[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, a rubber hose split flange type connector includes a first split flange 5 and a second split flange 8, mainly used for connecting pipeline systems that transport normal temperature and low pressure liquids. When assembling the connector, the first split flange 5 and the second split flange 8 are first installed on both ends of the rubber hose body 1, respectively. The first split flange 5 and the second split flange 8 are both semi-circular, and together they can form a complete circular flange. Connecting blocks 11 are welded to the two end faces of the second split flange 8, and mounting holes are opened on the connecting blocks 11 to facilitate subsequent connection and fixation with other components. Grooves for the connecting blocks 11 are opened on the two end faces of the first split flange 5, and mounting through holes are opened on one side wall of the first split flange 5 through the grooves. After the connecting blocks 11 are inserted into the grooves, they can be further fixed by using connecting bolts 7 through the mounting through holes. If necessary, sealing rings can be set at the connection between the first split flange 5 and the second split flange 8 and the rubber hose body 1 to further enhance the sealing effect.

[0022] Next, mounting plates 9 are welded to the side walls of the second split flange 8. Threaded holes are made on the mounting plates 9, and the connecting screw 10 is screwed into the threaded holes for fixation. A second rotating plate 6 is welded to the top of the connecting screw 10 to facilitate the operator's rotation of the connecting screw 10. A support plate 4 is set on the upper part of the connecting screw 10. Threaded holes matching the connecting screw 10 are made on both sides of the support plate 4, and a threaded hole matching the extrusion screw 2 is made in the middle. The extrusion screw 2 is passed through the threaded hole in the middle of the support plate 4. A first rotating plate 3 is welded to the top of the extrusion screw 2. Multiple rotating rods are evenly welded to the outer ring of the first rotating plate 3 to facilitate the operator's rotation of the extrusion screw 2.

[0023] An extrusion block 12 is welded to the top of the first split flange 5. The extrusion block 12 is cylindrical, and its top has a groove for the bottom end of the extrusion screw 2 to be inserted. When it is necessary to connect the rubber hose, the first split flange 5 and the second split flange 8 can be placed at one end of the rubber hose body 1. By rotating the second rotating plate 6, the connecting screw 10 is rotated out from the threaded hole on the support plate 4, and the lower end of the connecting screw 10 is rotated into the threaded hole on the mounting plate 9. The support plate 4 can be raised or lowered to a suitable position. Then, the first rotating plate 3 is rotated to move the extrusion screw 2 downward. The bottom end enters the groove at the top of the extrusion block 12, and the first split flange 5 and the second split flange 8 are tightly fitted into the rubber hose body 1 through extrusion. Then, the first split flange 5 and the second split flange 8 can be connected together by connecting bolts 7, and matching nuts are set on the connecting bolts 7 to fix the first split flange 5 and the second split flange 8, so as to achieve a reliable connection and effectively prevent liquid leakage. After installation, the extrusion screw 2, the first rotating plate 3, the support plate 4, the second rotating plate 6 and the connecting screw 10 can be removed from the first split flange 5 or the second split flange 8.

[0024] Example 2: Please refer to Figure 1 , Figure 2 and Figure 3 This rubber hose split flange joint is used in pipeline systems that transport media with certain corrosive properties. During the assembly process, the first split flange 5 and the second split flange 8 are installed with the rubber hose body 1, as well as the connecting block 11, mounting plate 9, support plate 4, extrusion screw 2, first rotating plate 3, second rotating plate 6 and other components are installed first. The installation method of each component is the same as in Embodiment 1.

[0025] Because the medium being transported is corrosive, the rubber hose body 1 is made of a rubber material with good corrosion resistance, such as nitrile rubber. The metal parts such as the first split flange 5, the second split flange 8, the connecting block 11, the mounting plate 9, the support plate 4, the connecting screw 10, the extrusion screw 2, and the connecting bolt 7 are all made of stainless steel to improve the corrosion resistance of the joint and extend its service life. The appropriate materials can be selected to make the corresponding parts according to the different media being transported.

[0026] When connecting the rubber hose, follow the steps in Example 1. Use the second rotating plate 6 and the first rotating plate 3 to adjust the position of the support plate 4 and the compression screw 2 so that the first split flange 5 and the second split flange 8 are tightly fitted onto the rubber hose body 1. Then, use the connecting bolts 7 and nuts to initially fix the connection between the first split flange 5 and the second split flange 8. Finally, the compression screw 2, the first rotating plate 3, the support plate 4, the second rotating plate 6, and the connecting screw 10 can be removed from the first split flange 5 or the second split flange 8. This design not only ensures the reliability of the joint in corrosive media environments, but also facilitates installation and disassembly, making it convenient for maintenance and repair of the pipeline system.

[0027] Implementation Results: This rubber hose split flange joint adopts a split flange design. The first split flange 5 and the second split flange 8 can form a complete flange and are respectively installed at both ends of the rubber hose body 1. This structure allows the joint to be installed and disassembled without requiring a large operating space, making it particularly suitable for narrow environments and greatly facilitating the assembly and maintenance of the pipeline system. Simultaneously, a mounting plate 9 is welded to the side wall of the second split flange 8 and connected to the support plate 4 via a connecting screw 10. A compression screw 2 is installed on the support plate 4, and a compression block 12 is welded to the top of the first split flange 5. By rotating the first rotating plate 3, the compression screw 2 is moved, achieving a convenient and tight compression connection between the first split flange 5 and the second split flange 8 and the rubber hose body 1. The operation is simple and efficient, providing a tight and stable connection.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
