Abstract
The invention discloses an air-tight door structure. The air-tight door structure is arranged on a gable wall of a tent, and the structure is an L arc shaped double-layer staggering zipper structure; a first layer of zippers is arranged on the front side of a tent body, and a second layer of zippers is arranged on a reverse side of the tent body; the second layer of zippers is sewn on cloth, and the cloth is arranged on the tent body in a heat sealing mode; and the first layer of zippers and the second layer of zippers are arranged in a staggering mode. According to the structure, certain positive and negative pressure values exist inside the tent, and certain pressure differences are formed between the inside of the tent body and the outside of the tent body, so that certain safety guarantees are provided for staffs and goods and materials inside the tent.
Description
Technical field
The present invention relates to a kind of sealed door structure, can satisfy the sealed door structure of internal pressure demand under specifically a kind of situation that has pressure differential at inside and outside environment.
Background technology
At present tent is known by users, is mainly used in field work, tourism, the anti-dangerous disaster relief, military etc.The form of structure of existing tent door mainly contains individual layer zipper, hasp structure, a chain of band structure etc., and these structures all can not satisfy inside and outside situation that has pressure differential of tent at present.If adopt conventional individual layer zipper, need to use special waterproof, air tight slide fastener, have only the slide fastener on the diving dress to satisfy at present, and this slide fastener cost is higher, the customization difficulty, makes difficulty etc.
Summary of the invention
In order to satisfy the specific demand of tent, the purpose of this invention is to provide a kind of sealed door structure, this structure can guarantee that there is certain positive and negative pressure value tent inside, forms certain pressure differential with the outside.Thereby personnel and the goods and materials inner for tent provide certain safety guarantee.
The objective of the invention is to realize through following technical scheme:
A kind of sealed door structure, said sealed door structure is arranged on the gable of tent, it is characterized in that: this sealed door structure is the double-deck dislocation of a L camber zipper; It is positive that the first floor slide fastener is arranged on the paulin body, and second layer slide fastener is arranged on paulin body reverse side; Second layer slide fastener is produced on the cloth, and this cloth is incorporated on the paulin body through elevated temperature heat; First floor slide fastener and second layer slide fastener shift to install.
Among the present invention, said first floor slide fastener and second layer slide fastener are Spiral zipper.The positive and negative structure is directly revealed in order to prevent gas, has considered double-layer structure dislocation making.
The present invention has overcome the defective of material, changes from structure, reaches instructions for use through using conventional material.
Form of structure of the present invention is the double-deck misconstruction of L camber; Be produced on the tent through heat seal process, because the paulin body of tent all adopts heat seal process to handle, so there is not leakage; And the position that can reveal gas has only the zipper teeth position; Through the structure design of bilayer dislocation, make amount of leakage reach minimum, and can satisfy user demand.This structure can guarantee that there is certain positive and negative pressure value tent inside, forms certain pressure differential with the outside.Thereby personnel and the goods and materials inner for tent provide certain safety guarantee.
Compared with prior art, the present invention has novel structure property, function of use particularity, technology making particularity, and can satisfy the special use that will go through the use of conventional material.The present invention's property easy to use, safe is good, durable, have isolation effect.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a cross-sectional view of the present invention.
The specific embodiment
A kind of sealed door structure of the present invention is seen Fig. 1.This structure is the double-deck dislocation of a L camber zipper.It is positive that first floor slide fastener 1 is produced on the paulin body, and second layer slide fastener 2 is produced on paulin body reverse side.Second layer slide fastener 2 structures are incorporated into cloth on the paulin body 4 through elevated temperature heat for being produced on slide fastener on the cloth 3 earlier then.First floor slide fastener 1 is directly revealed in order to prevent gas with second layer slide fastener 2, has considered double-layer structure dislocation making during design.
This structure can guarantee that there is certain positive and negative pressure value tent inside, forms certain pressure differential with the outside.Thereby personnel and the goods and materials inner for tent provide certain safety guarantee.
The present invention's property easy to use, safe is good, durable, have isolation effect.
