[0028] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0029] Example 1

[0030] like Figure 1-3 As shown, this embodiment provides a sewage pipe docking assembly, which includes a first flange 210 and a second flange 220 respectively arranged at the adjacent pipe docking ends; a fitting 110 is provided at the first flange 210, and a plug-in component 120 that is matched with the fitting 110 is provided at the second flange 220; a plurality of snap-fit ​​modules 320 are equidistantly provided at the outer wall of the plug-in component 120, and a sliding groove 310 corresponding to the plurality of snap-fit ​​modules 320 is provided at the outer wall of the fitting 110, and a fixing component 360 for matching with the snap-fit ​​module 320 is provided in the sliding groove 310.

[0031] When the staff in this embodiment dock the pipes, they connect the butt ends of the pipes to be docked to the first flange 210 and the second flange 220 respectively. After the connection is completed, the fitting 110, the plug-in connector 120 and the corresponding first flange 210 and the second flange 220 are positioned first, and then the fitting 110 and the plug-in connector 120 are preliminarily fixed. After the preliminarily fixed, the adjacent pipes are fine-tuned and finally fixed by the fixing member 360. Compared with the prior art, the utility model can quickly dock the adjacent pipes, avoid the offset in the process of pipe docking, reduce the difficulty of connecting the eccentric pipe axis, improve the installation efficiency of the pipe docking, and shorten the pipe installation construction time;

[0032] The diameters of the first flange 210 and the second flange 220 can be adapted according to the diameter of the pipeline to adapt to the connection of pipelines with different diameters, thereby improving the application scope of the component.

[0033] Combination Figure 1-3 As shown, in this embodiment, a positioning cavity 240 for positioning the first flange 210 and the second flange is formed between the mating piece 110 and the plug-in piece 120, and the first flange 210 and the second flange are in contact with each other to form a contact surface 230 for docking the pipe, and a sealing ring 270 is provided at the contact surface 230; a plurality of positioning blocks 250 for quickly positioning the first flange 210 and the second flange are equidistantly provided on the inner wall of the positioning cavity 240, and a snap-in groove 260 corresponding to the positioning block 250 is provided at the joint of the first flange 210 and the second flange 220 in the positioning cavity 240.

[0034] After the mating piece 110 and the plug-in connector 120 are connected in the present embodiment, a positioning cavity 240 is formed between the mating piece 110 and the plug-in connector 120. The positioning cavity 240 squeezes the first flange 210 and the second flange 220, so that the contact surface 230 between the first flange 210 and the second flange 220 fits tightly, reducing the gap between the contact surface 230 formed by the first flange 210 and the second flange 220. At the same time, the sealing ring 270 performs a secondary seal on the contact surface 230. Through the positioning cavity 240 and the sealing ring 270, the first flange 210 and the second flange 220 are pressed. The contact surface 230 of the first flange 210 and the second flange 220 is doubly sealed to prevent leakage at the pipe docking point and improve the quality of the device docking with the pipe; when the positioning cavity 240 is positioning the first flange 210 and the second flange 220, the positioning block 250 will penetrate into the clamping groove 260 on the first flange 210 and the second flange 220, so that the first flange 210 and the second flange 220 can be quickly positioned, and the first flange 210 and the second flange 220 are prevented from rotating in the positioning cavity 240, thereby improving the stability of the device docking with the pipe.

[0035] Combination Figure 2-5 As shown, in this embodiment, the locking module 320 includes a locking block 130, and tightening grooves 510 for moving the locking block 130 are equidistantly provided on the side walls of the connector 120. The locking block 130 includes a sliding portion 140 sliding inside the tightening groove 510 and a tightening portion 150 engaged with the sliding groove 310; the locking module 320 also includes a guide rod 530 arranged in the tightening groove 510 along the sliding direction of the tightening portion 150, and a guide groove 540 for sliding with the guide rod 530 is provided at the tightening portion 150; the locking module 320 also includes a spring 520 sleeved on the outside of the guide rod 530 for pushing the tightening portion 150 to slide.

[0036] In this embodiment, the staff makes the sliding part 140 on the locking block 130 slide inside the tightening groove 510, adjusts the tightening part 150 to the position corresponding to the sliding groove 310, and then docks the matching piece 110 with the plug-in piece 120. During the docking process, the tightening part 150 on the locking block 130 will slide and engage with the inner wall of the sliding groove 310, thereby pre-fixing the plug-in piece 120 corresponding to the locking block 130 and the matching piece 110 corresponding to the sliding groove 310; when the sliding part 140 slides inside the tightening groove 510, the guide groove 540 on the guide rod 530 will slide with the surface of the guide rod 530, and the sliding direction of the sliding part 140 is adjusted. The guide prevents the sliding part 140 from being offset during the sliding process inside the guide groove 540, which may cause the tightening part 150 to be skewed, thereby improving the stability of the pre-fixation of the tightening part 150 and the sliding groove 310; when the tightening part 150 slides and engages with the inner wall of the sliding groove 310, the spring 520 outside the guide rod 530 will push the sliding part 140, pressing the tightening part 150 into the sliding groove 310, so that the tightening part 150 is located inside the sliding groove 310, and the tightening part 150 is pressed and driven by the spring 520, so that the tightening part 150 is automatically stuck into the sliding groove 310, thereby realizing the rapid positioning of the mating part 110 and the plug-in part 120.

[0037] Combination Figure 2-3 As shown, in this embodiment, the inner wall of the sliding groove 310 is provided with a docking groove 340 for limiting the tightening part 150, and the tightening part 150 is provided with a docking block 330 corresponding to the docking groove 340; the fixing member 360 includes a threaded column 350 provided on the inner wall of the sliding groove 310 for fixing the tightening part 150.

[0038] After the tightening part 150 in this embodiment slides into the sliding groove 310, the docking block 330 on the tightening part 150 will engage with the docking groove 340 in the sliding groove 310, thereby engaging and fixing the tightening part 150 and the sliding groove 310, thereby improving the stability of the pre-fixation between the engaging block 130 and the inside of the sliding groove 310; after the tightening part 150 and the sliding groove 310 are relatively fixed in position, the staff fixes the tightening part 150 in the sliding groove 310 through the threaded column 350, thereby enhancing the stability of the fixation between the tightening part 150 and the sliding groove 310, and further improving the stability of the device docking.

[0039] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.
