Description

Technical Field

[0001] The utility model relates to the technical field of pipeline embedded parts, in particular to an embedded part for water supply and drainage pipes. Background Art

[0002] As we all know, the indoor drainage system collects the water used in daily life and industrial production, and discharges it into the outdoor sewage pipe in time directly or after local treatment. The drainage system is mainly composed of sanitary appliances, drainage pipe system, ventilation pipe system and clearing equipment. The design and installation of water supply and drainage pipes is an indispensable task for modern buildings, especially high-rise buildings.

[0003] Drainage pipe embedded parts are needed in the process of building construction. During the installation of the drainage pipe embedded parts, the drainage pipe embedded parts need to be inserted on one side of the building, and then the staff go to the other side of the building to screw the nuts on the drainage pipe embedded parts to fix the drainage pipe embedded parts on the building, or two staff members cooperate to install them. Therefore, the existing drainage pipe embedded parts are inconvenient to install. Utility Model Content

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an embedded part for water supply and drainage pipes, comprising a wall, a mounting hole is opened on the wall, an embedded pipe fitting is installed inside the mounting hole, the embedded pipe fitting comprises a pipe body, a retaining edge is fixedly provided at one end of the pipe body, a movable sleeve is sleeved on the outside of the pipe body, and a plurality of bendable support frames are provided between the sleeve and the retaining edge.

[0008] The other end of the tube body is connected to a nut through a thread, an outer wall of the tube body is provided with an external thread, and an inner wall of the nut is provided with an internal thread.

[0009] Wherein, a gasket is arranged on one side of the nut close to the sleeve.

[0010] Wherein, anti-slip grooves are arranged on the outer wall of the sleeve.

[0011] Wherein, a rubber ring is arranged on the inner wall of the tube body.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides an embedded part for water supply and drainage pipes, which has the following

[0014] Beneficial effects:

[0015] The embedded part for water supply and drainage pipes is provided with a sleeve and a plurality of bendable support frames. When installing the embedded pipe fittings, the sleeve is first moved away from the retaining edge to straighten the support frame, and then the embedded pipe fittings are installed in the installation hole. After the retaining edge passes through the installation hole, the sleeve is moved close to the retaining edge to make multiple support frames bend at the same time. The bent support frames are supported outside the installation hole, and then nuts are installed on the embedded pipe fittings to complete the installation of the embedded pipe fittings. There is no need for workers to go to the other side of the building for installation, and one person can complete the installation of the embedded pipe fittings, thereby making the installation of the embedded pipe fittings more convenient and improving practicality.
