Description

Corner protector for flange and flange connection structure

Technical Field

The utility model relates to a flange joint technical field especially relates to a corner protector and flange joint structure for flange.

Background

In the prior art, the length of the ventilation pipeline is formed by connecting a section of air-saving pipe according to the ventilation distance, so that the connection position of the ventilation pipeline needs to be fixedly connected by adopting a flange. At present, the flanges for connecting the smoke-preventing type air pipes are mostly angle steel flanges, common plate flanges and the like, wherein the angle steel flanges are common, the flanges are made of angle steels with different sizes, and the stability of the angle steel flanges is good.

Taking a rectangular air pipe as an example, four sections of flanges are generally inserted into four edges of the air pipe for fixing, and the four sections of flanges are connected by four transition right angles of the air pipe. In this section of the process, the end of each section of flange is typically cut to a 45 ° angle, spliced adjacent to each other to form a 90 ° angle to fit the duct, and then manually fixed to complete the installation. In the process, due to the existence of the cut angle, the connecting edge of the flanges is sharp, and an operator is easily cut.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a corner protector and flange joint structure for flange.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a corner protector for a flange comprises a first fixing surface and a second fixing surface which are connected with each other, wherein the first fixing surface is used for being fixed with a flange neck at one side of the flange, and the second fixing surface is used for being fixed with a flange neck at the other side of the flange;

the inner side of the bottom of the first fixing surface and/or the second fixing surface is provided with an embedded plate which is turned upwards, and the embedded plate is used for being inserted into a gap between the flange neck and the mounting piece to realize pre-fixing.

Preferably, all be provided with the rivet connection position on first stationary plane and the second stationary plane, through rivet and flange neck fixed connection.

Preferably, the inner sides of the bottoms of the first fixing surface and the second fixing surface are respectively provided with an embedded plate which is turned upwards.

Preferably, the first fixing surface and the second fixing surface form an angle of 90 °.

The flange connecting structure is characterized in that the corner protector for the flange is embedded into the butt joint of the flange, the corner protector is embedded between the flange and the mounting piece through the embedded plate, and the corner protector is fixed with the flange neck adjacent to the butt joint by the rivet.

Has the advantages that: the utility model discloses butt joint department to the flange carries out the angle bead design, and the bottom of this angle bead accessory has the embedding board, and in use inserts the embedding board earlier between flange neck and the tuber pipe, realizes fixing in advance, then recycles the rivet and fixes accessory and the adjacent flange neck of butt joint department, realizes the closure of flange and the connection of tuber pipe. The stability of the flange is improved to wrap the corner cut edge of the flange, and the effect of protecting an installer is also played.

Fig. 3 shows an integrally formed flange structure as mentioned in the background art.

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.

Referring to fig. 1 and 3, the corner protector of this embodiment is applied to the butt joint technology of flanges, and referring to fig. 3, a position a in the figure is a 45 ° corner cut of adjacent flange edges (the complete flange is composed of four flange edges, so there are four corners in the figure).

The flange 1 is integrally formed, and the butt joint of the cutting corners (A in the figure) is fixed by the corner protectors. Specifically, referring to fig. 1 and 2, the flange includes a first fixing surface 20 and a second fixing surface 200 connected to each other, and the two fixing surfaces form an angle equal to the angle of the flange neck, such as a 90-degree angle when the present embodiment is applied to a rectangular flange.

The first fixing surface 20 is used for fixing with one side flange neck 11 of the flange 1, and the second fixing surface 200 is used for fixing with the other side flange neck 12 of the flange;

the bottom inner side of the first fixing surface 20 and/or the second fixing surface 200 has an insert plate 22 (in this embodiment, the insert plate 22 is provided on both fixing surfaces), and the insert plate 22 is used for being inserted into a gap between the flange neck and the mounting member, so as to realize pre-fixing.

With continued reference to fig. 1, during installation, the embedded plate 22 is inserted into the flange neck and the mounting member (e.g., the air duct, or other application scenarios), and after pre-fixing is achieved, it is not necessary to additionally fix the embedded plate on the flange, and then the embedded plate can be driven into the preset installation position 21 by using rivets, so as to complete the installation and connection of the corner protector and the flange.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
