For this reason, this application has designed an asymmetric balanced non-pressure air door to solve above-mentioned problem.
Disclosure of Invention
The utility model discloses a remedy prior art wind door close the back if the wind pressure can leak out not enough easily greatly, provide an asymmetric balanced non-pressure air door.
The utility model discloses a realize through following technical scheme:
the utility model provides an asymmetric balanced non-pressure air door, includes door leaf and link gear, its characterized in that:
the door leaf comprises a forward door leaf and a reverse door leaf which are hinged to open and close, and the width of the forward door leaf is larger than that of the reverse door leaf;
the linkage mechanism is arranged on one side above the forward door leaf and the reverse door leaf.
Further, for better realization the utility model discloses, the link gear includes turning arm, connecting rod and straight arm.
Further, for better realization the utility model discloses, the connecting block of connecting lever for being the L type, the perpendicular fixed connection of one end at the positive top of reverse door leaf of connecting lever, the one end of the articulated connecting rod of the other end, the one end of the articulated straight arm of the other end of connecting rod, the perpendicular fixed connection of the other end of straight arm is at the positive top of forward door leaf.
The utility model has the advantages that:
the utility model discloses a forward door leaf area is greater than reverse door leaf, and when the air door closed condition, the pressure that forward door leaf received is big than reverse door leaf, can be taut with reverse air door, has solved the reverse door leaf of part air door installation place and has received the wind pressure and close not tight problem.

In the description of the present invention, it should be noted that the terms "middle", "upper", "lower", "horizontal", "inner", "outer", etc. indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship which the product of the present invention is usually placed in when in use, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used merely to distinguish one description from another, and are not to be construed as indicating or implying relative importance.
Furthermore, the terms "horizontal", "vertical" and the like do not imply that the components are required to be absolutely horizontal or pendant, but rather may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected. Either mechanically or electrically. They may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Fig. 1-3 are a specific embodiment of the present invention, which is an asymmetric balanced non-pressure air door, in this embodiment, one air door is designed to have two different width door leaves, a narrower reverse door leaf 2 and a wider forward door leaf 1, and a linkage mechanism is installed on one side of the upper part of the forward door leaf 1 and the reverse door leaf 2. The link gear includes connecting lever 3, connecting rod 4 and straight arm 5, and connecting lever 3 is the connecting block that is the L type, and the perpendicular fixed connection of one end of connecting lever 3 is at the positive top of reverse door leaf 2, and the one end of the articulated connecting rod 4 of the other end, the articulated one end of straight arm 5 of the other end of connecting rod 4, and the perpendicular fixed connection of the other end of straight arm 5 is at the positive top of forward door leaf 1.
The air door of this embodiment is by during the open mode gets into closed condition, the wind pressure is used in on forward door leaf 1, close the air door, this moment because the area of contact of forward door leaf 1 is big, the pressure ratio of the wind that receives is big than reverse door leaf 2, so can be taut reverse door leaf 2, the problem that reverse door leaf 2 of having solved partial air door installation place pressed to wind and closed not tight is solved, through the mounted position of adjustment turning arm 3 and straight arm 5, realize moment balance, avoid arousing connecting rod 4 long-term pressurized appearance to warp.
