Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 to 8, the elevator door slider provided by the present invention comprises a connecting plate 1, two door slider connectors are arranged on the lower end surface of the connecting plate 1, a door slider 9 is arranged in the door slider connector, an insertion hole is arranged on the upper end surface of the door slider 9, an insertion block inserted in the insertion hole is arranged on the upper end of the door slider connector, a through hole is arranged in the insertion block, a circular convex hull matched with the through hole is arranged in the through hole, and the lower end surface of the connecting plate 1 is lower than the lower end surface of the door slider 9; the connecting plate 1 and the inserting blocks are integrally formed in a punching mode.

The door slider 9 of this technical scheme has the direction simultaneously, keeps spacing function, and when the door plant received the striking, more can protect door plant and people's safety. Through connecting plate 1 a whole to two door slider 9 junctions, simple to operate guarantees the plane degree of door slider 9 simultaneously, and the operation is more level and smooth and easy. The lower end face of the connecting plate 1 is lower than the lower end face of the door sliding block 9, so that the matching depth of the door sliding block 9 and the sill is increased, if the matching depth is 10mm, the number is increased to 18, the door sliding block 9 cannot be separated from the sill easily, and the safety of an elevator and personnel is guaranteed.
