As further describing for above-mentioned technical proposal：

The top of the sunpender and the end of limiting card are arcuate structure design.

As further describing for above-mentioned technical proposal：

The outer end of the limiting card is fixedly connected by fixed block with draw ring.

As further describing for above-mentioned technical proposal：

The inside of the fixing card offers through-hole, and the internal diameter of through-hole is equal with the diameter of sunpender.

As further describing for above-mentioned technical proposal：

The aperture of the limit hole is equal with the diameter of limiting card.

In the utility model, first, by the deflector being placed equidistant with inside HVAC pipe, the heating of circulation can be carried out Water conservancy diversion reduces its turbulent flow so that flow direction of the heating in HVAC pipe is gentle and consistent, warm so as to effectively reduce The noise that air-flow passband comes, this is simple in structure, and noise reduction is shown, and convenient for promoting, secondly, can be carried out HVAC pipe by anchor ear It is fixed, and the limit hole by being opened up at the top of sunpender can directly engage with fixing card, by pulling draw ring, limiting card can be with hanging Limit hole on bar is detached from, you can is easily removed HVAC pipe, by this fixed structure, the extension of HVAC pipe can be convenient for hang Installation and detachable maintaining, effectively reduce working strength.

Specific embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole Embodiment.

With reference to Fig. 1-3, a kind of engineering HVAC pipe for having noise elimination function, including HVAC tube body 1, fixing card 6 and deflector 7, the inside of HVAC tube body 1 has been placed equidistant with deflector 7, and the outside of HVAC tube body 1 has been placed equidistant with anchor ear 2, the top of anchor ear 2 Sunpender 3 is fixedly connected with, the top of sunpender 3 is fixedly connected, and limit hole 4 is opened in sunpender 3 by limit hole 4 with fixing card 6 Top both sides, the internal symmetry of fixing card 6 is provided with limiting card 61, limiting plate is provided with outside the side of limiting card 61, and Limiting plate is by being set in the inner wall elastic connection of resetting spring 62 and fixing card 6 outside limiting card 61, the top of fixing card 6 Middle position is vertically welded with dilating screw 5.

The top of sunpender 3 and the end of limiting card 61 are arcuate structure design, and the outer end of limiting card 61 passes through fixation Block is fixedly connected with draw ring 63, and the inside of fixing card 6 offers through-hole, and the internal diameter of through-hole is equal with the diameter of sunpender 3, The aperture of limit hole 4 is equal with the diameter of limiting card 61.

The radii fixus of anchor ear 2 is indefinite, as the diameter of HVAC tube body 1 corresponds to pairing setting, the top of sunpender 3 Portion and the end of limiting card 61 are designed to arcuate structure, can easily engage with limiting card 61 convenient for sunpender 3 in this way, the HVAC The deflector 7 being placed equidistant with inside pipe is the turbulent flow for reducing circulated gases, so as to achieve the purpose that noise reduction, and deflector 7 not have setting in entire HVAC pipe, but multigroup deflector 7 is spaced certain wait and sets one group over long distances, so as to reduce The quality of HVAC pipe, top and the floor carrier of dilating screw 5 are directly fixedly connected.

Operation principle：Fixing card 6 is fixedly connected by dilating screw 5 with floor carrier in use, existing, then by anchor ear 2 It is fixed, then the top of sunpender 3 is inserted into fixing card 6, when limit hole 4 and the position of limiting card 61 are in HVAC pipe When on same level straight line, acted in the elastic force of resetting spring 62, two limiting cards 61 can be inserted into the inside of limit hole 4, in this way Just light hang for completing HVAC pipe hangs work, when needing to remove HVAC pipe, by pulling draw ring 63 that can be easily accomplished HVAC pipe is removed, and turbulent flow can effectively be reduced under the action of deflector 7 by being passed through the heating inside HVAC pipe so that warm Flow of air direction is gentle and consistent, so as to achieve the purpose that effective noise reduction.
