[0002] Safety contact edge, also known as bumper strip, is a sub-sensitive switch that looks like a flexible, bendable strip. Normally open logic, when triggered, these safety contact edges are pressed and deformed due to their softness, and the closed io type is transmitted to the SRC controller due to the sensing action, and the feedback is that the elevator has clamped someone.

DETAILED DESCRIPTION
[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

A clamping structure is arranged at the bottom of the insulating rubber skeleton 1. The clamping structure is an elastic rubber structure, and the clamping structure includes an upper clamping structure 81 and a lower clamping structure 82. The clamping structure shrinks at the connection point between the upper clamping structure 81 and the lower clamping structure 82. The diameter of the connection point between the upper clamping structure 81 and the lower clamping structure 82 is smaller than the diameter of the upper clamping structure 81 and the lower clamping structure 82.

When the elevator door touches a person or an obstacle, the insulating rubber skeleton 1 is squeezed, and the first hollow structure 2, the second hollow structure 6 and the third hollow structure 83 are deformed, so that the upper conductive rubber strip 3 and the lower conductive rubber strip 4 contact and conduct, close the circuit, and transmit it to the relay controller, and the elevator stops and closes to prevent people from being pinched. The relay controller controls the light strip 7 to emit light, which serves as a warning.
