[0019] Example

[0020] See also Figure 1-5 The utility model discloses a pipeline connector which is easy to install: it comprises a first connector 1, a second connector 2, a fixing mechanism 3 and a sealing mechanism 4. The second connector 2 is arranged on one side of the first connector 1, and the fixing mechanism 3 is arranged on the inner sides of the first connector 1 and the second connector 2. The fixing mechanism 3 comprises a threaded hole 301, a plug hole 302, a threaded rod 303, a limit plate 304 and a nut 307. A threaded hole 301 is penetrated on one side of the first connector 1, and a plug hole 302 is penetrated on one side of the second connector 2. A threaded rod 303 is threadedly connected to the inner side of the threaded hole 301, one end of the threaded rod 303 is fixedly connected to the limit plate 304, and a nut 307 is threadedly connected to the outer side of the threaded rod 303. A sealing mechanism 4 is arranged between the first connector 1 and the second connector 2. When the pipelines are docked, , the first connecting member 1 and the second connecting member 2 are welded to the two pipes respectively, and then the threaded rod 303 is threadedly connected to the threaded hole 301 so that the limit plate 304 fits with the first connecting member 1, and then the threaded rod 303 is inserted into the socket 302 on the second connecting member 2, and then the slide plate 305 is put on the threaded rod 303, the slide plate 305 is slidably connected to the threaded rod 303, and then the threaded rod 303 is threadedly connected with the nut 307, and the slide plate 305 is pushed so that the spring 306 contacts one side of the second connecting member 2, and the nut 307 is tightened to compress the spring 306, and then the pin 309 is inserted into the socket 302, and the resilience of the spring 306 can make the fit between the first connecting member 1 and the second connecting member 2 tighter, so as to ensure the stable connection between the first connecting member 1 and the second connecting member 2.

[0021] In order to facilitate the connection between the first connecting member 1 and the second connecting member 2, the threaded rod 303 slides through the socket 302 and fits therewith. Four fixing mechanisms 3 are provided. Through the provision of the fixing mechanisms 3, the first connecting member 1 and the second connecting member 2 can be better connected to ensure the stability of the connection.

[0022] In order to facilitate the connection between the first connecting member 1 and the second connecting member 2, the fixing mechanism 3 also includes a slide plate 305, a spring 306, a through hole 308 and a pin 309. The slide plate 305 is sleeved on the outer side of the threaded rod 303, and the spring 306 is fixedly connected to one side of the slide plate 305. A through hole 308 is opened on the outer side of the threaded rod 303, and the pin 309 is inserted into the inner side of the through hole 308. Through the arrangement of the slide plate 305 and the spring 306, the second connecting member 2 can be pushed to ensure a stable connection.

[0023] In order to facilitate pushing the second connecting member 2 , the spring 306 is sleeved on the outer side of the threaded rod 303 .

[0024] In order to ensure the sealing of the connection, the sealing mechanism 4 includes a first sealing gasket 401, a second sealing gasket 402, a clamp 403 and an inclined surface 404. The first sealing gasket 401 is arranged on one side of the first connecting member 1, and the second sealing gasket 402 is arranged on one side of the second connecting member 2. The first sealing gasket 401 includes a clamp 403 and an inclined surface 404. Through the setting of the inclined surface 404, when water flows through, the resistance to the water flow can be reduced, thereby playing a guiding effect. When the first connecting member 1 and the second connecting member 2 are fixed, the first sealing gasket 401 and the second sealing gasket 402 will be clamped to ensure sealing.

[0025] In order to ensure the sealing of the connection, the first sealing gasket 401 and the second sealing gasket 402 are matched in size.

[0026] Working principle: When the pipes are connected, the first connector 1 and the second connector 2 are welded to the two pipes respectively, and then the threaded rod 303 is threadedly connected to the threaded hole 301, so that the limit plate 304 fits with the first connector 1, and then the threaded rod 303 is inserted into the socket 302 on the second connector 2, and then the slide plate 305 is put on the threaded rod 303, and the slide plate 305 is slidably connected to the threaded rod 303, and then the nut 307 is threadedly connected to the threaded rod 303, and the slide plate 305 is pushed so that the spring 306 contacts the second connector 2. On the other hand, tightening the nut 307 will compress the spring 306, and then insert the pin 309 into the socket 302. The resilience of the spring 306 can make the first connector 1 and the second connector 2 fit more tightly, thereby ensuring a stable connection between the first connector 1 and the second connector 2. By setting the inclined surface 404, the resistance to the water flow can be reduced when water flows through, thereby achieving a diversion effect. When the first connector 1 and the second connector 2 are fixed, the first sealing gasket 401 and the second sealing gasket 402 will be clamped to ensure sealing.
