Abstract

Open a kind of anti-loosening 90 degree exterior plug pepe bends of the utility model, comprise top straight tube and bottom straight tube, joint, outer silk head, between the axis of top straight tube and bottom straight tube, form 90 degree angles, a described outer silk free end arranges circular deep gouge, also comprise spring structure, described spring structure has helical spring body and is arranged on the tubular connecting body with external screw thread of described helical spring body one end, and described spring structure is spirally connected by this tubular connecting body and described deep gouge.(1) the utility model outside a silk cephalic par be provided with spring structure, after the silk head of elbow is connected with the silk mouth of taking over, spring structure can be given prestressing force of above-mentioned linkage structure, after linkage structure is spirally connected, contributes to described linkage structure connection more firm; (2) spring structure of the present utility model is connected with a silk mouthful end for elbow by connecting body, and combination and dismounting are all more for convenience.

Description

Anti-loosening 90 degree exterior plug pepe bends
Technical field
The utility model relates to a kind of elbow, relates in particular to a kind of anti-loosening 90 degree exterior plug pepe bends.
Background technique
Elbow is a kind of connecting pipe part (link) conventional in plumbing pipe system installation process, for the connection of pipeline corner, changes the direction of pipeline with this.In engineering practice, we find, can there is the situation of certain vibration in some stringing operating areas, the source of vibration is comparatively various, when the adapter being arranged in above-mentioned zone is while adopting situation about being threaded with joint, elbow silk head (internal thread or outer silk) can be because external force vibration causes becoming flexible of linkage structure with adapter termination silk head (internal thread or outer silk) joint, so long-term, can cause elbow silk head to be connected firm not with an adapter silk linkage structure, sealability declines, and serious also can cause leakage.
Model utility content
The problems referred to above that exist for prior art, the utility model provides a kind of anti-loosening 90 degree exterior plug pepe bends.
To achieve these goals, the utility model adopts following technological scheme: a kind of anti-loosening 90 degree exterior plug pepe bends, comprise: top straight tube and bottom straight tube, joint, outer silk head, between the axis of top straight tube and bottom straight tube, form 90 degree angles, top straight tube and joint transition position have the first annular boss, bottom straight tube and joint transition position have the second annular boss, described connecting tube is curve bend structure, the two ends of connecting tube connect respectively a port of top straight tube and bottom straight tube, described top another port of straight tube is connected with outer silk head, described outer silk head surface is screw thread, described bottom another port of straight tube is connected with the flared type mouth of pipe, the surface of described elbow body is provided with socket joint deep identification and body nominal diameter mark and socket joint direction signs, a described outer silk free end arranges circular deep gouge, also comprise spring structure, described spring structure has helical spring body and is arranged on the tubular connecting body with external screw thread of described helical spring body one end, described spring structure is spirally connected by this tubular connecting body and described deep gouge.
Further, the dead in line of the axis of described spring structure and described outer silk head.
Further, described helical spring body axial length is not more than 2cm.
Compared to existing technology, the utlity model has following advantage: (1) the utility model outside silk cephalic par is provided with spring structure, after the silk head of elbow is connected with the silk mouth of taking over, spring structure can be given prestressing force of above-mentioned linkage structure, after linkage structure is spirally connected, contribute to described linkage structure to connect more firm; (2) spring structure of the present utility model is connected with a silk mouthful end for elbow by connecting body, and combination and dismounting are all more for convenience.
Brief description of the drawings
Fig. 1 is anti-loosening 90 degree exterior plug pepe bend structural representations in embodiment.
Fig. 2 is tubular connecting body structural representation.
Description of reference numerals: 1-top straight tube, 10-the first annular boss, 2-bottom straight tube, 20-the second annular boss, the 21-flared type mouth of pipe, 3-joint, the outer silk of 4-head, 5-tubular connecting body, 6-helical spring body.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Embodiment
As Fig. 1, shown in 2, a kind of anti-loosening 90 degree exterior plug pepe bends, comprise top straight tube 1, bottom straight tube 2, joint 3 and outer silk 4, between the axis of top straight tube 1 and bottom straight tube 2, form 90 degree angles, top straight tube 1 has the first annular boss 10 with joint 3 transition positions, bottom straight tube 2 has the second annular boss 20 with joint 3 transition positions, described connecting tube is curve bend structure, the two ends of connecting tube connect respectively a port of top straight tube 1 and bottom straight tube 2, straight tube 1 another port in described top is connected with outer 4, described outer silk 4 surface are screw thread, straight tube 2 another ports in described bottom are connected with the flared type mouth of pipe 21, the surface of described elbow body is provided with socket joint deep identification and body nominal diameter mark and socket joint direction signs.
A described outer silk free end arranges circular deep gouge, also comprise spring structure, described spring structure has helical spring body 6 and is arranged on the tubular connecting body 5 of the band external screw thread (outside thread) of described helical spring body one end, described spring structure is spirally connected (after connecting with described deep gouge by this tubular connecting body 5, tubular connecting body is threaded with deep gouge, and helical spring body is to be positioned at outside deep gouge).
After installing, spring body can be to outer first stress of silk, contributes to outer silk head and a first watch of taking over to add firmly and be connected, the in the situation that of external force vibration, the utility model joint is difficult for loosening, connects more tight, sealability is better, and the situation such as effectively prevent from leaking occurs.
Preferably, the dead in line of the axis of described spring structure and described outer silk head, described helical spring body 6 axial lengths are not more than 2cm.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
