[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides a technical solution, which is... Figures 1-4 As shown, a convenient installation and connection structure for a municipal drainage pipe includes: an annular rotating shell 1, with fastening threads of opposite directions on both sides of its inner wall; two symmetrically arranged connecting sleeves 2, located in the central area inside the annular rotating shell 1 and slidably connected to the annular rotating shell 1, with sliding sealing rings 3 provided at their sliding contact positions; an annular inner baffle 4 installed on the inner side of the connecting sleeve 2, with elastic sealing rings 5 ​​provided on the side of the annular inner baffle 4; a sealing gasket 6 provided on the inner wall of the connecting sleeve 2; an external threaded baffle 9 provided at one end of the outer side of the connecting sleeve 2, the external threaded baffle 9 being located inside the annular rotating shell 1 and connected with the fastening threads; and a sealing gasket 10 provided between the external threaded baffle 9 and the annular rotating shell 1.

[0035] In this embodiment of the invention, by fully retracting the connecting sleeve 2 inside the annular rotating shell 1, the device can be easily and quickly installed at the junction of two drain pipes, making the installation more convenient and faster. By extending the connecting sleeve 2 outside the annular rotating shell 1, it can be fitted onto the drain pipe, thereby completing the connection of the two drain pipes. The installation process is simpler and faster, effectively reducing the installation time and saving labor costs.

[0036] In this embodiment of the invention, the sliding sealing ring 3 can seal the gap between the annular rotating shell 1 and the connecting sleeve 2 to prevent external impurities from entering the annular rotating shell 1; the sealing gasket 6 can seal the gap after the connecting sleeve 2 is fitted onto the drain pipe; the elastic sealing ring 5 ensures that when the connecting sleeve 2 drives the annular inner baffle 4 to press against the drain pipe port, the elastic sealing ring 5 can be pressed to maintain a sealed connection between the connecting sleeve 2 and the drain pipe; at the same time, the external threaded baffle 9 presses the sealing gasket 10 against the inner wall of the annular rotating shell 1 to seal the external threaded baffle with the annular rotating shell 1. The multiple sealing features ensure the airtightness of the connection structure and prevent water leakage.

[0037] Multiple transverse positioning rods 7 are evenly arranged inside the annular rotating shell 1. The two ends of the transverse positioning rods 7 are located inside the annular inner baffle 4 and slide in contact with it. A fixed short rod 8 is provided at the center of the transverse positioning rods 7, and the fixed short rod 8 is fixedly connected to the inner wall of the annular rotating shell 1.

[0038] In this embodiment of the utility model, the horizontal positioning rod 7 is used to position the annular inner baffle 4 by sliding support of the rod, thereby improving the stability of the device and preventing the connecting sleeve from shifting or loosening during installation and use.

[0039] One end of the connecting sleeve 2 has multiple evenly distributed fastening grooves 11, and a positioning stud 12 is provided in the fastening groove 11. The positioning stud 12 is welded to the outside of the drain pipe. A wing nut 13 is installed on the positioning stud 12 and is located in the fastening groove 11.

[0040] In this embodiment of the utility model, the positioning stud 12 is welded to the drain pipe and fastened with the wing nut 13, so that sufficient friction is generated between the connecting sleeve 2 and the drain pipe, thereby ensuring the firmness of the connection between the connecting sleeve 2 and the drain pipe and avoiding water leakage caused by the drain pipe loosening due to external vibration and other factors.

[0041] In this invention, the length of the connecting sleeve 2 is less than half the width of the annular rotating shell 1; this allows the connecting sleeve 2 to be completely retracted into the annular rotating shell 1, thereby facilitating the installation and disassembly of this connection structure.

[0042] In this invention, the inner diameter of the connecting sleeve 2 is the same as the outer diameter of the municipal drainage pipe, and the inner diameter of the annular inner baffle 4 is smaller than the inner diameter of the municipal drainage pipe; thus ensuring the airtightness of the connection between the connecting sleeve 2 and the municipal drainage pipe.

[0043] In this invention, the width of the annular rotating shell 1 is the same as the distance between the ports of the municipal drainage pipe; after the connecting sleeve 2 is fully extended, it can compress the municipal drainage pipe to ensure the airtightness of the connection.

[0044] In this utility model, rotating seats 14 are evenly provided on the outer side of the annular rotating shell 1, and rotating handles 15 are installed on the internal threads of the rotating seats 14; the installation of rotating handles 15 can facilitate the operator to rotate the annular rotating shell 1.

[0045] In this invention, the surface of the transverse positioning rod 7 is coated with a wear-resistant coating to extend its service life and prevent the transverse positioning rod 7 from being corroded, which would affect the positioning accuracy of the annular inner baffle 4.

[0046] In this invention, the end of the connecting sleeve 2 is provided with a guide bevel; this facilitates the insertion of the municipal drainage pipe.

[0047] When using this utility model, the staff adjusts the distance between the ports of the two municipal drainage pipes to the same distance as the width of the annular rotating shell 1. Then, the entire connecting mechanism is placed between the two municipal drainage pipes, and by moving laterally, the port of one of the drainage pipes is inserted into the corresponding connecting sleeve 2. At this time, a certain gap is generated between the entire connecting mechanism and the other drainage pipe.

[0048] At this time, the staff installs the rotating handle 15 into the rotating seat 14, and then pushes the rotating handle 15. Since the device is mounted on one of the municipal drainage pipes, the friction generated by the sealing gasket 6 between the connecting sleeve 2 and the municipal drainage pipe causes the annular rotating shell 1 to rotate. At the same time, the staff manually holds the annular inner baffle 4 inside the other connecting sleeve 2 to keep it stationary. Then, the staff can push the rotating handle 15 to make the annular rotating shell 1 start to rotate.

[0049] As the annular rotating shell 1 rotates, the two connecting sleeves 2 remain stationary, allowing the connecting sleeves 2 to gradually extend out of the annular rotating shell 1 via the threaded connection between the external threaded baffle and the annular rotating shell 1.

[0050] After the connecting sleeve extends, the worker keeps the connecting sleeve 2 fixed so that it does not rotate, and then uses the rotating handle 15 to drive the annular rotating shell 1 to continue rotating, so that the connecting sleeve 2 continues to extend and the annular rotating shell 1 moves to another municipal drainage pipe and is fitted onto the other municipal drainage pipe.

[0051] As the two connecting sleeves 2 gradually extend, the annular inner baffle 4 gradually contacts the end face of the municipal drainage pipe. When the annular rotating shell 1 generates greater resistance when rotating, the device is installed between the two municipal drainage pipes. At this time, the annular inner baffle 4 gradually seals with the municipal drainage pipe by squeezing the elastic sealing ring 5, and seals with the outer wall of the municipal drainage pipe by squeezing the sealing gasket 6. At the same time, the external threaded baffle squeezes the sealing gasket 10, so that the external threaded baffle 9 seals with the inner walls of both sides of the annular rotating shell 1, thereby ensuring the airtightness of this connection mechanism.

[0052] Finally, the staff inserted the positioning stud into the fastening groove according to the corresponding position of the fastening groove 11, and welded it to the municipal drainage pipe using a welding tool. Then, the wing nut 13 was installed, so that the wing nut 13 was installed on the positioning stud 12 and fastened to the outer wall of the connecting sleeve 2.

[0053] In the specific implementation of this utility model, in order to avoid the problem of inconvenience in welding the positioning stud 12 after the connection mechanism is installed, the workers can mark the corresponding position on one of the municipal drainage pipes according to the position of the fastening groove 11 on the connecting sleeve 2, and then weld the positioning stud 12 to this municipal drainage pipe first. Then, use a tool to measure the position of the positioning stud 12 on the other municipal drainage pipe, and then weld the positioning stud 12 to the other municipal drainage pipe. Then, the installation can be carried out in the above manner.
