DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present utility model will be further described below with reference to the drawings and embodiments.

[0021] Please refer to Figure 1 and Figure 2 , wherein Figure 1 is a schematic structural diagram of a preferred embodiment of a connection structure provided by the present utility model; Figure 2 is Figure 1 an enlarged schematic view of part A shown in. A connection structure includes:

[0022] A rectangular frame 1, with pipelines 2 arranged on both the left and right sides of the rectangular frame 1;

[0023] A splicing component 3, which is arranged between the rectangular frame 1 and the pipeline 2;

[0024] A fixing component 4, which is arranged between the pipeline 2 and the rectangular frame 1.

[0025] The splicing component 3 includes a splicing groove 31, and a splicing frame 32 is arranged inside the splicing groove 31.

[0026] A sealing gasket 33 is adhesively bonded to the inner wall of the splicing groove 31.

[0027] The splicing groove 31 is opened on the side of the rectangular frame 1. One end of the splicing frame 32 is connected to the end of the pipeline 2. The use of the sealing gasket 33 can improve the sealing performance of the connection between the pipeline 2 and the rectangular frame 1.
