Description

Technical Field

[0001] The utility model relates to the technical field of municipal water supply and drainage pipelines. More specifically, it particularly relates to a pipeline connection structure for municipal water supply and drainage. Background Technique

[0002] Currently, in the field of pipeline connection, there are mainly two common connection methods. First, two pipelines can be docked by means of threaded connection. In this way, mutually matching threads are processed at the ends of the pipelines, enabling the two pipelines to be tightly screwed together to form a sealed and firm connection. Second, another common connection method is to use a connector. A connector is a specially designed pipe fitting, and its two ends usually also have threads for threaded connection with the ends of the pipelines. This connection method also relies on the tight fit of the threads to ensure the sealing and stability between the pipelines. However, in the threaded connection method, situations such as non - matching or thread damage may occur during use, resulting in the inability to connect the pipelines and the need for replacement.

[0003] The utility model patent with the publication number CN209458533U discloses a pipeline connection structure for municipal water supply and drainage, including a first pipeline and a second pipeline. Fixed circular grooves are provided on the outer surfaces of one ends of the first pipeline and the second pipeline. One ends of the first pipeline and the second pipeline are fixedly connected with fixing plates. A clamping groove is provided on one side of the fixing plate, and a clamping block is clamped inside the clamping groove. One end of the clamping block away from the clamping groove is fixedly connected with a support block. This structure is very troublesome to install and remove during use, increasing the workload of the staff and thus reducing the work efficiency. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figure 1 , Figure 2 shown, the pipe connection structure for municipal water supply and drainage in this embodiment is arranged between the first pipe 1 and the second pipe 2, and includes a first fixing component connected to the first pipe 1 and a second fixing component connected to the second pipe 2. Both the first fixing component and the second fixing component include a collar 3 and a fastening ring 4. The collar 3 is sleeved on the outer side of the first pipe 1 or the second pipe 2. The collar 3 is made of rubber material. The fastening ring 4 is sleeved on the outer side of the collar 3 and tightens the collar 3, thereby squeezing the collar 3. Since the collar 3 is made of rubber material, after the collar 3 is tightened and squeezed by the fastening ring 4, the collar 3 is fixed on the outer side of the first pipe 1 or the second pipe 2, and a sealing structure can be formed between the collar 3 and the outer wall of the first pipe 1 or the second pipe 2..

[0025] In this embodiment, the fastening ring 4 is a hose clamp, and the hose clamp can provide better fastening force and adjustability, making the connection structure more firm and reliable. The inner diameter of the collar 3 is adapted to the outer diameters of the first pipe 1 and the second pipe 2, so as to ensure the tight fit between the collar 3 and the pipe, and improve the sealing performance and stability.

[0026] In this embodiment, in combination with Figure 3 and Figure 4As shown in the figure, a first fastening groove 5 is provided on the outer side of the collar 3, and the fastening ring 4 is embedded in the first fastening groove 5. This design can ensure the stability and reliability of the fastening ring 4 on the collar 3. Preferably, a second fastening groove 6 is also provided on the outer side of the collar 3. The second fastening groove 6 is located outside the first fastening groove 5, and the fastening ring 4 is also embedded in the second fastening groove 6. This double-fastening design can further improve the stability and durability of the connection structure.

[0027] In this embodiment, limiting rings 8 are fixed on the outer sides of both the first pipe 1 and the second pipe 2. A limiting groove 9 adapted to the limiting ring 8 is provided on the inner side of the collar 3. The limiting groove 9 is located between the first fastening groove 5 and the second fastening groove 6. An opening 10 is axially provided from one side of the limiting groove 9 close to the second fastening groove 6 to the end of the collar 3 away from the connecting pipe 7. This design can ensure the precise positioning and stability of the collar 3 on the pipe, preventing the collar 3 from being disengaged from the first pipe 1 or the second pipe 2 under external force. Preferably, at least two openings 10 are distributed in a circular array form, so that it is easier to fit the collar 3 outside the first pipe 1 or the second pipe 2.

[0028] Specifically, in this embodiment, the cross-section of the collar 3 is in a mountain shape structure. Two openings 10 are axially provided from one side of the limiting groove 9 close to the second fastening groove 6 to the end of the collar 3 away from the connecting pipe 7, and the two openings 10 are symmetrically arranged.

[0029] In this embodiment, the ends of the first pipe 1 and the second pipe 2 close to each other are arranged at intervals. A connecting pipe 7 is provided between the first fixing component and the second fixing component. Both ends of the connecting pipe 7 are fixedly connected to the two collars 3, so that it is not necessary to require the ends of the first pipe 1 and the second pipe 2 close to each other to be fitted and aligned. Specifically, the connecting pipe 7 can be a flexible pipe or a corrugated pipe, so as to increase the flexibility and adaptability of the connecting pipe 7, enabling it to better adapt to the small displacements and vibrations between the pipes.

[0030] The working principle of the pipe connection structure for municipal water supply and drainage in this embodiment is:

[0031] The pipe connection structure for municipal water supply and drainage in this embodiment includes a first fixing component and a second fixing component respectively connected to the first pipe 1 and the second pipe 2. Both the first fixing component and the second fixing component include a collar 3 and a fastening ring 4. The collar 3 is made of rubber and sleeved on the outer side of the first pipe 1 or the second pipe 2. The fastening ring 4 is sleeved on the outer side of the collar 3 and tightens the collar 3, thereby squeezing the collar 3. Since the collar 3 is made of rubber, after being tightened and squeezed by the fastening ring 4, the collar 3 is fixed on the outer side of the first pipe 1 or the second pipe 2, and a sealing structure can be formed between the collar 3 and the outer wall of the first pipe 1 or the second pipe 2, making the installation and removal processes simpler and more convenient. While ensuring the connection effect, it is also convenient for installation and removal, reducing the working intensity of the staff, simplifying the working process, and having very good practicability.
