[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , the present invention provides a technical solution: a reinforced concrete drainage pipe with a rubber ring groove, including a pipe body 1, one end of the pipe body 1 is provided with a socket 2, and the end of the pipe body 1 far from the socket 2 is provided with a socket 101. When it is necessary to splice the ends of multiple pipe bodies 1 for use, the socket 101 on one pipe body 1 is inserted into the socket 2 on another pipe body 1. A rubber ring groove 3 is formed on the surface of the end of the pipe body 1 far from the socket 2. A middle rib is formed between the two rubber ring grooves 3, and a water passing hole 102 is arranged on the middle rib. The cross-section of the rubber ring groove 3 is a semi-circular arc structure. A sealing rubber ring 4 is arranged in the rubber ring groove 3. Due to the semi-circular arc structure of the rubber ring groove 3, the groove wall has a smooth transition, and the opening edge of the rubber ring groove 3 will not be damaged during production and manufacturing, ensuring the interface sealing effect when the pipe body 1 is butt-jointed and installed, and it is not easy to leak water. One end of the pipe body 1 close to the rubber ring groove 3 is integrally provided with a docking column 5 at its edge. A locking groove 6 is formed on the surface of the docking column 5. When the socket 101 on one pipe body 1 is inserted into the socket 2 on another pipe body 1, at this time, the docking column 5 is inserted into the alignment groove 7 on the inner wall of the socket 2;

[0023] An alignment groove 7 is formed on the inner wall of the socket 2. The docking column 5 is located in the alignment groove 7. A storage groove 8 is formed on the inner wall of the alignment groove 7. A baffle 9 is arranged in the storage groove 8. A driving spring 10 is arranged between the baffle 9 and the inner wall of the storage groove 8. When the docking column 5 is inserted into the alignment groove 7, at this time, the docking column 5 will come into contact with the baffle 9 in the alignment groove 7. The cross-section of the baffle 9 is an "L" - shaped structure. The baffle 9 and the storage groove 8 form a telescopic structure through the driving spring 10. Therefore, the docking column 5 inserted into the alignment groove 7 will push the baffle 9 to retract into the storage groove 8;

[0024] On the inner wall of the socket 2, there is also a vertical groove 11. In the initial state, the baffle 9 blocks and closes the opening position of the vertical groove 11. A locking post 12 is also arranged in the vertical groove 11. When the docking post 5 pushes the baffle 9 to retract into the receiving groove 8, at this time the vertical groove 11 is no longer blocked by the baffle 9. A return spring 13 is arranged between the locking post 12 and the vertical groove 11. The locking post 12 and the vertical groove 11 form a telescopic structure through the return spring 13. After the vertical groove 11 is no longer blocked by the baffle 9, the return spring 13 will push the locking post 12 to extend out of the vertical groove 11 until the locking post 12 is inserted into the locking groove 6. At this time, the connection between the locking post 12 and the docking post 5 is completed. Therefore, the docking post 5 is installed in the alignment groove 7, and further, the stable splicing installation between two different pipe bodies 1 is also completed through the cooperation between the locking post 12 and the docking post 5.
