Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1, the gas column bag of the present embodiment includes: the gas column strip is sealed and filled with protective gas, and a one-way valve is arranged in the gas column strip and divides the internal space of the gas column strip into a plurality of sections. Specifically, the gas column bag comprises a plurality of parallel gas column strips. The air column bag is formed by compression molding of double-layer films, wherein the positions of the air column strips are of non-compression-molded double-layer film structures, and the connecting parts between the adjacent air column strips are of compression-molded single-layer structures. The central line of the connecting part is provided with a splitting line, and the splitting line is provided with a plurality of auxiliary splitting holes, so that the large-area air column bag can be conveniently split.
The gas column strip is divided into a testing section and a protection section by a one-way valve. The test section can be used for testing air pressure, and the protection section mainly plays a role in protection and buffering. The length of the test section is one fourth of the length of the protection section, so that the length of the protection section can be ensured, and the protection effect of the protection section is ensured. The air inlet end of the one-way valve is arranged on one side of the testing section, the air outlet end of the one-way valve is arranged on one side of the protecting section, and the air in the testing section enters the protecting section through the one-way valve. The check valve has an opening air pressure difference threshold, and when the air pressure difference between the test section and the protection section reaches the air pressure difference threshold, the check valve is opened to enable the gas in the test section to enter the protection section.
Designing an air inlet channel in front of the test section, wherein the air inlet channel is communicated with the test section in a one-way mode, and the air flow direction is from the air inlet channel to the test section, so that the integral design of the air column bag is completed; the airflow direction of the whole air column bag is one-way, and the airflow direction is from an air inlet channel to a test section to a protection section; when the air in the protection section leaks, the air pressure in the protection section is reduced, the air in the test section flows into the protection section due to the action of pressure intensity, so that the air pressure in the test section is reduced until the air pressure is consistent with the air pressure in the protection section, and the air pressure value of the whole air column can be obtained by measuring the air pressure in the test section, so that the protection effect of the air column is evaluated; measuring the air pressure value of the air columns of the air column bag one by one, and evaluating the integral protection effect of the air column bag; when the air in the protection section is not leaked and the air in the test section is leaked, the test section is in one-way communication with the protection section, and the air flow direction is from the test section to the protection section, so that the air in the protection section cannot flow to the test section, and the air pressure in the protection section is not influenced; the air pressure values of the air columns of the air column bags are measured one by one, data that the test section is air-leaked and the protection section is not air-leaked are eliminated, and the overall protection effect of the air column bags can be evaluated; when no gas is input manually, the gas pressure in the gas column bag cannot rise; if the air pressure is increased, the air pressure is caused by environmental changes, such as temperature increase, altitude increase and the like; at the moment, the test section and the protection section are both influenced by the environment, the air pressure of the air column is increased, and the air pressure value measured by the test section is consistent with that of the protection section.
Although the present invention has been described in detail by referring to the drawings in connection with the preferred embodiments, the present invention is not limited thereto. Various equivalent modifications or substitutions can be made on the embodiments of the present invention by those skilled in the art without departing from the spirit and scope of the present invention, and these modifications or substitutions are within the scope of the present invention/any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
