Description

Technical Field

[0001] The utility model relates to the field of pipe buckles, in particular to a three-purpose buckle suitable for flagpoles and pipes. Background Art

[0002] With the development of industrial modernization, more and more products require round tube materials. The clip is an indispensable component in the round tube assembly process, which can connect and fix two round tubes.

[0003] There are many existing means for connecting and fixing round tubes, which can realize different connections and fixations between round tubes. However, in order to ensure a stable connection between the round tubes, the buckles in the prior art are generally set to a single specification, so that the buckles can only provide connection and fixation for round tubes of the same diameter. For example, the following website is disclosed, and the specific website is as follows:

[0004] 1. https: / / www.vipmro.com / product / 81381462

[0005] 2. https: / / detail.1688.com / offer / 646372797919.html?spm=a261b.124363 57.ul20190116.43.6cd34a27TXR8CD

[0006] 3. https: / / www.zhe2.com / note / 643835302000

[0007] The above website specifically discloses a double-hole fixed pipe rack, but they can only be set to a single inner diameter size, so that they can only be used to clamp pipes of a single diameter. Although these clips can roughly meet the use requirements, their designs are not clever enough and they have not broken through the traditional structural design. When assembling round pipes of different diameters, clips with suitable inner diameters are required to complete the assembly. There will be many types of clips and a large amount of space occupied, resulting in a waste of space resources and an overall high cost. In addition, too many accessories will cause assembly confusion, affecting its assembly efficiency. In addition, multiple clips will generate greater noise during the assembly process, which will have a certain impact on the surrounding production environment. Utility Model Content
