[0021] See also Figure 1-Figure 2 The utility model provides a technical solution: a sealing structure, including a connector 1, which is fixed at the pipe mouth of a four-way body 2. The pipe mouth of the connector 1 is used for threaded connection with a conveying pipe body. A rubber cover 5 is embedded at one end of the connector 1 away from the four-way body 2. After the rubber cover 5 is pulled out and inserted into the pipe mouth of the connector 1, it is clamped at the threaded connection between the conveying pipe and the connector 1 to strengthen the connection firmness between the connector 1 and the conveying pipe body.

[0022] Embodiment 2

[0023] Refer to the attached Figure 3 As shown, on the basis of Example 1, in order to realize the threaded connection between the conveying tube body and the connecting head 1, the connecting head 1 is a ring structure with an inner ring opening as a "convex"-shaped circular opening. The inner ring diameter of one end of the connecting head 1 connected to the four-way body 2 is equal to the pipe opening diameter of the four-way body 2, and the outer diameter of the connecting head 1 is larger than the outer diameter of the four-way body 2; the inner ring opening of the end of the connecting head 1 away from the four-way body 2 is provided with an internal thread groove 3 for cooperating with the external thread provided on the outer wall of the conveying tube body, the internal thread groove 3 and the external thread are matched and connected, and then the connecting head 1 and the conveying tube body are threadedly connected.

[0024] The conveying pipe body is screwed on the connectors 1 at the four ends of the four-way body 2 to achieve the flow diversion effect of the four-way body 2, and the conveying pipe body and the connectors 1 are screwed, which is convenient for quick installation and removal of the conveying pipe body.

[0025] Embodiment 3

[0026] Refer to the attached Figure 4 As shown, on the basis of Example 2, in order to achieve sealing after the conveying pipe body and the connecting head 1 are screwed together, an embedding groove 4 is opened at the end of the connecting head 1 away from the four-way body 2, and the embedding groove 4 is an annular groove. A rubber cover 5 is fixed inside the embedding groove 4, and the tube length of the rubber cover 5 is less than the length of the internal thread groove 3; the rubber cover 5 is pulled out of the embedding groove 4, folded over and inserted into the pipe mouth of the connecting head 1, and the rubber cover 5 is clamped between the conveying pipe body and the connecting head 1 to reinforce the firmness of the screw connection; a rubber retaining ring 6 is fixed on the outer ring surface of the embedding groove 4, and the inner ring diameter of the rubber retaining ring 6 is equal to the inner ring diameter of the embedding groove 4.
