[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the scope of protection of the present invention.

[0027] As Figure 1 shown, this embodiment proposes a seamless connection structure for municipal pipelines, including a first pipeline body 1. A second pipeline body 2 is arranged on one side of the first pipeline body 1, and an adjusting component 3 is arranged at the connection between the first pipeline body 1 and the second pipeline body 2.

[0028] As Figure 1 and Figure 2As shown, one end of the first pipe body 1 is provided with an annular groove 11. A first waterproof ring 111 is fixedly connected to the bottom inner wall of the annular groove 11. A clamping groove 112 is penetrated and opened on the side wall of the annular groove 11. A through groove 113 is also penetrated and opened on the side wall of the annular groove 11. One end of the second pipe body 2 is fixedly connected with an annular block 21. A second waterproof ring 211 is fixedly connected to one end of the annular block 21. A clamping block 212 is fixedly connected to the outer surface of the annular block 21. A threaded groove 213 is opened on the outer surface of the annular block 21. The annular block 21 is slidably connected with the annular groove 11. The clamping block 212 and the clamping groove 112 are clamped and slidably connected with each other. The threaded groove 213 is communicated with the through groove 113, and the two are fixedly connected by an externally connected threaded rod. The first waterproof ring 111 and the second waterproof ring 211 are used together to prevent the water liquid inside the first pipe body 1 and the second pipe body 2 from overflowing through the connection part of the first pipe body 1 and the second pipe body 2. The existence of the clamping groove 112 and the clamping block 212 is convenient for limiting the first pipe body 1 and the second pipe body 2, that is, preventing the two from rotating in different states. The existence of the threaded groove 213 and the through groove 113 is convenient for fixedly connecting the two by threads, that is, fixedly connecting the first pipe body 1 and the second pipe body 2.

[0029] As Figure 3 shown, the adjusting assembly 3 includes a first auxiliary component 31 and a second auxiliary component 32 arranged on the outer surfaces of the first pipe body 1 and the second pipe body 2. The structures of the first auxiliary component 31 and the second auxiliary component 32 are symmetrical. The first auxiliary component 31 is used for auxiliary fixed fine adjustment of one side of the connection part of the first pipe body 1 and the second pipe body 2. The second auxiliary component 32 is used for auxiliary fixed fine adjustment of the other side of the connection part of the first pipe body 1 and the second pipe body 2.

[0030] As Figure 4As shown, the first auxiliary component 31 includes a U-shaped bracket 311 provided on the outer surfaces of the first pipe body 1 and the second pipe body 2. An extension fixing member 3111 is fixedly connected to the outer side of the U-shaped bracket 311. Square blocks 3112 are fixedly connected to both sides of the U-shaped bracket 311. A circular groove 31121 is formed through one side of the square block 3112. A first telescopic rod 3113 and a second telescopic rod 3114 are fixedly connected to the inner side of the U-shaped bracket 311. A first T-shaped groove 3115 and a second T-shaped groove 3116 are formed on the inner side wall of the U-shaped bracket 311. The first telescopic rod 3113 is located above the second telescopic rod 3114, and the first T-shaped groove 3115 is located above the second T-shaped groove 3116. The first auxiliary component 31 and the second auxiliary component 32 are fixedly connected through the circular grooves 31121 formed in the two square blocks 3112. The extension fixing member 3111 is used to keep the U-shaped bracket 311 fixed by an external object, that is, to prevent the U-shaped bracket 311 from shaking when finely adjusting the first pipe body 1 and the second pipe body 2. The presence of the square block 3112 and the circular groove 31121 facilitates the fixed connection between the first auxiliary component 31 and the second auxiliary component 32, that is, assembling the first auxiliary component 31 and the second auxiliary component 32 into a whole.

[0031] As Figure 5 shown, a first pushing member 312 and a second pushing member 313 are slidably connected to the inner side of the U-shaped bracket 311. The first pushing member 312 and the second pushing member 313 have the same structure. The first pushing member 312 is located at the upper end of the second pushing member 313. The first pushing member 312 is located on the outer surface of the first pipe body 1, and the second pushing member 313 is located on the outer surface of the second pipe body 2. The first pushing member 312 includes a semi-circular ring push block 3121 fixedly connected to the output end of the first telescopic rod 3113. T-shaped blocks 31211 are fixedly connected to both sides of the outer surface of the semi-circular ring push block 3121. The T-shaped blocks 31211 in the first pushing member 312 are slidably connected to the first T-shaped groove 3115, and the T-shaped blocks 31211 in the second pushing member 313 are slidably connected to the second T-shaped groove 3116. The output end of the second telescopic rod 3114 is fixedly connected to the semi-circular ring push block 3121 in the second pushing member 313. The first telescopic rod 3113 is used to push the semi-circular ring push block 3121 to slide along the first T-shaped groove 3115. The movement of the semi-circular ring push block 3121 is used to finely adjust one side of the first pipe body 1.

[0032] The working principle and usage instructions of the present utility model are as follows: When it is necessary to connect the first pipe body 1 and the second pipe body 2, first, the staff needs to place the ring block 21 in the second pipe body 2 inside the ring groove 11 of the first pipe body 1, and align the clamping block 212 with the clamping groove 112. When there is an offset between the clamping block 212 and the clamping groove 112, resulting in the through groove 113 being unable to align with the threaded groove 213, the staff respectively sleeved and fixed the first auxiliary component 31 and the second auxiliary component 32 at the connection of the first pipe body 1 and the second pipe body 2. At this time, the first pushing member 312 faces the side of the first pipe body 1, and the second pushing member 313 faces the same side of the second pipe body 2. When there is a protrusion on the clamping block 212 in the second pipe body 2, the staff controls the second telescopic rod 3114 to push the second pushing member 313 to slide along the second T-shaped groove 3116. At this time, the second pushing member 313 will push the clamping block 212 in the second pipe body 2 to slide along the clamping groove 112 until the clamping block 212 and the clamping groove 112 are completely and tightly fitted. At this time, the connection between the first pipe body 1 and the second pipe body 2 can be made flat. Then, an external threaded bolt can be passed through the inside of the through groove 113 and threadedly fixed to the threaded groove 213. At this time, the connection work between the first pipe body 1 and the second pipe body 2 can be completed.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
