Transmission box, required products for broken bridge aluminum. Today I will take you to know the transmission box of Jiandun Hardware.
The drive box is installed on the window or door to lock the door or window. 置过松，轻拨把手即可将门或窗打开。 In use, if the transmission in the transmission box is too loose, the door or window can be opened by lightly turning the handle.

For those who are weak such as children, causing the trouble of opening the door or window, the following technical solutions are provided in the prior art: increase the friction of the transmission. Increase the opening force required for unlocking; or increase the length of the handle to reduce the opening force required for unlocking, and then adjust the corresponding technology so that the opening force required for the door or window lock is suitable for the public, although the opening force is adjusted to Suitable for the needs of most users, but cannot be adjusted freely. In some special cases, such as children's rooms and adults' rooms, the opening forces required are different, and multiple transmission boxes need to be purchased to increase the installation cost.
The upper box body and the lower box body are connected by screws, and the upper box body and the lower box body are provided with slide rails.
