[0017] The following description is only the preferred embodiment of the utility model, and does not limit the protection scope of the utility model.

[0018] A kind of building drain pipe protective sleeve pipe, as shown in Figs. 1-3 The utility model discloses a positioning piece is driven in the sliding slot by pulling the pull rope, and the positioning piece gradually closes inwards and is in close contact with the outer wall of the drain pipe, and then the drain pipe is fixed, thereby adapting the installation demand of different pipe diameter drain pipes, improving the adaptability of the protective sleeve pipe, multiple positioning pieces cooperate with each other, avoiding local stress concentration, thereby ensuring the uniformity of clamping, and the fastening screw is pressed to the pull rope through the thread pressure, forming mechanical self -lock, which can effectively prevent the positioning piece from retracting due to pipeline vibration or water flow impact, and improve the stability of clamping force.

[0019] It should be noted that the building drainage pipeline is an important part of the building internal system, responsible for effectively discharging domestic sewage, rainwater and the like from the building interior, preventing water accumulation and potential health risks, for protecting the drainage pipeline from external factors, a protective sleeve is usually installed outside the drainage pipe, in the initial state, the positioning piece 6 is located inside the adjacent chute 4, reserving enough fixing space for the drainage pipe, first, the protective sleeve 1 is sleeved outside the drainage pipe, the reinforcing ring 2 can improve the overall compression resistance of the protective sleeve 1, then the operator pulls the pull rope 7 outward, the spherical structure on the pull rope 7 provides a force application fulcrum, drives the positioning piece 6 to slide outward along the adjacent chute 4, the inclined surface structure outside the chute 4 makes the positioning piece 6 gradually close inward during sliding, the sliding ring 5 can drive the adjacent positioning piece 6 to slide outward at the same time, thereby realizing the synchronism of sliding, until the positioning piece 6 contacts and fixes the drainage pipe, thereby adapting to drainage pipes of different diameters, when the positioning piece 6 moves to the target position, the fastening screw 8 is rotated, so that the pull rope 7 is in close contact with the adjacent fastening screw 8, the pull rope 7 is compressed by the thread pressure, preventing the positioning piece 6 from retracting, thereby realizing mechanical locking, for isolating external corrosive media from eroding the fastening screw 8, the hidden frame 9 can be rotated to cover the fastening screw 8, which is conducive to prolonging the service life of the fastening screw 8, thereby ensuring the stability of the positioning piece 6 in fixing the drainage pipe.
