Description

A hollow electric louver Technical Field

[0001] This utility model relates to the field of louvered fan technology, and in particular to a hollow electric louvered window. Background Technology

[0002] Venetian blinds are a type of window that can be used to block sunlight, prevent dust from entering the room, and also block ultraviolet rays and protect privacy. Glass Venetian blinds refer to blinds placed inside a window sash with double-glazed glass, thereby achieving sun shading while reducing the floor space occupied by the blinds and ensuring the stability of the blinds in use.

[0003] The aforementioned louver structure has its blades fixed inside the glass. When maintenance of the blades is required, the glass needs to be removed, which is quite cumbersome. An improvement is needed to design a hollow louver structure that is easier to maintain. Summary of the Invention

[0004] The purpose of this invention is to provide a hollow electric louver to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hollow electric louver, comprising an outer frame, glass components, an inner frame, and a push block. The inner frame is installed inside the outer frame. Multiple bearing seats are provided on one side of the inner frame, and a rotating rod is installed inside each bearing seat. One end of the rotating rod is connected to a fan blade, and the other end is connected to a worm gear. A transmission groove is formed on one side of the inner frame, and the worm gear is placed inside the transmission groove. A rotating rod is movably arranged inside the transmission groove. Multiple hollow worm gears are sleeved on the outside of the rotating rod, and the hollow worm gears mesh with the worm gear. A motor drives the entire rotating rod to rotate, thereby rotating the multiple hollow worm gears on the rotating rod. The hollow worm gears mesh with the worm gear, thereby driving the worm gear to rotate. The worm gear is coaxial with the fan blade, thus driving the fan blade to rotate, thereby controlling the opening and closing of the fan blade and realizing the opening and closing of the louver.

[0006] Preferably, the outer frame has push grooves on both the top and bottom sides, and push blocks are movably disposed inside the push grooves.

[0007] Preferably, a baffle is provided on the inner side of the push block, and a locking screw is threadedly connected to the outer side of the push block.

[0008] Preferably, locking support plates are provided at the top and bottom of the transmission inner groove, and locking holes are provided inside the locking support plates, with one end of the locking screw threaded into the locking hole.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] This application features a removable inner frame structure within the outer frame, with multiple fan blades housed within the inner frame. When maintenance of the fan blades is required, rotating the locking screw releases the inner frame, pushing the push block inside the push groove, causing the locking support plate to disengage from the baffle. The inner frame loses its restraint and can be directly pulled out laterally from within the outer frame, thus exposing the fan blades and facilitating inspection and maintenance of the fan blades inside the inner frame.
