Embodiment Construction
[0012] refer to Figure 1~3 , an article buffer protection device capable of automatically adjusting pressure, comprising an air bag and an air pressure controller for controlling the air pressure in the air bag, the air pressure controller includes a casing 2, an overflow valve 3, a gas cylinder 5, and a pressure reducing valve 8. The air bag, relief valve 3 and pressure reducing valve 8 can be connected through a three-way pipe 1, the first end of the three-way pipe 1 is connected to the air bag, the second end is connected to the pressure reducing valve 8, and the third end is connected to the relief valve 3.
[0013] The gas cylinder 5, the pressure reducing valve 8, and the air bag are connected in sequence to form an air path. The gas in the gas cylinder 5 can be carbon dioxide, and when the air pressure in the air bag is too low, the gas in the gas cylinder 5 enters in the air bag through the pressure reducing valve 8 to ensure that the gas in the air bag is sufficient ...

The invention provides an object buffering protection device capable of automatically adjusting the pressure. The object buffering protection device comprises a gasbag and a gas pressure controller for controlling the gas pressure in the gasbag; the gas pressure controller comprises a shell, an overflow valve, a gas bottle and a reducing valve; the gas bottle, the reducing valve and the gasbag aresequentially connected to form a gas channel; an inlet of the overflow valve is connected with the gas channel, and an outlet of the overflow valve is connected with a damping hole in the shell; anda first adjusting rotary knob for controlling the pressure of gas output into the gasbag by the reducing valve is arranged on the reducing valve, and a second adjusting rotary knob for adjusting the threshold gas pressure of the released gas is arranged on the overflow valve. When the gas pressure in the gasbag is lower than a set value, the gas in the gas bottle automatically flows into the gasbag through the reducing valve to ensure the safety of goods; and when the gas pressure in the gasbag exceeds the threshold gas pressure of the overflow valve due to a collision and other reasons, the overflow valve is opened, and the excess gas is released through the damping hole till the gas pressure in the gasbag reaches the set value.
Description
technical field [0001] The invention relates to an article buffer protection device capable of automatically adjusting pressure, especially as a buffer protection device during the transportation of precious and vulnerable items such as precision electronic instruments and handicrafts. Background technique [0002] Airbags made of polyethylene, nylon and other materials are mainly used for cushioning packaging during cargo transportation, but most of the cushioning airbags are disposable and discarded after use, wasting resources and polluting the environment. This kind of disposable airbag cannot adapt to changes in external pressure. If a collision occurs during transportation, the air pressure of the airbag will suddenly increase, and the pressure will directly act on the cargo. In severe cases, the airbag and the cargo will be damaged. Contents of the invention [0003] The invention provides an article buffer protection device capable of automatically adjusting pressu...
