Description

Technical Field

[0001] This utility model relates to the field of elevators, and in particular to a novel door lock structure for a side-opening hall door sill device in elevators. Background Technology

[0002] The landing door sill device plays a crucial role in elevator operation. It not only seals off the landing entrance and car entrance but also plays a vital role in ensuring passenger safety. As the outer door of the elevator, the landing door uses a mechanical locking device and an electrical interlocking system to ensure it is locked when closed, preventing accidental opening during elevator operation that could lead to falls or shearing accidents. The elevator door lock device must meet both mechanical locking and electrical verification conditions, allowing opening only when leveling. Currently, the active mounting plate assembly requires the installation of a door lock assembly, which must cooperate with the auxiliary contact assembly and also be able to open in emergencies or during maintenance. However, the current structural strength and safety are insufficient. Summary of the Invention

[0003] To address the aforementioned technical problems of insufficient structural strength and safety, this utility model provides a novel door lock structure for an elevator side-opening hall door sill device.

[0004] The technical solution of this utility model is as follows: A novel door lock structure for an elevator side-opening hall door sill includes a base plate assembly and a lock hook. The base plate assembly has a mounting seat at the top, a mounting cylinder in the middle of the mounting seat, limiting rubber on both sides of the mounting seat, a crossbar at the rear of the mounting seat, and a connecting plate at the front of the mounting seat. The connecting plate is bent inward in the middle and has a hollowed-out upper part. A fixed ball assembly is located on the left side of the connecting plate, a movable ball assembly is located on the right side of the front of the lock hook, an auxiliary lock hook is located on the inner left side of the lock hook, a configuration assembly is located at the bottom right side of the lock hook, and a downwardly bent mounting position is located at the mounting position, on which a contact assembly is located.

[0005] The mounting base has inclined surfaces on both sides, and the lower part of the connecting plate has three mounting positions arranged in a triangle. The lower part of the connecting plate is fixed to the middle of the active hanging plate assembly by bolts and nuts. The bottom left side of the locking hook is arc-shaped and curves downward. The back of the moving ball assembly is in a hollowed-out area, and the secondary locking hook has an inclined wall.

[0006] The base plate frame assembly and the locking hook are riveted together by a connecting pin in a hydraulic device. The connecting pin passes through the mounting ring of the locking hook and the self-lubricating bearing for fixation. The self-lubricating bearing is pressed into the mounting cylinder by the hydraulic device.

[0007] The technical solution of this utility model features a novel structure and a clever and simple design. The limiting rubber on both sides of the base plate frame assembly can limit the rotation angle. The configuration components can be increased or decreased. The base plate frame assembly is firmly fixed to the active hanging plate assembly through three mounting positions on the lower part of the connecting plate. The lower part of the connecting plate is a smooth surface with high compatibility. The active hanging plate assembly has pre-drilled mounting holes on the left, middle, right, and top to meet the installation and fixing requirements of different positions. The mounting base ensures strength and thickness. The inclined wall of the secondary locking hook and the smooth wall at the bottom of the card holder work together to ensure the separation of the insertion port and the insert. It can be used in emergencies or maintenance. The overall design is more robust than small equipment, and the structural strength and safety are greatly improved. Attached Figure Description
