The inflatable enclosure comprises a frame 1 arranged around an object, feet 2 supporting the frame 1, a covering 3 covering the object and a retractor 4 rolling the covering 3. The extension member 4 is swingably provided on the frame 1. The supporting feet 2 are connected with the corner positions of the frame 1.

Police officers need to keep off and shield dead remains when handling personal events or case-mucking events, and protect sites. Preferably, the article is a remains.

The frame 1 is arranged horizontally. Preferably, the feet 2 are in four groups. The supporting feet 2 are arranged in the up-down direction. The upper ends of the supporting feet 2 are connected with the corner positions of the frame 1. When a remains is found, the inflatable fence is moved to the remains, the remains are covered by unfolding the shielding member 3, the shielding member 3 is prevented from touching the remains, and the site protection is completed.

The main channel 31 of the support frame 1 and the branch channel 32 of the support shield 3 are formed in the shield 3. The main channel 31 opens on both sides in the direction of the frame 1 in the screening member 3. The branch passages 32 are communicated in parallel between the adjacent main passages 31.

Preferably, the shutter 3 is an airbag. The number of main channels 31 in the shutter 3 is two, and the number of sub-channels 32 in the shutter 3 is several. A main passage 31 is formed in the shutter 3 in the left-right direction. Both ends of the branch passage 32 are respectively communicated with the main passage 31. The shutter 3 is provided with a one-way valve and a relief valve. The check valve communicates with the main passage 31. The relief valve communicates with the main passage 31.

After the shielding member 3 is unfolded, the one-way valve is communicated with a gas source, the gas enters the shielding member 3, the main channel 31 and the branch channel 32 are filled with the gas, and the main channel 31 and the branch channel 32 support the inflatable fence. When the shielding piece 3 needs to be wound, the decompression valve is opened to exhaust, and the shielding piece 3 is wound after the exhaust is completed.

After the main channel 31 is filled with gas, the frame 1 is supported, and the branch channel 32 is filled with gas to support the shielding member 3, so that the inflatable enclosure structure is firm.

Preferably, the gas is air. Sometimes, in order to ensure rapid unfolding of the shielding member 3, when the shielding member 3 is in the rolled state, the air source is communicated through the one-way valve, and air can rapidly enter the shielding member 3 through the one-way valve, the main channel 31 and the branch channel 32 are rapidly filled with air, and the main channel 31 and the branch channel 32 are in an expanded state. Rapid deployment of the shield 3 is accomplished by rapid expansion of the main channel 31 and the branch channel 32.

After the main channel 31 is filled with gas, the main channel 31 in an expanded state plays a role in supporting the frame 1 and plays a role in structurally reinforcing the telescopic structure of the frame 1.

The main channels 31 in the shutter 3 are distributed in the front-rear direction. The branch passages 32 are distributed in the shade 3 in the left-right direction.

The front ends of the branch passages 32 communicate with the main passage 31 located on the front side. The rear end of the branch passage 32 communicates with the main passage 31 located on the rear side. The gas first enters the main channel 31, the gas flows along the main channel 31, the gas in the main channel 31 enters the branch channel 32, and the gas flows along the branch channel 32.

By the gas flowing into the branch passage 32, the inside of the branch passage 32 is inflated, so that the shielding member 3 is unfolded into a plane, so that the shielding member 3 can shield the article.

At the same time, the shielding member 3 is not influenced by the environment, and the shielding member 3 can also shield objects if no air is introduced after the shielding member 3 is unfolded. However, when the screen 3 is blown by wind, the screen 3 swings. However, when the main passage 31 and the sub-passages 32 are filled with air, the shutter 3 does not swing when the shutter 3 is blown by wind.

When the gas is filled into the shielding member 3, the check valve ensures that the gas does not flow back when entering the shielding member 3, and the gas in the shielding member 3 cannot leak after the shielding member 3 is filled with the gas.

The leakage of gas after filling of the gas in the shutter 3 is likewise avoided by the pressure relief valve. When the shielding member 3 needs to be wound, a pressure relief valve is opened, and the pressure relief valve discharges the gas in the shielding member 3. By winding up the shutter 3, the gas in the shutter 3 is discharged through the relief valve.

The one-way valve communicates with the rear side of the left end of the shutter 3. The relief valve communicates with the front side of the left end of the shutter 3.
