Air port

Abstract

The invention discloses an air inlet, which is characterized in that the air inlet comprises a square air inlet outer frame and wind blades which are arranged in the square air inlet outer frame, wherein the square air inlet outer frame is formed by connecting four aluminum alloy sections which are butted at an angle of 45 degrees, each aluminum alloy section consists of a panel part and a air inlet wall part which is perpendicular to the panel part, the backside of the panel part of the aluminum alloy section is provided with an inlay groove, a right-angle fixing sheet is arranged in the inlay groove, and a right-angle type connecting clamp is formed on the right-angle air inlet wall formed by butting the two aluminum alloy sections at the angle of 45 degrees. Compared with the prior art, the air inlet has the advantages of firm connection, quality assurance, compact and smooth connection of connecting surfaces and high manufacturing efficiency.

Description

Technical field: [0001] The invention relates to a tuyere. Background technique: [0002] The existing square tuyere for the air-conditioning air inlet and outlet made of aluminum alloy is composed of a square tuyere outer frame and air guide vanes arranged in the square tuyere outer frame, and the square tuyere outer frame is composed of four aluminum alloy profiles connected at an angle of 45° Composition, the joints of the profiles are fixed by welding. This kind of tuyere, because the aluminum alloy profiles that make up the outer frame of the square tuyere are fixed by welding, this fixing method has the following disadvantages: [0003] 1. The workload is heavy, it is not easy to guarantee the quality and the efficiency is low. When welding, only one solder spot can be carried out, which makes the welding workload heavy; affected by the operator's welding skills and sense of responsibility, it is not easy to guarantee the welding quality; moreover, limited by the sha...

AI Technical Summary

Problems solved by technology

[0003] 1. Heavy workload, difficult quality assurance and low efficiency

When welding, only one solder spot can be carried out, which makes the welding workload heavy; affected by the operator's welding skills and sense of responsibility, it is not easy to guarantee the welding quality; moreover, limited by the shape of the tuyere, under normal circumstances , the welding of one tuyere can only be carried out by one person, and it is not easy to improve production efficiency

[0004] 2. During welding, because it is done manually, the 45° joint edges of aluminum alloy profiles are not easy to be tightly bonded together, which not only destroys the overall appearance of the tuyere, but also affects the structural strength of the tuyere
