Detailed implementation method

[0022] In this embodiment, referring to Figures 1-6 , the platform elevator safety edge structure includes a profile 2, a travel switch 3, a trigger switch 4, and an elastic piece 5. The profile 2 is arranged outside the bottom plate 1 of the elevator. One end of the elastic piece 5 and the travel switch 3 are both installed at a position near the edge on the bottom surface of the bottom plate 1; the trigger switch 4 is fixedly connected to the profile 2, the travel switch 3 is docked with the trigger switch 4, the trigger switch 4 is connected to the control system of the elevator, and when the profile 2 is pressed, the travel switch 3 touches the trigger switch 4 to control the elevator to make an emergency stop; the other end of the elastic piece 5 is connected to the trigger switch 4 to form a structure for driving the profile 2 to reset upward.

[0023] Except for the side facing the elevator screw rod where the profile 2 is not arranged on the bottom plate 1, the profile 2 is arranged on the left and right sides and the front edge, a total of three sides. The adjacent profiles 2 are fixedly connected by the corner connector 8 to form a semi-frame structure with a front opening for enclosing the left, right, and front three sides of the bottom plate 1.

[0024] An elastic piece 5 and two groups of travel switches 3 and trigger switches 4 are respectively arranged on the left and right sides of the bottom plate 1. The elastic piece 5 is close to the front to form a structure that can be triggered and reset on both sides and the front edge.

[0025] The elastic piece 5 is of an inclined structure, and the end connected to the bottom plate 1 is higher than the end connected to the trigger switch 3.

[0026] The elastic piece 5 and the travel switch 3 are respectively fixedly connected to the bottom plate 1 through the fixing piece 10.

[0027] An installation groove opening outward is arranged in the profile 2, and a light strip 6 is arranged in the installation groove. The light strip 6 irradiates outward to make the elevator obtain a lighting effect.

[0028] A lamp shade 7 is installed on the profile 2. The lamp shade 7 covers the light strip 6 to protect the light strip 6 and at the same time can play a diffusing role to make the light softer and more beautiful.

[0029] A light shielding piece 9 is installed at the corner position of the adjacent profiles 2 to cover the end of the profile 2 to prevent the light from emitting from the end of the profile 2.
