Further, the coupling chamber wall of boss top is the notch cuttype and reduces gradually from last to diameter down, all forms the flank on the chamber wall of each ladder end, first connecting sleeve is located the intracavity of coupling and threaded connection at the little ladder section department of internal diameter. The stepped configuration of the wall of the pipe joint cavity is convenient for butt joint with external pipelines and the like.
Furthermore, the end part of the universal pipe is embedded and fixed in the cavity of the second connecting sleeve, so that the universal pipe is convenient to assemble and mold.
Furthermore, the first connecting sleeve and the second connecting sleeve are both cylindrical.
Furthermore, a sealing ring is arranged between the tail end of the first connecting sleeve and the boss below the first connecting sleeve, so that the sealing performance is further improved by the sealing ring.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses improve universal pipe fastening structure, help improving the leakproofness, convenient equipment shaping.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.
FIG. 1 is a schematic sectional view showing a structure of a joint pipe fastening structure according to embodiment 1;
wherein the reference numerals are:
1. an inner tube; 2. an outer tube; 3. a pipe joint; 4. fastening the inner core; 5. a first connecting sleeve; 6. a second connecting sleeve; 7. a seal ring; 8. and (4) a boss.
Detailed Description
The invention will be further explained with reference to the drawings and the specific embodiments.
Example 1
As shown in fig. 1, the universal pipe fastening structure in this embodiment includes a universal pipe, a pipe joint, and a fastening inner core, wherein the universal pipe is formed by using a common inner pipe 1 and an outer pipe 2, the inner pipe 1 is formed by an elastic material, the outer pipe 2 is formed by a metal material, the pipe joint 3 is formed by using a cylindrical configuration, the fastening inner core 4 is formed by using a common T-shape and is formed with a cavity along a shaft center line, and the universal pipe, the pipe joint, and the fastening inner core are common structures, which are not described again.
In this example, a cylindrical first connecting sleeve 5 and a cylindrical second connecting sleeve 6 are added, and an annular boss 8 is formed on the cavity wall of the middle position of the pipe joint 3 in a radially outward protruding mode along the circumferential direction. The peripheral wall of the first connecting sleeve 5 is provided with a formed threaded surface, the first connecting sleeve 5 is in threaded connection with the cavity of the pipe joint 3 above the boss 8, and the second connecting sleeve 6 is in a step shape, and the head end part with the small shaft diameter is embedded into the annular opening of the boss 8. The tip embedding second adapter sleeve 6 of universal pipe intracavity, the outer tube 2 of universal pipe and the chamber wall interference fit of second adapter sleeve 6 promptly, the inner tube 1 of universal pipe stretches out and stretches into 5 intracavitys of first adapter sleeve from the tip, and the intracavity of inner tube 1 is stretched into through the mode of punching press to the longitudinal end of fastening inner core 4, and the chamber wall centre gripping of fastening inner core 4 and first adapter sleeve 5 is fixed to the 1 pipe wall centre gripping of inner tube between the two. Under this structure, the punching press process reduces convenient equipment, even the fastening inner core appears damaged with the inner tube junction, the fixed knot of universal pipe outer tube and second adapter sleeve constructs to help reducing the phenomenon of leaking.
When the sealing device is used, in order to improve the sealing property, a sealing ring 7 can be additionally arranged between the bottom of the first connecting sleeve 5 and the boss 8, and the sealing ring is beneficial to sealing off a water leakage and leakage channel at the threaded butt joint part of the first connecting sleeve and the joint part of the fastening inner core and the hose.
In order to facilitate the butt joint of external pipelines and the like, the wall of the pipe joint 3 above the boss is in a two-stage step type in the embodiment, thread surfaces are formed on two step sections, the inner diameter of the step section at the pipe orifice is large so as to facilitate the threaded connection with an external pipeline, the first connecting sleeve 5 is in threaded connection with the step section with a small inner diameter below the pipe orifice, and the thread surfaces can be formed on the outer peripheral wall of the pipe orifice to facilitate the butt joint.
Above only the utility model discloses an it is preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
