Description

Technical Field

[0001] This utility model relates to the field of flange technology, specifically to a flange that is easy to install. Background Technology

[0002] Flanges are common components in pipeline connections. They are disc-shaped parts, usually used in pairs. In pipeline engineering, flanges are mainly used for connections between pipes and between pipes and equipment. By bolting the flanges together and adding gaskets, reliable connections and good seals can be achieved in the pipeline system, thus ensuring the normal transport of fluid media. Flanges are widely used in pipeline systems in many industries such as petrochemicals, power, and water supply and drainage, and are an indispensable and important component for ensuring the stable operation of pipeline systems.

[0003] Existing flanges typically use bolts inserted through bolt holes in the flange plate, secured by tightening nuts. This process is cumbersome, with complex bolt insertion and tightening operations leading to low installation efficiency and difficult disassembly. When pipeline system maintenance or component replacement is required, bolts may corrode or become stuck after prolonged use, further complicating disassembly and consuming significant time and labor costs. Therefore, this paper proposes an easier-to-install flange to address the aforementioned problems. Utility Model Content

[0004] To solve the aforementioned technical problems, this technical solution provides an easy-to-install flange. This solution addresses the issues raised in the background section regarding the complexity of flange connection, low installation efficiency, and the significant time and labor costs involved.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An easy-to-install flange, comprising:

[0007] The first connecting pipe has a first flange fixedly connected to its end. The outer surface of the first flange has a rotating groove. The inside of the first flange is rotatably connected to a jack. The end of the jack away from the first flange has several through notches and several first insertion holes. The outer surface of the jack is fixedly connected to a rotating handle. The outer surface of the rotating handle is slidably connected to the inside of the rotating groove.

[0008] The second connecting pipe has a second flange fixedly connected to its end. The second flange has a groove inside. Several protruding ridges are fixedly connected to the edge of the second flange on the side away from the groove. Several second insertion holes are opened through the outer surface of the second flange on the side close to the second connecting pipe.

[0009] A locking assembly, which is fixedly connected to a second flange.

[0010] Preferably, the plurality of notches and protrusions correspond one-to-one.

[0011] Preferably, the locking assembly includes a rod slidably connected to the inner surface of the second socket, a sleeve slidably connected to the outer surface of the rod, a limiting plate fixedly connected to the end of the rod located inside the sleeve, the limiting plate being slidably disposed inside the sleeve, a connecting rod fixedly connected to the side of the limiting plate away from the rod, and a pull plate fixedly connected to the other end of the connecting rod.

[0012] Preferably, a damping spring is fixedly connected between the limiting plate and the pull plate.

[0013] Preferably, the locking assembly is fixedly connected to a movable tube that slides on the outer surface of the second connecting pipe at one end away from the second flange.

[0014] Compared with the prior art, this utility model provides a flange that is easy to install and has the following advantages:

[0015] This utility model, by setting up a quick-connect component and adopting a connection method of cams and slots, replaces the traditional bolt and nut connection. It eliminates the need to insert and tighten bolts one by one, and the installation and disassembly process does not require significant displacement of the flange body, reducing the difficulty of installation and disassembly, shortening the installation and disassembly time, and significantly improving work efficiency.

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0025] Reference Figures 1-6 As shown, an easy-to-install flange includes:

[0026] The first connecting pipe 1 has a first flange 3 fixedly connected to its end. The outer surface of the first flange 3 has a rotating groove 301. The inside of the first flange 3 is rotatably connected to a chuck 5. The end of the chuck 5 away from the first flange 3 has several through notches 7 and several first insertion holes 8. The outer surface of the chuck 5 is fixedly connected to a handle 6. The outer surface of the handle 6 is slidably connected to the inner side of the rotating groove 301.

[0027] The second connecting pipe 2 has a second flange 4 fixedly connected to its end. The second flange 4 has a groove 9 inside. Several protruding ridges 10 are fixedly connected to the edge of the second flange 4 on the side away from the groove 9. Several second insertion holes 11 are opened through the outer surface of the second flange 4 on the side close to the second connecting pipe 2.

[0028] Locking component 12 is fixedly connected to the second flange 4.

[0029] As an example of this utility model, multiple notches 7 and protrusions 10 correspond one-to-one. The notches 7 on the cassette 5 are aligned with the protrusions 10, thereby inserting the protruding cassette 5 into the slot 9. Then, the handle 6 on the cassette 5 is turned, and the rotation of the cassette 5 makes the first insertion hole 8 correspond to the second insertion hole 11.

[0030] As an example of this utility model, the locking assembly 12 includes a rod 1201 slidably connected to the inner surface of the second insertion hole 11, a sleeve 1205 slidably connected to the outer surface of the rod 1201, a limiting plate 1202 fixedly connected to the end of the rod 1201 located inside the sleeve 1205, the limiting plate 1202 being slidably disposed inside the sleeve 1205, a connecting rod 1203 fixedly connected to the side of the limiting plate 1202 away from the rod 1201, and the other end of the connecting rod 1203 being fixedly connected to the other end of the rod 1203. A pull plate 1204 is fixedly connected, and a damping spring 1206 is fixedly connected between the limiting plate 1202 and the pull plate 1204. During installation, the retaining wheel 5 abuts against the insertion rod 1201, and the damping spring 1206 shortens under pressure. As the retaining wheel 5 rotates, the first insertion hole 8 aligns with the second insertion hole 11, and the insertion rod 1201 enters the first insertion hole 8 under the action of the damping spring 1206. No manual intervention is required, which reduces the difficulty of installation, shortens the installation time, and significantly improves the installation efficiency.

[0031] As an example of this utility model, the locking component 12 is fixedly connected to a movable tube 13 that slides on the outer surface of the second connecting pipe 2 at one end away from the second flange 4. When the flange is disassembled, pulling the movable tube 13 will pull all the inserts 1201 out of the first insertion hole 8. Turning the handle 6 will make the notch 7 correspond to the convex ridge 10, and the jack 5 will be pulled out of the slot 9 to complete the disassembly.

[0032] Working principle: When using this utility model, firstly, align the notch 7 on the locating wheel 5 with the protruding ridge 10, thereby inserting the protruding locating wheel 5 into the slot 9. At this time, the locating wheel 5 abuts against the insertion rod 1201, and the damping spring 1206 shortens under pressure. Then, turn the handle 6 on the locating wheel 5. The rotation of the locating wheel 5 aligns the first insertion hole 8 with the second insertion hole 11. The insertion rod 1201 enters the first insertion hole 8 under the action of the damping spring 1206, completing the installation. When disassembling the flange, pull the moving tube 13 to pull all the insertion rods 1201 out of the first insertion hole 8. Turn the handle 6 to rotate the locating wheel 5. When the notch 7 aligns with the protruding ridge 10, pull the locating wheel 5 out of the slot 9 to complete the disassembly.
