Description
Technical field
Pipe fitting technical field is the utility model is related to, more particularly, to a kind of structure of family kitchen and bath ventilation duct.
Background technology
Family's kitchen and bath's ventilation duct one end is ined succession ventilation blower, and the other end is ined succession exhaust duct connecting tube.Because ventilation blower acts on
Difference, if kitchen is mainly mist extractor, and toilet is mainly taken a breath and exhaust, and the diameter of the ventilation blower connection mouth of pipe also differs
Sample.So requiring the ventilation duct of distinct interface could meet.In order to solve this problem Chinese patent Authorization Notice No.
CN201053739Y, authorized announcement date on April 30th, 2008, the practicality of entitled " a kind of ventilation shaft with coupling flange "
New patent, there is provided one kind ventilation tubular construction.It includes airduct, has flange framework in the end face of airduct, in flange framework
There is annular seal groove on end face, have bolt hole on flange framework, have bonding agent in the annular seal groove of flange framework；Airduct end
The flange framework in face is folded by the extended surface of airduct and formed, and the corner of flange framework is by the orientation angle structure that is nested on flange framework
Into the bolt hole on flange framework is in orientation angle；Two sections of airducts are connected by bolt through the bolt hole on flange framework, flange frame
Frame is fixed by geometrical clamp.The mechanism needs to carry out additional processing in connector portions, not only increases cost, use is also inconvenient.
Utility model content
In order to solve to divulge information in the prior art, tube connection ports and ventilation blower and air draft pipe connected pipe mouth mismatch use not side
Just technical problem, the utility model provide a kind of reliable ventilation tubular construction easy to connect.
The technical solution of the utility model is：A kind of Multifunctional lampblack machine ventilation tubular construction, it includes body, body end
Pipe joint is connected with, pipe joint connects provided with stepped connecting hole with pipe body hole, and the outer surface of connecting hole hole wall is provided with projection
Blend stop.The stepped connecting hole with ventilation blower and the matching of air draft pipe connected pipe mouth can be selected to be connected with ventilation duct.Without configuration
The ventilation duct of distinct interface caliber, it is cost-effective.It is easy to connect reliable.
Preferably, the bottom hole of connecting hole and hole madial wall are at a right angle；Prevent from connecting when being connected with ventilation blower or exhaust duct
Adapter constantly insertion connecting hole, causes connection hole wall to ftracture, the connecting tube of ventilation blower or exhaust duct is adjacent to connecting hole bottom, is connected
Good airproof performance.
Preferably, pipe joint is provided with internal thread hole, body end is connected by the external screw thread of setting with internal thread hole；Take
It is applied widely with flexible.
Preferably, pipe joint links into an integrated entity with body end；Easily manufactured, installation is simple, cost-effective.
Compared with prior art, the beneficial effects of the utility model are：It can select and ventilation blower and air draft pipe connected pipe
The stepped connecting hole of mouth matching is connected with ventilation duct, easy to use, applied widely.The logical of distinct interface caliber need not be configured
Airduct, it is cost-effective.Simple and reasonable, connection is reliable, good airproof performance.

Pipe joint 2 is provided with internal thread hole 23.The screw thread of internal thread hole 23 is pipe screw thread.Internal thread hole 23 is inserted in the end of body 1, passes through spiral shell
Line connects.The pipe joint 2 connects provided with stepped connecting hole 22 with pipe body hole.The ladder of this specification embodiment connecting hole 22
There are Φ 150mm, Φ 160mm and tri- kinds of Φ 180mm in aperture.The bottom hole of connecting hole 22 and hole madial wall are at a right angle.Ladder aperture Φ
The bottom hole in 150mm holes is connected with internal thread hole 23, and connecting hole 22 connects with pipe body hole.The outer surface of the hole wall of connecting hole 22 is provided with convex
The blend stop 21 risen.Each shoulder hole of connecting hole 22 is at least provided with a blend stop 21.Outer wall of the blend stop 21 along connecting hole 22 one week
Set.The each shoulder hole of this specification embodiment is provided with two blend stops 21, a nose end for being located at each shoulder hole, another position
In the middle part of each shoulder hole lateral wall.
The present embodiment illustrates that the external diameter of connecting tube 3 of lampblack absorber is Φ 160mm by lampblack absorber of ventilation blower.Connecting hole 22
Middle shoulder hole matches with connecting tube 3.The big shoulder hole of the end of connecting hole 22 is removed, such as dotted portion in Fig. 2.Will connection
