[0002] The steel press-fit multi-directional adjusting joint is a precision pipe fitting that integrates mechanical connection, multi-dimensional adjustment and sealing functions.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1 to 5 As shown, the steel press-opening multi-directional adjusting joint with self-locking mechanism of this utility model embodiment includes a bellows 1; flange slots 11 are fixedly connected to both ends of the bellows 1; a self-locking assembly is provided between a pair of flange slots 11; a flange quick-installation assembly is provided on the side wall of the flange slot 11; a release assembly is provided on the flange slot 11 through the self-locking assembly; a sealing assembly is provided on the inner side wall of the flange slot 11; during operation, when it is necessary to adjust the angle of the device, the release assembly is activated to release the self-locking assembly, the flange slot 11 is rotated to position both ends of the bellows 1 in a suitable position, the release assembly is released, the self-locking assembly fixes the angle of the bellows 1, and then the device to be installed is installed... The flange for the pipe is inserted into the flange slot 11 and fixed by the flange quick-connect assembly. The device is then installed in the piping system. The sealing assembly seals the flange slot 11 and the flange. Through the above structure, the self-locking assembly fixes the bellows 1 after the angle is adjusted, forming a steel pressure-opening multi-directional adjusting joint structure with a self-locking mechanism. This achieves the function of self-locking after the angle of the bellows 1 is adjusted, solving the problem that the angle of the bellows 1 changes due to external force after the angle adjustment, improving the accuracy of the bellows 1 installation, and reducing the situation where the angle of the bellows 1 changes due to external force.

[0020] like Figures 1 to 4As shown, the self-locking assembly includes a support rod 12, a rotating plate 13, a friction plate 14, a rotating shaft 15, a spring 16, and a rotating block 17. The rotating block 17 is rotatably connected to the adjacent side walls of the flange slots 11. Rotating blocks 17 are provided on both side walls of the pair of flange slots 11 and are arranged symmetrically. The support rod 12 is hinged to the side wall of the rotating block 17. The rotating plate 13 is fixedly connected to the end of the support rod 12 away from the flange slot 11. A pair of rotating plates 13 are rotatably connected to the outer side wall of the rotating shaft 15. The spring 16 is sleeved on the outer side wall of the rotating shaft 15 away from the rotating plate 13. A pair of springs 16 are provided on the outer side wall of the rotating shaft 15 and are arranged symmetrically. The friction plate 14 is fixedly connected to the adjacent side walls of the rotating plates 13. Friction plates 14 are provided on both side walls of the pair of adjacent rotating plates 13. A reinforcing assembly is provided on the adjacent side walls of the support rod 12. During operation, when the release assembly is activated, the pressure between the rotating plate 13 and the friction plate 14 decreases, and the rotation direction is adjusted according to the angle of the bellows 1. When the bellows 1 bends, the flange slot 11 drives the support rod 12 to swing when the bellows 1 is in the appropriate position. The pair of rotating plates 13 rotate relative to each other. After the bellows 1 angle is adjusted, the release assembly resets. The pair of rotating plates 13 are subjected to the pressure of the spring 16, which increases the friction between the pair of friction plates 14, restricting the rotation of the rotating plates 13 and the support rod 12, thereby fixing the angle of the bellows 1. There is friction between the rotating block 17 and the flange slot 11. After the rotating block 17 rotates to the appropriate angle, it remains stationary. Through the above structure, the setting of increased friction when the rotating plates 13 and friction plates 14 are subjected to pressure forms a self-locking structure for the bellows 1, realizing the self-locking function after the bellows 1 angle is adjusted. This solves the problem of the bellows 1 angle changing due to external force after the bellows 1 angle is adjusted, improves the stability of the bellows 1 angle after adjustment, and reduces the situation of inaccurate installation caused by changes in the bellows 1 angle after adjustment.

[0021] like Figure 3As shown, the release assembly includes a squeezing plate 2, a toggle bracket 21, and a pressing block 22. The squeezing plate 2 is slidably connected to the outer wall of the rotating shaft 15 away from the friction plate 14. A pair of squeezing plates 2 are provided on the outer wall of the rotating shaft 15, and they are arranged symmetrically. The toggle bracket 21 is fixedly connected to the outer wall of the squeezing plate 2. The toggle bracket 21 is provided on the outer wall of both pairs of squeezing plates 2. The pair of toggle brackets 21 are slidably connected. The pressing block 22 is fixedly connected to the ends of the toggle brackets 21 that are far apart from each other. The outer wall of the pressing block 22 is provided with an anti-slip component. During operation, when the bellows 1 is adjusted at an angle, the pair of pressing blocks 22 are squeezed towards the middle, and the pressing block 22 drives the toggle bracket 21. The pressure plate 2 is displaced, causing the pair of pressure plates 2 to move away from each other. The pressure plate 2 compresses the spring 16, reducing the pressure between the friction plates 14 and lowering the friction between the friction plates 14, which facilitates the rotation of the support rod 12 and the rotating plate 13. After rotation, the pressing block 22 is released, and the spring 16 drives the pressure plate 2 and the actuating frame 21 to reset. Through the above structure, the setting of the pressing block 22 driving the pressure plate 2 to compress the spring 16 forms a self-locking release structure, which realizes the function of compressing the spring 16 to reduce the friction between the friction plates 14, improves the convenience of disabling the self-locking structure, and increases the convenience of adjusting the angle of the bellows 1.

[0022] like Figure 1 and Figure 2 As shown, the flange quick-connect assembly includes a flange fixing bracket 3 and fixing bolts 31. The flange fixing bracket 3 is hinged to the outer wall of the flange slot 11. The flange fixing bracket 3 is provided on the side walls of both flange slots 11. The flange fixing bracket 3 and the flange slot 11 are fixedly connected by the fixing bolts 31. During operation, when the bellows 1 is installed in the pipeline system, the flange is inserted into the flange slot 11, and then the flange fixing bracket 3 is placed on the flange. The flange fixing bracket 3 and the flange slot 11 are locked by the fixing bolts 31, thus connecting the bellows 1 and the pipeline system. Through the above structure, the flange fixing bracket 3 and the flange slot 11 are combined and connected to the flange of the pipeline system to form a flange quick-connect structure, realizing the function of quickly connecting the bellows 1 and the flange. This solves the cumbersome steps of using multiple sets of screws to connect the bellows 1 and the flange, simplifies the operation steps of connecting the bellows 1 and the pipeline system, and improves the convenience of disassembly and assembly of the device.

[0023] like Figure 5As shown, the sealing assembly includes a sealing gasket 4; the sealing gasket 4 is fixedly connected to the side wall of the flange slot 11 away from the bellows 1; the sealing gasket 4 is provided on the side walls of both flange slots 11; during operation, when the flange is inserted into the flange slot 11, the side wall of the flange contacts the sealing gasket 4 and squeezes the sealing gasket 4, causing the sealing gasket 4 to deform and seal between the flange and the flange slot 11; through the above structure, the arrangement of the sealing gasket 4 in contact with the flange forms a sealing structure, realizing the function of sealing between the flange slot 11 and the flange, improving the sealing performance when the device is connected to the pipeline system, and reducing the leakage of the medium from the flange slot 11 and the flange.

[0024] like Figure 3 As shown, the anti-slip component includes anti-slip protrusions 5; the anti-slip protrusions 5 are fixedly connected to the side wall of the pressing block 22 away from the actuating frame 21; multiple sets of anti-slip protrusions 5 are provided on the side wall of the pressing block 22 and are evenly distributed on the side wall of the pressing block 22; during operation, when the pressing block 22 is squeezed, the anti-slip protrusions 5 increase the friction of the side wall of the pressing block 22; through the above structure, the anti-slip protrusions 5 increase the friction of the side wall of the pressing block 22, forming an anti-slip structure for the side wall of the pressing block 22, realizing the function of increasing the friction of the side wall of the pressing block 22, and reducing the slippage that occurs when the pressing block 22 is squeezed.

[0025] like Figure 5 As shown, the reinforcing component includes a reinforcing rib 6; the reinforcing rib 6 is fixedly connected to the side wall of the support rod 12 near the bellows 1; the reinforcing rib 6 is provided on the side walls of both support rods 12; during operation, the reinforcing rib 6 is provided on the side walls of the support rod 12 to increase the structural strength of the support rod 12, reduce the deformation of the support rod 12, and improve the service life of the support rod 12.

[0026] During operation, when the angle of the device needs to be adjusted, the release component disengages the self-locking component. Rotating the flange slot 11 positions both ends of the bellows 1 appropriately. The release component is then released, and the self-locking component fixes the angle of the bellows 1. The flange of the pipe to be installed is then inserted into the flange slot 11 and secured using the flange quick-connect assembly. The device is then installed in the piping system. The sealing component seals between the flange slot 11 and the flange. When the release component actuates, the pressure between the rotating plate 13 and the friction plate 14 decreases. The angle of the bellows 1 is adjusted according to the direction of the adjustment. When the rotating block 17 and support rod 12 are moved to the appropriate position, and the bellows 1 bends, the flange slot 11 drives the support rod 12 to swing, and a pair of rotating plates 13 rotate relative to each other. After the bellows 1 angle is adjusted, the release assembly resets, and the pair of rotating plates 13 are subjected to the pressure of the spring 16, which increases the friction between the pair of friction plates 14, restricting the rotation of the rotating plates 13 and support rod 12, thereby fixing the angle of the bellows 1. There is friction between the rotating block 17 and the flange slot 11, and the rotating block 17 remains stationary after rotating to the appropriate angle; the bellows When adjusting the angle of pipe 1, a pair of pressing blocks 22 are pressed towards the center. The pressing blocks 22 drive the actuating frame 21 and the pressing plate 2 to move away from each other, causing the pressing plate 2 to compress the spring 16, reducing the pressure between the friction plates 14 and lowering the friction between the friction plates 14, which facilitates the rotation of the support rod 12 and the rotating plate 13. After rotation, the pressing blocks 22 are released, and the spring 16 drives the pressing plate 2 and the actuating frame 21 to return to their original positions. When the bellows 1 is installed in the piping system, the flange is inserted into the flange slot 11, and then the flange fixing bracket 3 is placed on the flange. The flange mounting bracket 3 and flange slot 11 are locked together by fixing bolts 31, connecting the bellows 1 and the piping system. When the flange is inserted into the flange slot 11, the side wall of the flange contacts the sealing gasket 4 and squeezes the sealing gasket 4, causing the sealing gasket 4 to deform and seal the flange and flange slot 11. When the pressing block 22 is pressed, the anti-slip protrusions 5 increase the friction of the side wall of the pressing block 22. The reinforcing ribs 6 are set on the side wall of the support rod 12 to increase the structural strength of the support rod 12, reduce the deformation of the support rod 12, and improve the service life of the support rod 12.
