Description

Technical Field

[0001] This utility model relates to a municipal pipeline connection structure. Background Technology

[0002] Municipal pipelines refer to various functional pipelines laid underground in urban public areas, mainly used to meet the needs of urban water supply and drainage, power supply, communication transmission, etc. These pipeline systems are an important part of urban infrastructure.

[0003] Most common pipes are of fixed length. When connecting two pipes together, the common operations are welding and flange connection. Welding is difficult to disassemble and repair, increasing the cost of later maintenance. Flange connection usually requires the flanges to be installed at both ends of the pipe by welding, bolting or other methods. When the pipe is damaged and needs to be replaced, the flange on the pipe may be discarded or need to be disassembled and reused.

[0004] Therefore, how to reduce the number of parts connected to the pipeline so as not to waste additional resources when discarding damaged pipelines has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a municipal pipeline connection structure that connects two pipelines by fitting a connector over the first pipeline and the second pipeline.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a first pipe, a second pipe, and a connector located between the first pipe and the second pipe. The axial directions of both the first pipe and the second pipe extend to the left and right. It also includes a first sealing ring and a second sealing ring. The connector is sleeve-shaped and located on the outer periphery of the first pipe and the second pipe. The left side of the connector is fastened to the first pipe, and the right side is fastened to the second pipe. The first sealing ring is located between the first pipe and the connector, and the second sealing ring is located between the second pipe and the connector.

[0007] The present invention is further configured such that: the connector includes an internal mounting groove, and the connector is provided with a plurality of limiting blocks protruding radially inward on the left side of the mounting groove, and the first pipe is provided with a limiting slot corresponding to each limiting block.

[0008] The present invention is further configured such that: the first pipe also includes a connecting section located on the right side of each limiting slot, and the left side of the connecting section abuts against each limiting block.

[0009] The present invention is further configured such that: the connecting section is provided with a plurality of insert rods protruding circumferentially to the right, and the second pipe is provided with an insertion groove corresponding to each insert rod.

[0010] The present invention is further configured such that: the connector is circumferentially rotatably mounted with a plurality of fixing plates on the right side of the mounting groove, each fixing plate including a limiting section for inserting the second pipe, and the connector is slidably mounted with a mating block for inserting the fixing plate corresponding to each fixing plate.

[0011] The present invention is further configured to include a mating spring with one end fixed to the corresponding mating block and the other end fixed to the connector, and a post for inserting each mating spring. Each post is fixedly mounted with a contact plate. The connector is provided with a sliding groove corresponding to each contact plate. The connector also includes a fixing section fixed to each mating spring. One end of each contact plate abuts against the corresponding fixing section.

[0012] The present invention is further configured such that: each fixed plate is provided with a mating slot for inserting mating blocks, each mating block is away from the guide surface of the corresponding mating spring side, and each guide surface is inclined.

[0013] By adopting the above technical solution, and by setting a sleeve-shaped connector between the first pipe and the second pipe, and setting a first sealing ring and a second sealing ring between the connector and the first and second pipes respectively, a good sealing performance at the pipe connection is achieved. This structure is not only easy to install and disassemble, but also effectively improves the overall stability and sealing performance of the pipeline system. Furthermore, since the left side of the connector is engaged with the first pipe and the right side is engaged with the second pipe, compared with pipe connections through welding, the first pipe and the second pipe can be separated by removing the connector. For two pipes connected by flanges, when the damaged pipe is removed and discarded, the flange will not be lost and there is no need to remove the flange separately, thus ensuring that the process of discarding the damaged pipe does not result in the loss of additional parts.

[0028] 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.

[0029] like Figures 1-6As shown, this utility model discloses a municipal pipeline connection structure, including a first pipeline 1, a second pipeline 2, and a connector 3 located between the first pipeline 1 and the second pipeline 2. The first pipeline 1 and the second pipeline 2 both extend axially to the left and right. The connector 3 is inserted between the first pipeline 1 and the second pipeline 2 to fix it to the two pipelines, thus connecting them. The structure also includes a first sealing ring 4 and a second sealing ring 5. The connector 3 is sleeve-shaped and located on the outer periphery of the first pipeline 1 and the second pipeline 2. The left side of the connector 3 is fastened to the first pipeline 1, and the right side is fastened to the second pipeline 2. The first sealing ring 4 is located between the first pipeline 1 and the connector 3, and the second sealing ring 5 is located between the second pipeline 2 and the connector 3. A sleeve-shaped connector 3 is installed between the first pipe 1 and the second pipe 2, and a first sealing ring 4 and a second sealing ring 5 are respectively installed between the connector 3 and the first and second pipes 2, respectively, to achieve good sealing performance at the pipe connection. This structure not only facilitates installation and disassembly, but also effectively improves the overall stability and sealing of the pipeline system. Since the left side of the connector 3 is fastened to the first pipe 1 and the right side is fastened to the second pipe 2, compared with the pipe connection by welding, the first pipe 1 and the second pipe 2 can be separated by removing the connector 3. For the two pipes connected by flanges, the flange will not be lost when the damaged pipe is removed and discarded, and there is no need to remove the flange separately. Thus, the process of discarding the damaged pipe will not result in the loss of additional parts.

[0030] The connector 3 includes an internal mounting groove 31. Several limiting blocks 32 protrude radially inward from the left side of the mounting groove 31. Each limiting block 32 corresponds to a limiting slot 11 on the first pipe 1. When the first pipe 1 is inserted into the mounting groove 31 of the connector 3, the protruding limiting blocks 32 fall into their respective limiting slots 11 on the first pipe 1, preventing the first pipe 1 from rotating radially or moving axially relative to the connector 3. This allows the first pipe 1 to... Pipe 1 is connected to connector 3. Because the pipe is made of flexible material, hydraulic pressure can apply pressure to the first pipe 1 during fluid transmission, so that the first pipe 1 can fit more closely to the inner wall of connector 3 without the separation of the limiting plug 32 and the limiting slot 11. Before it is removed, the liquid transmission needs to be cut off. At this time, as the liquid leaves the first pipe 1, the hollow first pipe 1 can deform radially inward, so that each limiting plug 32 separates from the limiting slot 11, and then the first pipe 1 can be removed from connector 3.

[0031] Preferably, the first pipe 1 further includes a connecting section 12 located to the right of each limiting slot 11. The left side of the connecting section 12 abuts against each limiting plug 32. The connecting section 12 located to the right of the limiting slot 11 is provided on the first pipe 1, and the left side of the connecting section 12 abuts against the limiting plug 32. Therefore, after the assembly is completed, if an axial force is applied to the first pipe 1 to the left, in addition to the action of the limiting plug 32 and the limiting slot 11, the connecting section 12 moving to the left needs to pass over each limiting plug 32 to be able to disengage from the connector 3, thereby further improving the connection stability between the first pipe 1 and the connector 3. When the first pipe 1 is inserted into the connector 3, the connecting section 12 needs to deform radially inward so as to pass over each limiting plug 32. At the same time as the limiting plug 32 and the limiting slot 11 are engaged, the connecting section 12 is located to the right of each limiting plug 32.

[0032] The connecting section 12 has several insert rods 121 protruding circumferentially to the right. The second pipe 2 has insertion slots 21 corresponding to each insert rod 121. Since the insert rods 121 on the connecting section 12 will be inserted into the insertion slots 21 of the second pipe 2, after the assembly of the first pipe 1 and the connector 3 is completed, the second pipe 2 is then inserted into the other end of the mounting slot 31 through the connector 3. At this time, after each insert rod 121 completes its cooperation with the insertion slot 21, the relative positions of the first pipe 1 and the second pipe 2 are determined, and the two cannot rotate relative to each other, thus facilitating the connection between the connector 3 and the second pipe 2.

[0033] The connector 3 is circumferentially mounted with several fixing plates 33 on the right side of the mounting groove 31. Each fixing plate 33 includes a limiting section 331 for inserting the second pipe 2. The connector 3 has a corresponding mating block 34 for inserting the fixing plate 33. Since each fixing plate 33 is rotatably mounted on the connector 3 and the limiting section 331 will insert the second pipe 2, before the second pipe 2 is inserted into the connector 3 to determine its relative position with the first pipe 1, the fixing plates 33 are rotated radially outward to disengage the limiting sections 331 from the interior of the connector 3. When the second pipe 2 is inserted and cannot rotate relative to the first pipe 1, the fixing plates 33 rotate radially inward toward the second pipe 2. At this time, the limiting segments 331 of each fixing plate 33 fall into different positions of the second pipe 2, so that the second pipe 2 cannot be separated from the connector 3 under the action of each limiting segment 331. The determination of the relative position of the connector 3 and the second pipe 2 can facilitate the sliding of each mating plug 34. When each mating plug 34 is inserted into the fixing plate 33, the connection between the connector 3 and the second pipe 2 is completed, so that they will not separate without the action of external force.

[0034] The system also includes a mating spring 6, one end of which is fixed to the corresponding mating block 34 and the other end of which is fixed to the connector 3 by welding or other means, and inserts 7 for inserting each mating spring 6. Each insert 7 is fixedly mounted with a contact plate 71 by welding, integral molding or other means. The connector 3 is provided with a sliding groove 35 corresponding to each contact plate 71. The connector 3 also includes a fixing section 36 fixed to each mating spring 6. One end of each contact plate 71 abuts against the corresponding fixing section 36. Since the connector 3 is also slidably mounted with inserts 7, when the second pipe 2 needs to be removed, the inserts 7 can be moved by applying force to the contact plate 71, thereby separating each limiting block 32 from the mounting plate. At this time, the mating spring 6 is compressed and can rotate radially outward to fix itself. Plate 33 then moves axially to the right to separate the second pipe 2 from the connector 3. After the second pipe 2 is inserted into the connector 3, the fixing plate 33 is rotated radially inward so that after each limiting segment 331 inserts the second pipe 2, the force on the contact plate 71 is released. At this time, the force of the spring 6 drives the mating block 34 to be inserted into the fixing plate 33. Without the action of external force, the fixing plate 33 cannot rotate due to the restriction of the mating block 34, and thus cannot separate the limiting segment 331 from the second pipe 2. This allows the second pipe 2 to be stably connected to the connector 3. In addition, the presence of the fixing segment 36 can limit the movement path of the insert 7, and with the help of the spring 6, it can be compressed or reset between the limiting block 32 and the fixing plate 33.

[0035] Preferably, each fixed plate 33 is provided with a mating slot 332 for inserting the mating block 34. Each mating block 34 is away from the guide surface 341 on the side of the corresponding mating spring 6. Each guide surface 341 is inclined. Since each guide surface 341 is inclined, during the process of sliding the insert post 7 and driving the mating block 34 to insert into the fixed plate 33, the presence of the guide surface 341 makes the mating block 34 trapezoidal, which facilitates the alignment of its insertion position with the fixed plate 33.

[0036] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
