FIG. 1 is a schematic structural view of a preferred embodiment of the present invention;
fig. 2 is a sectional view of the preferred embodiment of the present invention.
Wherein, in the figures, the respective reference numerals:
10. a butt joint section; 101. a limiting bulge; 20. a nut; 201. an abutting portion; 30. a receiving section; 301. a guide slope; 302. the boss is rotated.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
The utility model discloses referring to fig. 1-2 and showing, including the butt joint section 10 and the nut 20 that the shape is the cavity pipe, nut 20 suit in the butt joint section 10 outside just can round the rotation axis of butt joint section 10 rotates. When the scheme is used, the butt joint section 10 of the pipe fitting loose joint can be aligned with other pipe sections, then the nut 20 is moved to the joint of the butt joint section 10 and the other pipe sections, and finally the nut 20 is rotated to be connected and matched with the external threads of the other pipe sections, so that the connection between one pipe fitting and the loose joint is completed. Through the arrangement, the nut 20 is sleeved on the butt joint section 10, so that the separation of the two or the waste of time caused by searching the matched nut 20 can be avoided, and meanwhile, the mode of connecting the nut 20 is adopted to be more compact and the operation is simple and convenient, so that the purpose of improving the working efficiency is achieved.
As a preferred embodiment of the present invention, it may also have the following additional technical features:
in this embodiment, referring to fig. 2, the butt joint section 10 is provided with a limiting protrusion 101, and the nut 20 is provided with an abutting portion 201 abutting against the limiting protrusion 101. Through the cooperation setting of spacing arch 101 and butt joint portion 201, can prevent that nut 20 from slipping from butt joint section 10, when nut 20 screws up simultaneously, whether can confirm nut 20 through the cooperation of spacing arch 101 and butt joint portion 201 and screw up completely, improve the compactness of being connected between pipeline section and the union.
In combination with the arrangement of the limiting protrusion 101 and the abutting portion 201, in this embodiment, a sealing member is disposed on the surface of the limiting protrusion 101 opposite to the abutting portion 201. When the nut 20 is screwed to the limit position, the limit protrusion 101 and the abutting part 201 are in fit abutment, and at the moment, the gap between the nut 20 and the butt joint section 10 can be closed through the arrangement of the sealing element, so that fluid is prevented from flowing out of the gap to influence the connection effect. The sealing element in this embodiment is a sealing rubber ring, and in other embodiments, the sealing element may also be a sealing adhesive tape and directly wound around the joint between the nut 20 and the butt section 10.
In this embodiment, referring to fig. 1-2, the pipe fitting further includes a receiving section 30 disposed at one end of the butt-joint section 10, and the receiving section 30 is a hollow pipe fitting and has a diameter larger than that of the butt-joint section 10. Through the arrangement of the bearing section 30, the middle through hole of the bearing section 30 can be connected and fixed with another pipe section in a socket welding mode, so that the two pipe sections are fixedly connected with the movable joint. Meanwhile, the diameter of the receiving section 30 is larger, so that another pipe section can conveniently extend into the receiving section, a certain limiting effect is achieved on the other pipe end (the other pipe section can be judged to be in place when extending into and abutting against the butt-joint section 10), and finally, the receiving section is fixed, so that the connecting sealing effect is better.
In combination with the arrangement of the receiving section 30, in the embodiment, referring to fig. 2, a guiding inclined plane 301 is disposed at a connection position of the receiving section 30 and the connecting section 10. Through the arrangement of the guide inclined plane 301, when the fluid flows from the bearing section 30 to the butt joint section 10, the transition can be more smooth and not blocked.
In combination with the arrangement of the receiving section 30, in this embodiment, the inner wall of the receiving section 30 is provided with a thread. Through the setting of internal thread, accept section 30 the same accessible threaded connection's mode and realize being connected fixedly with other pipeline sections, the connected mode is more various, easy operation, and compactness is also better simultaneously.
In combination with the arrangement of the internal threads, referring to fig. 1-2, in this embodiment, a rotating protrusion 302 for a human hand to rotate is disposed on an outer wall of the receiving section 30. Wherein the screw-thread fit makes the installation of accepting section 30 dismantle all need realize through the pivoted mode, consequently through the setting of above-mentioned rotation arch 302 for the user can carry out the application of force and then more convenient drive to accept section 30 and rotate to rotation arch 302. In this embodiment, the rotating protrusion 302 is a hexagonal protrusion similar to the nut 20, so that when the receiving section 30 rotates to any angle, the user can have a force application point to drive the receiving section 30 to rotate. In other embodiments, the structure of the rotating protrusion 302 may also be two opposite bar-shaped protrusions, and is not limited to the above implementation.
The above additional technical features can be freely combined and used in superposition by those skilled in the art without conflict.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
