Description
Technical field
The utility model belongs to a kind of protective articles, and in particular to a kind of portable fit big envelope.
Background technique
In order to protect product, goods and materials, tarpaulin is generallyd use when not in use and is wrapped up, currently, paulin in the market
Although cloth can achieve the purpose that sun-proof dustproof and rainproof, since tarpaulin does not have overall tightness, to the antirust of product, goods and materials
Etc. functions exist it is obvious insufficient.
Summary of the invention
The purpose of the utility model is to provide a kind of portable fit big envelopes, and it is anti-to solve existing product, goods and materials tarpaulin
The problem of protective function deficiency.
The technical solution of the utility model is as follows: a kind of portable fit big envelope, including upper envelope in hollow structure and
Lower big envelope, upper envelope and lower big envelope opening splice the one side of something for having the pressure-sealing zipper that can be kept completely separate respectively, in the side of lower big envelope
Face is equipped with check valve, and check valve connects air exhausting device.
The opening of the upper envelope and lower big envelope is in quadrilateral structure.
The opening of the upper envelope is equipped with shielding plate.
The upper envelope and lower big envelope are using novel high mechanical strength, the composite material of high barrier, the machine of material
Tool intensity is no more than 1.5g/m in 2000N/5cm or more, the water vapour transit dose of material2·24h。
The air exhausting device is aspiration pump.
The utility model has the beneficial effects that: the structure combined using upper and lower big envelope, is attached by pressure-sealing zipper,
It is easy to operate；In lower big envelope side, check valve is set, it is convenient that exhaust is carried out after big envelope is closed completely, make big envelope and product,
Goods and materials are completely fit, avoid the damage because of the product, goods and materials big envelope of the utility model caused by blowing etc., the utility model structure letter
It is single, it is easy to operate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the portable fit big envelope of one kind provided by the utility model.
In figure: 1 upper envelope, 2 lower big envelopes, 3 pressure-sealing zippers, 4 shielding plates, 5 check valves.
Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further detail the utility model.
As shown in Figure 1, a kind of portable fit big envelope includes upper envelope 1 in hollow structure and lower big envelope 2, upper envelope 1
Opening with lower big envelope 2 is in quadrilateral structure, and upper envelope 1 and lower 2 opening of big envelope are spliced respectively the sealing that can be kept completely separate
One side of something of zipper 3, pressure-sealing zipper 3 select metal rice tooth zipper, complete the connection of upper and lower big envelope with can be convenient, formation can be complete
Totally enclosed big envelope is whole；The opening of upper envelope 1 is equipped with shielding plate 4, can cover drawing completely after pressure-sealing zipper 3 closes up
Chain protects zipper not to be damaged；Check valve 5 is housed in the side of lower big envelope 2, check valve 5 can connect air exhausting device and (such as take out
Air pump), the additional air of package interior can be discharged after upper envelope 1 and lower big envelope 2 are closed completely by check valve 5, make to seal
Set is whole fit with product, goods and materials.It can be with making big envelope and product, goods and materials completely fit by way of exhaust.
Using novel high mechanical strength, the composite material of high barrier, the machinery of material is strong for upper envelope 1 and lower big envelope 2
Degree is no more than 1.5g/m in 2000N/5cm or more, the water vapour transit dose of material2For 24 hours, the resistance to ag(e)ing of material can be each
It uses 5 years or more, is able to use under the conditions of various extreme natural environments 5 years or more under kind extreme natural environment.
A kind of portable fit big envelope of the utility model use process is as follows:
When to be protected to product, goods and materials, first lower big envelope 2 is layered on smooth ground, production to be protected will be needed
Product, goods and materials are moved to the centre of lower big envelope 2, are then fully deployed upper envelope 1 from top to bottom and cover on product, goods and materials, and protect
The front and back end position for holding upper envelope 1 is corresponding with lower big envelope 2, and drawing pressure-sealing zipper 3 is closed completely upper envelope 1 and lower big envelope 2
Entirety is formed, the bleeding point of air pump is connected to check valve 5, extracting the additional air in big envelope out pastes big envelope and product, goods and materials
Body.
When product to be used, goods and materials, opening pressure-sealing zipper 3 is kept completely separate upper envelope 1 and lower big envelope 2, by upper envelope 1
It is removed completely from product, goods and materials, product, goods and materials is removed, gathering then is separately folded in upper envelope 1 and lower big envelope 2.
