Abstract
The utility model belongs to the technical field of the protection film technique and specifically relates to an automatic ventilative protection film. An automatic ventilative protection film, includes the base film, be equipped with the through -hole on the base film, the activity that is equipped with in the through -hole separates shelves, the through -hole top is equipped with the cover membrane, cover membrane one end is passed through the connecting block and is fixed on the base film, the through -hole is issued and is equipped with the deflector, the deflector becomes the loudspeaker form. This kind of automatic ventilative protection film is when using, and the heat messenger air expansion of product production through the effect of inside and outside pressure differential, is that the activity separates shelves and the cover membrane is opened, and then breathes freely that satisfy radiating demand, the result of use is good.
Description
Technical field
This utility model is related to protection of technical field of membrane, especially a kind of air-permeable protective film automatically.
Background technology
Protecting film is bondd by outside air pollution or dust as protection product department; but in some cases, between protecting film and product, there is a space, and product can produce substantial amounts of heat; product can be impacted if heat can not quickly distribute, cause that defect ware occurs.
Utility model content
In order to overcome the deficiency of existing protecting film air permeable effect difference, this utility model provides a kind of air-permeable protective film automatically.
This utility model solves its technical problem and be the technical scheme is that a kind of air-permeable protective film automatically; including basement membrane, described basement membrane is provided with through hole, is provided with movable baffle in described through hole; described through hole is arranged over coverlay, and described coverlay one end is fixed on basement membrane by contiguous block.
According to another embodiment of the present utility model, farther including, described through hole issues and is provided with guide plate, and described guide plate becomes horn-like.
The beneficial effects of the utility model are, when in use, the heat that product produces makes air expansion to this automatic air-permeable protective film; by the effect of external and internal pressure difference, it is movable baffle and coverlay is opened, and then breathe freely; meeting the demand of heat radiation, result of use is good.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model；
In figure 1, basement membrane, 2, guide plate, 3, baffle, 4, through hole, 5, contiguous block, 6, coverlay, 7, holding vessel.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, a kind of air-permeable protective film automatically, including basement membrane 1; described basement membrane 1 is provided with through hole 4; being provided with movable baffle 3 in described through hole 4, described through hole 4 is arranged over coverlay 6, and described coverlay 6 one end is fixed on basement membrane 1 by contiguous block 5.
According to another embodiment of the present utility model, farther including, described through hole 4 issues and is provided with guide plate 2, and described guide plate 2 one-tenth is horn-like.
This automatic air-permeable protective film; when in use; this protecting film is arranged on holding vessel 7; the heat that product in holding vessel 7 produces makes the temperature in holding vessel 7 raise; pressure becomes big; under the impact of holding vessel 7 external and internal pressure difference; hot-air has guide plate 2 guide through hole 4; active clapboard 3 in through hole 4 is strutted, is that coverlay 6 is also raised simultaneously, meet the demand of ventilative heat exchange; when air-locked time; active clapboard 3 and coverlay return simultaneously, it is prevented that dust moisture attacks product, meets user demand.
