However, in order to block outdoor dust, rainwater or birds, the negative pressure side air window is closed in a normal state and is opened when air is exhausted and exchanged, and meanwhile, the opening size of the blades needs to be adjusted according to the size of air flow.
At present, the opening and closing of a plurality of negative pressure side air windows need to be manually adjusted and fixed one by an operator, and time and labor are consumed; the opening and closing of the side air windows are controlled by an electric or pneumatic mechanical device, and the opening sizes of all the air windows are the same due to the adoption of mechanical control, and the electric or pneumatic device needs daily maintenance and consumes more electric energy. .
Disclosure of Invention
Therefore, the utility model aims to provide a negative pressure side air window opening and closing regulation and control device which is simple in structure, simple and convenient to operate, free of mechanical devices, good in regulation and control stability and capable of ensuring the opening and closing effect of a side air window.
In order to solve the technical problem, the utility model provides a negative pressure side wind window opening and closing regulation and control device which comprises a handle, wherein connecting arms are arranged on two sides of the handle, the end parts of the connecting arms are rotatably connected with a fixed seat arranged on a wind window blade, and the fixed seat is provided with a locking unit used for the end parts of the connecting arms so as to realize the rotation and locking of the handle.
The size of opening and closing and opening of the blades can be automatically adjusted according to the size of airflow thrust received by the blades under different airflow conditions through the change of the included angle between the rotation of the handle and the blades of the air window.
Furthermore, the locking unit is of a spring ratchet structure.
Furthermore, the locking unit is an eccentric shaft locking structure.
Furthermore, the locking unit is of an expansion screw structure.
The utility model has the following beneficial effects: the regulating and controlling device is simple in structure, simple and convenient to operate, free of mechanical devices, good in regulating and controlling stability and capable of guaranteeing the opening and closing effect of the side air window.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1: the wind window blade locking device comprises a handle, connecting arms are arranged on two sides of the handle, the end portions of the connecting arms are rotatably connected with fixing seats installed on wind window blades, and the fixing seats are provided with locking units used for the end portions of the connecting arms, so that the rotation and locking of the handle are realized.
Wherein:
the end part of the connecting arm of the handle can rotate after the fixed seat is connected, so that the handle is driven to rotate around the wind window blade, and the rotating track of the handle is an arc taking the horizontal direction of the fixed seat on the wind window blade as an axis and the connecting arm as a rotating radius. According to the lever principle, the fixed seat on the wind window blade is used as a fulcrum, the self weight of the handle and the corresponding moment formed by the rotation of the handle to different included angles with the blade can balance the moment formed by the self weight and airflow of the wind window blade on the other side of the fulcrum to the blade pushing force.
When the exhaust and air exchange are not needed, the thrust of the airflow acting on the blades is zero, and the blades cannot be opened and are in a closed state only by the self weight; when the air flow is not high, the thrust of smaller air flow acting on the blades is smaller, and the opening of the wind window blades is smaller; when the air flow is high, the thrust of the larger air flow on the blades is also larger, and therefore the opening of the louver blades becomes larger.
Furthermore, the locking unit is of a spring ratchet structure, and the structure can realize locking and releasing of the end part of the connecting arm of the adjusting handle through the matching of a ratchet and a spring;
furthermore, the locking unit is an eccentric shaft locking structure which can be locked and unlocked through an eccentric shaft, so that the end part of the connecting arm of the adjusting handle is locked and released;
furthermore, the locking unit is of an expansion screw structure, and the structure can be screwed and loosened through the expansion screw to lock and release the end part of the connecting arm of the adjusting handle.
The locking unit adopts a plurality of structures, and has good locking effect, so that the handle can be ensured not to be loosened after being locked at a required position, and the stability of regulation and control is ensured.
In addition, the air flow size of the side air windows at different installation positions possibly varies due to the influence of factors such as indoor area and structure, the number and positions of the fan and the side air windows, and the like, and at the moment, the included angle between the handle and the blade of the corresponding side sealing window regulating and controlling device can be adjusted individually according to actual air flow conditions, so that the balanced flow of air is realized, and the efficiency and the effect of exhaust and ventilation are improved.
The foregoing is a more detailed description of the utility model in connection with specific preferred embodiments and it is not intended that the utility model be limited to these specific details. For those skilled in the art to which the utility model pertains, several simple deductions or substitutions can be made without departing from the spirit of the utility model, and all shall be considered as belonging to the protection scope of the utility model.
