Description

Technical Field

[0001] The utility model relates to the technical field of elevator devices, and particularly relates to an elevator external call box. Background Art

[0002] The elevator external call box is an important part of the elevator system and is used to call the car. It is installed on the wall of the passing floor. The elevator external call box in the prior art includes a push-button and a display screen. The user calls the elevator by pressing the button, and the display content of the display screen is the current floor value of the car and the full-load information.

[0003] The display screen of the existing elevator external call box is usually protected by a single-layer glass. When the single-layer glass is externally collided, the glass fragments are likely to directly contact the display screen, resulting in immediate damage to the display screen, affecting the operation of the elevator. In addition, the existing external call box is usually a cuboid structure with an open front, and the open front is equipped with a front cover. When repairing a fault in the internal circuit board of the existing external call box, the front cover needs to be removed first to repair the interior. The existing structure has problems of inconvenient maintenance and difficult disassembly and assembly, affecting the work efficiency of maintenance. For this reason, we propose an elevator external call box. Summary of the Utility Model

[0006] By adopting the above technical solution, when overhauling the circuit board, since a protection mechanism is installed on the shell wall of the panel shell, and the protection mechanism is composed of an external call box main body, threaded holes, locking bolts, L-shaped plates and connecting bolts. Since the box wall of the external call box main body and the plate wall of the L-shaped plate are connected through a locking bolt, the personnel loosen the locking bolt, and after the locking bolt is removed from the threaded hole, the L-shaped plate is taken out from the external call box main body. After the panel shell is separated from the external call box main body, since the circuit board is located on the inner box wall of the external call box main body, it is convenient to directly remove the panel shell to overhaul the circuit board.

[0007] Specifically, it further includes a reinforcement mechanism, and the reinforcement mechanism is installed on the shell wall of the panel shell.
