Abstract
The utility model discloses a kind of novel air channel structures, including ventilation duct, the both ends of the ventilation duct are respectively the outlet air end of the air intake that air feed enters and air feed discharge, are provided with the necking mechanism for reducing outlet air port caliber size at the outlet air port of the outlet air end, the necking mechanism includes：Multiple arcs piece hingedly coordinates with ventilation inside pipe wall respectively, and is arranged circumferentially along ventilation inside pipe wall；Support ring is set in ventilation duct and can be engaged with the outer wall of arc-like sheet；Clamping screw, for support ring to be fixed on ventilation inside pipe wall；Multiple location holes passed through for clamping screw are offered on the ventilation duct, multiple location holes are along the axial arranged of ventilation duct.When needing to reduce out wind velocity, the size of the bore of outlet air port can be adjusted by necking mechanism so that the bore of outlet air port reduces, and to reduce the bore of outlet air port, and then slows down and wind velocity.
Description
Technical field
The utility model belongs to technical field of mechanical processing, and in particular to a kind of novel air channel structure.
Background technology
In the processing of existing kinds of processes, installation ventilation duct is needed to be aerated, the air outlet of existing ventilation duct
Caliber size cannot adjust mostly, thus cause outlet air size that cannot be adjusted by the outlet air bore of ventilation duct.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of novel air channel structure, can adjust ventilation duct
Outlet air caliber size.
The technical solution of the utility model is：A kind of novel air channel structure, including ventilation duct, the both ends of the ventilation duct
The outlet air end of air intake and air feed discharge that respectively air feed enters, is provided with diminution outlet air at the outlet air port of the outlet air end
The necking mechanism of port caliber size, the necking mechanism include：
Multiple arcs piece hingedly coordinates with ventilation inside pipe wall respectively, and is arranged circumferentially along ventilation inside pipe wall；
Support ring is set in ventilation duct and can be engaged with the outer wall of arc-like sheet；
Clamping screw, for support ring to be fixed on ventilation inside pipe wall；
Offer multiple location holes passed through for clamping screw on the ventilation duct, multiple location holes along ventilation duct axis
To arrangement.
Preferably, being engaged between adjacent arc-like sheet.
Support ring falls off in order to prevent, preferably, being provided with reset bullet between the support ring and the outer wall of arc-like sheet
Spring.Even if do not locked by clamping screw, under the action of resetting spring so that support ring remains attached to outlet air port
Place, avoids the loss of component.
Preferably, the arc-like sheet is 3~6.
Preferably, the arc-like sheet is 4.
Compared with prior art, the beneficial effects of the utility model are embodied in：
When needing to reduce out wind velocity, the size of the bore of outlet air port can be adjusted by necking mechanism, it, will when adjusting
Arc-like sheet is rotated around articulated shaft, is then moved up support ring, is then locked by clamping screw, since support ring moves up,
Therefore under the supporting role of support ring so that the bore that arc-like sheet surrounds reduces, so that the bore of outlet air port reduces,
To reduce the bore of outlet air port, and then slows down and wind velocity.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
As shown in Figure 1, the utility model includes ventilation duct 1, the both ends of the ventilation duct 1 are respectively the air inlet that air feed enters
The outlet air end 12 of 11 and air feed discharge is held, is provided at the outlet air port of the outlet air end 12 and reduces outlet air port caliber size
Necking mechanism 2, the necking mechanism 2 include：
Multiple arcs piece 21 hingedly coordinates with 1 inner wall of ventilation duct respectively, and along the circumferentially uniform cloth of 1 inner wall of ventilation duct
It sets；
Support ring 22 is set in ventilation duct 1 and can be engaged with the outer wall of arc-like sheet 21；
Clamping screw 23, for support ring 22 to be fixed on 1 inner wall of ventilation duct；
Multiple location holes passed through for clamping screw 23 are offered on the ventilation duct 1, multiple location holes are along ventilation duct
It is axial arranged.Under normal circumstances, it is engaged between adjacent arc-like sheet 21, the arc-like sheet 21 is 3~6, preferably
Four.
When needing to reduce out wind velocity, the size of the bore of outlet air port can be adjusted by necking mechanism 2, when adjusting,
Arc-like sheet 21 is rotated around articulated shaft, then support ring 22 is moved up, is then locked by clamping screw, due to support ring
22 move up, therefore under the supporting role of support ring 22 so that the bore that arc-like sheet 21 surrounds reduces, so that outlet air port
Bore reduce, to reduce the bore of outlet air port, and then slow down and wind velocity.
Support ring 22 falls off in order to prevent, and resetting spring is provided between support ring 22 and the outer wall of arc-like sheet 21 (in figure
It is not drawn into).Even if do not locked by clamping screw 23, under the action of resetting spring so that support ring remains attached to out
At wind port, the loss of component is avoided.
