Technical Field
[0001] This utility model relates to the field of waterproof sleeve technology, and in particular to a waterproof sleeve for preventing wall leakage. Background Technology
[0002] Currently, the filling material for walls is mostly concrete bricks. These new materials have a large drying shrinkage deformation, and the water absorption rate of the masonry is relatively high. Therefore, in order to install pipes that penetrate the wall, waterproof sleeves are generally pre-installed inside the wall to prevent water inside the wall from entering the room or the pipes through the pipes.
[0003] During use, the waterproof ring may be damaged or reach the end of its lifespan. At this time, because the waterproof ring is stuck in the embedded groove, it is difficult to remove and replace the waterproof ring. The waterproof function of the device will become worse and worse. Therefore, a waterproof sleeve to prevent wall leakage is proposed. Utility Model Content

Each mounting seat includes a placement ring and a fastening ring. The inner wall of the placement ring has a waterproof groove for mounting the waterproof ring. The inner diameter of the placement ring, the inner diameter of the waterproof ring, and the inner diameter of the pipe body are all consistent. The fastening ring has several moving rods on its side near the pipe body. The placement ring has a guide slope for the inner diameter of the fastening ring to abut against and control the placement ring to move towards the central axis of the pipe body. The pipe body has a fixing assembly for fixing the moving rods after they slide into the moving groove.
[0006] As a further embodiment of this utility model, the fixing component includes a guide block located on the moving rod and a fixing screw threaded onto the pipe body. The guide block is provided with a guide surface for the fixing screw to abut against and control the moving rod to move towards the pipe body. By adopting the above technical solution, when the moving rod is inserted into the moving groove, the fixing screw moves towards the guide block. Under the action of the moving surface, the moving rod continues to move towards the bottom of the moving groove. At this time, the placement ring is abutted by the inner diameter of the fastening ring, and the placement ring moves towards the central axis of the pipe body, thus achieving the effect of fastening the placement ring onto the pipe. At the same time, the fixing screw threaded onto the pipe body makes the moving rod stable in the moving groove.
[0007] As a further embodiment of this utility model, the side of the fixing screw closest to the guide surface is rounded, and the side of the fixing screw away from the guide surface is provided with a rotating handle. The rounded head facilitates the control of the guide block's movement by the fixing screw. By adopting the above technical solution, the rotation of the fixing screw can be easily controlled by rotating the handle.

By adopting the above technical solution, the possibility of damage to the inner wall of the fastening ring and the guide slope after they come into contact can be minimized.
[0010] As a further embodiment of this utility model, the tube body is provided with a moving groove for the moving rod to slide along the length of the tube body, and the opening of the moving groove is provided with a chamfer. By adopting the above technical solution, the chamfer facilitates the insertion of the moving rod into the moving groove.
[0011] As a further embodiment of this utility model, the placement ring is provided with a limiting component to restrict the sliding of the placement ring along the length direction of the tube. By adopting the above technical solution, the placement ring is pre-fixed to one side of the tube by the limiting component before the fastening ring moves, which facilitates the subsequent fastening of the fastening ring.
[0012] As a further embodiment of this utility model, the limiting component includes several limiting blocks disposed on the end face of the placement ring near the tube body. The end face of the tube body near the placement ring is provided with a limiting groove for the limiting blocks to be inserted into the limiting groove. The limiting groove allows the limiting blocks to move towards or away from the central axis of the tube body. By adopting the above technical solution, the placement ring moves towards the tube body and inserts the limiting blocks into the limiting groove, thus achieving the pre-fixation effect of the placement ring on the tube body.
[0013] This utility model provides a waterproof sleeve to prevent wall leakage, which has the following beneficial effects:
[0014] This waterproof sleeve for preventing wall leakage involves installing a waterproof ring inside a placement ring, then fixing the placement ring to the pipe body using a snap-fit block. A moving rod is inserted into a moving groove to align the fastening ring with the pipe body. Once the pipe is inserted into the pipe body, the moving rod is controlled to move towards the bottom of the moving groove. Under the action of the inner diameter of the fastening ring and the guide bevel, the placement ring pulls the waterproof ring against the pipe. Finally, the fastening ring is fixed to the pipe body using a fixing component. Because the placement ring and the fastening ring are detachably connected to the pipe body, it facilitates the replacement of the waterproof ring. Attached Figure Description
