The protection architecture of a metal joint, its characterized in that: the tool withdrawal groove is of a ring groove structure.
The protection architecture of a metal joint, its characterized in that: the inner diameter of the tool withdrawal groove is larger than that of the inner thread end of the protective sleeve body.
The protection architecture of a metal joint, its characterized in that: the internal diameter of the sleeve opening is smaller than that of the internal thread end of the protective sleeve body.
The protection architecture of a metal joint, its characterized in that: the metal joint is characterized in that an external thread end is arranged at the end part of the metal joint and is used for being matched with an internal thread end, the tool withdrawal groove is used for enabling the external thread end to continuously advance to the sleeve opening, and the end face of the metal joint can be attached to the inner wall face of the sleeve opening.
The protection architecture of a metal joint, its characterized in that: the metal joint comprises a metal joint outer sleeve and a metal joint inner core.
The protection architecture of a metal joint, its characterized in that: the composite pipe is arranged between the metal joint outer sleeve and the metal joint inner core, first inner teeth are arranged at the matching position of the metal joint outer sleeve and the composite pipe, and second inner teeth are arranged at the matching position of the metal joint inner core and the composite pipe.
Compared with the prior art, the beneficial effects of the utility model are that:
1) by adopting the technical scheme of the utility model, through setting the tool withdrawal groove, on one hand, the processing is convenient, because the hollow groove structure is designed in the protective sleeve, the thread of the protective sleeve can be continuously screwed inwards, so that the end part of the metal joint and the inner wall of the sleeve opening are tightly attached, on the other hand, even if the pressure deformation is received subsequently, the stress is most obvious because of the position of the metal joint port, a certain deformation space can be provided through the arranged hollow groove structure, and meanwhile, the end surface is attached, so that the stress is relatively more uniform;
2) the utility model has the characteristics of simple structure, practicality are strong, with low costs and spreading value is high.
