[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 This utility model provides a technical solution:

[0032] To address the problems existing in the prior art, this embodiment provides the following technical solution: a water supply and drainage pipe connection structure, comprising a pipe body 1; a docking mechanism, located on the upper and lower sides inside the connecting pipe 2, which allows for quick and precise docking of the pipe body 1 and the connecting pipe 2, facilitating subsequent installation; a reinforcing connection mechanism, located on the outside of the pipe body 1 and the connecting pipe 2, which performs secondary reinforcement after the pipe body 1 and the connecting pipe 2 are docked, greatly improving the stability of the connection; and an adjustable mechanism, located on the outside of the pipe body 1 and the connecting pipe 2, which allows adjustment of the distance between the first fixing block 8 and the second fixing block 16 according to the length of the pipe connection, further enhancing the stability of the connection between the pipe body 1 and the connecting pipe 2.

[0033] like Figure 5 and Figure 6 As shown, by inserting the pipe body 1 into the connecting pipe 2 from the left and right sides, since the connecting pipe 2 is symmetrically equipped with limit pins 3 on the upper and lower sides, and springs 4 are installed on the outside of the limit pins 3, the outside of the springs 4 is connected to the mounting block 5 for support. When the pipe body 1 is inserted into the connecting pipe 2, the springs 4 can be pulled upwards, so that the limit pins 3 move out of the pipe body 1. After the pipe body 1 is inserted into the connecting pipe 2, the springs 4 are released. The springs 4 will rebound and push the limit pins 3 to move inwards, so that they fit tightly with the pipe body 1. This can limit the pipe body 1, so that the pipe body 1 and the connecting pipe 2 can be connected quickly and accurately.

[0034] Then, the sealing ring 6 is put into the joint seam after the pipe body 1 and the connecting pipe 2 are connected. Then, the flange 7 is fitted to the sealing ring 6 from the top and bottom sides. Then, the flange 7 is fixed and limited by bolts. That is, the design of the sealing ring 6 and the flange 7 can improve the sealing of the connection between the pipe body 1 and the connecting pipe 2.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, after the pipe body 1 and the connecting pipe 2 are connected, the first fixing block 8 is fixed to the outside of the connecting pipe 2 from the top and bottom. Since the gear block 9 is installed at equal angles inside the first fixing block 8, the gear block 9 will fit tightly with the outside of the connecting pipe 2. The connecting rod 10 is installed on the outside of the first fixing block 8. The moving rod 11 is slidably set inside the connecting rod 10. The second fixing block 16 can be inserted into the outside of the pipe body 1, and then the moving rod 11 is inserted into the inside of the second fixing block 16, which can be firmly engaged with the second fixing block 16. At this time, the position of the second fixing block 16 can be adjusted according to the length of the pipe. The moving rod 11 will slide inside the connecting rod 10.

[0036] After the position is adjusted, the threaded rod 15 can be inserted into the positioning hole 14 inside the connecting rod 10 and the moving rod 11 for fixed positioning. At the same time, a threaded body 12 is provided on the outside of the moving rod 11, that is, the threaded body 12 can be threadedly connected to the limiting block 13, which can limit the position of the second fixing block 16. The connection between the first fixing block 8 and the second fixing block 16 can further enhance the stability of the connection between the pipe body 1 and the connecting pipe 2.

[0037] The working principle of this water supply and drainage pipe connection structure is as follows: the pipe body 1 and the connecting pipe 2 can be quickly and accurately connected first, and then a sealing ring 6 is installed at the joint to seal it. Then, a secondary fixed connection is made on the outside of the pipe body 1 and the connecting pipe 2, that is, a double fixed connection, which greatly improves the sealing performance of the connection between the pipe body 1 and the connecting pipe 2. At the same time, the secondary fixed seal can be adjusted, which greatly improves the design flexibility.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
