Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a connection structure for the outlet of a drainage unit in an urban drainage pipeline. Background Technology

[0002] In the field of urban drainage engineering technology, the connection node between the drainage unit outlet and the main drainage pipeline is a key component connecting decentralized drainage units and the municipal main drainage network. Its sealing reliability and adaptability directly determine the flood resistance, operational stability, and maintenance costs of the urban drainage system. Existing connection structures all consist of locking and sealing components, such as clamp-type and flange-type connection structures. Clamp-type connection structures use clamps as locking components and sealing rings as sealing components. An annular positioning groove needs to be machined at the pipe connection end. Tightening the clamp bolts causes the clamp to contract radially, compressing the sealing ring to produce elastic deformation and achieve a seal. Flange-type connection structures use flanges as locking components and gaskets as sealing components. Bolts axially tighten the flange, compressing the gasket to fill the end face gap and achieve a seal. However, the existing connection structures still have the following drawbacks: 1. The fixed structure of the locking component leads to poor versatility and inability to adapt to pipes of different diameters; 2. The sealing component relies solely on a single elastic deformation, lacking an auxiliary sealing mechanism, resulting in poor reliability. Utility Model Content

[0023] Please see the appendix Figure 1 -Appendix Figure 5This utility model provides an embodiment of a drainage unit outlet connection structure for urban drainage pipelines, including a locking component 1. The locking component 1 includes a housing 11, on which an installation groove 12 is provided. An adjusting ring 16 is threaded into the installation groove 12. A conical groove 19 is provided on the adjusting ring 16, and multiple wedges 110 are provided in the conical groove 19. A second through groove 15 is provided in the installation groove 12 at the position corresponding to the wedges 110, and the wedges 110 are slidably connected in the second through groove 15. A slider 111 is fixedly connected to the wedges 110. A spring 112 is provided on one side of the wedges 110. A receiving groove 13 is provided in the installation groove 12 at the position corresponding to the spring 112, and one end of the spring 112 is provided in the receiving groove. Inside 13, the other end is set on the slider 111. A first clamping block 113 is fixedly connected to the wedge 110. A fixing rod 114 is fixedly connected to the first clamping block 113. A second clamping block 115 is slidably connected to the fixing rod 114. A screw 116 is hinged to the second clamping block 115 and threadedly connected to the first clamping block 113. Rotating the adjusting ring 16 on the housing 11 allows the adjusting ring 16 to rotate and move inward within the mounting groove 12, pushing the wedge 110 through the conical groove 19. The wedge 110 moves radially towards the pipe 3 along the second through groove 15. The slider 111 on the wedge 110 slides accordingly and compresses the spring 112. The first clamping block 113 on the wedge 110 moves accordingly. The first clamping block 113 is connected to the screw 116 and the fixing rod 114 drive the second clamping block 115 to move until the bottom of the first clamping block 113 and the second clamping block 115 are in contact with the inner wall of the groove 4. At this time, the screw 116 can be tightened to drive the second clamping block 115 to slide along the fixing rod 114 until the first clamping block 113 and the second clamping block 115 clamp and lock the two pipes 3, thus completing the connection of the pipes 3. The fixing rod 114 is used to guide the second clamping block 115. The spring 112 in the receiving groove 13 is used to provide a reset elastic force for the slider 111, so that when the adjusting ring 16 is adjusted outward, the wedge block 110 can automatically reset. A first through groove 14 is opened in the receiving groove 13 at the position corresponding to the slider 111, and the slider 111 is slidably connected in the first through groove 14. A through groove 14 is used to accommodate the slider 111; a sleeve 17 is fixedly connected to the adjusting ring 16, and multiple handle grooves 18 are evenly distributed on the sleeve 17. The handle grooves 18 and the sleeve 17 form a handle, which facilitates the rotation of the adjusting ring 16; a sealing component 2 is provided inside the locking component 1. The sealing component 2 includes a sealing ring 21, an annular groove 22, a sealing lip 23, a connecting ring 24, a spring 25, and a retaining ring 26. An annular groove 22 is opened in the sealing ring 21, and the connecting ring 24 is sleeved in the annular groove 22. Multiple springs 25 are evenly distributed on the outer walls of both sides of the connecting ring 24. The connecting ring 24, the springs 25, and the retaining ring 26 form an elastic element. The sealing ring 21 accommodates the elastic element through the annular groove 22. The springs 25 can force the sealing ring 21 to fit more tightly against the end face of the pipe 3.Both sides of the annular groove 22 are provided with sealing lips 23, and the sealing lips 23 are fixedly connected to the sealing ring 21. The sealing lips 23 can improve the sealing effect at the connection position of the pipe 3. A retaining ring 26 is provided on one side of the sealing ring 21, and the retaining ring 26 is fixedly connected to the spring piece 25. The spring piece 25 provides elasticity to the retaining ring 26, and the retaining ring 26 can make the sealing lips 23 fit against the inner wall of the pipe 3.

[0024] Working principle: When using this utility model, if it is necessary to connect two pipes 3, the locking component 1 can be installed on the pipe 3 first, and then the sealing component 2 can be placed between the two pipes 3 so that the sealing lip 23 fits inside the pipe 3. Then, the locking component 1 can be adjusted to fit the diameter of the pipe 3. Specifically, the adjusting ring 16 on the housing 11 is rotated. The adjusting ring 16 rotates and moves inward in the mounting groove 12, pushing the wedge 110 through the conical groove 19. The wedge 110 moves radially towards the pipe 3 along the second through groove 15. The slider 111 on the wedge 110 slides in the first through groove 14 and compresses the spring 112. The first clamping block 113 on the wedge 110 moves accordingly. The first clamping block 113 drives the second clamping block 115 to move accordingly through the screw 116 and the fixing rod 114 until the bottom of the first clamping block 113 and the second clamping block 115 are in contact with the inner wall of the groove 4. At this time, the screw 11 can be tightened. 6. Drive the second clamping block 115 to slide along the fixed rod 114 until the first clamping block 113 and the second clamping block 115 clamp and lock the two pipes 3, thereby completing the connection of the pipes 3; wherein, the spring 112 is used to provide the return elastic force for the slider 111, so that when the adjusting ring 16 is adjusted outward, the wedge block 110 can automatically return to its original position. The receiving groove 13 is used to receive the spring 112. The handle groove 18 and the sleeve 17 form a handle to facilitate the rotation of the adjusting ring 16. The sealing ring 21 is used to seal the end faces of the two pipes 3. The sealing lip 23 further improves the sealing effect at the connection position of the pipes 3. The connecting ring 24, the spring piece 25 and the retaining ring 26 form an elastic element. The sealing ring 21 receives the elastic element through the annular groove 22. The spring piece 25 provides elastic force to the retaining ring 26. The spring piece 25 can force the sealing ring 21 to fit more tightly against the end face of the pipe 3. The retaining ring 26 can make the sealing lip 23 fit against the inner wall of the pipe 3.
