Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a flange convenient to install comprises a flange I1 and a flange II 3, wherein a sleeve 5 is fixed on the side wall of the flange I1, the flange I1 is welded with the sleeve 5, the sleeve 5 is distributed at equal angles around the center of the flange I1, a moving pin 6 penetrates through the end part of the sleeve 5, the moving pin 6 is in sliding fit with the sleeve 5, a flange 7 is formed at one end of the moving pin 6, the diameter of the flange 7 is larger than that of the moving pin 6, a U-shaped limiting pin 4 is fixed at the other end of the moving pin 6, a spring 8 is sleeved outside the moving pin 6, two ends of the spring 8 are respectively contacted with the flange 7 and the inner side wall of the sleeve 5, under the action of the spring 8, the moving pin 6 and the limiting pin 4 can be provided with elastic force close to the flange I1, a through hole 9 and through grooves 10 formed at two sides of the through hole 9 are arranged on the flange II 3, the through hole 9 is matched with the sleeve, the second flange 3 is provided with a limiting hole 11 matched with the limiting pin 4, the limiting hole 11 is symmetrically arranged relative to the through groove 10, the limiting pin 4 is clamped with the limiting hole 11, the limiting pin 4 can be limited, and the limiting pin 4 is prevented from rotating randomly.
