Abstract
The utility model discloses a plastic-aluminum double-layer composite transport connecting pipe. A main body is a hollow pipe body, at least the outer wall of which is made of plastic; the plastic outer wall at the end part of the pipe body is sleeved with a section of aluminium alloy case pipe with ductility; a circle of channel is formed on the aluminium alloy case pipe after the case pipe is rolled and extruded, which is used for preventing the aluminium alloy case pipe from falling off from the pipe body. The design greatly improves the connecting strengthen at the position of the end port of the plastic pipe body, the attended operation can be operated easily, and the connecting pipe can be assembled and disassembled over and over and the sealing performance will not be affected, thus not only relieving the labor intensity, but also decreasing the manufacturing and construction cost, thereby the plastic pipe has a wider application prospect.
Description
Technical field
The utility model relates to the tubing field, particularly aluminium-plastic composite pipe that FLUID TRANSPORTATION is used.
Background technique
Traditional plastic tube, aluminium-plastic composite pipe, steel-plastic composite pipe are owing to the characteristic of plastic material limits, can not as metal, direct installation connect and can install and remove repeatedly, be merely able to adopt the way of damage pipe end to carry out the installation connection of pipe fitting, adopt hot melt to be tightly connected as plastics PPR pipe, because the plastics pipe end needs through heating once more, become regenerated plastics, shortened the working life of pipe end connection part greatly.And the Placement of aluminium-plastic composite pipe seals in generally adopting, and promptly the internal diameter at aluminium-plastic composite pipe injects the copper core pipe of being with seal ring, presses to form at the body wild card of aluminium-plastic composite pipe then to be tightly connected.It installs connection can only be disposable, and pipe end cancels as if reconnecting then, and shortcoming is repeated multiple times to install and remove, and makes troubles for the construction connection of reality.
The model utility content
The purpose of this utility model is the deficiency that overcomes conventional plastic material tubing, proposes a kind of plastic-aluminum two-layer compound that is easy to install and remove connection, is tightly connected firmly and does not damage the body port and carries connecting tube.Make body repeatedly install and remove connection repeatedly, can adapt to on-site construction operations, alleviate the labor intensity that construction connects.
The purpose of this utility model is achieved by the following technical solution: a kind of plastic-aluminum two-layer compound is carried connecting tube, main body is that outer wall is the hollow body of plastic material at least, cover is inserted with one section aluminum alloy sleeve pipe that is ductile on the plastics outer wall of body end, is formed with a circle groove that prevents that it from getting loose from body through roll extrusion, extruding on the aluminum alloy sleeve pipe.Further, hollow body is aluminium-plastic composite pipe, steel-plastic composite pipe or all-plastic pipe.In order not damage body, keep the original-shape of inboard wall of tube body, hollow body only be formed with on the plastic layer of outer wall with the aluminum alloy sleeve pipe on the corresponding shallow grooves of a circle groove.For the intensity of protection body port and be easy to the execute-in-place construction, the circle of one on aluminum alloy sleeve pipe groove is that the aluminum alloy sleeve pipe box inserts in behind the hollow tubular end of body by the distortion of extending of roller lateral extrusion and forms.
Such structure has tangible advantage:
1, be seated the aluminum alloy sleeve pipe that connects by cover, make plastic material body pipe end radially compressive resistance, stretching resistance improve greatly, and do not damage tube end, be easy to mounting or dismounting and connect;
2, the aluminum alloy sleeve pipe forms closely with the plastic tube body outer wall by the groove that encircles into a circle that face contacts, even there is bigger pressure also to be difficult for getting loose in the body;
Use but 3, make plastic tube body become the repeated multiple times mounting or dismounting, widened the application of plastic tube body greatly by traditional disposable installation;
4, by the aluminum alloy sleeve pipe, it is very easy that the construction of the body of plastic material is connected, and need not heat, and can directly be connected with other pipe fitting, greatly reduces the labor intensity of construction, reduced construction cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, present embodiment mainly is made of hollow body 1 of all-plastic and aluminum alloy sleeve pipe 2, aluminum alloy sleeve pipe 2 only is a section of finite length, its internal diameter just closes with the external diameter cover inserting of hollow body 1, and mainly be the end that cover inserts in hollow body 1, it all is all level and smooth inside and outside the tube wall that cover is inserted the above two, after aluminum alloy sleeve pipe 2 covers insert on the hollow body 1, with roller in the roll extrusion of radially exerting pressure of the outer wall of aluminum alloy sleeve pipe 2, aluminum alloy sleeve pipe 2 is extended to be out of shape, form the groove 21 of the annular indent of a circle, because plastic hollow body 1 is subjected to roller extruding with aluminum alloy sleeve pipe 2, correspondingly, the extruding that the outer wall of plastic hollow body 1 is subjected to groove 21 is local deformation also, form shallow grooves 11 with groove 21 corresponding matching, the inwall of hollow body 1 then keeps level and smooth original state, like this, just forms the surface of contact of a circle arc between aluminum alloy sleeve pipe 2 and the plastic hollow body 1, thereby increased connection power and bearing strength between the two greatly, made the end rigidity intensity of plastic hollow body 1 better.
In addition to the implementation; hollow body also can adopt steel-plastic composite pipe or aluminium-plastic composite pipe; as long as outer wall is a plastic material; and metal sleeve can adopt other ductility preferred metal materials such as copper, aluminium; in sum; with the protection category that aforementionedly is equal to, roughly the same structure all should belong to this patent, repeat no more.
Claims (4)
1, a kind of plastic-aluminum two-layer compound is carried connecting tube, main body is that outer wall is the hollow body of plastic material at least, it is characterized in that: cover is inserted with one section aluminum alloy sleeve pipe that is ductile on the plastics outer wall of body end, is formed with a circle groove that prevents that it from getting loose from body through roll extrusion, extruding on the thin-wall metal sleeve pipe.
2, conveying connecting tube according to claim 1, it is characterized in that hollow body only be formed with on the plastic layer of outer wall with the aluminum alloy sleeve pipe on a circle groove corresponding shallow grooves.
3, conveying connecting tube according to claim 1 and 2, it is characterized in that hollow body only be formed with on the plastic layer of outer wall with the aluminum alloy sleeve pipe on a circle groove corresponding shallow grooves.
4, conveying connecting tube according to claim 1 and 2 is characterized in that the circle of one on aluminum alloy sleeve pipe groove is to be formed by roller lateral extrusion extension distortion after the aluminum alloy sleeve pipe box inserts in the hollow tubular end of body.
