Description

Technical Field

[0001] The utility model relates to the technical field of wall-penetrating pipes, in particular to a waterproof and airtight structure of a wall-penetrating pipe. Background Art

[0002] Wall pipe is a type of piping material, typically made of plastic materials such as PVC, HDPE, and ABS, with a metal expansion joint. It can be used to connect pipes through buildings, obstacles, and other places. Because of its strength and toughness, it is not easily broken when passing through building walls and other structural materials such as reinforced concrete. Wall pipe, also known as wall sleeve or waterproof sleeve, is mainly divided into two types: rigid waterproof sleeve and flexible waterproof sleeve.

[0003] Based on the above, the inventors have discovered the following problems: During the installation process of existing wall-penetrating pipes, the pipe body cannot perfectly fit into the reserved hole in the wall, and there may be gaps. Currently, sealants are mostly used to fill the gaps to achieve a sealing effect. However, the curing time of the sealant will be affected by the ambient humidity and temperature. Especially in dry or cold environments, the curing speed is slow, which may affect the construction progress.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a waterproof and airtight structure of a wall-penetrating pipe is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0035] Specifically, the working principle of the waterproof and airtight structure of the wall-penetrating pipe is as follows: when in use, a center hole 1001 is opened on the wall 100 to facilitate the insertion of the wall-penetrating pipe body 2001. At this time, the air bag 2002 outside the wall-penetrating pipe body 2001 is in a deflated state. The user unscrews the blocking block 2004 and introduces air into the air bag 2002 through the air inlet pipe 2003. The air enters the air bag 2002 through the silicone one-way valve, causing the air bag 2002 to expand, so that the outer wall of the air bag 2002 is pressed against the inner wall of the center hole 1001, thereby achieving The through-wall pipe body 2001 is waterproof and gas-proof. A silicone one-way valve is provided to allow air to circulate in only one direction to prevent backflow or reflux. After the subsequent air injection is completed, the user can re-tighten the blocking block 2004. By opening the mounting hole 1002, it is convenient to install the first connecting seat 1003. By opening a circular hole 600 at the center of the sealing seat 1004 and the sealing cover 400, it is convenient to align the circular hole 600 at the center of the sealing seat 1004 or the sealing cover 400 with the through-wall pipe body 2001, and then seal it. The seat 1004 or the sealing cover 400 is sleeved on the outside of one end of the wall-penetrating tube 2001. By embedding magnet blocks on the opposite sides of the first connecting seat 1003 and the second connecting seat 1005, when the opposite pair of magnet blocks attract each other, the two sealing seats 1004 are fixed to the front and back sides of the wall 100 respectively. Then, by setting a ring 1015, it is convenient for the user to hook the ring 1015 with his fingers and then pull the ring 1015 toward the outside of the mounting seat 1010 to realize the movement of the connecting rod 1013. When the connecting rod 1013 moves toward the outside of the mounting seat 1010, This makes it easy to pull the block 1012 so that it squeezes the spring 1014 and continuously shrinks into the mounting seat 1010. After the sealing cover 400 is inserted into the sealing seat 1004, the hanging ring 1015 is loosened, so that the block 1012 is inserted into the first square groove 1008, the second square groove 500 and the third groove 1009 under the elastic force of the spring 1014, thereby realizing the connection between the sealing cover 400 and the sealing seat 1004. The end of the sealing cover 400 located inside the sealing seat 1004 is against the sealing ring 1007, thereby further improving the sealing performance.
