[0002] A flange is a disc or ring-shaped connector with bolt holes, used to fix and connect pipes, equipment interfaces, valves and other components and ensure a seal. When connecting flanges to pipes of different specifications and types, conversion joints are often used.
[0003] When using adapters to convert flanges, traditional adapters involve directly inserting the flange adapter into the corresponding installation position and then securing it with adhesives. When the adapter needs replacement due to damage, the adhesive's curing process can cause the direct-insertion adapter to become excessively stuck to the flange, making it impossible to disassemble separately. Currently, the common method is to replace the entire flange and adapter. While this solves the immediate problem of inability to disassemble, the overall replacement is costly and wasteful of resources. Utility Model Content
[0004] The present invention aims to at least partially solve one of the technical problems in the above-mentioned technologies.
[0005] Therefore, one objective of this utility model is to propose a flange adapter. By adding a fixing structure to the outside of the flange adapter and reinforcing the pipe inserted into the flange adapter, it is not easy for the pipe to fall off during use.

One end of the first and second connecting flanges is respectively provided with an installation groove. The installation pipe is disposed in the installation groove, the connecting ring is disposed at one end of the installation pipe, the elastic plate is disposed on the outer wall of the connecting ring, the limiting plate is disposed on the elastic plate, the outer wall of the joint is provided with a slot, and the control component is disposed in the installation groove.
[0007] In addition, the flange conversion joint proposed above according to this utility model may also have the following additional technical features: Specifically, the control assembly includes a sleeve, an abutment block, a connecting post, and a control ring. The sleeve is fitted over the outside of the mounting tube, the abutment block is located at one end of the sleeve, the connecting post is connected to the other end of the sleeve, and the other end of the connecting post passes through the fixing cover and is connected to the control ring.

[0014] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0015] The flange adapter of this utility model is described below with reference to the accompanying drawings.
[0016] like Figures 1-5 As shown, the flange conversion joint of this utility model embodiment includes: a first connecting flange 1, a second connecting flange 2, a joint 3, and a fixing mechanism 4. The second connecting flange 2 is connected to one end of the first connecting flange 1, and the joint 3 is respectively disposed at the other end of the first connecting flange 1 and the second connecting flange 2. The fixing mechanism 4 includes an installation pipe 42, a connecting ring 43, an elastic plate 44, a limiting plate 45, a fixing cover 47, and a control component 48. The first connecting flange 1 and the second connecting flange 2 are respectively provided with an installation groove 41. The installation pipe 42 is disposed in the installation groove 41. The connecting ring 43 is disposed at one end of the installation pipe 42. The elastic plate 44 is disposed on the outer wall of the connecting ring 43. The limiting plate 45 is disposed on the elastic plate 44. The outer wall of the joint 3 is provided with a slot 46. The control component 48 is disposed in the installation groove 41.
[0017] Specifically, when a flange adapter is needed to connect the connector 3, the relevant personnel first insert the connector 3 into the first connecting flange 1 and the second connecting flange 2 respectively. At this time, the outer wall of the connector 3 will push the elastic plate 44 outward through the limiting plate 45. The elastic plate 44 accumulates elastic potential energy. Then, as the connector 3 is gradually inserted, the groove 46 on the outer wall of the connector 3 will gradually align with the limiting plate 45. When the groove 46 is aligned with the limiting plate 45, the elastic plate 44 springs back to its original position, thereby pushing the limiting plate 45 on the elastic plate 44 into the groove 46 to complete the fixation. Then, the first connecting flange 1 and the second connecting flange 2 are aligned and fastened with bolts to form a stable and reliable sealing structure between the first connecting flange 1 and the second connecting flange 2.
[0018] In one embodiment of this application, such as Figure 2 and Figure 4 As shown, the control component 48 includes a sleeve 481, an abutment block 482, a connecting post 483, and a control ring 484. The sleeve 481 is fitted over the outside of the mounting tube 42. The abutment block 482 is located at one end of the sleeve 481. The connecting post 483 is connected to the other end of the sleeve 481. The other end of the connecting post 483 passes through the fixing cover 47 and is connected to the control ring 484. A sealing ring 485 is provided in the mounting groove 41.
[0019] Specifically, when joint 3 is damaged, the relevant personnel will remove the bolts that fasten the first connecting flange 1 and the second connecting flange 2, thereby separating the first connecting flange 1 and the second connecting flange 2. Then, the relevant personnel will push joint 3 towards the corresponding flange. At this time, joint 3 moves forward, and the limiting plate 45 in the slot 46 will tilt upward due to the restriction of the elastic plate 44. Then, the relevant personnel will push the control ring 484, and the control ring 484 will push the sleeve through the connecting column 483. 481, and push the elastic plate 44 outward through the abutment block 482 on the sleeve 481. At this time, the elastic plate 44 accumulates elastic potential energy, thereby removing the raised limit plate 45 from the slot 46. Then, the connector 3 is removed and the control ring 484 is released. At this time, the elastic plate 44, which has lost the compression, rebounds and releases elastic potential energy. During the rebound process, the outer wall of the elastic plate 44 will squeeze the abutment block 482 and push the abutment block 482 along the direction of the connecting column 483, thereby making the sleeve 481 with the abutment block 482 installed reset.
[0020] In one embodiment of this application, such as Figure 3 As shown, a positioning component 5 is provided on the first connecting flange 1. The positioning component 5 includes a connecting rod 51 and a limiting plate 52. The connecting rod 51 is provided on the first connecting flange 1, and the limiting plate 52 is connected to the other end of the connecting rod 51. An installation hole 53 is provided on the second connecting flange 2, and a sliding groove 54 is provided in the installation hole 53.
[0021] Specifically, when it is necessary to align the first connecting flange 1 and the second connecting flange 2 and fasten them with bolts, the relevant personnel first align and insert the limiting plate 52, which is installed on the first connecting flange 1 via the connecting rod 51, with the mounting hole 53 on the second connecting flange 2. Then, the first connecting flange 1 is rotated, at which point the limiting plate 52 will move along the slide groove 54. When the limiting plate 52 contacts the bottom wall of the slide groove 54, the connecting holes on the first connecting flange 1 and the second connecting flange 2 will be aligned, and finally, the relevant personnel can fasten the connection with bolts.
[0022] In summary, by adding a fixing structure to the outside of the flange adapter and reinforcing the pipe inserted into the flange adapter, it is not easy to fall off during use and cannot be disassembled during flange connection. The sealing ring ensures the sealing of the pipe and adapter connection. At the same time, the positioning component allows the flange adapter to be quickly positioned during docking, thereby improving installation efficiency.
