The time delay relay KT is installed on the left side of the cover plate 3.

Working principle (take the installation on the sliding window as an example)

As shown in Figures 1, 7, and 8, 37 in the figure is the inner sash frame, 38 is the outer sash frame, and the distance between the inner and outer sash frames is S, and S is greater than the height h of the right shoulder 25. After installation and adjustment, the outer edge glue The sleeve 8 reliably contacts the inner side of the outer sash frame 38 under a certain pressure.

After turning on the power switch K, the control circuit is on standby:

1. The outer or inner sash is pushed in the horizontal direction of the window slideway, and the relay action produces left and right displacement, and the outer edge rubber sleeve 8 rotates together with the roller 9, and then drives the small gear 10 and the large gear 15 to rotate, thereby starting the micro Actuate switch 17 and connect circuit, buzzer 20 reports to the police immediately and delays time automatically.

2. The outer sash is pressed inward, causing the outer edge rubber sleeve 8 and the roller 9 to drive the main shaft 7 and the inner cylinder 4 to be pressed inward, and the axial sliding to the left occurs, so that the spring 6 is compressed, resulting in The fixed-point connector 28 of the two-position contact travel switch on the left base plate 5 moves to the left, so that the right fixed point 30 on it contacts with the moving point 29 and connects the circuit, and the buzzer 20 reports to the police immediately and automatically delays. hour.

The outer sash is pulled outwards or the inner sash is pressed from the outside to the inside, causing the outer edge rubber sleeve 8 and the roller 9 to release pressure, so that the spring 6 is stretched, thereby causing the inner cylinder 4 to slide axially to the right, resulting in a double position. The fixed-point contact body 28 of the contact travel switch moves to the right, so that the left fixed point 30 on it contacts with the moving point 29 and connects the circuit, and the buzzer 20 reports to the police immediately and automatically delays time.

Therefore, from the perspective of anti-theft, as long as the doors and windows are moved, the alarm can be called.
