Description

Reinforced elbow

Technical Field

The utility model relates to a return bend technical field specifically is a strenghthened type return bend.

Background

The existing elbow is a pipe body frequently used in daily life of people, and can be widely adopted in the fields of sewage discharge, water delivery and indoor wiring, so that the elbow is closely related to the life of people. The elbow pipe that uses at present is the same and the smooth hollow cylinder structure in surface of external diameter mostly, and because the surface of elbow pipe is smooth, does not have the stress point, consequently often takes place the phenomenon of skidding in installation and use, influences staff's installation, has reduced labor efficiency, has improved labour cost. Moreover, the pipe fitting of the existing elbow pipe does not adopt a reinforcing structure, when the pipe fitting of the elbow pipe is connected with other pipe bodies, the sealing performance of the elbow pipe fitting is reduced due to the fact that the elbow pipe fitting is stressed and expanded easily, even the pipe fitting of the elbow pipe is easy to break, and therefore the service life of the elbow pipe is greatly shortened.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a strenghthened type return bend to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a strenghthened type return bend, includes the return bend, connecting portion are installed to two pipe orifices screw threads of return bend, be fixed with first reinforcement and second reinforcement on the mouth of pipe inner wall, first reinforcement and second reinforcement looks joint, flexion in the return bend is equipped with a plurality of arc strengthening ribs, the arc strengthening rib passes through connecting block fixed connection at the return bend inner wall, the straight strengthening rib of both ends fixed connection of arc strengthening rib.

Furthermore, a stress reinforcing block is arranged on the inner side of the bending part of the bent pipe.

Furthermore, first reinforcement and second reinforcement all are hollow cylindrical, just the inner wall of first reinforcement and second reinforcement is equipped with and all is equipped with the internal thread.

Furthermore, the connecting part is also in a hollow cylindrical shape, and a handle convenient for rotating the connecting part is arranged on the connecting part.

Further, an organic whole is connected with the rand on the first reinforcement, be equipped with the draw-in groove on the second reinforcement, rand and draw-in groove cooperation joint.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the connecting part is arranged on the pipe orifice in a threaded manner, so that the connecting pipes with different diameters can be connected, the first reinforcing part and the second reinforcing part are detachably connected through the first reinforcing part and the second reinforcing part arranged in the pipe orifice, more connecting pipes with different diameters can be conveniently connected, and the flexibility of the connecting pipes is higher;

2. the inside arc strengthening rib and straight shape strengthening rib of this kind of return bend make the inside intensive antiskid structure that constitutes of return bend for the return bend is difficult for skidding when connecting the operation.

Fig. 1 is a schematic view of the overall internal structure of the present invention;

fig. 2 is a schematic view of the overall external structure of the present invention;

fig. 3 is a schematic diagram of the structure a of the present invention.

In the reference symbols: 1. bending the pipe; 2. a pipe orifice; 3. a connecting portion; 4. a first reinforcement; 5. a second reinforcement; 6. an arc-shaped reinforcing rib; 7. connecting blocks; 8. a straight reinforcing rib; 9. a stress reinforcement block; 10. a handle; 11. a collar; 12. a clamping groove.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. In which like parts are designated by like reference numerals. It should be noted that as used in the following description, the terms "front," "back," "left," "right," "upper," and "lower" refer to directions in the drawings, and the terms "bottom" and "top," "inner," and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a strenghthened type return bend, includes return bend 1, connecting portion 3 are installed to 2 screw threads in two mouths of pipe of return bend 1, be fixed with first reinforcement 4 and second reinforcement 5 on 2 inner walls in the mouth of pipe,

first reinforcement

4 and 5 looks joints of second reinforcement, the flexion in return bend 1 is equipped with a plurality of arc strengthening ribs 6, arc strengthening rib 6 passes through connecting block 7 fixed connection at 1 inner wall in return bend, the straight shape strengthening rib 8 of both ends fixed connection of arc strengthening rib 6.

The inner side of the bending part of the elbow 1 is provided with a stress strengthening block 9 to reduce the damage of the inner side stress of the elbow 1.

First reinforcement 4 and second reinforcement 5 all are hollow cylindrical, just the inner wall of first reinforcement 4 and second reinforcement 5 is equipped with and all is equipped with the internal thread, is convenient for connect with the connecting pipe of return bend 1 same diameter.

The connecting portion 3 is also hollow and cylindrical, and a handle 10 for facilitating rotation of the connecting portion 3 is disposed on the connecting portion 3.
