When the supporting device 200 is retracted, the first supporting mechanism 220, the second supporting mechanism 230, the third supporting mechanism 240 and the fourth supporting mechanism 250 can surround to form an accommodating space 290, and the tarpaulin structure 100 can be accommodated in the accommodating space 290 after being retracted and the cross beam 280 is folded, so that the portability of the isolation system 10 during retraction is improved.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention, and it is therefore to be understood that the invention is not limited by the scope of the appended claims.

Claims

1. An obturator, comprising:

2. The closing device as claimed in claim 1, wherein the tarpaulin structure further comprises a tarpaulin body, the opening and closing mechanism comprises two opening and closing parts, and a magnetic member is disposed between the two opening and closing parts and between the opening and closing parts and the tarpaulin body.

3. The sealing device as claimed in claim 2, wherein the opening/closing portion has a first side, a second side, a third side and a fourth side arranged along a circumferential direction of the opening/closing portion, the first sides are arranged oppositely, the second side is arranged away from the first sides and is integrated with the tarpaulin body, and the third side and the fourth side are sealed with the tarpaulin body through the magnetic attraction member.

4. The closing device according to claim 2, further comprising a driving mechanism for driving the opening and closing mechanism to move.

5. The closing device according to claim 4, wherein the opening and closing part is a flexible structure, and the driving mechanism can drive the two opening and closing parts to be folded away, so that the opening and closing mechanism opens the sealed cavity.

6. The closure of claim 5, further comprising a sliding mechanism, wherein the sliding mechanism comprises a sliding frame and a pulley, wherein the sliding frame is connected to the frame structure, and the pulley is connected to the opening and closing portion and slidably disposed on the sliding frame.

7. The closing device as claimed in claim 2, wherein the tarpaulin body is provided with a transparent part and a shielding part, and the shielding part can shield or open the transparent part.

8. The enclosure of claim 1, wherein the tarpaulin structure is provided with a wire passing structure, the wire passing structure being capable of passing a wire therethrough and being further capable of being closed to isolate the sealed cavity from the external space.

9. The closing device as claimed in claim 1, wherein said tarpaulin body is provided with a folding part, said folding part is laid on the working surface and is arranged opposite to said opening and closing mechanism.

10. An isolation system, comprising:

a closure as claimed in any one of claims 1 to 9; and
