A kind of window insulating interlayer film
Technical field
The utility model relates to a kind of window insulating interlayer film, belongs to technical field of living goods.
Background technology
At present, the window of most of building adopts single layer designs more, but the individual layer window, especially the seal of individual layer steel casement door window is relatively poor, and heat insulation effect is not good.Though can use some insulation measures, as fan, heating installation, air-conditioning etc., because the conduction of heat of individual layer window is fast, sealing is poor, must cause energy waste, and expenditure increases.In long-term use, the steel casement of some outdated buildings also gets rusty easily, and part-structure easily comes off, and becomes potential safety hazard, influences quality of life.In order to increase the heat-insulating property of window, people select for use double window to replace single window usually, to reach the purpose of heat preservation and soundproof, but install, change the step trouble of double window, expense is higher, because the open degree of this window is little, caused indoor air flow property relatively poor, though played the airtight effect that is incubated when closing,, made that indoor ventilation effect is relatively poor because the open degree of push-and-pull window is little.
The utility model content
The purpose of this utility model is at the problems referred to above, proposes a kind of window insulating interlayer film, avoids the defective of individual layer window insulation obturation effect difference and double window cost height, ventilation effect difference.
In order to reach above purpose, to solve above technical problem, window of the present utility model insulating interlayer film comprises plastic film, and the area of described plastic film is identical with corresponding sash housing, and its four limit is shaped on turnover edge inwardly.During use, the turnover edge is buckled on the outer facade of corresponding sash, can between plastic film and window light, forms air blanketing, thereby produce heat insulation effect.
Tightr for plastic film and sash are fitted, it is that the middle part of described plastic film is fixed and the identical liner cuboid of corresponding sash inside casing (being window-glass) that the utility model further improves.In order to save material, this liner cuboid also can be replaced by liner rectangle frame.
The utility model ingenious conception, simple in structure, easy installation and removal can be tailor-made by the size of different sash.In use neither influence the folding of sash, can play the effect of long-term insulating interlayer again, also protected window frame simultaneously.Can be modified plastic film, can also be played effect attractive in appearance.Long service life of the present utility model and safety, cost economy.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the structural representation of the utility model embodiment two.

The specific embodiment
Embodiment one
Structural representation of the present utility model as shown in Figure 1, the area of plastic film 1 coincide with corresponding sash housing size, during use, inwardly turnover edge 2 around the plastic film 1 is buckled on the window frame, itself and the outer facade of sash are fastened, can between plastic film and window light, form air blanketing, thereby produce heat insulation effect.
Embodiment two
As shown in Figure 2, middle part at plastic film 1 is fixed and the identical liner cuboid 3 of corresponding sash inside casing (being window-glass), using method is identical with embodiment one, and it is tightr that this embodiment fits whole plastic film and sash, plays the effect of interlayer heat-insulating.
Embodiment three
As shown in Figure 3, the fixing and identical liner rectangle frame 4 of corresponding sash inside casing (being window-glass) at the middle part of plastic film 1 also can be fitted in rectangle frame 4 on glassly, makes its sealing.Using method is identical with embodiment one, and this embodiment can save material.
In addition to the implementation, the utility model can also have other embodiments, as directly getting the plastic film that coincide with corresponding sash housing, directly is bonded in sticker on the outer facade of sash; Liner cuboid and liner rectangle frame are made hollow or solid etc.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
