[0002] After some equipment stops working, the power distribution control system that supplies power to the equipment usually needs a period of time delay before it completely disappears. If the user opens the power distribution control system and devices at the moment the equipment stops The cabinet door of the power distribution control cabinet, because there is still residual voltage in the power distribution control system and device at this time, it is easy to cause harm to the user's human body. Therefore, in order to avoid the residual voltage in the power distribution control cabinet from causing harm to the human body, it is necessary to The door lock of the power distribution control cabinet is equipped with a door lock delay protection mechanism, but at present, the existing door lock delay protection mechanism usually realizes the delay protection through a certain mechanism of forward or reverse rotation of the lock body, that is, This time-delay protection mechanism requires the user to wait for a period of protection time for the delayed opening of the door lock when opening the door, but also requires the user to wait for a period of time for the delayed closing of the door lock when closing the door, which greatly consumes the processing time of the user. , reduces production efficiency, and also brings a lot of inconvenience to users

The invention discloses a delay protection mechanism for a door lock. The mechanism comprises a rotating wheel box and a button; an operation rod and a rotating wheel are arranged in the rotating wheel box; the operation rod is provided with a rotation pillar; the end face of the rotating wheel is provided with a groove in which the rotating pillar on the operation rod can slide and the groove consists of a section of circinate arc groove and a linear groove which is connected with inner and outer end points of the circinate arc groove; due to the adoption of the structure, when opening a door, a user needs to wait for a certain period of protection time of delayed unlocking of the door lock, so the user is prevented from opening a cabinet door under the condition that residual voltage exists in a distribution control system; the body of the user is prevented from being hurt, or other safety accidents are avoided; meanwhile, when the user closes the door, the mechanism can close the cabinet door in real time, and the user does not need to wait for a period of delayed closing time of the door lock, so convenience is brought to the user and production efficiency is improved.
Description
technical field [0001] The invention relates to a door lock time delay protection mechanism. Background technique [0002] After some equipment stops working, the power distribution control system that supplies power to the equipment usually needs a period of time delay before it completely disappears. If the user opens the power distribution control system and devices at the moment the equipment stops The cabinet door of the power distribution control cabinet, because there is still residual voltage in the power distribution control system and device at this time, it is easy to cause harm to the user's human body. Therefore, in order to avoid the residual voltage in the power distribution control cabinet from causing harm to the human body, it is necessary to The door lock of the power distribution control cabinet is equipped with a door lock delay protection mechanism, but at present, the existing door lock delay protection mechanism usually realizes the delay protection t...
