Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
The terms "first" and "second" in this specification do not denote a particular quantity or order, but rather are used for distinguishing between similar or identical items.

When the pipe 10 abuts against the first clamping position 112, water can be effectively prevented from flowing out of the gap between the pipe 10 and the transparent inner core 110 due to the sealing effect of the pipe 10 and the first clamping position 112, so that leakage is avoided.
The protective layer 120 serves to prevent external light from entering the mounting hole 111. In the piping system, when sunlight irradiates the piping and light irradiates the water, a small amount of algae and microorganisms in the water will generate light to be used as propagation and growth, which can eventually lead to water pollution, and by covering the transparent inner core 110 with a protective layer 120, external light can be effectively prevented from entering the mounting hole 111, and light is prevented from irradiating the water in the piping, thereby preventing water from being polluted.
Optionally, the protective layer 120 is an opaque plastic layer or a metal layer. Specifically, the protective layer 120 is an opaque plastic layer, the pipe body 100 is manufactured by a two-shot molding process, the transparent inner core 110 inside the pipe body is molded by using a transparent material, and the protective layer 120 is manufactured by the second shot molding process.

In this way, the first outer shell 200 is coupled to the pipe body 100 to facilitate installation of the outer seal connection pipe.
In the external sealing connection pipe fitting described above, since the transparent inner core 110 is made of transparent or semitransparent material, it does not obstruct the installer from viewing the structure in the installation hole 111 through the first observation hole 210, so, when the pipe 10 is inserted into the pipe fitting body 100, the installer can intuitively see whether the pipe 10 has been inserted into the clamping position through the first observation hole 210 on the first outer shell 200, thereby effectively reducing the risk of leakage caused by the pipe 10 not being inserted in place. And because the transparent inner core 110 is sleeved on the pipe 10, the pipe 10 can be prevented from being directly contacted with the external environment and being polluted by the external environment. And through covering a layer of protection 120 layer on transparent inner core 110, can prevent effectively that external illumination from getting into mounting hole 111, prevent that light from shining the water in the pipeline to avoid the quality of water to be polluted.
As shown in fig. 2-3, further, the first outer shell 200 is rotatably sleeved on the pipe body 100, the protective layer 120 is provided with a first perspective hole 121, the first outer shell 200 includes a first installation position and a second installation position, when the first outer shell 200 is in the first installation position, the first observation hole 210 is opposite to the first perspective hole 121, and when the first outer shell 200 is in the second installation position, the first observation hole 210 is staggered with the first perspective hole 121.

Thus, when the pipe 10 is pushed against the teeth 410 and inserted into the pipe body 100, the teeth 410 deform and tightly press against the pipe 10, so as to prevent the pipe 10 from slipping.
Further, the external sealing connection pipe fitting further includes a gasket 500, the gasket 500 is disposed in the mounting hole 111 or the inner hole 220 and is located at one side of the snap ring 400 near the first clamping position 112, the gasket 500 includes a first opening 510 and a second opening 520 opposite to the first opening 510, the first opening 510 is opposite to the snap ring 400, and the diameter of the inner ring of the gasket 500 is in a decreasing trend along the direction from the first opening 510 to the second opening 520. Thus, when the pipe 10 is inserted into the pipe body 100, the teeth 410 are in abutting fit with the inner wall of the gasket 500, and the inner wall of the gasket 500 can avoid the damage of the teeth 410 or the weakening of elastic force caused by excessive expansion of the teeth 410 in the process of pushing the teeth 410 by the pipe 10, thereby prolonging the service life of the snap ring 400.
In one embodiment, the external sealing connection pipe fitting further includes a pipe taking sleeve 600 penetrating through the first outer shell 200, and an inner cavity of the pipe taking sleeve 600 is communicated with the mounting hole 111, and a pressing surface 610 is disposed at one end of the pipe taking sleeve 600 away from the first clamping position 112.

The second housing 800 is identical to the first housing 200 in structure, and the pipe body 100 has a symmetrical structure. In this manner, both ends of the outer sealing connection tube can be connected to the tube 10 in the same manner.
As shown in fig. 4, it can be seen from the second observation hole 810 that the pipe 10 at the upper end is inserted in place, and from the first observation hole 210 that the pipe 10 at the lower end is not inserted in place, so that an intuitive judgment can be made.
As shown in fig. 5, when the pipe is connected to the outer sealing connection pipe, the first outer shell 200 is rotated so as to close the first observation hole 210, thereby preventing light from entering the inside of the pipe.
