Description

Technical Field

[0001] The utility model relates to the technical field of buffer inflatable bags, in particular to a device for precisely controlling the air pressure inside a buffer inflatable bag. Background Art

[0002] An air column bag, also known as a buffer air column bag, an inflatable bag, a bubble column bag, or a columnar inflatable bag, provides comprehensive columnar buffer protection and minimizes the product loss rate during transportation. The air packaging bag has anti-stretching and balanced properties, good surface printability, and belongs to a medical-grade substrate. Through continuous pressing, an airtight inflatable column is formed.

[0003] At present, most buffer inflatable bags generally need to be inflated by an inflating device before use. However, when most current inflating devices are in use, they cannot precisely control the air pressure inside the buffer bag. Each time inflation is carried out, only the feeling of the staff can be relied on to control the inflation amount of the buffer bag. If the inflation amount is too large, it is easy to cause the buffer bag to burst. If the inflation amount is too small, the protective strength of the buffer bag is insufficient. Therefore, it is necessary to design an inflating device that can precisely control the air pressure inside the buffer bag to solve the above problems. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a device for precisely controlling the air pressure inside a buffer inflatable bag to solve the problems raised in the above background art.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0023] Please refer to Figures 1-3 , the present utility model includes a pressing chassis 01, a pressing assembly is arranged at the top of the pressing chassis 01, the pressing assembly includes a pressing airbag 011, an exhaust port 012 and an air inlet 013, a connecting assembly is arranged at the exhaust port 012, and the connecting assembly includes a connecting hose 02, a connecting hard pipe 021 and an inflation docking port 022; a pressure component is arranged on the outer surface of the connecting hard pipe 021, and the pressure component includes a one-way valve 03, a micro pressure gauge 031, a valve 032 and a switch 033.

[0024] Please refer to Figure 1 and Figure 2 , in this embodiment, in order to better facilitate the inflation operation of the staff, the pressing airbag 011 is installed at the top of the pressing chassis 01, and both the exhaust port 012 and the air inlet 013 are installed on one side of the pressing chassis 01;

[0025] One-way valves 03 are installed in both the air inlet 013 and the exhaust port 012, and a one-way valve 03 is also installed on the inner wall of the connecting hard pipe 021 near the connecting hose 02.

[0026] When inflation is required, the staff only needs to step on the pressing airbag 011. When stepping on it, the pressing airbag 011 is pressed down to discharge the gas from the exhaust port 012, and the external air enters the inside of the pressing airbag 011 from the air inlet 013, so that the pressing airbag 011 bulges again. By stepping on it repeatedly, the inflation operation can be carried out.

[0027] Please refer to Figure 1 andFigure 3 , it should be noted that in order to more conveniently enable the staff to accurately control the air pressure inside the buffer bag, one end of the connecting hose 02 is docked with the exhaust port 012, and the other end of the connecting hose 02 is connected to one end of the connecting rigid pipe 021;

[0028] One end of the inflation docking port 022 is connected to the other end of the connecting rigid pipe 021. One end of the inflation docking port 022 is a tip, and the diameter of the other end is adapted to the diameter of the connecting rigid pipe 021;

[0029] The micro air pressure gauge 031 is installed at the top of the connecting rigid pipe 021, the air valve 032 is installed at a position near the right side of the micro air pressure gauge 031 at the top of the connecting rigid pipe 021, and the switch 033 is arranged at the top of the air valve 032.

[0030] When it is necessary to inflate the buffer bag, insert the inflation docking port 022 into the inflation port of the buffer bag, and then step on and press the air bag 011 with the foot. The gas is injected into the inside of the buffer bag through the exhaust port 012, the connecting hose 02 and the connecting rigid pipe 021. At this time, the gas inside the buffer bag is communicated with the inside of the inflation docking port 022 and the connecting rigid pipe 021 through the one-way valve 03 inside the connecting rigid pipe 021. At this time, the air pressure after inflation inside the buffer bag can be detected through the micro air pressure gauge 031. Through the pointer data on the micro air pressure gauge 031, the staff can better control the air pressure and inflation volume inside the buffer bag. When the inflation volume is relatively large, the switch 033 can be pressed to discharge a part of the gas inside the buffer bag from the air valve 032, so that the staff can better adjust the inflation volume.

[0031] The above is only the embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
