Problems solved by technology

[0002] At present, the elevator sills widely used in the market are usually made of aluminum or potassium materials. The cost of both aluminum and potassium materials is relatively high, especially not suitable for large-scale industrial production and use; on the other hand, aluminum Or the elevator sill made by Keng can not bear a large load, and its flexibility is poor, especially the angle part formed by the base plate of the sill and the sliding groove, because it is a right angle, the contact area with the elevator is small, and the force-bearing area Also smaller and can easily cause damage

Abstract

Disclosed is an elevator landing sill. The elevator landing sill is mainly characterized by comprising a base plate, a right dragging block, reinforcing ribs, clamping hooks, an ash leaking groove, a cylindrical hole, a left lower dragging block, an antiskid groove and kidney-shaped holes. The base plate is of a U-shaped structural style. The right dragging block is perpendicularly connected with the upper end of the right side wall of the base plate, and is of an L-shaped structural style. The left lower dragging block is perpendicularly connected with the upper end of the left side wall of the base plate. The antiskid groove is formed in the top surface of the left lower dragging block. The ash leaking groove is formed between the base plate and the left lower dragging block. The clamping hooks are arranged at the bottom of the ash leaking groove. The reinforcing ribs are arranged on the portion, close to the middle, of the outer wall on the left side of the base plate. The kidney-shaped holes are formed in the bottom surface of the base plate. The cylindrical hole is formed in the left lower dragging block.

Description

technical field [0001] The invention relates to the technical field of elevator sills, in particular to an elevator hall door sill for supporting and opening and closing elevator doors. Background technique [0002] At present, the elevator sills widely used in the market are usually made of aluminum or potassium materials. The cost of both aluminum and potassium materials is relatively high, especially not suitable for large-scale industrial production and use; on the other hand, aluminum Or the elevator sill made by Keng can not bear a large load, and its flexibility is poor, especially the angle part formed by the base plate of the sill and the sliding groove, because it is a right angle, the contact area with the elevator is small, and the force-bearing area It is also smaller and can easily cause damage. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an elevator landing door sill, which has the characteris...
