Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiment of the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Embodiments of the present invention will be described in further detail below with reference to the following drawings, in which:
a novel structure of preventing tearing open for refrigerating system, including stop valve body 1, stop valve body 1 has slotted nut 2 through threaded connection to lie in and wear to be equipped with variable dog 3 between stop valve body 1 and the slotted nut 2, slotted nut 2 is hollow structure, and its inner wall corresponds the one end of variable dog 3 around having seted up spread groove 4, and variable dog 3 adopts the dull and stereotyped stamping forming of stainless steel annular, and is the toper column structure after its shaping, and lies in the punching press and fall angle department and adopt the circular arc transition.
The slotted nut 2 is formed by lathing a hexagonal rod or a forged blank, an internal thread is arranged on the slotted nut 2 corresponding to the external thread, and a tool withdrawal groove 6 is arranged at the tail end of the internal thread.
The utility model discloses a prevent tearing open structure comprises two main part: a slotted nut 2 and a variable stop 3; the slotted nut 2 is turned by a hexagonal rod (or a forging blank), the internal thread of the slotted nut is matched with the external thread of the stop valve body 1, the thread tail end is provided with a tool withdrawal groove 6, the variable stop block 3 is formed by punching and forming a stainless steel annular flat plate, the variable stop block is conical after being formed, the arc transition of a stamping collapsed angle is realized, the thread is not damaged when the stop valve body 1 (or a pipe joint) is installed, the variable stop block 3 is matched with the slotted nut 2, the conical variable stop block 3 is pressed under the thrust of the slotted nut 2, the connecting groove 4 of the slotted nut 2 is flattened, the slotted nut 2 is fastened, and the anti-dismantling function.
Taking the working principle combined with the structure as an example:
the first embodiment is as follows: the stop valve body 1 is matched with the slotted nut 2 to press the variable stop block 3 into the connecting groove 4 and to be in an unfolded state; after stop valve body 1 is packed into to variable dog 3 that is the toper structure, exert the locking force to slotted nut 2 through outer hexagonal, slotted nut 2's internal thread and stop valve body 1 external screw thread connection, behind locking slotted nut 2, variable dog 3 is under slotted nut 2's thrust, impress in slotted nut 2's the spread groove 4 and expand, 3 internal diameters of variable dog after the exhibition is flat are far less than stop valve body 1's external screw thread big footpath, make to apply reverse torsion to slotted nut 2 outer hexagonal and try to twist out slotted nut 2 when obstructed, thereby realize preventing tearing open the function.
