Further, the opening direction of the upper opening and the lower opening forms an angle of 90 degrees.

Further, the little radius of curvature of pitch arc main part with the big radius of curvature of pitch arc main part is the same, the radius of the central line of pitch arc main part is less than the little radius of curvature of pitch arc main part, just the little centre of a circle of curvature of pitch arc main part the big centre of a circle of pitch arc main part with the central line centre of a circle of pitch arc main part is located same straight line.

The technical scheme can show that the utility model has the advantages that: the arc main body is integrally formed, so that the arc main body can have strength better, the defects of insufficient strength or incapability of ensuring welding quality and the like are overcome, a welding link is omitted, and the production efficiency is improved; the reinforcing ribs are arranged, so that the strength of the steel plate is high, and the steel plate is not easy to deform; due to the arrangement of the protective sleeve, the application is prevented from being damaged by external force to influence use; because holding tank intussuseption is filled with puigging or heat preservation, therefore can make this application have heat preservation effect or syllable-dividing effect, convenient to use according to the use occasion.

In addition to the objects, features and advantages described above, other objects, features and advantages of the present invention are also provided. The present invention will be described in further detail below with reference to the drawings.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.

FIG. 1 is a schematic structural diagram of the present invention.

List of reference numerals: arc line main part 1, strengthening rib 2, protective sheath 3.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and 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.

As shown in fig. 1, reducing elbow, including the elbow main part, the elbow main part includes integrated into one piece and upper and lower open-ended pitch arc main part 1 and a plurality of strengthening

rib strip

2, 1 integrated into one piece of pitch arc main part can have intensity better, has avoidd intensity inadequately or shortcoming such as welding quality can't guarantee, and has avoided the welding link, has improved production efficiency, the internal diameter of pitch arc main part 1 is reducing and by upper shed department to under shed crescent, just the upper shed with the under shed's opening direction becomes the angle and is 90 degrees, and a plurality of strengthening rib strip 2 are equidistant welding setting of slope spiral and are in the outer wall of pitch arc main part 1 is surperficial, strengthening rib strip 2's setting makes this application intensity big, non-deformable, long service life.

Preferably, this application still establishes including the cover protective sheath 3 in the elbow main part outside, the both ends opening part of protective sheath 3 all is equipped with the turn-ups strip of inside extension, turn-ups strip hook is established the tip of the correspondence of strengthening rib strip 2, the setting of turn-ups strip is avoided protective sheath 3 with the elbow main part produces the dislocation and influences the protection effect, wherein, protective sheath 3 adopts rubber materials to make, avoids external force to the elbow main part causes fish tail or bruise and influences life.

Preferably, both ends face of strengthening rib strip 2 all for the terminal surface that corresponds of pitch arc main part 1 inwards contracts a certain distance, just the terminal surface distance of contracting in of strengthening rib strip 2 is greater than the thickness of turn over the strake, avoid strengthening rib strip 2 with protective sheath 3 influences the connection installation of elbow main part.

Form the holding tank between two adjacent strengthening rib 2, the holding tank intussuseption is filled with puigging or heat preservation, protective sheath 3 will puigging or heat preservation are injectd in the holding tank, avoid puigging or heat preservation with the holding tank breaks away from, adopts above-mentioned structure, can make this application have heat preservation effect or syllable-dividing effect according to the user demand.
