Abstract
A quick-assembly ventilating duct connecting flange comprises a first section and a second section which are connected, wherein a through hole for a self-tapping screw to penetrate through is processed at the end part of the first section, a plurality of pressing ribs formed by punching are arranged at the end part of the second section, the self-tapping screw is screwed into the pressing ribs through the through hole, and the quick assembly of the first section and the second section is realized, wherein the pressing ribs are divided into a first pressing rib protruding to one side surface of the second section and a second pressing rib protruding to the other side surface of the second section, and the pressing ribs are distributed on two sides of the second section in a staggered manner, so that the connecting structure is more stable after the self-tapping screw is screwed in; the rib pressing is obtained through punching at the connecting part of the second section, the process is simple, unnecessary material waste is avoided, the cost is saved, and the first section and the second section are assembled very quickly and efficiently.
Description
Technical Field
The utility model relates to a ventilating duct connecting flange capable of being assembled quickly.
Background
Flange for air pipe generally is rectangular frame structure by two sets of section bar fixed connection, along with the simplification of technology, the connection of section bar is realized through self-tapping screw to the general directness of present workshop, like in the utility model patent of application number 2014207514637, section bar II has the circular arc hole along long limit direction integrated into one piece, fixed connection can be realized in self-tapping screw in circular arc hole promptly, integrated into one piece obtains the process in circular arc hole and is inconvenient on the section bar, lead to manufacturing cost to rise, and the circular arc hole is continuous along long limit direction, there is the extravagant problem of certain raw and other materials.
Disclosure of Invention
Aiming at the defects existing in the problems, the utility model provides a ventilating duct connecting flange which is fast to assemble.
In order to achieve the purpose, the utility model provides a quickly-assembled connecting flange for a ventilation pipeline, which comprises a first section bar and a second section bar which are connected, wherein a through hole for a self-tapping screw to pass through is processed at the end part of the first section bar, a plurality of press ribs formed by punching are arranged at the end part of the second section bar, and the self-tapping screw is screwed into the press ribs through the through hole, so that the quick assembly of the first section bar and the second section bar is realized;
the rib pressing is obtained through punching at the connecting part of the second section, the process is simple, unnecessary material waste is avoided, the cost is saved, and the first section and the second section are assembled very quickly and efficiently.
As a further improvement of the scheme, the press rib is divided into a first press rib protruding to one side surface of the second profile and a second press rib protruding to the other side surface of the second profile;
in the technical scheme, the pressing ribs are distributed on two sides of the second sectional material in a staggered manner, so that the connecting structure is more stable after the tapping screw is screwed in.
Compared with the prior art, the utility model has the beneficial effects that: the existing connecting flange for the ventilation pipeline is high in manufacturing cost and has the phenomenon of material waste, the connecting flange for the ventilation pipeline is convenient to machine, no material waste exists, and the quick assembly can be realized.

FIG. 2 is a side view of a quick assembly ventilation duct attachment flange of the present invention;
fig. 3 is an enlarged view of the position a in fig. 2.
In the figure: 1. a first profile; 11. a through hole; 2. a second profile; 21. pressing ribs; 3. a self-tapping screw.
Detailed Description
As shown in fig. 1, 2 and 3, a quick assembly ventilation duct connecting flange according to an embodiment of the present invention includes a first section bar 1 and a second section bar 2 connected to each other, a through hole 11 for a tapping screw 3 to pass through is processed at an end of the first section bar 1, a plurality of press ribs 21 formed by punching are provided at an end of the second section bar 2, and the tapping screw 3 is screwed into the press ribs 21 through the through hole 11, so as to realize quick assembly of the first section bar 1 and the second section bar 2; wherein, the bead 21 divide into protruding to the first bead of 2 side of second section bars and protruding to the second bead of 2 another side of second section bars, and the bead is crisscross to be distributed in the both sides of second section bar for connection structure is more stable after the self-tapping screw in.
The rib is obtained at the connecting part of the second section through punching, the process is simple, unnecessary material waste is avoided, the cost is saved, and the first section and the second section are assembled very quickly and efficiently; the existing connecting flange for the ventilation pipeline is high in manufacturing cost and has the phenomenon of material waste, the connecting flange for the ventilation pipeline is convenient to machine, no material waste exists, and the quick assembly can be realized.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
