Abstract
The utility model discloses a thermal insulation drain of air conditioner and comprises an outer protective layer, insulating layers and inner tube, wherein the outer protective layer is arranged outside the insulating layer, an insulation layer is arranged between the insulating layers, the insulation layer inside the insulation layer is provided with the inner tube, and a capacity cavity is arranged on the inner tube, inside which a strengthening rib is arranged. As the structure above is used in the utility model, the utility model is provided with good insulation effect, the insulating layers are the double-layer structure and the two layers have an independent structure and do not affect each other, and the insulation effect is not only increased but also a solid structure is provided and does not easily fault; the overall spiral strengthening ribs are arranged on the inner layer of the drain so that the drain is more solid and has other advantages.
Description
Technical field
The utility model relates to a kind of insulation drainpipe, especially a kind of heat insulation drainpipe of air-conditioner that is used for.
Background technology
The heat insulation drainpipe of existing air-conditioner is the secondary operations moulding, generally all uses the wrapping of individual layer PBC film and individual layer sponge together, and hot briquetting can not be formed one, and long-time use fractures easily, wears out, leaks.Be that the heat-insulation layer individual layer separates, heat insulation effect is undesirable.
Summary of the invention
The purpose of this utility model provides a kind of sound construction, weak point not easy to break, the heat insulation drainpipe of good effect of heat insulation, and it has overcome the shortcoming that above-mentioned prior art exists.
The purpose of this utility model is achieved in that and includes external protection, heat-insulation layer and inner tube; the described heat-insulation layer outside is provided with external protection, is provided with interlayer between the heat-insulation layer, and the heat-insulation layer in the interlayer is with inner tube; described inner tube is provided with containing cavity, is provided with reinforcement in it.
Described heat-insulation layer is a high-density sponge.
Described containing cavity is a spirality.
Described reinforcement is made by spirality polypropylene material, and it is sleeved in the spirality containing cavity of inner tube.
Because the utility model has adopted said structure, compared with prior art have the following advantages: good heat-insulation effect, heat-insulation layer are double-decker, and be two-layer for absolute construction is independent of each other, and both increased heat insulation effect, again sound construction, not easy fracture; Install whole spirality reinforcement on the drainpipe inner tube additional, make drainpipe more firm.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an inner tube structural representation of the present utility model;
Fig. 3 is a sectional side view of the present utility model.
Among the figure: 1. external protection; 2. heat-insulation layer; 3. interlayer; 4. reinforcement; 5. inner tube.
The specific embodiment
Drainpipe is by being made up of external protection 1, heat-insulation layer 2 and inner tube 5, and wherein the outermost at drainpipe is an external protection 1, and it can select for use anti-aging PBC material to make.The inboard of external protection 1D is two-layer heat-insulation layer 2, also is provided with interlayer 3 between two-layer heat-insulation layer 2, and making between the two-layer heat-insulation layer 2 like this is absolute construction; both increased heat insulation intensity; drainpipe about layer when folding is not influenced, increase drainpipe intensity, interlayer 3 can be made with common PBC material.On inner tube 5 outer walls of drainpipe, be integrally formed with spiral containing cavity, be set with the reinforcement of making by spirality polypropylene (PP) material 4 in the containing cavity, it makes in the containing cavity that is directly injection-moulded on inner tube 5 outer walls in manufacturing inner tube 5, inner tube 5 can be selected high temperature resistant PBC material for use, and reinforcement 4 is drawn materials according to the length of drainpipe.Heat-insulation layer 2 can be high-density sponge or other cellular insulants.Owing to be provided with reinforcement 4 in the drainpipe, and reinforcement 4 is overall structures during use, thus strengthened the intensity and the toughness of drainpipe, because of heat-insulation layer 2 is two-layer absolute construction,, durable in use again so the drain structure of present technique is firm.General manufacturing process is as follows:
3. heat-insulation layer unit: charging → foamable → stock mould → traction is combined on the inner tube
4. interlayer unit: charging → heating plasticizing → stock mould → be combined in inner tube hard-pressed bale thermal insulation layer
5. external protection: a whole set of tube surface of charging → heating plasticizing → stock mould → be combined in
So heat insulation drainpipe manufacturing success novel, that high strength anti is aging.
The concrete size of heat insulation drainpipe can be made as required.
