TECHNICAL FIELD
[0001] The utility model relates to an improved elevator sill structure, in particular to a stainless steel layer door sill with hooks. BACKGROUND
[0002] The sill is an elevator assembly installed below the elevator door and leveled with the ground. The slider at the lower part of the elevator door is matched with the groove on the sill to provide linear guidance for the opening and closing stroke of the elevator door. The sill can be made of various materials. In high-quality elevators, the main material of the elevator car is stainless steel or other materials. Therefore, the sill also needs to be matched with stainless steel material. The traditional stainless steel sill is usually formed by simple bending. However, the turning angle of the bending piece is limited, and the formed groove cannot be too small, otherwise it cannot be formed. Therefore, it performs poorly in the anti-extrusion test. In some cases, the elevator door may be stuck due to extrusion. Therefore, improvement is needed. The layer door sill needs to be installed on the building ground below the layer door and needs to be connected with the building foundation and the elevator assembly. Therefore, structural improvement is needed. SUMMARY
