Description

Double-layer shutter structure

The invention relates to a double-layer blind structure, which is mainly to improve the conventional single-layer blinds with poor airtightness effect, etc. Through the design of the blade base plate, it can be combined with inner and outer double-layer blinds At the same time, the opening and closing functions are controlled, and the stop ribs on the inner and outer edges of the window frame are used to cover and seal the gap between the two ends of the blade and the window frame, which can greatly improve the overall airtight performance.

In general, in order to avoid the sun, strong winds, rain and other weather conditions, usually add blinds, especially to prevent the damage caused by the typhoon, and also have anti-theft function, and also design metal blinds, use Its metal material cooperates with the control linkage mechanism, giving its shutters better airtightness and sturdiness in use.

The above-mentioned conventional blinds are mainly designed with a single-layer blade in the structural design. After the blade substrates arranged at the two ends of each blade are pivotally assembled with the window frame, the blades are connected by the connecting rod pivot group The pivot arm extended by the board substrate can be linked to the opening and closing of the body of each blade, so that the angle rotation of each blade can be easily completed by the adjustment knob provided on the side of the window frame to reach the shutter Control of opening and closing.

However, the aforementioned shutters, because the blades are only designed as a single layer, and the precision of its assembly is not high, so when it is closed, its airtightness effect is very poor, and it cannot effectively prevent the intrusion of external airflow. There is a gap between the two ends of the blades and the window frame, which makes it impossible to effectively block the strong wind intrusion, and even cause roaring noise. Even when it rains, it is easy to get rain from The problem of seepage there, it is necessary to try to solve the improvement.

In view of the problems that the single-layer blades of the existing shutters generally have poor airtightness and that there are easy gaps between the two ends of the blades and the window frame, the inventors specially conducted research and improvement based on their years of experience in related industries and Technology, and further developed the double-layer shutter structure of the present invention.

The structural design of the double-layer louver of the present invention mainly adopts the H-type blade board as the assembly and connection interface of the inner and outer layer blades, and makes the connecting groove frames on both sides of the blade boards move up and down. Type, and a pivot arm is formed on the inner edge side of the inner connecting groove frame, and the pivot hole set on the middle base plate of the blade base plate is pivotally set on the window frame, and the blades are pivotally connected with the linkage rods The pivot arm of the substrate achieves an integrated linkage relationship to control the simultaneous opening and closing and angle adjustment of the inner and outer double-layer blades, and a pair of micro-convex parts are formed on the inner and outer edges of the window frame A stop groove is formed between each pair of stop ribs to embed brush strips, and when the inner and outer double-layer leaf plates are closed, the two ends of the sealing leaf filler plate and the window frame are blocked The possible clearance space, according to which the excellent airtight effect is obtained.

The double louver structure of the present invention allows the inner and outer double louver to be assembled through the planning of its lamella substrate, and gives the simultaneous opening and closing control function, so that it can operate without affecting its operating habits. Through the double-layer blades, the double isolation is formed to give a better airtight effect, and the stop ribs on the inner and outer edges of the window frame cover and seal the gap between the two ends of the blade and the window frame. Greatly improve its airtight effect, effectively solve the problems and defects of the conventional single-layer blinds.
