[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses a connection structure for a concrete drainage pipe. (Refer to...) Figure 1 , Figure 2 and Figure 4 A connection structure for a concrete drainage pipe includes two pipe bodies 1 and a base 2. The two pipe bodies 1 are respectively fitted inside the base 2 on both sides. A sealing groove 101 is opened at one end of the pipe body 1, and a sealing ring 102 is fixedly installed at the other end of the pipe body 1. The sealing ring 102 is used in conjunction with the sealing groove 101. A connecting mechanism 3 is provided on the surface of the pipe body 1, and the connecting mechanism 3 is used in conjunction with the base 2. The connecting mechanism 3 includes two positioning sleeves 31, which are slidably fitted onto the surfaces of the two tube bodies 1. One end of the tube body 1 is provided with a threaded groove 3201, and a top plate 32 is threadedly fitted inside the threaded groove 3201. A slot 3202 is provided on the side of the positioning sleeve 31 opposite to the threaded groove 3201, and one end of the top plate 32 is inserted into the inside of the slot 3202. A connecting component 33 is provided on the surface of the tube body 1. The connecting component 33 is used in conjunction with the positioning sleeve 31, and the positioning sleeve 31 is inserted into the inside of the base 2. When pipe docking is required, screw the top plate 32 into the threaded groove 3201, then dock the positioning sleeve 31 with the pipe body 1, and insert one end of the top plate 32 into the slot 3202. Then, dock the two positioning sleeves 31 through the connecting component 33, and support the position of the positioning sleeves 31 through the top plate 32, thereby docking the two pipe bodies 1. Then, set the two pipe bodies 1 in the base 2, and make the positioning sleeves 31 snap into the inside of the base 2, thus completing the docking of the pipe bodies 1 and making the docking position of the pipe bodies 1 more stable.

[0018] Reference Figure 2 and Figure 4 A protrusion 3101 is fixedly installed on the surface of the pipe body 1, and a groove 3102 is provided on the inner wall of the positioning sleeve 31. The protrusion 3101 and the groove 3102 are used in conjunction. A support block 3104 is fixedly installed inside the base 2, and a support groove 3103 is provided on the side of the positioning sleeve 31 opposite to the base 2. The support block 3104 and the support groove 3103 are used in conjunction. When the positioning sleeve 31 is connected to the pipe body 1, by inserting the protrusion 3101 into the groove 3102, the position of the positioning sleeve 31 can be stabilized by the protrusion 3101 and the groove 3102, so as to prevent the positioning sleeve 31 from rotating on the surface of the pipe body 1, thereby ensuring the stability of the position of the positioning sleeve 31. By inserting the support block 3104 into the support groove 3103, the position of the positioning sleeve 31 inside the base frame can be stabilized by the support block 3104 and the support groove 3103, so as to prevent the positioning sleeve 31 from rotating inside the base frame and affecting the stability of the position of the pipe body 1.

[0019] Reference Figure 2 and Figure 3 The connecting component 33 includes a connecting frame 3301, which is disposed on the surface of the pipe body 1. A screw 3302 is slidably sleeved inside the connecting frame 3301. One end of the screw 3302 passes through the positioning sleeve 31 and is slidably connected to the inner cavity of the positioning sleeve 31. A nut 3303 is threaded onto one end of the screw 3302. The nut 3303 abuts against one side of the positioning sleeve 31. By connecting the connecting frame 3301 to the pipe body 1, inserting the screw 3302 into the interior of the connecting frame 3301, and then allowing one end of the screw 3302 to pass through the positioning sleeve 31, and connecting the nut 3303 to one end of the screw 3302, so that the nut 3303 abuts against one side of the positioning sleeve 31, the positioning sleeve 31 is positioned to stabilize the position of the positioning frame on the surface of the pipe body 1.

[0020] Reference Figure 2 and Figure 3Both the connecting frame 3301 and the positioning sleeve 31 have openings 3304 on their surfaces, and the screw 3302 is used in conjunction with the openings 3304. By opening the openings 3304 on the surfaces of the connecting frame 3301 and the positioning sleeve 31, the screw 3302 can be connected to the connecting frame 3301 and the positioning sleeve 31 through the openings 3304.

[0021] Reference Figure 2 and Figure 3 A connecting block 3305 is fixedly connected to the side of the connecting frame 3301 opposite to the pipe body 1. A connecting groove 3306 is opened on the surface of the pipe body 1. The surface of the connecting block 3305 is slidably connected to the inner cavity of the connecting groove 3306. A fixing frame 3307 is fixedly installed on one side of the connecting frame 3301. A bolt 3308 is rotatably connected to one side of the fixing frame 3307. One end of the bolt 3308 passes through the fixing frame 3307 and is threadedly connected to the pipe body 1. By inserting the connecting block 3305 into the interior of the connecting groove 3306, the connecting frame 3301 is made to fit against the surface of the pipe body 1. Then, one end of the bolt 3308 passes through the fixing frame 3307 and is threadedly connected to the pipe body 1 to position the connecting frame 3301.

[0022] Working principle: When pipe body 1 needs to be connected, screw the top plate 32 into the threaded groove 3201, then connect the positioning sleeve 31 to the pipe body 1, and insert one end of the top plate 32 into the slot 3202. Then, attach the connecting bracket 3301 to the surface of the pipe body 1, and insert the connecting block 3305 into the connecting groove 3306. Then, thread one end of the bolt 3308 through the fixing bracket 3307 and connect it to the pipe body 1 to position the connecting bracket 3301. Then, insert the screw 3302 into the connecting bracket 3301 through the opening 3304, and let one end of the screw 3302 pass through the positioning sleeve 31. Connect the nut 3303 to one end of the screw 3302, so that the nut 3303 abuts against one side of the positioning sleeve 31, thereby positioning the positioning sleeve 31 and stabilizing the two positioning sleeves 3. Positioning the two pipe bodies 1 at position 1 completes the docking of the two pipe bodies 1. The sealing ring 102 and sealing groove 101 seal the docking position of the pipe bodies 1. Then, positioning sleeve 31 and pipe body 1 are placed in the base frame, so that positioning sleeve 31 is snapped into the base 2 and support block 3104 is inserted into the support groove 3103. The support block 3104 and support groove 3103 can stabilize the position of positioning sleeve 31 inside the base frame, thereby stabilizing the position of pipe body 1 inside the base frame. The protrusion 3101 and groove 3102 can effectively stabilize the position of pipe body 1 inside positioning sleeve 31, thereby completing the docking of pipe body 1 and making the docking position of pipe body 1 more stable. The base frame, top plate 32 and positioning sleeve 31 support the middle position of pipe body 1, preventing damage to the docking position of pipe body 1 in case of settlement, accidental displacement or other situations.
