Wherein the body 11, the flange 12, the outer closure plate 15 and the bottom closure plate 16 are welded together to form a substantially enclosed space 17, the plurality of inner support plates 13 are disposed in the space to provide support for the flange 12, and the plurality of outer support plates 14 are disposed below the bottom closure plate 16 and welded to the bottom closure plate 16 and the body 11 to provide support for the bottom closure plate 16.

According to one aspect of the present invention, the inner support plate 13 is welded to the bottom closure plate 16, the flange 12 and the main body 11.

According to the utility model discloses a technical scheme, a plurality of interior backup pads 13 set up respectively square hollow flange is all around.

According to a technical scheme of the utility model, interior backup plate 13 is square.

According to the utility model discloses a technical scheme, outer backup pad 14 is triangle-shaped, and two limits weld respectively on end closure plate 16 and main part 11.

According to the utility model discloses a technical scheme, a plurality of outer backup pads 14 set up respectively square hollow flange is all around.

According to an aspect of the present invention, a sealing groove 121 is further formed on the flange 12.

Detailed Description

For the purpose of clearly illustrating the aspects of the present invention, preferred embodiments are given below in conjunction with the accompanying drawings. The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

Fig. 1 is a schematic top view of a square hollow flange according to an embodiment of the present invention; FIG. 2 is a schematic cross-sectional view along line AA' of the square hollow flange shown in FIG. 1; fig. 3 is a schematic cross-sectional view of the square hollow flange shown in fig. 1 along line BB'.

Referring to fig. 1 to 3, the square hollow flange of the present invention may include a main body 11, a flange 12, a plurality of inner support plates 13, a plurality of outer support plates 14, an outer closure plate 15, and a bottom closure plate 16.

The main body 11 is substantially in the shape of a square hollow cylinder, and a flange 12 is formed around the top. A plurality of connection holes may be formed on a surface of the flange 12 and a sealing groove 121, and a sealing ring may be disposed in the sealing groove 121 when connection is performed using the connection holes.

referring to fig. 2 and 3, the flange 12 of the present invention is thin compared to a conventional solid flange, and a bottom closure plate 16 is formed in parallel below the flange 12 at a distance, and has a shape substantially identical to the flange 12. The body 11, the flange 12 and the bottom closure plate 16 are formed together substantially asThe main body 11, the flange 12, and the bottom closure plate 16 may be welded together by welding, for example. Together with the outer closing plate 15, a substantially closed space 17 is formed as a whole. The outer closure plate 15 can be closed, for example welded closed, at the end of the process after the square hollow flange has been applied to the connection of the actual pipe.

Referring to fig. 3, a plurality of inner support plates 13 may be disposed in the space 17, for example, the inner support plates 13 may be square, and welded to the bottom closure plate 16, the flange 12, and the main body 11 to provide support for the flange 12. The plurality of inner support plates 13 may be arranged around the square hollow flange, for example, at positions between the coupling holes, below the flange 12, respectively.

The plurality of outer support plates 14 are disposed below the bottom closure plate 16, such as by welding, over the bottom closure plate 16 and body 11 to provide support to the bottom closure plate 16. According to the utility model discloses a technical scheme, outer backup pad 14 is triangle-shaped, and two limits weld respectively on end closure plate 16 and main part 11. For example, the plurality of outer support plates 14 may be respectively disposed around the square hollow flange. For example, directly below the inner support plate 13, or at a position offset from the inner support plate 13. In the embodiment shown in fig. 2 and 3, the two positions are staggered.

The utility model discloses square hollow flange adopts thinner flange and hollow structure, and inside equipartition welding inner support plate improves closure plate welding strength, and outside welding outer support plate improves bulk strength, and the deflection is little after the whole welding, light in weight. That is, the utility model has the advantages of intensity is high, light in weight and do benefit to a great deal of such as processing.

The principle and the implementation of the present invention are explained herein by using specific examples, and the above description of the embodiments is only used to help understand the device and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
