Description

Top flat side guide elevator landing sill structure

Technical Field

The utility model relates to an elevator manufacturing technology, especially a top flat side direction elevator layer door sill structure.

Background

The elevator landing sill mainly serves as the lower part positioning, landing transition and decoration of the landing door, the existing sill is suspended, but the form is poor in stability and rarely used, so that a guide anti-falling part is mostly arranged at the bottom of the landing door, for example, the patent publication No. CN106414303B, the elevator sill is composed of a plurality of components, for example, a 1 st supporting component fixed on a base and a 1 st surface component fixed on the 1 st supporting component are different components, and a 2 nd supporting component fixed on the base and a 2 nd surface component fixed on the 2 nd supporting component are different components; then, a space into which a retaining member provided at a lower portion of the door panel is inserted, i.e., a door slider groove, is formed by these components. Like the elevator sill that patent publication number is CN204022224U design again, including the sill body that has the elevator spout, on the sill body under the elevator spout, be provided with the bar groove that equals and be completely penetrating in the vertical direction with elevator spout length, be provided with a plurality of strengthening ribs in the middle of the bar groove.

The existing sills are in a working state as shown in figure 5, the structure of the former is easy to accumulate dust due to the fact that the door sliding block groove is opened upwards, even if the cleaning difficulty is very high, the cleaning is needed frequently, otherwise, the elevator door can be accelerated to wear the sliding block when being opened and closed, especially after the elevator door is clamped into a large foreign matter equivalent to the sliding groove, if the cleaning is not carried out in time, the door sliding block is damaged slightly, and if the cleaning is not carried out in time, the landing door is clamped heavily, so that the elevator cannot be normally used, and the safety hazard is caused by the clamping phenomenon of shoe heels wearing high-heeled shoes; although the latter through groove structure can make part of foreign matters leak downwards through the strip-shaped groove, the garbage leaking downwards can be accumulated in the elevator shaft, and more safe trouble removal can be caused when the foreign matters are tightly clamped with the strip-shaped groove in an interference manner.
