TECHNICAL FIELD

[0001] The utility model relates to the field of flange, concretely is a goose neck flange convenient to connect and fix. BACKGROUND

[0002] In the pipeline system, flange connection is a common connection method, which realizes the connection of pipelines or equipment by fastening two flanges together with bolts. Goose neck flange, as a special form of flange, is named for its shape similar to a goose neck, and is often used in scenes where the direction of the pipeline needs to be changed or additional support is provided. However, traditional goose neck flange connection has some problems, such as loose bolts, unstable connection, etc., which may cause pipeline leakage or system failure.

[0003] In order to solve these problems, various improved goose neck flanges have appeared in the market. However, these improvements are mostly focused on the structure and material of the flange, and there is relatively little research on how to enhance the stability of the connection and prevent the bolts from loosening. Therefore, it is particularly important to develop a goose neck flange that can ensure both connection stability and prevent bolts from loosening. SUMMARY

[0004] The utility model aims at providing a goose neck flange convenient to connect and fix to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a goose neck flange convenient to connect and fix, comprising a goose neck flange body, a plurality of bolt holes are formed on the surface of the goose neck flange body, a embedding groove is formed at one end of the bolt hole, a rubber plug pipe is inserted and fixed in the inside of the bolt hole, a rubber grommet is integrally formed on the outer ring surface of the rubber plug pipe, a buckle plate is rotatably connected to the end of the goose neck flange body, a hand screw is screwed on the surface of the buckle plate, and one end of the hand screw is screwed on the outer wall of the goose neck flange body.

[0006] Preferably, the caliber of the embedding groove is larger than that of the bolt hole, the length of the rubber plug pipe is greater than the depth of the bolt hole, and the thickness of the rubber grommet is greater than the depth of the embedding groove.

[0007] Preferably, a cavity is formed in the inside of the rubber grommet, and the cavity is an annular groove.

[0008] Preferably, an installation groove is formed on the outer wall of the goose neck flange body, a limiting shaft is fixed between the two parallel side walls of the installation groove, the limiting shaft penetrates through a through hole, and the through hole is formed at one end of the buckle plate.

[0009] Preferably, the buckle plate is in the shape of a "Fang" character plate structure, and a rubber gasket strip is fixed to the other end of the buckle plate.

[0010] Preferably, the outer wall of the gooseneck flange body is provided with a positioning groove, and one end of the hand screw rod is inserted into the positioning groove.

[0011] Compared with the prior art, the utility model has the advantages that:

[0012] The gooseneck flange is convenient to connect and fix, the rubber plug pipe is installed in the bolt hole, when the gooseneck flange body and the pipe flange are connected, one end of the rubber plug pipe can be inserted into the bolt hole of the pipe flange, when the bolt passes through the bolt hole and the bolt hole, the rubber plug pipe is clamped between the screw rod and the hole, and the random loosening of the bolt is effectively prevented. The design not only enhances the stability of the connection, but also improves the safety of the pipeline system. The rubber gasket ring is integrally formed on the outer ring surface of the rubber plug pipe, and is compressed into the embedded groove after the bolt is locked. The resilience of the rubber gasket ring plays the role of an elastic gasket for the bolt, and further enhances the fastening and stability of the connection. The design enables the gooseneck flange to maintain better sealing performance when bearing pressure or vibration. The end of the gooseneck flange body is rotationally connected with the buckle plate, and the hand screw rod is screwed on the buckle plate, so that the buckle plate can be rotated and the gooseneck flange body and the pipe flange can be gripped on the outside when the bolt passes through the hole and is not locked. At this time, the rubber gasket strip is tightly clamped between the end of the buckle plate and the pipe flange, so that the gooseneck flange body and the pipe flange are tightly attached. The design not only simplifies the connection process, but also improves the work efficiency. BRIEF DESCRIPTION OF DRAWINGS
