Abstract
The utility model relates to a corrugated pipe consisting of an internal composite plastic layer D-shaped framework and the corrugated pipe can effectively improve the strength of the large-caliber corrugated pipe and fundamentally improve elasticity of the large-caliber corrugated pipe and comprises an inner pipe. The cross section of the metal pipe enlacing the inner pope body is a D-shaped structure of an opening at the bottom and the bottom of the D-shaped metal pipe which has openings is compounded with the inner pipe body. Plastic on the pipe body is embedded in the openings at the bottom of the D-shaped metal pipe. The plastic layer is compounded on the surface of the D-shaped metal pipe. The corrugated pipe has the advantages that by means of the surface contact of the D-shaped metal pipe bottom with the inner pipe surface, pressure on the inner pipe is greatly mitigated and support intensity and loading capacity of the inner pipe are greatly improved when the D-shaped metal pipe is pressed and straight and long through holes embedded with plastic wedges are arranged at the bottom of the D-shaped metal pipe, thereby ensuring reliable compound of the D-shaped metal pipe with the inner pipe wall.
Description
Technical field
The utility model relates to a kind ofly can not only improve heavy caliber bellows intensity effectively, and the bellows that is made up of interior multiple plastic layer D shape skeleton that can make that the elasticity of heavy caliber bellows obtains that essence improves, and belongs to bellows and makes the field.
Background technique
CN201078525Y, title " socket joint electric smelting jointing type steel band reinforced polyethylene spiral ripple pipe ", it is used to solve the problem of easy seepage of steel band reinforced polyethylene spiral ripple pipe connection interface and poor reliability.Socket joint electric smelting jointing type steel band reinforced polyethylene spiral ripple pipe; Be the metal frame that twines to be fixed on the inner layer polyethylene with outer layer polyethylene; Particularly an end of bellows is provided with socket, and the other end of bellows is provided with bellmouth, imbeds a circle electric heating element on the bellmouth inwall and forms.Adopt this socket joint electric smelting jointing type steel band reinforced polyethylene spiral ripple pipe, can be widely used in the connection construction of plastic tube.Its deficiency: the one, metal frame is the outer structure of taking off, and what form with inner layer polyethylene is that the line face contact, rather than face contacts; Not only plyability is poor; And under the effect of external force, metal frame is prone to take off mobile outward, causes inner layer polyethylene is destroyed; The quality of direct shadow pipe matter, even cause inner layer polyethylene damaged; The 2nd, support strength is low, because metal frame is the outer structure of taking off, outwards move its metal frame both sides of external pressure, not only causes the layering of metal frame and inner layer polyethylene, and cause the direct reduction of inner layer polyethylene intensity; The 3rd, because outer layer polyethylene and metal frame are two kinds of material different, had nothing in common with each other by its coefficient that expands with heat and contract with cold of Influence of Temperature, therefore stratification in use takes place inevitably, cause bellows intensity sharply to descend, bellows caves in.
The model utility content
Purpose of design: avoid the deficiency in the background technique, design a kind of heavy caliber bellows that can not only improve effectively and strengthen, and can make the elasticity of heavy caliber bellows obtain a kind of bellows that constitutes by interior multiple plastic layer D shape skeleton that essence improves.
Design proposal: in order to realize above-mentioned purpose of design.The metal tube cross section is the design of D shape, is the major technique characteristic of the utility model.The purpose of doing like this is: because D shape metal tube bottom surface opening is to open along D shape metal pipe range; Be along long through-hole, supported on both sides limit in the middle of the formed pipe bottom surface; And along long through hole with interior pipe compound tense, be used to make molten plastic on the inner tubal wall get into along in the long through-hole and with form snap fit along long through-hole, both played the effect that move spacing support edge; Play the rivet effect of riveted joint D shape metal tube again, played the effect of pipe intensity in strengthening simultaneously again; Secondly, D shape metal tube is when receiving the external force extruding, and D shape metal tube is neither outwards taken off and moved, and also can inwardly not contract and move, and has guaranteed reliably compound between D shape metal tube and inner tubal wall.
Technological scheme 1: a kind of bellows that constitutes by interior multiple plastic layer D shape skeleton; It comprises interior pipe; It is mutually compound with the pipe shaft of interior pipe that the metal tube cross section of pipe on the pipe shaft is the bottom surface of D shape metal tube of D shape structure and bottom surface opening of bottom surface opening in being wrapped in; Plastics on the pipe shaft embed in the opening of D shape metal tube bottom surface, and plastic layer is compounded on the D shape inner wall of metal tube.
The utility model is compared with background technique, and the one, D shape metal tube bottom surface contacts with the inner tube surface face, when making D shape metal tube pressurized, has greatly alleviated the pressure of internal pipe, and D shape metal tube is just as the arch bridge structure, and bearing capacity is big; The 2nd, because D shape metal tube bottom surface contacts with the inner tube surface face, greatly improved interior pipe support strength and bearing capacity; The 3rd, because D shape metal tube bottom surface has through hole to be embedded with the plastics wedge along having grown, guaranteed reliably compound between D shape metal tube and inner tubal wall.

Fig. 2 is the cross section structure schematic representation of D shape metal tube among Fig. 1.
Embodiment
Embodiment 1: with reference to accompanying drawing 1-2.A kind of bellows that constitutes by interior multiple plastic layer D shape skeleton; Pipe 1 in it comprises; It is mutually compound with the pipe shaft of interior pipe 1 that metal tube 2 cross sections of pipe on 1 pipe shaft are the bottom surface of D shape metal tube of D shape structure and bottom surface opening of bottom surface opening in being wrapped in; Plastics on the pipe shaft embed in the D shape metal tube 2 bottom surface openings, and plastic layer 3 is compounded in (inner tube wall that is D shape metal tube 2 has plastic layer 3 again) on D shape metal tube 2 inwalls.It is little 20 millimeters that said D shape metal tube 2 bottom surfaces are A/F.Said opening is meant D shape metal tube length direction opening 4.Said D shape metal tube 2 adopts steel band to make.Its making method: adopt the metal tube producer that steel band is processed the bottom and be the semicircle D shape metal tube of plane of the opening; Adopt the heavy caliber polyolefin winding growth pipe production line of claimant's manufacturing in making bellows, to manage in 1 process then; While make pipe in the bellows, with semicircle D shape pipe be wrapped on the bellows and the ripple tube wall on plastics embed in the opening of semicircle D shape pipe, adopt the heavy caliber polyolefin of claimant's manufacturing to twine at last to increase and manage production line molten plastic is compounded on the semicircle D shape inner tube wall.
What need understand is: the detailed text description though above-mentioned mentality of designing to the utility model is contrasted; But these text descriptions; Just the simple text of the utility model mentality of designing is described, rather than to the restriction of the utility model mentality of designing, any combination that does not exceed the utility model mentality of designing; Increase and modification, all fall in the protection domain of the utility model.
