Problems solved by technology

[0002] Brackets play an important role in daily production. They can not only be used to hang objects, but also facilitate the transportation of objects. The earliest brackets are all fixed, and the length and curvature are generally not adjustable. However, with the development of technology, people A bracket with adjustable length and curvature has been developed, but it is often found that the elbow is easy to slip when using this type of bracket. In the prior art, an interference fit is generally used between the elbow and the aluminum alloy tube. This type of fit Make the connection strength between the elbow and the aluminum alloy pipe weak

Abstract

The invention discloses a connecting structure for aluminum alloy pipes and a self-locking bend device. The connecting structure comprises the first aluminum alloy pipe, the second aluminum alloy pipe and the self-locking bend device. The self-locking bend device comprises a first bend and a second bend. The first bend comprises a first body and a first pipe joint. The second bend comprises a second body and a second pipe joint arranged on one side of the second body. The first body and the second body are in butt connection. The first pipe joint is sleeved with the first aluminum alloy pipe. A first cylindrical pin is inserted into the overlapped position of the first aluminum alloy pipe and the first pipe joint. The two ends of the first cylindrical pin are welded to the first aluminum alloy pipe. The second pipe joint is sleeved with the second aluminum alloy pipe. A second cylindrical pin is inserted into the overlapped position of the second aluminum alloy pipe and the second pipe joint. The two ends of the second cylindrical pin are welded to the second aluminum alloy pipe. The connection strength between the aluminum alloy pipe and the pipe joints is greatly improved.

Description

technical field [0001] The invention relates to a connection structure between an aluminum alloy tube and a self-locking elbow device. Background technique [0002] Brackets play an important role in daily production. They can not only be used to hang objects, but also facilitate the transportation of objects. The earliest brackets are all fixed, and the length and curvature are generally not adjustable. However, with the development of technology, people A bracket with adjustable length and curvature has been developed, but it is often found that the elbow is easy to slip when using this type of bracket. In the prior art, an interference fit is generally used between the elbow and the aluminum alloy tube. This type of fit This makes the connection strength between the elbow and the aluminum alloy pipe weak. [0003] Therefore, it is necessary to provide a connection structure between an aluminum alloy tube and a self-locking elbow device that solves the above technical pro...
