Elevator door sill slider device

Abstract

The invention relates to a sill slider device of an elevator door. The sill slider device is arranged in a sill groove of an elevator and comprises a sill slider and a connecting plate. The connecting plate is connected to the slider; the sill slider is arranged in the sill groove, at least one side, which corresponds to a groove surface of the sill groove, of the sill slider is provided with an elastic border, the borders are in contact with the corresponding groove surfaces of the sill groove in a pressure manner and accordingly movably elastically deform towards the inner sides of the borders, and the sill slider can be seamlessly slidably connected into the sill groove. The sill slider device has the advantages that the sill slider is provided with the elastically deformable borders, and can be seamlessly slidably connected into the sill groove, seams between the slider and the sill groove can be constantly and assuredly prevented even if the corresponding borders are abraded due to frequent sliding of the slider, and the elevator door can assuredly stably run without noise; the sill groove can be cleaned under the sliding action of a cleaning element, so that jamming faults due to garbage deposits in the sill groove can be prevented; the cleaning element is quite convenient to replace.

Description

technical field [0001] The invention relates to elevator accessories, in particular to an elevator door sill slider device. Background technique [0002] Generally, the upper and lower ends of the elevator door are respectively connected to the pulley and the sill slider. The pulley at the upper end of the elevator door rolls in the guide rail on the upper sill side of the elevator, while the sill slider at the lower end of the elevator door is in the sill groove on the lower sill side. slide. [0003] Existing elevator doors have the following deficiencies: one is that the slide block is a rectangular entity, in order to slide along the sill groove, a certain gap must be left, and the gap increases along with the sliding wear of the slide block. If the elevator door is enlarged, the elevator door will shake during operation, even if the elevator door is not running smoothly, and it will also generate noise; secondly, the elevator enters and enters the goods through the...

Problems solved by technology

[0003] Existing elevator doors have the following deficiencies: one is that the slide block is a rectangular entity, in order to slide along the sill groove, a certain gap must be left, and the gap increases along with the sliding wear of the slide block. If the elevator door is enlarged, the elevator door will shake during operation, even if the elevator door is not running smoothly, and it will also generate noise; secondly, the elevator enters and enters the goods through the door sill, and the sill groove will accumulate garbage. The current sill slider cannot clear the garbage out of the sill groove, resulting in jamming failure of the elevator door during operation
