Description

Technical Field

[0001] This utility model relates to the technical field of escalator emergency stop devices, specifically an escalator safety linkage emergency stop device. Background Technology

[0002] An escalator safety linkage emergency stop device is a safety device specifically designed for escalators. It is intended to quickly stop the operation of the escalator in an emergency to reduce potential dangers and injuries. It is usually located near the entrance and exit of the escalator, in a prominent and easily accessible position. These buttons are usually red so that they are easy to identify in an emergency. When a passenger or staff member presses the emergency stop button, the system will immediately cut off the power to the escalator and stop its operation.

[0003] Common escalator safety linkage emergency stop devices have numerous internal circuits and poor heat dissipation. High-temperature environments can affect the performance of electrical components, leading to slower response speeds or malfunctions, thus reducing the reliability of the emergency stop device. Prolonged exposure to high temperatures accelerates the aging of electrical components, shortens their lifespan, increases the frequency of maintenance and replacement, and raises operating costs, all of which have adverse effects on users. Therefore, we propose an escalator safety linkage emergency stop device. Utility Model Content
