[0020] See also Figures 1-4 The utility model provides a technical solution: a municipal drainage pipe sealing rubber ring, including a first connecting pipe 1, a second connecting pipe 2 and a connecting head 3, the connecting head 3 is fixedly connected at one end of the first connecting pipe 1, and the second connecting pipe 2 is located inside the connecting head 3.

[0021] The specific settings and functions of the installation device 4 and the connecting device 5 are described in detail below.

[0022] In this embodiment: an installation device 4 is provided inside the connecting head 3, and the installation device 4 includes a connecting groove 41 and a connecting ring 43. The connecting groove 41 is opened inside the connecting head 3, and the connecting ring 43 is arranged inside the connecting groove 41. A positioning groove 42 is opened inside the connecting groove 41, and a pulling hole 44 is opened inside the connecting ring 43. A positioning plate 45 is slidably connected to the inside of the pulling hole 44.

[0023] Specifically, one end of the positioning plate 45 is located inside the positioning slot 42 and is clamped therein, and one end of the positioning plate 45 away from the positioning slot 42 is fixedly connected to a pull rod 46 .

[0024] In this embodiment, by arranging the adaptation of the positioning plate 45 and the positioning groove 42, the connecting ring 43 can be tightly combined, thereby reducing the difficulty of quickly installing the connecting ring 43 inside the device when the device is in use.

[0025] Specifically, a spring 48 is sleeved and connected to the surface of the pull rod 46. The two ends of the spring 48 are respectively located on the surface of the positioning plate 45 and fixedly connected inside the pulling hole 44. The spring 48 is provided to facilitate the positioning plate 45 to apply a reset elastic force.

[0026] Specifically, one end of the pull rod 46 away from the positioning plate 45 is fixedly connected to a pull handle 47 . The pull handle 47 is provided to facilitate the movement of the pull rod 46 .

[0027] In this embodiment: a connecting device 5 is provided on the surface of the connecting ring 43, and the connecting device 5 includes a groove 51 and a rubber pad 52. The groove 51 is opened on the surface of the connecting ring 43, and the rubber pad 52 is arranged inside the groove 51. A clamping column 55 is fixedly connected to the inside of the groove 51, and a clamping groove 54 is opened on the side of the rubber pad 52 close to the groove 51.

[0028] In this embodiment, by providing a connection between the clamping column 55 and the clamping groove 54 , the rubber pad 52 can be connected to the connecting ring 43 , thereby reducing the difficulty in installing the rubber pad 52 when the device is in use.

[0029] Specifically, the clamping column 55 is located inside the clamping groove 54 and is clamped. The end of the rubber pad 52 away from the groove 51 is provided with a contact groove 53 .

[0030] Working principle: When the equipment is in use, the user pulls the handle 47, and when the handle 47 moves, the pull rod 46 moves. When the pull rod 46 moves, it drives the positioning plate 45 to move. When the positioning plate 45 moves, it drives the spring 48 to displace and deform to generate elastic force, and then the positioning plate 45 disengages from the inside of the positioning groove 42, and then the connecting ring 43 loses its restraint, and then the connecting ring 43 is pulled out of the inside of the connecting groove 41. By setting the installation device 4, the connecting ring 43 is effectively installed and positioned, which plays a role in firmly positioning the connecting ring 43 and reduces the equipment in use. Generally, equipment uses sealant to connect the rubber pad 52 to the equipment. Long-term use of the sealant is prone to debonding. At the same time, when the rubber pad 52 needs to be replaced, special tools are required, which makes it difficult for maintenance personnel to quickly replace it. This installation device 4 quickly installs the connecting ring 43 to the inside of the equipment through the connecting ring 43, the positioning plate 45 and the spring 48, which greatly improves the installation efficiency of the equipment and improves the efficiency of the maintenance personnel's work.

[0031] When the device is in use, the user combines the rubber pad 52 with the surface of the groove 51, and then presses the rubber pad 52 to combine the clamping column 55 with the inside of the clamping groove 54 for installation. By providing the connecting device 5, the rubber pad 52 and the connecting ring 43 are effectively installed and connected, which plays a role in quickly replacing the connection of the rubber pad 52, reducing the situation where the rubber pad 52 is difficult to connect with the connecting ring 43 when the device is in use, making the device difficult to replace and use. This connecting device 5 quickly combines the rubber pad 52 with the connecting ring 43 through the extrusion between the clamping column 55 and the clamping groove 54, thereby improving the practicality of the device.
