[0033] See also Figure 3 , 4 As shown:

[0034] The utility model pipe installation assembly comprises: a soft pipe 5 and a hard pipe 6, and a pipe connecting component, through which two adjacent soft pipes 5 are transitionally connected and the soft pipe 5 and the hard pipe 6 are transitionally connected;

[0035] The pipe connecting component includes a core pipe, which has a core pipe body 1 and a connecting column 101 fixedly connected to the core pipe body 1. The core pipe body 1 is plug-in connected to the soft pipe 5 through the connecting column 101 and is threadedly connected to the hard pipe 6 through the connecting column 101. A faucet is fixedly connected to the end of the hard pipe 6.

[0036] When in use, when the two ends of the core tube body 1 are transitionally connected to two adjacent soft pipes 5, the core tube body 1 is connected to the soft pipe 5 in the form of a plug-in connection through the connecting column 101, and the outer wall of the soft pipe 5 can be deformed by the screw sleeve 2 and the locking plate 103 to make the plug-in cavity 102 shrink and tightly embrace the plugged soft pipe 5, or the connecting column 101 is exposed to the outside and the soft pipe 5 is locked by the stainless steel throat clamp in the prior art.

[0037] When one end of the core tube body 1 is plug-connected to the soft tube 5 through the connecting column 101, and the other end is threadedly connected to the hard tube 6 through the connecting column 101, a faucet is installed at the end of the hard tube 6, and a protrusion is formed on the outside of the hard tube 6. The side wall of the protrusion forms a limited position surface 601. The limited position surface 601 is in sealing contact with the end surface of the connecting column 101, thereby realizing the transition connection of two pipes of different materials. A faucet is fixedly connected to the end of the hard tube 6, and the water flow is closed in time through the faucet. Of course, the faucet can also be a valve that can be manually closed in the prior art.
