[0027] like Figures 1 to 3As shown, this utility model embodiment provides a split movable flange, including two semi-circular flange bodies 1, which are symmetrically arranged. The two semi-circular flange bodies 1 are joined together to form a flange ring. The flange ring has a plurality of flange holes 11, which are arranged circumferentially. The diameter of the flange holes 11 matches that of standard flange bolts. Each semi-circular flange body 1 has a first connecting end 12 and a second connecting end 13 at both ends. A connecting piece 2 is disposed between the two semi-circular flange bodies 1 for connecting the two semi-circular flange bodies 1. There are two sets of connecting pieces 2. The first connecting end 12 of one semi-circular flange body 1 is connected to the second connecting end 13 of the other semi-circular flange body 1 through one of the connecting pieces 2, and the first connecting end 12 of the other semi-circular flange body 1 is connected to the second connecting end 13 of one semi-circular flange body 1 through the other connecting piece 2. The first connecting end 12 and the second connecting end 13 on the same semi-circular flange body 1 are offset in position, which means offset along the axial extension direction of the flange ring.

[0028] This utility model embodiment provides a split movable flange, including two semi-circular flange bodies 1. The two semi-circular flange bodies 1 are joined together to form a flange ring, and the flange ring has a plurality of flange holes 11. A connecting piece 2 is used to connect the first connecting end 12 of one semi-circular flange body 1 and the second connecting end 13 of the other semi-circular flange body 1. During installation, the two semi-circular flange bodies 1 and the connecting piece 2 are locked with bolts to complete the installation. The structure is sturdy, easy to install and disassemble, suitable for various scenarios, and easy to disassemble and maintain.

[0029] In some embodiments, such as Figures 1 to 3As shown, the first connecting end 12 includes a first locking block 121 and a first fitting groove 122, and the second connecting end 13 includes a second locking block 131 and a second fitting groove 132. Specifically, the first connecting end 12 has a first locking groove 123, and the second fitting groove 132 has a second locking groove 133. When the two semi-circular flange bodies 1 are joined together, one end of the connecting piece 2 is engaged in the first locking groove 123, and the other end of the connecting piece 2 is engaged in the second locking groove 133. The connecting piece 2 has a through hole 21, and both the first locking block 121 and the second locking block 131 have flange holes 11. When the two semi-circular flange bodies 1 are joined together, the flange holes 11 on the first locking block 121 and the second locking block 131 are aligned with and communicate with the through holes 21. Specifically, in this embodiment of the present invention, when the two semi-circular flange bodies 1 are joined together, the first locking block 121 of one semi-circular flange body 1 is positioned and fitted with the second fitting groove 132 of the other semi-circular flange body 1, and the second locking block 131 of the other semi-circular flange body 11 fits into the first fitting groove 122 of one semi-circular flange body 1. At this time, the flange holes 11 on the first locking block 121 and the second locking block 131 are aligned and communicate with the through hole 21, and the connecting piece 2 and the two semi-circular flange bodies 1 can be locked and fixed by standard flange bolts. At the same time, the two ends of the connecting piece 2 are respectively inserted into the first locking groove 123 and the second locking groove 133, which can be aligned and positioned.

[0030] like Figures 1 to 3 As shown, to further facilitate positioning, the connecting piece 2 is pre-fixed within the first slot 123. The first locking block 121 has a first screw hole 124, and the connecting piece 2 has a second screw hole 22. The connecting piece 2 can be fixed to the first locking block 121 using screws 3. Both the first screw hole 124 and the second screw hole 22 are provided in two sets. In actual installation, simply aligning the connecting piece 2 with the second slot 133 and inserting it is sufficient to complete the positioning and installation. The second locking block 131 also has a third screw hole 134. When the connecting piece 2 is inserted into the second slot 133, the screw 3 can further lock into the third screw hole 134, further securing the connecting piece 2 and making the entire connection structure more robust.
