The invention discloses a removable cover plate locking device for an escalator or a moving sidewalk. A key matched with a key hole is inserted in the key hole and then is rotated (namely a core bar is rotated) to drive a spray nozzle to rotate, so that the spray nozzle is inserted in a lock hole of a frame to lock the removable cover plate on the frame; and while the key is rotated in the opposite direction, the core bar is rotated to drive the spray nozzle to be released from the lock hole to unlock the removable cover plate (namely the removable cover plate is opened from the frame). Through the removable cover plate locking device, the movable cover plate is locked and unlocked with the frame, and the removable plate is unlocked only by the key, so that the removable cover plate is prevented from being stolen after being opened by non-professionals, which ensures the use safety of the escalator or the moving sidewalk.
Description
[0001] technical field [0002] The invention relates to a locking device for movable cover plates on escalators or moving walks. Background technique [0003] In the prior art, the movable cover of the escalator or moving walk is covered on the frame, and some are fixed by screws, so that the movable cover can be opened by simple operation, and the machine room will be exposed when the movable cover is opened. Space, the space of the computer room is generally small, and there are rotating parts, it may be dangerous for non-professionals to enter. And the movable cover plate is easy to open and also gives criminals a chance to steal the movable cover plate. When the movable cover plate is missing, pedestrians may fall and cause danger. Contents of the invention [0004] The purpose of the present invention is to provide a device for locking the movable cover on the escalator or moving walk, so that the movable cover can only be opened by a key, and the movable cover...
