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 in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the present invention, unless otherwise expressly stated or limited, the terms "disposed," "mounted," "connected," "fixed," "sleeved," and the like are to be construed broadly, e.g., as either a fixed connection, a removable connection, or an integral part; can be mechanically or electrically connected; the two elements may be connected directly or indirectly through an intermediate medium, and the two elements may be connected internally or in an interaction relationship, and a person skilled in the art can understand the specific meaning of the above terms in the present invention according to specific situations.

Referring to fig. 1-4, the present invention provides a technical solution: take neck flush joint flange, including flange main part 1, the neck post 2, permanent magnet 3, connecting hole 4, the gag lever post 5, the spacing groove 6, through-hole 7, wear-resistant rubber 8, nickel coating 9 and chromium coating 10, be provided with the neck post in the middle of the top of flange main part, the surface mosaic of neck post has wear-resistant rubber, the top of neck post and flange main part runs through there is the through-hole, the top of flange main part runs through there is the connecting hole, the bottom of flange main part is provided with the permanent magnet, make the flange carry out seamless connection, the connection effect is better, the bottom of permanent magnet is provided with gag lever post and spacing groove respectively, the inner wall of through-hole is provided with the nickel coating, one side of nickel.

Referring to fig. 1-4, a plurality of connecting holes are arranged, the connecting holes are circumferentially arranged on the top of the flange main body and penetrate through the top of the flange main body, the connecting holes 4 can be used for enabling the flanges to be connected more firmly according to a plurality of bolts, and the outer surfaces of the flange main body and the neck post are coated with anti-rust paint, so that the flanges are prevented from rusting, and the service life of the flanges is prolonged.
