Description

Can switch pair air port

Technical field

The utility model relates to a kind of air exchange pipe assembly, and that is especially located at pipe ends can switch pair air port.

Background technology

In the air draft pipeline or central air-conditioning pipeline of indoor, be generally provided with air grille in the end of pipeline, for semiclosed pipe ends, play auto levelizer and logical wind action.

Can switch pair air port be one wherein, generally vertically be installed on body of wall, blade is downward-sloping to prevent rainwater from entering, in use, especially when exhaust uses, along with air-flow can bring into a large amount of dirt entrapment on blade or admission passage inner, and due to blade be oblique curved surface or plane, in order to ensure the usual of gas channel, angle between blade and plane is larger, the direct admission passage of air is inner, long term accumulation can affect ventilation quality and air quality, comparatively difficult when cleaning after in dust admission passage, maintenance for equipment brings larger inconvenience.

Utility model content

The utility model provides a kind of minimizing in passage to accumulate dust, and easy cleaned can switch pair air port.

To achieve these goals, the utility model adopts following technical scheme:

What comprise that a frame and multirow be installed on frame inside can the blade of folding, described blade connects the rocking bar that controls blade folding, described blade is along the oblique setting of airflow direction, its improvement is: the third gear sheet that described blade comprises the first catch be fixed on frame, the second catch connected with the first catch and connects with the second catch, and the first described catch, the second catch and third gear sheet are successively in 175 ° of knuckles.

Preferably, the first described catch becomes 15 degree of angles to fix with frame place plane.

Preferably, the second described catch and the first catch are in+175 ° of angles.

Preferably, described third gear sheet becomes ± 175 ° of angles with the second catch.

Preferably, the first described catch, the second catch and third gear sheet are integral type structure, and the first catch, angle between the second catch and third gear sheet are bent to form by same sheet material.

Preferably, described frame is square.

Owing to have employed said structure, of the present utility model can switch pair air port at air when entering blower interior, through multiple catch, dust is adsorbed successively, air flow is changed by the multistage catch angularly arranged, expand adsorption area, and grid is multistage laminated structure, can be removed the backhaul of surface attachment by simple wiping, cleaning and attended operation also significantly simplify, and make the operation of equipment more efficient.

Detailed description of the invention

As depicted in figs. 1 and 2, the utility model embodiment can switch pair air port comprise that a frame 1 and multirow be installed on frame inside can the blade 2 of folding, described blade 2 connects the rocking bar 3 of a control blade folding, described blade 2 is along the oblique setting of airflow direction, the third gear sheet 6 that described blade 2 comprises the first catch 4 be fixed on frame, the second catch 5 connected with the first catch 4 and connects with the second catch 5, the first described catch 4, second catch 5 and third gear sheet 6 are successively in 175 ° of knuckles.

In the present embodiment, the first described catch 4 becomes 15 degree of angles to fix with frame 1 place plane.

In the present embodiment, the second described catch 5 and the first catch 4 are in+175 ° of angles.

In the present embodiment, described third gear sheet 6 and the second catch 5 one-tenth ± 175 ° angle.

In the present embodiment, the first described catch 4, second catch 5 and third gear sheet 6 are integral type structure, and the angle between the first catch 4, second catch 5 and third gear sheet 6 is bent to form by same sheet material.

In the present embodiment, described frame 1 is square.

The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
