Description of the embodiments
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will be further described in detail below with reference to the accompanying drawings and examples of the present utility model. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
On the contrary, the utility model is intended to cover any alternatives, modifications, equivalents, and variations as may be included within the spirit and scope of the utility model as defined by the appended claims. Further, in the following detailed description of the present utility model, certain specific details are set forth in order to provide a better understanding of the present utility model. The present utility model will be fully understood by those skilled in the art without the details described herein.
Referring to fig. 1 to 5, a high-strength water-leakage-proof pipe connection structure comprises a male screw insert 1, a male screw joint pipe fitting plastic body 2, a female screw insert 4, a female screw joint pipe fitting plastic body 3 and a thermal welding plastic body gasket 5; the male threaded insert 1, the female threaded insert 4 and the thermowelded plastic gasket 5 are combined to form a connecting assembly for connecting the male fitting plastic 2 and the female fitting plastic 3.
Specifically, the male threaded insert 1 is a cylindrical hollow structure, an external thread section is arranged on the outer side of the upper portion of the male threaded insert, an annular boss is arranged on the outer side of the lower portion of the male threaded insert, the lower portion of the male threaded insert is embedded and fixed in the male threaded joint pipe fitting plastic body 2 by adopting a cladding injection method, and the male threaded insert 1 and the male threaded joint pipe fitting plastic body 2 are coaxially arranged.
