Abstract

The invention provides a pressing plate locking device comprising: an isolation cover, wherein the isolation cover is detachably arranged at the outside of a pressing plate; a locking component, wherein the locking component is arranged on the isolation cover, and the locking component has a locking state and an unlocking state; a magnetic force component, wherein the locking component is in driving connection with the magnetic force component and drives the magnetic force component to switch between a first state and a second state, the magnetic force of the magnetic force component in the first state is greater than the magnetic force of the magnetic force component in the second state, when the locking component is in the locking state, the magnetic force component is in the first state, the isolation cover is attached to and locked on a base where the pressing plate is installed through the magnetic force component, and when the locking component is in the unlocking state, the magnetic force component is in the second state, and the isolation cover can be separated from the base. The pressing plate locking device provided by the invention solves the problem that the pressing plate locking device in the prior art cannot safely and reliably isolate the pressing plate.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to a pressing plate locking device. Background technique [0002] The pressure plate is a common power wiring device. Multiple rows are installed on the metal base in the protection screen or the measurement and control screen, and often there are multiple rows of pressure plates with different intervals installed on the base together. Usually, the same row of pressure plates The pressure plate belongs to the same compartment. [0003] When the protection device needs to be overhauled, it is often encountered that there are multiple rows of pressure plates in the protection screen or the measurement and control screen, and the pressure plates do not belong to the scope of work, or the devices in the work range are related to other operating protection equipment circuits, which requires Isolate the operating pressure plate. If the isolation work is not done properly, it may cause malf...
