Realize the conversion of interface type and size, and lead to not wind speed is carried out speed and Flow-rate adjustment, single function and use model
Enclose little.
Utility model content
The purpose of this utility model is to solve the adapter of existing bendable when being applied to corrugated tube and being docked, wind
Trouble installed by pipe, and dismounting is inconvenient and easily leaks air, and has had a strong impact on the convenience of airduct installation and asking of work efficiency
Topic, provides that a kind of structure is simple, easy to use, installation effectiveness is high and the ventilation shaft adapter of the adjustable bendable of flow.
The purpose of this utility model can employ the following technical solutions to reach：
A kind of ventilation shaft adapter of bendable, including connector body and inserted sheet, described connector body is hollow
Structure, described connector body is provided with entrance and exit, and the entrance and exit of described connector body is respectively oval and circle
Shape structure；Described connector body is bending structure, and the inwall of described connector body is provided with outwardly and is used for adjusting
The regulation chamber of air flow rate, described regulation chamber is provided with the retaining wall vertical with air current flow direction；Described connector body
Arrival end has groove, and one end plug-in mounting of described inserted sheet enters in described groove, and this end plug-in mounting enters the outer wall of oval corrugated tube
In wave groove, oval bellows-sheathed is in the entrance of adapter.
As a kind of preferred scheme, the sectional area of the entrance of described connector body is more than the section of the outlet of adapter
Long-pending.
Further, described inserted sheet is U-shape structure, and the two ends plug-in mounting of the U-shaped opening of described inserted sheet enters in described groove, and
Plug-in mounting enters in the outer wall wave groove of oval corrugated tube.
As a kind of preferred scheme, described connector body is high density polyethylene (HDPE).
As a kind of preferred scheme, described connector body passes through blow molding.
Implement this utility model, have the advantages that：
1st, this utility model when mounted, will be sheathed on outside circle corrugated pipe in the outlet of connector body and passes through clip
Carry out locking to install, and oval corrugated tube plug-in mounting entered the entrance of connector body, and one end of inserted sheet is inserted in groove,
And so that this end plug-in mounting is entered in the outer wall wave groove of oval corrugated tube, then under the positioning action of inserted sheet, corrugated tube is in adapter
The direction of motion of the central axis of body is restrained, so that oval corrugated tube is fixedly installed on connector body,
The oval corrugated tube of realization is docked with circle corrugated pipe, easy for installation, quick and efficiency high.In dismounting it is only necessary to pull out
After inserted sheet, oval corrugated tube is extracted and can be quickly and easily disassembled down along the central axial direction extroversion of connector body
Come, decrease the labor intensity of workman, improve the efficiency of installation and removal, shorten construction period.
2nd, during air-flow enters flow direction outlet from the entrance of connector body, fraction is in stream for this utility model
During adjusted chamber, by the retaining wall vertical with air current flow direction stop and reverse flow is so that going out from connector body
The speed of the air-flow that mouth flows out reduces, and because the sectional area of the entrance of described connector body is more than the outlet of adapter
Sectional area, so that the air flow rate from the outlet outflow of connector body is less than the flow of its entrance, realizes air flow rate
The purpose adjusting.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Embodiment
Referring to Fig. 2 and Fig. 4, the present embodiment is related to the ventilation shaft adapter of bendable, including connector body 1 and inserted sheet
2, described connector body 1 is hollow structure, and described connector body 1 is provided with entrance 11 and outlet 12, described connector body 1
