representation of the utility model and pipe fitting assembling.
Embodiment
Referring to Fig. 1 and Fig. 3, present embodiment adopts stainless hollow circular pipe 1, near the radially pressurization respectively port of tubing 1, protuberance forms five sections separate boss 11, each boss 11 inner hollow and periphery and tubing 1 outer wall seamlessly transit, each section boss 11 all is on the same plane vertical with tubing 1 central axis, and the spacing between them equates.When tubing 1 and connection pipe fitting 2 assemblies are tightly connected (as shown in Figure 3), pipe cap 4 is packed in the tubing 1 dorsad, form each boss 11 in the pressurization of tubing 1 end pipe, rubber seal 3 is placed on the place ahead of boss 11, pipe end is inserted in the connection pipe fitting 2, pipe cap 4 spins with connection pipe fitting 2, so again, each section boss 11 withholds between seal ring 3, pipe cap 4, connection pipe fitting 2, fastening, formation is tightly connected.During actual the use, the distance between boss 11 and tubing 1 port is preferably in the 50mm scope, and the wall thickness of tubing 1 does not preferably exceed 3.5mm, and the height of boss 11 exceeds like body 1 outer wall and is no more than 3mm.
Embodiment two, referring to Fig. 2, in some specific use occasions, also can adopt polygon prismatic pipe such as square tubing 1 ', boss 11 ' totally four sections, take shape in respectively square pipe 1 ' four faceted pebbles on.In addition, at non-tight, when non-conveying connects, similar non-circular tubing also can be used as guardrail, railing, the isostructural simple connection of handrail.
Certainly, only enumerated two kinds of preferred implementation here, the protection category that other is equal to, structure roughly the same all should belong to this patent repeats no more here.
Claims (5)
1. thin-wall metal connects delivery pipe, and body is the hollow metal tube with certain ductility, it is characterized in that: protuberance has at least three sections cannular boss, each section boss all to be on the same plane vertical with the body central axis on the outer wall of body end.
2. connection delivery pipe according to claim 1 is characterized in that between each section boss equidistant.
3. connection delivery pipe according to claim 1 and 2 is characterized in that body is hollow circular pipe or hollow ellipse shape pipe.
4. connection delivery pipe according to claim 1 and 2 is characterized in that body is hollow many seamed edges pipe, and swelling at least on each faceted pebble has one section boss.
5. connection delivery pipe according to claim 1 and 2 is characterized in that each section boss is contour, boss to the distance of body port smaller or equal to 50mm, and its aspect ratio tube wall exceeds smaller or equal to 3mm.
