Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 , the utility model provides a technical solution:

[0020] A flange structure, comprising a flange 1 and a flange 2, wherein the flange 1 and the flange 2 are matched in size, and the flange 1 and the flange 2 are both provided with evenly distributed and symmetrical screw holes 3, bolts 4 are slidably provided on the screw holes 3, nuts 5 are threadedly connected on the bolts 4, gears 6 are fixedly installed on the heads of the bolts 4, a gear ring 7 is rotatably provided on the flange 1, multiple groups of the gears 6 are meshed and transmission-connected with the gear ring 7, a movable rod 8 is provided on the gear ring 7, and the A limiting member 9 for limiting the nut 5 is provided on the flange 2, and the limiting member 9 includes sliding grooves 91 evenly distributed on the flange 2, a limiting plate 92 slidably arranged on the sliding groove 91, and a spring 93 fixedly installed in the sliding groove 91, and the spring 93 is pressed between the flange 2 and the limiting plate 92, and the limiting plate 92 is set to an arc shape that is compatible with the nut 5. The size of the limiting plate 92 is compatible with the size of the nut 5, and the limiting plate 92 is respectively fitted with the side edges of the nut 5.

[0021] Flange 1 and flange 2 are provided with evenly distributed screw holes 3, which are symmetrical to ensure that the two flanges can be accurately aligned. Bolts 4 are slidably arranged on the screw holes 3 and connected with nuts 5 through threads, so that bolts 4 can easily pass through the screw holes 3 of flange 1 and flange 2, and then the two flanges are tightened by rotating nuts 5. Each bolt 4 head is equipped with a gear 6, which is meshed with the toothed ring 7 on flange 1. When the toothed ring 7 is rotated, all bolts 4 will rotate at the same time through meshing transmission, so that all nuts 5 can be loosened at one time, simplifying the disassembly process between flanges, which is particularly suitable for scenes that require frequent disassembly. The movable rod 8 is used to operate the toothed ring 7, providing a convenient rotation torque, and the elastic restoring force of the spring 93 in the slide groove 91 on the limit plate 92 can make the limit plate 92 tightly press the nut 5, thereby improving the stability of the loosening of the nut 5. The flange structure can realize simple disassembly between flanges, which is suitable for scenes that require frequent disassembly, such as equipment maintenance, pipeline replacement, etc., and improves the convenience of operation and work efficiency.

[0022] The edge of the limiting plate 92 close to the nut 5 is configured as an arc edge;

[0023] The edge of the limiting plate 92 close to the nut 5 is designed as an arc edge, which can reduce the friction between the limiting plate 92 and the nut 5, so that the nut 5 can be tightened or loosened more smoothly, reduce wear, and improve work efficiency.

[0024] The gear ring 7 is provided with evenly distributed sockets 10, and an insert block 11 is fixedly installed at the end of the movable rod 8. The insert block 11 is slidably arranged on the socket 10, and a damper is arranged between the insert block 11 and the socket 10;

[0025] The insert block 11 at the end of the movable rod 8 can be inserted into different sockets 10 to rotate the gear ring 7. Damping is provided between the insert block 11 and the socket 10 to improve the stability of the movable rod 8. After the movable rod 8 is removed, the gear ring 7 cannot be rotated.

[0026] A sealing rubber plate is provided between flange 1 and flange 2;

[0027] The sealing rubber plate arranged between flange 1 and flange 2 plays a role of sealing and leak prevention. When the two flanges are tightly connected, the sealing rubber plate can effectively prevent liquid or gas from leaking from the flange connection, thereby enhancing the reliability and safety of the flange connection.

[0028] Working principle:

[0029] Evenly distributed screw holes 3 are provided on flange 1 and flange 2. These screw holes 3 are symmetrical to ensure that the two flanges can be accurately aligned. Bolts 4 are slidably set on the screw holes 3 and connected to nuts 5 through threads, so that bolts 4 can easily pass through the screw holes 3 of flange 1 and flange 2, and then the two flanges are tightened by rotating nuts 5. Each bolt 4 head is equipped with a gear 6, which meshes with the toothed ring 7 on flange 1. When the toothed ring 7 is rotated, all bolts 4 will rotate at the same time through meshing transmission, so that all nuts 5 can be loosened at one time, simplifying the disassembly process between flanges, which is particularly suitable for scenes that require frequent disassembly. The movable rod 8 is used to operate the toothed ring 7, providing a convenient rotation torque. Through the elastic restoring force of the spring 93 in the slide groove 91 on the limit plate 92, the limit plate 92 can tightly press the nut 5, thereby improving the stability of the loosening of the nut 5;

[0030] The edge of the limiting plate 92 close to the nut 5 is designed as an arc edge, which can reduce the friction between the limiting plate 92 and the nut 5, so that the nut 5 can be tightened or loosened more smoothly, reduce wear, and improve work efficiency;

[0031] The insert block 11 at the end of the movable rod 8 can be inserted into different sockets 10 to rotate the gear ring 7. A damping is provided between the insert block 11 and the socket 10 to improve the stability of the movable rod 8. After the movable rod 8 is removed, the gear ring 7 cannot be rotated.

[0032] The sealing rubber sheet arranged between flange 1 and flange 2 plays a role of sealing and leak prevention. When the two flanges are tightly connected, the sealing rubber sheet can effectively prevent liquid or gas from leaking from the flange connection, thereby enhancing the reliability and safety of the flange connection.

[0033] This flange structure can realize easy disassembly between flanges and is suitable for scenarios that require frequent disassembly, such as equipment maintenance, pipeline replacement, etc., which improves the convenience of operation and work efficiency.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
