Abstract
The utility model relates to ventilation duct installation field, in particular to a hidden flanged connection structure for composite air duct. The utility model is characterized in: one end of the flange is connected to the air duct, and the other end is arranged with a notch groove that is coupled to an I-shape bar, wherein, the top and bottom flanges of the I-shape bar are inserted into the notch grooves of two flanges that are back-to-back to each other. The utility model has the following advantages: simple structure, easy and firm assembling, high rigidity and strength, and high stability; in addition, the outer diameter of the flanges is reduced appropriately, and therefore the overall size of the air duct is reduced, and space occupation is effectively reduced; the air duct has a neat and esthetic appearance, and is corrosion resistant; in addition, the air duct can be assembled without bolts, and thereby is time and material saving, and can reduce the cost.
Description
Technical field:
The utility model relates to ventilation duct mounting technique field, refers in particular to a kind of composite air duct hidden method flange connection structure.
Background technique:
Ventilation duct generally all is to be interconnected by the plurality of sections airduct to constitute, and the Placement of airduct is the flange connection.The flange of current employing is an angle steel flange, and its external diameter by the angle steel flange of bolt-through two butt joints, cooperates the corresponding nut interlocking greater than the external diameter of airduct when connecting combination again.This Placement has following shortcoming: 1, because flange protrudes around the outer wall of airduct, the entire outer diameter size of airduct is increased, occupy space; 2, because flange adopts bolt to connect, need to process in advance some through holes on the flange, install and need consume a large amount of bolts and mounting or dismounting man-hours during dismounting, take a lot of work, time-consuming, expense material, and work efficiency is low; 3, since flange evagination air outlet tube around, not only influence attractive in appearancely, and corrosion easily takes place in the bolt part on it, finally causes damaging.
As shown in Figure 1, other has a patent No. is " airduct quickset type flange connecting apparatus " utility model patent of 00223502.1, one end of its flange 03 is connected with airduct 01, the other end is provided with groove and pegs graft for the cutting 04 of door font, and thisly be connected to one-sided connection, and only transplant a cutting 04 dual-side to drawing by the door font, dual-side very easily is out of shape loosening in the use, connect hardness and strength deficiency, poor stability.
Summary of the invention:
The purpose of this utility model is to overcome the defective of prior art, and provide a kind of and reduce the shared space of flange, and simple in structure, assemble and dismantle all composite air duct hidden method flange connection structure very easily, the hardness and the intensity of its connection are higher.
For achieving the above object, the utility model includes airduct and flange, wherein an end of flange is connected with airduct, the gap slot that the other end of flange is provided with is transplanted a cutting with " worker " font and is connected, and wherein two flanges up and down of " worker " font cutting are inserted in respectively in the gap slot of mutual back-to-back two flanges.
The end of described flange also is provided with inserting groove and plugs with the eye-splice of outsourcing hornblock and be connected.
The utlity model has following advantage: simple in structure, easy to assembly, firm, pull and support flange by I-shaped cutting symmetry, the hardness and the intensity of connection are higher, good stability; Simultaneously the external diameter of flange reduces relatively, the airduct overall volume is dwindled and effectively reduces taking of space, and the appearance of airduct is neat and artistic, is difficult for corrosion, and need not bolt and connect, and the saving of work and time material saving reduces cost.

Accompanying drawing 2 is the utility model linkage structure schematic representation;
Accompanying drawing 3 is the utility model combination profile schematic representation;
Accompanying drawing 4 is the partial enlarged drawing of the utility model composite structure;
Accompanying drawing 5 is the schematic perspective view of flange of the present utility model and cutting;
Accompanying drawing 6 is the section configuration schematic representation of flange of the present utility model and cutting.
Embodiment:
See shown in the accompanying drawing 2～6 that the utility model includes airduct 1 and flange 2, airduct 1 is square hollow article, and an end of flange 2 is connected with airduct 1.Wherein the end that is connected with airduct 1 of flange 2 is provided with " U " shape groove and is convenient to the connecting end of airduct 1 and embeds, the other end of flange 2 is provided with gap slot 21 and is connected with " worker " font cutting 3,3 two flanges up and down of wherein transplanting a cutting are inserted in respectively in the gap slot 21 of back-to-back two flanges 2 mutually, thereby connect plurality of sections airduct 1 in aggregates.The end of flange 2 also is provided with inserting groove 22 and plugs with the eye-splice 51 of outsourcing hornblock 5 and be connected, so that the bent angle position of flange 2 is hidden, increases aesthetics.
During assembling, two sections airducts 1 that are connected with flange 2 are respectively docked mutually, so that two flanges, 2 back-to-back the reclining on the two pairs of air ducts 1, at this moment will transplant a cutting again in 3 gap slots 21 that insert on the flanges 2, wherein, two flanges up and down of " worker " font cutting 3 are inserted in respectively in the gap slot 21 of mutual back-to-back two flanges 2, be about to plurality of sections airduct 1 and connect and compose an integral body, and two flanges up and down of I-shaped cutting 3 are symmetric design, cutting 3 is stressed even when connecting use, improved airduct 1 assembling back hardness and intensity, good stability.Cornerite piece 5 is loaded onto at last, wherein the eye-splice on the cornerite piece 5 51 is inserted in the inserting groove 22 of flange 2 again.The utility model beautiful shape is generous, and the external diameter of adpting flange 2 dwindles greatly, and almost consistent with the external diameter of airduct 1, shared building Kongxiang is beneficial to installation to dwindling.
