DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0025] like Figure 1-Figure 5 As shown, an embodiment of the present application provides a pipeline flange that is easy to install, including:

[0026] A first connecting cylinder 1 and a second connecting cylinder 2 are coaxially arranged, and opposite sides of the first connecting cylinder 1 and the second connecting cylinder 2 are respectively connected with a first connecting disk 3 and a second connecting disk 4, and the second connecting disk 4 is provided with a plurality of annularly distributed plug holes 5, the first connecting cylinder 1 and the first connecting disk 3 form a first flange body, and the second connecting cylinder 2 and the second connecting disk 4 form a second flange body, and pipelines are respectively connected to the free ends of the first connecting cylinder 1 and the second connecting cylinder 2;

[0027] An adjusting ring 6 is threadedly sleeved on the first connecting tube 1. A movable ring 7 is coaxially rotated on one side of the adjusting ring 6. An annular groove is provided on one side of the movable ring 7. An annular slider that slides with the annular groove is constructed on one side of the adjusting ring 6. The longitudinal sections of the annular groove and the annular slider are both constructed in a T shape. The adjusting ring 6 is twisted to rotate and move, thereby driving the movable ring 7 to move synchronously. At the same time, the threaded cooperation between the adjusting ring 6 and the first connecting tube 1 is self-locking, and the driving adjusting ring 6 can be self-locking after moving. A plurality of support rods 8 are hingedly connected to the outer peripheral array of the movable ring 7. A plurality of free ends of the support rods 8 are provided with plug rods 9. A plurality of plug rods 9 are respectively inserted and matched with a plurality of sockets 5. When connecting two adjacent flange bodies, the first connecting disk 3 is brought close to the second connecting disk 4, and the two are coaxially aligned. A plurality of support rods 8 are arranged around the hinge point. Rotate, and make several insertion rods 9 respectively inserted in several insertion holes 5, twist the adjusting ring 6 to rotate and move, thereby driving the movable ring 7 to move, so that several support rods 8 pull the second connecting plate 4 close to and resist the first connecting plate 3, and use the extrusion resistance force to fix the first connecting plate 3 and the second connecting plate 4, thereby completing the flange connection. The overall structure of the device uses the insertion and coordination of the insertion rod 9 and the insertion hole 5 to connect the support rod 8 with the second connecting plate 4. Multiple support rods 8 are distributed in a ring shape, so that the second connecting plate 4 has multiple pulling points in the circumferential direction. It only needs to twist the adjusting ring 6 to rotate and move, so that multiple support rods 8 synchronously pull the second connecting plate 4, thereby fixing the first connecting plate 3 and the second connecting plate 4. Compared with the existing locking by multiple sets of bolts and nuts, it is more convenient and quick, thereby improving practicality.

[0028] like Figure 1 , Figure 2 and Figure 5As shown, in some embodiments, the socket 5 is opened on the side of the second connecting disk 4 away from the first connecting disk 3, the support rod 8 is constructed in an L shape, and the insertion rod 9 is located on the inner side of the bending portion of the support rod 8. By opening the socket 5 on the side of the second connecting disk 4 away from the first connecting disk 3, and the support rod 8 is constructed in an L shape, when the insertion rod 9 is inserted into the socket 5, the connectivity between the support rod 8 and the second connecting disk 4 is further improved. When the adjustment ring 6 rotates and moves, the connectivity between the support rod 8 as a whole and the second connecting disk 4 is better, and the fixing effect of the first connecting disk 3 and the second connecting disk 4 is better.

[0029] like Figure 2 and Figure 3 As shown, in some embodiments, the first connection disk 3 and the second connection disk 4 are both provided with ring plates 10 on opposite sides, wherein one of the ring plates 10 is provided with a plurality of grooves 11 distributed in an annular manner, and the other ring plate 10 is provided with a plurality of blocks 12 in an array structure, and the plurality of blocks 12 are respectively engaged with the plurality of grooves 11. The particles (especially the liquid) in the pipeline have stress during transportation, and the stress is transmitted to the flange body. Preferably, the block 12 is constructed as an L-shaped block, and the groove 11 is constructed as an L-shaped groove. When the first connection disk 3 is close to the second connection disk 4, the two ring plates 10 are mutually engaged. Get closer, movably insert several blocks 12 on the other ring plate 10 into several grooves 11 on one of the ring plates 10, and then rotate the first connecting disk 3 and the second connecting disk 4 in opposite directions respectively, so that the two ring plates 10 are synchronously rotated in opposite directions by a certain angle, and the two are connected by the structure of the blocks 12 and the grooves 11. Through the connection of the blocks 12 and the grooves 11, the two ring plates 10 are used to pull and lock the first connecting disk 3 and the second connecting disk 4, share the stress, avoid all the stress from being transmitted to the support rod 8, and further improve the stability of the connection between the two flange bodies.

[0030] like Figure 5 As shown, in some embodiments, annular grooves 13 are provided on opposite sides of the first connecting disk 3 and the second connecting disk 4, and the two ring plates 10 are rotatably arranged in the two annular grooves 13 respectively. Preferably, an annular groove is provided on the inner wall of the annular groove 13, and an annular slider slidably matched with the annular groove is constructed on the ring plate 10. The longitudinal sections of the annular groove and the annular slider are both constructed in a T shape. When the two ring plates 10 are close to each other and the block 12 is plugged into the groove 11, there is no need to rotate the first connecting disk 3 and the second connecting disk 4 (when the pipeline has a certain length, after the first connecting tube 1 and the second connecting tube 2 are respectively connected to the pipeline, a certain stress is required to rotate the first connecting disk 3 and the second connecting disk 4), and only the two ring plates 10 need to be rotated, which further improves the convenience of installation.

[0031] like Figure 1 and Figure 3As shown, in some embodiments, a plurality of limiting grooves 14 are arranged in an array on the outer circumference sides of the two ring plates 10, and the support rods 8 are engaged with the limiting grooves 14. Preferably, the number of limiting grooves 14 on the same ring plate 10 is the same as the number of support rods 8. When the two ring plates 10 are fitted together and the two ring plates 10 are twisted so that the clamping blocks 12 and the clamping grooves 11 are smoothly engaged, the plurality of limiting grooves 14 on the two ring plates 10 are connected one by one. At this time, the support rods 8 are rotated around the hinge points and engaged in the two corresponding limiting grooves 14, so that the two ring plates 10 can be limited and the two ring plates 10 can be restricted from rotating, so that the clamping block 12 and the clamping groove 11 are more firmly engaged, thereby further improving the stability of the flange connection.

[0032] like Figure 5 As shown, in some embodiments, annular grooves 15 are provided on opposite sides of the first connecting plate 3 and the second connecting plate 4, and sealing rings 16 are embedded in the two annular grooves 15. When the first connecting plate 3 and the second connecting plate 4 are overlapped, the sealing rings 16 will be squeezed, thereby making the connection between the first connecting plate 3 and the second connecting plate 4 more sealed, thereby improving the sealing of the flange connection.

[0033] like Figure 2 and Figure 4 As shown, in some embodiments, a positioning ring 17 is fixedly provided on the first connecting tube 1, and a spring washer 18 sleeved on the first connecting tube 1 is installed between the positioning ring 17 and the adjusting ring 6. When the adjusting ring 6 is twisted and rotated, the adjusting ring 6 will squeeze the spring washer 18, and the spring washer 18 applies a counter-resistance force to the adjusting ring 6. The counter-resistance force prevents the flange from being subjected to the stress of vibration that causes the adjusting ring 6 to rotate loose, thereby further ensuring the stability of the flange connection.

[0034] like Figure 1 and Figure 2 As shown, in some embodiments, a plurality of slots 19 distributed in a ring shape are provided in an array on the outer peripheral side of the adjustment ring 6. Through the slots 19, when the adjustment ring 6 is rotated, tools such as pins can be inserted into the slots 19 to facilitate better rotation of the adjustment ring 6, thereby improving the convenience of installation.

[0035] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
