Description

Technical Field

[0001] This utility model relates to the field of pipe flange technology, and in particular to a modular building pipe module quick-connect flange assembly. Background Technology

[0002] A flange is a connector used to connect pipes. It is widely used in piping systems in construction, industry and other fields. It is usually made of materials such as iron, steel or plastic. Its main function is to connect pipes in a pipeline system and ensure the stability of the connection between two pipes. It is an indispensable and important component in a pipeline system.

[0003] However, the design of traditional flange assembly connection methods has obvious drawbacks. They usually require a large number of studs and nuts for connection and installation. The installation operation requires the use of auxiliary tools such as wrenches and sockets, and the installation steps are relatively cumbersome. It is not convenient to quickly connect two flanges, which is time-consuming and labor-intensive. To address these issues, we provide a modular building pipeline module quick-connect flange assembly. Utility Model Content

[0004] The problem this utility model aims to solve is to provide a modular building pipeline module quick-connect flange assembly. This assembly eliminates the method of connecting flanges with bolts and nuts. During installation, there is no need to use multiple auxiliary tools such as wrenches and sockets to quickly complete the connection between flanges, and the operation process is time-saving and labor-saving.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a modular building pipeline module quick-connect flange assembly, including a first flange and a second flange. The inner wall of the first flange is provided with three calibration grooves. Three calibration columns are fixedly connected to the side of the second flange near the first flange. Two connecting blocks are fixedly connected to the outer surface of the first flange. Two snap-fit ​​grooves are provided on the inner wall of each of the two connecting blocks. Two fixing blocks are fixedly connected to the outer surface of the second flange. Connecting components are installed on the side of each of the two fixing blocks near the first flange.

[0006] Preferably, in the above-mentioned modular building pipe module quick-connect flange assembly, the connecting assembly includes a connecting column, which is fixedly connected to the side of the fixing block near the first flange. The inner wall of the connecting column is slidably connected to two snap-fit ​​blocks, which are symmetrically distributed vertically and are adapted to snap-fit ​​grooves.

[0007] Preferably, in the above-mentioned modular building pipe module quick-connect flange assembly, a limiting plate is fixedly connected to the outer surface of the snap-fit ​​block, and a spring is fixedly connected between the limiting plate and the inner wall of the connecting column, with the spring sleeved on the outer surface of the snap-fit ​​block.

[0008] Preferably, in the above-mentioned modular building pipe module quick-connect flange assembly, the inner wall of the connecting column is threaded with a stud, one end of the stud located inside the connecting column is fixedly connected to a spreading round block, and the other end of the stud located outside the connecting column is fixedly connected to a handle.

[0009] Preferably, in the above-mentioned modular building pipe module quick-connect flange assembly, the three calibration slots and the three calibration columns are all triangularly distributed, and the three calibration slots are respectively adapted to the three calibration columns.

[0010] Preferably, in the above-mentioned modular building pipe module quick-connect flange assembly, a sealing groove is provided on the side of the first flange near the second flange, and a sealing gasket is installed and connected on the side of the second flange near the first flange, wherein the sealing gasket is adapted to the sealing groove.

[0011] The advantages and beneficial effects of this utility model are:

[0012] This invention utilizes the cooperation between a first flange, a second flange, a connecting block, a snap-fit ​​groove, and a connecting assembly. By rotating the handle, the stud pushes the expanding round block to gradually insert between the two snap-fit ​​blocks, causing the two snap-fit ​​blocks to overcome the spring force and move away from each other, snapping into the snap-fit ​​groove, thus completing the installation. The end of the snap-fit ​​block is beveled, and when it is snapped into the snap-fit ​​groove, the beveled surface first contacts the snap-fit ​​groove. As the snap-fit ​​block is continuously inserted, the first flange and the second flange can be gradually tightened together. This design eliminates the need for bolt and nut connections, and eliminates the need for wrenches, sockets, and other auxiliary tools, allowing for quick connection of the first flange and the second flange, saving time and effort in the operation.

[0013] This invention utilizes the cooperation between the calibration groove, calibration column, sealing gasket, and sealing groove to insert the three calibration columns on the second flange into the three calibration grooves on the inner wall of the first flange, thereby achieving rapid alignment of the first and second flanges and ensuring accurate positioning during connection. After the first and second flanges are connected, the sealing gasket will be inserted into the sealing groove, effectively improving the sealing performance of the first and second flanges after connection.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] like Figures 1 to 5 As shown, a modular building pipe module quick-connect flange assembly includes a first flange 1 and a second flange 2. The inner wall of the first flange 1 has three calibration grooves 3. The second flange 2 is fixedly connected to three calibration posts 4 near the side of the first flange 1. The outer surface of the first flange 1 is fixedly connected to two connecting blocks 7. The inner wall of each connecting block 7 has two snap-fit ​​grooves 8. The outer surface of the second flange 2 is fixedly connected to two fixing blocks 5. The two fixing blocks 5 are each equipped with a connecting component 6 near the side of the first flange 1.

[0022] All three calibration slots 3 are cylindrical grooves, and all three calibration posts 4 are cylindrical protrusions. The positions and shapes of the three calibration slots 3 and the three calibration posts 4 correspond to each other. The cooperation between the two can realize the rapid positioning of the first flange 1 and the second flange 2 and prevent misalignment during connection. The two connecting blocks 7 are symmetrically distributed and correspond to the positions of the two fixing blocks 5. Two snap-fit ​​grooves 8 are opened on the inner wall of the connecting block 7 and are distributed vertically. Through the cooperation of the connecting block 7, the snap-fit ​​grooves 8 and the connecting assembly 6, the rapid connection between the first flange 1 and the second flange 2 can be realized.

[0023] The connecting assembly 6 includes a connecting post 601, which is fixedly connected to the side of the fixing block 5 near the first flange 1. Two snap-fit ​​blocks 602 are slidably connected to the inner wall of the connecting post 601. The two snap-fit ​​blocks 602 are symmetrically distributed vertically, and the snap-fit ​​blocks 602 are adapted to the snap-fit ​​groove 8.

[0024] The connecting column 601 has an internal mounting groove to provide mounting space for other parts. The two snap-fit ​​blocks 602 are located inside the mounting groove in the connecting column 601 at their closest ends, and outside the connecting column 601 at their furthest ends. When the snap-fit ​​block 602 is snapped into the snap-fit ​​groove 8 at its outer end, the connection and fixation between the first flange 1 and the second flange 2 can be achieved.

[0025] A limiting plate 603 is fixedly connected to the outer surface of the snap-fit ​​block 602. A spring 604 is fixedly connected between the limiting plate 603 and the inner wall of the connecting column 601. The spring 604 is sleeved on the outer surface of the snap-fit ​​block 602.

[0026] The limiting plate 603 is used to limit the sliding stroke of the snap-fit ​​block 602 to prevent it from disengaging from the connecting post 601. When the snap-fit ​​block 602 is snapped into the snap-fit ​​groove 8, the limiting plate 603 can compress the spring 604. Under normal conditions, the spring 604 keeps the snap-fit ​​block 602 in the mounting groove of the connecting post 601. When compressed, the snap-fit ​​block 602 can extend out of the connecting post 601 and snap into the snap-fit ​​groove 8. It can also provide elastic force for the snap-fit ​​block 602 to reset later.

[0027] The inner wall of the connecting post 601 is threaded with a stud 605. One end of the stud 605 located inside the connecting post 601 is fixedly connected to a spreading block 606, and the other end of the stud 605 located outside the connecting post 601 is fixedly connected to a throttle 607.

[0028] When the throttle 607 is turned, the stud 605 can rotate, which drives the spreading block 606 to move and gradually insert between the two locking blocks 602, squeezing the two locking blocks 602 so that they can slide against the elastic force of the spring 604 and lock into the locking groove 8.

[0029] The three calibration slots 3 and the three calibration columns 4 are all arranged in a triangular pattern, and the three calibration slots 3 are respectively matched with the three calibration columns 4.

[0030] The triangular arrangement of the three calibration slots 3 and the three calibration posts 4 allows the first flange 1 and the second flange 2 to be quickly aligned. Furthermore, when the three calibration slots 3 are inserted into the three calibration posts 4 respectively, they form a positioning constraint, ensuring precise alignment when the first flange 1 and the second flange 2 are connected.

[0031] A sealing groove 9 is provided on the side of the first flange 1 near the second flange 2, and a sealing gasket 10 is installed and connected on the side of the second flange 2 near the first flange 1. The sealing gasket 10 is adapted to the sealing groove 9.

[0032] The sealing groove 9 is an annular groove, and the sealing gasket 10 is made of elastic material and its shape is adapted to the sealing groove 9. When the first flange 1 is connected to the second flange 2, the sealing gasket 10 can be embedded in the sealing groove 9, which effectively improves the sealing performance after the first flange 1 and the second flange 2 are connected.

[0033] Working principle: In use, firstly, the three calibration posts 4 distributed in a triangle on the second flange 2 are inserted into the three calibration slots 3 on the inner wall of the first flange 1. Utilizing the fit between the calibration slots 3 and the calibration posts 4, the first flange 1 and the second flange 2 are quickly and accurately positioned. Simultaneously, the connecting posts 601 in the connecting components 6 installed on the sides of the two fixing blocks 5 are inserted into the two connecting blocks 7. At this time, the locking block 602 is located inside the connecting post 601. Then, the handle 607 in the connecting component 6 is rotated, causing the stud 605 to rotate and pushing the expanding block open. Insert 606 between the two snap-fit ​​blocks 602, so that the two snap-fit ​​blocks 602 are far apart and slide outward of the connecting post 601 against the elastic force of the spring 604. Then, snap into the snap-fit ​​groove 8. Since the end of the snap-fit ​​block 602 is beveled, the beveled surface first contacts the snap-fit ​​groove 8 when snapping into it. As the snap-fit ​​block 602 is continuously inserted, the first flange 1 and the second flange 2 are gradually tightened and connected, thus completing the installation. At this time, the sealing gasket 10 on the second flange 2 will be embedded in the sealing groove 9 of the first flange 1, enhancing the sealing of the connection.
