[0021] 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.
[0022] Please see Figure 1-5 One embodiment provided by this utility model:
[0023] A highly adaptable sewage valve elbow includes an elbow body 1. Flanges 11 are fixedly connected to both ends of the elbow body 1. A sealing gasket 12 is fixedly connected inside flange 11. A bellows 3 is provided at one end of the elbow body 1. A flange 31 is fixedly connected to one end of the bellows 3. A flange 32 is fixedly connected to the other end of the bellows 3. Fixing bolts 2 are rotatably connected inside flange 31 and flange 11. Nuts 21 are rotatably connected to the surface of the fixing bolts 2. A sealing gasket 12 is provided on the surface of flange 31 and flange 32. Adjustment structure 4 includes a fixed rod 41, with a connecting rod 42 rotatably connected inside the fixed rod 41. A handwheel 43 is fixedly connected to one end of the connecting rod 42, and a worm gear 44 is fixedly connected to the other end of the connecting rod 42. A worm wheel 45 meshes with the surface of the worm gear 44, and a rotating rod 46 is fixedly connected inside the worm wheel 45. Limit blocks 47 are fixedly connected to both ends of the rotating rod 46. An adjusting rod 48 is fixedly connected to the surface of the rotating rod 46, and a protractor 49 is fixedly connected to the surface of the adjusting rod 48. The surface of the fixed rod 41 is opened... The device has a rotating groove 410 and an adjusting structure 4. Rotating the handwheel 43 drives the connecting rod 42 to rotate, causing the worm gear 44 and worm wheel 45 to mesh and thus drive the rotating rod 46 to rotate. The rotating rod 46 is fixed to the adjusting rod 48, causing the fixed rod 41 and the adjusting rod 48 to rotate relative to each other. The bellows 3 is adjusted in angle via flanges 31 and 32 connected to both, and the angle is precisely adjusted using a protractor 49. The self-locking property of the worm gear 44 and worm wheel 45 ensures the stability of the fixed rod 41 and the adjusting rod 48. The angle between the two will not change when subjected to external force, and the angle of the bellows 3 can be adjusted so that the elbow body 1 can adapt to various usage requirements. It is equipped with a sealing gasket 12, fixing bolts 2, flange 2 31 and flange 3 32. The flange 1 11 and flange 2 31 are fixed to each other by the cooperation of fixing bolts 2 and nuts 21, thereby connecting the elbow body 1 and the bellows 3. It can be added as needed, and the installation and disassembly are relatively convenient. The sealing gasket 12 increases the sealing performance of the connection between the elbow body 1 and the bellows 3.
[0024] Furthermore, the sealing gasket 12 is convex in shape and is made of rubber. The surface of the sealing gasket 12 is fixedly connected to the flange 11, and the protrusions on the surface of the sealing gasket 12 are fixedly connected to the inner walls at both ends of the elbow body 1. The sealing gasket 12 increases the sealing performance between the elbow body 1 and the bellows 3, resulting in good sealing performance.
[0025] Furthermore, the surfaces of flange 11, flange 21 and flange 32 are all provided with threaded grooves. The fixing bolts 2 are rotatably connected in the threaded grooves. The flange 11 and flange 21 are fixed to each other by the cooperation of the fixing bolts 2 and nuts 21, thereby connecting the elbow body 1 and the bellows 3. It can be added as needed, and the installation and disassembly are relatively convenient.
[0026] Furthermore, two sets of fixing rods 41 are provided, and the two sets of fixing rods 41 are fixedly connected to flange 2 31. The adjusting rod 48 is fixedly connected to flange 3 32. The fixing rods 41 and adjusting rods 48 are arranged crosswise and can rotate relative to each other. By rotating and adjusting the fixing rods 41 and adjusting rods 48, the flanges 2 31 and flange 3 32 at both ends of the bellows 3 can be moved, thereby adjusting the bending angle of the bellows 3. Together with the elbow body 1, it can adapt to various usage requirements.
[0027] Furthermore, the rotating rod 46 is rotatably connected in the rotating groove 410, and both ends of the rotating rod 46 pass through the fixed rod 41 through the rotating groove 410. The adjusting rod 48 is rotatably connected between the two sets of fixed rods 41. Rotating the handwheel 43 drives the connecting rod 42 to rotate, and the worm gear 44 and the worm wheel 45 mesh with each other, thereby driving the rotating rod 46 to rotate. The rotating rod 46 and the adjusting rod 48 are fixed to each other, thereby causing the fixed rod 41 and the adjusting rod 48 to rotate relative to each other.
[0028] Furthermore, the diameter of the limiting block 47 is larger than the inner diameter of the rotating groove 410. By cooperating with the rotating groove 410, the limiting block 47 limits the rotating rod 46 when it rotates, preventing it from sliding out of the rotating groove 410, so that it can only rotate within the rotating groove 410 and will not move.
[0029] Furthermore, the protractor 49 has a scale on its surface. When adjusting the angle, the protractor 49 is fixed to the surface of the adjusting rod 48. The angle between the adjusting rod 48 and the fixed rod 41 can be observed directly through the scale, allowing for precise adjustment of the angle.
[0030] Working principle: In use, rotating the handwheel 43 drives the connecting rod 42 to rotate. The worm gear 44 and worm wheel 45 mesh with each other, thereby driving the rotating rod 46 to rotate. The rotating rod 46 is fixed to the adjusting rod 48, which in turn causes the fixed rod 41 and the adjusting rod 48 to rotate relative to each other. The flanges 31 and 32 connected to both drive the bellows 3 to adjust the angle. The protractor 49 is used to achieve precise angle adjustment. The self-locking property of the worm gear 44 and worm wheel 45 ensures that the angle between the fixed rod 41 and the adjusting rod 48 will not change when subjected to external force. The angle of the bellows 3 is adjusted so that the elbow body 1 can adapt to various usage requirements. The flange 11 and flange 21 are fixed to each other by the cooperation of the fixing bolts 2 and nuts 21, thereby connecting the elbow body 1 and the bellows 3. It can be added as needed. The maximum and minimum adjustment angle of the bellows 3, that is, the maximum and minimum included angle between the fixing rod 41 and the adjusting rod 48, are related to the length of the bellows 3. At the same time, since the bellows 3 has a certain thickness, the fixing rod 41 and the adjusting rod 48 cannot overlap, that is, the minimum included angle between the fixing rod 41 and the adjusting rod 48 is greater than zero degrees.
[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
