Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to fig. 1 to 3, and it is obvious that the described embodiments are a part of the embodiments of the present invention, but not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 1 to 3, the novel quick connecting device for pipe fitting butt joint of the present invention comprises a butt joint pipe body 7, wherein two ends of the butt joint pipe body 7 are respectively provided with a nut 1 screwed and fastened with the butt joint pipe body;
the inner wall of the nut 1 is respectively provided with a conical inclined surface part 15, the conical bottom of the conical inclined surface part 15 faces the direction of the butt joint pipe body 7, and the conical top of the conical inclined surface part 15 is far away from the direction of the butt joint pipe body 7;

the inner wall of the nut 1 is provided with a fixed snap ring 2 which is matched and attached with the nut, and one side of the fixed snap ring 2 is provided with a notch 16 which runs through the nut in the axial direction.
Example two
The same parts of this embodiment as those of the first embodiment will not be described again;
referring to fig. 1 to 3, a plurality of convex clamping rings 14 are arranged on the inner wall of the fixing snap ring 2 in the utility model. This structure can be fixed with the outer wall laminating of pipe fitting, does benefit to the centre gripping firmly.
In order to improve the grip on the pipe elements, the protruding ends of the clamping ring 14 are sharp and inclined towards the butt pipe body 7.
In order to facilitate positioning, a skirt 13 is arranged at one end, away from the butt joint pipe body 7, of the pipe fitting positioning ring 3, and the skirt 13 is matched with the end of the butt joint pipe body 7.
In order to facilitate correction and prevent axial deviation, a correction piece 4 is arranged at the joint of the outer wall of the pipe fitting positioning ring 3 and the inner wall of the butt joint pipe body 7.
In order to adapt to pipes with different diameters, the inner diameter of the pipe positioning ring 3 is provided with a plurality of ribs 10.
In order to position the end of the pipe fitting, a baffle ring 6 extending towards the center of the circle is arranged at the middle inner diameter of the butt joint pipe body 7.
In order to improve the overall firmness, a reinforcing rib 12 is arranged at the outer diameter of the butt joint pipe body 7.
The working principle is as follows:
insert two pipe fitting ends respectively in the both ends of butt joint pipe body, when screwing up the nut, the nut utilizes the internal thread 8 to connect the fastening with the mutual screw joint of external screw thread 9 at butt joint pipe body both ends, and the nut can utilize the toper inclined plane portion of inner wall to come the oppression fixed snap ring, and the breach that is equipped with on the fixed snap ring can be compressed for the diameter of fixed snap ring constantly reduces, and then utilizes the clamp ring of fixed snap ring inner wall department to fix the outer wall of pipe fitting, prevents that the axial is not hard up. The pipe fitting locating ring is used for preventing the pipe fitting from shaking laterally, and ribs on the inner wall of the pipe fitting locating ring are used for adapting to fixing pipe fittings with different diameters. After the pipe fitting is fixed, the end head pushes against the baffle ring at the center of the shell for limiting. The rear part of the pipe fitting is axially fixed under the clamping and fixing action of the fixing snap ring. And the left and right fixing is realized through the pipe fitting positioning ring, so that the pipe fitting is finally firmly fixed and cannot be separated. The clamping of different diameter pipe fittings is realized through the range of deformation of fixed snap ring, and then realizes the butt joint UNICOM of different diameter pipe fittings. The correction sheet can further improve the positioning in the lateral direction.
When the pipe fitting is disassembled, the pipe fitting can be directly pulled out without completely disassembling the pipe fitting and only slightly loosening the screw cap to lose the clamping force for fixing the clamping ring, and the pipe fitting can be directly inserted after next use, so that the use is convenient and fast.
The butt joint pipe fitting is simple and practical in structure, the ends of the two pipe fittings are inserted into the butt joint pipe body, the clamping force is adjusted through the tightness of the nuts, and the pipe fittings can be fixed in the axial direction. The pipe fitting holding ring can carry out the centre gripping of side direction to the pipe fitting, and the rib can adapt to the pipe fitting of different diameters, realizes the fixed of side direction. When the installation is dismantled, need not all to unpack apart the accessory, only need not hard up the nut, force fixed snap ring not hard up, can realize the insertion and the extraction of pipe fitting, convenient to use. The clamping ring for fixing the inner wall of the clamping ring can firmly fix the pipe fitting, and the pipe fitting is prevented from being separated from the pipe fitting due to overlarge water pressure.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
