For some well-known technologies, those skilled in the art may also adopt other alternative methods to implement; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0026] like Figure 1 - Figure 5 As shown, an embodiment of the utility model provides a galvanized flange, including a first flange 1, a first connecting pipe 2 is fixedly connected to one side of the first flange 1, a second flange 3 is arranged on one side of the first connecting pipe 2, a second connecting pipe 4 is fixedly connected to one side of the second flange 3, a stud 5 is sleeved between the first flange 1 and the second flange 3, nuts 6 are sleeved at both ends of the stud 5, a pressure ring 7 is installed on one side of the nut 6, a spring leaf ring 8 is arranged on one side of the pressure ring 7, a fastening hoop 9 is arranged on one side of the spring leaf ring 8, and the fastening hoop 9 is sleeved at the joint between the first flange 1 and the second flange 3.

[0027] By docking the first flange 1 with one side of the second flange 3, sleeved the sealing sleeve 14 at the docking point, and then tightened by the fastening hoop 9, the first flange 1 and the second flange 3 are connected more tightly, thereby improving the sealing of the connection, and the stud 5 is sleeved between the first flange 1 and the second flange 3, twisting the nut 6, the nut 6 and the stud 5 are threadedly connected, so that the nut 6 presses the pressure ring 7 close to the spring leaf ring 8, so that the pressure ring 7 squeezes the spring leaf ring 8, and the spring leaf ring 8 generates a reverse elastic force, which pushes the nut 6 in the reverse direction, so that the stud 5 and the nut 6 are connected more tightly, thereby further improving the tightness of the connection between the first flange 1 and the second flange 3, and the number of bolts can be reduced, the difficulty of loading and unloading is reduced, and loading and unloading is more convenient.

[0028] like Figure 1 - Figure 3 As shown, a large top cover 10 is slidingly sleeved on one side of the first flange 1, and a small top cover 11 is slidingly sleeved on one side of the second flange 3. The large top cover 10 and the small top cover 11 are threadedly connected, and a top rod 12 is fixedly connected inside the large top cover 10 and the small top cover 11. A connecting hole 13 is opened on the first flange 1 and the second flange 3, and the stud 5 is slidingly sleeved in the connecting hole 13.

[0029] The connection hole 13 is provided to facilitate the insertion of the stud 5. After the stud 5 docks and fixes the first flange 1 and the second flange 3, the large top cover 10 is inserted from one side of the first flange 1, and the small top cover 11 is inserted from one side of the second flange 3, so as to facilitate the docking between the large top cover 10 and the small top cover 11. The large top cover 10 and the small top cover 11 are fixed to the outside of the first flange 1 and the second flange 3 through the threaded connection between the large top cover 10 and the small top cover 11. At the same time, one end of the push rod 12 fixedly connected to the large top cover 10 and the small top cover 11 is pressed against one side of the first flange 1 and the second flange 3, so that the connection between the first flange 1 and the second flange 3 is more stable and can also be protected.

[0030] Example 2 - Figure 5 The pressure ring 7 and the spring leaf ring 8 are both sleeved on the stud 5. The outer ring surface of the joint between the first flange 1 and the second flange 3 is sleeved with a sealing sleeve 14. The fastening hoop 9 is sleeved on the outer ring surface of the sealing sleeve 14. One end of the fastening hoop 9 is fixed in the fixed plate 15, and the other end of the fastening hoop 9 is movably sleeved on the connecting rod 16. The upper side of the connecting rod 16 is fixedly connected with the locking bolt 17. The locking bolt 17 is sleeved in the fixed plate 15 and is threadedly connected to the fixed plate 15. A limiting ring 18 is sleeved on the connecting rod 16 and is rotatably connected to the limiting ring 18.

[0031] The two ends of the stud 5 are sleeved in the connecting hole 13, and the nut 6 is twisted so that the nut 6 presses the pressure ring 7 to move in the direction close to the spring leaf ring 8, so that the pressure ring 7 squeezes the spring leaf ring 8, and the spring leaf ring 8 is drum-shaped, so that the spring leaf ring 8 is deformed by force, and a reverse elastic force is generated, which pushes the nut 6 in the reverse direction, thereby making the stud 5 and the nut 6 fit more tightly, and further preventing the nut 6 from loosening, and sleeve the sealing sleeve 14 at the joint between the first flange 1 and the second flange 3, and then twist the locking bolt 17. Due to the threaded connection between the locking bolt 17 and the fixing plate 15, the locking bolt 17 will push one end of the fastening hoop 9 to move through the cooperation of the connecting rod 16 and the limiting ring 18. Since the other end of the fastening hoop 9 is fixedly sleeved in the fixing plate 15, the inner diameter of the fastening hoop 9 can be gradually reduced, so that the fastening hoop 9 can tighten the sealing sleeve 14, thereby improving the sealing performance and increasing the tightness of the connection between the first flange 1 and the second flange 3.

[0032] The technical solution provided by the utility model, in actual use, by docking the first flange 1 with one side of the second flange 3, the sealing sleeve 14 is sleeved at the docking position, and by twisting the locking bolt 17, due to the threaded connection between the locking bolt 17 and the fixing plate 15, the locking bolt 17 will push one end of the fastening hoop 9 to move through the cooperation of the connecting rod 16 and the limiting ring 18, and because the other end of the fastening hoop 9 is fixedly sleeved in the fixing plate 15, the inner diameter of the fastening hoop 9 can be gradually reduced, so that the fastening hoop 9 can tighten the sealing sleeve 14, thereby improving the sealing performance and increasing the first flange 1 and The tightness of the second flange 3 connection, and then the two ends of the stud 5 are sleeved in the connecting hole 13, and the nut 6 is twisted, so that the nut 6 will press the pressure ring 7 to move towards the direction close to the spring ring 8, so that the pressure ring 7 squeezes the spring ring 8, and the spring ring 8 is drum-shaped, so that the spring ring 8 is deformed by force, and a reverse elastic force is generated, which pushes the nut 6 in the reverse direction, thereby making the stud 5 and the nut 6 fit more tightly, and further preventing the nut 6 from loosening, and finally the large top cover 10 is inserted from one side of the first flange 1, and the small top cover 11 is inserted from one side of the second flange 3, so that the large top cover 10 is convenient for The large top cover 10 and the small top cover 11 are connected to each other by a threaded connection, so that the large top cover 10 and the small top cover 11 are fixed to the outside of the first flange 1 and the second flange 3. At the same time, one end of the push rod 12 fixedly connected to the large top cover 10 and the small top cover 11 supports one side of the first flange 1 and the second flange 3, thereby making the connection between the first flange 1 and the second flange 3 more stable and protecting them at the same time. When disassembly is required, it is only necessary to unscrew the large top cover 10 and the small top cover 11, twist the locking bolts 17 in the opposite direction, and remove the four studs 5, thereby reducing the number of bolts, reducing the difficulty of loading and unloading, and making loading and unloading more convenient.
