Abstract
The utility model discloses a non-flange air duct connected in a hoop mode and used for rectangular air ducts and circular air ducts. The utility model is composed of an air duct, a hoop, a locking mechanism, a sealing ring and a rivet, wherein, the hoop forms a U shape corresponding to a flange of the pipe end of a clamping air duct; the top edge of the hoop is connected and fixed with the wall of the air duct by the rivet; two bottom sides of the hoop are fixed by the locking mechanism. The utility model has no evagination flange mechanism; the arc face of the hoop is used for hooping the flange of the pipe end of the air duct; the utility model has the advantages of fastening connection, good sealing effect, convenience and practicability.
Description
The utility model relates to a kind of ventilation duct, particularly a kind of flangeless wind pipe that is applicable to that rectangular air duct or garden shape airduct adopt locking hood type to connect.
Existing airduct connects, and adopts flange arrangement, and the bulk that occupies is bigger, bring difficulty to construction and installation, and have can't blue structure airduct because Placement is unreasonable, complex structure, it is not fastening to cause airduct to connect, and sealability is the poor stability of axial restraint particularly, the cost height.
Goal of the invention of the present utility model is intended to overcome above-mentioned shortcoming, a kind of locking hood type flangeless wind pipe is provided, this airduct is applicable to makes rectangular air duct and garden shape airduct, the flange arrangement of the no evagination of airduct self, saved the bulk that air duct flange occupies, airduct connects fastening, and sealing and axial restraint performance are good, convenient and practical, beautiful shape.
Goal of the invention of the present utility model is achieved in that
The utility model is made up of airduct, anchor ear, locking mechanism, seal ring, rivet, there is chimb (platform) at the airduct two ends, be lined with seal ring between the airduct, it is characterized in that: anchor ear is " " shape, two bases have attachment hole, and top margin has fixed hole, two the corresponding bag card of anchor ear two airduct chimbs, and the top margin and the wind pipe wall of anchor ear are connected and fixed with rivet through fixed hole, and anchor ear two bases are fixedly connected with locking mechanism.
Rectangular or the garden shape of the utility model airduct.
The cross section of the utility model anchor ear is " " shape.
The utility model locking mechanism comprises connecting bolt nut, buckle etc.
The no evagination flange of the utility model airduct self mechanism, saved the bulk that air duct flange occupies, solved the connection of flangeless wind pipe and the traditional air duct flange structure larger-size drawback that takes up space, utilize the arc shaped surface of anchor ear to encase the chimb (platform) of airduct end, and have rivet to fix, thereby realize the fastening of airduct, sealing and axial restraint, simple and reliable for structure, convenient and practical, beautiful shape.
Provide accompanying drawing of the present utility model below:
Fig. 1 left sight plane structural representation of the present utility model
The plane structure schematic representation cuts open in Fig. 2 the utility model office of facing
Fig. 3 the utility model structural representation
The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model is by airduct 1, anchor ear 2, locking mechanism 3, seal ring 4, rivet 7 is formed, there is chimb 5 at airduct 1 two ends, be lined with seal ring 4 between the airduct 1, it is characterized in that: anchor ear 2 is " " shape, and two bases 10 have attachment hole 6, top margin 9 has fixed hole 8, two anchor ears, 2 corresponding bag card two airducts 1 chimbs 5, and the top margin 9 of anchor ear 2 is connected and fixed through fixed hole 8 usefulness rivets 7 with airduct 1 wall, and 2 liang of bases of anchor ear, 10 usefulness locking mechanisms 3 are fixedly connected.
The utility model airduct 1 is rectangular.
The cross section of the utility model anchor ear 2 is " " shape.
As Fig. 1 locking mechanism is the connecting bolt nut.
The no evagination flange of the utility model airduct 1 self mechanism, saved the bulk that air duct flange occupies, utilize the arc shaped surface of anchor ear 2 to encase the chimb (platform) 5 of airduct 1 end, and there is rivet 7 fixing, thereby realize the fastening of airduct 1, sealing and axial restraint, simple and reliable for structure, convenient and practical, beautiful shape.
