The working principle of the anti-theft retractable pull box

Anti-theft retractable pull box is a device commonly used in anti-theft alarm systems. It is mainly used to prevent items from being stolen or illegally disassembled. It is usually installed on items or equipment that need to be protected. Its working principle is based on the cooperation of the retractable pull wire and the anti-theft alarm system. The following is the working principle of the anti-theft retractable pull box:

1. The anti-theft retractable pull box contains a thin pull wire, which is usually made of elastic material and can be retracted within a certain range. One end of the pull wire is usually connected to the item or equipment, and the other end is connected to the sensor or trigger in the pull box.

2. When the anti-theft device is in normal state, the pull wire maintains a certain tension and will not be broken. At this time, the item is in a safe state.

3. When the thief tries to disassemble or pull the protected item, the pull wire of the anti-theft retractable pull box will be stretched or broken. The change of this pull wire will trigger the internal sensor or switch.

4. The breakage or elongation of the pull wire will cause the sensor in the pull wire box to sense the change, and then trigger the alarm signal through the connected alarm system, warning the owner or security manager that the item may be stolen or being moved.

5. In some designs, the anti-theft retractable pull box has a self-recovery function. That is, when the item is restored to its normal position, the sensor in the pull wire box will reset and the system will return to the anti-theft state. Some systems may also require manual reset.

6. AAnti-theft retractable pull boxes are widely used in:

Store display cabinets: When the goods are taken away, the alarm is triggered to prevent theft.

Equipment protection: such as protecting valuable equipment and tools from being stolen.

Home or office: Prevent valuable items from being stolen or moved.

Summary: The working principle of the anti-theft retractable pull box is based on the extension and contraction of the pull wire and the triggering of the sensor. When the item is illegally moved or disassembled, the change of the pull wire triggers the alarm system, thereby alerting the anti-theft monitoring personnel. In this way, the anti-theft telescopic pull wire box can effectively enhance the security protection of items and prevent theft.
