Description

Air door frame mechanism

The invention belongs to the technical field of a damper, in particular to an air door frame mechanism which is simple in structure and does not occupy space, thereby improving the aesthetics of the overall design and reducing the installation cost.

Press, in the supermarket, department store entrances or exits or experimental cabinets and other personnel in and out of the frequent areas, for the convenience of use, the use period is almost closed, but in the era of energy-saving awareness, not closing the door will make the air leaking and outdoor dirty The air ran indoors. In order to block the outflow of cold air in the room, or to avoid outdoor foreign objects (such as mosquitoes, flies, insects, etc.) entering the room, a valve is usually installed above the door frame of the entrance and exit. Usually, the valve system is installed at the top of the door of the building. With the airflow blown down, a gas wall can be formed between the door and the outside of the door. On the one hand, the cold air in the room can be avoided, on the other hand, It can block the dirty air or dust from the outside to enter the room.

However, the valve installed at the top of the door has some problems in practical use. First, in order to generate airflow, the valve is usually provided with a blower inside, and the vibration is large and the noise is large during operation. Secondly, the body of the conventional air door is mostly composed of iron plate welding, the weight is very heavy, the handling is not easy, and the inconvenience of installation and maintenance usually requires two talents to be installed smoothly. Again. A cover is additionally provided inside the valve body, and the cover is disposed outside the fan to form a air duct for The air flow is guided, which makes the construction more complicated and causes inconvenience in assembly. Even if it is added, it will stand out in the door frame, affecting the use and design of the overall space, resulting in an unsightly phenomenon.

In other words, the current method of setting the valve above the door frame does not meet the needs of actual use. However, there are problems such as complicated structure, large size, difficult installation, unsightly and loud noise. Therefore, how to solve the above problems is the industry. important topic.

In view of this, the inventors have in-depth discussions on the problems faced by the existing external valves, and actively pursued solutions through years of experience in R&D and manufacturing of related industries, and have been successfully developed through continuous efforts in research and trials. An air door frame mechanism is provided to solve the inconvenience and trouble caused by the installation of the valve door of the existing door frame.

Therefore, the present invention mainly provides an air door frame mechanism having a simple structure, thereby simplifying parts and achieving ease of manufacture and assembly, and effectively reducing the cost thereof.

In addition, the present invention is mainly to provide a space-saving air door frame mechanism, which can connect the remote air blower through the pipeline, so that the overall appearance of the door frame is consistent, and the space can be utilized to effectively improve the appearance thereof.

Based on the above, the present invention mainly achieves the foregoing objects and effects by the following technical means, which is composed of a frame body having two side rods on both sides of the frame body, and the top ends of the rods are erected at the same time. The utility model has a beam bar, and the space between the side bar of the frame body and the beam bar forms an entry and exit space; and the beam of the frame body is formed with at least one side bar extending along the two ends. One of the two ends of each air guiding channel is provided with an air inlet for introducing external high-pressure air into the air guiding channel of the frame, and the other beam bar is formed with at least one air outlet at the corresponding access space of each air guiding channel for providing Form a top-down air curtain in the access space.

Therefore, the air curtain frame mechanism of the present invention can utilize the air guiding channel and the air outlet formed in the beam of the frame beam to form an air curtain in the space in and out of the frame body to achieve the purpose of blocking gas circulation. At the same time, since the blower is installed at the far end, vibration is not formed on the frame, the noise can be effectively reduced, and the overall structure is extremely simple, and can be installed together in the design of the building, without the need of a routine. With the addition of blowers, it will not protrude from the door frame, nor will it affect the use and design of the overall space, which will enhance the overall aesthetics, and further increase its added value and increase its economic benefits.
