[0011] Furthermore, there are three threaded holes, which are evenly and equidistantly arranged in a linear array, and the threaded holes are adapted to the fixing bolts.

[0012] By adopting the above technical solution, the three threaded holes make the installation process more flexible. When the angle and position of the eccentric tube body need to be adjusted, the fixing bolts can be loosened first, adjusted, and then retightened.

[0013] Furthermore, there are a plurality of limiting grooves, which are evenly and equidistantly arranged, and the clamping blocks are adapted to the limiting grooves.

[0014] By adopting the above technical solution and setting a plurality of limit grooves, multiple positioning points can be provided for the clamping block, so that the eccentric tube body can be more stably fixed on the shell after adjusting the angle and position.

[0015] Furthermore, the bottom of the eccentric tube body is fixedly connected to the movable plate, and the eccentric tube body rotates along with the movable plate.

[0016] By adopting the above technical solution, by fixedly connecting the bottom of the eccentric tube body with the movable plate, the relative position between the two can be ensured to remain unchanged, and the stability of the structure can be maintained to prevent loosening or deformation even when subjected to external force or pressure.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] The following describes an embodiment of the present invention based on its overall structure.

[0029] An eccentric reducing elbow, such as Figure 1-Figure 4 As shown, it includes an eccentric reducer elbow body 1 and an adjustment mechanism 2, the adjustment mechanism 2 includes a shell 201, a limit groove 209 is provided on the outer surface of the shell 201, a through hole 211 is provided at the bottom of the shell 201, a slide groove 202 is provided on the outer side of the through hole 211, and a slider 203 is engaged and slidably engaged with the slide groove 202, and a movable plate 204 is fixedly connected to the top of the slider 203;

[0030] The top of the movable plate 204 is fixedly connected to a fixed block 205, a threaded hole 208 is opened on the top of the fixed block 205, a sleeve block 206 is sleeved on the fixed block 205, a fixing bolt 207 is provided on the top of the sleeve block 206, and a clamping block 210 is provided at the bottom of the sleeve block 206. The outer shell 201 provides protection for the adjustment mechanism to prevent the internal parts from being affected by the external environment, improve the structural stability of the entire elbow, and enable it to withstand greater internal pressure and external loads. The sleeve block 206 is connected to the fixed block 205 by the fixing bolt 207 to form an adjustable support structure.

[0031] See Figure 1 、 Figure 4 The eccentric reducer elbow body 1 includes a large-diameter joint 101, an eccentric tube body 102 and a small-diameter joint 103. The large-diameter joint 101 and the small-diameter joint 103 are internally provided with threads. The threaded connection forms a tight sealing surface by tightening the threads, which can effectively prevent fluid leakage and improve the sealing performance of the pipeline system. The small-diameter joint 103 can match downstream pipelines of different specifications and sizes through threaded connection, thereby increasing the application range of the eccentric reducer.

[0032] See Figure 2 、 Figure 3 The shell 201 and the slide groove 202 are both elliptical in shape, and the through hole 211 is adapted to the large-diameter joint 101. The adaptation of the through hole 211 to the large-diameter joint 101 can ensure a tight connection between the two, which helps to prevent fluid leakage and gas penetration, and ensure the sealing and safety of the pipeline system. The elliptical shell 201 and the slide groove 202 allow users to adjust the eccentric angle of the joint according to actual conditions.

[0033] See Figure 1 There are three threaded holes 208, and the three threaded holes 208 are evenly spaced and arranged in a linear array. The threaded holes 208 are adapted to the fixing bolts 207. The three threaded holes 208 make the installation process more flexible. When the angle and position of the eccentric tube body 102 need to be adjusted, the fixing bolts 207 can be loosened first, and then retightened after adjustment. The adaptation of the threaded holes 208 and the fixing bolts 207 can ensure a tight connection between the two and prevent loosening during use.

[0034] See Figure 1There are several limiting grooves 209, and the limiting grooves 209 are evenly and equidistantly arranged. The clamping block 210 is adapted to the limiting grooves 209.

By fixing the bottom of the eccentric tube body 102 to the movable plate 204, the relative position between the two can be ensured to remain unchanged. Even when subjected to external force or pressure, the stability of the structure can be maintained to prevent loosening or deformation. The eccentric tube body 102 can rotate with the rotation of the movable plate 204, which makes it possible to flexibly adjust the angle and position of the eccentric tube body 102 according to actual needs during installation and use to adapt to different pipeline connection requirements.

[0036] See Figure 1 、 Figure 4 A rubber sealing layer is provided inside the chute 202, and the outer shell 201 and the movable plate 204 are made of carbon steel. The rubber sealing layer has good elasticity and sealing performance, which can effectively prevent the leakage of fluid between the chute 202 and the slider 203, ensuring the sealing effect of the eccentric reducer when connecting the pipe. Carbon steel has high strength and hardness, and can withstand large pressure and impact loads, ensuring the structural stability and safety of the eccentric reducer under complex working conditions.

[0037] The implementation principle of the present invention is as follows: first, by rotating the movable plate 204, the slider 203 slides in the slide groove 202, so that the eccentric tube body 102 is rotated to a suitable installation angle and position, and then the sleeve block 206 is pushed inward to make the clamping block 210 clamped with the limit groove 209, and then the sleeve block is tightened and fixed by the fixing bolt 207.

[0038] Parts not involved in the present invention are the same as those in the prior art or can be implemented by using the prior art, and will not be described in detail here.
