Description

Technical Field

[0001] The utility model relates to the technical field of building drainage pipe construction, in particular to a fixing bracket for building drainage pipes. Background Art

[0002] Drainage pipes refer to the system composed of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater. Including main pipes, branch pipes and pipes leading to treatment plants. No matter whether they are built on the street or anywhere else, as long as they are used for drainage, they should be counted as drainage pipes. Drainage pipe engineering is also called "sewer pipe engineering". It is divided into two types: outdoor pipe engineering and indoor pipe engineering. Outdoor pipe engineering refers to the installation of outdoor drainage (sewer) pipes from the drainage inspection well outside the building to the drainage main pipe inspection well. The pipelines outside the main pipe inspection well are under the responsibility of the municipal engineering department. Indoor pipe engineering refers to the installation of drainage pipes and sanitary equipment within the building. The function of drainage pipes is to discharge the dirt and sewage of sanitary equipment outside the building. When the drainage pipe passes through the floor, it needs to pass through the reserved holes. The position of the reserved holes on each floor will deviate during construction, and the distance from the wall is different. In addition, a pipe fixing bracket can only fix a pipe of one diameter. The pipe clamp of each fixing bracket must be replaced according to the pipe diameter, and the versatility is poor. Therefore, designers are required to design a fixing bracket that can adjust the length and adapt to different pipe sizes. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] like Figure 1As shown, the first embodiment of the fixed bracket includes an upper locking ring 1, a lower locking ring 2, a stopper 3, a lifting rod 4, and a fixing seat 6. The upper locking ring 1 and the lower locking ring 2 are connected together by bolts, and the drainage pipe passes through the circular through hole formed by the upper locking ring 1 and the lower locking ring 2. The stopper 3 is welded and connected to the outer bottom surface of the lower locking ring 2. A circular hole is provided at the bottom of the stopper 3, and the axis of the circular hole is vertically downward and perpendicular to the pipe. The top of the lifting rod 4 extends into the circular hole. A plurality of spherical grooves are provided along the circumference on the cylindrical surface of the lifting rod 4, and at least one threaded hole is provided on the stopper 3. The set screw 7 is screwed into the threaded hole and pressed into the spherical groove to prevent the lifting rod 4 from rotating or falling off from the stopper 3.

[0018] The lower part of the fixing seat 6 is fixedly connected to the wall by bolts. The upper part of the fixing seat 6 is a sleeve structure, and the lifting rod 4 extends into the sleeve. The lifting rod 4 is a section of round tube, and a plurality of through holes are provided along the length direction. The pin 5 passes through the lifting rod 4 and the fixing seat 6 to connect the fixing seat 6 with the lifting rod 4. The pin 5 can be a smooth shaft with a hole on the top, and a split pin is provided in the hole. The pin 5 can also be threaded on the top, and a nut is connected after passing through the fixing seat 6 and the lifting rod 4. The pin 5 passes through the round holes of different heights on the lifting rod 4 to change the height of the bracket, thereby adjusting the distance between the pipeline and the wall. When replacing the locking ring, just loosen the set screw 7, and the lifting rod 4 is disengaged from the locking ring for replacement.
