Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipes. Background Art

[0002] The plastic tube comprises a plastic tube body, which is generally a single-layer structure and has the disadvantage of poor thermal insulation effect. The double-layer plastic tube comprises an inner tube and an outer tube. In the prior art, the outer surface of the inner tube and the inner surface of the outer tube are bonded together, which still has the disadvantage of poor thermal insulation effect. In addition, the plastic tube in the prior art also has the disadvantage of poor antibacterial effect. Summary of the invention

[0003] The utility model aims to provide a plastic pipe with good heat preservation effect and good antibacterial effect, that is, an antibacterial heat-insulating plastic pipe, in view of the above-mentioned shortcomings.

[0004] The technical solution of the utility model is implemented as follows: an antibacterial heat-insulating plastic pipe includes a plastic pipe body, wherein the plastic pipe body includes an inner tube and an outer tube, and is characterized in that: the inner tube and the outer tube are connected by a plurality of connectors, and there are gaps between the plurality of connectors.

[0005] Furthermore, there is a zinc-based alloy layer inside the inner tube.

[0006] Furthermore, the gap is filled with rock wool.

[0007] Furthermore, one end of the plastic pipe body also has an expanded diameter portion, the inner diameter of the expanded diameter portion is equal to the outer diameter of other parts of the plastic pipe body, and the outside of the expanded diameter portion is provided with a metal hoop.

[0008] Furthermore, the inner tube also has a plurality of evenly distributed first steel wires arranged along its length direction.

[0009] Furthermore, the outer tube also has a plurality of evenly distributed second steel wires arranged along its length direction.

[0010] The beneficial effects of the utility model are as follows: the plastic pipe has the advantages of good heat preservation effect and good antibacterial effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Among them: 1, inner tube 2, outer tube 3, connector 4, gap 5, zinc-based alloy layer 6, rock wool 7, expanded diameter part 8, metal hoop 9, second steel wire 10, first steel wire. DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings.

[0016] like Figure 1 , 2 As shown in FIG. 3 , an antibacterial heat-insulating plastic pipe comprises a plastic pipe body, wherein the plastic pipe body comprises an inner layer pipe 1 and an outer layer pipe 2, and is characterized in that: the inner layer pipe and the outer layer pipe are connected by a plurality of connectors 3, and there are gaps 4 between the plurality of connectors.

[0017] Since the gap is arranged in the middle of the plastic pipe body, the utility model can have a certain heat storage function and achieve the purpose of the utility model.

[0018] Furthermore, there is a zinc-based alloy layer 5 inside the inner tube.

[0019] The zinc-based alloy layer of the utility model has a good anti-corrosion effect, the surface of the zinc-based alloy layer is smooth and not easy to breed algae, and a good antibacterial effect can be achieved.

[0020] Furthermore, the gap is filled with rock wool 6.

[0021] The utility model is arranged in this way, and has a better heat preservation effect.

[0022] Furthermore, one end of the plastic pipe body is provided with an enlarged diameter portion 7, the inner diameter of the enlarged diameter portion is equal to the outer diameter of other parts of the plastic pipe body, and a metal hoop 8 is provided outside the enlarged diameter portion.

[0023] The utility model is arranged in this way, so as to prevent the connection part from cracking.

[0024] Furthermore, the inner tube also has a plurality of evenly distributed first steel wires 10 arranged along its length direction.

[0025] Furthermore, the outer tube also has a plurality of evenly distributed second steel wires 9 arranged along its length direction.

[0026] The utility model is arranged in this way, and has a better tensile resistance effect.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the specification of the present invention.
