Elevator parking lock, panel assembly and elevator calling board

Abstract

The invention relates to an elevator parking lock, a panel assembly and an elevator calling board. The elevator parking lock comprises an outer casing, a cam, a first sliding block and a second sliding block; first static splicing pieces and second static splicing pieces are arranged on the inner side of the outer casing; the cam is fixed on a lock cylinder located inside the outer casing; a third groove is formed in the periphery of the cam; the first sliding block is retractably arranged on the side wall of the outer casing to abut against the third groove in a clamped manner and be separated from the third groove, so that a first moving splicing piece is driven to abut against and be separated from the first static splicing pieces; and the second sliding block is retractably arranged on the side wall of the outer casing to abut against the third groove in a clamped manner and be separated from the third groove, so that a second moving splicing piece is driven to abut against and be separated from the second static splicing pieces. The states of two elevators can be controlled by the aid of the elevator parking lock, the elevator parking lock is convenient to operate and occupies small internal space of the calling board, the overall size of the calling board is reduced, and the mounting space, the mounting and dismounting costs and the production and manufacturing costs are reduced.

Description

technical field [0001] The invention relates to the technical field of elevator manufacturing, in particular to a parking lock, a panel assembly and an elevator calling box. Background technique [0002] The elevator call box is installed on the outer wall of the elevator landing and is used to call the elevator to the floor where the passengers are. Such as figure 1 As shown, the exterior of the call box is usually provided with a call button 11 ′ and a parking ladder lock 10 ′. The calling button 11 ′ is usually used to issue a calling command, and the parking ladder lock 10 ′ generally has two states of running and parking. When the switch of the parking elevator lock 10' is in the running state, the elevator can receive the call instruction issued by pressing the call button 11' and run according to the instruction; when the parking elevator lock 10' switch is in the parking state, the elevator will No longer receive the call command sent by pressing the call button 11...

AI Technical Summary

Problems solved by technology

However, setting two sets of parking ladder locks 10' makes the operation complicated, and takes up a large internal space of the calling box, resulting in a large overall structure of the calling box, taking up a large installation space, and increasing disassembly and assembly costs and manufacturing costs.
