Description

TECHNICAL FIELD

[0001] The utility model relates to an improved elevator sill structure, in particular to a stainless steel layer door sill assembly with a hook. 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 ground below the layer door and connected with the building foundation and the elevator assembly. Therefore, structural improvement is needed. SUMMARY

[0003] The utility model aims at overcoming the above-mentioned deficiencies in the prior art and providing a stainless steel layer door sill assembly with a hook.

[0004] The utility model discloses a technical scheme for solving the above-mentioned problems. The stainless steel layer door sill assembly includes a sill part and a slider part. The sill part is fixed to the ground below the layer door, and the slider part is connected to the bottom of the layer door and is slidably arranged with the sill part. The sill part includes a stainless steel base and a profile groove. The stainless steel base is shaped as a container structure with a flat bottom and an open top. The profile groove is upwardly formed with a sill groove and is fixed in the stainless steel base. The sill groove is formed with a hook-shaped groove. The slider part is formed with an anti-extrusion hook. The anti-extrusion hook and the hook-shaped groove are oppositely arranged and slidably work together. The sill assembly uses the cooperatively arranged sill part and slider part. The sill is formed by combining structures made of different materials. The stainless steel base provides a structural foundation for the formed structure of the sill. The stainless steel is strong, durable, and has good forming quality. The profile groove can be formed into a groove structure with higher precision and a hook-shaped groove that can prevent extrusion. The performance of the elevator door in preventing extrusion is improved.

[0005] Further, the stainless steel base is formed by bending stainless steel material into a structure with a cross-section of a "U" shape, a horizontal support edge is formed at the top end of the stainless steel base, the profile groove body is supported on the support edge, the front side of the stainless steel base is provided with a foot guard mounting position, the rear side thereof is provided with a stand fixing position, and the bottom thereof is provided with a bottom mounting position.

The anti-disengagement groove is obliquely upward, and when the door is subjected to lateral force, the anti-disengagement groove guides the anti-disengagement hook to move to the groove bottom of the anti-disengagement groove, thereby achieving good anti-disengagement effect.

[0007] Further, the stainless steel panel is a flat plate structure with a smooth surface, and an identification is printed on the stainless steel panel. The stainless steel panel is flush with the upper surface of the profile groove body. The stainless steel panel is decorated on the surface, which is coordinated with the overall decoration of the elevator car.
