AI Technical Summary

Technical Problem

The drive shaft of existing swing doors is far from the center of the door, resulting in energy waste and large driving torque, and the lack of a support structure makes them prone to damage.

Method used

A novel elevator swing door was designed, which uses a drive mechanism to rotate the connecting shaft. The support plate and the fixed plate form a triangular stable structure to support the door body. The door is combined with a frosted finish and a buffer spring to reduce friction and collision damage.

Benefits of technology

It improves the stability and safety of elevator swing doors, reduces energy waste and wear, and avoids damage caused by collisions.

Abstract

This utility model relates to the field of elevator equipment technology and discloses a novel elevator swing door, including a swing door mechanism and a drive mechanism. The drive mechanism includes a base, an auxiliary support plate movably connected to the top of the base via a pin, a drive block movably connected to the inner side wall of the base, a connecting shaft movably sleeved on the top of the drive block, a support plate fixedly sleeved on the top of the connecting shaft, a fixed plate movably connected to the top of the support plate via a pin, the bottom of the auxiliary support plate movably connected to the top of the support plate via a pin, and the bottom of the fixed plate fixed to the top of the door body via bolts. When the door body is opened, the support plate, fixed plate, and base form a triangular stable structure to support the door body, while the auxiliary support plate further supports the support plate, preventing the door body from suddenly closing due to collision and causing damage, thus improving the stability and safety of the swing door.
