Technical Field
[0001] This utility model relates to the field of door lock and door knife technology, specifically a door knife with a car door lock for inclined elevator doors. Background Technology
[0002] Inclined elevators are becoming increasingly widely used. The elevator's operating angle varies depending on the height of the mountain. The elevator door operator must have door blades that can open the landing door locks at different angles, and also ensure that the car door cannot be opened when not at a landing. Currently, most systems use a landing-stop chock-type unlocking mechanism, which has problems such as large on-site deviations and difficulty in adjustment. This device integrates the door lock and door blade into one unit. The door blade angle can be adjusted according to the elevator's operating angle, resulting in a more compact design and wider versatility.
[0003] Currently, the existing system uses separate mechanisms for the angled door operator and the car door lock. The car door lock is mounted on the door operator and has a trigger wheel. A striker is installed on each floor. When the elevator arrives at a floor, the striker activates the trigger wheel, allowing the car door to open simultaneously after the door operator unlocks the floor door lock. However, this existing technology requires a striker for each floor, which can lead to significant deviations between the striker and trigger wheel due to the distance between floors. This necessitates repeated adjustments. Furthermore, the positions of the striker and the independent car door lock need to be constantly adjusted to meet the force direction requirements for opening and closing the doors. Therefore, improvements to the existing technology are needed. Utility Model Content
