Description

Technical Field

[0001] This utility model belongs to the field of elevator safety technology, specifically relating to an elevator landing door anti-detachment device. Background Technology

[0002] An elevator landing door anti-detachment device is a device specifically designed to enhance the stability and safety of elevator landing doors, preventing them from falling off in unexpected situations (such as earthquakes, impacts, etc.), thereby ensuring passenger safety. This device typically contains multiple components, each with its specific function, working together to provide comprehensive protection.

[0003] In the prior art, document CN201922271133.3 discloses an elevator landing door anti-detachment device. This device, by setting an arc groove and a support rod on the surface of the landing door and connecting the other end of the support rod to the wall, increases the impact force that the landing door surface can withstand without affecting the opening and closing of the landing door. This prevents the landing door from bending and falling off the guide rail. Furthermore, by using the support rod to connect the landing door to the wall, the connection strength between the landing door and the wall is improved, thereby reducing the possibility of the landing door falling off and improving the safety performance of the landing door.

[0004] Existing elevator landing door anti-detachment devices may have problems such as complex structure, inconvenient installation and maintenance, and unsatisfactory protection effect. Traditional anti-detachment devices may lack effective protection, resulting in insufficient safety guarantee in emergency situations, increasing the risk of landing door detachment and threatening passenger safety. Therefore, an elevator landing door anti-detachment device is proposed. Utility Model Content
