[0005] In the above-mentioned air inlet elbow, the outer peripheral wall of the elbow main body at screw end is provided with the limit protruding ring that projects radially outward and functions as a limit.

[0006] In the above-mentioned air inlet elbow, the inner wall of the elbow main body at clamping end is provided with several strip grooves that are arranged along its circumferential direction and extend axially inward, the outer peripheral wall of the clamping end at the inner end of strip groove is provided with annular groove, the through hole that makes strip groove and annular groove communicate is provided on the groove bottom surface of strip groove, the clamping end is provided with sealing sleeve connected therewith at annular groove.

[0007] In the above-mentioned air inlet elbow, the two end portions of the expansion part are all provided with the folded edge that is bent into shape and connected with the elbow main body, and the recess is provided on the two end surfaces of the expansion part and recessed axially inward for mounting reinforcing rib.

[0008] In the above-mentioned air inlet elbow, the outer peripheral wall of the elbow main body at expansion part is provided with support block connected therewith and used for connecting support, the connecting hole is provided on the support block, and the recessed groove is provided on one end surface of the support block and recessed axially inward to form reinforcing rib structure.

[0009] Compared with existing technologies, this intake bend improves its structural strength by incorporating reinforcing ribs. Attached Figure Description

[0010] Figure 1 This is a three-dimensional structural diagram of the intake bend.

[0011] In the diagram, 1 is the main body of the bent pipe; 2 is the extension section; 3 is the reinforcing rib; 4 is the strip groove; 5 is the annular groove; and 6 is the support block. Detailed Implementation

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figure 1 As shown, this intake bend includes a bend body 1 with two connecting ends. Two extension portions 2 are provided on the outer peripheral wall of the bend body 1, connected to it and arranged along its length. Several reinforcing ribs 3 are provided on both ends of the extension portions 2, connected to them and spaced apart along their length, for strengthening the structural strength. The two connecting ends of the bend body 1 are a snap-fit ​​end and a threaded end. A limiting ring with radially outward protrusion and limiting function is provided on the outer peripheral wall of the bend body 1 at the threaded end. Several strip grooves 4 are formed on the inner wall of the bend body 1 at the snap-fit ​​end, arranged along its circumference and extending axially inward. An annular groove 5 is formed on the outer peripheral wall of the snap-fit ​​end at the inner end of the strip grooves 4. The annular groove 5 is provided with a through hole on the bottom surface of the strip groove 4 to connect the strip groove 4 and the annular groove 5. The snap-fit ​​end is provided with a sealing sleeve connected to it at the annular groove 5. When the pipe fitting is snapped with the snap-fit ​​end, a sealing ring is provided between the pipe fitting and the snap-fit ​​end to enhance the sealing performance. Both ends of the extension part 2 are provided with bent and folded edges that are connected to the bent pipe body 1.
