Abstract
The invention discloses a plastic tube, which comprises an outer tube and a nontoxic flexible inner tube; the inner hole wall of the outer tube is provided with a groove, and the groove is spirally formed; the periphery of the nontoxic flexible inner tube is provided with a protrusion matched with the groove on the inner hole wall of the outer tube; the nontoxic flexible inner tube is screwed into an inner hole of the outer tube, so that the corresponding protrusion is matched with the groove and the nontoxic flexible inner tube is fixed in the inner hole of the outer tube; the nontoxic flexible inner tube is made of polyethylene (PE) or polypropylene (PP); and the plastic tube is easily connected and has no toxicity when being used as a water delivery tube.
Description
Technical field
The present invention relates to a kind of plastic cement pipe, particularly a kind of avirulent plastic cement pipe belongs to the plasthetics technical field.
Background technique
The existing conduit pipe that is used to food or potable water, the material that it adopted has PE (polyethylene), PP (polypropylene) or PVC (PVC) plastic cement pipe, but there is not pore when pure PE, PP plastic cement Guan Yinqi moulding, therefore can't make it become a disjunctor with the sleeve pipe gummed between the pipe in twos, quite inconvenient, be an avirulent material but its maximum benefit is it.Moreover, as PVC plastic cement pipe, when being used in indoor decoration or water power pipe arrangement traditionally, for being fit to the variation of landform or region, can make it softening by fiery bake mode, and when it is still unhardened, can be easily with root in twos with material pvc pipe gluing fit to finish piping work, but the water pipe of general potable water is if adopt above-mentioned fit mode, because pvc pipe is through this processing or meet and can decomposite fatal toxin, the poison-dioxin in century when hot, so will produce greatest injury to human body, but convenient because of its pipe arrangement, it can't be abandoned sometimes need not at all.The inventor independently uses the disappearance of making for improving above-mentioned two materials, and thinks to add improvement, and the present invention is PE or PP material for the tool internal layer, and skin is the plastic cement pipe of PVC material, and making its part that contacts with potable water is non-toxic material, takes over but be easy to gummed.
Summary of the invention
Technical problem at above-mentioned existence the objective of the invention is: proposed a kind of avirulent, but be easy to glue together the plastic cement pipe of adapter.
Technical solution of the present invention is achieved in that a kind of plastic cement pipe, comprises outer tube, the soft interior pipe of avirulent; The inner hole wall of described outer tube is provided with groove, and described groove spirality is provided with; The excircle of pipe was provided with the projection of the groove fit on the inner hole wall with outer tube in described avirulent was soft; Make corresponding projection and groove fit in the endoporus of pipe precession outer tube in described avirulent is soft, thereby the soft interior pipe of avirulent is fixed in the endoporus of outer tube.
Preferably, the soft interior pipe of described avirulent is made by PE or PP material.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
The present invention adopts outer tube to make for the PVC material and interior pipe is the soft interior pipe that PE or PP make, can be by the material of PVC to carry out the adapter work between tube and tube, but adopt avirulent interior pipe, can make when being applied to conduit pipe its Security better, and sizable otherness is arranged with the plastic cement pipe of the unisexuality material of commonly using, and when being applied to the pipe arrangement in frigid zone or the frequent area of earthquake as if quilt, the Yin Qinei pipe is the PE material of software, split or when making outer tracheal rupture because of colder becoming fragile with the PVC material of outer tube even if be because of earthquake, its interior pipe also is difficult for breaking and the water of water pipe is leaked outside, thereby makes the present invention more meet initiative and practicability.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the stereogram of plastic cement pipe of the present invention;
Accompanying drawing 2 is the exploded view of plastic cement pipe of the present invention;
Wherein: 1, the soft interior pipe of avirulent; 2, outer tube; 3, projection; 4, groove.
Embodiment
Be depicted as a kind of plastic cement pipe of the present invention as accompanying drawing 1,2, comprise outer tube 2, the soft interior pipe 1 of avirulent; The inner hole wall of described outer tube is provided with groove 4, described groove 4 spirality settings; Pipe 1 excircle was provided with the projection 3 of the groove fit on the inner hole wall with outer tube in described avirulent was soft; In the endoporus of pipe 1 precession outer tube 2 corresponding projection 3 is cooperated with groove 4 in described avirulent is soft, thereby the soft interior pipe 1 of avirulent is fixed in the endoporus of outer tube 2; Pipe 1 was made by PE or PP material in described avirulent was soft.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
The present invention adopts outer tube to make for the PVC material and interior pipe is the soft interior pipe that PE or PP make, can be by the material of PVC to carry out the adapter work between tube and tube, but adopt avirulent interior pipe, can make when being applied to conduit pipe its Security better, and sizable otherness is arranged with the plastic cement pipe of the unisexuality material of commonly using, and when being applied to the pipe arrangement in frigid zone or the frequent area of earthquake as if quilt, the Yin Qinei pipe is the PE material of software, split or when making outer tracheal rupture because of colder becoming fragile with the PVC material of outer tube even if be because of earthquake, its interior pipe also is difficult for breaking and the water of water pipe is leaked outside, thereby makes the present invention more meet initiative and practicability.
The foregoing description only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (2)
1. a plastic cement pipe comprises outer tube, the soft interior pipe of avirulent; It is characterized in that: the inner hole wall of described outer tube is provided with groove, and described groove spirality is provided with; The excircle of pipe was provided with the projection of the groove fit on the inner hole wall with outer tube in described avirulent was soft; Make corresponding projection and groove fit in the endoporus of pipe precession outer tube in described avirulent is soft, thereby the soft interior pipe of avirulent is fixed in the endoporus of outer tube.
2. according to the plastic cement pipe of claim 1, it is characterized in that: pipe was made by PE or PP material in described avirulent was soft.
