Drawings
Embodiments of the present invention are described below with reference to the accompanying drawings, in which:
fig. 1 is a side sectional view of a pipe cap with a coupling nut according to the present invention.
Detailed Description
The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
Referring to fig. 1, the pipe cap with a coupling nut of the present invention includes a threaded connection portion 10, a cap body 20, and a sealing ring 30.
The cap body 20 is connected to the threaded connection portion 10, and the seal ring 30 is located between the threaded connection portion 10 and the cap body 20.
An extension groove 21 is axially formed in the middle of one end of the cap body 20. The cap body 20 is provided with a stopper ring 22 protruding radially outward outside the opening of the extension groove 21.
Connecting hole 11 has been seted up along the axial in the middle part of threaded connection portion 10, and the middle part of the inside wall of connecting hole 11 is sunken to be provided with connecting groove 12, and the axial degree of depth of connecting groove 12 along threaded connection portion 10 is greater than the height of spacing ring 22. A stop collar 22 is located in the attachment slot 12. This allows the threaded connection 10 to be rotated relative to the cap 20.
The inner side wall of the connecting hole 11 of the threaded connecting part 10 is provided with an internal thread for being in threaded connection with an external thread of an external water pipe. The screw connection 10 is rotated to be screwed or unscrewed with an external water pipe. In other embodiments, the outer side wall of the threaded connection portion 10 may also be provided with an external thread to connect with an internal thread of an external water pipe.
An annular caulking groove 121 is concavely arranged on one side of the connecting groove 12 of the threaded connecting part 10 close to the middle part of the cap body 20, and the sealing ring 30 is embedded in the caulking groove 121. The section of the caulking groove 121 is arc-shaped, and the opening angle of the section is larger than 180 degrees.
When the external water pipe is connected to the threaded connection portion 10, the threaded connection portion 10 moves in a direction away from the middle of the cap body 20, so that the sealing ring 30 is extruded and deformed, thereby achieving sealing.
The diameter of the connection hole 11 is slightly larger than that of the extension groove 21, and when an external water pipe is connected to the screw connection part 10, the diameter of the water pipe is the same as or equivalent to that of the connection hole 11.
Compared with the prior art, the pipe cap with the connecting nut of the utility model comprises a threaded connection part 10, a cap body 20 connected with the threaded connection part 10 and a sealing ring 30 arranged between the threaded connection part 10 and the cap body 20; an extension groove 21 is axially arranged in the middle of one end of the cap body 20; the cap body 20 is provided with a limiting ring 22 which protrudes outwards along the radial direction at the outer side of the opening of the extension groove 21; connecting hole 11 has been seted up along the axial in the middle part of threaded connection portion 10, and the middle part of the inside wall of connecting hole 11 is sunken to be provided with connecting groove 12, and the degree of depth of connecting groove 12 is greater than the height of spacing ring 22, and spacing ring 22 is arranged in connecting groove 12. Through threaded connection portion and outside water pipe threaded connection, realize sealed through the sealing washer, so easy to assemble and dismantle.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
