Description

TECHNICAL FIELD

[0001] The utility model relates to elevator structure, concretely relates to a grooveless elevator sill. BACKGROUND

[0002] During the door panel switch door operation, the upper part and the lower part need to limit the running track of the door panel, the upper part is the door head effect, and the limiting control of the electrical part is included. The lower part is the guiding limiting effect, the door sliding block is connected and fixed with the door panel through the aluminum alloy sill groove, the sliding block is limited and runs in the track in the aluminum alloy sill groove, so that the door panel runs horizontally and vertically.

[0003] The sliding block groove of the existing elevator sill is designed on the upper surface of the sill, the sliding block directly contacts the sliding block groove of the sill up and down with the door panel, the biggest disadvantage is that people or trolley goods entering and exiting the elevator can easily bring sand, cigarette butts and other foreign matters into the sliding block groove of the sill, which can easily cause the door opening and closing to be blocked, the door opening and closing is not in place due to the foreign matters blocking the door opening and closing, the door lock contact point is not in good contact, which can easily cause the elevator failure, and the phenomenon of people being trapped or the elevator not running occurs. In view of the above problems, the application number CN201921330300.0 discloses a grooveless elevator sill and elevator door assembly, the traditional sill sliding block groove is changed and designed on the side surface of the lower part of the sill, the sliding block connecting plate is bent and deformed, and the new type of sill sliding block groove is matched, so that the door panel normally runs. This design does not need to worry about the elevator failure caused by the foreign matters falling into the sill groove and causing the door of the elevator to be not in place, and the front surface of the elevator sill is free of the sliding block groove, so that the phenomenon of the door lock being not in good contact due to the sliding block being blocked and causing the elevator to stop occurs, the root cause of the door failure is greatly reduced, and the door failure rate is greatly reduced. But there are still the following problems, the sill body in the utility model is welded or fixed by screws by using multiple plates, so that the sill body has the stress concentration problem caused by multiple assembly segments, the overall rigidity and anti-deformation capacity are not high, and the structure stability cannot be strengthened. SUMMARY
