Description

Technical Field

[0001] This utility model relates to the technical field of connection mechanisms for water supply and drainage pipes of different diameters, specifically a connection mechanism for water supply and drainage pipes of different diameters. Background Technology

[0002] Water supply and drainage pipelines are facilities used in water transmission systems for transportation and discharge. They can be used to transport clean water to meet the water needs of domestic and industrial use, as well as to collect and transport sewage, which has a significant impact on the quality of life and the urban environment.

[0003] A search revealed Chinese patent CN220396835U, which discloses a connection mechanism for water supply and drainage pipes of different diameters. This mechanism includes a main connecting pipe and a main pipe. A sealing assembly is installed on the outside of the main connecting pipe. The sealing assembly includes auxiliary connecting pipes fixedly installed on both sides of the main connecting pipe. The outer surface of each auxiliary connecting pipe has a threaded groove, and a movable ring is threaded onto its outer surface. A spring is fixedly connected to the side of the movable ring away from the main connecting pipe, and a sealing gasket is fixedly connected to the side of the fixed ring away from the spring. A multi-stage telescopic sleeve is fixedly installed at the bottom of the main connecting pipe, and a base plate is fixedly connected to the bottom of the multi-stage telescopic sleeve. This water supply and drainage pipe connection mechanism, by incorporating the sealing assembly, allows the fixed ring to move towards the pipe simply by rotating the movable ring, ultimately causing the sealing gasket to abut against the top of the pipe, effectively preventing leakage and improving sealing performance.

[0004] The above solution utilizes the cooperation between the movable ring, spring, and sealing gasket. When connecting the pipes, rotating the movable ring can push the sealing gasket to move. At this time, the threaded connection between the main connecting pipe and the pipe, as well as the compression seal of the sealing gasket, can tighten the connection position and reduce leakage. However, in the above solution, both auxiliary connecting pipes are threaded to the pipe. When one connecting pipe is rotated, the auxiliary connecting pipe on the other side will rotate as well. At this time, it is difficult to adjust the length and position of the auxiliary connecting pipes on both sides. The connection position and length need to be determined first before installation, which is more troublesome.

[0005] To address these issues, we provide connection mechanisms for water supply and drainage pipes of different diameters. Utility Model Content

[0006] 1) Technical problems to be solved

[0007] This utility model proposes a connection mechanism for water supply and drainage pipes of different diameters. By cooperating between the fixed pipe and the fixed ring, it solves the problem of difficulty in adjusting the length and position of the auxiliary connecting pipes on both sides.

[0008] (ii) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a water supply and drainage pipe connection mechanism with different diameters, comprising a connecting pipe one and a connecting pipe two, wherein a fixing pipe is fixedly installed at one end of the connecting pipe one, a fixing ring is threadedly connected to the outside of the fixing pipe, and a limit ring is slidably connected inside the fixing pipe;

[0010] One end of each of the connecting pipes is fixedly installed with a connecting ring 1. The outside of the connecting ring 1 is detachably connected to the connecting ring 2. An installation pipe is fixedly installed inside the connecting ring 2. A main pipe is threadedly connected to the outer surface of the installation pipe. A positioning ring is fixedly installed on the outer surface of the installation pipe.

[0011] Furthermore, the outer surface of the fixed tube is slidably connected to the inside of the second connecting tube, and a support ring is fixedly installed on the inner wall of the second connecting tube. The outer surface of the support ring is fixedly installed with the outer surface of the limiting ring.

[0012] Furthermore, a fixing groove is provided inside the fixing tube, and a sealing ring is installed inside the fixing groove. The outer surface of the fixing ring is in contact with the outer surface of the sealing ring.

[0013] Furthermore, a second sealing ring is installed on the outside of the positioning ring, and the outer surface of the second sealing ring is in contact with one side of the main pipe.

[0014] Furthermore, the first connecting pipe and the second connecting pipe are arranged in opposite directions, and the first connecting ring and the second connecting ring are also arranged in opposite directions outside the first connecting pipe and the second connecting pipe.

[0015] Furthermore, both connecting pipe one and connecting pipe two are fitted with mounting rings, and a support rod is hinged inside the mounting ring. A base plate is rotatably connected to the outer surface of the support rod.

[0016] (iii) Beneficial effects:

[0017] Compared with existing technologies, this water supply and drainage pipe diameter connection mechanism has the following advantages:

[0018] I. This water supply and drainage pipe diameter connection mechanism, through the cooperation between the fixed pipe and the fixed ring, allows for the connection of the main pipe. First, connecting pipe one and connecting pipe two are placed at the connection position of the adjacent main pipe. At this time, under the action of the fixed pipe, connecting pipe one and connecting pipe two on both sides can rotate independently without the need for special calculation and adjustment of the length on both sides. After the installation pipes on both sides are installed, the fixed ring is rotated to seal the outside of the fixed pipe. At this time, the main pipes on both sides can be quickly connected and installed without the need to first determine the length of the installation pipes on both sides before installation. This realizes the function of installing and fixing the pipes and is conducive to adjusting the length and position of the auxiliary connecting pipes on both sides.

[0019] Second, this water supply and drainage pipe diameter connection mechanism, by setting up components such as a limiting ring, allows the fixing ring to be rotated after connecting pipe one and connecting pipe two are connected to the installation pipes on both sides. At this time, the fixing ring squeezes the sealing ring one, which can seal the connection between the fixing pipe and connecting pipe two. The limiting ring can position the fixing pipe. At this time, the connection between connecting pipe two and the fixing pipe will not be separated, thus improving the stability of the connection between connecting pipe one and connecting pipe two through the fixing pipe.

[0026] 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.

[0027] like Figure 1 - Figure 4As shown, this utility model provides a technical solution: a water supply and drainage pipe connection mechanism with different diameters, including a connecting pipe 1 and a connecting pipe 2, which are arranged in opposite directions. A fixing pipe 3 is fixedly installed at one end of the connecting pipe 1. The outer surface of the fixing pipe 3 is slidably connected to the inside of the connecting pipe 2. The outer diameter of the fixing pipe 3 is the same as the inner diameter of the connecting pipe 2. The fixing pipe 3 can connect the inside of the connecting pipe 1 and the connecting pipe 2. A limiting ring 5 is slidably connected inside the fixing pipe 3. A support ring 11 is fixedly installed on the inner wall of the connecting pipe 2. The outer surface of the support ring 11 is fixedly installed to the outer surface of the limiting ring 5. The cross-section of the support ring 11 is an L-shaped structure. After the limiting ring 5 is connected to the support ring 11, a groove is formed inside. One end of the fixing pipe 3 contacts the inside of the groove. At this time, the limiting ring 5 can fix and limit the fixing pipe 3. When the connecting pipe 1 and the connecting pipe 2 are connected, they can form a connected whole.

[0028] The fixed pipe 3 is externally threaded with a fixing ring 4. The fixed pipe 3 has a fixing groove 12 inside, and a sealing ring 13 is installed inside the fixing groove 12. The outer surface of the fixing ring 4 is in contact with the outer surface of the sealing ring 13. When the connecting pipe 1 and the connecting pipe 2 are connected to the external pipe, the fixing ring 4 is rotated. When the fixing ring 4 is rotated through the threaded connection, it can approach one end of the connecting pipe 2. At this time, the fixing ring 4 can squeeze the sealing ring 13. By squeezing the sealing ring 13, the fixing pipe 3 and the connecting pipe 2 can be sealed. When the connecting pipe 1 and the connecting pipe 2 are fixed, the connection position can be sealed.

[0029] The outer surface of the mounting pipe 8 is threaded with a main pipe 9. One end of both the connecting pipe 1 and the connecting pipe 2 is fixedly mounted with a connecting ring 6. The outside of the connecting ring 1 is detachably connected to a connecting ring 7. The mounting pipe 8 is fixedly mounted inside the connecting ring 2. The connecting ring 1 and the connecting ring 2 are arranged in opposite directions outside the connecting pipe 1 and the connecting pipe 2. The connecting ring 2 and the mounting pipe 8 are set as a standardized module. Different sizes of mounting pipe 8 are selected according to the diameter of different main pipes 9. Then, the mounting pipe 8 is connected to the connecting pipe 1 and the connecting pipe 2 through the connecting ring 2. Different diameter mounting pipes 8 can be selected according to different sizes of main pipes 9, which facilitates the connection of pipes with different diameters.

[0030] A positioning ring 10 is fixedly installed on the outer surface of the mounting tube 8. A sealing ring 14 is installed on the outside of the positioning ring 10. The outer surface of the sealing ring 14 contacts one side of the main tube 9. When connected to the main tube 9, the mounting tube 8 is rotated. At this time, the positioning ring 10 and the sealing ring 14 will approach one end of the main tube 9. At this time, the mounting tube 8 can automatically seal the outside of the main tube 9 when it is installed.

[0031] Both connecting pipe 1 and connecting pipe 2 are fitted with mounting rings 15. A support rod 16 is hinged inside the mounting ring 15. A base plate 17 is rotatably connected to the outer surface of the support rod 16. The mounting ring 15 does not rotate with connecting pipe 1 and connecting pipe 2, which facilitates installation and use. After connecting pipe 1 and connecting pipe 2 are installed, the angle between the two sets of support rods 16 is adjusted. At this time, the base plate 17 is fixed to the ground and can provide auxiliary support for connecting pipe 1 and connecting pipe 2.

[0032] Working principle: When connecting the main pipe 9, the main pipe 9 is first connected through the installation pipe 8. By rotating the installation pipe 8, the sealing ring 14 can be squeezed. At this time, the sealing ring 14 can seal the outside of the main pipe 9. When the installation pipe 8 rotates, the connecting pipe 1 and the connecting pipe 2 can rotate separately under the action of the fixing pipe 3. Different sizes of installation pipe 8 can be selected according to the different diameters of the main pipe 9. After connecting the installation pipe 8, the fixing ring 4 is rotated. After the fixing ring 4 rotates, it squeezes the sealing ring 13 to seal the connection position between the fixing pipe 3 and the connecting pipe 2.
