[0002] A flange cover, also known as a blind flange or pipe plug, is a flange without a hole in the middle, used to block the pipe opening, and its function is the same as that of a head and a pipe cap. The flange cover seal is a detachable sealing device. The chemical industry, also known as the chemical processing industry, generally refers to the process industry in which chemical methods play a major role in the production process. In the chemical industry, the transportation of liquid chemicals requires the use of chemical pipelines for transportation, and a flange cover is needed for sealing when connecting chemical pipelines.

[0003] In the prior art, the patent application with the publication number of CN219775154U proposed adopts a quick-disassembly mechanism. When it is necessary to disassemble the flange cover, by rotating the adjusting part rotating disc, the limiting column moves to one end closer to the axis of the rotating disc in the limiting groove. At this time, the sliding rod will completely move into the sliding groove, and the thread at one end of the sliding rod will disengage from the bolt, and a large gap will be left at the contact position between one end of the bolt and the thread groove. At this time, gently shaking the flange cover can remove the flange cover, making the disassembly of the flange cover more convenient and fast.

[0004] However, when installing it, the flange cover is pressed into the flange, so that the internal clamping parts of the flange cover are clamped with the internal clamping grooves of the flange. At this time, the installation holes will be aligned with the notch openings, and when multiple bolts are respectively rotated and inserted into the multiple installation holes, the flange cover and the flange can be connected through the threads and the thread grooves, thus making it inconvenient to quickly install the flange cover.

[0005] Therefore, it is necessary to provide a quick-opening mechanism for a flange cover and a flange device to solve the above technical problems. Content of the Utility Model

[0006] The utility model provides a quick-opening mechanism for a flange cover and a flange device, which solves the problem that it is inconvenient to quickly install the flange cover at present.

After the flange cover 3 is installed, by releasing the pressing handle 6, a plurality of fixing springs 10 push a plurality of fixing pins 9 into the interiors of a plurality of fixing holes 7 respectively, thereby limiting the flange cover 3, so as to prevent the flange cover 3 from rotating to one side due to vibration and becoming loose, and increasing the fixing effect.

[0044] Second Embodiment

[0045] Please refer to Figure 5 、 Figure 6 and Figure 7 Based on a quick-opening mechanism for a flange cover and a flange device provided in the first embodiment of the present application, the second embodiment of the present application proposes another quick-opening mechanism for a flange cover and a flange device. The second embodiment is merely a preferred manner of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0046] Specifically, the difference of a quick-opening mechanism for a flange cover and a flange device provided in the second embodiment of the present application is that, for a quick-opening mechanism for a flange cover and a flange device, a plurality of sliding grooves 12 are formed inside the flange cover 3, and a plurality of sliding blocks 13 are slidably connected inside the plurality of sliding grooves 12.

[0047] A plurality of limiting grooves 14 are formed inside the flange cover 3, and one ends of the plurality of limiting grooves 14 are respectively connected to one ends of one sides of the plurality of sliding grooves 12.

[0048] One ends of the plurality of sliding blocks 13 are fixedly connected to the surface of the moving ring 5, and are used for limiting the moving ring 5 after the plurality of sliding blocks 13 move from the inside of the sliding grooves 12 to one side and enter the inside of the limiting grooves 14.

[0052] The working principle of a quick-opening mechanism for a flange cover and a flange device provided by the present utility model is as follows:

[0053] During use, when the push handle 6 is pressed down to move downward, it drives the moving ring 5 to move downward. As a result, multiple sliding blocks 13 are respectively driven to move downward inside multiple sliding grooves 12 to appropriate positions. Then, the push handle 6 is rotated to one side, driving the moving ring 5 to rotate to one side, thereby driving multiple sliding blocks 13 into multiple limiting grooves 14. At the same time, the rotating ring 16 rotates to one side inside the rotating groove 15. When the sliding groove 13 moves to an appropriate position to one side, the moving ring 6 is limited.

[0054] Compared with the related art, a flange cover quick-opening mechanism and a flange device provided by the present utility model have the following beneficial effects:
