Description

Technical Field

[0001] This utility model relates to the field of elevator door operator technology, and more specifically, to an adjustable elevator door operator. Background Technology

[0002] In the field of elevator technology, the elevator door operator is the core driving component for the opening and closing of elevator doors. Its performance is closely related to the overall operating efficiency, safety and reliability of the elevator door system. The traditional connection structure between the elevator door operator and the elevator door is mostly a fixed design. In the early stages of elevator installation, if the installation accuracy is high, this design can meet the basic door operator driving and door opening and closing requirements. However, in actual application, due to the complexity of the elevator installation environment, errors in the installation process, and wear and deformation of components after long-term use, the fixed connection structure has gradually revealed many drawbacks.

[0003] Fixed connection structures lack flexibility and are difficult to adapt to minor deviations during installation. When installing elevators, due to minor differences in building structure and inaccurate installation of guide rails, there may be a certain deviation in the relative position between the elevator door and the door operator. Fixed connection structures cannot effectively adjust for this deviation, which may result in uneven force on the door operator when driving the door to open and close, increasing the wear and tear on the door operator and door, and reducing the service life of the equipment.

[0004] With long-term operation, the connecting components between the elevator operator and the door panels may loosen or deform due to vibration, friction, and other factors. This alters the connection between the operator and the door panels, and fixed connection structures cannot compensate for or adjust for these changes. Consequently, this can lead to uneven door opening and closing, increased noise, and even safety hazards such as door shaking or jamming, severely impacting the normal operation of the elevator and the passenger experience. Therefore, we have made improvements by proposing an adjustable elevator door operator. Utility Model Content
