Abstract
The utility model discloses a connecting device of a fast installed air duct for the connection of the outlet seat and the air duct of the cooker hood. The connecting device includes a connecting ring which is connected with the outlet seat and the air duct respectively. The end part of the air duct is provided with a flange. The connecting ring is sheathed on the air duct and positioned by the flange. The outlet seat and the connecting ring are rotationally buckled through a positioning block. Therefore, the air duct can be assembled rapidly only by looping the outlet seat with the air duct connecting ring and a certain angle is rotated after positioning. Compared with the prior art, the installation of four screw nails can be saved. When in repair, the air duct can be disassembled rapidly and the air duct can be separated from the outlet seat only by reverse rotation for a little angle. Besides, a circle of the sealing pad can be added at the head part of the air duct and oil leaking can be avoided after installation. Therefore, when the air duct and the outlet seat are connected in place, the effect of slip proofing and oil leakage proofing can be achieved.

The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of connection set of quick mounting airduct, be used to connect the exhaust outlet seat and the airduct of range hood, it is characterized in that: described connection set comprises respectively the fastener rings that is connected with airduct with the exhaust outlet seat, described airduct end is provided with flange, fastener rings is sleeved on the airduct and by the flange location, exhaust outlet seat and fastener rings are fastened and connected by the positioning block rotation.
Described positioning block is evenly distributed on the exhaust outlet seat outer side wall, fastener rings is to comprise that inwall and outer wall, cross section are the ring of U type, the breach that the inboard of fastener rings outer wall is provided with is suitable with positioning block, extend along the outer wall short transverse, be provided with in the bottom of outer wall inboard along outer wall extending circumferentially and the groove that is interconnected with this breach, described positioning block rotation snaps in this groove.
Described positioning block is provided with cammed surface, and the geomery of groove is corresponding with the geomery of positioning block.
The position corresponding with groove, the outside of described fastener rings is provided with and the corresponding through hole of the geomery of positioning block.
The position corresponding with groove, the bottom of described fastener rings is provided with and the corresponding through hole of the thickness size of positioning block.
The described fastener rings outside is provided with projection with the corresponding position of breach.
As further improvement of the utility model, the cross section on described exhaust outlet seat top is the U type, comprises outer ring and inner ring, and described inner ring matches with the internal diameter of airduct, matches with the internal diameter of fastener rings outer wall in the outer ring.
Further improve as of the present utility model, be provided with seal ring between the U type groove bottom on the end face of described airduct and exhaust outlet seat top.
This range hood exhaust outlet seat and the connection set that airduct is connected quickly and easily of being used for increases by a fastener rings on the original basis, adopts the rotary clamping mode that exhaust outlet seat and airduct are connected and fixed by fastener rings.Only need during assembling fastener rings is enclosed within on the airduct, again fastener rings is inserted in the exhaust outlet seat, when the breach of fastener rings aim at the positioning block of exhaust outlet seat insert after, just rotating to an angle can the good air outlet tube of quick mounting, will adorn several screws need not to resemble originally to install.And, all have cammed surface because the positioning block on exhaust outlet seat top is consistent with the groove shapes of airduct fastener rings, can't get loose automatically after being rotated in place.And when repair demolition, again by suitable or rotation counterclockwise, rotate to an angle and just can separate fastener rings and exhaust outlet seat after only needing to defeat on earth toward end with some fastener rings, thereby separate airduct and exhaust outlet seat along the breach direction.
Description of drawings:
Below in conjunction with the drawings and specific embodiments connection set of the present utility model is further described:
Accompanying drawing 1 is the sectional view of the utility model connection set;
Accompanying drawing 2 is the right elevation of Fig. 1;
