Description

Technical Field

[0001] This utility model relates to the field of keel connection technology, and in particular to an adjustable louver system. Background Technology

[0002] According to market research and surveys, the return air louvers currently used in the market have the following shortcomings in structural design, installation, and maintenance:

[0003] 1. In the market, louvers are basically divided into two types: one is adjustable air volume, and the other is a louver product with a preliminary filter screen that is not integrated together.

[0004] 2. According to the requirements of cleanrooms, there are no products on the market that can have both filtration and regulation functions and can be integrated with the structure of the system itself.

[0005] 3. The materials and structure of the louvers used in the market are quite simple and do not meet the requirements of cleanroom air volume and air pressure.

[0006] 4. Installation and maintenance are inconvenient. The louvers are usually fixed with spring screws or similar methods, which is very inconvenient for cleanrooms that operate for a long time.

[0007] Therefore, designing an adjustable louver system that integrates filtration and airflow regulation and can be quickly assembled has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] In view of the shortcomings or deficiencies of the prior art, the technical problem to be solved by this utility model is to provide an adjustable louver system.

[0014] Furthermore, both ends of the slide rail are provided with limiting blocks. When the slider slides to the limiting blocks at both ends, the filter fixing frame is in the maximum open position or in the closed position.

[0015] Furthermore, the filter fixing frame is provided with a U-shaped mounting groove, and a filter screen structure is snapped into the U-shaped mounting groove.

[0016] Furthermore, the filter structure includes: a first layer of filter and a second layer of filter, wherein the first layer of filter is snapped into the U-shaped mounting groove, and the second layer of filter is laid on the first layer of filter.

Then, the louvers are inserted into the floor track 2 and the edge trim. The buckle 51 and the pressure strip 52 are fixed to the connection of the edge keel 6 by screws 54, which helps to clamp the wall panel and the louvers. By continuously installing in this way, groups of louvers and louvers are assembled to complete the installation of the entire system. The return air louver structure includes: a louver shell, a filter fixing frame 8, and louver blades 4. The filter fixing frame 8 is installed inside the louver shell.

The filter structure is integrally formed, ensuring structural strength while facilitating cleaning and replacement.

[0036] Furthermore, in this embodiment, the two ends of the louver blade 4 are provided with through holes, and a rotating shaft is installed in the through holes. Adjacent louver blades 4 are connected end to end by the rotating shaft and installed in the inner frame 32.
