Moreover, the protective cover 14 can protect the threaded hole 1111 and the clasping member 112, and prevent external dust and other dirt from falling into the threaded hole 1111 or the clasping member 112, so as to avoid influencing the adaptation between the clasping member 112 and the threaded hole 1111. Meanwhile, under the condition that the clasping member 112 is made of metal, liquid can be prevented from dripping and remaining on the clasping member 112, so that the probability that the clasping member 112 is corroded is reduced, and the situation that the clasping member 112 cannot be disassembled and assembled due to too serious corrosion is prevented from occurring.

It should be noted that, in the present application, the structure of the housing 111 and the first sealing member 13 may adopt any one of the following embodiments:

example 1: referring to fig. 3 and 5, the radial length of the first sealing end surface 131 is greater than the radial length of the second sealing end surface 132, the housing 111 includes a first housing 1112 provided with a threaded hole 1111 and a second housing 1113 fixedly connected to the first housing 1112, the inner diameter of the first housing 1112 is greater than the inner diameter of the second housing 1113, and the inner diameter of the second housing 1113 is smaller than the radial length of the first sealing end surface 131.

Preferably, the radial length of the second seal end face 132 of the first seal 13 is commensurate with the inner diameter of the second housing 1113 such that the sides of the first seal 13 and the inner side wall of the second housing 1113 form a seal.

It can be understood by those skilled in the art that, with the structure described in this embodiment, on one hand, the outer shape of the first sealing member 13 is matched with the inner shape of the housing 111, that is, when the first sealing member 13 is placed in the housing 111, the first sealing end surface 131 with the larger inner diameter of the first sealing member 13 can be supported by the second housing 1113 with the smaller inner diameter, so that the housing 111 and the first sealing member 13 can be installed to a pipeline as one assembly, which improves the assembly efficiency, and when the assembly is performed, the second housing 1113 with the smaller inner diameter can abut against the end surface of the pipeline, so as to avoid the first sealing member 13 being squeezed off or deformed greatly to affect the sealing effect; on the other hand, the inner diameter of the first housing 1112 can be made as large as possible to match pipelines with various calibers, and meanwhile, the inner diameter of the second housing 1113 does not need to be changed, so that the pipeline joint can be adapted to pipelines with more sizes, connection with a universal adapter and a faucet auxiliary device is guaranteed, and the application range is expanded.

Example 2: referring to fig. 7 to 9, the radial length of the first sealing end surface 131 is smaller than the radial length of the second sealing end surface 132, the housing 111 includes a first housing 1112 provided with a threaded hole 1111 and a second housing 1113 fixedly connected to the first housing 1112, the inner diameter of the first housing 1112 is smaller than the inner diameter of the second housing 1113, and the inner diameter of the first housing 1112 is smaller than the radial length of the second sealing end surface 132.

Therefore, when the pipeline joint of the present embodiment is assembled with the pipeline, the housing 111 and the pipeline need to be fixed in place, and then the adaptor 12 is assembled with the housing 111 against the first sealing member 13. Preferably, the radial length of the first seal end face 131 of the first seal 13 is commensurate with the inner diameter of the first housing 1112 such that the sides of the first seal 13 form a seal with the inner side wall of the first housing 1112.
