Elevator sill

Abstract

The invention discloses an elevator sill capable of effectively preventing an elevator door from being disengaged out of a sliding groove. The elevator sill structurally comprises a sill body. The sliding groove which is opened upwards is formed in the sill body in the length direction of the sill body. A locking block is embedded into the middle part of the sliding groove. The upper surface of the locking block is not higher than that of the sill body. A locking space used for inserting a grab installed at the corresponding position of the elevator door into the lower side of a stopping block is arranged between the locking block and the bottom wall of the sliding groove. The elevator sill is matched with the elevator door which is additionally provided with the grab, and thus more safety is achieved. The elevator sill can be widely applied to various lifting elevators.

Description

Technical field [0001] The present invention relates to an elevator sill, in particular to an elevator sill for installing elevator doors so that the elevator doors slide in the sliding grooves. Background technique [0002] At present, the structure of the traditional elevator sill is relatively simple. It usually includes the sill body. The sill body is provided with a chute that matches the elevator door, and the bottom wall of the chute is provided with a foreign body penetrating the bottom wall to discharge hole. Because the chute of this kind of traditional elevator sill is shallow, its depth is usually about 20 mm, the safety performance is poor, and the elevator door cannot be well protected, so that in actual use, the elevator door may sometimes be Under the action of external forces such as the push of the worm, they came out of the ground, causing the people preparing to take the elevator to fall into the elevator shaft, causing a safety accident. Summary of the inve...
