A rubber plate (2) is fitted on the through pipe (1) to seal holes of different diameters in cooperation with the fixed plate (3). The diameter of the rubber plate (2) is not less than that of the fixed plate (3).

2. The waterproofing device for a post-punched wall according to claim 1, characterized in that: The fixed plate (3) has a through hole (20) that communicates with the through tube (1). On the upper and lower sides of the through hole (20), the fixed plate (3) has an L-shaped limiting groove (15) opposite to it. The L-shaped limiting groove (15) has a baffle (14) that blocks the through hole (20).

3. The waterproofing device for a post-punched wall according to claim 2, characterized in that: A limiting plate (16) for limiting the baffle (14) is provided on either side of the two L-shaped limiting grooves (15).

4. The waterproofing device for a post-punched wall according to claim 2 or 3, characterized in that: The top of the fixed plate (3) is provided with a rubber rain shield (4) to waterproof the through hole (20).

5. A waterproofing device for post-opening walls according to any one of claims 1-3, characterized in that: A through hole is provided on the through tube (1); The fixing component (19) includes two first brackets (13) arranged parallel to the through tube (1), two second brackets (12) perpendicularly connected to the two first brackets (13), a moving cavity (21) is formed between the two second brackets (12), and a limiting hole (22) corresponding to the through hole is provided on the second bracket (12). An elastic reset member (23) fixed on the hole is provided on the limiting hole (22) and the through hole.

6. The waterproofing device for a post-punched wall according to claim 5, characterized in that: The elastic reset component (23) includes a movable rod (8) that slides through the limiting hole (22) and the through hole. The movable rod (8) located on one side of the moving cavity (21) is provided with a handle (10) for operation on the side of the through hole (20). A positioning plate (7) is provided on the movable rod (8) between the through tube (1) and the second bracket (12). A reset spring (9) sleeved on the movable rod (8) is provided on the positioning plate (7) and the second bracket (12).

7. The waterproofing device for a post-punched wall according to claim 6, characterized in that: The second bracket (12) is also provided with a movable hole (5), and the positioning plate (7) is provided with a limiting rod (11) that slides with the movable hole (5).

8. A waterproofing device for a wall with a post-opening structure according to claim 6, characterized in that: A rubber block (6) is provided on the movable rod (8) on the opposite side of the handle (10).

9. The waterproofing device for a post-punched wall according to claim 1, characterized in that: The diameter of the rubber disc (2) is larger than the diameter of the fixed disc (3).

10. The waterproofing device for a post-punched wall according to claim 1, characterized in that: The rubber disc (2) is either attached to or separated from the fixed disc (3).
