First, appearance should be beautiful:
The surface paint of wooden doors and windows shall be smooth and bright, free of quality defects such as falling, bubbles, wrinkles, etc., and there shall be no corrosion points, dead ends, and broken residues; the wood and the color of door and window covers shall be coordinated with the color of doors and windows, and the panel shall be The color difference of wood lines cannot be large, and the tree species should be the same.
Second, the door and window fan Founder, can not warp and deform, the door and window fan just can be stuffed into the door and window frame, and in line with the door and window frame:
If the gap between the sash and the frame is large, it is mainly due to the inaccessibility of the installation or the fact that the frame of the door and window is not perpendicular to the ground. The sash can be removed and re-planned; if the frame of the door or window is not vertical, the gasket should be found within the frame. straight.
Third, the hinge should be accurate and securely installed:
If the hinge is not on the right side, it will cause the door and window fan to not match the frame, and the door and window switch will not be smooth. Each hinge can be unscrewed by one screw, and then the fit of the door and window fan and the frame can be adjusted. After the adjustment is correct, all screws are tightened. If the hinge screws are short, or if they are screwed in, the screws are not screwed or the screws are skewed, it will cause the door sash to wander. The appropriate screws should be replaced. The screws must be straight. The screws should be pinned in 1/3 and the rest of the screws must be screwed in.
4. The opening and locking of the door lock shall be smooth, and the two parts locked on the door leaf and the door frame shall be matched:
Inappropriate locks can cause the door switch to be uncomfortable. The tongue plate should be removed, the tongue and groove should be repaired with a chisel, and the position of the tongue and bolt mouth should be adjusted before installation. In addition, the opening direction of the door must meet the requirements.
Fifth, there must be grass-roots materials in the door and window cover:
When the window cover is made of block board or density board, the base board should be fixed on the keel of the window frame base and then nailed; the door cover should be made of wood and then framed, planed and straightened, and then assembled and installed on the wall. On the body, cover the base plate and veneer again. Tap the side panel of the door and window cover by hand. If a sound of empty drums is heard, it means that there is no padding such as a blockboard, etc., which should be dismantled.

A photo cell, also known as a photocell or light-sensitive resistor, is an electronic device that detects and measures light levels. It is commonly used in various applications such as automatic lighting systems, security systems, and photography equipment.
The main advantage of a photo cell is its ability to automatically respond to changes in light intensity. When exposed to light, the resistance of the photo cell decreases, allowing current to flow through it. Conversely, in the absence of light, the resistance increases, restricting the flow of current. This property makes photo cells highly efficient in controlling lighting systems, as they can automatically switch lights on or off based on the surrounding light conditions.
Another advantage of photo cells is their reliability and durability. They are designed to withstand harsh environmental conditions and can operate effectively for long periods of time without requiring maintenance. Additionally, photo cells have a fast response time, allowing them to quickly adjust to changes in light levels.
Furthermore, photo cells offer energy-saving benefits. By automatically controlling the lighting system, they can reduce unnecessary energy consumption by ensuring that lights are only used when needed. This not only helps to lower electricity bills but also contributes to environmental sustainability.
In conclusion, photo cells are versatile devices that provide a convenient and efficient solution for light detection and measurement. Their automatic response to light changes, reliability, and energy-saving capabilities make them a popular choice in various industries.
